Problems solved by technology

[0003] This type of production process in the prior art has many steps, time-consuming production and low production capacity
And in the assembly process, the interior of the lamp head is a visual blind spot, and the insulating rubber wire is easy to break the insulating rubber of the wire at the joint between the lamp head and the aluminum groove, causing the wire to be connected to the metal shell
This will bring the possibility of electric shock to users and product manufacturers, and there is a certain potential safety hazard.

Embodiment Construction

[0016] In order to further illustrate the principle and structure of the present invention, preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0017] The LED fluorescent lamp of the present invention adopts a metal plug-in form for the input connection structure of the AC working voltage input to the LED fluorescent lamp, which is different from the traditional power supply mode of connecting insulating rubber wires.

[0018] Newly designed conductive electrode pin 3 on the lamp cap 2 of the LED fluorescent lamp of the present invention, the length of the inner end of the electrode pin 3 in the lamp cap 2 is lengthened, and the electrode pin 3 is fixed on the lamp cap 2 through an injection molding process. The inner ends of the two electrode pins 3 are respectively closely connected with the conductive metal shrapnel 5 of the connecting terminals (L, N) on the PCB circuit board 4 in the lamp tube 1 to p...

Abstract

The invention provides an LED fluorescent lamp. The LED fluorescent lamp comprises a lamp tube, lamp caps at the two ends of the lamp tube, electrode needles on the lamp caps, and a circuit board inside the lamp tube. The circuit board is provided with elastic metal sheets connected with the electrode needles, the inner ends of the electrode needles are inserted in the elastic metal sheets in a penetrating mode, and the elastic metal sheets are attached to the circuit board. The LED fluorescent lamp is simple and convenient to assemble, and saves the labor cost. The electrical safety is high, and the phenomenon that the potential safety hazards are caused when a conventional electrode needle is connected with the circuit board through a wire, the lamp caps press the wire, and then the wire is broken, or the wire is damaged manually and makes contact with a metal case can be avoided.

Description

technical field [0001] The invention belongs to the technical field of lighting, and relates to an LED lighting device, and more specifically relates to a connection structure in an LED fluorescent tube. Background technique [0002] At present, in the LED industry, for the connection method of the input AC working voltage of the LED fluorescent tube, the insulated rubber wire is generally used to connect the input. The connection method is to weld two wires of different colors to the lamp holder of the lamp and the power supply terminal of the PCB circuit board respectively. (L, N) on. [0003] This type of production process in the prior art has many steps, time-consuming production and low production capacity. And in the assembly process, the interior of the lamp cap is a visual blind spot, and the insulating rubber wire is easy to break the insulating rubber of the wire at the joint between the lamp cap and the aluminum groove, so that the wire is connected to the metal...
