LED (Light-emitting diode) lamp tube electrode with easily determined LED polarity

Abstract

The invention relates to an LED lamp tube electrode with easily determined LED polarity. The LED lamp tube electrode at least comprises an LED lamp panel, a lamp panel heat dissipation rack, lamp holders at two ends and a lamp tube, wherein the LED lamp panel is fixed on the lamp panel heat dissipation rack; the LED lamp tube electrode is characterized in that the lamp tube is connected to the outer end of the lamp panel heat dissipation rack in a sleeving manner; the lamp holders at two ends are encapsulated at two ends of the lamp tube, and are used for enabling a left lamp tube electrode and a right lamp tube electrode which are connected with a power supply to extend out from two ends of the lamp holders; shapes or sizes the left lamp tube electrode and the right lamp tube electrode are different; the electrodes with different shapes or sizes form positive and negative electrodes, so that positive and negative electrodes are distinguished when the lamp tube is installed. The LED lamp tube electrode can greatly reduce the use quantity of aluminum heat dissipation racks, simplifies the production technology of LED lamp tubes, reduces labor cost, reduces the total cost of the LED lamp tube, does not need polarity conversion circuits, and has the characteristics of environment protection, efficiency saving and the like.

Description

[0001] This case is a divisional application for the application name "an LED lamp tube that can easily determine the polarity of the LED", the application date is 2013-8-6, and the application number is 2013103378385. technical field [0002] The invention relates to an LED lamp tube, in particular to an electrode of the LED lamp tube which can easily determine the polarity of the LED. Background technique [0003] Existing LED lamp tubes install the power supply and LED lamp board on the lamp tube heat sink at the same time, and one end leads out to the power socket. When using it, it only needs to be connected to a 220V or 110V power supply through the power socket. Due to the size of the LED lamp board and power supply 1. The power determines that the volume of the lamp tube heat sink should not be too small. The problem considered in this aspect is: on the one hand, it can be installed into the LED lamp tube and power supply, and at the same time, it can achieve the purp...

AI Technical Summary

Problems solved by technology

[0004] With the improvement of LED efficiency, the heat dissipation of the LED light board itself is getting smaller and smaller, and the optical power output is getting bigger and bigger. The only problem that exists is how to design a reasonable volume of the light tube cooling frame to reduce the overall cost of the light. , reduce the use of aluminum profiles, to achieve the purpose of saving energy and saving raw materials

[0006] Due to the structure of the existing LED lamp tube, its manufacturing process is complicated, especially the lead wires between the power supply and the lamp board, and the connection between the power supply and the lamp holders at both ends, which require manual operation for a long time. The increase will increase the cost of LED lamp tubes. Generally, the labor cost of a lamp tube is 2-3 yuan, which will greatly affect the sales price and eventually cause the market price to rise.

[0007] The applied patent discloses a kind of electrode of LED lamp tube which is easy to determine the polarity of LED. It separates the LED lamp tube from the power supply to the LED lamp tube. Problems with installation and use of non-polar tubes
