The utility model discloses a lens heat radiation mechanism. The lens heat radiation mechanism comprises a housing and a first heat radiation member. The first heat dissipation component is arranged in the shell, penetrates through the shell and is connected with a lens located outside the shell, and the first heat dissipation component receives heat conducted by the lens and can move relative tothe shell along with movement of the lens. On the basis, the utility model further discloses projection equipment comprising the lens heat dissipation mechanism. The utility model at least solves theproblem of heat radiation of the rear group of the lens during focusing of the lens. 本实用新型公开了一种镜头散热机构，包括：壳体和第一散热构件；所述第一散热构件设置于所述壳体的内部，穿过所述壳体与位于所述壳体的外部的镜头连接，所述第一散热构件接收所述述镜头传导的热量，且能够随所述镜头的移动而相对所述壳体移动。在此基础上，本实用新型还公开了一种包含所述镜头散热机构的投影设备。本实用新型至少解决了镜头调焦时镜头后群的散热问题。
