一种散热快的防水型塑包铝LED球泡灯A waterproof plastic-clad aluminum LED bulb lamp with fast heat dissipation

技术领域technical field

本实用新型涉及灯具领域,特别是一种散热快的防水型塑包铝LED球泡灯。The utility model relates to the field of lamps, in particular to a waterproof plastic-clad aluminum LED bulb lamp with fast heat dissipation.

背景技术Background technique

随着科技日益高速的发展，大功率发光二极管High Power LED作为装饰与照明光源得到不断进步与广泛应用，大功率发光二极管是洁净绿色环保光源，越来越被人们所重视和接受，目前光源类产品主要用于家居照明，商业店铺装饰等地方的照明。然而，由于大功率发光二极管的芯片及驱动电源本身在工作时会产生大量的热，如果这些热量不及时地导走散发出去，对其性能及寿命会造成很大的影响。目前的LED球泡灯，一种是直接将灯壳做成带散热槽的金属散热器，以通过灯壳来散热，这种结构尽管散热效果好，但是生产成本高，且产品不防水；另一种是将灯壳做成由塑料外壳和铝内壳组成的塑包铝结构，然后再在塑料外壳上开设散热孔，这种结构的泡灯，尽管降低了生产成本，但是热传递性能不好，驱动板容易发热，影响LED球泡灯的使用寿命，而且容易进蚊虫和灰尘。另外产品仍存在不防水的问题。With the rapid development of science and technology, high-power light-emitting diode High Power LED has been continuously improved and widely used as a decorative and lighting source. The products are mainly used for lighting in home lighting, commercial shop decoration and other places. However, since the chip of the high-power light-emitting diode and the driving power supply itself will generate a lot of heat during operation, if the heat is not conducted and dissipated in time, its performance and life will be greatly affected. One of the current LED bulb lamps is to directly make the lamp housing into a metal radiator with a heat sink to dissipate heat through the lamp housing. Although this structure has a good heat dissipation effect, the production cost is high, and the product is not waterproof; One is to make the lamp housing into a plastic-clad aluminum structure composed of a plastic outer shell and an aluminum inner shell, and then open cooling holes on the plastic outer shell. Although the bulb lamp with this structure reduces the production cost, its heat transfer performance is not good. Well, the driver board is prone to heat, which affects the service life of the LED bulb, and is prone to mosquitoes and dust. In addition, the product still has the problem of not being waterproof.
