Intelligent light-emitting diode (LED) lamp driving system

Abstract

The invention provides an intelligent light-emitting diode (LED) lamp driving system which comprises a controller module, a constant current driving module and a delay module, wherein the constant current driving module is connected with a pulse-width modulation (PWM) dimming module. A controller comprises a voice-operated module and a light-operated module, judges the environmental people flow condition and the environmental light and feeds the result to the PWM dimming module. The PWM dimming module adjusts the brightness of an LED lamp according to the output current of the constant current driving module. The delay module controls the lightening time of the LED lamp. The intelligent LED lamp driving system can effectively monitor and detect the people flow and light changes in the surrounding environment and timely turn on and turn off a lamp source and adjust the light, can save a large amount of electricity, and greatly improves the electricity utilization efficiency of the LED lamp through the special dimming module.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to an intelligent driving system for LED lamps applied in public places. Background technique [0002] Due to the deterioration of the global environment, people pay more attention to environmental protection and energy saving and emission reduction. As a green lighting product with low energy consumption and long life, LED lighting products have become the mainstream of energy-saving products in the global lighting field, and high-power bright LED lighting It is also the mainstream trend of lighting and lighting systems in the world in the future. High-power LED has the characteristics of high brightness, energy saving and environmental protection, high safety and stability, and saves 60%-70% of electricity compared with traditional light sources, so it is also widely used in various public fields. Traditional lighting fixtures in public areas are generally realized by sound ...

AI Technical Summary

Problems solved by technology

Traditional lighting fixtures in public areas are generally realized by sound and light control delay controllers. When the light is dark or at night, it can effectively realize "the lights are on when people come, and the lights are off when people go away". However, due to the switch it uses It is a mechanical controller such as a relay, so it will be easily damaged due to frequent switching and cause inconvenience in places with a lot of traffic; in addition, it cannot sense ambient light, even in the case of no lighting during the day, it will Provide lighting according to the established trigger conditions, which will also cause waste of energy
