Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sign light for displaying characters, figures and the like.

[0002]

2. Description of the Related Art A conventional sign light is shown in FIG. In the figure, 20 is a lamp, and 21 is a transparent panel provided on the front of the lamp 20. The lamp irradiation side surface of the transparent panel 21
White (22) is applied to the entire surface, black (23) is applied to the surface except for the character portion to be displayed, and the color (eg, red) 24 of the character to be displayed is applied to the entire surface. In some cases, a milky white panel was used instead of the transparent panel 21.

When the lamp 20 is turned on, characters (for example, “in use”) are displayed on the anti-lamp irradiation side surface 21 ′ of the transparent panel 21 as shown in FIG. When the lamp 20 is turned off, the characters disappear and become invisible.

[0004]

According to the conventional sign light, light emitted from the lamp 20 is transmitted to the transparent panel 21.
(Or a milky white panel) enters the transparent panel 21 from the side end surface 21a, and light leakage occurs from the outer peripheral portion 25 (see FIG. 4) of the display surface 21 'of the transparent panel 21 by the same effect as the edge light. There was a problem of doing.

It is an object of the present invention to provide a sign lamp that does not cause light leakage on a panel display surface.

[0006]

The indicator lamp of the present invention comprises a translucent panel, a light source provided on the back of the translucent panel, a color layer formed on the entire surface of the translucent panel, It has a black layer formed on the surface of the color layer except for the marking pattern portion, and a white layer formed on the entire surface of the color layer in the black layer and the marking pattern portion.

[0007]

According to the structure of the present invention, since the black layer is formed on the surface of the translucent panel except for the sign pattern portion, even if the light of the light source enters from the side end face of the translucent panel. ,
Light is blocked by the black layer.

[0008]

1 and 2 show an embodiment of the present invention. In FIG. 1, reference numeral 11 denotes a translucent panel formed of a transparent panel, and a lamp (light source) is provided on the back of the translucent panel 11.
10 are installed. On the surface of the translucent panel 11,
A color layer (for example, red or the like) 12 corresponding to the color of a character (sign pattern) to be displayed is formed on the entire surface. Then, a black layer 13 is formed on the surface of the color layer 12 except for the mark pattern portion. Further, a transparent white layer 14 is formed on the entire surface of the black layer 13 and the color layer 12 in the mark pattern portion.
To form 12, 13, and 14 are red,
A black (sign pattern part is cut out) and white cutting sheet may be pasted.

When the lamp 10 is turned on, a sign pattern (for example, "in use") is displayed on the display surface 15 of the panel through the white layer 14, and when the lamp 10 is turned off, the sign pattern disappears. Disappears. According to the indicator light configured as described above, even if the light emitted from the lamp 10 enters the translucent panel 11 from the side end surface 11 a of the translucent panel 11, the black layer 13 on the display surface side causes the light. Light is blocked, and no light leakage occurs on the display surface 15 (FIG. 2).
reference).

[0010] Further, since the sign pattern is formed on the display surface 15 side of the translucent panel 11, the sign pattern is displayed more clearly than before when the lamp is turned on. The translucent panel 11 may be formed of a milky white panel. Further, the sign pattern is not limited to characters, but may be a figure, a symbol, or the like.

[0011]

According to the structure of the present invention, since the black layer is formed on the surface of the translucent panel except for the sign pattern portion, the light of the light source enters from the side end face of the translucent panel. Even so, an effect is obtained in which light is blocked by the black layer and light leakage does not occur on the display surface.
