Top 5 Reasons to use Plasma Lighting
- Superior Light Distribution: Create optimal light distribution from a single, directional point source
- Natural Illumination: Enchance visibility from a full spectrum plasma arc (up to 95 CRI)
- Uncompromised 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
The Plasma Lighting emitter is constructed of a small electrode-less quartz lamp encased by a ceramic resonator. This novel construction emits light, from a small area, in a forward direction into a lambertian pattern. The point source like characteristic provides many advantages in a luminaire’s optical performance. A smaller source reduces the amount of optics needed to achieve the required level of glare cutoff and illumination, while ensuring excellent uniformity, by design.
In addition, the directionality feature significantly improves luminaire efficiency. Since all of the light is already directed toward the area needing illumination, there are no optical losses from light going in the wrong direction. In most applications, LEP luminaires can achieve greater than 90% optical efficiency into the desired light distribution.
The plasma ‘arc’ directly emits a full-spectrum white light without the need for a secondary phosphor conversion like in LED or Induction sources. The natural illumination generated from the Plasma Lighting source greatly enhances visibility and color appearance with a CRI up to 95. The full-spectrum signature also provides increased mesopic/scoptopic illuminance (with S-P ratio of 2.4) which greatly enchances nighttime visibility at the time of day when street and outdoor lights are needed. Plasma Lighting’s natural illumination enables luminaires to create a safe and inviting environment.
Energy savings using Plasma Lighting luminaires comes from a combination of source and application efficiency. Plasma Lighting’s source efficacy, lumens created per watt consumed, is automatically 15-20% higher than an HID source since none of the power is wasted in heating electrodes. Plasma source efficacy ranges from 115- 150 LPW at operating temperatures. On the applications front, Plasma Lighting sources can be utilized more effectively than HID, induction or LED because of its directionality and size. The directional source prevents light from being trapped inside a luminaire. Point source optics effectively maps the source to the illuminated area preventing unwanted light spill (a source for glare and light-pollution).
The unique construction of the Plasma Lighting source and solid state driver eliminates all failure modes of traditional lighting. Plasma Lighting lamps do not display electrode failures or wall darkering that plague metal halide and HPS lamps. The solid state RF generator is a rugged, semiconductor device made to withstand extended, continuous use. A Plasma Lighting system for general lighting applications is rated for 70% lumen maintenance (L70) at 50,000 hours. It is important to note that unlike typical HID light sources, Plasma Lighting sources do not need to be de-rated for the length of operating cycles. In comparison, a typical 400W metal halide lamp can be expected to last 18,000 hours with a 50% survival rate. Its lifetime is de-rated by as much as 25% for lamp orientation and up to 50% for short operating cycles. Plasma Lighting does not have these limitations - greatly enhancing its reliability and resulting in lower maintenance costs.
The intelligent solid-state driver and an emitter configuration able to react quickly make Plasma Lighting the only high intensity source that can be dimmed down to 20% of light output, in just a matter of seconds, with both analog and digital controls. Not only that, but dimming actually increases the longevity of the Plasma Lighting source and the drive electronics. This capability creates an enormous opportunity for reducing energy consumption and operating costs when combined with the use of dimmers, and occupancy or daylight sensors.
