Embodiment 1

[0026] A LED car headlight light source, cross-sectional view, perspective view and side view respectively refer to figure 1 , figure 2 and image 3 , including a metal shell 10, the metal shell 10 includes an opening 101, an inner side 102, an outer side 103, an inner bottom 104, and an outer bottom 105 opposite to the inner bottom 104, the opening 101, the inner side 102 1. The inner lower surface forms a cavity, the inner surface 102 is an ellipsoid, a base plate 11 is arranged near the focus of the inner surface 102, an LED chip array 12 is arranged on the base plate 11, and an LED chip array 12 is arranged at the opening. A transparent baffle 14, the cavity is filled with a transparent liquid 13.

[0027] In this embodiment, the LED chip array 12 is formed by arranging two or more of red, green, blue, and yellow LED chips according to a predetermined number and a predetermined pitch. For example, the LED chip array can consist of 8 Red chips, 16 green chips, and 8 blu...

Embodiment 2

[0043] A method for manufacturing an LED automobile headlight source, comprising the following steps:

[0044] A base plate is provided, and the LED chip array is fixed on the base plate;

[0045] A metal shell is provided, and the metal shell includes an opening, an inner surface, an outer surface, an inner bottom surface, and an outer bottom surface opposite to the inner bottom surface, and the opening, the inner surface, and the inner bottom surface form a cavity.

[0046] The inner surface is made as an ellipsoid, the bottom plate is arranged near the focal point of the inner surface, and a transparent baffle is arranged at the opening.

Abstract

The invention discloses a manufacturing method of an LED automobile headlamp light source. The invention further provides the LED automobile headlamp light source manufactured on the basis of the manufacturing method. The LED automobile headlamp light source provided by the invention provides double heat-radiating channels to an LED chip, and can effectively solve heat-radiating problem of an LED automobile headlamp. Simultaneously, the LED automobile headlamp light source provided by the invention realizes the automobile headlamp light source with excellent light distribution by combining an ellipsoid reflecting surface with an LED area light source.

Description

technical field [0001] The invention relates to the field of automobile lighting, in particular to an LED automobile headlight light source and a manufacturing method of the LED automobile headlight light source. technical background [0002] As a lighting source, high-power LEDs have the advantages of small size, low power consumption, low heat generation, fast response, low safety voltage, good weather resistance, and good directionality. Therefore, high-power LEDs have become ideal light sources in the field of automotive lighting. [0003] At present, LEDs have been widely used as auxiliary lamps for automobiles. LEDs have replaced other forms of light sources in many places such as indicator lights, turn signals, brake lights, fog lights, and tail lights. Due to the heat dissipation bottleneck of high-brightness and high-power LEDs, it is still immature to use LEDs as headlights on the front of the car. If this bottleneck can be broken through, the future automotive l...
