Automatic power-off device and method for fluorescent lamp

Abstract

The present invention relates to an automatic power-off device for fluorescent lamps and a method thereof, comprising: a sensing module is arranged at a position close to the fluorescent lamp module to continuously detect the light signal of the fluorescent lamp module and its environment and send the light signal Converted into an electrical signal, defined as the signal to be detected; the calculation module is used to calculate the signal strength of the signal to be detected at a predetermined time after the fluorescent lamp module is powered on, defined as M0, and the calculation module continues to calculate the predetermined time The signal strength of the signal to be detected is defined as M1, and the value of M0 minus M1 is calculated, which is defined as D1, that is, M0-M1=D1; the setting module is used to set a preset value, which is defined as D0 ; and the control module is used to control the turn-on and cut-off of the power supply of the fluorescent lamp module; it is characterized in that: the calculation module judges the relationship between the D0 and the D1, if it is judged that the D0 is smaller than the D1, the control module cut the power.

Description

technical field [0001] The present invention relates to the field of lighting appliances, and more specifically relates to an automatic power-off device for fluorescent lamps and a method thereof that judges whether the fluorescent lamps flicker by sensing the intensity of the light signal emitted by the fluorescent lamps for a period of time and automatically cuts off the power. Background technique [0002] As one of the most commonly used lighting lamps in modern homes, fluorescent lamps are closely related to users' daily work and life. During the use of fluorescent lamps, sometimes due to a series of reasons such as lamp aging, internal circuit damage, starter internal capacitor damage, low temperature environment, etc., a certain lamp or multiple lamps inside the fluorescent lamp will flicker or dim. And other phenomena, causing certain troubles to the user's work or life. [0003] In the case of fluorescent lamp flickering, turn off the power switch, all the internal...
