Abstract
The utility model discloses an LED lamp tube based on a traditional electronic ballast. The LED lamp tube comprises the electronic ballast and an LED lamp set and is characterized in that the output end of the electronic ballast is connected with a capacitor C1 in series and then connected with the input end of a bridge rectifier, and the output end of the bridge rectifier is connected with a capacitor C2 in parallel then connected with the power end of the LED lamp set. The LED lamp tube based on the traditional electronic ballast has the advantages that a stable voltage is output from an LED lamp tube circuit through an LC resonance circuit and a full-bridge rectifier to drive an LED lamp to illuminate. The capacitor C1 is a capacitor C in the LC resonance circuit, and an inductor L is arranged in the electronic ballast. High-frequency high voltages are transmitted into the full-bridge rectifier through the capacitor C1, and a diode D1, a diode D2, a diode D3 and a diode D4 are fast recovery diodes. The high-frequency high voltages are rectified into stable direct voltages for the LED lamp set to use, the electronic rectifier in a traditional fluorescent tube is fully utilized, and therefore the electronic rectifier is not abandoned to cause resource waste.
Description
Technical field
The utility model relates to a kind of lighting apparatus, a kind of LED fluorescent tube based on conventional electronic ballast that specifically a kind of directly replace fluorescent lamps light pipe uses.
Background technology
LED fluorescent tube is also commonly called as LED light pipe, LED fluorescent tube, LED fluorescent lamp, and its light source adopts LED as illuminator.Traditional fluorescent tube claims again fluorescent lamp, and respectively there is a filament at lamp two ends, is filled with micro-argon and thin mercury vapour in fluorescent tube, scribbles fluorescent material on tube inner wall, when gaseous conduction between two filaments, sends ultraviolet ray, makes fluorescent material send visible ray.Owing to containing heavy metal pollutants " mercury ", make the fluorescent tube scrapped very serious to the pollution of environment.And LED fluorescent tube adopts light emitting diode as light source, light efficiency is higher, more energy-conservation, longer service life, and more environmental protection.Become the ideal product that the current stage replaces fluorescent tube.LED fluorescent tube is all the same on overall dimensions bore with traditional fluorescent lamp, there is T5 pipe, T8 pipe, T10 pipe, but existing fluorescent tube use amount is far longer than the use amount of LED fluorescent tube, if it is quite loaded down with trivial details that all fluorescent lamps are all replaced with to the whole process of LED fluorescent tube, original fluorescent lamp need to be taken off and changes LED fluorescent tube, and ballast and starter are removed, allow 220V electric main directly be added to LED lamp tube ends.But this structure needs LED fluorescent tube self to be equipped with transformer and other electronic circuits, and the rectifier using in conventional fluorescent fluorescent tube will be wasted, and contrasts with regard to energy resources aspect, and its energy-saving significance is also little.
Utility model content
The purpose of this utility model is the shortcoming existing in order to overcome prior art, provides a kind of simple in structure, easy to use, is not changing a kind of LED fluorescent tube of being replaced on the basis of discarded conditional electronic rectifier.
The utility model object realizes with the following methods: a kind of LED fluorescent tube based on conventional electronic ballast, it comprises electric ballast and LED lamp group, it is characterized in that: the output of described electric ballast is connected with the input of bridge rectifier with after capacitor C 1 series connection, after the output shunt capacitance C2 of described bridge rectifier, is connected with the power end of LED lamp group.
