Abstract

The invention discloses an LED lamp based ambient light induction controller which comprises a microcontroller, a voltage stabilizing circuit and an illumination detection circuit. The voltage stabilizing circuit is connected with an LED driving circuit and provides a working voltage for the microcontroller and the illumination detection circuit; the microcontroller is provided with a PWM module, and is connected and drives a lamp control switch via the PWM port, the light control switch is connected with an LED lamp, and the microcontroller controls the PWM output frequency to control the light emitting frequency of the LED lamp; and at the same time, the microcontroller converts an illumination change value detected by the illumination detection circuit into an electric signal, compares the electric signal with a preset voltage value, and controls switching and brightness of the LED via the PWM port according to a comparison result. Thus, the lamp is controlled automatically according to ambient light change, and a lot of labor and energy are saved; and the light induction controller can be installed in any part of the lamp, and the product experience is extremely good.

Description

technical field [0001] The invention relates to the technical field of light control equipment, in particular to an ambient light sensing controller based on LED lights. Background technique [0002] The light sensor controller of the lamp can realize the automatic control that the lamp is not on during the day and automatically turns on when it is dark. It is a very practical and convenient product. However, the traditional light-sensing controller cannot recognize the luminous light of the lamp itself and the visible light of the environment, that is to say, it cannot distinguish whether it is day or night when it is interfered by its own light. The installation of lamps is subject to many restrictions, causing great trouble; and this method cannot achieve accurate constant light lighting, cannot accurately avoid self-light interference, and recognize the intensity of ambient light to make light compensation. [0003] The popularity of LED solid-state lighting provides a ...
