Signal processing method for light-operated lighting luminaire

Abstract

The invention relates to a signal processing method for a light-operated lighting luminaire. The processing method includes the following steps: reading an ambient brightness voltage value; determining an ambient light brightness threshold value; lightening the light-operated lighting luminaire; re-reading the voltage value; determining a reference voltage value; and judging whether to turn off the luminaire. The signal processing method reads the ambient brightness voltage value by utilizing an AD conversion function of a single-chip computer, thereby being able to accurately control lightening and extinguishment of the luminaire according to natural light intensity of environment; the method senses illumination intensity through a light sensing module and converts the illumination intensity into a voltage signal, the signal processing method for the light-operated lighting luminaire is simple and convenient, when a light change is detected, an illumination module is controlled to perform illumination, and the control method is convenient to operate and high in efficiency; and the method solves the problem that a traditional light-operated lighting luminaire enables a light-sensitive detector of the luminaire to misjudge a day to be daytime due to luminescence of the luminaire itself, thereby avoiding generation of a phenomenon of flashing lights.

Description

technical field [0001] The invention belongs to the technical field of signal processing of light-controlled lighting fixtures, and in particular relates to a signal processing method of light-controlled lighting fixtures. Background technique [0002] In recent years, with the rapid development of electronic technology, people always hope to be able to change the light on and off according to the intensity of external light. For example, street lights in cities or lights in corridors always hope When the light is strong, the lamp is turned off, and at night, the lamp can be turned on. For example, the emergency light after a sudden power failure, it is hoped that the emergency light will be turned on when the lamp suddenly goes out. The existing solution to this problem is to use Manually operate the lamps. When the lamps need to be lit, the lamp switch is manually closed. When the lamps need to be extinguished, the lamp switch is manually disconnected. This manual operatio...
