The power supply is the weakest link in highlighting the LED light, which seriously lags behind the development of LED lighting 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 technical development power is about 5-10% the most reasonable.
The high cost of LED, in fact, is relative to other current light sources, as the invention of blue LED in the 1990s, which led to the realization of high brightness LED fill light industry, the cost of its implementation is not high. In particular, LED environmental protection, energy saving, mercury-free, and the price of LED lamps and lanterns are falling every quarter, I believe we can reach people's acceptable level in a short period of time. The structural design accounts for about 20% of the lamps. The biggest problem is how to be more innovative and design more reasonable. The heat dissipation cost must be maintained at 5%. The actual heat dissipation design is very simple. Take two directions: First, the shorter the path between the LED chip and the external heat sink, the better. The shorter the heat dissipation design, the better. Second, the heat dissipation resistance. That is, there must be enough cooling to reach the path and at the same time, there must be enough "cooling paths." This part of the cost is mainly in the structure, not much for cooling costs.
In the LED chip price factor, the improvement of light efficiency is also included in the price reduction, and the better product is purchased at the same price. The cost of LED lighting fixtures is mainly in the LED chip, as long as the chip prices down, LED lumen unit price can be reduced to the current stage of energy-saving lamps, indoor lighting will naturally bloom everywhere. LED chips also have much room for price cuts.
