FOUR WIRE-TO-TWO WIRE LAMP CONTROL SYSTEM AND MEHTOD

原文（中国語）

A four wire-to-two wire lamp control method includes: inputting R, G and B lamp control signals are to corresponding oscillators which are controlled to generate R, G and B oscillation signals; the three oscillation signals being amplified and then coupled into a composite signal which is superposed onto integrated electric power to obtain composite electric power that is transmitted by a two-wire system transmission module. In this way, transformation from a four-wire lamp system to a two-wire lamp system is realized. The composite signal and power are synchronously transmitted in the two-wire system, such that the system can approximately synchronously transmit the composite signal at a low delay, and the integrated electric power can still be transmitted continuously in case of a low duty cycle of the lamp control signals, thus satisfying the requirement for driving power of a lamp.
