Entertainment laser light shows are nothing new, but increasingly the laser projector technology developed for entertainment lighting is being adopted in architectural lighting. There are two fundamental ways of making white laser light sources. The first is combining at least three colored lasers, such as red, green, and blue. This is analogous to RGB LEDs creating white light. The second method is phosphor conversion of blue laser light where most of the light is phosphor converted to a combination of green, yellow, and red light, and enough of the original blue laser light is unconverted and mixed with the phosphor converted light to create white light. This is analogous to blue-pump, phosphor converted LEDs.
Lasers are being used more and more as city, landscape, or “beacon” lighting elements, to draw attention to a given landmark or facility. Lasers for architectural lighting can be used to project high-impact laser beams across the sky, with visibility for miles – easily drawing attention to a landmark or establishment. They can also be used for innovative applications like laser projection mapping that outlines a building or structure with laser light. Lasers for architectural lighting can also project classic effects, such as laser graphics, laser logos, laser text, and laser animations, across very long distances. See images below.
