LED灯泡内通风及强制送风散热装置 Inner ventilation and forced air cooling device for LED bulbs

技术领域technical field

本发明属于电子技术领域，涉及一种LED灯的散热装置，尤其与一种实现泡内通风及强制送风的散热装置有关。The invention belongs to the field of electronic technology, and relates to a heat dissipation device for an LED lamp, in particular to a heat dissipation device for realizing ventilation and forced air supply in a bubble.

现有的LED灯中，一般包括灯头，灯体，灯罩。灯罩内设有LED发光单元，灯壳上或内部设有散热装置。这种结构LED灯的散热装置的缺点在于：其散热一般是设置在灯壳上或内部的散热片实现，只能实现灯壳部分的散热，由于LED光源的发热是360度的，光源前面的热主要集中在泡内。所以对泡内特别是光源部分的散热其实不太充分，不能使灯泡实现完全散热。由于大功率大角度LED球泡外泡为大过半球结构，使可以用于散热器的体积大幅减少，无法满足大功率大角度光照的LED灯具的使用。The existing LED lamps generally include a lamp base, a lamp body and a lampshade. An LED light-emitting unit is arranged inside the lampshade, and a heat dissipation device is arranged on or inside the lampshade. The disadvantage of the heat dissipation device of this structure LED lamp is that its heat dissipation is generally realized by the heat sink installed on the lamp housing or inside, and only the heat dissipation of the lamp housing part can be realized. Since the heat generation of the LED light source is 360 degrees, the front of the light source The heat is mainly concentrated in the bubble. Therefore, the heat dissipation of the bulb, especially the light source part, is actually not sufficient, and the bulb cannot be completely dissipated. Since the outer bulb of the high-power and large-angle LED bulb is larger than a hemispherical structure, the volume that can be used for the radiator is greatly reduced, and it cannot meet the use of LED lamps with high-power and large-angle illumination.
