Lighting system and lighting method

Abstract

The invention provides a lighting system and a lighting method, the lighting system includes a light emitting module, an illuminance sensor and a controller. The light emitting module includes a light emitting unit, and the light emitting module can adjust the output power of the light emitting unit according to the control signal. The illuminance sensor can obtain the illuminance value. The controller is coupled to the light-emitting module and the illuminance sensor, and is adapted to generate a control signal for adjusting the light-emitting unit according to the value difference between the illuminance threshold and the obtained illuminance value, wherein the illuminance threshold is related to the difference between the light-emitting unit and the illuminance sensor Geometry sets the relationship. Accordingly, it is possible to save power and meet usage requirements.

Description

technical field [0001] The present invention relates to an illumination system and an illumination method, in particular to an illumination system and an illumination method that can adjust the brightness according to the environment. Background technique [0002] In the existing electronic devices for lighting, the user must manually control the switch or adjust the brightness according to his needs. [0003] Taking street lights as an example, the current common practice is to set the time points of turning on and off, so that the street lights can function at least after nightfall. However, the time of sunrise and sunset is not the same in different seasons, so the current practice may turn on the street lights when the sky is still bright and cause a waste of electricity, or turn on the street lights when the sky is already dark and cause road damage. poor vision. In addition, weather factors such as cloud thickness, rain, and smog will also affect visibility, which wi...

AI Technical Summary

Problems solved by technology

However, when the light source is far away from the illuminated surface (such as a street lamp), the illuminance sensor cannot accurately measure the reflected light reflected by the illuminated surface (such as a road surface)

Especially in the case of interference objects (such as pedestrians, vehicles, etc.), the signal received by the illuminance sensor will be seriously interfered
