Description
Technical field
The present invention relates to a kind of side and throw total reflection LED car lamp.
Background technology
Existing guide structure car light, because placing LED at light pipe two, utilizing light pipe total reflection principle guide-lighting, make photoconduction center and two brightness irregularities, and light utilization efficiency only having about 20%-30%, more cannot realize point-like light belt and the high effect of utilization rate.Therefore, urgently existing guide structure is improved, to realize uniform in light emission and the high light pipe effect of utilization rate, to replace conventional light guide pipe; Also point-like light belt can be realized and the high effect of utilization rate.Go for different lamp kinds and different vehicle demands.
Summary of the invention
The object of the invention is to solve the uneven and problem that light utilization efficiency is not high of guide structure bright dipping in prior art, provide a kind of side to throw total reflection LED car lamp.The present invention designs side and throws total reflection LED car lamp, comprise lamp body, total reflection lens, LED module, it is characterized in that: LED module to be arranged in lamp body light-emitting area level upwards, in lamp body, total reflection lens is installed, the light-emitting area of LED module is positioned at total reflection lens and enters on the vertical plane in light face, total reflection lens enters light face for several lens, the cross section of total reflection lens is total reflection right angled triangle, hypotenuse is fully reflecting surface, total reflection lens exiting surface is densely covered fly's-eye lens, on LED module, the corresponding total reflection lens of each LED enters lens in light face.The total reflection lens lens entered on light face are Fresnel Lenses or collector lens.Fly's-eye lens on total reflection lens exiting surface is matrix arrangement.LED in the light-emitting area of LED module is matrix arrangement.Advantage of the present invention is uniform in light emission and the high effect of utilization rate, also can realize point-like light belt and the high effect of utilization rate.Can guide structure be substituted and be applicable to different lamp kinds and different vehicle demands.

Detailed description of the invention
In figure, total reflection LED car lamp is thrown in side, comprise lamp body (not drawing in figure), total reflection lens 1, LED module 2, it is characterized in that: LED module to be arranged in lamp body light-emitting area level upwards, in lamp body, total reflection lens is installed, the light-emitting area of LED module is positioned at total reflection lens and enters on the vertical plane in light face 3, total reflection lens enters light face for several lens, the cross section of total reflection lens is total reflection right angled triangle, hypotenuse 4 is fully reflecting surface, total reflection lens exiting surface 5 is the fly's-eye lens 6 gathered, on LED module, the corresponding total reflection lens of each LED7 enters lens in light face.The total reflection lens lens entered on light face are Fresnel Lenses 8 or collector lens 9.Fly's-eye lens on total reflection lens exiting surface is matrix arrangement.LED in the light-emitting area of LED module is matrix arrangement.
During use, when two LEDs neighbor distance are far away, namely when the LED position of the light-emitting area of LED module is in raw bits, each Fresnel lens structure (concentrator lens structure) and the LED position one_to_one corresponding of total reflection lens lower surface, the spacing of adjacent two Fresnel Lenses (concentrator lens structure) is pulled open, and Fresnel lens structure (concentrator lens structure) has optically focused effect herein, light comparatively disperses, little intersection, the light that single LEDs sends forms single hot spot, and the light entirety that car light finally penetrates is rendered as some point-like light and is arranged in lamp bar.
When two LEDs close together, light is adjacent two LEDs light cross-distribution after Fresnel lens structure (concentrator lens structure), after the fly's-eye lens refraction on total reflection lens exiting surface, the light entirety that car light finally penetrates presents even strip-shaped.
Luminosity uniformity test
1, tester: enlightening Bean Science and Technology Ltd. _ GPM-A200 type light distribution machine.
2, test condition: 1. darkroom;
2. light-receiving device distance: 3.16m.
3. 20 LEDs
3, test specification: 45L ~ 45R; 15U ~ 15D
4, regulation is tested: ECE R87
5, test data:
6, when two LEDs distances are very near, light is after Fresnel lens structure (concentrator lens structure), and the light that adjacent LED sends is interlaced with each other, and staggered light reflects through fly's-eye lens, and spreading out of uniform light, reaches uniform effect.
7, above test result display, test zone does not have dark space and excess region, shows that this side head total reflection structure bright dipping is evenly distributed.
Light utilization efficiency is tested
1, tester: distant place integrating sphere.
2, test condition: LED does not add total reflection lens and LED adds total reflection lens.
3, test specification: 360 degree of solid angles.
4, test data:
5, light enter Fresnel lens structure (concentrator lens structure) afterwards light gathered, light input end light loss is reduced.By the light gathered through total reflection lens, the light injecting fully reflecting surface is all reflected, and improves light utilization efficiency.
6, above test result display, adding lens light flux is 115.6lm, not adding lens light flux is 144.2lm, to add after lens luminous flux attenuation 28.6lm, overall transmitance is 80.16%, and from light transmittance tester measurement result, total reflection lens light transmittance is 0.8478, known, light utilization efficiency is 0.946.
In the general guide structure car light that market is common, light pipe light utilization efficiency is 20%-30%.This guide structure is conventional light guide tubular construction photoconduction light utilization efficiency height at least 60% comparatively.
