Embodiment Construction

[0013] In order to enable those skilled in the art to fully understand the technical solutions and beneficial effects of the present invention, further description will be given below in conjunction with specific examples.

[0014] Such as Figure 1-2 The PCBA of a double-sided LED shown in the figure is combined with the reflective bowl to realize the function structure of the steering and brake lights of the taillight, including a chrome-plated strip 1, an outer lens 2, a reflective bowl 3, a PCBA4 of the double-sided LED, and a housing 5. Among them, the chrome-plated strip 1 welded on the surface of the outer lens 2 divides the lamp body into two functional areas: the turn signal functional area 6 and the brake light functional area 7. The two functional areas are respectively emitted by the LED light source on the front or back of the same PCB board. After the light is reflected and refracted, they independently realize the steering and braking functions. Further, the PC...

Abstract

The invention discloses a structure combining a PCBA with two-side LEDs with a reflection bowl to achieve a steering function of a tail light and a function of a brake light. According to the structure, a shell body is taken as a main assembly body, one PCB is fixedly located in the middle of the shell body through a clamping groove to form one sub assembly body, the shell body is partitioned intoupper and lower light chambers through a chrome plated strip, LED light sources of the upper and lower sides of the PCBA respectively and vertically give out light up and down, and after reflection of the reflection bowl, the functions of a steering light and the brake light are separately achieved. The structure not only can generate a uniform lighting effect on the premise of meeting the statutory optical requirements, but also can meet the functions in the narrower and narrower space according to the shape trend, the PCBA with the two-side LEDs is used for installment of the PCB in the smallest space, the one PCBA can achieve two optical functions, and through the design, not only is the shell body space saved to meet the requirement for a thin and long shape, but also the reflection mode of the reflection bowl is utilized for making the whole illuminating effect more uniform.

Description

technical field [0001] The invention relates to the technical field of automobile lighting, in particular to a PCBA of double-sided LEDs combined with a reflective bowl to realize the function structure of steering and brake lights of tail lights. Background technique [0002] Currently on the market, the steering and braking functions of automobile taillights are mainly implemented in the following forms: two different light bulbs, two PCBAs with LEDs on one side, plus inner lenses or two reflective bowls, LED plus light bar, etc. to realize steering and braking functions . These implementation forms have disadvantages such as uneven luminescence, being limited by space positions, etc. Therefore, the present invention provides a novel implementation form of steering and braking functions of automobile taillights. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings existing in the prior art, and provide a...
