Abstract
Description
Technical Field
[0001] This utility model belongs to the field of T8 lamp technology, specifically relating to a dimmable T8 lamp with an emergency function. Background Technology
[0002] T8 fluorescent tubes are a common type of lighting and decorative electrical appliance. They consist of a tube, end caps at both ends of the tube, and a light source board inside the tube. A power driver is fixed in one of the end caps, as shown in CN202021121149.2. While they can meet general usage needs, they have requirements for the input power supply. Specifically, the end cap with the power driver needs to be connected to the input power supply, which places high demands on assembly. Furthermore, conventional T8 fluorescent tubes cannot meet emergency lighting needs, thus affecting their applicability and limiting their stability, making it difficult to meet market demands.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example
[0023] See Figures 1 to 3As shown, a dimmable T8 lamp tube with emergency function includes a hollow tube body 1, two plugs 2 connected to the ends of the hollow tube body, conductive posts 3 fixedly installed on the plugs, a light source board 4 disposed inside the hollow tube body, and a drive circuit board 5 fixed inside one plug. In this embodiment, the hollow tube body and plugs are conventional structures of the prior art, wherein the outer diameter of the hollow tube body is the same as the inner diameter of the plug; the plugs are plastic structure plugs. The hollow tube body is a glass tube or a light-transmitting plastic tube. The light from the light source board can be emitted outward through the hollow tube body. Its drive circuit board is a conventional structure of the prior art, including a rectifier filter circuit and a transformer circuit. For convenient control, a dimming toggle switch 6 is provided on the drive circuit board. This allows for on / off control of the corresponding drive circuit board, improving ease of use.
