Embodiment Construction

[0006] As shown in the attached figure, IC1 is a constant current driver for LED bulb lamps sold on the market. The power is determined by the wattage of the bulb lamp. The lamps of the lamps have E27 or B22 lamp holders connected to 220V AC power supply and output DC power. Supply light control circuit and light emitting board.

[0007] As shown in the attached figure, IC2 and peripheral circuits form a light control circuit. The type of IC2 is an integrated chip of 555, and R1 is a photoresistor. During the day, when light irradiates R1, the resistance of R1 shows a low resistance, which causes the potential of R2 to rise. When the raised potential is greater than 2 / 3U CC At night, the pin 3 of IC2 outputs a low level, and the LED of the luminescent board goes out; at night, when night falls, the resistance value of R1 increases, causing the potential of R2 to decrease. When the reduced potential is lower than 1 / 3U CC At this time, pin 3 of 1C2 outputs a high level to drive...

Abstract

The invention provides a light control LED street lamp for institution and school office buildings. A bulb lamp with the light control function is adopted, the lamp can be automatically turned off during daytime and can be automatically turned on at night, the labor intensity of workers is relieved, and the social images of an institution and a school can be improved.

Description

technical field [0001] The invention relates to a light-controlled LED street lamp of an office building of a school. Background technique [0002] At present, there are many kinds of LED energy-saving lamps, such as LED energy-saving lamps with sound and light control, and LED energy-saving lamps with induction. It's just that if these lamps are used as street lights in the office buildings of government agencies and schools, when no one walks around at night, the whole building will appear dark, which will damage the image of the unit. If ordinary LED energy-saving lamps are used, turning on the lights at night and turning off the lights in the morning increases the labor intensity of the staff. Contents of the invention [0003] The present invention is a kind of light control LED street light for office buildings of institutions and schools. The LED bulb type is selected. This light has a light control function, and the light can automatically turn off the light in th...
