Description

Intelligent energy-saving lighting system

technical field

The utility model relates to a lighting system, in particular to an intelligent energy-saving lighting system.

Background technique

As the earth's resources are decreasing day by day, people pay more and more attention to energy conservation and emission reduction. Energy conservation and emission reduction have penetrated into almost every field of people's life. As a field with relatively large energy consumption, the lighting field is imperative to achieve energy saving and emission reduction. the

At present, the lighting system in many occasions only has a simple switch, which is to turn off during the day and turn on after the evening. Such a system has a simple structure, but there are still many inconveniences in the actual application process. Due to seasonal changes and climate effects, the length of each day and night is different. In summer, when the light is still sufficient, the lighting system has been turned on, resulting in energy waste; and in winter, the lighting system cannot work when the sky is dark. In response, some technicians have designed voice-activated lighting systems that only work when someone passes by. But these systems still have shortcomings. For example, the photosensitive lighting system, in the dark, is still on even if no one passes by, which naturally causes energy waste. And the sound control system can't play the effect of prompting when people are in the distance, and because the outside has very big noise, can all light up when the car alarm sounds, causes waste. And once the voice control system breaks down, it is difficult to find out, which makes life more inconvenient.
