Abstract

The invention discloses a light emitting diode (LED) automobile high beam, which comprises a reflecting cup. The high beam is characterized in that: the reflecting cup comprises a first parabolic surface, a second parabolic surface, a third parabolic surface and a fourth parabolic surface; the first parabolic surface is connected with the fourth parabolic surface; the first parabolic surface is totally symmetrical with the third parabolic surface, the second parabolic surface and the fourth parabolic surface are restrained by the same parabolic surface equation, and the area of the fourth parabolic surface is greater than that of the second parabolic surface; and the focal points of all the parabolic surfaces are superposed, an LED luminous source group is arranged at the focal points, and the LED luminous source group is fixed on an LED installation base. By adopting the automobile high beam, the emergent light spot is a rectangular light spot at the same time of ensuring that the emergent light is parallel light, and dizziness of the high beam and irradiation on human eyes are furthest reduced.

Description

LED dazzle light tool
Technical field
The present invention is the light fixture invention, is specifically related to shine the distance light light fixture before the LED automobile.
Background technology
Along with growth in the living standard, the consumer goods that automobile has begun to become a kind of masses enter huge numbers of families, for automobile industry is brought huge business opportunity and tempting prospect.And the automobile ornaments particularly concern the head lamp system that automotive safety moves, and as an important step on the automobile making industrial chain, bring a large amount of market opportunities also will for relevant enterprise.Present auto lamp market is mainly occupied by Halogen lamp LED and xenon lamp.LED relies in recent years good development trend and self numerous advantage in car headlamp market preliminary application and development to be arranged, has had many brands to release the LED car light of oneself on the market such as automobile at present and obtains good effect.
Summary of the invention
The objective of the invention is to the good characteristic of LED is given full play on car headlamp, solve the dazzling luminous of orthodox car light fixture when overcoming LED calorifics key issue, provide to have the LED dazzle light of emission indirectly.
The technical solution used in the present invention is:
A kind of LED dazzle light tool comprises reflector, and reflector comprises the first parabola face, the second parabola face, the 3rd parabola face and the 4th parabola face that joins successively; The first parabola face also joins with the 4th parabola face; The first parabola face and the 3rd parabola face be symmetry fully, and the second parabola face and the 4th parabola face are retrained by same parabola face equation, and the area of the 4th parabola face is greater than the area of the second parabola face; The focus of all parabola faces overlaps, and at this focus place LED light emitting source group is set, and LED light emitting source group is fixed on the LED mounting seat.
Further, LED light emitting source group is made up of four great power LEDs.
Further, the LED mounting seat outside is provided with the claw type heat-dissipating casing.
Further, the LED mounting seat is provided with aluminium base, and LED light emitting source bond pads is on aluminium base.
Adopt dazzle light tool of the present invention, when can guarantee that emergent light is directional light, the outgoing hot spot is a rectangular light spot, reduces the dazzling problem of light fixture to the full extent and to the radiation of human eye.The area of the 4th parabola face of reflector and the area of the second parabola face more greatly, making has more light reflection than large tracts of land one side, light fixture emergent light shape of spot reaches best, illumination reach best effect simultaneously the curved surface formed of the front end of two parabola faces meet the curve shape of car headlamp module, for supporting existing car light advantage is comparatively easily arranged.
The present invention is by LED mounting seat and claw type heat-dissipating casing excellent contact and the enough area of dissipations of claw type heat-dissipating casing, the heat that makes LED produce conducts rapidly and is lost in the air by heat-dissipating casing, has well solved the hang-up that present puzzlement LED uses at car headlamp.
The reflector that adopts 4 LEDs and double-paraboloid line to retrain matches and guarantees that light is concentrated, and the outgoing directional light produces rectangular light spot, solves the dazzling influence of light preferably, and after light reflected through reflector, the light that sends was parallel rays, is shaped as rectangular light spot.The heat-dissipating casing that on the outside of reflector and LED mounting seat, adds enough area of dissipations, guarantee the enough radiating requirements of great power LED, be welded on the abundant contact and the heat-conducting glue preferably of the aluminium base of reflector bottom by LED, good the heat conduction and the enough area of dissipations of scale that dispel the heat fully guarantee advantages such as LED long service life and light efficiency height.
Automobile mounted power supply is voltage stabilizing 12-15V output, and the present invention adopts constant voltage-constant current conversion electric power for LED provides constant-current supply output, guarantees the operate as normal of LED, gives full play to the LED advantage, reaches the advantageous effect of using the LED auto lamp.Simultaneously in the selection of LED, the present invention is according to going out the higher better LED of actual conditions selection heat radiation of temperature because position and car engine principle concern car headlamp, heat as early as possible, to the greatest extent many lost assurance LED operate as normal and use, satisfy the requirement of LED to temperature.
The present invention's advantage compared with prior art: utilize parabola face reflector to go out light characteristic, light fixture sends the directional light with rectangular light spot; Adopt the claw type radiator structure, guarantee heat as early as possible, many to the greatest extent lost the time, guaranteed that LED normally uses, given full play to the advantage of LED, reach the original intention that is applied in the auto lamp lighting field.The application that this invents alternative traditional Halogen lamp LED and HID xenon lamp has the effect of launching rectangular light spot, solves the difficult problem of LED dazzle, can produce in a large number.
