A kind of both-end LED tubular lamp with hermetically-sealed construction, comprise heat-dissipation aluminum sectional material and LED illuminating module, LED illuminating module is located on heat-dissipation aluminum sectional material, also comprise double-colored PC to manage, plug and sealing ring, it is inner that LED illuminating module and heat-dissipation aluminum sectional material are located at double-colored PC pipe, double-colored PC pipe comprises light-emitting area and the back side, the two ends of double-colored PC pipe are connected with a plug respectively, plug comprises hypomere and epimere, the diameter of hypomere is greater than the diameter of epimere, step-like in one, the inner side of plug hypomere and epimere junction is also provided with a groove, a sealing ring is provided with in groove, the gap that pipe end in order to seal plug and double-colored PC pipe produces time supporting.

Described double-colored PC pipe light-emitting area angle is 220 °.

Described plug is also provided with screw, in screw, is provided with screw, in order to be connected with heat-dissipation aluminum sectional material and to fix.

Also waterproof plug is provided with in described screw.

In technique scheme, the utility model has following advantage:

1. the utility model shell adopts overall plastic structural member, and LED module etc. may be sealed into entirety in charged position, safe and reliable when guaranteeing to use.

2. the utility model adopts rubber seal to replace silica gel, overturn with silica gel firming body interstitital texture part mechanical clearance and realized hermetic water-proof structure designing technique, well overcome existing fluorescent tube to be adhesively fixed the gluing inequality that technique occurs with silica gel owing to adopting between PC two-colour tube and plug, the undesirable defect of waterproof sealing performance.

3. the utility model adopts rubber seal to replace between silica gel PC two-colour tube and plug to be adhesively fixed technique with silica gel, to smear silica gel technique, eliminate silica gel curing process without the need to manual, mass can be realized, the large production of continuous productive process, thus reduce manufacturing cost, increase economic efficiency.

4. the performance of material that rubber seal of the present utility model adopts has anti acid alkali performance, high temperature resistant physics of Denging, chemistry, is much better than silica gel, overcomes silica gel premature ageing defect, greatly extend the service life of its fluorescent tube.
