Abstract
An electronic lock includes a lock assembly configured to switch between a locking state and an unlocking state, and a control unit electrically connected to the lock assembly. The control unit includes an operation panel configured to receive a user input, a light sensor configured to measure intensity of ambient light and generate a light-sense signal, a proximity sensor configured to generate a wake signal, a backlight module configured to emit light from the operation panel, and a control module electrically connected to the lock assembly, the operation panel, the light sensor, the proximity sensor, and the backlight module. The control module is configured to control operation of the lock assembly based on the user input, activate the light sensor to measure the intensity of the ambient light, activate the backlight module to emit the light, and control the backlight module to adjust brightness of the light emitted thereby.
