Description

{Ligting structure of advertising signboard}

The present invention relates to an illumination structure of a signboard for advertisement, and more particularly, to an illumination structure of a signboard which illuminates the entire advertising surface of a large advertising signboard with a light source emitting a bright light with low power consumption will be.

Generally, fluorescent lamps have been widely used for brightly illuminating signboards for advertisements. Fluorescent lamps have been widely used these days because the light emitted from fluorescent lamps spreads 360 degrees in all directions, I think it is because there are advantages.

In the case of a signboard using a fluorescent lamp in the prior art, it is not a big problem when the signboard is simply used for brightly illuminating a business name or the like. However, when the signboard is used for advertising or promoting a product, The effect of the advertisement can be maximized only when the entire contents of the advertisement displayed on the signboard are illuminated with the same brightness rather than brightly illuminated.

However, it has been pointed out that the signboard using the fluorescent lamp as the light source has the same brightness as the advertising surface, or the signboard has a too large width, so that the weight is made heavy.

For example, in order to brightly illuminate the advertising surface of a signboard, a plurality of fluorescent lamps must be installed at regular intervals. When a plurality of fluorescent lamps are installed close to the advertisement surface, the fluorescent light illuminates the entire advertising surface with the same brightness And the advertisement surface of the portion located at a distance from the fluorescent lamp is brightly illuminated while the advertising surface of the portion far from the fluorescent lamp is illuminated in a relatively dark state. It is possible to illuminate the entire advertising surface with almost the same brightness, but in this case, since the plurality of fluorescent lamps are far away from the advertisement surface, the thickness of the signboard As the thickness increases, the reinforcement structure becomes necessary. As a result, A problem occurs.

In consideration of all the problems that appear in a signboard using a fluorescent lamp as a light source as described above, a signboard using an LED as a light source has been proposed in order to lighten a signboard and reduce power consumption.

LEDs have the advantage of emitting much brighter light while consuming much less power than fluorescent lamps. However, since LEDs can not illuminate all directions like fluorescent lights and emit light by emitting forward light, the entire advertising surface of the signboard is brightly illuminated It is necessary to install a large number of LEDs on the back side of the advertising surface in a longitudinally and laterally arrayed manner, so that not only the manufacturing cost of the billboard is increased but also the power consumption is increased due to the use of a large number of LEDs.

Conventional LEDs are fabricated to emit light with an angular width of 30 ° to 120 °. The narrower the angle of illumination of LED, the longer the distance of illumination and the larger the angle of illumination, Is shortened.

Therefore, in the case of a signboard using an LED module in which a plurality of LEDs are arranged at a predetermined interval on a printed circuit board having a narrow width and a long length, When the LED module is installed so as to emit light in a direction that makes it possible to illuminate the LED module in a direction in which the LED module is installed, On the other hand, there is a disadvantage in that the four-sided edge portion is illuminated relatively darker than the central portion, and in the case of the wide-width signboard having a width of the signboard of 2 m or more, the central portion of the signboard advertisement surface is not illuminated with the same brightness But the edge portion of the advertisement surface is illuminated in a dark state.

Accordingly, conventionally, when the LED is used as the light source, the power consumption can be reduced and the weight of the signboard can be reduced. However, not using the LED as the light source of the signboard means that the entire advertising surface of the signboard has the same brightness It is impossible to maximize the advertising effect because it can not illuminate the LED. Therefore, the LED is not applied as a light source to a large signboard, and thus it is limited to a small signboard.

In view of the above-described problems in the related art, the present invention has been proposed to illuminate the entire advertisement surface of the signboard with the same brightness even when LEDs are used as a light source for all large and small signboards. The lens housing is mounted on each of the plurality of LEDs arranged at regular intervals so that the light of each LED can be illuminated to a long distance while being illuminated within a narrow angular range of about 10 to 15 DEG, ~ 30mm, the reflector reflects the light emitted by each LED, and the interference effect of the light that emits in the same direction in each LED, the entire advertising surface of the signboard is made to have the same brightness In order to make it possible to brightly illuminate it.
