Energy-saving and environmentally-protecting lighting device

Abstract

The invention discloses an energy-saving and environmentally-protecting lighting device. The lighting device comprises a power supply, a load, a switch, a rectifier bridge, a timer, a thyristor, an inductor, a first resistor, a second resistor, a third resistor, a fourth resistor, a fifth resistor, a first capacitor, a second capacitor and a third capacitor. A b point of the rectifier bridge serves as the output end of the rectifier bridge and is connected with one end of the inductor; one end of the load is connected with the anode of the thyristor; the cathode of the thyristor is grounded; the control electrode of the thyristor is connected with one end of the second resistor; the other end of the second resistor is connected with the pin 3 of the timer; the pin 2 of the timer is connected with one end of the switch; one end of the fourth resistor is connected with the pin 6 and pin 7 of the timer; the other end of the four resistor is connected with one end of the second capacitor; and the other end of the second capacitor is grounded. The lighting device, with switch control and intelligent control being combined effectively, is simple in structure and convenient to operate, can save electric energy effectively, and is low in cost.

Description

technical field [0001] The invention relates to a lighting system, in particular to an energy-saving and environment-friendly lighting device. Background technique [0002] With the rapid development of the national economy and social progress, education has been paid attention to and valued by the whole society. The scale of the campus has also continued to expand with the increase in the number of educated people, and the number of classrooms has also increased significantly. In order to make teachers and students feel comfortable The teaching and learning environment, whether it is the classroom area, facilities and illumination, the school has made great efforts within its capabilities. [0003] However, due to the school's open management model and the lack of awareness of energy conservation among all employees, it is still common to turn on the lights in the classrooms of the school when the indoor illumination is high during the day. Energy shortage is a new issue f...

Problems solved by technology

[0004] However, the overall level of lighting intelligence in my country is still relatively low, and it is unacceptable to apply the dimming control method to ordinary classrooms and lecture halls because of the high cost. So far, fluorescent lamps are mostly used in school teaching buildings, and dimming control requires special Dimming ballasts are relatively cumbersome, so switch control is the main control method for school classroom lighting

[0005] In the prior art, there is no lighting system that can effectively combine switch control and intelligent control with low cost
