Abstract
The present invention relates to main reflector and cooling system where a light source has been arranged in a main reflector and where cooling air is provided to the light source. The reflector and cooling system comprises a retro reflector arrange outside and facing the main reflector and the retro reflector comprises air inlets for providing cooling air towards the light source and air outlets for dissipating heated cooling air from the light source. The present invention relates also to a retro reflector for a reflector and cooling system.
Claims26
A lamp reflector and cooling system comprising:
- a light source arranged inside a main reflector, said main reflector reflecting a part of the light generated by said light source along an optical axis;
- a retro reflector arranged outside and facing said main reflector;
- said retro reflector having an exit aperture through which part of said light can pass;
- said retro reflector reflecting part of the light generated by said light source towards said main reflector, such that said main reflector then reflects the reflected light along said optical axis and through said exit aperture;
- a cooling apparatus to cool said light source, said cooling apparatus comprising a first blower;
- wherein said retro reflector comprises;
- an air inlet through which said first blower blows cooling air towards said light source;
- and
- an air outlet allowing said cooling air to flow out;
- and
- wherein said exit aperture is formed as two intersecting planes delimited by the retro reflector where the two intersecting planes are angled in relation to the optical axis.
A lamp reflector and cooling system comprising:
- a light source arranged inside a main reflector, said main reflector reflecting a part of the light generated by said light source along an optical axis;
- a retro reflector arranged outside and facing said main reflector;
- said retro reflector having an exit aperture through which part of said light can pass;
- said retro reflector reflecting part of the light generated by said light source towards said main reflector, such that said main reflector then reflects the reflected light along said optical axis and through said exit aperture;
- a cooling apparatus to cool said light source, said cooling apparatus comprising a first blower;
- and
- a separation plate having an aperture, wherein said retro reflector and/or said main reflector is arranged therein, said separation plate dividing a housing wherein said lamp reflector and cooling system is arranged into a first housing compartment and a second housing compartment;
- wherein said retro reflector comprises;
- an air inlet through which said first blower blows cooling air towards said light source;
- and
- an air outlet allowing said cooling air to flow out.
A retro reflector adapted to be arranged outside and facing a main reflector, where a light source is arranged inside said main reflector;
- said retro reflector having an exit aperture through which part of the light generated by said light source can pass;
- said retro reflector being adapted to reflect a part of the light generated by said light source towards said main reflector, such that said main reflector then reflects the reflected light through said exit aperture wherein said retro reflector comprises:
- an air inlet through which cooling air can be directed towards said light source;
- and
- an air outlet allowing said cooling air to flow out;
- and
- wherein said exit aperture is formed as two intersecting planes delimited by the retro reflector where the two intersecting planes are angled in relation to the optical axis.
