Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] figure 1 Schematically shows the principle structure of the preferred embodiment 1 of the present invention, as figure 1 As shown, the preferred embodiment one includes a rectifier circuit, a light string module, a capacitor C1, an inductor L1 and two lamp caps A and B. Wherein, the rectifier circuit is used for current conversion, which is a bridge rectifier circuit formed by connecting diodes D1, D2, D3, and D4. One input end of the rectifier circuit is connected to the lamp cap A, and the other input end is connected to the capacitor C1, the inductor L1 and the lamp cap B in sequence. A light string module includes multiple LEDs connected together. In this preferred embodiment 1, 1 to M (an integer greater than 1) LEDs are first connected in parallel to form a parallel light string, and then 1 to N (an integer greater tha...

Abstract

The invention provides a ballast matched light-emitting diode (LED) general light tube. The ballast matched LED general light tube comprises a rectifying circuit, a light string module, a first capacitor and two light caps. The rectifying circuit is used for converting current. The light string module comprises a plurality of LEDs which are connected together. Two input ends of the light string module are connected with two output ends of the rectifying circuit. One end of the first capacitor is connected with one input end of the rectifying circuit. The two light caps are respectively connected with the other input end of the rectifying circuit and the other end of the first capacitor. The two light caps are used for receiving output of a ballast. The ballast matched LED general light tube can directly replace an existing fluorescent light tube without changing the structure of an existing ballast, and operation is fast. Besides, the ballast matched LED general light tube further has the advantages of being simple in structure, low in cost, and beneficial for larger-scale commercial use of the green and environment-friendly LED light tube.

Description

[0001] technical field [0002] The invention relates to an LED lamp tube, in particular to a general-purpose LED lamp tube which can be matched with an electronic ballast or an inductive ballast and can be directly applied to commercial power. [0003] Background technique [0004] LED has been widely used rapidly due to its energy saving and environmental protection characteristics. Before the large-scale application of LEDs in lighting, fluorescent lamps were widely used. Under the background that LEDs are increasingly valued, how to quickly replace fluorescent tubes with LEDs has become the focus of the industry. When replacing the current LED lamp tube with the fluorescent lamp tube, the original ballast must be dismantled and re-wired. The technical difficulty is relatively large, and the operation is relatively complicated, which is beyond what ordinary users can do. Therefore, large-scale LED lamp tubes Commercial use has obvious constraints. [0005] Contents o...
