Description

A lamp heat dissipation structure

technical field

The utility model relates to the technical field of lighting devices, in particular to a heat dissipation structure of a lamp which is applied to a lamp with a light-emitting diode as a light source and can achieve improved waste heat discharge efficiency.

Background technique

At present, due to the requirement of high brightness for lamps, most of them use high-power, large-size lighting sources, such as incandescent bulbs, mercury lamps and other illuminants, but the lighting efficiency is poor, which causes serious power consumption. At a time when energy is increasingly scarce and precious, it is not a temporary choice. Moreover, when a high-power, large-size lighting source is used, the heat generated is difficult to dissipate from the housing, resulting in excessive temperature of the housing or burning of the lighting source, requiring frequent maintenance and replacement, wasting manpower, material resources and time.

Applications such as car lights, outdoor lighting, and situational lighting have become the focus of global attention.

However, when LEDs are currently used for lighting purposes, high-power LEDs are usually used as light sources because lamps require high light illuminance. Higher light has been obtained by applying a higher current to the LEDs. Illumination; however, while the brightness and illuminance of the light increase, the heat generated by it inevitably increases. If the heat generated is not discharged in a timely manner, it will not only easily cause heat accumulation around the LED, but also reduce the luminous efficiency and cause light decay, and may directly affect the life of the LED.
