Description

Light-emitting diode lamp

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

As a highly efficient light source, the light-emitting diode has been widely used in various fields due to its environmental protection, power saving and long life.

The conventional light-emitting diode lamp includes a flat-plate heat sink and a plurality of light-emitting diode modules mounted on one side of the heat sink. When the light emitting diode is illuminated, the light emitting diode module mounted on the side of the heat sink functions as an illumination. Since the light-emitting diode is only mounted on the plane of one side of the heat sink, the light emitted by the light-emitting diode can only be radiated outward from the side plane of the heat sink at a small angle, and the illumination range is limited and the illumination effect is not good.

In view of this, it is necessary to provide a light-emitting diode lamp having a large irradiation range.

A light-emitting diode lamp includes a light stand and a plurality of light-emitting diode modules mounted on the light frame, the light-emitting diode modules are opposite to each other at an angle and from the middle to the opposite sides of the light stand The tilting arrangement is opposite to the angle between the two LED modules from the middle to the opposite sides of the lamp holder.

Compared with the prior art, the light-emitting diode modules of the light-emitting diode lamp of the present invention are oppositely disposed at an angle and are inclined from the middle of the light frame to opposite sides, and are opposite to the two light-emitting diode modules. The angle gradually increases from the middle of the lamp holder to the opposite sides, so that the light emitted by the LED module can be radiated to the periphery of the radiator, so that the illumination range of the LED lamp is wider.
