Description

LED street light that automatically senses and adjusts brightness

Technical field

The utility model relates to the field of road illumination, in particular to an LED street lamp which automatically senses and adjusts brightness.

Background technique

Because LEDs are characterized by energy saving, environmental protection, long life and small size, they are often used in street lighting. The traditional street lamps are timed. When the light is strong, turning on the lights wastes a lot of electric energy. When it is raining, the street lights are not turned on and the street lights are not activated. One solution is to set the street light as a photosensitive LED street light. However, when the existing photosensitive LED street light detects that the surrounding brightness is low, the street light switch is directly turned on, and the automatic adjustment cannot be performed. In addition, the light sense measurement is inaccurate. It will also waste the corresponding resources.

The above defects are worth solving.
