Embodiment Construction

[0018] The present invention is described in detail below in conjunction with accompanying drawing:

[0019] An automatic intelligent power-saving device for LED street lamps, comprising a power supply circuit 1, an LED drive circuit 2 connected to the power supply circuit 1, and an MCU controller 3, and multiple LED lamps 4 connected to the LED drive circuit 2. The MCU controller 3 is also connected with a wireless microwave detector 5 that can detect movement signals when people or vehicles pass by and send the signal to the MCU controller 3 to adjust the brightness of the multi-channel LED lamps 4 lights.

[0020] The use of LED as street lighting has higher efficiency than traditional high-pressure sodium lamps or high-pressure mercury lamps due to its photoelectric characteristics, which can significantly save energy. Because LEDs are powered by AC / DC stabilized voltage, which allows a wide power input range, lighting efficiency is not affected by grid voltage fluctuation...

Abstract

The invention relates to an automatic intelligent electricity-saving device for a light-emitting diode (LED) street lamp. The automatic intelligent electricity-saving device for the LED street lamp comprises a power circuit, and an LED driving circuit and a micro control unit (MCU) controller which are connected with the power circuit, wherein a plurality of LED lamps are connected to the LED driving circuit; and a wireless microwave detector which can detect signals when a person or a vehicle passes by, and can send the signals to the MCU controller so as to regulate brightness of the plurality of LED lamps is connected to the MCU controller. The invention aims to overcome defects of the prior art and provides the intelligent electricity-saving device for the LED street lamp, which has a good energy-saving effect.

Description

【Technical field】 [0001] The invention relates to an automatic intelligent power-saving device for LED street lamps. 【Background technique】 [0002] Street lamps are the main part of urban lighting projects. Although street lamps have changed from traditional light bulbs to LED lighting, LED street lamps only improve the conversion efficiency of electric energy to light energy. Adjustment, it is the same as the traditional street lamp, it is still illuminated according to the established mode, the lighting of this mode has the following defects: 1) because the traditional LED lamp generates a lot of heat, the temperature rises and the LED lamp is easy to burn out; 2) the traditional LED lamp No matter how the ambient light changes, whether there is an unmanned vehicle passing by, no matter whether the weather is sunny or foggy, there is only one brightness, which consumes a lot of energy. [0003] The present invention is made based on this situation. 【Content of inventio...
