Abstract
The invention discloses an LED adaptive dimming classroom lamp and a control method thereof. The invention relates to dimming technologies of an LED classroom lamp, and solves problems that LED lamps in the classroom are constant in light intensity and that the brightness cannot be adjusted intelligently. According to the invention, a light sensation device transmits sensed light sensation signals to an intelligent controller, a wireless terminal transmits a preset light intensity value to the intelligent controller, the intelligent controller compares the light intensity sensed by the light sensation device with the preset light intensity, and the intelligent controller transmits 0-10V pulse width modulation signals to an LED dimming driver according to different comparison results, thereby controlling current outputted by the LED dimming driver for the LED classroom lamp. The LED classroom lamp can carry out intelligent adjustment automatically according to light changes of an external environment so as to maintain a constant illumination value of the actual environment, thereby not only meeting the brightness required by the classroom, but also achieving a purpose of saving energy, and being applicable to lighting of the classroom.
