Light distribution method for advertising lamp box and advertising lamp box

Abstract

The invention discloses a light distribution method for an advertising lamp box and the advertising lamp box. The light distribution method comprises an edge lighting step and a middle lighting step,wherein the edge lighting step comprises a sub-step of arranging an LED light bar capable of realizing single-side lighting in the advertising lamp box along the inner wall of the lamp box so as to perform lighting from the inner wall of the frame to the middle; the middle lighting step comprises a sub-step of arranging a plurality of LED light bars capable of realizing double-side lighting in themiddle of the interior of the advertising lamp box so as to perform lighting on double sides; and the central plane of lighting surfaces of the single-side lighting LED light bar and the double-sidelighting LED light bar is configured to be parallel to the advertising surface of the advertising lamp box. The light distribution method disclosed by the invention is particularly applicable to illumination of the advertising lamp box, and under the condition that the effect of the advertising lamp box is the same as that of the traditional lighting tool, the advertising lamp box has the advantages of being environmental-friendly, capable of firmly fixing the lens without easy falling, high in structural strength, applicable to a large lamp box, low in manual installation cost and the like.

Description

technical field [0001] The invention belongs to the technical field of advertising equipment, and in particular relates to a light distribution method of an advertising light box and the advertising light box. Background technique [0002] Lighting is an indispensable requirement in human social production and industrial production. Since Edison invented the incandescent lamp, it has been popularized on a large scale. So far, the mainstream electric lighting technologies include the following: incandescent lighting, fluorescent lighting and LED lighting. . At present, incandescent lamps have been basically eliminated, and are only retained in some special fields; fluorescent lighting is the current mainstream, although it is gradually being replaced by LEDs, it still occupies the mainstream position in terms of the current market. The main reason is that its production process is very mature, and the equipment procurement cost is extremely low; LED lighting is gradually exp...

AI Technical Summary

Problems solved by technology

[0003] However, in some special fields, LED still does not have obvious advantages over traditional fluorescent lighting; It is still fluorescent lighting; although, there are also a small number of LED lamp replacement solutions, but it also has obvious disadvantages

For example: the light angle of a single LED light bar is small, and the lighting effect is not as good as that of fluorescent lamps. This is because fluorescent lamps emit light at 360°, so they have excellent applications in light box lighting, while traditional LED lights cannot be made due to heat High-power lighting, and its luminous angle is not as good as fluorescent lamps; thus, when using existing LED lamps to replace fluorescent lamps for light box lighting, it needs to be replaced at a ratio of at least 2:1, that is, one fluorescent tube needs to use two or Replacement of more LED light strips can avoid the occurrence of bright and dark zebra crossing lighting defects that affect the overall lighting effect of the light box

[0004] On the other hand, the existing LED lamps used for light box lighting often add small lenses to scatter the light source emitted by the LED lamp beads to improve its lighting effect, which improves the above-mentioned defects to a certain extent, but does not fundamentally solve the problem

And this also brings additional problems: since the lens is bonded to the PCB board by glue, a part of the lens will fall off during transportation or installation, which not only affects the appearance, but also affects the lighting effect; The problem has not been completely resolved, affecting the reliability and market share of LED products in advertising lighting

[0005] In the third aspect, the labor cost of installation also needs to be considered. After replacing LED lights, the number of corresponding lamp tubes will increase exponentially, which will significantly increase the cost of manual installation and maintenance in the later stage; In developed countries where labor costs are already high, it will lead to a significant increase in the overall comprehensive cost of the product

[0006] Therefore, as far as the LED lighting solution in the prior art is concerned, it cannot be well qualified for the special field of light box lighting.
