Description
More particularly, the present invention relates to a signboard for light, reflection, and more specifically, to allow light to be transmitted only through a rim portion of a black number and a red circle portion, And a light-emitting device.
In general, the road sign facilities include traffic safety signs that correspond to regulations, directions, cautions, and auxiliary signs, and road signs that show the status of roads. These signs are usually attached to a base plate of aluminum material with a reflex reflection paper And it is easy to identify characters or figures on a signboard at night through the recursive reflection of the light of a headlight of an automobile.
However, the conventional signs such as the above-mentioned conventional signs are relatively easy to identify the contents of the sign in the bright circumstance, but are limited to narrow angle of view due to the reflex reflection in the dark like night, Or roads for high-speed driving, the distance perceived by the driver is short, so that it is possible to identify only by approaching to a relatively short distance, and the risk of a traffic accident is extremely high.
Especially, in a region with a large diagonal difference, condensation occurs on the surface of the signboard due to the difference in temperature, so that the characteristic of the reflex reflection is completely lost, so that the information signetting function of the road sign can not be performed at all. And there is a serious demand for measures.
As an invention that partially alleviates these problems, an interior illuminated road sign has been proposed in which a fluorescent lamp is applied to the inside of a sign to enable active emission beyond the limit of passive recursive reflection.
An internal illumination type sign applied with a fluorescent lamp inside a signboard is configured to emit light from the signboard itself by incorporating an illuminating device in the inside of the sign to form a signboard or a color sheet on a flex material.
Such a method uses a 20W or 40W three-wavelength fluorescent lamp as the illumination device, so there is a disadvantage in that the power consumption is relatively high, additional maintenance such as frequent replacement of the fluorescent lamp and periodical cleaning of the label surface are added, There is a problem in that it can not be accurately identified at a long distance. Therefore, it has been used in some areas in the early days and has not been used until now.
Meanwhile, an external illumination system for illuminating the entire signboard by installing an external illumination from the outside has been developed. However, the range of improving the identification is limited to a narrow angle depending on the angle of the illuminated light. In contrast, There is a problem that the recognition of the content is increased while the recognition of the content is deteriorated due to the excessive reflection.
In addition, in addition to the signs of the above methods, a sign board in which an LED is attached in a protruding manner along the outline of a character or figure of a sign has been proposed. However, this technique has a problem that characters or a display figure is displayed on a cover surface by paint or the like, And a plurality of LEDs are provided along the shape of the display graphic to display the light.
Although the technology for installing LEDs has been disclosed in various structures, there is a disadvantage in that the illuminance is lowered due to the installation of caps or covers for protecting the LEDs. In order to overcome this problem, distant identification There was a drawback that it was almost impossible.
SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide an image display apparatus and a display method thereof, in which light is transmitted through only a rim portion of a black number and a red circular band, And a red circle, thereby enabling to distinguish clearly and accurately even at a long distance.
In addition, according to the present invention, by attaching a retroreflective sheet having a good transmittance to the front surface of the diffuser plate, the reflection function can be maintained even when the power applied to the first and second LED modules is shut off, , And to provide a reflective sign.
According to an aspect of the present invention, there is provided an image display apparatus including a diffusion plate for diffusing light, an outer plate projecting at a predetermined height along a circumference at a rear edge of the diffusion plate, An

According to the light-emitting and reflective signboard having the above configuration, light is transmitted only to the rim portion of the black number and the red circular band portion, and the remaining portion is not blocked or irradiated, thereby increasing the visibility of the black number and the red circle , So that the traffic sign can be accurately identified even at a long distance.
In addition, a retroreflective sheet having a good transmittance is attached to the entire surface of the diffuser plate, thereby allowing the LED light installed inside the traffic sign to be transmitted and maintaining the retroreflective performance, thereby significantly improving the visibility.
