AI Technical Summary

Technical Problem

Existing LED lighting systems suffer from problems such as large coverage area, multiple equipment types, severe interference, and poor reliability in large venues when using wireless dimming control, while wired dimming control is complex to install and costly.

Method used

By adopting the method of carrying adjustment commands on the bus voltage, the light output parameters, including spectrum, light intensity, color temperature, etc., are identified and adjusted through the lamp-level power supply module. The adjustment type is distinguished by the preset threshold and hold time information of the bus voltage, and the light output is finely controlled by the control function.

Benefits of technology

It simplifies the system wiring structure and control architecture, improves the clarity of the adjustment logic and the system reliability, and is suitable for centralized power supply scenarios with multiple lamps connected in parallel. It is especially suitable for the fine-tuning of light output control in large-scale greenhouses and plant factories, and reduces costs.

Abstract

The invention discloses an LED lighting system with adjustable light output. The system comprises a power supply module and a plurality of LED lamp assemblies connected with the power supply module in parallel through connecting cables, and each assembly comprises a lamp-level power supply module. The module is configured to adjust the light output of the corresponding component according to an adjustment instruction carried in the connection cable bus voltage. The adjusting instruction comprises a light output parameter type instruction which is used for a lamp-level power supply module to identify a target light output parameter type and enter a corresponding adjusting and controlling mode; and the light output parameter control instruction is used for adjusting the target parameter according to the instruction in the identified regulation and control mode. The invention aims to realize effective adjustment and control of light output of the LED lighting system.
