Methods LED fluorescent tube to extend the life of the material
LED fluorescent tube high price is the popularization of disorder, price factors determine the price and price advantage, the lamp can make popular, is one of theimportant influence factor of traditional lamps and LED fluorescent tube replacement.
The actual thermal design is very simple, live in two directions:
1, the LED chip and the outer radiating element path shorter is better, the shorter thebetter you;
2, heat resistance, is must have the enough heat to the path must also have'radiating road enough'. This part of main structure for heat dissipation in cost, cost is not much.
LED chip technology, with the increase in the number of the large size waferfabrication process, will continue to reduce costs, reduce the speed of 20% annually in recent years, LED chip price factor, will light effects of ascension also included in the lower price, the same price to buy better products. LED chip to account for the proportion of 15% is still very reasonable, the future will continue to maintain at thislevel.
LED package cost accounts for a considerable proportion of the price, at about 50%,we have to select the LED package structure more appropriate. Cree, Lumileds,OSRAM existing packages are not in conformity with the lamp design, design cost willnot high. Bold design is the product design way, most of us still follow the copyinglarge company packaging structure thinking, innovation is too little, lack of confidence on their own innovation. COB is the future of lighting design mainstream, COB package according to the lighting optical requirements, while reducing the cost of the two optical design. Packaging costs in the total cost of lamp 20-30% is more reasonable.
The actual LED chip costs only 15%, other costs mainly to packaging, heat dissipation, cost, power structure. To lower the lamp cost from the cost composition issimple in manufacturing, LED chip reduction is not too big effect. Lamp manufacturingneeds the overall price reasonable, rational planning, comprehensive simply requirea certain part of cheap little, but we design the lamp architecture to economy, the most important is the optimization.
Heat cost must be maintained at 20%, 20% cost that is reasonable, the biggest problem is how to more innovation, more reasonable design. Structure design in lamppower is probably the weakest link LED fluorescent tubes, LED fluorescent lampdevelopment is seriously lagging behind, the quality to be improved. Design nowaccount for about 20% of the cost of LED fluorescent tube, some high. With the development of technology about 5-10% power in the most reasonable.
