2011 by the application of the terminal market weak demand, prices have begun to produce knock-on effect down the LED\\ s. According to relevant reports, in 2011 the overall output of the LED industry, no significant increase, estimated 2 011 LED chip supply by about 100 billion stars, but chip demand is about 89 billion, the oversupply ratio of 12%; 2012 production capacity in the mainland The massive release expected oversupply ratio will be expanded to 21%. The majority of people in the industry consider the civilian market, it should be things in 2015. Look forward to the era of LED lighting \"civilian price\".
Although the chip supply, but the status of each product line is different, four yuan LED needs a good, high brightness LED demand is very strong, and able to supply the manufacturers is relatively small, so the supply and demand is fairly stable. As for the part of the blue LED, the demand is relatively poor, mainly because of poor demand for TV backlight, but the lighting market demand for metric stud is pretty good. Mainland China, although out of production capacity, but mainly in the low-level application projects, such as indoor display, flashlight, fluorescent, and other products.
As for the consumption of the LED die a huge number of TV backlighting markets, by the slow pace of economic recovery affect global LEDTV shipped as expected. Most TV brands to the tune of the LED backlit TV penetration from 70% in the beginning of the year dropped by 50 percent this year, the total LCD TV shipments by 220 million audience raised to 203 million units, so that the LCD TV LED quantity only been 175 one hundred million, the output value of only $ 1.67 billion, revised down as much as 26%.
Compared with conventional light sources, LED lights than the energy-saving lamp energy saving of 80%. It is understood that a 5-watt home led spherical bulb can replace a 11-watt energy-saving lamps, a 90-watt LED street lighting effect is equivalent to a 250-watt high pressure sodium lamp. Energy-saving lamp with its lower power consumption, longer life, better light efficiency performance, the application of 9-volt battery clip, replace the traditional incandescent lamp. But not well known, subject to the process requires energy-saving lamp tubes containing heavy metals like mercury, once the lamp is broken, the mercury into the environment, the environment and cause harm to humans. LED lights unlike the energy-saving lamps and mercury pollution, does not pollute the soil and groundwater, in line with the concept of energy saving and environmental protection.
The LED light source has the advantages of long life, 25,000 hours, the light fades, the brightness can still reach the traditional light efficiency of the new lamp. And household LED lamps flicker, no radiation, lead-free, mercury-free. LED lighting to open civilian market, the biggest obstacle is that it is higher than the people at affordable prices. Epistar Corporation assistant general manager Wang Xiwei layer has said: the biggest challenge in the current popularity of LED lighting is price pressure, followed by units of lumens per watt. From the chip to all aspects of the package, you must take a variety of measures, such as adding a red crystalline powder, and the development of high-voltage LED, in order to achieve the purpose of reducing costs. Predicted that high-voltage LED will gradually become the mainstream market, 75W and 100W lighting alternatives will also be center stage. Plastic battery box is also widely used, has been hampered by the price of LED ligh ting products to enter the general lighting field, is expected to be resolved within the next five years.
