Description

Light-emitting diode lamp

The invention relates to a lighting device, in particular to a light emitting diode lamp.

As a new generation of light source, the light-emitting diode light source can not replace the traditional incandescent lamp on a large scale. However, it has the advantages of long working life, energy saving and environmental protection, and is generally favored by the market. Moreover, the module composed of the light-emitting diode can generate a high-power, high-brightness light source, and thus will widely and revolutionarily replace the existing light source such as a conventional incandescent lamp, thereby becoming a main light source that meets the theme of energy conservation and environmental protection.

As the power and brightness of the LED or its module increase, the heat generated is also increased. If the heating problem of the LED is not properly solved, the working life of the LED lamp will be Seriously affected. Therefore, a heat sink that is in contact with the LED module is usually disposed in the lamp to dissipate heat from the LED module. However, the light-emitting diode module of the lamp is generally placed horizontally on one side of the heat sink to form a planar light source. Such a planar light source not only generates relatively concentrated heat, but also has a single illumination direction and a limited illumination area, and cannot be Uniform illumination is formed around the luminaire, which in many cases is difficult to satisfy the user.

In view of this, it is necessary to provide a light-emitting diode with uniform illumination. Lighting.
