Traditional fluffy ceiling light includes substrate, lamp holder and lampshade, and substrate is installed on ceiling, and route is provided in lamp holder Plate and several conducting wires, the bottom surface of lamp holder are removably connected with LED pipe, and lamp holder is fixed on substrate, and lamp holder is located at substrate and lamp Between cover, lampshade is removably mounted on substrate.

And fluffy ceiling light is often installed on the offers illumination such as all kinds of offices, corridor, operation room, cabin, still, in fluffy ceiling light When being installed in cabin, since humidity is higher in cabin, enter in lampshade so as to cause a large amount of steam, so that wiring board is corroded, It may cause the fluffy ceiling light failure, the part steam in lampshade, which can liquefy, is in a liquid state and comes together in the bottom surface of lampshade, to influence Illuminating effect.

Utility model content

The purpose of the utility model is to provide a kind of fluffy ceiling lights of LED, improve whole leakproofness, so that it is fluffy to improve the LED The service life and illuminating effect of ceiling light.

The purpose of this utility model has the technical scheme that

A kind of fluffy ceiling light of LED, including substrate, lamp holder and lampshade, lamp holder are set between lampshade and substrate, and lamp holder is solid Due on the bottom surface of substrate, the top surface of lampshade offers the annular groove along lampshade circumferentially extending, is connected in annular groove along annular The elastic ring of slot circumferentially extending extends to the outside of annular groove at the top of elastic ring, and being provided on lamp holder keeps lampshade relatively fixed Limit assembly.

By adopting the above technical scheme, elastic ring is caught in annular groove, and keeps lampshade opposite under the action of limit assembly It is fixed in substrate, while the top surface of elastic ring and the bottom surface of substrate push against, and squeeze elastic ring, and then improve whole sealing Property, to reduce into the vapour quantity in lampshade, that is, improve the service life and illuminating effect of the fluffy ceiling light of the LED.

The utility model is further arranged to: annular rib, annular rib inner wall and substrate bottom surface shape are provided on substrate At a card slot, it is clamped at the top of card slot and lampshade.

By adopting the above technical scheme, by the way that annular rib is arranged, and a card slot is formed between annular rib and substrate.Work as lamp When the top of cover and the card slot are clamped, elastic ring is abutted with the bottom surface of substrate, and the inner wall of annular rib and the outer wall of lampshade support It connects, to extend into the path of steam in lampshade, to improve sealing effect, while the water droplet on substrate also being avoided to flow into lamp In cover.

The utility model is further arranged to: the bottom of annular rib is arranged with sealing shroud, is caught in card slot at the top of lampshade When, sealing shroud and lampshade outer wall are interference fitted.

By adopting the above technical scheme, by the way that sealing shroud is arranged, and work as lampshade and be caught in card slot, and in the effect of limit assembly When lower realization is fixed, the bottom surface of elastic ring and substrate is pushed against, and sealing shroud and lampshade outer wall are interference fitted, to have dual close The effect of envelope.

The utility model is further arranged to: sealing shroud several is circumferentially set along annular rib towards offering on the face of card slot The annular groove set, each annular groove are arranged in parallel.

By adopting the above technical scheme, by the way that annular groove is arranged, to increase the screen resilience of sealing ring, consequently facilitating lampshade card Enter or be detached from card slot, connects the efficiency of the lampshade installation of people's raising.

The utility model is further arranged to: the inner wall of lampshade is fixed with the water suction ring being circumferentially arranged along annular groove, water suction The top surface of ring is higher than lampshade top surface.

By adopting the above technical scheme, by setting water suction ring, when steam successively passes through gap, the elasticity of lampshade and sealing shroud Gap between circle and substrate under the action of absorbing water ring, absorbs steam into lampshade, and the ring that absorbs water is set to Close to the top of lampshade, so that the time of contact of absorb water ahead of time ring and steam, improves dry effect.

The utility model is further arranged to: limit assembly includes screw rod, the fixed block for being fixed on lamp holder bottom surface, fixed block Bottom surface offer threaded hole, lampshade offers the impenetrating mouth passed through for screw rod, and one end of screw rod is fixed with nut, and the other end is worn It crosses impenetrating mouth and is threadedly coupled with threaded hole.

By adopting the above technical scheme, lampshade is caught in card slot, at this time impenetrating mouth face threaded hole, by screw rod far from nut One end pass through and impenetrating mouth and be caught in threaded hole, then rotating screw cap to nut and lampshade push against, to realize lampshade and lamp holder Fixation, and the leakproofness of lampshade is kept to realize closing to impenetrating mouth by setting nut.

The utility model is further arranged to: nut is towards flexible pad is fixed on the face of screw rod, when lampshade is relative to base When plate is fixed, flexible pad is pushed against between lampshade and nut.

By adopting the above technical scheme, by the way that flexible pad is arranged, when install lampshade, flexible pad abutting in nut and lampshade it Between, to improve the sealing effect to impenetrating mouth；And flexible pad contacts with lampshade and replaces contact of the nut with lampshade, thus to lamp The scratch of cover.

The utility model is further arranged to: the outer wall of lampshade is fixed with the bulge loop being circumferentially arranged along impenetrating mouth, works as lampshade When fixed relative to substrate, bulge loop and flexible pad are pushed against.

By adopting the above technical scheme, by the way that bulge loop is arranged, when lampshade and fixed substrate, bulge loop and flexible pad are pushed against, from And improve the sealing effect to impenetrating mouth.

The utility model is further arranged to: being fixed on the outer wall of lampshade several convenient for hand-held mounting blocks.

By adopting the above technical scheme, by the way that mounting blocks are arranged, consequently facilitating staff holds mounting blocks, thus lamp of taking Cover, has the effect of easy disassembly.

In conclusion the advantageous effects of the utility model are as follows:

(1) elastic ring is caught in annular groove, and fixes lampshade relative to substrate under the action of limit assembly, simultaneously The top surface of elastic ring and the bottom surface of substrate push against, and then improve whole leakproofness, to improve the use of the fluffy ceiling light of the LED Service life and illuminating effect；

(2) by setting sealing shroud, when the abutting of the bottom surface of elastic ring and substrate, and sealing shroud is matched with interference outside lampshade It closes, to have the effect of dual-seal；

(3) under the action of absorbing water ring, steam is absorbed by setting water suction ring when steam enters in lampshade, and Water suction ring is disposed in proximity to the top of lampshade, so that the time of contact of absorb water ahead of time ring and steam, improves dry effect.
