Problems solved by technology

At present, the urban image illuminance is often several times the standard illuminance, far exceeding the national standard. When only the safe illuminance needs to be retained, a lot of energy is wasted.

specific Embodiment approach

[0037] Such as figure 1 As shown, it is a power saver disclosed by the embodiment of the present invention, which mainly includes: a first relay KA1, a first inductance L2, a first relay coil 101, a second relay KA2, a second inductance L3, a second relay A coil 102 , an MCU module 103 , a power supply module 104 , a power carrier module 105 , an acquisition module 106 and a drive module 107 .

[0038] The power supply module 104, the power carrier module 105, the collection module 106, and the drive module 107 are respectively connected with the MCU module 103, and the power supply module 104 receives the power grid ( figure 1 L in represents live line, N represents the voltage of AC AC220V ± 20% in zero line), and the received voltage is converted into the working voltage of MCU module 103, so that MCU module 103 works normally. The power carrier module 105 is used to send and receive power carrier signals. The power carrier module 105 receives the power carrier signal, de...

Abstract

The present invention discloses an electricity-saving device. The device comprises a first relay, a second relay, a first inductor and a second inductor connected in series, an MCU module, and a power module, an acquisition module, a power carrier module and a driving module which are connected with the MCU module. The first inductor is an overvoltage winding, and the second inductor is a power reduction winding; the power module supplies work voltage to the MCU module; and the power carrier module receives power carrier signals sent by a centralized controller, performs demodulation processing of the power carrier signals, sends the processed power carrier signals to the MCU module, receives feedback instructions fed back through the MCU module, converts the feedback instructions to power carrier signals, and sends the power carrier signals to the centralized controller through coupling the power carrier signals on an alternate current power line, wherein the feedback instructions are work state information of a current discharge lamp. The electricity-saving device is simple to operate and convenient for usage.

Description

technical field [0001] The invention relates to a power saver. Background technique [0002] With the continuous improvement of living standards, people's requirements for urban lighting environment are getting higher and higher. Not only safety lighting is needed, but also lighting that enhances the image of the city is added. Relevant departments stipulate that: during normal lighting hours, the illuminance specified in the standard should be reached, and in periods of no need for normal lighting (such as the second half of the night), only safe illuminance can be reserved, and its illuminance value is generally controlled at half of the standard. However, the current urban image illuminance is often several times the standard illuminance, far exceeding the national standard. When only the safe illuminance needs to be retained, a lot of energy is wasted. Therefore, it is inevitable to reduce the illuminance to a safe illuminance to achieve the purpose of energy saving dur...
