JPS5937820Y2 - Internally illuminated reflective sign display board - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a display board for an internally illuminated reflective sign that has improved visibility and legibility when the light is turned on and when the light is turned off.

In general, internally illuminated signs are the most visible signs at night, when visibility and legibility are especially required, but when the lights are dimmed, visibility and legibility are extremely reduced, so they have traditionally been the most visible signs. As shown in the figure, patterns, characters, etc. 2 are printed on the rear surface of the transparent plate 1 which is the outside side of the display board, and a translucent layer is formed between it and the opalescent white board 3 which is the inside side of the display board. A display board has been proposed in which the reflective tape 4 is interposed to provide the retroreflective effect of the headlights of automobiles and the like, thereby improving visibility and legibility.

However, the retroreflective performance of the retroreflective layer interposed in the display board is significantly affected by the shading of the printed surface of the transparent board, and the display board is manufactured within the specified chromaticity range required for light signs. If an attempt is made to produce a display panel that satisfies the retroreflection effect, the chromaticity cannot be within a predetermined range.

The present invention solves the above-mentioned drawbacks, and includes a translucent reflective sheet interposed between the opalescent plates of a transparent plate with the same display contents printed on one side, and a transparent reflective sheet. The printed side of the board and the printed side of the opalescent board are faced so that the respective designs, letters, etc. overlap, and the transparent board
By placing the milky white plate and the translucent reflective sheet in close contact, the retroreflective performance of the translucent reflective sheet will not be degraded when the lights are turned off, and the chromaticity range required for ignition signs will be ensured when the lights are turned on. visibility of displayed content;
The purpose of the present invention is to provide a display board for an internal light reflective sign with excellent legibility.

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 2, reference numeral 11 denotes a transparent plate on the outside of the display board, on the back of which a pattern, characters, etc. 12 having desired display contents are printed.

Reference numeral 13 denotes a milky-white board which becomes the inside side of the display board, and on its front or back side, there are designs, characters, etc. 1 printed on the back side of the transparent board 11.
Print the same design, support legs, etc. 14 as in 2.

Reference numeral 15 denotes a light-transmitting reflective tape serving as a retroreflective layer interposed between the transparent plate 11 and the opalescent plate 13, and can be adhered to the transparent plate 11 side or the opalescent plate 13 side as appropriate.

In the present invention, a pattern printed on the rear surface of the transparent plate 11,
The printed surface of the letters etc. 12 is made thin to the extent that the retroreflection performance of the translucent reflective tape 15 is not deteriorated, and
The printed surfaces of the designs, characters, etc. 12 on the transparent plate 11 side and the designs, characters, etc. 14 of the milky white board 13 are made to face each other so that they overlap each other.

Transparent plate 11 arranged and configured as described above. The opalescent plate 13 and the translucent reflective tape 15 are brought into close contact with each other to form the sign casing (
Not shown.

) in the front opening.

This invention utilizes the designs and letters on the transparent plate when the lights are off during the day or at night, and improves visibility and legibility through the retroreflective effect of the translucent reflective sheet. , when lit, the designs on both the transparent plate side and the milky white plate side,
By using characters, etc., and overlapping these designs, characters, etc., it is possible to ensure a predetermined chromaticity and improve visibility and legibility.

In addition, by printing designs, characters, etc. on the opalescent board on the back side, the printing process can be shared with that of transparent boards, and it can be manufactured using the same process as conventional display boards, which has great practical effects.
