LDG Light Bulb


Nanotechnology Laser Light

The LDG (Laser Diffraction Grating) Light Bulb combines the Parhelion Zoisite laser with a light manipulating nanotechnology (MEMS) to provide unique benefits that can be applied to use in many products. The LDG is able to shine through fire, smoke, fog and other turbid environments including in water. The LDG makes visible all objects in these challenging environments without the ‘blinding light cloud’ (e.g., blinding fog light) found with normal light sources. Further the MEMS can be optimized for different applications of lighting such as vapor detection or difficult lighting surfaces. The Zoisite laser module taken alone can be utilized in applications such as assay reactions, or requirements for continuous laser performance, etc. The Zoisite laser and results of microfabrication for light manipulation represent the foundation upon which Parhelion is advancing its laser-based solutions in new and existing markets. Here are examples of where we are going with the LDG and its Zoisite laser module.

Emergency Escape Lighting

LDG-BatteryUnit-New

Parhelion EL concepts

The LDG light bulb is designed as a continuous laser lamp providing smoke penetrating light eliminating the blinding fog effect. The LDG laser source is energy efficient to permit up to 5-times longer operation for existing battery emergency light units. Simply remove the light bulb on today’s existing emergency and replace with the LDG bulb.

 

Exit Lighting

The powerful uniqueness of LDG is to shine hundreds of feet with little loss of brightness and reduction of shadows. It illuminates difficult areas such as stairwells, hallways, warehouses and crowded space using less than 1 watt of power.

 

Industry Piping

LDG-Pipes

The Destination illumination model limits the creation of shadows and is suited for complex industry piping infrastructures. Typical LED or other traditional sources produce shadows around piping creating areas void of light. The LDG bulb produces lighting without shadows and behind piping. This type of lighting pipe crawl areas can be achieved to discourage potential terrorist espionage.

 

Subsea Monitoring

LDG-SubseaPipeLaser-based lighting provides a unique property to cut through mist and water without creating a blinding fog. It is especially effective in murky water conditions as these are similar to smoke and platform lighting in difficult weather conditions. The LDG complete enclosure and passive cooling has shown potential to provide lighting in turbid subsea monitoring as an alternative to current solutions using of LED strobe lighting.

 

Advanced Smoke Alarms

LDG-SmokeAlarm

Parhelion concept

Due to its low energy consumption, the LDG can be fitted to an existing smoke alarms without interruption of operation to provide an emergency light to navigate a smoke filled room or hallway. What would be more practical than having a smoke penetrating light on a smoke alarm for escape. Further, the resulting laser light can provide a more visual signal for the hearing impaired or at a distance when an alarm cannot be heard.

 

Guide Escape Smoke Alarms

LDG-EscapePathThe LDG lighting can be integrated with wireless communication between smoke alarms to calculate escape path lighting the way through smoke using the LDG light.

 

 

Advanced Night Light

LDG-WirelessEscapePathWall socket version of the LDG light with wireless capability can be produced like a common nightlight. This would contain a battery power source possibly being charged by the wall socket. The smoke alarms can then be integrated to signal the LDG nightlight to turn on or a power outage to light the way.

 

Vapor Monitoring

The LDG beams of coherent light create a point of reference for normal atmospheric conditions and potentially provide indication of any vapor disturbances (e.g., invisible leaks appear to flicker the light and provide a nebular dance). The LDG bulb matrix diffraction grating of laser beams create a static net that is visible when disturbed by vapor disturbances such as invisible gas leaks; specifically when dark.

 

Intrinsically Safe Lighting

LDG-IntrinsicLightingA laser-based light does not “pool” around the light source like LED or other traditional sources; the laser light is “thrown” long distances and maintains its brightness. Meaning the lighting device can be in one location while lighting a location a distance away. The LDG technology can provide an intrinsically safe lighting solution. Intrinsically safe lighting equipment and wiring is equipment and wiring which is incapable of releasing sufficient electrical or thermal energy under normal or abnormal conditions to cause ignition of a specific hazardous atmospheric mixture in its most ignited concentration. The LDG bulb can be brought into any hazardous location of any Group classification for which it is accepted without requiring explosion-proof housing or other means of protection.

 

Portable Medical Test Design Primers

The Parhelion Zoisite laser design with its self-contained passive cooling and mass production-profile makes it practical for use in portable medical lamp kits for a set of newly designed primers. A laser of specific frequency can be used for inventions relating to molecular biology and diagnostics, more in particular detection of (infectious) diseases. Parhelion is currently involved in the use of its laser component design for the field of lamp kits for detection of parasites comprising specifically designed primers.

 

Aircraft Emergency Lighting

The combined low energy consumption, and laser diffraction grating technique permits the LDG to be used on aircraft for congested areas for emergency escape lighting in fire and smoke. Parhelion sees this as a potential market for its LDG bulb with little affects on existing aircraft interior design. The LDG bulb can reach deep down a passageway without loss of intensity with smoke penetrating light.

 

Automobile Interior Light

LDG-AutoInternalLight

Simulated image produced

The LDG is a viable energy efficient solution for lighting an automobile trunk. It is has low power consumption, as most likely the automobile is not running and power is direct from battery. Most unique is the splitting of beams to not ONLY outline corners but can reduce effect of objects (i.e. luggage) blocking light and achieve better lighting than existing lights.

 

Automobile Fog Light

LDG-RNDThe unique LDG technology for splitting a laser beam and specific light wavelength can be used for an astonishing automobile fog light. The LDG Bulb uses a MEMS component appropriate for roadway Fog penetrating light. The laser light penetrates fog for navigation, not to be confused with lighting. The result provides a night vision effect; a clear advantage in a dangerous environment. Objects are outlined. Any hit objects with a laser beam become clearly visible.
