Problems solved by technology

[0002] At present, the lamp tubes widely used in the market are basically thyristor dimming, 2.4G remote dimming, etc. These types of dimming methods cannot be directly used on the base with electronic ballasts, so they cannot directly replace the previous ones. Old product, poor compatibility
In addition, for occasions where a large amount of lamp tubes are used, such as warehouses and large-scale manufacturing workshops, if silicon controlled rectifiers are used for dimming, one dimmer can only control less than 10 lights, and many dimmers need to be installed; if If you choose remote control dimming, it will be limited by the remote control distance of the remote control, and the dimming is inconvenient

Abstract

The invention relates to a dimming lamp tube compatible with an electronic ballast. The dimming lamp tube comprises a full-wave rectifying unit, a low-frequency filtering unit, a driving unit, a control unit, a constant-voltage output unit and an LED lamp set. The full-wave rectifying unit comprises a capacitor C0, a first power supply interface end and a second power supply interface end. A zeroline interface N2 of the second power supply interface end and a live line interface L1 of the first power supply interface end are connected with two ends of the capacitor C0. When the dimming lamp tube is installed on a lamp holder with the electronic ballast, the electronic ballast and the capacitor C0 form a LC resonance, and the dimming lamp tube can work normally when a proper resonance point is reached. When a switch is pressed to switch on and off the power supply, the control unit memorizes the state before power failure to realize dimming, a dimming range is large, and convenience and quickness are realized. According to the invention, the transformation or replacement cost of the original lamp holder is saved, the application places are greatly expanded, and the lamp tube has more advantages especially in places where a large number of lamp tubes are used.
