Light emitting diode (LED) lamp capable of timing and provided with radiating device

Abstract

The invention relates to a light emitting diode (LED) lamp capable of timing and provided with a radiating device. The LED lamp capable of timing and provided with the radiating device solves the problems that radiating performance is bad in the prior art, an angle of emergent light of an LED cannot be adjusted effectively, and an LED light source cannot be controlled to turn off automatically under the condition of overheating. The lamp comprises a housing and an LED light source arranged at one side of the housing. The other side of the LED light source is provided with the radiating device, and a color changing device is arranged at one side, close to the LED light source, of a light source cover. The LED light source is connected with a light spot control device, and a connecting device is arranged at one side, far from the LED light source, of the housing. The radiating device comprises three radiating parts which respectively are a rectangular tooth radiating part, an arc tooth radiating part and an irregular surface radiating part. The color changing device is a plurality of transparent crystals which are arranged in a spiral mode, and the housing is provided with a timing device. The lamp has the advantages of being strong in radiating capability and high in radiating efficiency. The lamp controls the LED light source to turn off automatically under the condition of overheating.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to a timeable LED lamp with a cooling device. Background technique [0002] The application of LED lighting sources in road lighting is mainly the application of LED street lights or tunnel lights. The existing LED street lights or tunnel lights have a lamppost, and a lamp holder is installed on the upper end of the lamppost. The LED light distribution module is set inside. A common LED light distribution module has a substrate on which one or more LED chips are packaged, and a lens is placed in front of the LED chip, and the light emitted by the LED chip is refracted to the road surface after passing through the lens. [0003] If there is no secondary optical design, the light emitted by the LED chip will project a circular spot on the ground, and some of the light will always shine on the road shoulder, sidewalk or landscape next to the driveway, resulting in waste of light and light ...
