Three issues after the LED lamp price bottleneck

Introduction: heat dissipation cost should be maintained at 5%, the actual thermal design is very simple, following two directions: one is the LED chip and the external heat sink path shorter is better, the shorter the thermal design your better; two, the heat resistance is to have enough heat to heat the road path must also have enough "".

It is reported that currently the biggest problem restricting the promotion of LED lighting is the price of LED lights, energy-saving lamps to face several times, consumers are often the second, although the LED lamp price continues to decline, but still far from acceptable to consumers so far.

LED lamp price bottlenecks mainly in three aspects

Three issues after the LED lamp price bottleneck

First, LED application cooling

Structural design in the light of about 20%, has been China's labor pricing will be very low, the cost of the 20% is very reasonable, the biggest problem is how to be more innovative, more reasonable design. The cost of cooling must be maintained at 5%, the actual thermal design is very simple, following two directions: one is the LED chip and the external heat sink path shorter is better, the shorter the thermal design your better; two, the heat resistance is to have enough heat to heat the road path must also have enough "". This part of the cost is mainly in the structure, not much for the cost of heat.

Two, LED application power weak

Power supply is the weakest link of LED lamps, seriously lagging behind the development of LED lamps, the quality needs to be improved. Now account for about 20% of the cost of lighting design, some high. With the development of power technology in 5-10% is probably the most reasonable. LED high cost, in fact, is the current relative to other light sources, as was invented in 1990s Blu ray LED, which led to the realization of LED white light LED industry, in fact, the cost is not high.

Three, enterprise core technology

Most of the upstream LED industry's core patent master in foreign hands, we do not grasp the core technology, although we LED applications in the global manufacturing capacity accounted for 50%, accounted for 50%, but the profit is indeed the lowest ring. LED chip technology, with the growth of a larger size wafer fabrication process, will continue to reduce costs, reduce the rate of 20% annually in recent years, LED chip price factor, will enhance the optical efficiency is also included in the lower price, the same price to buy better products. The cost of LED lighting is mainly in the LED chip, as long as the chip prices down, LED lumen unit price can be reduced to the equivalent of the current energy-saving lamps, indoor lighting naturally everywhere.
