Abstract
A lamp assembly (10) has a base (12) with an axially extending post 14 having a first surface 16. The base and the post are thermally conductive. A light emitting diode (18) is operatively affixed to the first surface (16). A reflector (20) is in optical communication with the light emitting diode (18) and the reflector (20) is mechanically fixed to the base 12. Electrical connections (22, 24) extend through the base (12) to the light emitting diode (18).
Description
The cross reference of related application
This application requires on July 16th, 2004 submitted to, temporary patent application No.60/588,869 priority.
Technical field
The present invention relates to electric light, particularly relate to the electric light that utilizes single light emitting diode (following represent) light source with LED.More particularly, the present invention relates to have the electric light of led light source, this led light source is connected on the radiator with Fast Installation feature.
Background technology
In the past, most automotive luminaire has comprised the use of incandescent lamp.Although work well and very cheap, these bulbs have the short relatively life-span, and certainly, and employed thin filament is always owing to vibrate and suffer breakage.
Recently, some automobiles make articles for use (particularly stop light) be replaced by LED.These solid state light emitters have in 100000 hours zone and the fabulous life-span that can not produce vibration fault., these LED sources are hardwired into its suitable position, and this has just increased the cost of installing.In addition, this light source applications multiple LED, this has also increased cost.If this led light source can be configured to have the simplification of the installation of incandescent source, then so technically make progress.Alternatively, advantageously have and for good and all to install and without any need for the light source of concrete orientation.
Summary of the invention
Therefore, the objective of the invention is to eliminate shortcoming of the prior art.
Another object of the present invention is to strengthen the illumination operation.
These purposes are implemented by the lamp assembly in a scheme of the present invention, and this lamp assembly comprises: lamp holder, have the post that axially extends, and this post has first surface, the conduction of described lamp holder heat; Single light emitting diode operationally appends on the described first surface; Reflector is communicated with described light emitting diode (LED) light, and described reflector mechanically is fixed on the described heat conducting lamp holder; And electrical connector, extend through described lamp holder and arrive described light emitting diode.
Provide remarkable heat dissipation by light emitting diode being directly connected to heat conducting post, described post is the integral part of radiator lamp holder.And then by lamp holder and reflector are formed individual unit, so the quantity of part and therefore necessary assembly operation all reduce, thereby reduce the cost of lamp.
Description of drawings
Fig. 1 is the sketch of one embodiment of the present of invention; And
Fig. 2 is the similar view of an alternative embodiment of the present invention.
The specific embodiment
In order to understand the present invention in addition its other and further purpose, advantage and performance better, will be in conjunction with disclosure below the above-described referenced drawings and additional claim.
Now, the accompanying drawing with reference to having more details illustrates lamp assembly 10 in the drawings, and it comprises lamp holder 12, and lamp holder 12 has the post 14 that axially extends, and this post 14 has the first surface 16 on post 14 ends.This lamp holder and with it the post of one be heat conducting and preferably constitute by copper or aluminium.
Heat is conducted but the parts 19 of electric insulation can be affixed on the first surface 16 of post 14, and single light emitting diode 18 can operationally be appended on this insulating element 19 by for example heat conducting adhesive.In order to reach optimum efficiency, this light emitting diode is that the type diode is penetrated on the limit that axially centers on post 14.Reflector 20 and light emitting diode 18 optical communication, reflector 20 mechanically is fixed on the lamp holder 12.In a preferred embodiment of the invention, this mechanical fixation comprises and is embedded into reflector 20 and the lamp holder 12 that is molded together.Compare with the abundant mechanical strength that is provided, can provide fabulous waterproof sealing with embedding is molded.Alternatively, this mechanical fixation can comprise lamp holder 12 and the reflector 20 that is press-fitted in together.Back one method allows that reflector is installed in desirable position and light emitting diode is being embedded into after a while.
This post 14 can be a solid as shown in Figure 1, has the path that offers LED connecting line 22,24, and perhaps it can be the such tubulose of post 14a for example as shown in Figure 2.In one embodiment of back, first surface 16 can be on the stopper 16a on the end that is fixed to cylindrical column 14a.
Also have a kind of replacement scheme to allow that post 16 and lamp holder 12 are bonded to the suitable opening part of reflector.Under any circumstance, electrical connector 22,24 extends through lamp holder 12 arrival light emitting diodes by being insulated the ground threading by post 14.
At least one surface 30 of lamp holder 12 is exposed in the air to be used for heat dissipation along the outside of assembly 10.
In a preferred embodiment of the invention, this light emitting diode 18 is that the type diode is penetrated on the limit that axially centers on post 14 basically, to obtain maximum optics convenience.Such diode can obtain in open market.
Therefore, provide a kind of new lamp assembly, it conveniently is used to supply with the automotive lighting of various ways, for example taillight, stop light or signal for turn.This assembly is swung in fact freely and can be installed in many ways, and this provides very big flexibility.
Although illustrate and set forth the preferred embodiments of the present invention of considering at present herein, but should be appreciated that, under situation about not breaking away from by the additional determined scope of the present invention of claims, those of ordinary skills can carry out multiple modifications and changes.
