Description

A kind of waterproof sealing structure of LED

Technical field

This utility model relates to a kind of novel LED waterproof sealing structure.

Background technology

Rechargeable LED lamp is widely used in the field such as daily life and commercial production.LED generally comprise housing, lampshade and The lamp composition being disposed therein, and the sealing of the combination of housing and lampshade is particularly important to use state and the life-span of LED.

The lampshade of traditional light fixture is fixing with housing generally uses two ways, but both modes are respectively present following Problem.

Encapsulating water-stop: because of the irreversibility after glue curing, the wire later stage cause because lampshade is bad need to scrap whole Lamp；, there are the problems such as glue cracking, variable color in UV resistant (weather resisteant) ability of glue after about 3 months after using, cause producing The decline of product lampshade sealing property loses sealing effectiveness.

The single anti-water surface water proof ring of lampshade seals: waterproof sealing area is little, and only one of which seals structure；Water proof ring produces dress Join difficulty, it is difficult to install and put in place, make yields of the manufacturing low, how much need to reprocess, test its waterproof sealing of guarantee Effect.

Utility model content

For solving the problem in above-mentioned conventional art, it is good that this utility model aims to provide a kind of sealed waterproof effect LED lamp waterproof sealing structure.

This utility model provide a kind of LED waterproof sealing structure, wherein, described LED include housing, lampshade and Water proof ring, described water proof ring is arranged between described housing and described lampshade, and described lampshade has first formed along its periphery Lobe, described water proof ring has the first concave part formed along its periphery, described first lobe and described first concave part Combining closely, the direction that described first lobe extends is formed certain between the direction that described housing and described lampshade are combined Angle, described angle is less than 10 degree more than 3 degree.

Preferably mode is, is formed with second in the direction contrary with described first concave part of described water proof ring protruding Portion, is formed with the second concave part, described second lobe and described second in described main body with the side faced by described housing The form fit of concave part, it is achieved described first lobe is combined closely with described first concave part.

The mode being more highly preferred to is, described housing, described water proof ring and described lampshade form nested structure after combining, and make LED and lampshade integral sealing effect reach IP68 grade.

According to structure of the present utility model, simplify the production assembling of housing, water proof ring and lampshade three, make production once Waterproof yields reaches 98%, reduces production cost；Can repeated disassembled and assembled lampshade and do not affect water resistance, can simple and fast dimension Repair lamp lampshade, reduce the scrappage in process of producing product.

In this utility model, housing, water proof ring and lampshade pass through interference fit, it is possible to make the connection of each parts more step up Close, improve classification of waterproof, and can arbitrarily dismantle, convenient maintenance, reduces and produces and maintenance cost, extend the use of LED lamp Life-span.

Detailed description of the invention

Below, in conjunction with accompanying drawing, this utility model is described in detail.It should be noted that these accompanying drawings are to make this The purpose of utility model, technical scheme and advantage are clearer and use, and following embodiment is only used for solving Release structure of the present utility model, and the restriction to protection domain of the present utility model can not be construed to.

The present invention provides the waterproof sealing structure of a kind of LED, and wherein, described LED includes housing, lampshade and waterproof Circle, described water proof ring is arranged between described housing and described lampshade, and it is protruding that described lampshade has first formed along its periphery Portion, described water proof ring has the first concave part formed along its periphery, and described first lobe is tight with described first concave part In conjunction with, the direction that described first lobe extends forms certain folder between the direction that described housing and described lampshade are combined Angle, described angle is less than 10 degree more than 3 degree.

It is formed with the second lobe, in described main body in the direction contrary with described first concave part of described water proof ring With the shape that the side faced by described housing is formed with the second concave part, described second lobe and described second concave part Join, it is achieved described first lobe is combined closely with described first concave part.

Described housing, described water proof ring and described lampshade form nested structure after combining, and make LED and lampshade integral sealing Effect reaches IP68 grade.

Wherein, IP68 is the highest level of classification of waterproof standard.How see water resistance, mainly see after IPXX two Numeral XX, first X is from 0 to 6, and highest ranking is 6；2nd X is from 0 to 8, and highest ranking is 8；The highest waterproof etc. Level is IP68.Also just saying, structure of the present utility model has the water resistance of highest standard.

Fig. 1 is the schematic perspective view that lampshade, water proof ring and housing are shown separately；Fig. 2 is that the rear solid of cutting open of Fig. 1 is illustrated Figure；Fig. 3 is the cross sectional portion schematic diagram of Fig. 2.

As Figure 1-3, LED includes lampshade 1, water proof ring 2 and housing 3.Water proof ring is arranged in the middle of lampshade and housing, Play the structure after lampshade and housing are combined and carry out sealing function.

In order to improve sealing effectiveness, the projection of lampshade and the groove of water proof ring are not vertically oriented (the lampshade and anti-of extension The direction that hydrosphere combines, or the direction that lampshade and housing combine, the above-below direction in Fig. 3), but i.e. scheme with vertical direction There is certain angle angle in the above-below direction in 3, the angle of this angle is more than 3 degree less than 10 degree.Described angle is preferred For the positive-angle gradually expanded from the top of Fig. 3 to bottom.

Water proof ring and lampshade and housing form interference fit, between there is no gap, there is good sealing effectiveness.

Lamp casing is designed by fold-type, increases the contact area with air, accelerates heat radiation.

Although above content describes detailed description of the invention of the present utility model, but those skilled in the art should manage Solving, this is merely illustrative, and on the premise of without departing substantially from principle of the present utility model and essence, can do these embodiments Go out multiple change and amendment.Therefore, protection domain of the present utility model is defined by the appended claims.
