Abstract
A vehicle lamp assembly includes a housing and an LED lamp carried in the housing. A signal mirror includes a mirror and an LED lamp. The LED lamp includes a heat extraction member.
Claims53
A mirror assembly, comprising:
- a mirror including a reflective surface;
- and
- a lamp positioned adjacent the mirror, said lamp including an emitter and a lens, the lens having a peak intensity optical axis offset from the center of the emitter whereby light produced by the emitter is emitted from the lens at an angle that is a function of the offset.
A signal mirror, comprising:
- a transparent housing defining an interior volume;
- at least one lamp carried within the interior volume of the housing to project light through the transparent housing;
- and
- a mirror positioned within the housing.
1 more element
A vehicle lamp assembly, comprising:
- a housing;
- and
- at least one LED lamp carried in the housing, the at least one LED lamp comprising at least one LED chip in thermal communication with a heat extraction member, wherein said heat extraction member comprises a lower thermal resistance than a thermal resistance of LED lamp electrical connections, wherein said at least one LED lamp is capable of operating continuously at greater than approximately 100 mW.
A signal mirror, comprising:
- a mirror;
- at least one first high power LED lamp, at least one second high power LED lamp and at least one third high power LED lamp;
- each high power LED lamp including a heat extraction member, at least one emitter carried on the heat extraction member, and two or more electrical leads having a thermal resistance higher than the heat extraction member electrically coupled to the emitter, and wherein each LED lamp is positioned adjacent the mirror to produce visible light;
- and
- said at least one first high power LED lamp being configured as a turn signal, said at least one second high power LED lamp being configured as a puddle light and said at least one third high power LED lamp being configured as a keyhole illuminator.
2 more elements
An apparatus, comprising:
- at least one lamp comprising a heat extraction member, said heat extraction member comprising a lower thermal resistance than lamp electrical connections;
- and
- a mounting plate in contact with said heat extraction member, wherein said
- mounting plate is a passive heat sink.
