Phosphor beam gives Foton a bright future

摘要

The new PRG TruColor Foton is a small, lightweight and colour accurate variable-beam light that is claimed to be powerful, inexpensive and water resistant. It uses remote phosphor technology, which provides more accurate colour than LEDs. It is the first portable broadcast lamp to use remote phosphor, where an internal light source strikes a crystal impregnated with rare earth elements that then glows brightly. The large surface of the emitter allows for a precise mix of the phosphorescent material for accurate colours across the visible spectrum.
