Embodiment 1

[0032] In the case of daily lighting, the second static contact of the first relay KA1 is closed, the first static contact of the second relay KA2 is closed, and then controlled by the MCU module 103, so that the first relay KA1 and the second relay KA2 are no longer action, let the current only pass through the standard inductance L1, so that the discharge lamp 108 works in the rated state.

Embodiment 2

[0034] When the line voltage is higher than 5% to 10% of the rated voltage 220V, the acquisition module 106 sends the collected voltage signal to the MCU module 103 after isolation protection, and the MCU module 103 makes a corresponding judgment according to the received voltage signal, and then The corresponding MCU command is generated and sent, and the drive module 107 receives the MCU command, drives the first relay KA1 to act, closes the first static contact of the first relay KA1, connects the first inductance L2 to the circuit, and makes the circuit The impedance of the discharge lamp increases, so that the operating current of the discharge lamp 108 falls within the rated range, which can prolong the service life of the discharge lamp 108 under high voltage working conditions, reduce the power consumption of the discharge lamp 108, and achieve the effect of energy saving and life extension.

Embodiment 3

[0036] When only the safety lighting is reserved or in the middle of the night or in a certain preset period, it is necessary to greatly reduce the working power of the discharge lamp. At this time, the power carrier module 105 receives the power carrier signal sent by the centralized controller, and The signal is demodulated, and then sent to the MCU module, the MCU module 103 generates the corresponding MCU command according to the demodulated power carrier signal, and then the drive module 107 receives the MCU command, and drives the second relay KA2 to act, so that the first The second static contact of the relay KA1 and the second static contact of the second relay KA2 are closed, causing the second inductance L3 to be connected to the line, so that the operating current of the discharge lamp 108 is greatly reduced, so that the active power consumed by the discharge lamp 108 The power is reduced, so as to reduce the power of the discharge lamp 108 and achieve the purpose of ...

Abstract

The invention discloses a power saving device, comprising a first relay, a second relay, a first inductor and a second inductor connected in series, an MCU module and a power supply module, an acquisition module, a power carrier module and a drive module which are respectively connected with the MCU module; the MCU module generates a corresponding MCU instruction according to the received and acquired voltage signals or power carrier signals, then the drive module receives the MCU instruction, drives all the relays to act according to the MCU instruction and accesses the inductors correspondingly connected with all the relays into a circuit or disconnects the inductors from the circuit so as to increase impedance in the circuit or reduce the working current of a discharge lamp in the circuit. The power saving device can solve the problems of short service life and more power consumption due to the discharge lamp working under high voltage in the prior art, thus achieving the effects needing to be realized by the invention, and also achieving the effects of saving power and prolonging the service life even if the discharge lamp is in the use process.

Description

technical field [0001] The invention relates to the field of power saving, and more specifically relates to a single-lamp intelligent 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 redu...
