LED Chip Price Cuts
With the the sapphire capacity expansion, the price drop white led light bulbs last year prices have been in decline. Some experts expect the whole of 2012 the price of led bulbs will be decreased by 20% to 30% over 2011, which will give the corporate earnings tremendous pressure. The life of the LED industry: only through technological innovation, improve product cost, in order to ward off risks and enhance their competitiveness.
There is no doubt that, LED bulbs prices is beneficial to the development of the industry, which will accelerate the popularization of led lighting applications. However, the decline in prices, will bring a chain reaction of many aspects, such as the cost of doing business will be increasing pressure, profit margins will be smaller and smaller. Not only of upstream materials enterprises would be subject to cost and profit pressure, the whole industry chain, including chip companies, packaging companies, downstream fixture manufacturers will be subject to varying degrees of impact.
Price decline in the development of any industry will have to face the reality, which is conducive to the development of the industry, LED adverse, only the prices in order to expand the scope of applications to the LED into the tens of thousands of households . But for the production enterprises, the need to continue to develop new products, reduce manufacturing costs, enhance the rate of qualified products in response to the downward pressure on prices.
Recent price decline of LED bulbs do 5W (about 450lm), 8W (about 800lm) LED bulb overall than last year, a decrease of about 60%, the price of each link are, but for the lighting, the key per thousand lumens prices, improved chip performance, lower prices for LED bulbs played an important role, the last year for the led bulb 10 x 23 chip about 7lm, can now to 8 ~ 8.5lm same production 5W led bulb lamp, the original 65 to 70 chips, there are now 50 to 55 chips can meet the original brightness ; addition, 10 x 16 chip can reach 7lm So, if 10 x 16 chip instead of the original 10 x 23 chip can achieve the same brightness, Bulb price down naturally.
Upstream chip companies, of course, also faces the risk of price cuts, chip companies only continue to improve product performance, enhance lm / W value, so that you can meet the same brightness needs to reduce costs, improve product competitiveness.
LED chip price decline is an inevitable trend, the 2011 price cut in more than 40%, it is expected that the 2012 price cuts of 15% to 25%. The price decline is the trend of the times, as described above, to improve product performance, reduce production costs is the only way out of the upstream enterprises to respond to the price decline.
More enterprises will be to protect against the risk of the industry through technological innovation. The wave of Huaguang also innovative, the pursuit of technological progress, "reverse polarity red LED is the selection Innovation and Technology Award. In the chip sector enterprises such as Japan, Korea, Europe and the United States has a very strong strength, compared to the Chinese chip enterprises and foreign enterprises gap.
Red LED, reverse polarity, we developed a new product, used for lighting and display field, our technical level close to the international advanced level, can replace imported products, but also to break the monopoly of foreign products.
LED industry abroad earlier compared to the domestic development, and the overall technical level better than domestic enterprises. However, with the international technical exchanges and closer cooperation, more frequent flow of talent, the domestic technology level and international gap is gradually narrowing.
Some domestic production of red, yellow, light technology also has the shadow of our products and, therefore, has a unique understanding of the material system products and advantages. Also the earliest to do the reverse polarity red LED enterprises, the level of product technology walk in the forefront of the domestic counterparts, can replace imported products.
Reverse polarity red LED innovation is the use of chip process reversed, so that the production of the chip structure conducive to the light-emitting and improve the structure of the brightness. The LED epitaxial wafer set LED reflector technology, the coarsening process and the current expansion process in a greatly improved external quantum efficiency of the chip. In particular is the use of a unique current expansion technology, so that the external quantum efficiency of the chip increased by 10%. Chip PN junction down, allows for heat dissipation, improve the life of the chip.
