The invention discloses an energy-saving street lamp, and relates to the field of urban road illumination. In order to solve the technical problem that in the case of an existing street lamp for urbanillumination, the power can not be automatically adjusted according to the field environment, so that the energy consumption is large, a scheme is adopted. According to the scheme, a circuit board isfixedly arranged in an upper lampshade, a control unit and a brightness detection sensor are welded on the upper surface of the circuit board, light emitting diodes are welded on the lower surface ofthe circuit board, object detection sensors are welded to the two sides of the lower surface of the circuit board correspondingly, a light passing hole is formed in the top of the upper lampshade, and the control unit is electrically connected with the brightness detection sensor, the object detection sensors and the light-emitting diodes correspondingly. The external light is acquired through the brightness detection sensor, then whether the condition of turning on the street lamp is met or not is judged, if yes, whether a moving object exists or not is judged through the object detection sensors, if yes, the light emitting diodes are controlled to be in a rated power state for working illumination, and if not, the light emitting diodes are controlled to be in a state of being lower thanthe rated power for illumination, through the technical scheme, electric energy can be greatly saved.
Description
technical field [0001] The invention relates to the field of urban road lighting, in particular to an energy-saving street lamp. Background technique [0002] Road lighting refers to the lighting set for roads and their ancillary facilities. It is used to improve the safety of vehicles driving and pedestrians walking at night and prevent traffic accidents. Reasonable settings can improve traffic conditions, reduce driving fatigue, increase road capacity, and effectively reduce traffic accidents. Urban road lighting is an important part of urban public facilities, and with the advancement of urbanization, the number of urban road lighting street lights is increasing, energy consumption is getting higher and higher, and power supply tends to be tense. From 2004 to 2014, the number of urban road lighting lamps in my country has increased from 10.5315 million to more than 30 million, with an average annual compound growth rate of more than 11%. The urban road lighting industry...
