Abstract: A panel light includes a light guide plate, L-typed frames and a light bar. The L-typed frames are connected with each other and surround edges of the light guide plate. Each of the L-typed frames includes a first board body, a second board body and a third board body. A gap is formed between the first and second board bodies. The third board body is connected between the first and second board bodies. An accommodating space is defined by the first, second and third board bodies. The edge of the light guide plate is inserted into the accommodating space between the first and second board bodies. The light bar is located on the third board body of one of the L-typed frames, and the light emitting direction of the light bar is toward a light incident surface of the light guide plate.

Abstract: The disclosure provides a light emitting diode projection bulb including a heat dissipation base, a light emitting diode module, and a annular heat dissipation member. The heat dissipation base includes a bottom surface, a sidewall surrounding the bottom surface, and a annular rim. The annular rim is connected to an end of the sidewall to define a first opening facing toward outside. A surface of the annular rim forms a plurality of first convection holes and a plurality of first locating portions. The light emitting diode module is installed on the bottom surface of the heat dissipation base and emits light toward the first opening. The annular heat dissipation member includes a second opening, a plurality of second convection holes, and a plurality of second locating portions.
