Description

  The present invention relates to a display means such as a road sign having an internal illumination means, and in particular, a fiber sheet is used for the display surface base material and the back plate of the illumination device, so that the images of day and night are equivalent and the backlight is backlit. It provides an internally illuminated sign that can be countered.

2. Description of the Related Art Conventionally, in road signs and the like, road signs in which a transparent reinforced plastic plate is provided on the surface of a frame having illumination means inside, and reflective materials such as letters, arrows, and symbols are provided on the marking surface are known.
According to such an internal illumination sign, the display on the sign surface can be clearly recognized even at night.

Such a road sign is disclosed in, for example, Japanese Patent No. 3468506. In the present invention, a transparent reinforced plastic plate is provided on the surface side of the frame body, and the display portion is configured on the surface using a reflective material such as a base material and a reflective material such as letters.
In addition, a translucent milky white reinforced plastic plate is provided on the back of the frame, and when sunlight is received from the back side of the road sign, a part of the sunlight passes through the display part through the translucent plastic plate. The label portion can be seen well even in backlight.

  In addition, for example, a glass fiber sheet for light diffusion is used in the lighting device, and a technique for appropriately diffusing light from a light source (see Japanese Patent Application Laid-Open No. 2001-55646), or a display base material of a fiber sheet made of, for example, a polyester fiber layer And a light scattering particle-mixed plate that partially transmits reverse light, and a display body made of a reflective material such as arbitrary characters and symbols on such a display surface base material is known (see Japanese Patent Application Laid-Open No. 2002-317411). It has been.

However, these conventionally known sign means have illumination means inside, especially like large road signs, in addition to the visibility of signs by natural light during the daytime and the visibility of signs by the internal illumination means at night. It was difficult to simultaneously improve the visibility of the sign when backlit.
In addition, it has been difficult to reduce the weight of the device in a large road sign or the like and relatively increase the strength.
