Abstract

The utility model discloses an improved tube-lamp water-proof structure which comprises a PCB plate, an LED, a cylindrical lampshade and a lamp holder, wherein the bottom of the light emitting surface of the lampshade is provided with a convex rib which extends along the lampshade lengthways and is provided with a rectangular outline, and a through hole which is used for a conducting wire to pass through is arranged on the bottom surface of the rectangular convex rib at the bottom of the lampshade; a certain distance is spaced by the PCB plate and the bottom surface of the rectangular convex rib along the bottom of the lampshade so as to form space. Thus, the function of heat dissipation is performed, and a water-proof function is also performed further. The bottom surface of the rectangular convex rib is respectively provided with the through hole which is used for the conducting wire to pass through. The lower part of the cross section of the lamp holder forms a rectangular frame, and the upper part of the rectangular frame forms a U-shaped groove. One through hole which is used for the conducting wire to pass through is respectively arranged on both ends of the bottom surface of the U-shaped groove at the bottom of the lamp holder. The through holes are matched with the through hole which is arranged on the bottom surface of the rectangular convex rib on the bottom of the lampshade. One end cover is respectively arranged on both side surfaces of the lamp holder and the lampshade. The improved tube-lamp water-proof structure has the advantage of good water-proof effect.

Description

A kind of spot waterproof construction of improvement

Affiliated technical field

The utility model relates to a kind of spot waterproof construction of illumination and decoration device, particularly a kind of improvement.

Background technology

At present, the outdoor lighting decorative applications is very extensive, particularly be used for the spot of profile of decorative architecture exterior wall, the decorative effect of this spot is good especially, but because the waterproof construction of this product is difficult to solve fully always, so its waterproof effect also just becomes the main performance of judging this product, the Chinese patent publication number is CN2639699Y at disclosed patented product on September 8th, 2004: a kind of LED pipe die is intended neon light waterproof storage line structure, this invention has disclosed a kind of by on the bottom surface of circular lampshade and lamp socket a through hole being set respectively, and reach waterproof and fixing purpose at wiring place encapsulating water, but because circular lampshade and the contacted place of lamp socket are cambered surface, so be difficult to reach waterproof and fixing effect with screw thread and packing ring, and since between glue and lampshade and the lamp socket owing to the different degumming phenomenons that are easy to generate of material, thereby have the halfway defective of waterproof effect.

Summary of the invention

The purpose of this utility model is in order to overcome the defective of above-mentioned existence, a kind of spot waterproof construction of improvement of good water-proof effect to be provided.

The technical solution adopted in the utility model is a kind of spot waterproof construction of improvement to achieve these goals, mainly comprise: pcb board, LED, cylindrical lampshade, lamp socket, the bottom of described lampshade light-emitting area is provided with one along the rectangular convex tendon of the profile of lampshade longitudinal extension, the bottom of the section of described lamp socket is a rectangle frame, the top of rectangle frame is U type groove, the bottom surface of U type groove respectively is provided with the through hole that is used for by lead at the bottom of reaching lamp socket on the rectangle convex tendon of lampshade bottom, fix by cushion rubber between described power line and through hole are straight, respectively be provided with an end cap in the two sides of lamp socket and lampshade.

Described pcb board forms a space with keeping at a certain distance away along the rectangle convex tendon of lampshade bottom.The spot waterproof construction of a kind of improvement of the utility model compared with prior art its beneficial effect has: owing to be provided with one along the rectangular convex tendon of the profile of lampshade longitudinal extension in the bottom of lampshade light-emitting area, the both sides of its convex tendon are provided with a holddown groove that is complementary with lamp socket, and fix by cushion rubber between power line and through hole are straight, so this fixed form has the advantage of good water-proof effect.

Description of drawings

Fig. 2 is a blast structural representation of the present utility model;

Fig. 3 is the structural representation of lamp socket of the present utility model and lampshade;

The specific embodiment

Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail.

With reference to Fig. 1,2,3, the utility model comprises: pcb board 4, LED5, cylindrical lampshade 2, lamp socket 1, the bottom of described lampshade light-emitting area is provided with one along the rectangular convex tendon 21 of the profile of lampshade longitudinal extension, this lampshade is a printing opacity plastic opaque material, light-emitting area is a circular arc, be provided with the groove of inlaying pcb board in the pipe, the rectangle convex tendon bottom surface 22 of lampshade bottom is provided with a through hole 23 that is used for by lead, described PCB4 plate forms a space with keeping at a certain distance away along rectangle convex tendon 21 bottom surfaces 22 of lampshade 2 bottoms, thereby play the effect of heat radiation, also further play waterproof effect, in order to be that many fluorescent tubes are connected in series, so a through hole 23 that is used for by lead respectively is set in rectangle convex tendon 21 bottom surfaces 22.The bottom of the section of described lamp socket is a rectangle frame 11, the top of rectangle frame is U type groove 12, U type groove bottom two ends respectively are provided with a through hole 13 that is used for by lead at the bottom of lamp socket, the through hole 23 that is provided with on this through hole and the lampshade bottom rectangle convex tendon bottom surface 22 is complementary, and respectively is provided with two lead fixed mouths 16 in the both ends of the surface of the symmetry at rectangle frame 11 two ends.Be used to place controller in the described rectangle frame 11 and connect lead, for easy for installation, its in the bottom 15 of rectangle frame 11 for can be set to inserted plate, its plate can mount and dismount easily, during assembling with wire bonds to pcb board 4, pass the through hole 13 of U type groove bottom at the bottom of the through hole 23 of lampshade convex tendon 21 bottom surfaces and the lamp socket then, the fixing back of its lampshade and lamp socket is fixing by cushion rubber 6 then, because the stationary plane that lampshade of the prior art contacts with lamp socket is arc surface, so the time by the cushion rubber fixing cord, its cushion rubber is not easy to be fixed in the through hole, and the glue of smearing around cushion rubber is because of the different degumming phenomenons that occur easily with the material of contact-making surface, in order to solve the defective that exists in the prior art, adopt in the utility model and be provided with one along the rectangular convex tendon 21 of the profile of lampshade longitudinal extension in the bottom of lampshade light-emitting area, be provided with on the top of rectangle frame equally and be U type groove 12, because the stationary plane that lampshade contacts with lamp socket is the plane, so its lead can closely link together with lampshade and lamp socket by waterproof apron.In order to keep in repair and easy for installation, so respectively be provided with an

end cap

14,24 in the two sides of lamp socket 1 and lampshade 2.The utlity model has the advantage of good water-proof effect.

Above illustrated embodiment only in order to convenient explanation the utility model, is not breaking away from creation spirit category of the present utility model, is familiar with the various simple and easy covert and modification that the personage did of this technology, still should be included in the technical solution of the utility model scope.
