Embodiment 1

[0017] A switch panel backlight button that can automatically adjust brightness according to changes in ambient light intensity, such as figure 1 As shown, it includes a touch button 2 arranged on the switch panel 1, and the touch button 2 is provided with a backlight control circuit. Such as image 3 As shown, the backlight control circuit includes a backlight, a triode, a photosensitive sensor and a power supply. The backlight adopts an LED lamp D1, the photosensitive sensor adopts a photoresistor D2, and the power supply is a 3.3V direct current converted from a 220V alternating current through a power conversion module. Power supply (the power conversion process is a prior art, and will not be repeated here). The anode of the LED lamp D1 is connected to the 3.3V DC power supply through the first resistor R3, and its cathode is grounded; at the same time, the anode of the LED lamp D1 is also connected to the collector of the triode Q1 through the current limiting resistor ...

Embodiment 2

[0019] A backlight button on the socket panel that can automatically adjust the brightness according to the change of ambient light intensity, such as figure 2 As shown, it includes a touch button 2 and a socket 4 arranged on the socket panel 3 , and a backlight control circuit is arranged inside the touch button 2 . The specific structure of the backlight control circuit is the same as that in Embodiment 1, and will not be repeated here.

Abstract

The invention relates to the technical field of an intelligent switch / socket panel, especially to a backlight button, capable of automatically adjusting brightness according to ambient light intensity change, of the switch / socket panel. The backlight button comprises a touch button arranged on the switch / socket panel; the touch button is internally provided with a backlight lamp control circuit; and the backlight lamp control circuit comprises a backlight lamp, a triode, a photosensitive sensor and a power supply, wherein one end of the backlight lamp is connected to the power supply via a first resistor, the other end of the back lamp is grounded, the emitter electrode of the triode is connected with the power supply, the collector electrode of the triode is connected between the first resistor and the backlight lamp via a current-limiting resistor, the base electrode of the triode is connected with one end of the photosensitive sensor via a second resistor, the other end of the photosensitive sensor is grounded, and a biasing resistor is connected between the emitter electrode and the base electrode of the triode in parallel. The backlight button can adjust the brightness of the touch button automatically according to ambient light change, so that the switch button can be brightened in daytime to make the button more beautiful, and the switch button is darkened automatically at night when light is dark and does not influence sleeping of users.

Description

technical field [0001] The invention relates to the technical field of intelligent switch / socket panels, in particular to a switch / socket panel backlight button capable of automatically adjusting brightness according to changes in ambient light intensity. Background technique [0002] With the development of science and technology and the improvement of living standards, people have higher and higher requirements for the aesthetics and convenience of home furnishing products, and various household products have emerged as the times require. In order to meet people's requirements for aesthetics, many brands of switch / socket panels are equipped with touch buttons with backlights, which can brighten the panel and make it more beautiful. The brightness of the backlight of the existing switch panel is fixed. In order to reflect the product grade during the day, the backlight is usually adjusted to the brightest. In this case, the brightness of the backlight is too bright at night...
