Abstract

See full text

LED lighting device includes LED light housing including hollow outer shell with planar mounting surface defined inner top side of accommodation chamber to face toward bottom opening and reflector cup mounted accommodation chamber and defining conical reflective surface therein and carrying lens at top center thereof with light exit surface of lens facing toward bottom opening of hollow outer shell, LED light-emitting module including circuit board mounted between planar mounting surface and lens, array of LEDs arranged front side of circuit board and control circuit with driver IC and capacitor thereof respectively arranged opposing front and back sides of circuit board for converting inputted AC power into stabilized DC power for driving LEDS. This structural design effectively increases available surface area of circuit board for circuit layout and related circuit layout insulation distance, allows installation of relatively larger amount of LEDs to increase overall brightness and makes reflector cup replaceable.
