AMKO SOLARA LEP
At AMKO SOLARA we use advanced lighting technology at the core of every luminaire to provide superior lighting
performance in a highly e�cient, intelligent, and durable design. Some technology highlights include:
Light Emitting Plasma (LEP) - Plasma is a high-intensity light source that shares the same bene�ts as LED, like longevity
and reliability, but has a much greater lumen density (up to 200x greater) and can distribute light evenly across wide
areas. LEP uses a solid-state driver and a responsive emitter con�guration to provide advanced dimming capabilities
through digital or analog control. Our LEP luminaires deliver energy savings while providing an improved quality of light
for enhanced visibility, safety and security. LEP is best used for high illuminance applications at heights above 25 feet. See
our LEP FAQ for additional information.
Improved Color Recognition - Our LEP series o�ers a full spectrum light source and delivers better color recognition than
competing HID products which translates into brighter colors and a warmer, more inviting work environment.
Key Bene�ts
High Mast Lighting‧Energy Savings: LEP luminaires scale to high lumen output needed for high mast lighting without sacri�cing
e�ciency and lifetime as LED and HID sources do. LEP saves up to 75% energy while producing equivalent visibility.
‧Long Life: LEP sources last 3-5 times longer than HPS sources, reducing costly maintenance at poles as high as 100ft in
the air. LEP luminaires provide tremendous maintenance savings as well as mission-critical reliability for ports, airports,
and industrial yards.
‧Light Quality: The full color spectrum provides a greater than 2x advantage over HPS in nighttime visibility.
Roadway Lighting‧Cost of Ownership: LEP's luminaire e�ciency and 50,000-hour lifetime combine to o�er the lowest cost of ownership
for roadway lighting when compared to 250W or higher HPS systems.
‧High Lumens Package: Even more cost e�ective as you scale to higher light levels without sacri�cing energy
e�ciency or increasing the weight of the luminaire.
‧Light Distribution: Maximize pole spacing and achieve uniform illumination and luminance distributions using optics
tailored to LEP's single point source.

APPLICATION / BRIEF
How LEP Technology Works LEP light sources create a light-emitting plasma by coupling RF (radio-frequency) energy into an electrode-less quartz lamp� The RF energy is created and amplified by an RF circuit that is driven by a Solid-State Power Amplifier� The following three
steps outline the process of light generation in all LEP systems:
Step 1:
An RF circuit is established by connecting an RF power
amplifier to a ceramic resonant cavity 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
ionizes the gasses inside the lamp (purple glow)�
Step 3:
The ionized gas in turn heats up and evaporates the metal-halide
materials which form a bright plasma column within the lamp (blue to
bright white light)� This plasma column is centered within the quartz
envelope and radiates light very efficiently� In the back side of the lamp,
a highly reflective powder is used to reflect nearly all of this light in the
forward direction�

Bulb Thermodynamics and Lifetime ConsiderationsThe LEP emitter design aims to maintain an optimal thermodynamic power balance that enables the highest
plasma output while keeping the lamp wall under a safe operating temperature� The total RF power into
the emitter, P in, is balanced with the radiated optical power, P radiated, and conducted heat by the puck, P
conducted� The lamp chemistry or fill and the geometry are the main parameters used to optimize luminous
flux while keeping the lamp wall temperature below 1100 Kelvin or 827 Celsius� A halide pool gathers at
the coldest spot of the lamp replenishing the plasma through a reversible phase change process during its
entire lifetime�
At the designed vapor pressures and quartz temperatures, devitrification and wall whitening processes
are rare resulting in a long-lasting lamp� A properly designed lamp operating at its specified environment
eliminates catastrophic lamp failures� It should be noted that the LEP lamp does not contain metal
electrodes as a typical HID lamp� Electrodes are the primary cause of failure in such systems where electrode
wear-out, wall darkening from sputtered electrodes, and cracking of quartz-metal seal are common� LEP
emitters do not display any of these failure modes� It is also worth noting that a significant amount of
energy (>20%) in HID lamps are wasted in heating electrodes where this energy is used to create light in a
LEP system� Therefore, the LEP emitter is inherently much more robust and efficient compared to traditional
HID lamp systems�
At steady state, the gases (Ar, Hg, metal halides)
are in local thermodynamic equilibrium�

Environmental ConditionThe lamp performance is stated for the following environmental conditions:
• At ambient temperatures higher than 45 C, the driver temperature can exceed its recommended limits which will impact its long term reliability� In order to operate for long periods of time at elevated ambient temperatures, the LEP driver must be heat sunk more thoroughly and its base temperature validated at the elevated temperatures� The RF cable is rated for up to 105 C temperature surrounding and therefore should not exceed this limit if operating in higher ambient temperatures�
• At ambient temperatures lower than -40 C, start time becomes longer and can exceed the specification for the system� Though there is no specific impact on lifetime or reliability at cold temperatures, the lamp may experience difficulty in igniting or warming up to full brightness in the allotted time� See page 13 for the impact of ambient temperature on start up times�
• The bare LEP system outside of a light fixture is not IP rated� The fixture should be designed such that water and moisture are kept out of the lamp area as much as possible� Standard sealing principles for outdoor fixtures apply to LEP fixtures� Please refer to the LEP Fixture Design Guide for further information�

DVT/HALT SummaryThe following Design Verification Test (DVT) of LEP STA-40 lamps was performed in accordance
with mil and ETSI (telecommunications) standards for outdoor products to simulate extreme
environmental and mechanical conditions� The tests, unless otherwise stated, were done to the
bare lamp system and not in a light fixture� Some of the indicated testing were performed in a
mock up fixture that prevents direct moisture from forming on the lamp�
The lamps also were subjected to Highly Accelerated Life Testing (HALT) by
increasing stress levels to induce failures in order to identify the weak points in the
design� The lamp systems were subjected to increasing temperature, vibration,
and power stresses while operating� The reported values are the limits where the
lamp operated without any damage�

Lumens/CCT Versus TemperatureThe following data depicts the variation in light output and CCT change over the entire
ambient operating temperature range from -40° to +45° C� There is a maximum of -3% lumens
penalty at hot temperatures and a +100 kelvin color shift at cold temperatures� The lumens
decrease is a result of RF amplifier inefficiency at hot and the color shift is due to decreased
lamp cold spot temperature�

Electrical Profile Ignition and Warm-UpThe following data shows the current profile that the RF driver draws during its
warm up process� It is typical for the RF amplifier to draw as much as 14 amperes
from the DC power source� Therefore, the DC power source must be chosen such
that it does not have a cut off below 14 amperes�

MTBF SummaryMTBF (mean time before failure) is a basic measure of reliability for repairable
electronic assemblies� It is calculated as T/N where T is the total operating time
and N is the number of catastrophic failures� MTBF calculations do not reflect
parametric failures where electrical or optical output decreases beyond the
specified parameter� In a lighting system, parametric failures are shown by lumen
and CCT maintenance plots (see page 19 Lumen Maintenance)�
Catastrophic failure rate over time of the RF driver follows a typical bathtub curve
observed in many electronics assemblies� There are three distinct periods in the
bathtub curve that describes the failure rate over time� First period is characterized
by decreasing failure rate and occurs in early life due to infant mortality� This
period is relatively short and the weaker units die off leaving a population of more
rigorous units� To ensure that the weaker units are not released, LUXIM performs
burn in and power cycling of lamp systems� In addition, LUXIM uses components
that are rated for significantly higher temperature than actual use condition� The
next period characterized by a low but constant failure rate where the failures are
random in nature� This is the period of useful life of the RF driver where MTBF and FIT
calculations apply� The last period is characterized by an increasing failure where
components wear out due to physical, electronic, and thermal stresses over its
lifetime� MTBF calculations are no longer valid in this period�

MTBF Study DetailsIn the period of useful life, the failure rate, R(t) can be computed as R(t)=e-λt
whereλis =1/MTBF and t is the operating time� The probability of catastrophic failure is
simply P(t) = 1- R(t)�
The MTBF calculations for the STA-41 RF driver are performed using MIL-STD-217
techniques� There are several factors that determine reliability including:
» Temperature of operation
» Stress levels of the components
» Time in production (learning curve)
» Quality level of the components
» Operating environment
The system MTBF calculation is done using data from actual testing by component
manufacturers and historical performance of the components� The following conditions
were assumed:
» 85º C base plate temperature
» Learning curve of < 1 year
» COTS quality level (commercial off the shelf )
» Ground, Fixed (not directly exposed to the outer environment)
» Typical and Maximum stress levels
With these assumptions, the LEP RF Driver has an MTBF of 151,000 hours at maximum stress levels and
212,000 at typical stress levels� This corresponds to a 28% and 21% failure rate at the specified 50,000
hours� In a properly designed light fixture, 79% survival at the end of life is typical�

Accelerated TestingOne method of accelerating the failure mechanism of RF drivers is to power cycle
the lamp system� Power cycling introduces the most stress on the RF electronics
due to unfavorable load conditions, higher current spikes, and rapid thermal
change�
Below is the measured survival rate over time due to rapid cycling of STA-41 series
lamps (10 minutes ON/15 minutes OFF)� LEP drivers sustained greater than 8000
power cycles with greater than 90% survival rate� This is equivalent to more than
20 years of operation�

Notes on Lumens Maintenance and CCT ChangeLumens and CCT maintenance for the STA-41 lamp is extrapolated from measured data of the
previous generation of emitter design (STA-40)� STA-41 lamps are expected to perform similar
or better as they use the same lamp chemistry and have an even lower wall loading (power
input/inner surface are of lamp) and hence lower thermal stress that the STA-40 emitter� The
lifetime of the LEP-STA-41 plasma systems are defined as the time to 70% lumen maintenance
of L70� Below are some notes on the lumen maintenance testing:
1� Lumen maintenance is extrapolated from actual lamp (emitter + driver) data
of 5000 hours� As data is updated every 1000 hours, LUXIM will continue to
update the extrapolation�
2� Seasoning period of first 300 hours is eliminated in order to extrapolate the
lumen maintenance end of life�
3� Lumens are measured in an integrating sphere following closely to IESNA LM-
79 standard 2π measurement geometry�
4� Test conditions are as follows:
» 30º C room temperature
» Constant current and voltage
» Emitter oriented vertical down
» Benchmarking at 1000 hour intervals

Field Trial DataIn order to validate predictions for lumen and CCT maintenance based on life test data
(pages 17 and 18), LUXIM continually monitors field trials� Field trials are the most unbiased
data set that captures degradation in not only the light source but also in the optics,
electronics and thermal management of the fixture�
Below is the measured performance of light fixtures using STA-41-01 light source in outdoor field trials� This
trial consists of 12 cobra head light fixtures on a 12 hour ON/12 hour OFF cycle�
