Technical field
The utility model relates to car lamp device, and particularly, the utility model relates to a kind of car light light source fixture, and more specifically, the utility model relates to a kind of screw-type car light light source fixture.
Background technology
Existing car light light source fixed form is general to be welded on light source on the light source fixture earlier, then, and through the light source fixture fixedly realized the fixing of light source.
Fig. 1 is in the car light in the past, to the fixed form of fixing as the led light source of the light source of light guide media.Said fixed form comprises light guide media 1, support 2, light source 3, light source fixture 4 and screw 7.
In the past, at first that light guide media 1 is fixing with support 2 when car light being carried out the fixing assembling of light source, form the light guide media assembly.Then, light source 3 is welded on the light source fixture 4, forms light source assembly.Through screw 7 that the support 2 of light source assembly and light guide media assembly is fixing at last, to confirm the relative position of light source 3 and light guide media 1.That is, in the past technology is that light source assembly and light guide media assembly are formed the light source fixture.
Yet the defective that the said fixing mode exists is:
Because in the past technology is with light source assembly and light guide media assembly composition light source fixture, has multiple assembling, it is bigger to make the light of optical axis direction and the light guide media 1 in the light guide media assembly of the light source 3 in the light source assembly inject the error of perpendicularity of face.Thus, cause the light of light source 3 to inject direction generation deviation, make light often be difficult in light guide media 1, propagate according to the angle of designing requirement, thereby, light guide media 1 each position brightness disproportionation further caused again.
For example, light guide media 1 is bright partially near place, light source 3 positions, and far away from light source 3 positions local partially secretly, can not realize the design original intention of light guide media 1 uniformly light-emitting.
In addition; Because technology in the past is that light source assembly and light guide media assembly are formed the light source fixture; Have multiple assembling, the position deviation at center that the light of the centre of luminescence of light source 3 and light guide media 1 is injected face is bigger, makes light that light source 3 sends can not be fully inject face from the light of the end of light guide media 1 and injects; Cause light losing, cause the overall brightness of light guide media 1 dark partially.
The utility model content
For solving the defective of above-mentioned existence, the purpose of the utility model is: a kind of screw-type car light light source fixture is provided, and the location that can be used for the car light light source reaches fixing.Compare with the existing fixed mode, the screw-type light source fixture location of the utility model is more accurate, can improve the overall brightness and the uniformity of luminance of light guide media 1.
For achieving the above object, the utility model adopts following technical scheme:
A kind of screw-type car light light source fixture; Comprise light source assembly and the light guide media assembly that is connected with light source assembly; Said light source assembly comprises light source 3, light source fixture 4 and connects the connecting axle 6 of light source fixture 4; Said light guide media assembly comprises light guide media 1 and support 2, it is characterized in that
Said connecting axle 6 comprises light source stiff end 6a and light guide media stiff end 6b.
A kind of screw-type car light light source fixture according to the utility model is characterized in that said light guide media stiff end 6b is provided with the screw thread that cooperates with light guide media 1.
A kind of screw-type car light light source fixture according to the utility model is characterized in that, and is after said connecting axle 6 is located through alignment pin 6c with light source 3, fixing with light source fixture 4 through blanching rivet 5 again.
A kind of screw-type car light light source fixture according to the utility model is characterized in that, said blanching rivet 5 is through installing hole 6d on the connecting axle 6 and the rivet hole 4a on the light source fixture 4, and connecting axle and light source fixture 4 is fixing.
A kind of screw-type car light light source fixture according to the utility model is characterized in that, said light guide media assembly comprises light guide media 1 and the support of fixing with light guide media 12.
A kind of screw-type car light light source fixture according to the utility model is characterized in that, said light source assembly is connected fixing through the screw thread of the light guide media stiff end 6b of connecting axle 6 with the screw thread 1a of light guide media 1 head.
A kind of screw-type car light light source fixture according to the utility model is characterized in that, said light guide media 1 head is provided with the screw thread 1a that is used for light guide media stiff end 6b cooperation, and said light guide media 1 is photoconductive tube or lens.
According to a kind of screw-type car light light source fixture that the utility model provides, its beneficial effect is:
(1), reduced the rigging error of light source and light guide media, guarantee that better the light of optical axis direction and the light guide media of light source injects the perpendicularity of face.
(2), reduced the rigging error of light source and light guide media, the light that has improved light source luminescent center and light guide media is injected the position degree at the center of face.
