Description

Technical Field

[0001] This utility model relates to the field of street lights, and in particular to a power line carrier communication dual-lamp controller. Background Technology

[0002] Streetlights are lamps installed along roads to provide illumination at night or when there is insufficient light.

[0003] Current urban street lighting typically uses power switches for manual operation or timed control. Manual control can lead to situations where streetlights cannot be turned on or off promptly during extreme weather. Timed control suffers from mismatches between seasonal changes and ambient brightness.

[0004] In timed control mode, the on and off times of the lights cannot be correlated with the weather that day;

[0005] It can only control the on / off state, and cannot achieve the purpose of changing the brightness of the lights according to changes in ambient brightness. It is not energy-saving, and it cannot know the working status of each street light.

[0006] Traditional street light wiring either involves one switch controlling one street, which poses risks such as a large starting circuit and easy damage to switch contacts due to current surges.

[0007] The wireless solution for the lighting controller, which uses a separate controller, has the risk that the antenna leads need to be led out through a hole in the metal rod, are not waterproof, and are easily perceived as damaged;
