A Research Study on Pigment Paste and Paint Contributing Energy Saving by Absorbing Energy from Light Sources and Emitting Light in the Dark

Glow in the dark (also called as photoluminescent) paints have the ability to absorb light from natural and artificial light sources and glow in dark medium. They can be easily charged since they have the ability to use ambient light (sun light, led lamps, fluorescent lamps etc.) as energy source. In case of emergency such as power outages occurred related to earthquakes and other natural disasters, the paint uses the energy absorbed and glows in the dark by emitting this energy in light form. Hence, it ensures safety by making emergency exits, stairs and information/safety signs visible for a while and prevent the accidents happen due to lack of lighting. Photoluminescent paints can also be applied onto light switches, baseboards, kitchen cupboard and decorative accessories. Besides, by the application of photoluminescent paint in tunnels and highways with intense vehicle traffic, the amount of energy used in both tunnel lighting and highways can be reduced by utilizing the light absorbed by the paint.Within the scope of this study, waterborne photoluminescent pigment paste formulation was created and the pastes were produced primarily. Afterward yellow-green colored pigment paste was selected (from a group of pigments that has different colors) to be used as colorant in waterborne road marking paint, bike lane paint, tennis court paint and hobby paint groups. The paint produced were applied onto test panels and luminance values and luminance time of the panels were measured.
