Embodiment Construction
[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0014] see figure 1 , figure 2 As shown, the present invention includes an ambient illuminance collection part, an A / D conversion part, a central control part and a light emitting element. Wherein, the ambient illuminance collection part is used to collect the intensity parameters of the ambient light and convert them into analog electrical signals, which is mainly composed of a light sensor and a signal amplifier. The light sensor converts the light intensity of the surrounding environment into an electrical signal and outputs it to the signal amplifier, and the signal amplifier amplifies the weak signal from the light sensor for subsequent signal processing. The light sensor can be a photoresistor, a photodiode or a phototransistor.
[0015] The A / D conversion part is used to sample the electrical signal from the ambient light collection part and conver...
