Description

Device for realizing red light guide character

Technical Field

The utility model relates to the technical field of light guide characters, in particular to a device for realizing a red light guide character.

Background

The light guide character is widely applied to various operating environments requiring night vision, such as an aircraft control panel, a ship control panel and the like. The white light guide characters are most common, and the characters can be in corresponding colors after the LED light emitting diodes (LED lamps for short) with various colors are arranged below the light guide plate and are lighted, so that the white characters are matched with the LED lamps with various colors to meet about 95% of application scenes.

However, some special keys (such as warning type or special careful operation is needed) on the control panel are provided with protective covers to prevent misoperation, and the character color of the corresponding keys is red (when the LED lamp is not lighted), so that the keys are distinguished from the common keys.

Because the red acrylic has poor light guide effect and is generally not used for character light guide, the red transparent acrylic is adopted to realize the double functions of character presentation and light guide in the traditional way. Unfortunately, the black visual contrast between the red transparent acrylic character and the key body is not very large under the condition of unlit, and the color is dark red, so that the warning or reminding effect is weakened.

The method is characterized in that the transparent acrylic character is directly matched with the red LED lamp to realize the red character presentation, and unfortunately, the character is not red under the condition of no lighting, and the character can only be presented red under the lighting condition. The warning and reminding means are omitted when the lamp is not lighted although the lamp is distinguished from other characters.

The other method is that the characters are directly sprayed with common red paint, but the common red paint cannot be used for realizing the function of conveniently night viewing when the characters emit light because the common red paint does not conduct light or conducts light very weakly.
