Easily ventilating and radiating dustproof light box structure

Abstract

The invention belongs to the technical field of advertisement light boxes and discloses an easily ventilating and radiating dustproof light box structure. The structure comprises a light box outline border, wherein two sides of the light box outline border are respectively provided with a ventilation opening and a ventilation slot pipe having a vent is arranged between the ventilation openings on two sides of the outline border. The light box can efficiently decrease the negative influence on the pictures in the light box of the stronger external wind power and can ensure the straight and clear picture display effect of the light box. Besides, the box has excellent ventilating effect, can radiate the interior heat in time, has excellent dustproof effect so as to remove dust automatically, and the box is convenient and reliable to use.

Description

technical field [0001] The invention belongs to the technical field of light boxes, and in particular relates to a light box body structure for ventilation, heat dissipation and dust removal. Background technique [0002] In the prior art, the advertising light box needs to dissipate heat due to the luminous light tube inside the light box, which is more obvious for some underground tunnels or subway interiors. Usually, for the purpose of heat dissipation, there are air inlets on both sides of the box of the light box for ventilation and heat dissipation, but in the track area of ​​the subway, when the train arrives, the running of the train brings a relatively large wind force, which should be relatively large. The strong wind enters the inside of the light box from the diameter of the air inlet, forming a large negative pressure area in the box. The negative pressure will make the pictures in the box shake and deform, which will not be straight, seriously affecting the dis...

Problems solved by technology

Usually, for the purpose of heat dissipation, there are air inlets on both sides of the box of the light box for ventilation and heat dissipation, but in the track area of ​​the subway, when the train arrives, the running of the train brings a relatively large wind force, which should be relatively large. The strong wind enters the inside of the light box from the diameter of the air inlet, forming a large negative pressure area in the box. The negative pressure will make the pictures in the box shake and deform, which will not be straight, seriously affecting the display effect of the picture, and the advertising effect of the light box is poor. ; Moreover, the larger wind force will directly blow the dust in the air to the inside of the box, and the dust blown into the box will be attached to the reflector, soft plate, light-emitting light tube or picture itself, seriously affecting the clear advertisement of the light box effect; in addition, when a lot of dust gathers inside the box, it is necessary to regularly open the box of the light box for dust removal and cleaning, which is extremely inconvenient to operate. At the same time, some dust hidden in the box is also difficult to remove, and the dust removal effect is poor , it is difficult to guarantee the clear advertising effect of the light box
