How to improve the heat dissipation function of LED high bay light?
The lifetime of LED high bay light, a most depends on the heat dissipation function of lamps and lanterns, heat dissipation function is one of the LED high bay light popularization obstacles.Want to improve the service life of lamps and lanterns, improve heat dissipation function is chosen, so how to improve heat dissipation function?
1, reduce the thermal resistance of LED device, adopts the new encapsulation structure, new technology, selection good thermal conductivity, good heat resistance, new materials, include metal adhesive materials, fluorescent powder mixed glue, etc., the thermal resistance below 10 ℃ / W or lower.
2, reduce the heat, LED high bay light use the heat dissipation material with good thermal conductivity as far as possible, good vent way on the design requirements, make the heat spread out as soon as possible, for temperature should be less than 30 ℃.In addition, improve the level of modular the heat dissipation of lamps and lanterns should be referred to the agenda.
3, from the LED chip, to take the new structure, new technology, improve the LED chip junction temperature, heat resistance, heat resistance, and other materials, for the cooling requirements reduced.
4, there are a number of ways for heat dissipation, the effect is very good also, such as using heat pipe.Using heat pipe, however, will cause the increase of production cost, sales price of LED high bay light is also naturally to increase, limit part of the consumer. Therefore, at the time of improve the heat dissipation function of LED high bay light, need to consider its price, if can do the production cost is not high, the cooling function has good effect, that is the best.
