Light Emitting Plasma (LEP)

Light Emitting Plasma, is an innovative solution designed to bring clean, natural lighting to a whole new level. This patented technology, developed by LUXIM, is a high intensity light source that offers bright, full-spectrum illumination in an energy saving and low maintenance package. LEP is used in large scale, high lumen applications, and is ideal for municipal, industrial, stadium, and street & area lighting.

Luxim manufactures a solid-state electrodeless lamp lighting system. Luxim technology is used in general lighting, entertainment lighting, instrumentation lighting and specialty lighting.

Their light-emitting plasma (LEP) lamp is claimed to be able to operate up to 50% more efficiently than conventional high-intensity discharge lamps (HIDs) while generating the same maintained lumen as a conventional 400-watt system at about half the energy.[citation needed] Luxim’s light-emitting plasma is designed to complement LED. LEP is designed for use in high illuminance applications.

When LED is not intense enough for your application consider LEP. Light Emitting Plasma consumes half the energy of Metal Halide or High Pressure Sodium and will still be at 80% lumen efficiency at 50,000 hours. These lights can be wirelessly networked for dimming, control and capturing data.SHOW LESS

Light Emitting Plasma (LEP), by Luxim, is poised to challenge the lighting technology and efficiency – not necessarily in the home arena, but in infrastructure, indoor/outdoor, and entertainment lighting.

The bulb contains gas and metal halide material.  When it is turned on, an electric field ionizes the gas molecules, creating a gas plasma.  The gas plasma in turn, vaporizes the metal halides.  The metal halides completely join the gas plasma, thus emitting a bright white light.

LEP bulbs are capable of intense light output. One manufacturer, Luxim, claims their technology can produce 144 lumens per watt. In contrast, Tungsten Halogen bulbs produce 15 lumens per watt, LED emitters produce between 65 to 85 lumens per watt (in practical applications), and HMI bulbs produce 90 Lumens per watt. While there is truth in this claim as it pertains to an LEP bulb in isolation, as with LEDs, manufacturers have not realized anything close to that kind of lumen efficiency within the framework of a practical light that will burn in all lamp orientations.

Benefits include:

  • Superior Light Distribution: Create optimal light distribution from a single, directional point source
  • Natural Illumination: Enhance visibility from a full spectrum plasma arc (up to 95 CRI)
  • Uncompromising Energy Savings: Reduce energy usage by 50% without sacrificing brightness levels
  • Worry Free Reliability: Eliminate failure modes and lumen degradation found in most lighting
  • Seamless Controls Integration: Connect to any lighting controls via built in control gear

When the pill sized LEP bulb in mounted in the “puck” so that it will burn in all head orientations, the emitting area is no more than 1/4″ x ¼.” In this configuration, the 273W LEP bulb will deliver 16000 lumens or 57 lumens per watt. While much less than the 37’000 lumens the bulb will generate fully exposed in a horizontal position, it cannot be tilted up in that orientation.

On the plus side, mounted so that it will burn in all orientations, all of its’ output is forward directed within a 60 degree angle so it doesn’t require a reflector. Such a highly localized forward directed light is ideal for Fresnel type instruments.

As close an approximation to the ideal point source that exists today, its light output favors the central portion of the Fresnel lens. Since, this part of the lens has greater transmittance, LEPs are a more efficient source for Fresnel type heads than tungsten filaments, LED arrays, and even HMI arcs. For this reason you get more of those lumens transmitted through the lens in a highly collimated light that is very clean and crisp making it great for cutting shadows or gobo effects. The 273W LEP bulb in a Fresnel type instrument has an output comparable to a 575W HMI Fresnel.
