Domestically, it is expected that the next 3-5 years, indoor lighting products accounted for 40% of the semiconductor lighting applications are very optimistic, with the development of the upstream chip.
â— an LED application product cooling is difficult
Would account for about 20 percent in the structural design of the lighting in industrious people will have been priced very low, 20% of the cost very reasonable, the biggest problem is how to be more innovative, the design is more reasonable.
Cooling costs to be maintained at 5%, the actual thermal design is very simple and protect the two directions: First, the LED chip and the external heat sink paths as short as possible, the shorter the better your thermal design; heat resistance is sufficient heat reached the path must also have sufficient cooling road. "This part of the cost structure is not much used in cooling costs.
â— Second, the weak power of LED application
Power is the weakest link led lamps, serious lag in the development of led lamps, quality needs to be improved. Design accounted for about 20% of the cost of lamps, some as high. As the technology development of power in about 5-10% of the most reasonable.
LED costs are high compared with other light, as in the 1990s before the invention of blue LED, the LED industry, leading to the white LED can be achieved, in fact, now the cost is not high. LED environmental protection, energy saving, no mercury, and every quarter of the price of LED lamps are sliding down, I believe we can achieve the acceptable level within a short period of time.
â— Third, the domestic enterprises, the core technology
led industry upstream, most of the core patent lies in the hands of foreigners, we do not grasp the core technology, although the manufacturing capacity of LED application products accounted for 50% of the global share to 50 percent, but profit is indeed one of the lowest .
LED chip with the process, increase in the number of larger wafer production process, will continue to reduce costs, reduce the rate of 20% annually in recent years, the price factor of the LED chip to light efficiency enhancement also included in the price reduction the same price to buy a better product. The cost of LED lighting in the LED chip, chip price down of LED lumens Price dropped of at this stage of energy-saving lamps, interior lighting, natural everywhere. LED chip is still a great room for price cuts.
Domestically, it is expected that the next 3-5 years, indoor lighting products accounted for 40% of the semiconductor lighting applications are very optimistic, with the development of the upstream chip.
