LED (Light Emitting Diode) street lamp capable of following irradiation

Abstract

The invention belongs to the technical field of LED (Light Emitting Diode) lighting, and relates to an LED street lamp capable of following irradiation. The LED street lamp comprises an LED lighting assembly, a straight following driving mechanism, a steering following driving mechanism and a control device, wherein the LED lighting assembly comprises a lamp housing and an LED lamp panel, the straight following driving mechanism comprises a swing assembly and a limiting assembly, the steering following driving mechanism comprises a support frame and a driving assembly which is used for drivingthe support frame to rotate around a vertical direction, the control device comprises a controller and a detection assembly which is used for detecting a passerby, and the detection assembly is electrically connected with the controller. The intelligent following irradiation is realized, the structure of the street lamp is simplified, additionally, the range of irradiation of the LED lamp panel is enlarged, and irradiation can be specified according to pedestrians, so that more power is saved, and the lighting utilization rate is increased.

Description

technical field [0001] The invention belongs to the technical field of LED lighting, in particular, the invention relates to an LED street lamp capable of following illumination. Background technique [0002] At present, many street lamps are inconvenient to adjust the position of the lamp head in practical applications. The intensity of manual adjustment is high, so the practicability is not high, and it can only illuminate fixed positions, the irradiation area is fixed, and the lighting utilization rate is low. It can only be used for pedestrians. It plays a short-term lighting effect, and the lighting efficiency is low. [0003] In order to solve the above problems, the patent No. CN201710818382.2 is disclosed, which includes a lamp cap, a street lamp pole, a rotating head fixing seat and a driving motor. The upper end of the light pole, and the rotating shaft of the drive motor drives the rotating fixed seat to rotate freely relative to the street lamp. The lamp head is...

Problems solved by technology

[0002] At present, many street lamps are inconvenient to adjust the position of the lamp head in practical applications. The intensity of manual adjustment is high, so the practicability is not high, and it can only illuminate fixed positions, the irradiation area is fixed, and the lighting utilization rate is low. It can only be used for pedestrians. It plays a short-term lighting effect, and the lighting efficiency is low

[0003] In order to solve the above problems, the patent No. CN201710818382.2 is disclosed, which includes a lamp cap, a street lamp pole, a rotating head fixing seat and a driving motor. The upper end of the light pole, and the rotating shaft of the drive motor drives the rotating fixed seat to rotate freely relative to the street lamp. The lamp head is connected and fixed on the lower parts of both sides of the rotating head fixed seat through a connecting rod. The control switch for motor operation, multiple lamp heads can rotate freely on the upper end of the street lamp pole, but the intelligence is low, and it is not possible to specify illumination for pedestrians. There are many lamp heads, and the cost of street lamps is high. The motor drives the lamp head to continue to rotate, and the waste is relatively large. more electricity
