目前高校教室照明普遍采用日光灯,其用电量占整个学校电量的40%,但灯光控制不能随进入教室的人数和学生座位的变化灵活调整,造成电能的极大浪费。本设计主要为了节约教室的照明能耗,采用LED作为教室新的光源,综合利用物联网技术选择性区域性开灯、运用PWM脉宽调光技术,灵活调节教室照度。 At present, college classroom lighting commonly used fluorescent lamps, the electricity consumption of 40% of the school electricity, but lighting control can not be flexible with the number of students entering the classroom and seat changes, resulting in a great waste of electricity. The design is mainly to save classroom lighting energy consumption, the use of LED as a classroom new light source, the comprehensive utilization of IOT technology selectively regional lights, the use of PWM pulse width modulation technology, flexible regulation of classroom illumination.
