Abstract (en)
An LED lamp includes a heatsink housing (4), a heatsink plate (2) mounted on the heatsink housing, an LED module (1) mounted on the heatsink plate, and a circuit board (3) mounted in the heatsink housing and electrically connected to the LED module. Thus, when the LED module is operated, the heat produced by the LED module is transferred by a heat conduction of the heatsink plate and by a heat convection between the heatsink plate and the heatsink housing, so that the heat produced by the LED module is carried away exactly and quickly, thereby enhancing the heat dissipation effect of the LED module.
