Description of drawings
Fig. 1 is the exploded perspective view of the embodiment of the invention;
Fig. 2 is the partial section along the line 2-2 among Fig. 1;
Fig. 3 is the partial section along the line 3-3 among Fig. 1.
The specific embodiment
In order to understand the present invention and other and further purpose, advantage and performance better, in conjunction with following content of above-mentioned description of drawings and claims.
Referring now to more detailed accompanying drawing, Fig. 1 shows LED lamp 10, and it can be a fog lamp for example, comprises the housing 12 with inwall 14, and inwall 14 defines cavity 16, and cavity 16 provides the opening of face forward " F ", and cavity 16 has back wall 18.Preferably by the radiating piece 20 that extends on the outside portion 22 that is included in back wall 18 such as the so suitable metal housing 12 of aluminium.
In order to assemble enough light, three-dimensional collimating optics device needs very near light source 26.The transparent material that holds out against 150 ℃ automotive environment only has glass, and this material has the limitation in the design, causes some optical plans not realize.And this material expensive.
In order to eliminate these shortcomings, provide the compound projection lens that forms by plastics.Thereby these lens 38 are connected to housing 12 and seal circuit board 24, led light source 26 and reflector 28.Lens 38 are enough far away so that allow to use plastic material from light source 26, and lens 38 have the first light refraction element 40 and the second light refraction element 44, wherein the first light refraction element 40 is a plurality of forms that groove lens 40a is arranged around outer peripheral edges 42 arrangements, and the second light refraction element 44 is the form that is positioned at the concave-convex lens 44a at lens 38 centers.This part of lens makes led light source 26 direct imagings.That is,, it makes the light level expansion thereby making the light vertical focusing obtain high strength.This needs concavo-convex configuration, unless because just standard projection lens only can obtain big extended corner several millimeters the time apart from light source, and apart from light source only several millimeters can produce heat problem.Because of big focal length and required minor diameter, nearly half light that is produced can miss lens.In order to retrieve these light, above-mentioned reflector is provided, this reflector is caught and is calibrated this light and makes the outside or the outer peripheral portion that comprises vertical channel 40a in its scioptics.These grooves 40a flatly expands light.
Optionally over cap 46 is across on lens 38, and for example is fixed in housing 12 by recessed connector 60, and this recessed connector 60 is outstanding and engage protuberances 62 on the housing 12 from covering 46.
Be formed for holding the plug-type coupling 50 of current supply line on the outside portion 22 of housing 12, this current supply line is connected to the electric power of vehicle power supply circuit board 24 and is connected to led light source by circuit board 24.
At work, the first light refraction element of arranging around the outer peripheral edges 42 of lens 38 40 is intercepted and captured by the light of led light source 26 emissions and from the light of reflector 28 to front-reflection.The light that the first light refraction element will be intercepted and captured is guided into and is centered close to or the subhorizontal first level band.The second light refraction element 44 is positioned at lens 38 centers and intercepts and captures the light of directly launching forward from led light source 26, and the light that this quilt is intercepted and captured is guided to the second level band that is overlapped in the first level band.
Therefore, a kind of small-sized independent fog lamp is provided, and this fog lamp obtains good photo-equilibrium by compound lens, and wherein said compound lens has core and Outboard Sections, this core is used for projection, and this Outboard Sections is used for from reflector and the light expansion that collimated through vertical channel.Lens can be made by glass or plastic material, however preferred plastics.Form particular beam figure by revising optics appearance (optical presentation), this structure also is suitable for other purposes, for example near or distance light, back-up lamp or the common lighting use of using as headlamp.
Although illustrated and described the content that is considered to the preferred embodiments of the present invention at present, yet obviously can do various changes and modifications at this does not break away from the scope of the invention that is defined by the following claims for a person skilled in the art.
