Abstract
A lamp includes a bowl shaped reflector having an elongated aperture in its base for mounting a light source. A light source including a filament enclosed in a transparent envelope is mounted in the aperture such that when the light source is illuminated light is projected from the front of the reflector and also escapes through the aperture to the rear of the reflector. A lamp housing extending behind the reflector is transparent and includes a color filter material. Light projected from the front of the reflector provides light for illumination, while light escaping through the aperture in the reflector is transmitted through the color filter material and provides a safety signal.
Claims19
A lamp, comprising:
- a bowl-shaped reflector, said reflector having a concave reflective front surface a back surface and an apex;
- said reflector having an aperture extending therethrough at the apex thereof for mounting a light-source therein;
- a housing enclosing said back surface of said reflector, at least a portion of said housing being transparent and including a color filter material;
- a light-source mounted in said aperture, said light-source including a filament enclosed in a transparent envelope;
- and
- said transparent envelope having a filament portion thereof extending beyond said front surface into said reflector and a neck portion thereof extending through said aperture beyond said back surface of said reflector, whereby a first portion of light from said incandescent light-source may escape via said neck portion of said transparent envelope through said aperture into said housing for illuminating said color filter material, thereby providing a color safety signal.
A lamp, comprising:
- a bowl-shaped molded glass reflector, said reflector including a concave front surface having a reflective coating thereon, a back surface, an apex, a light-source mounting portion extending from said back surface at the apex of said reflector, and an elongated rectangular aperture extending through said front surface and through said light-source mounting portion;
- a housing enclosing said back surface of said reflector and said light-source mounting portion of said reflector, at least a portion of said housing being transparent and including a color filter material;
- an incandescent light-source mounted in said aperture, said light source including a filament enclosed in a transparent envelope, said envelope having a filament portion and a neck portion;
- and
- said filament portion extending beyond said first surface into said reflector, said neck portion extending through said aperture into said light-source mounting portion and attached thereto, and said neck portion arranged in said rectangular aperture to define an open space between said transparent envelope and said reflector whereby a first portion of light from said light-source escapes via said neck portion of said transparent envelope through said aperture into said housing, and a second portion of light from said light source escapes via said open space through said aperture into said housing, said escaping light for illuminating said color filter material, thereby providing a colored safety signal.
