Embodiment 1

[0014] A high-mounted stop lamp with ultra-uniform display of characters, which comprises: a high-mounted stop lamp housing 1, a PCBA2 and a radiator 4 are respectively installed in the high-mounted stop lamp housing, and the PCBA and the described The radiator 4 is connected, and a group of LED light sources 3 are respectively welded on the PCBA. The housing of the high-position brake light is clamped with the light guide 7. There are triangular or trapezoidal optical teeth on the back of the light guide, and the inner mirror 5 and the mask 6 are connected by clamping or welding. There is no light distribution pattern in the middle of the inner mirror, and there are compound eye patterns facing inward on both sides. The mask is welded and fixed to the high-position brake lamp housing. , the mask is black and red two-color injection molding and there are characters printed in the film inside the mask.

Embodiment 2

[0016] According to the high-mounted stop lamp with super-uniform display of characters described in Embodiment 1, the material of the high-mounted stop lamp housing is a plastic frame structure, which has the positioning points of the PCBA and the radiator inside, The LED light source is red, the angle of the LED light source is 120 degrees, the distance between the LED light source and the end face of the light guide is 0.5mm-3mm, and there is a triangular or trapezoidal optical lens behind the light guide. Teeth, wherein the width of the optical teeth is not greater than 5mm, the height of the teeth is not greater than 2mm, and the dispersion angle of the compound eyes of the internal glasses is less than 25 degrees in both the horizontal and vertical directions.

Embodiment 3

[0018] A method for manufacturing a high-position brake light with super-uniform display of characters, the method includes the following steps: first, hang and paste a red LED light source on a PCBA board, the PCBA board is fixed on a radiator, and the heat dissipation The device is fixed on the brake light housing, the distance between the red LED light source on both sides and the light guide is not more than 3mm and not less than 0.5mm, and the red LED light source directly illuminates the light guide to form a uniform line source of point light source, and the line light source is irradiated inside The prescription light distribution is completed on the glasses, and the in-mold printing characters of the mask are finally displayed. The inside glasses are fixed to the mask by clamping or welding, and finally the mask and the shell are welded.

[0019] The working process of this application is to first convert the LED point light source into a line light source through the ...

Abstract

The invention discloses a high-position brake lamp for super-uniformly displaying characters and a manufacturing method thereof. An existing automobile high-position brake lamp is single in modeling,the display effect is mostly red dots or red square blocks, and the effect of the high-position brake lamp with some display characters is uneven due to the fact that stickers are additionally arranged on a brake lamp mask or a mask with scattering materials is directly irradiated by a light source inside the high-position brake lamp. The high-position brake lamp comprises a high-position brake lamp shell (1), a PCBA2 (2) and a radiator (4) are mounted in the high-position brake lamp shell, the PCBA is connected with the radiator, a set of LED light sources (3) are welded to the PCBA, the high-position brake lamp shell is connected with a light guide (7) in a clamped mode, and triangular or trapezoidal optical teeth are arranged on the back of the light guide, and an inner matching mirror(5) is connected with a mask (6) through clamping or welding. No light distribution pattern exists in the middle of the inner matching mirror, inward compound eye patterns are arranged on the two sides of the inner matching mirror, and the mask and the high-position brake lamp shell are welded and fixed. The high-position brake lamp is used for super-uniformly displaying the characters.

Description

Technical field: [0001] The invention relates to a high-position brake lamp for super-uniformly displaying characters and a manufacturing method thereof. Background technique: [0002] The existing high-mounted brake lights of automobiles have a single shape, and the display effect is mostly red dots or red squares. Some high-mounted brake lights that display characters are equipped with stickers on the brake light mask or directly irradiate the mask with scattering materials with a light source inside. , the effect is uneven. It directly affects the response ability of the driver of the follow-up vehicle, and there is a hidden danger to the driving safety of the follow-up vehicle. Invention content: [0003] The purpose of the present invention is to provide a high-position brake light with super-uniform display of characters and its manufacturing method. This structure first converts the LED point light source into a line light source through the light guide, and then i...
