AI Technical Summary

Technical Problem

Existing automotive reading lights using PEDOT or ITO transparent conductive materials suffer from unstable touch sensitivity, poor aesthetics, and insufficient durability. In particular, they are prone to poor contact or loose connections under temperature changes.

Method used

Stainless steel sheet electrodes are used, which are connected to the PCBA board through an elastic connection structure. The lens is made of transparent PC material, and the combination of arc-shaped contact parts and retaining rib structure ensures the stability and aesthetics of the electrical connection.

Benefits of technology

It achieves stable electrical connections under temperature variations, eliminates visible shadows, improves the uniformity of touch sensing and the aesthetics of the product, and extends its service life.

Abstract

The utility model provides a kind of capacitive touch type car reading lamp, including the shell with opening, PCBA board being located in shell, and LED lamp and touch chip being located on PCBA board, opening is equipped with lens, lens has the light-transmitting area of being opposite to the arrangement of LED lamp and the non-light-transmitting area of being around light-transmitting area, the inside of non-light-transmitting area is equipped with metal sheet electrode, this metal sheet electrode is electrically connected with PCBA board by elastic connecting structure.The metal sheet electrode is made of stainless steel material, instead of traditional PEDOT or ITO transparent conductive layer, fundamentally eliminates the visible shadow produced by electrode grid or pattern under backlight, ensures that the light emitting surface is uniform and pure, significantly improves the product's aesthetic and visual level;Elastic connecting structure can always keep contact with touch sensing pad under the action of its own elasticity, realizes stable electrical connection.
