Abstract

A lamp duplexing protection apparatus comprises a first lamp module and a second lamp module. The first lamp module outputs a first decision signal according to whether the first lamp operates normally. The second lamp module outputs a second decision signal according to an operating status of the second lamp. The first lamp module determines whether to supply power to the first lamp according to the second decision signal. The second lamp module determines whether to supply power to the second lamp according to the first decision signal.

Description

technical field

[0001] The present invention relates to a power supply for a lighting device and its operating method, and in particular to a power supply linkage operating device and its operating method. Background technique

[0002] Due to the popularization and application of liquid crystal displays, fluorescent lamps (Fluorescent Lamp, FL for short) have been widely used in the backlight system of liquid crystal displays (LCD for short), because fluorescent lamps have higher luminous efficiency and service life than traditional fluorescent lamps , and with the maturity of liquid crystal display technology and continuous breakthroughs in product quantification technology, and because liquid crystal displays continue to develop towards large sizes, the application of multi-lamp tubes is gradually moving towards a more complex direction.

[0003] Due to the application system of multiple light-emitting devices, multiple power supplies (each of which includes its own contro...
