#sourcechipglen#The analysis of the LED panel lamp cost
The LED panel lamp cost is determined by various factors. Our simple analysis for everyone.
A, LED lamp bead cost. This is a relatively fixed, depending on the technology level of the whole industry, but also the general customers are purchasing Taiwan or American brand, price cannot control. Even if the purchase price is different, the gap is small. So, want to in this part of reduce cost, more difficult.
Two, border. The border is usually aluminum alloy material, which belongs to the futures prices, relatively large changes, according to the current market, basically belongs to the bullish trend.
Three, the driving power supply. LED light panel power supply, a mature industry, the price also is more transparent, the difference lies in the customer requirements of high or low and there is a little gap. But now there is a fireproof ultrathin PC material, can do 1.0mm fireproof, either through the UL certification, but also can reduce the weight of power effectively, and improve the flexibility of design. In improving the performance of the products, reduce the cost of.
Four, the light guide plate. The light guide plate has size and thickness of different, generally is 4mm and 6mm. 6mm mature, light efficiency in general can do more than 85%, the price is relatively expensive, occupied the whole lamp at least cost more than 25%. 4mm the price will be cheaper than the 6mm a little bit of money, but 4mm technology is not very mature, can do the manufacturers, not many.
Five, the diffusion plate. The diffusion plate material determines the price. Currently on the market there are PC and PMMA two. PMMA was at least 30% cheaper than PC. But there is a drawback, is PMMA relatively brittle, the thinnest can do 2mm, and PC to 1.0---2.0, and the toughness is good, the assembly is convenient. And can do fireproof grade 94V0 and 94V2.

#sourcechipglen# LED lighting market share will have big growth in 2014
After three years of downturn, LED industry prospects seem to be improved next year; it’s mainly because the growth of general lighting, and also the demand for backlit of tablet PC. UBS Global Asset Management report analyzed that if calculate by chip area, the general LED lighting demands will grow 62%, also suppose the same price decline rate, the LED lighting revenue in year 2014 will grow 37%. In other words, LED lighting penetration rate will increase to 9% next year from 3-5 % of this year, and estimates will drive the LED chip demand growth by 25%, while the traditional incandescent lamp will be to reduce 5% annually.
UBS pointed out that in the lighting market, the home lighting with the lowest market share, that because the LED light bulb was too expensive in the past years, home facelift need take years to recovery, but now the situation is changing, the LED bulb price falls, governments continue to ban incandescent bulb, plus the overall global economic recovery, all those factors will encourage the growth of LED lighting. UBS estimates that global household LED lighting revenues will grow 90% next year, much higher than the 37% of commercial lighting and 57% of industrial lighting.
International lighting manufacturers such as Philips and Osram only outsource the downstream packaging module in the past. UBS analyst Fredric Stahl believes that due to the substantial increase in demand of LED lighting, such manufacturers may consider to adopt Asian LED chip on the upstream end so as to improve price competitiveness.
As backlight market, TV market has been declining, UBS noted that the penetration rate of LED TV grown from 75% to 95% this year, but the number of chips for each TV has greatly reduced by 25% (due to the use of Direct Illumination-type LED Backlight reduce the LED quantity). Fortunately, there will be slightly improvement in 2014 due to the larger size TVs, and the popular of high-definition TV such as 4K*2K. UBS estimates that TV backlight LED proportion will reduce to 16% and 13% the next two years from 36% this year.
Tablet PC LED demand will surge 90% next year, mainly drove by the Apple iPad, and coupled with improved resolution and tablet PCs are still in the growth stage. UBS estimates that the Tablet PC representing LED chip demand will reach 24% in 2014.
#sourcechipglen# Russia encourages Chinese companies to set up LED factories in Russia
Gruzdev Alexey, the representative of Trade Representation of the Russian Federation in the People’s Republic of China, said in Russian and the CIS countries’ Lighting Market Analysis and Channel Strategy Conference that “In lighting products, China has always been the largest supplier of Russia.” Along with Russian accession to WTO, prohibition of sale incandescent bulb, Winter Olympics in Sochi this year and World Cup in 2018, Russia has great demand on LED lighting. Russia welcomes the strength Chinese enterprises to participate the LED renovation projects for public institutions of Russia and CIS countries, large industrial and mining enterprises, sports stadiums and others.
According to Gruzdev Alexey’s introduction, Russian LED industry was developed rapidly last year, the growth rate is 250%, and LED lighting accounted for 10% of market share. Data shows that the Russian LED bulbsales in 2013 are 1 billion units, with total sales of 40 billion rubles (about 1.11 billion US dollars). As the Russian government introduced a series of measures to promote energy-saving light sources, it is expected that Russia LED lighting market share will increase to 35% of whole lighting industry in 2016.
Last year, Chinese LED products export to Russia and CIS countries is $ 800 million, which Russia accounted for 75.74%. China LED products accounted for more than 40% of Russian market.
“We strongly encourage Chinese advanced enterprises to invest in Russia, there many Chinese enterprises may worry about the problem of investment environment, tax, legal protection and other issues, the Russian government has done a lot of work in the past few years, and have improved greatly in company registration, investment, banking services, tariffs and other aspects.” Gruzdev Alexey said.
“In my opinion, the preferential policies offered in Russia are more favorable than Chinese implementing policies.” Gruzdev Alexey believes that since China began LED very early, so the preferential policies have been canceled in a lot of economic zones, while Russia is now actively promoting these policies.
He said that if set up factories and registered enterprises in Russia, besides providing favorable conditions, the Government will allocate some financial support, and different regions have different policies. “For example, including at least five years of free land usage, general profit tax is 20%, in order to encourage Chinese companies to set up factories in Russia, this ratio may be adjusted. Additionally, the local government is also with positive attitude on simplifying administration, shortening the approval process, reducing approval procedures, etc.”

#sourcechipglen# The design of LED bulb lamp
1. Brightness to almost incandescent lamp. Incandescent lamp wattage usually only, do not pay attention to the lumen. LED bulb lamp not only has the wattage, and luminous flux. In the same light, LED bulb relative to the power of incandescent lamp can save 10 times. One thing to note, at present, from the LED bulb lamp light efficiency and heat dissipation, it also can't do more than 10 watt.
2. Appearance should be similar. Usually the incandescent lamp to pear shaped, so LED bulb lamp should be designed into a pear shaped.
3. The volume and weight. Because LED requires constant and radiator, LED bulb weight is greater than incandescent lamps.
4. The lamp cap to the same. LED bulb lamp holder types must be the same as incandescent lamp.
5. Supply voltage should be the same. The voltage of each country is different, but the LED bulb lamp generally use the switch power supply, so it can be wide supply voltage 100-240V.

The LED Lighting Deal Landscape Is Growing, But Not Matching Expectations.sourcechipglen
Although significant consolidation has already occurred across the LED value chain, further consolidation will be required for the market to mature to a stable state.
Some of the drivers of this process will be achieving economies of scale, cost reductions, sustainable market share and access to innovative IP to meet rising output requirements. This will further increase the likelihood of deal activity to 2018. Memoori recently released a research report on investment activity in the LED sector, finding that deal activity has not met expectations set a couple of years ago.
Both overall VC Investment flows and cleantech-specific VC funding were on a downward trend in 2012 and 2013; however, of all the cleantech sectors, energy efficiency companies continued to attract the most VC investment throughout 2013.
According to data from the Cleantech Group, the sector soaked up 19 percent of all venture investments during the first six months of 2013. The number of energy efficiency deals rose 45 percent in the second quarter for a total of 79 through June.
Princeton University pursues LED-centric campus-wide lighting upgrade.sourcechipglen
August 20, 2014
By Maury Wright
Editor in Chief, LEDs Magazine and Illumination in Focus
Princeton University has announced the start of a project that will see more than 100,000 fixtures across the New Jersey campus upgraded to LED technology by the end of December 2016. A member of the elite Ivy League of schools that date to colonial American times, Princeton believes that adopting LEDs can contribute 16% to the Princeton Sustainability Plan goal of reducing the campus carbon footprint to 1990 levels prior to 2020.

"The Lighting Efficiency Upgrade Program can transform Princeton's lighting systems to one of the most modern, reliable, efficient, and environmentally responsible of their kind," said campus energy manager Bill Broadhurst. "The recent progress made in LED technologies also has allowed these projects to be good investments financially."
The university had tested LED lighting in a number of locations over the past few years including parking areas, a gymnasium, and select academic buildings. The project that kicked off in July will cover the entire campus. Already the project has resulted in retrofits in Icahn Laboratory, Fine Hall, parts of the Engineering Quadrangle and 701 Carnegie Center.
A number of universities around the globe are finding that LED technology can both improve campus lighting and reduce costs in terms of energy usage and maintenance.The University of North Carolina has begun to renovate 13 campuses within its system. Dartmouth University reports that a retrofit in its Baker Berry Library delivered 66% energy savings. Moreover, MIT's iconic Great Dome is now lit with LEDs.
In the Princeton case, many of the early upgrades will come in the form of LED replacement lamps as the nearby photo illustrates. But ultimately the project will involve luminaires as well. Indeed, one project completed during trials was a complete retrofit of fluorescent fixtures in the university's Dillon Gymnasium with LED luminaires.
The university is shooting for a baseline 50% reduction in energy use with much of the legacy lighting comprising fluorescent products installed in a prior campus-wide retrofit two decades back. Moreover, the upgrade with longer-life LEDs will allow the university to eliminate the need to properly dispose of 60,000 lamps each year that contain mercury, and five tons of other waste including ballasts.
"In addition to the significant cost savings, revenues, and credits associated with using LED technology, the lighting upgrades also will lower the university's maintenance costs due to LEDs' long expected life," Broadhurst said. "The safety of the Princeton Facilities staff also will be enhanced by reducing the amount of time workers spend climbing ladders to replace thousands of burnt-out lamps each year."

China led bulb lamp in North Korea hot.sourcechipglen
Recently China led bulb lamp in North Korea hot, more and more North Korea people panic buying Chinese manufacturing LED bulb lamp. Although LED bulb price is expensive, but compared with the traditional incandescent lamp, LED lamp has high efficiency, energy saving, which for a severe power shortage countries is undoubtedly the best choice. So, a lot of the North Korea people are willing to choose the high price but can work properly at low voltage LED bulb lamp.
Because North Korea electric power shortage, cannot provide 220V voltage required for the normal work of the general household electrical appliances, but the LED lamp can light normally under the condition of low voltage, so LED lamp sales soared in North Korea. In the summer peak electricity, the North Korea households voltage is only 170V, lower in winter to 100V. The incandescent lamp can not provide normal lighting required at voltages below 220V, but the LED lamp is different, even if the voltage is lower than 70V, it can still normal lighting. So, althoughChina led bulb lights price higher than incandescent lamp two times, the North Korea people still willing to buy LED lamp.
Another advantage of LED lamp is long service life. High power LED lamp life of up to 50000 hours, the incandescent lamp life of only 2000 hours, fluorescent lamp life 15000 hours, compared with them, LED lamp life advantage prominent.

LED spot light fittings - lens design.sourcechipglen
As everyone knows, LED downlight product turnover speed is be struck dumb. The development of LED spot light fittings - lens is also make a spurt of progress. But overall, the attention on the market or lamps visual effect and light effect, so the lens design to meet the three requirements: one is the novel lens shape; two is effective and transparent lens rate; three is the visual effect of lens and lamp fitting. According to the above three requirements, there are three main lens design in the common market:
First, the lens side by free surface design, the light exit surface uses compound eye design, light angle adjustable 250-600, the general use of PC material, can be used for the COB light source lamp surface diameter 14mm, the effective optical transmittance can reach to maximum 94%.
The second lens using external face scales, the light exit surface center uses compound eye design. The third lens using external surface, nearly smooth, The light exit surface uses compound eye design.
The second and third lens generally use PC material, high temperature tolerance, the light source can be used modular SMD light source or COB light source, a light adjustable 300-600, uniform light output. Apparent, SMD light source can scattering by compound eyes , visual effect is similar to COB. Expand the light source of selective.
Thus, LED spot light lens design has been gradually to aesthetics and versatility direction, how to improve the effective transmittance of the lens spotlights, spot uniformity, universal design will become mainstream.
LED ceiling light lamp beads.sourcechipglen
About the use of LED ceiling light lamp beads. Power greater of Ceiling Light than 30W generally use 1W LED lamp beads, power is less than 30W Ceiling Light generally use small power LED lamp beads (eg 3020,3014,3528, etc.). Recommended for low-power SMD LED, easy to heat, but also improve the luminous uniformity.
Lamp beads can be arranged according to their shape, such as square led ceiling light, lamp beads arranged in a square; If the shape is round, then arranged in a circle. Even so, the arrangement of lamp beads still there are many ways, the internal structure of a typical LED ceiling as shown.

The color temperature of LED down light to absolute temperature "K" to represent. The color temperature: the color and the blackbody source emitting light at a temperature radiation light color is same, the temperature of the blackbody called the color temperature of light source.
Color temperature >5000k: the color is cool white type (Bluish white light), cold atmosphere effect;
Color temperature in the 3300-5000K: the color is white, no obvious visual psychological effect in this kind of color; it is called the neutral color temperature;
Color temperature <3300K: light color is warm white (Reddish white light), warm atmosphere effect;
Color temperature and brightness: in the high color temperature light, such as brightness is not high will give people an eerie atmosphere; in the low color temperature light color, brightness is too high will give people a stuffy feeling.
Comparison of LED downlight light color: Using two kinds of light color difference is very big of light in the same space, there will be layered effect, Light color difference is large, In the brightness layered effect at the same time, but also can obtain layered effect color.

The status of LED down light market.sourcechipglen
After years of development, LED down light has been widely applied in engineering, the field of decoration, replaced the traditional downlight. In the field of LED lighting, lamp can be said that the popularity of the highest category, because of its technical content is not high, no admittance threshold, who can produce, resulting in uneven quality, so the current the status of LED down light market is still relatively confused. At the same time, the current price of LED down light is very transparent, from the chip, shell, packaging and other accessories cost, the dealer basic understanding be crystal clear, but due to the low barriers to entry, producers are numerous, competition is intense, therefore LED downlight profits compared to other lighting products much lower.
Downlight generally used in shopping malls, office, factory, hospital and other indoor lighting, installation is simple and convenient for people to love. LED down light inherits all the advantages of traditional downlights. Small heat, electricity saving and long service life, maintenance cost minimization. Early LED downlight with LED beads expensive, the overall cost is high is not acceptable by the customers. With the reduction of LED downlight chip prices and cooling technology improved, laying a solid foundation for the LED down light into the business world.

LED Light Bulbs Shine Brighter, Longer.sourcechipglen
Lighting options have improved greatly since incandescent bulbs first came around. Instead of using lots of energy to produce a comparatively small amount of light, LED light bulbs convert most of their energy into light. It's no longer necessary to settle for CFL bulbs that take 30 seconds to warm up and turn on fully. LED bulbs turn on immediately. Additionally, because these lights last for at least 25,000 hours, homeowners can put away the ladder since they will need to replace bulbs so infrequently. TopTenREVIEWS has just released a comparison of the best LED light bulbs that are comparable to a 60-watt incandescent bulb. They looked for the LED bulbs that provide the most light, use the least amount of energy, last for the longest amount of time and make a room feel warm and naturally lit.
"LED light bulbs keep getting better. They last longer, shine brighter and continue to be less expensive. Compared to incandescent and CFL bulbs, they're more efficient, safe for the environment and you enjoy the same warm glow that an incandescent would produce," said Lecia Monsen, Managing Editor of TopTenREVIEWS.

How Do LED Light Bulbs Work?sourcechipglen
If you're savvy about saving money and the environment, you've probably taken an interest in LED light bulbs because they're even more energy efficient and environmentally safe than CFL and incandescent bulbs. Many LED bulbs also have unique designs that loosely resemble traditional incandescent bulbs but have embellishments around the bulb itself.
More Light, Less Heat
Light-emitting diodes (LED) are semiconductors. As electrons pass through this type of semiconductor, it turns into light. Compared to incandescent and CFL bulbs, LED lights are more efficient at turning energy into light. Therefore, less of the energy radiates from the bulb as heat. This is why LED bulbs are cooler during operation than incandescent and CFL bulbs.
As the light-emitting diodes create light, they warm up quite a bit for their size. LEDs are heat sensitive, so it's important that the heat move away so that it doesn't damage the semiconductors. In order to do this, these lights need a system to keep cool. Most LED lights have a heat sink plate that moves the heat away from the light-emitting diodes through the heat sink plate. Manufacturers make the heat sink plate out of a variety of materials, but it's commonly made from aluminum. Frequently, the heat sink becomes part of the design of the bulb.
An LED light bulb's heat sink usually weighs several ounces and can become hot once you turn on the light. From the heat sink plate, the heat moves into the air surrounding the bulb. If you place the bulb in an enclosed fixture, it keeps the heat from effectively moving away from the heat sink, raising the temperature around the light-emitting diodes. This, in turn, causes the LEDs to overheat, shortening the life of the bulb.
Directional Light
Many LED bulbs have light-emitting diodes that all shine in one direction. This results in a bulb that directs most of its light toward the top of the bulb. If you place this type of bulb in a table lamp, you can see that most of the light ends up on the ceiling with very little refracted onto the table. In an attempt to make LED bulbs more like incandescent bulbs, omni-directional LED lighting is becoming more common. This lighting distributes the light evenly around the bulb. Commonly, it's done by bouncing the light off reflective plates inside the bulb.
An Aging Bulb
As LED light bulbs get older, they don't just burn out. Instead, they grow dimmer. The industry standard for LED light bulbs is that they should last for at least 25,000 hours with at least 70 percent as much brightness as they have when they are new. Below 70 percent is the point at which the industry decided the decrease in brightness is noticeable.
LED light bulbs are relatively new on the market, so they haven't been through the test of time – especially those that boast a lifespan of 50,000 hours. Although most of these lights last for about 25,000 hours, their warranties only cover about three years. This is perhaps because if you run the LED lamp continuously, it will only stay within the 70 percent range for a little less than three years. However, if you look on the Lighting Facts label of many LED lamps, it gives a life based on years. This is because the industry standard is three hours of use per day instead of 24 hours.

LED Light Bulbs: What to Look For.sourcechipglen
When you're shopping for an LED light bulb, it's important to find one that provides the amount of light you need, as well as the color of light you like. You'll also want to consider how the light emits from the bulb, and the dimension of the bulb and base. The bulbs in this review are comparable to a 60-watt incandescent bulb.
Features
A standard 60-watt incandescent bulb puts off about 800 lumens. The more lumens, the brighter the light is. LED light bulbs provide many lumens for few watts compared to incandescent bulbs. Since this is the case, it's better to find a bulb that has low wattage but high lumens because it will save you on your energy bill.

Since this is the case, it's better to find a bulb that has low wattage but high lumens because it will save you on your energy bill.
You also want to find an LED light bulb that offers a long lifespan. Most offer between 25,000 and 50,000 hours of light. When you look at a Lighting Facts label on the light bulbs, they typically list the lifespan in years. This is based on a standard of using the light for three hours per day each day of the year.
When you're looking for an LED light bulb, another thing to consider is the color of the light. Depending on where the light bulb lands on the color temperature spectrum, lights can be all colors: red, yellow, green, blue and shades of white. The shades of white range from warm to cool white. The lower the color temperature, the more yellow your white light will appear. If the light is higher on the color temperature scale, it will appear to cast a cool, bluish hue. Another aspect of the color is the color rendering index (CRI). The higher the CRI number, the greater the number of objects lit by the light bulb that will appear natural.
The bulb should also be UL listed and comply with part 15 of the FCC as a Class B device, meaning it won't interfere with radio frequencies. It's also an added bonus if the light bulb is Energy Star Qualified.
Design
The dimensions and weight of LED bulbs are not the same as a standard incandescent bulb. LED light bulbs are on average a quarter of an inch taller. The average diameter of these LED lights is similar to that of incandescent bulbs but varies depending on the model. LED lights are also heavier than incandescent bulbs, so you'll want to be sure that your light fixture can support the extra weight.

Most LED light bulbs can't be fully enclosed in a light fixture because heat decreases the life of the light bulb. If you plan to use your LED light bulbs outside, you'll first want to verify that they can withstand damp outdoor conditions. If you want to dim your lights with an LED light bulb, you'll need to have one that the manufacturer has specifically designed to perform as a dimmer.
The beam spread is another thing to consider. While incandescent lights put off light in all directions, LED lighting typically sends its light in one direction. The best LED light bulbs that are comparable to 60-watt incandescent bulbs distribute the light around the bulb as well as from the top.
Help & Support
Chances are you won't need to be in contact much with the manufacturer to use your light bulbs. However, having a practical return policy and warranty are importance since these light bulbs cost more than incandescent and CFLs. A good LED light bulb should come with at least a three- to five-year warranty.

LED lighting presents a new, more environmentally friendly option. It's long lasting and can save you money over an extended period. These lights are heavier than other lighting options, and the bulb is on average a little taller than a standard light bulb; however, the base can fit in standard light sockets. These lights will keep going long after incandescent and CFLs would have stopped working, and they'll save you money on your electrical bill.
