Currently, many colored luminous powders are produced by adding a certain amount of coloring powder to conventional luminous powder. The coloring powder affects the brightness of the luminous powder to some extent. A customer recently inquired about methods to enhance the brightness of luminous powder without changing its red color.

First, let’s explain the factors influencing luminous powder brightness. For luminous powder to emit light properly, it must first absorb a sufficient amount of light energy. Sunlight, artificial lighting, natural light, and ultraviolet rays can all stimulate the light source of luminous powder. No obstacles should interfere with the light absorption process, as they reduce light intensity and prolong absorption time. Similarly, no obstructions should occur during the emission process, as they diminish the inherent brightness.

Therefore, to increase the luminance of luminous products without altering their color, the only solution is to provide sufficient light exposure time for the product to reach saturation in light absorption. Ultraviolet radiation rapidly saturates the light absorption of luminous products.

When mixing luminous powder into paint, be sure to use a colorless varnish with high light transmittance. This not only improves light absorption but also prevents luminance degradation. Finally, it’s crucial to select the maximum additive ratio within the recommended range. For example, if the luminous powder ratio is 10%–30%, choosing 30% will enhance the brightness of the luminous product.
