COMBINED PROJECTOR Russian patent published in 2013 - IPC F21S8/00 

FIELD: electricity.

SUBSTANCE: projector includes emitter (2) of visible light, which are arranged in housing (1), protective glass (3), reflector (4), light screen (5) and optic filter (6) installed coaxially to the projector emitting axis and enveloping visible light emitter (2). Optic filter (6) is equipped with at least one section with a bandpass coordinated with the range of working frequencies of the emission receiver operating together with the projector. Position of optic filter (6) relative to visible light emitter (2) is changed remotely by means of movement assembly (7) equipped with a filter position control unit.

EFFECT: arrangement of an optic filter inside a projector housing provides for quick switching of emission from Visible Light mode to infra-red radiation and vice versa with possibility of adjustment of visible light brightness and has no influence on aerodynamic properties of the projector and its vibration rigidity.
