A kind of led lamp tube and digital control method thereof

Abstract

The invention discloses an LED lamp tube and a digital control method thereof. A first photoelectric transceiver is installed on the lamp frame of the LED lamp tube, and a second photoelectric transceiver is installed on the lamp body. The position of the first photoelectric transceiver is the same as that of the second photoelectric transceiver. The positions of the two photoelectric transceivers are opposite, the lighting control system sends instructions to the first photoelectric transceiver through the control bus, and the first photoelectric transceiver transmits the received instructions to the second photoelectric transceiver through the non-contact transmission method of optical communication; The second photoelectric transceiver converts the received optical signal into an electrical command signal and transmits it to the LED drive control circuit; the LED drive control circuit interprets and operates the received electrical command signal to realize the digital control of the LED drive control circuit and solve the problem It solves the problem that the LED lamp tube has a single control method and cannot exchange data with the lighting control system, and there is no need to change the current standard of the joints at both ends of the LED lamp tube and the usage habits of installation and disassembly.

Description

technical field [0001] The invention relates to the field of LED lamp tubes, in particular to an LED lamp tube capable of flexibly monitoring the circuit inside the LED lamp tube through digital coded communication and a digital control method thereof. Background technique [0002] LED lamps use LEDs as light sources, which have the characteristics of high luminous efficiency, less power consumption, long service life, short response time, and environmental protection. The LED light tube is composed of a light frame and a light tube body. In order to be compatible with the long-standing usage habits, the current LED light tube adopts the same standard interface as the traditional fluorescent light tube, and the connectors at both ends of the light tube are generally designed to be directly connected to the mains. Therefore, its control mode is only a switch type or a phase-cut dimming mode of a power supply circuit. [0003] Switching control can only turn on and off the LE...

AI Technical Summary

Problems solved by technology

[0004] The main purpose of the present invention is to provide a multi-channel LED light source that can be independently controlled without changing the joints at both ends of the LED tube, which can be directly connected to the mains and without changing the installation and disassembly of the LED tube and the use habits and convenience. , and can exchange data with the lighting control system, the LED lamp and its digital control method are designed to effectively solve the problem of the single control method of the current LED lamp, the single color of the LED lamp and the inability to exchange data with the lighting control system. And other issues
