Abstract: The present invention relates to a lamp. According to the present invention, the lamp comprises a PCB board and an integrated heat dissipation device. The PCB board is a double-sided PCB board suitable for mounting LED lamps on both sides and includes two heat dissipation edges installed to correspond to each other. The integrated heat dissipation device includes a radiator and two heat dissipation arms, the heat dissipation arms and the radiator are integrally molded using the same medium, and the two heat dissipation arms are bonded and assembled to the two heat dissipation edges, respectively. Accordingly, since the lamp is assembled by using a double-sided PCB board and the integrated heat dissipation device, the degree of integration between the PCB board and the radiator is increased and heat dissipation effect is effectively increased in comparison with a conventional method of assembling two PCB boards and a radiator. Since the integrated radiator reduces the number of heat conversions between different media and between different structures, heat conduction efficiency can be increased and the heat dissipation effect can be ensured well. Moreover, in comparison with the conventional method of combining two PCB boards, the double-sided PCB board does not require a separate intervening layer, such that thickness and the distance between the lamps of both front and rear sides are small, thereby being better matched with a light pattern of an original packing halogen lamp.
