PURPOSE: An LED lamp is provided to quickly radiate heat by adjusting a ventilation area according to the internal temperature of a lamp. CONSTITUTION: An LED lamp comprises a case(10), cover(20), an LED substrate(30), a duct(40), and an opening control unit. The cover opens or closes the opening of the case. The LED substrate is applied with power for lighting. The duct induces the heat generated from the LED substrate to a heat dissipation hole in the case. The opening control unit includes an opening control board(50), a first discharge hole(51), and a second discharge hole(52). The opening control board is mounted inside of the case to be capable of reciprocating translatory motions. [Reference numerals] (80) Controller |
