Pivot holes are formed in the ear posts on the two sides of the middle part 400 and used for connecting pivot shafts. The intermediate member 400 defines the space required for pivoting. In the case where the pivot shaft is connected to the pivot hole of the middle member 400, the pivot shaft leaves a heat dissipation space 400a with the middle member 400. The pivot shaft may be made of a heat conductive member (e.g., made of an aluminum alloy) and is fixedly connected to the back surface of the lamp body to absorb heat generated in the lamp body 100 and then radiate and/or conduct heat to the heat dissipation space 400a, thereby enhancing heat dissipation of the lamp body 100 and preventing overheating of the lamp body 100. Alternatively, the lamp body 100 is connected to the middle member 400 by a pivot shaft in such a manner that the heat dissipation structure (e.g., heat dissipation holes, heat dissipation fins, etc.) thereof faces the middle member 400. That is, the back surface of the lamp body 100 is provided with heat dissipation holes and/or heat dissipation fins, which are all directed toward the middle part 400.
