The utility model discloses a sealing structure of an LED lighting fixture, comprising a lamp tube (1), end covers (2) installed at both ends of the lamp tube (1), and a sealing ring (3) provided between the end covers (2) and the lamp tube (1). A U-shaped groove is provided on the sealing ring (3), which is sleeved on the end of the lamp tube (1) and wraps the inner and outer walls of the lamp tube (1). Anti-slip and sealing annular protrusions (31) are provided on the inner and outer surfaces of the sealing ring (3) on one side of the outer wall of the lamp tube (1). A groove is provided in the end cover (2), and the groove on the end cover (2) wraps the sealing ring (3), and the annular protrusion (31) on the sealing ring (3) is in close contact with the inner wall of the end cover (2). The sealing ring (3) is made of silicone.
Description
[technical field]
The utility model relates to the LED lighting, especially the end cover sealing structure of LED lighting.
[background technology]
It all is to adopt glue directly end cap to be fixed on lamp tube end that existing LED lighting end cap is connected with fluorescent tube, although such way good sealing effect, but maintenance is made troubles, some need to adopt means of destruction end cap could be pulled down, whole like this LED lighting just might be destroyed, cause the wasting of resources, improved maintenance cost.
[utility model content]
In order to solve deficiency of the prior art, a kind of new hermetically-sealed construction is provided, make sealing convenient and for ease of maintenaince, reduce maintenance cost, the technical solution adopted in the utility model is:
A kind of LED lighting hermetically-sealed construction includes fluorescent tube, in described lamp tube ends end cap is installed, and is provided with sealing ring between end cap and fluorescent tube.
Replace original glue sealing with sealing ring, can guarantee like this dismounting that end cap and fluorescent tube can also repeat when keeping sealing, be convenient to maintenance, reduce maintenance cost.
Be provided with U-shaped groove at described sealing ring, U-shaped groove is enclosed within lamp tube end and the fluorescent tube inside and outside wall is wrapped.
Adopt the seal of this shape and structure, can guarantee that being connected firmly of seal and end cap is stable, can not come off because of dismounting, in installation process, can also make along with the propelling of end cap it more firmly be fastened on lamp tube end.
The surfaces externally and internally that is in tube outer wall one side at described sealing ring is equipped with the annular protrusion of on-slip and sealing.
Adopt annular protrusion can guarantee that end cap can landing and make sealing effectiveness better, end cap is connected more firm with fluorescent tube.
Be provided with groove in described end cap, and the groove on the end cap wraps sealing ring, the annular protrusion on the described sealing ring is close to the end cap inwall.
In end cap, be provided with groove sealing ring is wrapped, can guarantee that like this sealing effectiveness is better, whole LED lighting is connected more firm.
Described sealing ring material is silica gel.
Adopting silica gel material is that long service life can seal and reduce cost better owing to its good springiness.
Adopting the hermetically-sealed construction of above structure, is to keep in repair more in many ways just fast, has reduced maintenance cost, and makes and guarantee that sealing effectiveness is identical with the glue sealing effect.

[specific embodiment]
The LED lighting includes fluorescent tube 1 and end cap 2 as depicted in figs. 1 and 2, is provided with sealing ring 3 between described fluorescent tube 1 and the end cap 2.
1. as shown in Figure 4, be provided with U-shaped groove at described sealing ring 3, U-shaped groove is enclosed within fluorescent tube 1 end and fluorescent tube 1 inside and outside wall is wrapped, and also is provided with groove in the end cap 2, and the groove in the end cap 2 wraps sealing ring 3.Sealing ring 3 as shown in Figure 5 and Figure 6 is provided with annular protrusion 31 being in fluorescent tube 1 outer wall one side, annular protrusion 31 can prevent that sealing ring from coming off from fluorescent tube 1, guarantee that simultaneously sealing effectiveness is better between sealing ring 3 and the end cap 2, make end cap 2 connect more firmly difficult drop-off.Described sealing ring 3 materials are silica gel, for elastomeric material can make sealing effectiveness better like this, when sealing ring 3 is set in fluorescent tube 1 end, annular protrusion on the sealing ring 3 and fluorescent tube 1 close contact make its difficult drop-off, after end cap 2 is installed to lamp tube end, groove in the end cap 2 compresses sealing ring 3, annular protrusion 31 is attached on the surface of end cap 2 and fluorescent tube 1 more closely, better tightness is connected more firm, the degree of protection of described sealing ring is IP65.
Claims (5)
