The invention discloses an LED fluorescent lamp circuit having an induction switch. The LED fluorescent lamp circuit comprises a controller, a sensor, a pre-stage amplifier connected with the sensor, a secondary frequency selection amplifier connected with the pre-stage amplifier, a voltage comparator connected with the secondary frequency selection amplifier, a zero cross detection circuit connected with the controller, a time-delay timer, a bidirectional silicon controlled rectifier used for connecting an LED fluorescent lamp, a light sensing unit used for detecting brightness of a surrounding environment of the LED fluorescent lamp in real time and an A / D converter respectively connected with the light sensing unit and the controller. The LED fluorescent lamp has properties of reasonable design and simple wiring; the LED illumination circuit having an induction function is employed, so whether human or vehicle movement occurs in the present environment can be automatically identified to determine whether to turn on the LED fluorescent lamp, automatic time-delay quenching is realized after a human body or a heat source leaves, and convenience and energy saving are both realized; an overheating protection function is further realized, and the LED fluorescent lamp is especially suitable for occasions requiring long-time illumination and having a few of passing-by people or vehicles.
Description
technical field [0001] The invention relates to a fluorescent lamp circuit, in particular to an LED fluorescent lamp circuit with an induction switch. Background technique [0002] Since the late 1960s, when gallium arsenide basically used phosphide to invent the first visible infrared LED, with breakthroughs in semiconductor and LED packaging technologies, the power levels of single-chip red, green, blue, and white LEDs And the brightness is continuously improved. With the obvious improvement of LED light efficiency, lifespan and light color, it has great potential in the fields of display, backlight, decoration and lighting. The application level of LED continues to expand, and its lifespan and luminous efficiency are higher than traditional lighting. At present, the main problem faced by LED in the field of lighting is the problem of intelligent control. The traditional LED fluorescent tube is mainly to keep the fluorescent tube fully lit after the fluorescent tube is p...
