The invention provides an LED (Light Emitting Diode) cup bulb lamp, which is divided into a common lamp and a color adjustable lamp. The common lamp is used for replacing an existing halogen lamp cup bulb and the color adjustable lamp is used for color adjusting requirements of special equipment. The LED cup bulb lamp is composed of a heat dissipation bracket, a light reflection cup, lamp legs, a power supply board, an LED lamp body, heat dissipation fixed pieces, a fixed spring ring, heat dissipation holes and board inserting grooves, wherein the heat dissipation bracket is a metal hollow body; the plurality of heat dissipation holes are formed in a column body; the power supply board is arranged in the board inserting grooves in the column body; the front end of the heat dissipation bracket is connected with the LED lamp body, the middle part of the heat dissipation bracket is connected with the heat dissipation fixed pieces and the light reflection cup, and the back end of the heat dissipation bracket is connected with the lamp legs; the light reflection cup is mounted and fixed on the heat dissipation bracket; a cup opening of the light reflection cup is reversely folded towards the outer side to form a small platform; after one end of each heat dissipation fixed piece is fixed on the heat dissipation bracket, the whole heat dissipation fixed piece is tightly fitted with the outer surface of the light reflection cup, and the other end of the heat dissipation fixed piece is reinforced and fixed by using the fixed spring ring and the cup opening of the light reflection cup; the common lamp comprises two lamp legs and the color adjustable lamp comprises the plurality of lamp legs.
