Abstract
A lamp (10) has a reflector (12) arrayed about an axis (14). The reflector has a circumferential rim (16) and an LED light source (18) that is mounted upon a support (20). The support can be arrayed along the circumferential rim (16) or mounted directly to the concave reflector (12).
Description
Technical field
The application requires in the priority of the temporary patent application No.60/588143 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, brake lamp, fog lamp, steering indicating light etc.
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 are replaced by LED.These solid state light emitters have mysterious about 100,000 hours service life, and are not easy to lose efficacy because of vibration.The concrete example of various schemes is in U.S. Patent No. 6641287; No.5136483; No.6474852; No.6672741; No.6238073; No.5471371; Shown in No.6840652 and the No.6585402.Although feasible solution is provided, yet these lamps are produced more complicated and costliness, and require the LED mounting structure or the alignment procedure of difficulty.If LED illumination can extend to other field of automotive lighting, if particularly can suitably control luminous being used for special-purpose, and if installation procedure is simple, relatively more cheap and use easily, this will be a progress in present technique field so.
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.
Another object of the present invention is to improve the combination of led light source and reflector.
These purposes are achieved in one aspect of the invention; Include around the axis setting and have the spill reflector of circumferential rim by providing; And be installed in support member that this spill reflector is associated on led light source, this support member guides light along this circumferential rim setting and towards this spill reflector.
A kind of lamp is provided in alternative, it comprises the spill reflector that centers on the axis setting and have circumferential rim, and be installed in support member that this spill reflector is associated on led light source, this support member has the end that is fixed on the described spill reflector.
These lamps provide the fairly simple structure of easy aligning.
Description of drawings
Fig. 1 is the schematic diagram of one embodiment of the present of invention;
Fig. 2 is the schematic diagram of an alternative of the present invention;
Fig. 3 is the schematic diagram of another one embodiment of the present invention; With
Fig. 4 is the schematic diagram of another embodiment of the present invention.
The specific 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 10 in Fig. 1 now, it comprises the spill reflector 12 that is provided with and has circumferential rim 16 around axis 14.Led light source 18 is installed on the support member 20 that is associated with spill reflector 12, and support member 20 has leg 22, and it for example is fixed in the spill reflector 12 by the interference fit of leg 22 in notch 22a.Led light source 18 can be any suitable pattern such as LED sideward emitting, and the color of the light that is sent can be suitable for the purposes of lamp, and for example, the ruddiness that sends can be used for taillight or brake lamp, and white light can be used for headlight.As required, can adopt more than one LED.If only adopted a LED, then it is preferably aimed at along axis 14.
Shown an alternative in Fig. 2, wherein support member 20 is for having the U-shaped of sweep 24 and leg 22,26.Led light source 18 with can be directly towards the mode of spill reflector 12 guiding light and be installed in the sweep 24 of U-shaped support member, the leg 22 of U-shaped support member, 26 are fixed in the described spill reflector 12 in any suitable manner, for example by pressing fit among notch 22a and the 26a.
In Fig. 3, lamp 10 comprises the spill reflector 12 that is provided with and has circumferential rim 16 around axis 14 similarly.Yet in this case, led light source 18 is installed on the V-arrangement support member 20a that is associated with spill reflector 12 by being provided with along circumferential rim, and wherein led light source 18 is from the edge but not guide light from the center towards the spill reflector.
Circumferentially rim 16 has the groove 28 of installation, and it can or can be series of openings for the form of V-shaped groove shown in Figure 3, has only shown such opening in Fig. 4.V-shaped groove can be circumferentially continuous, perhaps can form one or more locus of discontinuities, and this depends on the number of LED to be used.Groove 28 is provided with support member fixator 30, and it can be the form of stretching out flange 30a shown in Figure 3.In this case, V-arrangement support member 20a can have initial structure 20b, and can be pressed into and be snap-fitted in the shell.As alternative, can provide angled 30b shown in Figure 4.
But support member 20 heat conduction to be dissipating the work calories of LED, and can be provided with the necessary circuit 32 of operating light (schematically illustrated) in selected environment.
In the time of on being installed in rim 16 or near it, led light source 18 is mounted to can be with respect to axis 14 angled θ to guarantee correct aligning.Although this angle can depend on the curvature of reflector and specific LED to be used certainly, yet, be used for the typical par reflecting device that automobile is used therein, the angles of about 30 degree guide at the light with LED 18 that this can provide good effect on the one hand on the surface of reflector 12.
Therefore, LED 18 is distributed in widely on the reflector rim and the radiating effect that improves is provided, and simultaneously the light that is sent is concentrated on the reflector.Center at reflector does not form the hole, therefore can not form shade or gap in the beam pattern of gained.The assembling of snap fit formula has guaranteed the correct location of LED.
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.
