Problems solved by technology

At present, there are two installation methods for the light guide structure commonly used in LED car lights: one is to install the light guide structure on the lamp housing due to the need to increase the heat sink when the LED light source power used is relatively large. The disadvantage of this installation method is that The gap between the transition plate and the lens will be larger, which limits the shape requirements; the other is to install the light guide structure directly on the lens when the power of the LED light source used is low and does not require a heat sink. The disadvantage of this installation method is that it limits the usable power of the LED light source
To sum up, there are contradictions between high-power light source, shape design and installation in existing LED lights

Embodiment Construction

[0020] 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.

[0021] At present, the matching installation method and principle of automobile LED lights are as follows: Figure 8-9 As shown, in order to achieve a stable and reliable connection and fixation between the overall appearance that meets the styling requirements, the lamp housing and the light guide, there will be multiple fully constrained parts. First of all, both ends of the light guide are in a fully constrained state (that is, the light guide as a whole is in an over-constrained state). Through dimensional chain analysis, the dimensional chain of this installation structure is a fully closed loop, which will make the installation process difficult or even impossible. Because if the installation of the light guide is completed first, and then it is inst...

Abstract

The invention provides a flexible light guide installing structure of a novel LED car light. A flexible part is introduced to connect a light guide in an appearance installing part and a light guide in a light source installing part, and on the premise that light transmission meets the optical performance requirement, it is not necessary to consider the matched size in the installing process; therequirement for varied car light shapes can be met better, LED light sources of large and small power can be adopted, and installing is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of automobile lamps, in particular to a light guide flexible installation structure of LED lamps. Background technique [0002] Due to the many advantages of high brightness, rich colors, low power consumption, and long life, LED lights are used in more and more cars. A light guide is a structural component that guides the light emitted by the LED from the PCB to the front panel or the light-emitting position. It is generally made of PC material or PMMA material and has good light guiding performance. At present, there are two installation methods for the light guide structure commonly used in LED car lights: one is to install the light guide structure on the lamp housing due to the need to increase the heat sink when the LED light source power used is relatively large. The disadvantage of this installation method is that The gap between the transition plate and the lens will be larger, which limits the sha...
