Laser Light Manipulating Nanotechnology

The Parhelion LDG Light Bulb combines a nanotechnology based on Micro-Electro-Mechanical Systems (MEMS) with Parhelion’s own Zoisite laser module. The MEMS is miniaturized mechanical and electro-mechanical elements (i.e., devices and structures) that are made using the techniques of microfabrication. The size is at the one-micron lower end of the dimensional spectrum. The term used to define MEMS varies in different parts of the world. In the United States they are predominantly called MEMS, while in some other parts of the world they are called “Microsystems Technology” or “micromachined devices”. Parhelion is the first to use this nanotechnology with a laser. The technology not only the splits the laser source but manipulates the shaping of light through power control.


Fundamentally the LDG bulb is using a semiconductor fabrication for the laser diffraction and control of light intensity power. Combined with a specific light wavelength of the Zoisite laser and a unique MEMS chip to redirect, shape, and modulate a coherent light beam, the LDG is able to shine through fire, smoke, fog and other turbid environments including in water. The LDG bulb makes visible all objects in these challenging environments without the ‘blinding light cloud’ (e.g., blinding fog light) found with normal light sources.

21st Century Lighting: Destination Light Model 

Laser light has unique characteristics different than common source lighting used today. Have you ever noticed that a common nightlight will create shadows on the opposite side of the room? Or that you need several to light a long hallway? Common LED, florescent and incandescent bulbs pool the light around the source, creating shadows and dark corners and making it often necessary to use several units to light a large space.

Parhelion’s laser-based light solution called Destination lighting provided by the Firefly laser lamp and LDG light bulb enables surgical precision for directional lighting regardless of the volume of space to the destination. Laser activates photons in a way that not only illumines the destination point, it bypasses the smoke, or fog particles, diminishes shadows and avoids blinding light. Laser literally places the photons at the destination, with no shadow illumination for rooms, obstacles and dangers. Each of the laser light points emitted is in essence its own little point of light, its own light source. The diagrams below compare and illustrate the lighting concepts within a steel stairwell.
