A LED reflector lamp (100) comprises a control circuit; at least two LED light sources (60) controlled by the control circuit; at least two light source panels (20), on which the LED light sources (60) are mounted respectively; at least one heat conductive plate (10), the light source panels (20) are thermally conductive fixed on and connected with the at least one heat conductive plate (10), respectively; a reflector cup (30) having a reflector inner surface (32), an opening formed by edge of the reflector inner surface (32), and a groove (34) formed on the bottom of the reflector cup (30); and a heat dissipater (50), in which a cavity is provided, the size and shape of the cavity are designed to combine with at least one part of the reflector cup (30) and the heat conductive plate (10). Wherein the heat conductive plate (10) fixed on and connected with the LED light sources (60) and the light source panels (20) is inserted into the groove provided on the bottom of the reflector cup (30), so that the LED light sources (60) are parallel to the central perpendicular axis of the reflector cup (30). |
