节能型智能公共设施照明系统设计

A Design of Energy-Saving Intelligent Lighting System Used for Public Facilities

利用人体红外热释电传感器和光照度传感器产生信号,通过单片机处理,以PWM方式对LED灯进行调光,提出了一套用于公共设施节能智能照明系统设计方案.经测试,该控制系统功耗低、结构简单、可靠性稳定性高,可广泛用于教室、办公场所等公共设施的室内外照明.

The paper put forward a set of design used for public facilities and energy saving of intelligent lighting system to dim light leds in PWM way using the human body infrared pyroelectric sensor and light sensor signal through the MCU processing. After the test, the control system is of low power consumption, simple structure, reliability, high stability; therefore, it can be widely used in classrooms, offices and other public facilities, indoor and outdoor lighting.
