Abstract

The invention discloses a single-lamp voltage compensation device of a high-intensity discharge lamp. The device is composed of a power conversion circuit, a reference voltage circuit, a voltage sampling circuit, an AC-DC conversion circuit, a comparison output circuit, a timing sequence output circuit, a drive circuit, a switching circuit, and an output conversion circuit. With the device, the influence on the high-intensity discharge lamp by voltage fluctuation of the power grid can be reduced; and thus a potential safety hazard of the road traffic due to the streetlight illumination change can be eliminated. Meanwhile, the voltage of the high-intensity discharge lamp can be reduced automatically at night and the electric energy wasting and light pollution can be reduced.

Description

technical field [0001] The invention relates to the technical field of voltage compensation circuits, in particular to a voltage compensation device for a single lamp of a high-pressure gas discharge lamp. Background technique [0002] At present, roads are mostly illuminated by high-pressure gas discharge lamps, such as high-pressure sodium lamps and high-pressure mercury lamps. The illuminance is affected by the terminal voltage of the lamp. The illuminance increases and decreases with the increase of the terminal voltage. However, the environment of my country's power grid is complex. Although the street lamp lines use dedicated lines, the voltage of the grid will still fluctuate, which will cause changes in the illumination of street lamps and affect road traffic safety. Especially at night, with the change of line load, the voltage of the power grid shows a change of first decreasing and then increasing, which leads to insufficient illumination of street lamps during tr...
