Description

    BACKGROUND OF INVENTION 1. Field of the Invention
  • The present invention relates generally to an improved structure, and more particularly to an improved structure of LED tube.
    • 2. Description of Related Art
  • In the internal structure of a conventional LED tube with power inlet on both sides, the base plate is adhered with a plurality of LED chips, one side of the base plate is welded with a driver having a plurality of electronic components, the two sides of the LED tube are respectively adhered with a cap having two plug pins on the outer side for power inlet, and two pairs of wires are used to respectively connect the driver with the adjacent cap and the plug pins adjacent to the other end of the base plate, the wires being respectively welded to the driver and inside the adjacent plug pins and the plug pins adjacent to the other end of the base plate. Because the driver often fails to start due to damage of the capacitor, the driver is adhered on the one side of the surface of the base plate, and the caps are adhered on the two sides of the LED tube, the LED tube cannot be dismantled for repair and is usually discarded, causing waste of materials and increased amount of garbage. This is not an environment-friendly practice. Moreover, the driver welded on one side of the surface of the base plate of the conventional LED tube occupies a space, and this position provides no space for welding multiple LED chips. Due to lack of LED chips, this position of the base plate is dark and has no light. This will affect the brightness of the LED tube. An LED tube with power inlet on one side has the same problem. This problem greatly affects the practicability of the product. Therefore, it is an aim of those skilled in the art as well as the consumers to overcome this problem.
    • SUMMARY OF THE INVENTION
  • To overcome the technical problem of the prior art, the main object of the present invention is to provide an improved structure of LED tube, wherein the two sides of the driver placed on the lower end of the base plate are configured with an outside connector and an inside connector connected via the wires, one side of the LED tube is provided with a cap having plug pins in parallel connection, the inside of the plug pins is connected with the wire with its outer end having an internal connector. This structure aims to solve the problem in the prior art.
  • A secondary object of the present invention is to provide an improved structure of LED tube, wherein the inside of the cap of the LED tube has individual independent plug pins connected with the wires, respectively having the internal connectors.
  • A third object of the present invention is to provide an improved structure of LED tube, wherein the driver is placed on the lower end of the base plate and the inside connector is connected to the lateral head on one side of the base plate, and the outside connector of the driver is connected with the internal connector of the cap.
  • A further object of the present invention is to provide an improved structure of LED tube, wherein the internal connectors inside the cap are independently connected to the two wires of the plug pins, and are respectively connected to the two outside connectors on one side of the driver connected via the wires, the other side of the driver is configured with an inside connector connected via two wires, the inside connector is connected to the lateral head on one side of the base plate that has multiple layers to produce a circuit. Or, the two internal connectors inside the cap are changed into two metal pins to be inserted into the outside connectors of the driver.
  • A further object of the present invention is to provide an improved structure of LED tube to effectively enhance the brightness. In this design, the driver will not block the LED chips and can be detached at any time for easy and fast repair in case of failure.
  • The present invention aims to solve the problems of the prior-art LED tube with its two sides respectively attached with a cap using adhesive and the outer side of the cap configured with plug pins for power inlet. Because the base plate is adhered with a plurality of LED chips, one side of the base plate is welded with the driver having a plurality of electronic components, and two groups of two wires or two groups of one wire are respectively welded between the driver and the adjacent plug pins, and between the base plate on the other end and the adjacent the plug pins, or respectively welded between the driver and the two plug pins configured on the other end of the base plate, the driver may often be damaged and cannot start. Because the driver is adhered on one side of the surface of the base plate, and the caps are adhered to the two sides of the LED tube, the LED tube cannot be disassembled for repair and is usually discarded directly in case of failure. This causes material waste and increased amount of garbage and is therefore not environment-friendly. Moreover, in the prior art, the one side of the surface of the base plate is welded with the driver that occupies a space. As a result, this position cannot be welded with a plurality of the LED chips. The place of the base plate without the LED chips will become dark, thus affecting the brightness of the LED tube and greatly reducing the practical value.
