Abstract

The utility model discloses a water-proof structure of a lamp. A water-proof groove is formed in a lamp shell; at least one convex ridge is arranged on the bottom surface of the water-proof groove, so that after a sealing strip is loaded, the convex ridge can be embedded in the sealing strip, the part, protruded out of the bottom surface of the water-proof groove, of the convex ridge can be tightly wrapped by the sealing strip, and tight sealing contact is formed; due to the fact that the convex ridge protrudes out of the bottom surface of the water-proof groove, a water-baffle step can be formed, a small part of water can be prevented from penetrating from a clearance between a glass light-permeating plate and the lamp shell; due to the fact that the structure is adopted, the requirement on the flatness of the bottom surface of the water-proof groove and the sealing surface of the sealing strip can be reduced, thus the technical difficulty is greatly reduced, and the cost is also reduced.

Description

A kind of light fixture waterproof construction

Technical field

The utility model relates to a kind of light fixture, particularly a kind of light fixture waterproof construction.

Background technology

LED wall lamp is for building light fixture attractive in appearance, beautifies for illumination and the light efficiency of metope.Because this light fixture is through being usually used in open air, the hot-air running into sometimes out of doors in the very large weather of the temperature difference (as in the unexpected rainfall of hot weather) lamp body is met cold contraction, the inner negative pressure that forms of lamp body, thereby be easy to the rainwater being detained on the glass passing through plate outside lamp body to suck between lamp casing and sealing strip, thereby may cause lamp interior circuit to make moist, or even short circuit, have a strong impact on the service life of light fixture, and the waterproof construction of common LED wall lamp is to carry out waterproof by sealing strip is set between the capillary groove at lamp casing and glass passing through plate, and the lamp casing of LED wall lamp is longer, thereby it is also a strip region with the sealing surface that contacts of sealing strip, in order there to be good waterproof effect, the area planar degree that capillary groove bottom surface contacts with sealing strip requires high, and the flatness of the face that sealing strip is contacted with capillary groove bottom surface requires also high, if out-of-flatness, must put on sealing strip and make sealing strip generation moderate finite deformation just can make up the difference of height that out-of-flatness brings by glass passing through plate with very large pressure.But the deformation of sealing strip is limited, and the excessive glass passing through plate that also may damage by pressure of pressure, thereby the flatness that people can only improve sealing strip and capillary groove bottom surface as far as possible ensures good sealing, but above-mentioned measure difficulty of processing is large, cost is high.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of light fixture waterproof construction.

The utility model solves the technical scheme that its technical problem adopts:

A kind of light fixture waterproof construction, is characterized in that: comprise lamp casing, be provided with capillary groove in lamp casing, capillary groove bottom surface is provided with at least one fin.

The profile of the outstanding capillary groove bottom surface portions of described fin is smoothly connected and is formed by lines.

The outline line of the outstanding capillary groove bottom surface portions cross section of described fin forms by two skew lines that are oppositely arranged and with the circular arc that two skew lines are smoothly connected.

The beneficial effects of the utility model are: in lamp casing of the present utility model, be provided with capillary groove, capillary groove bottom surface is provided with at least one fin, thereby when pack into after sealing strip fin can embedding sealing bar in, it protrudes from capillary groove bottom surface portions can be tightly coated for sealing strip institute, form sealing contact closely, and fin protrudes from capillary groove bottom surface and can form a dash ladder, also can block the water that small part is infiltrated from the gap between glass passing through plate and lamp casing, and there is said structure, the requirement of the flatness of the sealing surface to capillary groove bottom surface and sealing strip can reduce, thereby greatly reduce technology difficulty, thereby also reduce cost.

Brief description of the drawings

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is application schematic diagram of the present utility model;

Fig. 2 is the end view of lamp casing;

Fig. 3 is that sealing strip is installed on the view in lamp casing.

Fig. 4 is the cross-sectional profiles figure of fin.

Detailed description of the invention

Referring to figs. 1 through Fig. 4, the utility model discloses a kind of light fixture waterproof construction, comprise lamp casing 1, in lamp casing 1, be provided with capillary groove 2, capillary groove 2 bottom surfaces are provided with a fin 3, thereby when pack into after sealing strip fin 3 can embedding sealing bar 4 in, it protrudes from capillary groove 2 bottom surface portions can be tightly coated for 4 of sealing strips, form sealing contact closely, and fin 3 protrudes from capillary groove 2 bottom surfaces and can form a dash ladder, also can block the small part water infiltrating from the gap between glass passing through plate 5 and lamp casing 1, the profile of fin 3 outstanding capillary groove 2 bottom surface portions is smoothly connected and is formed by lines, said structure ensures that the profile of fin 3 outstanding capillary groove 2 bottom surface portions can not form cusp, thereby on whole piece fin 3, can not there is sharp edge, avoid sharp edge can hurt sealing strip 4 when with sealing strip 4 close contact and reduced waterproof effect and had water can infiltrate lamp body.

As shown in Figure 4, in this instantiation, the cross-sectional profiles line of fin 3 outstanding capillary groove 2 bottom surface portions forms by two skew lines that are oppositely arranged 6 and with the circular arc 7 that two skew lines 6 are smoothly connected, said structure has ensured can closely and smoothly fit with the face that is embedded into of sealing strip 4 after fin 3 embedding sealing bars 4, plays better waterproof effect.

Certainly, above-mentioned is only the application's a kind of concrete structure, do not form the restriction to the application, fin 3 also can be two or three etc., and the profile of fin 3 outstanding capillary groove 2 bottom surface portions also can be semi arch, or two the straight line being oppositely arranged and the circular arc that is smoothly connected with two straight lines form, also can be other curved lines and form.

A kind of light fixture waterproof construction above the utility model embodiment being provided, be described in detail, applied specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment is just for helping to understand method of the present utility model and core concept thereof; , for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model meanwhile.
