LED lighting fixtures to break through price barriers need to start with technology

[Zhongguancun Online B2B Display Channel] As far as domestic is concerned, it is expected that in the next 3 to 5 years, with the development of upstream chips, indoor lighting products account for 40% of semiconductor lighting applications.


● First, LED application products are difficult to dissipate heat


The structural design accounts for about 20% of the lamps and lanterns. The hardworking people in China have always been very low-priced, and the 20% cost is very reasonable. The biggest problem is how to be more innovative and more reasonable in design.


The cost of heat dissipation should be maintained at 5%. The actual heat dissipation design is very simple. It is used in two directions: First, the shorter the path between the LED chip and the external heat sink, the shorter the heat dissipation design. The second is the heat dissipation resistance. That is, there must be enough heat to pass through the path and there must be enough 'heat dissipation roads'. This part of the cost is mainly in the structure, and the cost for heat dissipation is not much.


● Second, the LED application power supply is weak


The power supply is the weakest link of LED lamps, and the development of LED lamps is seriously delayed, and the quality needs to be improved. The design now accounts for about 20% of the cost of the luminaire, which is somewhat high. With the development of technology, the power supply is probably 5-10% most reasonable.


The high cost of LEDs is actually compared with other current light sources. As the LED industry that invented blue LEDs in the 1990s, which led to the realization of LED white light, the current cost is not high. In particular, LED is environmentally friendly, energy-saving, and contains no mercury. Moreover, the price of LED lamps is declining every quarter. It is believed that it will reach a level acceptable to people in a short period of time.


● Third, domestic enterprises have no core technology


Most of the core patents in the upstream of the led industry are in the hands of foreigners. We don’t have the core technology. Although our LED application product manufacturing capacity accounts for 50% of the world and the share is 50%, the profit is the lowest. .


LED chips use a larger size wafer fabrication process with the increase of process and quantity, which will continuously reduce the cost. In recent years, the speed is reduced by 20% every year. In the price factor of LED chips, the improvement of light efficiency is also included in the price reduction. , the same price to buy a better product. The cost of LED lighting is mainly in the LED chip. As long as the price of the chip is lowered, the lumen price of the LED can be reduced to the equivalent of the current energy-saving lamp, and the indoor lighting will naturally bloom everywhere. LED chips also have a lot of room for price cuts.


Domestically, it is expected that in the next three to five years, with the development of upstream chips, indoor lighting products account for 40% of semiconductor lighting applications.
