A lamp includes a mounting frame, at least one supporting member, and a plurality of light emitting members. The mounting frame is provided with a connecting face. The supporting member is provided with a support portion and a connecting portion. The connecting portion of the supporting member is combined with the connecting face of the mounting frame. Each of the light emitting members is a light emitting diode (LED). Thus, the support portion of the supporting member has a convex arcuate shape to provide a wide-angle feature, and the light emitting members are arranged on the support portion of the supporting member in different angles and at different positions, so that the lighting angles of the light emitting members are complementary mutually to increase the whole lighting angle of the lamp.
