Automotive interior lights based on capacitive touch switches

Abstract

The invention relates to an automobile interior lamp based on a capacitive touch switch. A shell is detachably installed on a lampshade. A reflecting mirror arranged between the lampshade and the shell is divided into two reading lamp reflecting areas and two backlight reflecting areas along the center line in the length direction, a circuit board with reading LEDs and backlight LEDs is vertically installed on the back of the reflecting mirror, switch panels with markers are installed in backlight lampshades on the two sides of the lampshade, light guide plates with the capacitive sensors on the upper portions are installed on the upper portions of the switch panels, the light emitting faces of the backlight LEDs are opposite to light guide posts vertically arranged on the light guide plates, the capacitive sensors are connected with the circuit board through flexible flat cables, and the backlight lampshades are touched to control the corresponding reading LEDs to be turned on and off. According to the automobile interior lamp, the structure is reasonable, the switch service life can be prolonged by arranging the capacitive sensors in the lampshades, the markers on the switch panels can be displayed through backlight sources, operation is convenient and accurate, reading LEDs are controlled to be turned on and off, and installation and maintenance are convenient.

Description

technical field

[0001] The invention relates to an automotive interior lamp based on a capacitive touch switch, which is used in the technical field of automotive interior lamps. Background technique

[0002] With the rapid development of automotive electronics, a large number of electronic devices have been applied to the entire vehicle, among which there are not only a large number of switches and buttons, but also as customers have higher and higher requirements for installation and control, traditional switches And buttons are faced with various constraints such as temperature, humidity, pollution, and cost. However, the existing interior lights of automobiles are operated by mechanical switch buttons, which will generate certain noises, occupy a small area, and cannot be miniaturized. At the same time, there are also problems of inconvenient loading and unloading and maintenance. Contents of the invention
