Abstract
The utility model discloses a contour lamp, which is mainly characterized in that a flexible sealing membrane is fixed near the end cover in the strip lamp. The flexible sealing membrane can generate elastic deformation with the heat expansion and cold contraction of the air in the strip lamp and make the internal and external pressure of the strip lamp basically same, so the sealing property between the sealing membrane and the strip lamp can still be kept after long time using, and the crack of the strip lamp which is caused by the large pressure of the air in the strip lamp is avoided.
Description
Technical field
The utility model relates to ornament lamp, particularly the structure of clearance light.
Background technology
Clearance light has a fluorescent tube, and lamp tube ends is stamped end cap.Because the effect that the air in the fluorescent tube expands with heat and contract with cold, after long-time the use, the sealing between fluorescent tube and the end cap will be damaged, if the environment for use temperature of clearance light is higher, even also can cause fluorescent tube to crack.The problem that therefore existing clearance light ubiquity sealing is poor, service life is short.
Summary of the invention
The purpose of this utility model provides a kind of influence that not expanded with heat and contract with cold by the air in the fluorescent tube, the clearance light with good seal performance.
The utility model is achieved in that clearance light comprises a fluorescent tube, and lamp tube ends is stamped end cap, and especially, the position near end cap in fluorescent tube is fixed with soft sealing film.Because soft sealing film plays sealing function, therefore the utility model no longer relies on end cap to seal, and owing to soft sealing film can be expanded with heat and contract with cold along with the air in the fluorescent tube strain is taken place, the inside and outside pressure of fluorescent tube is consistent substantially, still can keeps the excellent sealing between diaphragm seal and the fluorescent tube after therefore long-time the use.
The utility model has the advantages that not only have good seal performance, and can avoid having prolonged the service life of fluorescent tube because of the excessive shortcoming that causes fluorescent tube to crack of the expansion of the air in the fluorescent tube.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
Referring to Fig. 1, clearance light comprises a fluorescent tube 1, and lamp tube ends is stamped end cap 2, and the position near end cap in fluorescent tube is fixed with soft sealing film 3.Soft sealing film can be made with silica gel.When the air expanded by heating in the fluorescent tube 1, diaphragm seal 3 is heaved towards the direction of end cap 2, when the air cooling-down in the fluorescent tube 1 shrank, diaphragm seal 3 caved in towards the direction in the fluorescent tube, and this strain effect of diaphragm seal 3 is consistent the inside and outside pressure of fluorescent tube 1 substantially.
As further improvement, present embodiment also has air-vent 4 on end cap 2.Can avoid too tight like this, cause to form one deck mattress between end cap 2 and the diaphragm seal 3, hinder the Free Transform of diaphragm seal 3 because of connecting between end cap 2 and the fluorescent tube 1.
As preferred forms, the periphery of the soft sealing film 3 of present embodiment is outwards routed up the port edge that is wrapped in fluorescent tube 1.This fixed form of diaphragm seal was both implemented easily, can guarantee to have good sealing property between diaphragm seal and the fluorescent tube again.
Further, present embodiment is provided with annular gauffer 3a also as shown in Figure 1 and Figure 2 on soft sealing film.Annular gauffer 3a makes diaphragm seal have better elasticity.
Claims (4)
1, a kind of clearance light comprises a fluorescent tube, and lamp tube ends is stamped end cap, it is characterized in that: the position near end cap in fluorescent tube is fixed with soft sealing film.
2, clearance light as claimed in claim 1 is characterized in that: have air-vent on the end cap.
3, clearance light as claimed in claim 1 or 2 is characterized in that: the periphery of soft sealing film is outwards routed up the port edge that is wrapped in fluorescent tube.
4, clearance light as claimed in claim 1 is characterized in that: soft sealing film is provided with annular gauffer.
