Technologywith LEP

Superior Light DistributionThe LEP 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 luminaires 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.

Full Spectrum, Natural Illumination

Natural IlluminationLEPs 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 LEP 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. LEPs natural illumination enables luminaires

to create a safe and inviting environment.

EFFICIENCYLEP Luminaires can achieve greater than 90% optical efficiency in most applications

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.

Application Efficiency: LEPs directional point source allows luminaire designs to maximize the amount of useful light for a target illumination area eliminating wasted light in the form of glare and light pollution.

Natural Illumination: LEPs full spectrum mimics natural daylight delivering accurate color rendering and improved visibility.

Uncompromised Energy Savings

Energy savings using LEP luminaires comes from a

combination of source and application efficiency.

LEPs 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, LEP 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).

Worry-Free ReliabilityThe unique construction of the LEP source and solid

state driver eliminates all failure modes of traditional

lighting. LEP 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.

An LEP 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, LEP 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.

LEP does not have these limitations - greatly enhancing

its reliability and resulting in lower maintenance costs.

Seamless Controls IntegrationThe intelligent solid-state driver and an emitter configuration able to react

quickly make LEP 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

LEP 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.

The LEP driver has many built in functionalities including:

> Direct 1-10V input for dimming > Direct low voltage input control by occupancy sensors > Serial interface for digital controls (can interface to DALI and other controls protocols)

> Logging of operating parameters including temperature, voltage, current and other diagnostics

5Unlike traditional HID, dimming with LEP actually increases the longevity

of the source and the drive electronics.

LEP System Overview; Built-in control gear compatible with analog and digital lighting controls

The Science Behind LEPLUXIMs novel plasma lighting architecture consists of two primary parts:

> Emitter: A lamp embedded in a ceramic resonator > Radio Frequency (RF) Driver: Both a solid-state amplifier andmicro-controller

A radio-frequency signal is generated by the solid-state RF driver and is then guided into the ceramic

resonator through a low loss coaxial cable. The structure of the resonator concentrates the RFfield

delivering energy to the fully-sealed lamp without electrodes and filaments. The highly concentrated

electric field ionizes the gasses and vaporizes the halides in the lamp - creating a plasma state at its

center - resulting in an intense source of white light. Inside the back of the lamp, a diffuse yet highly

reflective material is used to reflect all of this light in a forward direction. The color of the light is tailored by

the fill chemistry inside the lamp to provide a naturally white and high color rendering light.

Step 1

An RF circuit is established by connecting an RF power amplifier to a ceramic resonator known as the puck. In the

center of the puck is a sealed quartz lamp that contains materials consistent with metal halide lamps.

Step 2

The puck, driven by the power amplifier, creates a standing wave confined within its walls. The electric field is strongest at the

center of the lamp which first ionizes the gasses creating a glow.

Step 3

The ionized gas in turn heats up and evaporates the metal halide materials forming an intense plasma column within

the lamp. This plasma column is centered within the quartz envelope and radiates light very efficiently.

By DesignA single LEP lamp, the size of a tic-tac, can replace a large HID lamp or 200 high power LEDs.

The brilliance of the LEP architecture lies in its simplicity. The principal idea is to energize a plasma arc,

without filaments or electrodes, and thereby eliminate all failure modes and inefficiencies of an HID lamp.

Superior Source Efficacy

Use LEP for High Lumen Applications (10,000+ Lumens); Use LED or HID for Mid and Low Lumen Applications.

The LEP SolutionLUXIM offers a full line of clean lighting solutions for high lumen applications ideal for replacing 250W and above HID lamps

and ballasts. With roughly half the power and a 50,000 hour rated life, LEP can help end users achieve a payback of lessthan

2 years in most lighting installations. LUXIMs products include an LEP emitter, RF driver, and co-axial connection available in

different lengths (an additional AC-DC converter is needed for use in a luminaire). LUXIMs products are tested and certified to

both North American and International Standards.

LEP vs. LEDWhile LEP is a category of solid state lighting, it is not an LED. The

main difference being the use of the solid state device; LEP uses the

device to generate RF energy which powers the plasma light source

LED uses the device itself for light generation. Some of the similarities

include the directionality of the light output, component reliability, and

control systems integration. The main difference between the two Is

performance - LEP provides higher lumen density (200X greater), and a

full color spectrum without phosphor conversion resulting in superior

performance in higher lumen applications.

LEP vs. HIDLEPs innovation over HID light sources is the removal of

electrodes and use of solid state electronics, which results in

better source efficacy, application efficiency, and reliability.

Powering a lamp without electrodes in a compact resonator

allows a completely sealed and more robust quartz lamp,

a directional beam pattern to improve optical efficiency, and

the ability to dim without impacting lamp life. Similar to HID,

LEP sources have the ability to scale to high lumen packages

easily without the need of multiple sources.

Case StudyLocation: Saint Francis High School, Mountain View, CA

Application: Indoor Gymnasium (retrofit)

Saint Francis High School required better lighting for their gymnasium, but also

wanted to reduce their environmental footprint. The existing 400W metal halide

lighting gave the facility a poorly illuminated appearance and was costly to operate

and maintain. The schools Facilities Director wanted the gym (which operated 15

hours/day) to be an attractive venue for its teams and decided an LEP solution

would address all of the schools needs.

Solution: H400 highbay luminaire (using STA-41-02 LEP system, 280W) to replace 470W Metal-Halide highbay.

Results> Reduced annual energy and maintenance costs by 45% (savings of $177 per fixture annually, 3.4 year simple payback on retrofit)

> Improved footcandle (lux) levels compared to previous 400W metal halide lamps

> Improved CRI from 65 to 95 providing improved visual acuity and appearance

> Ease of retrofit; able to swap out each luminaire in 15 minutes

> Eliminated ballast noise

> Reduced environmental footprint; installing LEP luminaires amounts to removing 26 tons of CO2 from the atmosphere (same amount sequestered by 5 acres of pine forest)

Case StudyLocation: Scottsburg Indiana (US I-31 and IN-56)

Application: Street and Roadway

When the City of Scottsburg decided to upgrade its lighting from High Pressure Sodium,

they found that LED solutions were too costly for their budget and would not provide the

amount of light needed to light their streets. They became interested in an LEP solution when

they found out it would allow them to reduce the number of luminaires by 30% to 50% - while

still maintaining existing light levels. Straylight Technologies, an LEP lighting manufacturer,

helped the City upgrade 600 street and roadway luminaires.

Solution: Tesla II Luminaire (using STA-41-01, 280W) to

replace 460W High Pressure Sodium with 30% fewer fixtures.

Results> Reduced the number of fixtures from 600 to 420 while maintaining brightness and safety levels> 60% energy savings compared to existing HPS solution> Greatly reduced energy consumption and maintenance resulting in payback of 1.5 years More than $200 annual savings on energy costs per fixture Reduced lamp replacement from 4 to 11 year cycles

> Improved the quality of light from yellow to white light with 2.4X better night time visibility> Dark sky compliant with improved uniformity> Reduced the environmental footprint by 558 tons of CO2 emitted per year
