Abstract
The invention discloses an LED headlamp for a motor vehicle. The LED headlamp comprises a base and a halogen bulb. A spherical lampshade is arranged outside the halogen bulb, one end of the halogen bulb is connected with a far and near light lamp converter, the spherical lampshade is connected with a PCB, the PCB is arranged on a fixing board, a through hole is formed in the fixing board, an antireflection film is arranged on the inner side of the spherical lampshade, the thickness of the antireflection film is gradually reduced from the edge to the center, radiating holes and the PCB are arranged on the base, the base is hollow, motors are fixedly arranged on the two sides of the base, the motors are connected with rotary balls through a rotary shaft, the rotary shaft penetrates through the side walls of the base to be connected with the rotary balls, a radiating device is arranged on the base, and a plurality of containing spaces are formed in the radiating device. According to the LED headlamp for the motor vehicle, the light emitting angle is enlarged and the illuminating effect is improved on the premise that radiating efficiency is not reduced.
Description
Technical field
The present invention relates to a kind of illuminating product, especially a kind of automotive headlight of LED type.
Background technology
The light source of car headlamp uses halogen bulb more at present, as H4 bulb.The luminous volume of halogen bulb is large, and the life-span is short, and the efficiency of light energy utilization is low.Light emitting diode (Light-Emitting Diode, LED), as new type light source, has luminous efficiency high, long service life, and reliability high, has been widely used in various illuminating products at present.Along with the continuous maturation of LED technology and the reduction of cost, become possibility as car headlamp with LED, therefore LED be also referred to as the 4th generation vehicle lamp light source.Adopt the car headlamp of conventional light source, because the cause of conventional light source causes the efficiency of light energy utilization generally on the low side, wanting increases the efficiency of light energy utilization by reflector, but reflector bore is larger, and Hyundai Motor front portion is lower and adopt airflow design, thereby it is less to leave the bore of car headlamp for.Therefore, how exigence at car headlamp bore hour, obtains the maximum efficiency of light energy utilization.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of automotive headlight of LED type, can solve the deficiencies in the prior art, is not reducing under the prerequisite of its radiating efficiency, improves its lighting angle, improves illuminating effect.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows.
A kind of automotive headlight of LED type, comprise base and halogen bulb, described halogen bulb arranged outside has globe holder, described halogen bulb one end is connected with long-and-short distant light converter, described globe holder is connected with PCB circuit board, described PCB circuit board is on fixed head, described fixed head is provided with through hole, described globe holder inner side is provided with anti-reflection film, the thickness of described anti-reflection film is attenuation gradually from edge to center, described base be provided with louvre, PCB circuit board, described base is hollow body, described base both sides are fixed with motor, described motor is connected with and is turned ball by rotating shaft, described rotating shaft through the sidewall of base with turn ball and be connected, on described base, be provided with heat abstractor, in described heat abstractor, be provided with some accommodation spaces, described accommodation space is accommodating for cooling fluid, described accommodation space space is connected with the pump housing, heat abstractor top is provided with fan.
As preferably, the arranged outside of described globe holder has scattering film.
As preferably, the position of described louvre and through hole is crisscross arranged.
As preferably, described motor is connected with controller by wire.
The present invention arranges anti-reflection film in the inner side of globe holder, can improve light penetration, improves brightness of illumination.Anti-reflection film is designed to thickness attenuation gradually from edge to center, can produce the effect of concavees lens, makes light produce scattering, increases lighting angle, can make lighting angle be greater than 270 °.The scattering film of the arranged outside of globe holder can weaken the direction uniformity of LED lamp luminescence, improves illumination uniformity.Under the drive of fan, air-flow enters from louvre, by through hole and base, blows out from fan, has formed a gas channel, has improved radiating effect.The position of louvre and through hole is crisscross arranged, can improve the flow range of air-flow in globe holder, it is large that the fin width be arrangeding in parallel becomes from down to up gradually, can improve the contact area of air-flow and fin, improve radiating effect, the life-span of LED fluorescent tube is brought up to more than 25000 hours.
