A heat sink (24) is fixed to the second surface (20) and preferably is an inherent part thereof to insure good heat conductivity between the post (16) and the heat sink (24). Circuitry (26), which can be mounted on a printed circuit board, is associated with the LED light source (22) for supplying power thereto. Suitable electrical connections, not shown, can be supplied from the circuit ry (26) to the LED light source (22) via insulated wires running up the side of the post (16) or threaded through longitudinal apertures formed in the post (16). Alternatively, an electrically insulating material supplied with conductive traces can cover the post (16). The LED light source can include a cap having a secondary reflector thereon or the light source (22) can be covered by a dome-shaped, transparent element having sidewalls a nd a closed top having at least one metallized surface and including an optic.

Description

The header assembly that is used for light-emitting diode
Technical field
The application requires in the priority of the temporary patent application No.60/588470 of submission on July 16th, 2004.
The present invention relates to light source, be specifically related to adopt the light source of light-emitting diode (LED), relate more specifically to be used for the light source of automotive field such as headlight, taillight, stop lamp, fog lamp, direction indicator lamp etc.More specifically, the present invention relates to can be packed to realize this light source of industrialization.
Background technology
In the past, most of automotive luminaire can relate to the use incandescent lamp bulb.Although work is good and relatively cheaply, these bulbs have the short life-span, used thin filament always can be because of the vibration easy fracture certainly.
In recent years, some application, particularly stop lamp are replaced by LED.These solid state light emitters have mysterious about 100,000 hours useful life, and are not easy to lose efficacy because of vibration.Yet these led light sources are connected its suitable position by rigid line, and this has increased installation cost.Therefore, provide led light source if the simplification of incandescent source can be installed, this can be a progress in present technique field so.
If adopt the led light source of single-piece LED to be used, this light source can provide acceptable illuminance, good heat radiation and ease simultaneously, and then this also is another progress in present technique field.
Summary of the invention
Therefore, an object of the present invention is to overcome shortcoming of the prior art.
Another object of the present invention is to improve led light source.
In one aspect of the invention, these purposes realize by a kind of lamp assembly with the reflector that is used for direct light on direction initialization is provided.Reflector has the heat conduction supporting column that is arranged in hole wherein and is assemblied in the hole.This pillar has first of being positioned at reflector and is positioned at second of the reflector outside.The LED sideward emitting light source of single-piece is fixed on first, and radiator is fixed on second, and circuit is associated with led light source to be used to it that electric energy is provided.
In one embodiment of the invention, light source comprises having the top cover of establishing second reflector thereon, and in another embodiment of the present invention, light source comprises dome-shaped Transparent Parts, the closure tip that it has sidewall and comprises at least one metallization face.In transparent component, can comprise the optics that is designed to have specific luminous pattern.
Description of drawings
Fig. 1 is the schematic cross sectional views of one embodiment of the present of invention; With
Fig. 2 is the schematic cutaway view of the part of an alternative.
Embodiment
In order to understand the present invention and other and further purpose, advantage and performance better, below with reference to following discloses content and the claims that combine above-mentioned accompanying drawing.
Specifically referring to accompanying drawing, shown a kind of lamp assembly 10 in Fig. 1 now, it comprises the reflector 12 that is used for direct light on direction initialization.In reflector its roughly place, bottom formed hole 14, and heat conduction supporting column 16 is installed in the hole 14 and has second 20 that is positioned at first 18 within the reflector and is positioned at the reflector outside.Pillar 16 is preferably metal such as copper.But the LED sideward emitting light source 22 of single-piece preferably by electric insulation but the parts 23 of heat conduction be fixed on first 18.Radiator 24 is fixed on second 20 and is preferably its intrinsic part, to guarantee the thermal conductive resin between pillar 16 and radiator 24.The circuit 26 that can be installed on the printed circuit board (PCB) is associated so that for it provides electric energy with led light source 22, and is preferably mounted at the outside of reflector.Can be by along pillar 16 sides or pass the insulated conductor that is formed at the vertical hole in the pillar 16, the unshowned suitable electrical connection on 22 is provided from circuit 26 to led light source.Perhaps, the electrical insulating material that has a conductive trace can cover on the pillar 16.
Light source 22 can be installed on the top of pillar 16 individually, and perhaps it can have top cover 28, and top cover 28 comprises second reflector 30 mounted thereto.When top cover 28 was in place, led light source can directly emit beam to reflector 12 on ground as shown in arrow 60 during operation, and perhaps light can send and be redirected towards reflector 12 towards second reflector 30, as arrow 62 schematically shown in.
As alternative, led light source 22 can be had sidewall 34 and be comprised that the cheese Transparent Parts 32 of the closure tip 36 of at least one metallization face 38 covers.Sidewall 34 can comprise at least one optics 40, and it can be designed to the form of the integrally molded lens that specific luminous pattern is provided.
Pillar 16 has the preseting length that records along longitudinal axis 42, makes led light source 22 be positioned on the focus point of reflector 12.
Reflector 12 can be any required shape, but is preferably spill as the automobile tail light assembly time.More specifically, this shape can have parabola shaped cross section.
Therefore a kind of led light source that is applicable to the single-piece of automobile tail light assembly just is provided, and it is installed easily and has a good heat-sinking capability.The illumination effect that can adopt other optics to obtain customizing.
Although shown and introduced the current the preferred embodiments of the present invention that are regarded as, yet it will be apparent to those skilled in that, under the prerequisite of the scope of the present invention that does not break away from claims and limited, can carry out variations and modifications the present invention.
