Problems solved by technology

[0002] Among the existing advertising LED acrylic panel luminous lettering process, the yellow and white board acrylic panel luminous lettering process is rarely used because of the technical problem of turning yellow into white. The non-modified yellow-white board made of acrylic material is made of a built-in LED light source with a specific color temperature. When the built-in light source is turned off, the font surface is yellow. After the built-in light source is turned on, the font surface is off-white. The problem of light transmittance and light source synthesis and color change, the brightness of the luminous characters is not high enough, the efficiency of light transmission from yellow to white after the built-in light source is turned on is very low, the positive white light cannot be converted well, the yellow interference cannot be completely removed, and the visual effect is not ideal. question

Abstract

The invention discloses a preparation method of LED yellow and white acrylic panel luminous characters. By optimizing and improving the yellow and white acrylic panel and a built-in special LED light source with a color temperature of 100000K+, the problem of turning the emitted light into normal white can be effectively solved, so that the luminous characters of the LED yellow and white board can be turned on. After the built-in light source, the special yellow-to-white conversion efficiency is high, the white is pure, and it is not disturbed by bright external light. It can be applied to any use scene and is not affected by the font size and thickness.

Description

technical field [0001] The invention relates to the technical field of advertising luminous characters, in particular to a preparation method of LED yellow and white acrylic panel luminous characters. Background technique [0002] In the existing advertising LED acrylic panel luminous word process, the yellow and white board acrylic panel luminous word process is rarely used because of the process problem of turning yellow to white. The rarely seen yellow and white board acrylic panel luminous words, the panels are all made of The non-modified yellow and white board made of acrylic material is made with the built-in LED light source with a specific color temperature. When the built-in light source is turned off, the font surface is yellow. When the built-in light source is turned on, the font surface is almost white. The problem of light transmittance and light source synthesis and color conversion, the brightness of the luminous characters is not high enough, the efficiency...
