| 摘要 |
The invention provides an environmental shroud (490, 590) and a camera assembly (40, 50) including such environmental shroud (490, 590) which absorbs and dissipates heat energy that is not reflected and/or deflected from radiation and heat energy that is generated by the contents of the camera housing so that the camera housing temperature does not exceed the maximum rated temperature. In one embodiment, the camera assembly (40) includes a camera housing (430) which has a mounting cap (440) attached to sidewalls (426) to which is attached an optical surface (135). The camera housing encloses a camera system. An environmental shroud (490) is attached to the camera housing and includes a plurality of vertical strips (441,445) situated concentrically with the camera housing (430) and with each other with gaps being present between the vertical strips (441, 445) and between the camera housing (430). In another embodiment, the environmental shroud is a turbine and includes a plurality of vertical blades (506) situated concentrically with the camera housing (530), whereby wind which contacts the blades causes the shroud to rotate and generate a centrifugal force effective to remove moisture from the camera housing (530).
