Detailed ways

Below in conjunction with accompanying drawing the utility model is described in detail.

Referring to Fig. 1 to Fig. 4, a connecting end cap of a lamp tube includes an end cap body 1, one end of the end cap body 1 is an open end 11, and the other end of the end cap body 1 is a closed end 12, so The end cap body 1 includes a fixing part 2 and an inserting part 3 connected to the fixing part 2, the inserting part 3 is provided with a support 4 that can extend into the light pipe 6, and the closed end 12 is provided There are conductive terminals 5; the connection end cover of a lamp tube of the present utility model has a support 4 for supporting the light pipe 6, so when manufacturing, the light pipe 6 is sleeved on the support 4 The outside is convenient for positioning. At the same time, the support member 4 supports the end of the light pipe 6 inside. When it is fixed, it will cause damage to the end of the light pipe 6. In summary, the utility model has the advantages of stable connection and convenient assembly. At the same time, the light tube with this structure will not loosen between the light tube 6 and the connecting end cap due to external force, so the service life is long.

In this technical solution, the support member 4 includes a ring segment 41 and a semicircle segment 42 connected with the ring segment 41; generally speaking, the light pipe 6 generally has a circular cross section, so that the The end portion of light pipe 6 is sleeved on the outside of support member 4, when using LED etc. as light source, substrate must be installed in its connection end cover, the semicircle section 42 of this technical proposal has opening, like this, is conducive to the substrate Installing, at the same time, when the base plate is loaded, it is naturally stuck between the circular ring section 41 and the semicircular arc section 42, avoiding the method of adding screws or bonding, which is convenient for assembly. Of course, a further improvement is that: the two arc-shaped ends of the semi-circular arc segment 42 are provided with horizontal support bars 43, so that the support effect on the substrate is better and the assembly work is simpler.

In this technical solution, the conductive terminal 5 includes a fixed plate 51 and a conductive contact pin 52 arranged on the fixed plate 51, the closed end 12 is provided with a groove 13 for accommodating the fixed plate 51, and the groove 13 is provided with a through hole 14 through which the conductive contact pin 52 passes. Since the conductive terminal 5 of this technical solution is arranged in the groove 13, it is more reliable and safer to use than the exposed terminal of the prior art.

Usually, during the use of the lamp tube, the heat will cause the internal air to undergo thermal expansion and contraction changes, so in this technical solution, the closed end 12 is also provided with an air injection hole 15 for injecting gas into the light tube 6 , the gas injection hole 15 is equipped with a gas nozzle 16; the purpose of the gas nozzle 16 is to inject inert gas, such as nitrogen and argon, into the light tube 6 according to different lamp tubes, and the chemical properties of nitrogen are inactive. , can prevent the light pipe 6 from bursting due to thermal expansion and contraction, and the argon gas can change the color of the emitted light. In summary, this structure makes the work of charging and discharging gas easier and easy to operate.

In addition, in order to be more easily inserted into the light pipe 6 during assembly, the diameter a of the outer end of the support 4 is smaller than the diameter b of the inner end of the support 4; in this technical solution, obviously, the inner diameter of the support 4 The end diameter can be set to be equal to the diameter of the light pipe 6. When the outer end diameter a of the support member 4 is smaller than the inner end diameter b of the support member 4, the support member 4 actually forms a similar tapered column. When the light pipe 6 is loaded from the outer end of the support 4, it is relatively loose until it is relatively tightly installed on the inner end of the support 4; support.

Referring to Fig. 5 to Fig. 7, a lamp tube of the present utility model includes a light tube 6 and the above-mentioned two connection end caps, and the two connection end caps are respectively fixed at both ends of the light tube 6, and the two An LED substrate 7 is arranged between the connecting end caps, and several LED lamp beads 71 are arranged on the LED substrate 7; the lamp tube described in the utility model adopts the connecting end cap with the supporting member 4, so the light pipe 6 and the connection end are not easy to loosen, and the LED substrate 7 is clamped through the support member 4 on the connection end cover, without using screws or glue for fixing, which saves manufacturing costs.
