Description

A kind of LED headlights

Technical field

The utility model belongs to automobile technical field, more particularly to a kind of LED headlights.

Background technology

Traditional car headlamp mainly has 2 kinds, and a kind of is the halogen bulb of industry universal, and another is gas discharge Lamp, such as xenon headlight.The filament rapid wear of halogen headlamp, short life frequently switches on easy burn-out.The startup electricity of Xenon headlamp Pressure, electric current are high, and drive circuit works scope is wide, difficulty is big, fault rate is high.LED headlamps have energy-conservation, long lifespan, green ring Protect, without stroboscopic, impact resistance, low-heat operating at voltages, wide-voltage range, luminous efficiency height, brightness height, fast response, aobvious finger height, face Color reductibility is good, weatherability and the advantages of good reliability, it is just progressively replaced traditional car headlamp, as vehicle front lighting The development trend of lamp.LED headlamps are loaded into the housing of automobile front face, because the receiving space of this housing is limited, by LED Headlamp is loaded into limited spatial dimension, it is necessary to consider the luminous efficiency problem of LED headlamps simultaneously and in high power Heat dissipation problem under working condition.Do not have the problem of a kind of LED can preferably solve radiating currently on the market, simultaneously LED driving needs to be connected with LED with electric wire and plug, very cumbersome, and sealing can be deteriorated more because of the change of joint, The light illumination mode of LED headlights only has dipped beam and distance light both of which, it is impossible to more accurate regulation.Therefore a kind of LED headlights are needed, With preferable heat sinking function LED can be protected to be influenceed from high temperature, one can be integrated into driver, while can adjust The distance between lens are so as to realize the switching of nearly far lamp.

Utility model content

The purpose of this utility model is to provide a kind of LED headlights, it is intended at least solve technology present in prior art One of problem.

The utility model is adopted the technical scheme that to solve technical problem present in known technology：A kind of LED is big Lamp, including bottom plate, it is characterised in that：The upper surface of the bottom plate is provided with stepper motor, vertical shaft, integral type driver and cylinder, Fixed plate is fixedly connected with the cylinder, the lower surface of the fixed plate is provided with blower module, the upper surface of the fixed plate Provided with pedestal and mounting head, it is provided with the mounting head on LED illuminators, the periphery of the pedestal and reflection shield is installed, The top of the cylinder is provided with the second lens, and the stepper motor is connected with leading screw, the leading screw and silk by step motor shaft Thick stick set is used cooperatively, and the periphery upper ring cap of the vertical shaft has axle sleeve, and the top of the axle sleeve and screw set is fixed with the second circle Cylinder, second cylinder ring is enclosed on the periphery of first cylinder, and the top of second cylinder is provided with the first lens.

Further, the blower module includes fan and filter mantle, and the filter mantle is provided with filter bores, the filter bores Size be outwards to become big successively along the center of filter mantle.

Further, the integral type driver includes constant-current supply and temperature inductor, and the integral type driver passes through Electric wire is electrically connected with blower module and LED illuminator respectively.

Further, the structure of the mounting head is triangular prism shaped, and one is fitted with each side of the mounting head The individual LED illuminator.

The utility model has the advantages and positive effects of：The utility model integrated level is higher, reduces electric wire connection, It can protect LED pipe will not be because electric current is excessive and burns up with preferable heat sinking function, integral type driver.Mistake on filter mantle The size variation in filter opening hole is right against the trend that fan is gradually decreased from edge to middle position wind speed, is not influenceing fan cooling While can also reduce dust and enter fan, the mode that the position for employing the first lens can be certain come adjust the first lens with The distance between second lens, so that the distance of LED irradiation changes, the adjustable range of distance is more accurate.
