Description

light tube

technical field

The invention relates to the lamp tube, which aims to provide a design that can pass through the tube body, the circuit board and the end cap, so that the user can form a contact conduction with a simple plugging action, and is suitable for fluorescent lamps and energy-saving lamps Or a structural improvement similar to a light tube.

Background technique

Press, the tubes of early fluorescent lamps are mostly made of glass, and the fluorescent tubes contain a small amount of mercury, so you need to be extremely careful when handling or installing them, because if you accidentally break the fluorescent tubes, the mercury inside will flow out. The environment causes harm, and if the human body accidentally touches or absorbs it, it will also cause poisoning; and although traditional fluorescent lamps are cheap, their waste has disadvantages such as mercury pollution or fragility.

However, the new-generation improvement of the current fluorescent lamp uses light-emitting diodes (LEDs) to emit light, and its structure is also the same as the early fluorescent lamp design, so as to be suitable for the early lamp holders.

Please refer to FIG. 1 , pointing out that the structure of the conventional LED light tube mainly includes a hollow tube body 11 , a light emitting module 12 and two external modules 13 . The hollow tube body 11 includes a base body 110 and a lampshade 111 covering the base body. The light-emitting module 12 includes a circuit board 120 and a plurality of LEDs 121 combined on the circuit boards 120, and a circuit on the circuit board 120 is electrically connected to the LEDs 121. Lead block 123 . The two external modules 13 are combined at both ends of the hollow tube body 11 , and each external module includes an end cover 130 , a fixing block 131 and two terminals. The end cover 130 is coupled to the base body 110 by a bolt 133 , and the fixing block 131 is screwed to the base body 110 by the bolt 133 . The two terminals include an insert 136 and a guide post 137 . The embedded block 136 is embedded in the fixed block 131 with one side exposed from the bottom of the fixed block 131 , and is in solder contact with the outer conductive block 123 on the outer circuit board 120 . The guide post 137 extends from an end surface of the insert 136 and protrudes from the end cover 130 to the outside.

However, the disadvantages of the conventional technology are as follows. the

1. The assembly of the external module is complicated and the assembly cost is relatively high.

2. Welding quality is difficult to judge with the naked eye, so small cracks may occur, and if the level of welding personnel is uneven, it is easy to affect the welding quality.

3. Generally, LED lamp tubes still use the conventional lamp holder structure. When the LED lamp tube is inserted into the socket of the conventional lamp holder structure, it needs to be rotated 90 degrees before the power can be turned on. This will cause the irradiation surface of the LED lamp tube to deviate from the 90 degrees, so that the side below the LED tube cannot be illuminated.

Contents of the invention

The present invention is to provide a design that can pass through the tube body, circuit board and end cap, allowing users to form contact conduction with a simple plugging action, so that the circuit board and tube body can be rotated 360 degrees to adjust different The effect of the illumination angle, thereby increasing the overall practicality.

In order to achieve the purpose of exposing, the lamp tube of the present invention includes: a tube body, two end caps and a circuit board, a positioning groove is provided inside the tube body for setting the circuit board, and each end cap is respectively arranged on the two sides of the tube body. end, and two electrical terminals are respectively provided, and a conductive terminal is respectively provided on the inner side of each end cover, and the conductive terminal is connected to the electrical terminal, and a socket is provided at two ends of the circuit board; thereby, through each end The conductive terminal of the cover is directly plugged into the socket to form a contact conduction to conduct electricity, so that it has simple assembly, and the maintenance kit can be replaced by ordinary people, and the electrical connector has a 360-degree rotatable structure, which can form a tube body And the circuit board to rotate corresponding to the azimuth to adjust the required irradiation angle for use.
