Abstract

The utility model discloses a heat-dissipating light-shading device, and particularly relates to the heat-dissipating light-shading device which is used on light sources of transparent display equipment like glass to conduct heat dissipation to the transparent display equipment and prevent backlight of the transparent display equipment from projecting outwards. The heat-dissipating light-shading device comprises a base cover and a top cover, wherein an opening is formed in the middle of the base cover, an edge portion and a step-shaped upheaval portion are arranged on the top cover, a plurality of heat-dissipating holes are formed in the upheaval portion, and the top cover can be covered on the base cover. The heat-dissipating light-shading device can effectively dissipate heat generated by lighting devices like light-emitting diode (LED) lamps and avoids unnecessary projection of backside light sources of the LED lamps. In addition, the heat-dissipating light-shading device is simple in structure, convenient to install, low in cost and good in heat-dissipating/light-shading effect.

Description

A kind of heat radiation shade

Technical field

The utility model relates to a kind of heat radiation shade, relate in particular to a kind of presentation device of making for light transmissive materials such as glass light source, it is dispelled the heat and stops its unnecessarily outside heat radiation shade of projection backlight.

Background technology

Various presentation device is presentation device commonly used in the modern commerce activity such as showcase, show stand, showcase etc., in particular for showing the displaying of the articles of price such as bullion, antique, mobile phone, wrist-watch.In the above-mentioned presentation device, be typically equipped with the external light source illumination, such as shot-light, LED lamp etc., to obtain better bandwagon effect.One of normal light source mounting means that adopts is in end face or the bottom surface of presentation device double-layer clapboard to be set, lighting apparatus namely is installed in the space of double-layer clapboard formation, this mounting means easily produces the problem of following two aspects: 1, in the long-time process of using, the amount of heat that lighting apparatus produces is accumulated in the dividing plate space and can't distributes; 2, for the presentation device made from light transmissive material, the lighting sources such as LED backlight passes on the wallboard projection metope of presentation device, causes metope mottled and present the effect of " tracery wall ", the effect that impact is showed and indoor overall appearance.The common led light source of existing showcase normal operation, shade does not dispel the heat; And if use is equipped with the special light sources of heat radiation shade, will greatly raise the cost.

The utility model content

The utility model provides a kind of heat radiation shade for the above-mentioned technical problem that exists in the prior art, and it is simple in structure, easy for installation, cost is low, and heat radiation and/or good shading effect.

For this reason, the utility model adopts following technical scheme:

A kind of heat radiation shade is characterized in that: comprise end cover and overhead guard, the middle part of cover, the described end is provided with opening, and overhead guard has edge section and platform shape protrusion, has some louvres at described protrusion, and described overhead guard can be fastened on the end cover.

Further, the opening on the described end cover is lower large little truncated cone-shaped.

Further, upper bottom surface circumference along described opening is provided with the upper back-up ring of end cover, medial surface at described overhead guard protrusion is provided with back-up ring under the corresponding overhead guard, the upper back-up ring of described end cover can stretch in the space that overhead guard lower block circle forms and with overhead guard under back-up ring overlap in vertical direction.

Further, under the upper back-up ring of described end cover and the overhead guard back-up ring at intervals in the horizontal direction, the scope of this distance be end cover go up the back-up ring overall diameter 1/8 to 1/5 between.

Further, the bottom surface circumference along described opening also is provided with the lower back-up ring of end cover.

Further, the inner surface of the lower back-up ring of described end cover and end cover opening are on same round table surface.

Further, cover has some projections at the described end, and outside grab is formed on the top of this projection, is provided with corresponding bayonet socket at the protrusion of described overhead guard, and described grab can be fastened in the bayonet socket.

Further, described louvre is the ellipse that removes an end, distributes equidistantly along the whole circumference on platform shape protrusion top.

Further, cover of the described end adopts exotic material to make, and overhead guard adopts the material of high temperature resistant and shading to make.

Heat radiation shade of the present utility model, comprise the end cover and the overhead guard that cooperatively interact, during use, end cover can be fixed on the showcase wallboard that the lighting apparatus such as LED lamp are installed by modes such as screws, the back of LED lamp is contained in the opening at cover middle part, the end, again overhead guard is fastened on the overhead guard, installs and namely finish, very easy; Press grab, overhead guard can be taken off from end cover, make things convenient for simultaneously lighting apparatus is keeped in repair.Have some louvres at overhead guard, upper bottom surface circumference along described opening on end cover is provided with back-up ring on the end cover, medial surface at described overhead guard protrusion is provided with back-up ring under the corresponding overhead guard, the upper back-up ring of described end cover can stretch in the space that overhead guard lower block circle forms and with overhead guard under back-up ring overlap, like this, the back side light source of LED lamp is because the straightline propagation of light, be limited in the space of back-up ring and lower block circle formation, the heat that the LED lamp produces then can go by the outside that louvre is dispersed into showcase, has realized simultaneously the effect of shading and heat radiation; Bottom surface circumference along opening also is provided with the lower back-up ring of end cover; should cover lower back-up ring during use the end embeds in the showcase wallboard; the lower back-up ring thickness in vertical direction of end cover and the consistency of thickness of wallboard; so just form the resistant to elevated temperatures protective layer of a circle in the installation position of wallboard LED lamp, prevent wallboard in long-term use procedure by high-temperature damage.Simultaneously, because the utility model and lighting apparatus are device independently, lighting apparatus maintenance and replacing do not affect impracticable novel use, have reduced widely the cost of the shading of dispelling the heat.
