Description

Technical Field

[0001] This utility model belongs to the field of LED driver power supply technology, specifically relating to a constant current LED driver power supply with remote control and power metering. Background Technology

[0002] With the popularization of LED lighting technology, LED lamps are widely used in various scenarios due to their advantages such as energy saving and long lifespan. The accurate measurement and efficient management of LED lamp energy consumption has gradually become one of the core needs of the industry.

[0003] Currently, most LED lights with energy metering functions rely on detecting the PWM (Pulse Width Modulation) signal output from the dimming port of the LED driver power supply. The power consumption of the light is calculated by using a preset relationship between the PWM pulse width and power. However, in actual operation, the PWM pulse width of the LED driver power supply is not absolutely linearly related to the actual input power of the LED light due to factors such as input voltage fluctuations, load changes, and temperature drift. This results in a large error in the energy calculation results, which cannot meet the requirements for metering accuracy. Therefore, there is an urgent need for a constant current LED driver power supply with remote control and energy metering to solve the above problems. Utility Model Content

[0004] In view of the problems mentioned above in the background technology, the purpose of this utility model is to provide a constant current LED driver power supply that can be remotely controlled and has power metering capabilities.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows: A constant current LED driver power supply with remote control and power metering includes a power sampling module, which is connected to a power metering module, which is connected to a wireless networking module, which is connected to a driver power control module, which is connected to a driver power module, and a power line connecting the power sampling module and the driver power module. The power sampling module has a power input terminal, and the driver power module has a power output terminal. The power sampling module includes an isolation protection circuit. The input terminal of the isolation protection circuit is connected to an AC current sampling circuit and an AC voltage sampling circuit, and the output terminal of the isolation protection circuit is connected to a sampling signal output circuit. The wireless networking module includes a Bluetooth MCU, which is connected to the power metering module. The Bluetooth MCU is connected to an antenna and a data interface circuit, and is connected to the power control module via a power control signal.

[0006] Furthermore, the power sampling module can be selected from either a shunt-type sampling module or a mutual inductance-type sampling module as needed. This structural design allows for precise DC or low-current measurements using the shunt-type sampling module, such as in laboratories and electronic equipment. The mutual inductance-type sampling module is suitable for high-voltage, high-current industrial scenarios. The complementary design of these two modules meets the needs of different applications. Furthermore, the energy metering module employs a high-precision dedicated energy metering chip. This structural design improves the accuracy of metering.

[0007] Furthermore, the wireless networking module can also be equipped with a Wi-Fi module as needed. This structural design enables remote wireless communication with the terminal.

[0008] Furthermore, the driver power supply control module can output 0-10V dimming signals and dedicated driver power supply control signals as needed. This structural design is compatible with various LED driver power supplies.

[0009] The beneficial effects of this utility model are as follows: By setting up an energy sampling module and an energy metering module, this utility model can accurately and in real time measure the power consumption, power, voltage, current and other power data of the LED driver power supply, which solves the problem of low energy metering accuracy of existing constant current LED driver power supplies. By setting up a wireless networking module, this utility model allows users to obtain power consumption data in real time through the terminal without going to the site, and clearly understand the actual energy consumption of the LED lamps, thus solving the problem that existing constant current LED driver power supplies cannot be remotely controlled.
