In related news, it is estimated that one hundred million 2011 LED chip supply by about 1,000, while the chip demand is about 89 billion, the oversupply ratio of 12%; 2012 in mainland China production capacity of the release of a large number of expected ove rsupply ratio will be expanded to 21%.
Although the chip supply, but the status of each product line, strong demand for ultra-high brightness LED, and less able to supply vendors, so the supply and demand is fairly stable. Mainland China, although out of production capacity, but mainly in the low-level application projects, such as indoor display, flashlight, fluorescent, and other products.
Compared with conventional light sources, LED lights than the energy-saving lamp energy saving of 80%. A spherical 5-watt home led light bulbs, you 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. Subject to the needs of the process, energy-saving lamp tubes containing heavy metals like mercury, once the tube is damaged, 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.
The biggest challenge in the current popularity of LED lighting is the 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. Has been hampered by the LED lighting products into the price of the general lighting field, is expected to be resolved within the next five years.
