LED optical structure for car lamps

Abstract

The invention discloses an LED optical structure for car lamps. The LED optical structure comprises a pattern structural face which is arranged on the front face of an LED lamp body and used for diffusing light types and an LED light source which is arranged behind the LED lamp pattern structural face. The LED optical structure is characterized in that a light guide inner lens is arranged right behind the LED lamp pattern structural face; the LED light source is arranged on one side of the light guide inner lens, namely, the LED light source is arranged on the rear side of the LED lamp pattern structural face; and a reflecting surface with a free curved surface is formed in the side, corresponding to the LED light source, of the light guide inner lens to ensure that the light from the LED light source reaches the LED lamp pattern structural face of the light guide inner lens after being totally reflected on the reflecting surface with the free curved surface. According to the LED optical structure for car lamps, the composite lighting effects of light sources with different colors are continuous and uniform so as to form continuous and uniform light emitting light bands.

Description

Technical field: [0001] The invention relates to the field of car lamp manufacturing, in particular, the invention relates to an LED optical structure for a car lamp, and the LED optical structure for a car lamp is provided with a thick-walled inner light distribution mirror. Background technique [0002] Currently, LED lights are widely used in car lights. LED car lights can be divided into two categories: signal lights and lighting lights. Signal lights generally include turn signals, brake lights, overtaking lights, and emergency lights, etc., and their function is to provide signals to the outside world. Lighting lights mainly include headlights, fog lights, tail lights, license plate lights, and indoor reading lights. use. [0003] In the past, LED automotive lights used such a thick-walled internal optical structure, and the front irradiation surface of the thick-walled internal optical structure was formed in the form of a pattern (fisheye, columnar, rhombus, hexago...

AI Technical Summary

Problems solved by technology

[0007] However, in the past, since the front of the LED lamp body was provided with a light-diffusing pattern, the back of the LED lamp body needed to be provided with a light source incident surface directly incident on the front of the LED lamp body. The shape has space requirements for the incident surface of the light source set behind the LED lamp body

In addition, since the installation of each LED light source requires a certain heat dissipation area, it also requires a large space requirement. As a result, the installation gap between every two LEDs is greatly restricted, and the gap between every two LEDs is generally not large. Less than 16mm, it is difficult to achieve the effect of completely continuous light
