Abstract

A projection-type automotive headlight includes a lamp housing with a light distribution lens mounted on it. The headlight is characterized by: a convex lens at the front end, a light-shielding plate in the middle, and an LED lamp at the rear end. The LED lamp is positioned above a freeform surface reflector, and an integrated circuit board below the LED lamp is supported by a heat sink. The heat sink is connected to the lamp housing via an adjustment device. This technology fully utilizes the luminous efficiency of the light source, saves energy, extends its service life, and is compact in size. Its internal design provides ample space, facilitating a rational internal layout and aesthetically pleasing and novel design.

Description

Projector car headlights

technical field

The utility model relates to a projection type automobile headlamp, which belongs to the field of automobile lamps.

Background technique

Most of the traditional automobile headlights use incandescent lamps, halogen lamps, gas discharge lamps, etc. as light sources. With projection headlights, a low-beam light group occupies most of the volume of the lamp body, which greatly restricts the overall design of the lamp. After the traditional headlight is turned on, the temperature inside the lamp is high, and water mist is easily generated, which affects the appearance and the life of other parts of the lamp, and the power consumption is also large, which is not conducive to energy saving.

Contents of the invention

The purpose of the utility model is to provide a projection type automobile headlight, which can save energy, prolong the service life, and is small in size, which is beneficial to the rational layout of the lamp, beautiful appearance and novel design.

The technical scheme of the utility model is: a projection type automobile headlamp, which has a lamp housing, and a light distribution mirror is installed on the lamp housing, and is characterized in that: the front end of the lamp housing is equipped with a convex lens, the middle part is equipped with a shading plate, and the rear end is equipped with a There is an LED lamp, the top of the LED lamp is opposite to the free-form surface reflector, the integrated circuit board under the LED lamp is supported by a radiator, and the radiator and the lamp housing are connected through an adjustment device.

With the above-mentioned technical solution, due to the small size of the LED light source, the layout inside the lamp can be made more reasonable; the free-form surface reflector has changed from the original rotating surface to a half-section, which reduces a certain volume and reserves more space for the internal design. The appearance of the whole lamp tends to be more beautiful and novel; the use of LED light source can reduce the temperature inside the lamp to below 60 ℃, greatly reduce the possibility of water mist, and prolong the service life of each part of the lamp; through the half-section The design makes full use of the luminous efficiency of the light source while reducing the volume, without wasting any light, and can save 70% of electricity; the use of free-form surface light distribution makes the light pattern clearer, the light distribution more accurate, the appearance more novel, and can be Meet the requirements of the national standard GB4599.

Description of drawings

Fig. 1 is a structural schematic diagram of the projection type automobile headlight of the present invention.

Fig. 2 is a sectional view along A-A of Fig. 1 .

In the figure, 1 is a free-form surface reflector, 2 is an LED lamp, 3 is a radiator, 4 is a light shield, 5 is a convex lens, 6 is a light distribution mirror, 7 is a lamp housing, and 8 is an adjustment device.

Detailed ways

The light distribution mirror 6 is installed on the lamp housing 7 of the projection type automobile headlight, the front end of the lamp housing 7 is equipped with a convex lens 5, the middle part is equipped with a light shield 4, the rear end is equipped with a free-form reflector 1, and the LED lamp is installed in the lamp housing. 2. The LED lamp is opposite to the free-form surface reflector, the integrated circuit board under the LED lamp is supported by the radiator 3, and the radiator and the lamp housing are fixedly connected by the adjustment device 8. The LED lamp 2 is a high-power white light source, and the radiator is made of aluminum alloy, which is fixed under the integrated circuit board of the light source to dissipate heat, and simultaneously plays a role of supporting the light source. The free-form surface reflector 1 adopts a half-section structure and performs light distribution through the free-form surface design, which can reflect and redistribute the light emitted by the LED lamp. Working principle: After the power is turned on, the light emitted by the LED light is reflected by the free-form surface reflector, and part of the light is blocked by the shading plate, and then passed through the convex lens to form a clear cut-off line of light and dark.

Claims (1)

1. projection car headlamp, has lamp housing, lens is housed on the lamp housing, it is characterized in that: the lamp housing Inner Front End is equipped with convex lens, shadow shield is equipped with at the middle part, and the LED lamp is equipped with in the rear end, and LED lamp top is relative with free-form surface mirror, surface-mounted integrated circuit below the LED lamp is supported by radiator, and radiator is connected by adjusting device with lamp housing.
