Problems solved by technology

In order to meet the above requirements, the existing LED optical system requires a large number of LEDs and a large depth space
However, the large depth of headlights conflicts with the current popular streamlined body design, and the parts of the headlights near the corners of the body often have less space, which is not conducive to the overall vehicle design

Embodiment 1

[0022] A low-depth reflective LED optical system, the main body is a strip light arranged on the edge of the car light and curved with the outline of the car light, including:

[0023] An LED substrate arranged on the edge of the car light cavity, bent with the shape of the car light, and bonded to the top wall, bottom wall, and side wall of the car light cavity;

[0024] An LED light source arranged on the LED substrate and arranged along the shape curve of the vehicle light;

[0025] A discrete photodistribution mirror arranged on one side of the LED light source as a light-transmitting part on the surface of the car lamp. The centers of the LED light sources are arranged to form a curved surface, and the side of the curved surface close to the surface of the lamp is a curved surface for scattering side, and the other side is the reflection side of the modeling surface;

[0026] One end is set on the free-form reflective surface on the LED substrate located on the reflectiv...

Abstract

Disclosed is a low-depth uniform glowing LED optical system. The body is a strip lamp which is arranged at the edge of a car lamp and curved along with the car lamp contour. The optical system is characterized in that an LED substrate is attached to the top wall, the bottom wall and the side wall of a car lamp cavity. The optical system further comprises a free curved face reflection face with one end arranged on the LED substrate on a shaping curved face reflection side and a side wall which is arranged at the other end of the free curved face reflection face, faces the LED substrate and is in smooth connection with the free curved face reflection face. The free curved face reflection face is a free curved face which is formed through fit fairing connection with LED light source centers serving as focuses, through light axes of the LED light sources and with parabolas arranged in a plane vertical to the shaping curved face. According to the system, limitations of lamp space by car body metal plates are broken through, the usage of LED light sources is greatly reduced, and uniform and soft glowing effects can be provided.

Description

technical field [0001] The invention relates to the lighting field, especially the automotive lighting field, and more specifically relates to a low-depth uniform light-emitting LED optical system. Background technique [0002] As a light source, LEDs have been widely used in the design of lamps and lanterns. Automakers have also put forward various requirements for the luminous effect of LEDs, requiring more uniform and soft light emission. In order to meet the above requirements, the existing LED optical system requires a large number of LEDs and a large depth space. However, the large depth of the headlights conflicts with the current popular streamlined body design, and the parts of the headlights near the corners of the body often have less space, which is not conducive to the overall vehicle design. Reducing the depth space is an urgent problem to be solved for LED lights. Contents of the invention [0003] In order to solve the above technical problems, the purpos...
