The present invention relates to an LED lighting device.

In general, a lighting device refers to a device that adjusts brightness by reflecting, refracting, or transmitting light of a light source and fixing or protecting the light source. Such lighting equipment may be classified into an indirect lighting apparatus, a semi-indirect lighting apparatus, a total diffusion lighting apparatus, a semi-direct lighting apparatus, and a direct lighting apparatus according to light distribution.

Recently, as countries around the world focus on green growth, an eco-friendly luminescent diode (LED) that saves energy is in the spotlight as a light source. LED has the advantages of low power consumption, long lifespan, and small size compared to existing light sources, and is widely used in LCD backlights, electric signs, fluorescent lamps, automobile brakes or turn signals, street lamps, various electronic product indicators, and flashing lights on ships and aircraft. is being utilized

LED lighting fixtures implemented with such LEDs have very good performance, but on the other hand, if the heat generated from the LED is not properly discharged, the LED or its driving circuit may deteriorate and the lifespan may be shortened.
