Abstract
A lighting assembly and its method of manufacture. The lighting assembly has a heat sink. A plurality of surfaces are disposed on the front of the heat sink. At least one first surface is oriented in a first plane and at least one second surface is oriented in a second plane. A first plurality of light sources are mounted to at least one first surface. A second plurality of light sources are mounted to at least one second surface. As a consequence, light can be directed in two distinct directions to create a discernable high beam condition and low beam condition. A space is defined in front of the light sources. At least one heat exchange element is provided that protrudes forward from a heat sink into the space thereby helping to vaporize any condensation that may form within that space.
Claims16
A lighting assembly, comprising:
- a heat sink having a front and a rear, wherein a plurality of surfaces are disposed on said front of said heat sink, wherein said plurality of surfaces include at least one first surface that is oriented in a first plane and at least one second surface that is oriented in a second plane;
- a first plurality of light sources mounted to said at least one first surface, wherein said first plurality of light sources emit light at a perpendicular to said at least one first surface;
- a second plurality of light sources mounted to said at least one second surface, wherein said second plurality of light sources emit light at a perpendicular to said at least one second surface;
- a transparent protective cover, wherein a space exists between said front of said heat sink and said transparent protective cover;
- and
- at least one heat exchange element that protrudes forward from said heat sink into said space between said heat sink and said transparent protective cover.
A headlight assembly for a vehicle, comprising:
- a heat sink having a front and a rear;
- light sources positioned on said front of said heat sink, wherein said heat sink absorbs heat generated by said light sources;
- a protective cover disposed over said light sources, wherein a space is defined between said protective cover and said light sources;
- and
- at least one heat exchange element protruding forward from said heat sink into said space between said light sources and said protective cover, wherein said at least one heat exchange element exchanges heat with said space.
A method of producing a headlight assembly having a high beam condition and a low beam condition, said method comprising the steps of:
- providing a heat sink having a front and a rear, wherein a plurality of surfaces are disposed on said front of said heat sink, said plurality of surfaces including at least one first surface that is oriented in a first plane and at least one second surface that is oriented in a second plane;
- mounting a first plurality of light sources to said at least one first surface, wherein said first plurality of light sources emit light at a perpendicular to said at least one first surface, creating said low beam condition;
- and
- mounting a second plurality of light sources to said at least one second surface, wherein said second plurality of light sources emit light at a perpendicular to said at least one second surface creating said high beam condition.
