Description
Technical field
The utility model relates to automobile lamp technical field, be specifically related to a kind of can content with funtion requirement, save cost, and whole aperture light intensity evenly light guide structure.
Background technology
In automotive trim air-conditioner controller, multimedia, often require aperture scheme dazzle effect to strengthen.To realize the existing routine of described function be at present following organization plan: Fig. 1 is existing light guide structure schematic diagram, shown in Figure 1, is welded with four LEDs 2 lamps, has light guide ring 1 above at PCB 3 plate.Practical function is when pcb board being connected electricity, four LEDs 2 are luminous together, by direct light through light guide ring 1. due to direct light stronger, the easy like this region having LED 2 below, when people sees that visible light is strong especially, and the light intensity in region between LED is just more weak, creates non-uniform phenomenon, the quantity of LED 2 must be increased like this, cost is significantly increased.
Utility model content
The technical problems to be solved in the utility model is for the problem existing for prior art and provides a kind of cost-saving structure.Because light is linearly propagated in uniform dielectric of the same race, simultaneously according to the principle of light reflection when light is when propagating into different material, interface change the direction of propagation return again in original material.As long as in fact people sees that light is even, not high to the requirement of strength of light, be unfavorable for safe driving if too high.For this reason by the structure of light guide ring, to the direct light of LED after multiple reflections, make whole aperture uniform intensity.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of light guide structure, described light guide structure comprises lamp socket, plug-in unit LED and lightguide, lightguide is inserted on pcb board by the some positioning bars bottom lightguide, plug-in unit LED200 is fixed on lamp socket, lightguide comprises lightguide main body and at an angle two the guide-lighting axles intersected of cylindrical shape, the infall of two guide-lighting axles intersected is light entrance port, the light entrance port of the guide-lighting axle of the optical registration sent of plug-in unit LED, to be upturned an angle away from the bottom surface of light entrance port in the bottom of lightguide main body.
In preferred embodiment of the present utility model, the quantitative range of positioning bar is 2-6, is evenly distributed on the bottom of the circumference of the lightguide main body of cylindrical shape.
In preferred embodiment of the present utility model, the quantity of positioning bar is 3.
In preferred embodiment of the present utility model, the angular range between two guide-lighting axles intersected is 80-100 degree.
In preferred embodiment of the present utility model, the angle between two guide-lighting axles intersected is 91 degree.
In preferred embodiment of the present utility model, the angular range tilted in the bottom of lightguide main body is 5-30 degree.
In preferred embodiment of the present utility model, the angle tilted in the bottom of lightguide main body is 10 degree.
Positive progressive effect of the present utility model is: the light guide structure that the utility model provides has the following advantages: the utility model is with only adopting a LEDs organization plan just energy content with funtion requirement, and conventional scheme adopts four LEDs organization plans, save cost, and whole aperture uniform intensity, improve the competitiveness of product in market.

Detailed description of the invention
The utility model preferred embodiment is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
The light guide structure schematic diagram that Fig. 2 provides for the utility model, the light guide structure assembling schematic diagram that Fig. 3 provides for the utility model, as Figure 2-3, the utility model comprises lamp socket 100, plug-in unit LED200 and lightguide 400, lightguide 400 is inserted on pcb board 300 by the some positioning bars bottom lightguide 400, plug-in unit LED200 is fixed on lamp socket 100, lightguide 400 comprises lightguide main body 401 and at an angle two the guide-lighting axles 402 intersected of cylindrical shape, the infall of two guide-lighting axles 402 intersected is light entrance port 403, the light entrance port 403 of the guide-lighting axle 402 of the optical registration sent of plug-in unit LED200, to be upturned an angle away from the bottom surface of light entrance port 403 in the bottom of lightguide main body 401.
The quantitative range of positioning bar is 2-6, is preferably 3, is evenly distributed on the bottom of the circumference of the lightguide main body 401 of cylindrical shape.
Angular range between two guide-lighting axles 402 intersected is 80-100 degree, generally can elect 91 degree as.
The angular range tilted in the bottom of lightguide main body 401 is 5-30 degree, is preferably 10 degree.
Plug-in unit LED200 is by being inserted in lamp socket 100 (as Fig. 3) after frock bending 90 °, and finally insert on pcb board 300, and be welded on pcb board 300, its assembly structure is simple.
In the signal of Fig. 2, the angle between two guide-lighting axles 402 intersected is 91 degree.The light that LED200 launches is by lightguide 400, and after there is repeatedly refraction, uniform aperture is formed on bottom, one at least partially through lightguide bottom reflection on surperficial aperture, due to after repeatedly refraction, at the light intensity decreasing of bottom.For this reason bottom increase protrude step 404 (tilting an angle, Fig. 4), to strengthen reflection angle, light be mapped to protrusion step 404 the gradient on back reflection diffraction efficiency higher.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall within the scope of claimed the utility model, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
