PURPOSE: An LED light with a cooling fan is provided to secure the reliability of a product under high temperature by controlling the RPM of a fan through a PWM method. CONSTITUTION: An anti-glare sheet and a light spreading plate are arranged inside a lens(10). The lens protects an LED circuit board(20). A conductor(30) supplies the power of the power supply unit to the LED circuit board. A heat plate(50) is assembled with the LED circuit board. A cooling fan(70) is installed in the heat plate. A main body forms the outline of the LED lighting device. A socket connection part is connected to an external socket. |
