Problems solved by technology

[0004] The light guide efficiency of the existing knob light guide structure is not high, and the light guide is uneven. It is necessary to use 2, 3 or even 4 vertical LED light sources to be evenly distributed to ensure that the knob obtains sufficient light transmission brightness and uniformity
Low utilization rate of light sources, high cost, high requirements for structural location and space, often cannot be manufactured due to structural limitations

Abstract

The invention provides a knob light guide structure comprising a PCB, at least one LED light source, an encoder with a shaft handle and a shaft sleeve, a first light guide ring and a second light guide ring. The encoder and the LED light source are arranged on the PCB; the first light guide ring sleeves the shaft sleeve of the encoder; the light guide ring comprises an oval light guide arm and a light guide inner ring with a chamber; the edge of the light guide arm is provided with U-type, V-type and other grooves which are arranged on one side of the LED light source and which are used for receiving the light emitted by the LED light source; the light guide inner ring with the chamber is used for reducing LED light transmission loss during transmission; the second light guide ring is arranged above the first light guide ring and is used for performing the secondary light guidance of the LED light. One single LED light source can be adopted, the light source utilizing efficiency is high, and the light is transmitted evenly.

Description

technical field [0001] The invention relates to the field of vehicle technology, in particular to a knob light guiding structure. Background technique [0002] The development of automotive interiors is changing with each passing day to meet people's higher pursuit of automotive interiors. The exterior design of the car audio must match the interior requirements of the vehicle, and the colorful lighting and interior matching is a very important part of it. Lighting interiors require not only brightness requirements, but also uniformity, aesthetics and matching requirements in a limited design space. [0003] Knobs are important parts on the control panels of various equipment, and people control the normal operation of machinery and equipment by manipulating the knobs. The knob is equipped with a knob backlight and a knob light guide structure, which allows the knob to emit light under night vision or low light conditions, so that people can still see the knob clearly and ...
