Problems solved by technology

[0006] The LED daytime running lights and night vision system of the headlight combination are designed in the vicinity of the low beam and high beam. Due to the complex structure, in order to increase its shock resistance, it must be designed as an integrated structure. Once a light source is damaged, it must be replaced. The entire car light assembly will cause the car owner to spend a lot of money on replacing the car lights in the future.

Embodiment 1

[0023] An LED car high beam combination lamp, which comprises: a high beam combination lamp housing 1, an aluminum-based PCB board 2 is housed in the high-beam combination lamp housing, and the aluminum-based PCB board is connected to a white LED light source group 3. The white LED light source group is connected to the infrared LED light source group 4, a Fresnel lens group 5 is installed in front of the infrared LED light source group, and a fly-eye lens group 6 is installed in front of the Fresnel lens group.

[0024] In the LED car high beam combination lamp, the white LED light source in the white LED light source group has a light emitting angle of 30-80 degrees, and the infrared LED light source in the infrared LED light source group has a light emission angle of 30-80 degrees Angle, the diffusion angle of the fly-eye lens in the fly-eye lens group is ±45 degrees.

Embodiment 2

[0026] An optical method for an LED car high beam combination lamp, the white LED light source group and the infrared LED light source group are arranged on a square dot matrix aluminum-based PCB board, and the aluminum-based PCB board is placed at the focal position of the Fresnel lens group, The light emitted by the LED in the middle position passes through the corresponding Fresnel lens array in front of it to generate a collimated beam to form the light distribution of the high beam of the car. The surrounding white LED light source groups and infrared LED light source groups are arranged alternately. The lens group forms a collimated light beam, and then forms the light distribution of the car daytime running lights and the auxiliary light distribution of infrared night vision through the fly eye lens group.

Embodiment 3

[0028] A manufacturing method of LED automobile high-beam combination lights, welding or bonding white LED light source groups and infrared LED light source groups on an aluminum-based PCB to form a light source lattice, and clamping a Fresnel lens group on the light source as the focal point Install the fly-eye lens group in the coaxial position where daytime running lights and night vision auxiliary light distribution are required.

Abstract

Disclosed are optics and a production method for a light emitting diode (LED) automobile high beam combination lamp. In existing automobile high beams, generally, a tungsten halide lamp serves as a light source, and the light source is high in working temperature, short in service life and poor in light efficiency. The LED automobile high beam comprises a high beam combination casing (1), wherein an aluminum-based printed circuit board (PCB) (2) is installed inside the high beam combination casing, the aluminum-based PCB is connected with a white light LED light source group (3), the white light LED light source group (3) is connected with an infrared LED light source group (4), a Fresnel lens group (5) is installed on the front portion of the infrared LED light source group, and a fly-eye lens group (6) is installed on the front portion of the Fresnel lens group. The optics and the production method are used in the automobile high beam combination lamp.

Description

[0001] Technical field: [0002] The invention relates to optics and a manufacturing method of an LED automobile high beam combination lamp. [0003] Background technique: [0004] Tungsten halogen lamps are generally used as the light source in the existing high beam lights of automobiles, which have high working temperature, low service life and poor luminous efficiency. In addition, higher-end models are equipped with LED daytime running lights and infrared night vision systems. These lamps are distributed in the shape of the headlights, making the shape more complicated. Due to the scattered distribution of the light source, in order to improve the mechanical strength and increase the shock resistance, it can only be designed as an integrated structure. Once a lamp is damaged, only the car light assembly can be replaced, which cannot be achieved by replacing the light source, causing a cost to the car owner. Big waste. [0005] Although the cost of using tungsten-halogen ...
