Embodiment 1

[0065] See Figure 1 to Figure 4 , the automotive lighting device of this embodiment includes a housing 1 , a bezel 2 and an optical system 3 .

[0066] The bezel 2 is mounted inside the casing 1 . The optical system 3 is mounted on the bezel 2 . The optical system 3 includes an optical unit 4 . The optical unit 4 includes at least one light emitting component 5 and a mask 6 covering the outside of the light emitting component 5 .

[0067] The light emitting component 5 includes a carrier 5-1, a reflector 5-2, a light guide 5-3, a homogenizing layer 5-4, a functional layer 5-5 and a light source 5-6. The carrier 5-1, the reflection mirror 5-2, the light guide 5-3, the homogenizing layer 5-4 and the functional layer 5-5 are arranged in sequence from bottom to top. The functional layer 5-5 is provided with at least one layer. The light source 5-6 is arranged at one end of the light guide 5-3, and the light source 5-6 includes a PCB board and at least one LED light-emitting ...

Embodiment 2

[0078] See Figure 11 , this embodiment is basically the same as Embodiment 1, except that the optical system 3 is composed of a plurality of optical units 4, and each optical unit 4 includes a light-emitting component 5, so that at least one or more functional requirements can be achieved .

[0079] Figure 12 and Figure 13 , to achieve the above effect by simultaneously lighting up multiple optical units 4

[0080] From Figure 12 Looking at the lumen intensity distribution diagram above, the light distribution can be divided into several regions by virtual lines. All points on zone a of the brake light achieve the highest lumen distribution, and all point lumen values ​​are in the range of 75%-100% of the maximum lumen value. Similarly, all spot lumens on zone b are between 50% and 75% of maximum lumen. The lumen value of all points in area C is within the range of 25%-50% of the maximum lumen value, and the lumen value of all points in area D is within the range of ...

Embodiment 3

[0088] See Figure 18 , this embodiment is basically the same as Embodiment 2, except that each optical unit 4 is provided with two light-emitting assemblies 5 up and down, and the two light-emitting assemblies 5 emit light of different colors.

Abstract

The invention discloses an automobile lighting device, which comprises an outer shell, a decorative ring and an optical system. The decorative ring is mounted in the outer shell, and the optical system is mounted on the decorative ring and comprises at least one optical unit. Each optical unit comprises at least one light-emitting component and a mask which covers the at least one light-emitting component externally. Each light-emitting component comprises a carrier, a light guide, at least one functional layer and a light source, wherein the carrier, a reflector, the light guide and the at least one functional layer are in sequential arrangement from bottom to top, wherein the light source is arranged at one end of the light guide and comprises a PCB board and at least one LED light-emitting chip packaged on the PCB board. The masks cover surfaces of the functional layers and lateral sides of the carriers, the light guides and the functional layers. By PCB packaging of the micro-sizeLED light-emitting chips, displaying of complex patterns in various colors is realized, and the automobile lighting device is low in power consumption, low in cost, long in service life and quite suitable for being applied to automobile signal lights.

Description

technical field [0001] The invention relates to an automobile lighting device. Background technique [0002] Currently, LEDs are mainly used in car lights as ordinary LEDs and OLEDs. Ordinary LEDs cannot display complex patterns. Although OLEDs can display complex patterns, the cost is too high. Therefore, the applicant aims to design an automotive lighting device that uses ordinary LEDs but can display complex graphics. Contents of the invention [0003] The object of the present invention is to provide an automobile lighting device which adopts ordinary LEDs but can display complex graphics, and reduces the cost of the automobile lamp. [0004] The technical solution for realizing the purpose of the present invention is: an automotive lighting device, including a casing, a decorative ring and an optical system; the decorative ring is installed in the casing; the optical system is installed on the decorative ring; the optical system includes at least one Optical unit; t...
