Secret LED industry short board - structural design lags behind

LED high prices is the popularization of barriers, price factors price, lamp advantage and price can make popular, is one of the important factor to replace the traditional lamp LED lamps.

LED chip technology, with the growth in the number of the larger LED 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. LED chips accounted for 15% of the proportion is very reasonable, the future will continue to remain at this level.

LED package costs accounted for a considerable proportion of the price, at about 50%, we have to choose a more suitable package structure. Cree, Lumileds, OSRAM existing packaging are not in line with the design needs of lamps, design costs will be high. Bold innovative design is the product design outlet, most of us still continue to copy the packaging structure of large companies thinking, too little innovation, lack of confidence in their innovation. COB is the main way of future lighting design, according to the optical requirements of COB packaging, while reducing the cost of two optical design. Packaging costs in the total cost of lighting 20-30% is more reasonable.

Actual LED chip costs only 15%, other costs mainly to packaging, heat dissipation, cost, power structure. From the perspective of the cost of reducing the cost of lighting is in the manufacturing sector, simply require the LED chip is not too much to reduce the role of. Lamps and lanterns need to make the overall price is reasonable, reasonable planning, the overall requirements of a simple part of the little role of cheap, but we design the overall structure of the lamp to the economy, is the most important optimization.

Now accounts 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. The actual thermal design is very simple, following two directions: one is the LED chip and the LED heat sink path shorter is better, the shorter the better your thermal design; two, heat resistance, is to have enough heat to the path must also have enough heat 'road ". This part of the cost of the main in the structure, the cost is not much for cooling. Heat costs to be maintained at 20%, has been working hard for people in China will be very low pricing, the cost of the 20% think very reasonable, the biggest problem is how to more innovative, more reasonable design. The structure of the lamp in the design of the LED power supply is probably the weakest link in the LED lamp, seriously lagging behind the development of LED lamps, quality needs to be improved.

LED relative to other common sources, what are the advantages?

LED (light emitting diode) intrinsic characteristics determine has certain advantages.

Small size 1

LED is basically a small chip is encapsulated in epoxy resin, so it is very small, very light.

2 low power consumption

LED power consumption is very low, generally the working voltage of LED is 2-3.6V. Operating current is 0.02-0.03A. That is to say: it consumes no more than 0.1W.

3 long service life

In the right current and voltage, LED service life can reach 100 thousand hours.

4 high brightness, low heat

Heat radiation than HID or less of the incandescent lamp.

5 environmental protection

LED is made of nontoxicmaterialsas, unlike fluorescent lamps containing mercury pollution, while LED can also be recycled.

Durable 6

LED is completely encapsulated in epoxy resin inside it than light bulbs and fluorescent tubes are strong. There are no loose parts in the lamp, which makes LED can be said that it is not easy to damage.

7 strong controllability

Is easy to realize the color change of dark and light changes, and rapid response.
