LONG-RANGE, HANDHELD SEARCHLIGHT |
摘要 |
A handheld searchlight for producing a high intensity beam of light output has an elongated housing including a handle portion for gripping by a user. A head has a window opening for transmitting a light beam. There is a mechanical coupling between the housing and the head. A parabolic reflector is mounted in the head facing the window and has an aperture for accommodating a high intensity lamp. The reflector has a longitudinal optical axis. The rotation of the head about the coupling causes movement of the parabolic reflector relative to the lamp along the optical axis thereby changing a spread of the high-intensity light beam. The searchlight further includes a rotatable bezel ring mounted on the head and a filter ring mount connected to the rotatable bezel. An optical filter is mounted in the filter ring mount.
