Abstract

The invention discloses a street-lamp energy saving device, and the device comprises signal receiving circuits disposed on street lamps; and an LED brightness adjustment apparatus which is connected with the signal receiving circuits. The adjacent street lamps are provided with detection apparatuses, and the detection apparatuses detect whether there are pedestrians and moving objects passing by afront road segment and a rear road segment through pyroelectric infrared sensors, and transmit the information of adjusting the brightness of the street lamps in advance. A pyroelectric detection circuit also can inhibit the signal output, saves the energy. Because the detection apparatuses and the LED brightness adjustment apparatus are set in a separated manner, the device can guarantee that there is enough time for adjusting the brightness of the street lamps in advance when a pedestrian or a vehicle quickly passes through a road.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an energy-saving device for street lamps. Background technique [0002] Nowadays, there are still many wastes of electricity in the use of street lamps in various places. For example, many current street lamps not only have high wattage, but also have a long turn-on time, and some street lamps located in remote roads with few people or in the middle of the night will stay on all night. High-brightness lighting causes energy waste and increases the pressure on power supply tension. Although the relevant departments have also issued relevant policies to reduce the occurrence of various wastes in street lamp electricity consumption, there is still an urgent need for an intelligent device to adjust the actual brightness of street lamps according to actual conditions. In the prior art, although the brightness of the LED lights is adjusted according to the duty cycle, the brightne...
