[0047] The heat dissipation cylinder 310 includes a base plate 312, and a plurality of heat dissipation fins 313 are arranged parallel to each other on the outer surface of the base plate 312. The inner surface of the base plate 312 is provided with blind holes for receiving fastening screws 319 to lock and thus fix the light source board 318 on the base plate 312.

[0048] Please continue reading. Figure 4 and Figure 5 This application embodiment also provides a reflector cup 340, which is used to be installed in the heat dissipation cylinder 310 of the vehicle lamp 300.
