Detailed Description

As shown in fig. 1 and 2, an LED lamp tube includes a lamp tube 1, a lamp head 2 and a lamp strip 4, wherein the lamp head 2 is cylindrical and is sleeved with two ends of the lamp tube 1. The utility model discloses a fluorescent tube 1 is the non-pipe, and its cross sectional shape is excellent arc, and its part pipe wall is the plane, and lamp strip 4 is fixed on plane 12. Meanwhile, clamping grooves 13 are formed in two sides of the plane 12, the distance between the two clamping grooves 13 is matched with the width of the light bar 4, and the clamping grooves 13 press the light bar 4 to be attached and fixed to the plane 12.

The base 2 is likewise non-circular in cross-section and has a flat surface 21. The inner diameter of the base 2 corresponds to the outer diameter of the lamp vessel 1, leaving only a gap for assembly. In order to avoid the relative rotation between the lamp cap 2 and the lamp tube 1, the lamp tube 1 is provided with a fastening hole 11, and the inner wall of the corresponding lamp cap 2 is provided with a fastening point 22 which is clamped into the fastening hole 11. The fastening points 22 are barbs, so that the lamp tube 1 can be prevented from being withdrawn from the lamp holder 2. The utility model discloses only set up a set of knot point and detained the hole, the leading cause lies in that lamp holder 2 has plane 21.

The lamp strip 4 includes the base plate and welds a plurality of LED lamp pearls on the base plate, still is provided with drive power supply on the lamp strip 4 generally. When assembling, it needs to be electrically connected with the lamp pin 3 on the lamp holder 2 to realize electric conduction. The utility model discloses improved the equipment mode of traditional fluorescent tube, inside a set of public plug 6 and the female plug 5 of being provided with of LED fluorescent tube.
