Smart LED (light-emitting diode) street lamp

Abstract

The invention relates to the technical field of illumination lamp fittings, and particularly relates to a smart LED (light-emitting diode) street lamp. The outer end of an outer shell is provided with heat radiating fins; two sides of the outer shell sag to form an inversed U shape; the saggy parts at the two sides are internally provided with connecting grooves; glass seal plates are embedded in the connecting grooves; the inner end surface of the outer shell is provided with a strip-shaped groove and an aluminum base plate; the surface of the aluminum base plate is provided with an LED lamp bead; a lamp body is internally provided with a smart driving power supply and a smart sensor; the smart driving power supply drives the LED street lamp by utilizing a mode of insulation constant-voltage conversion firstly and constant-current conversion secondly, and constant direct-current power supply is output to drive the LED lamp bead; and the smart sensor comprises a brightness sensor and a vehicle flow rate sensor. The smart LED street lamp provided by the invention has the beneficial effects that smart control can be realized for the LED street lamp; the opening and closing of the street lamp and the brightness degree of the street lamp can be controlled according to the degree of the external light rays and the using conditions of roads; and the energy-saving effect is more obvious, the power coefficient can reach more than 0.95 when the power supply works, and the efficiency reaches more than 90%.

Description

technical field [0001] The invention relates to the technical field of lighting fixtures, in particular to an intelligent LED street lamp. Background technique [0002] At present, the opening and closing of street lamps on both sides of urban roads is carried out by the management department through manual management switches. However, in the change of seasons, with the weather being sunny, cloudy, rainy and snowy, cloud conditions, and light conditions are different, the light is also different in various areas of the city. At this time, manual control will be more difficult. The accuracy of closing will be affected, which will reduce the utilization efficiency of street lights. In addition, the current general street lamp itself cannot adjust the brightness according to the usage of the road, and its usage effect will be affected to a certain extent. [0003] The emergence of high-power LED lighting devices has greatly improved the lighting conditions of street lamps. ...
