Example Embodiment

[0022] Example 1:

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

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

Example Embodiment

[0025] Example 2:

[0026] An optical method for LED automobile high beam combination lamps. The white LED light source group and the infrared LED light source group are arranged on a square lattice 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 produces a collimated beam through the corresponding Fresnel lens array in front of it to form a car high beam light distribution. The surrounding white LED light source group and infrared LED light source group are arranged in a staggered manner and pass through Fresnel. The lens group forms a collimated light beam, and then forms the car daytime running light distribution and infrared night vision auxiliary light distribution through the fly-eye lens group.

Example Embodiment

[0027] Example 3:

[0028] A manufacturing method of LED automobile high beam combination lamp, welding or bonding the white light LED light source group and the infrared LED light source group on the aluminum-based PCB board to form a light source lattice, and the Fresnel lens group is clamped to the light source as the focus Install the fly-eye lens group at the position where daytime running lights and night vision auxiliary light distribution are needed.

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 ...
