Problems solved by technology

However, the heat energy generated by LED lights is small when they are working, and the temperature at the light source is low. When encountering heavy wind and snow, the snow cannot be melted, and the situation of freezing is often caused by the accumulation of water vapor between the LEDs, which makes the road surface unable to be cleared. Enough lighting, even the signal of traffic lights becomes unclear, and even lead to traffic accidents

Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] Please refer to figure 1 and figure 2 , is the LED lighting device of the first embodiment of the present invention, which includes an LED lighting assembly 20, a heat sink 70 thermally combined with the LED lighting assembly 20, a joint 80 electrically connected to the LED lighting assembly 20, and the LED lighting assembly 20. The LED lighting assembly 20 is connected with a temperature sensor 30 and a power driver 60 for providing electric energy to the LED lighting assembly 20 .

[0034] The radiator 70 is cylindrical. The cylindrical side surface 72 of the cylindrical radiator 70 is provided with a thread 74 extending around its axis. The thread 74 makes the radiator 70 have a larger heat dissipation surface, which is beneficial to the dissipation of heat. The radiator 70 is made of materials with high thermal conductivity, su...

Abstract

The invention provides a light emitting diode (LED) device. The device comprises an LED module and a power driver used for providing electricity to the LED module, wherein the LED module comprises visible LED chips and infrared LED chips. The device also comprises a temperature sensor, wherein the temperature sensor is used for sensing the temperature of the surface of the LED module; and when the temperature of the surface of the LED module, which is sensed by the temperature sensor, is lower than 0, the temperature sensor sends a control signal to the power driver to control the power driver to output current to the infrared LED chips so that the infrared LED chips emit infrared light to melt ice on the surface of the LED module.

Description

technical field [0001] The invention relates to an LED lighting device. Background technique [0002] Lamps using light emitting diodes (Light Emitting Diode, LED) as light sources consume 90% less energy than traditional incandescent lamps, which is energy-saving and environmentally friendly. In order to save energy and electricity, many cities have switched to LED lights for traffic lights and street lights. However, the heat energy generated by LED lights is small when they are working, and the temperature at the light source is low. When encountering heavy wind and snow, the snow cannot be melted, and the situation of freezing is often caused by the accumulation of water vapor between the LEDs, which makes the road surface unable to be cleared. With enough lighting, even the signal of the traffic lights becomes unclear, which may even lead to traffic accidents. Contents of the invention [0003] In view of this, it is necessary to provide an LED lighting device capab...
