AND THE ANSWER IS…


IT CAN BE DONE!



HOW MUCH MONEY YA GOT
?



FROM WHICH BUDGET?



THE PROGRESS OF LED TECHNOLOGY
HAS MADE THIS A VALID QUESTION


IMPROVED LIGHT OUTPUT



RGBAW AND MORE



HOMOGENIZED BEAM



REDUCED MATERIAL COST



FOCUS

ON LUMINAIRE DESIGN



FINDING THE HOLY GRAIL




WHY LED IN THEATRE?


REDUCING POWER DENSITY IS NOT THE DRIVING
FORCE AS IN ARCHITECTURAL LIGHTING; DUTY
CYCLE IS GENERALLY NOT THERE
-

STAGE
LIGHTING IS NORMALLY EXEMPTED BY ENERGY
CODES



OPERATIONAL ADVANTAGES
OF LED ARE THE
DRIVING FORCE FOR ADOPTION IN
ENTERTAINMENT LIGHTING AS MUCH AS
PAYBACK ISSUES, MAYBE MORE SO

OPERATIONAL ADVANTAGES


No re
-
lamping means greater reliability, key halogen
lamps in a theatre are still 300 hours life!!


No
expendable

color media
hassle
,
gels

burn

out


Unlimited color selection, cue by cue


Fewer lighting sources required


Can use home made gobos


Cooler, therefore safer fixtures


Much more flexibility from a fixed repertory light plot
than a similar plot using conventional instruments


Fixture by fixture control, regardless of circuiting


The major traditional theatrical
lighting instrument types now have
LED counterparts

WASH LUMINAIRES


USED FOR COLOR WASHES



TRADITIONALLY PARS OR FRESNELS



ONE OF THE FIRST TYPES TO HAVE A VIABLE LED
EQUAL



RGB IS ACCEPTABLE HERE


Border Lights


STILL USED FOR COLOR TONING AND
SOMETIMES FOR LIGHTING BACK DROPS



TRADITIONAL SOURCES ARE HUGE WATTAGE
HOGS



TRADITIONAL FIXTURES HAVE “PAR
-
LIKE”
DISTRIBUTION
-

EASY FOR LED



SATURATED COLORS PREFERRED
-

EASY FOR LED

CYC LIGHTS


TRADITIONAL EVOLUTION FROM BORDER
LIGHTS, THINK WALL WASH FIXTURE,
ASYMETRICAL REFLECTOR



TRADITIONAL SOURCES ARE HUGE WATTAGE
HOGS AND REQUIRE MANY CIRCUITS



SATURATED COLORS PREFERRED
-

EASY FOR LED

AUTOMATED LIGHTING


MANY TYPES EXIST, BUT

THE WASH
LUMINAIRES NOW HAVE VIABLE LED
EQUALS



TRADITIONAL SOURCES ARE HID
-

VERY
HIGH LAMP COSTS, MAINTENANCE ISSUES



SATURATED COLORS PREFERRED
-

EASY
FOR LED

“PROFILE” SPOTS (ERS)



THE HOLY GRAIL, JUST NOW COMING ON THE MARKET FROM MANY
MANUFACTURERS



HARD EDGE SOURCE WITH INTERNAL FOCAL POINT, TRADITIONALLY
ACHIEVED WITH ELLIPSOIDAL REFLECTOR



USED FOR FRONT LIGHTING, LONGER THROWS AND PATTERN PROJECTION
THE WORK HORSE IN EVERY THEATRE



ACHIEVING THE REQUIRED BEAM CHARACTERISTICS HAS BEEN A
CHALLENGE



USED TO LIGHT ACTING AREAS
-

PASTELS AND FLESH TONES ARE MORE
IMPORTANT THAN SATURATED COLORS
-

THIS REQUIRES RGBA OR RGBAW

HOUSE LIGHTS



FULL RANGE DIMMING REQUIREMENTS HAVE DICTATED HALOGEN SOURCES



HOUSE LIGHTS ARE TYPICALLY VERY DIFFICULT TO SERVICE



HALOGEN SOURCES DRIVE THE NEED FOR DIMMER CABINETS THAT OTHER
-
WISE MIGHT NOT BE
NECESSARY



THERE ARE NOW LED SOURCES AVAILABLE FOR HIGH CEILING APPLICATIONS THAT ALSO
INCORPORATE FULL RANGE DMX DIMMING



0
-
10 VOLT OR ELV DIMMING MAY BE ACCEPTABLE IN CAFETORIUMS OR OTHER VENUES WHERE
FULL DIMMING IS NOT AN EXPECTATION



SOME FIXTURES TAKE ADVANGE OF RGBW TECHNOLOGY TO ALLOW HOUSE LIGHT COLOR
-
MIXING



DMX CONTROL ALLOWS FLEXIBILITY IN CONTROL ZONES MUCH THE SAME WAY DALI AND
ADDRESSABLE BALLASTS ALLOW IT IN ARCHITECTURAL LIGHTING

HOW DOES LED AFFECT

SYSTEM DESIGN?


THIS IS NOT YOUR DADDY’S
STAGE LIGHTING SYSTEM


WE ARE ON THE EDGE, OR
MAYBE PAST, A SEISMIC SHIFT
IN SYSTEM DESIGN


IS YOUR PROJECT A
CANDIDATE TO MAKE THE
LEAP?



TRADITIONAL
SYSTEMS


CENTRALIZED DIMMER RACK
FEEDING DISCREET CIRCUITS


CIRCUITS ARE DISTRIBUTED
BASED ON THE NEED FOR
CONTROL FLEXIBILITY AS MUCH
AS LOAD REQUIREMENTS


QUANTITY OF CIRCUITS OFTEN
DROVE FEEDERS TO LARGER
SIZES OUT OF LINE WITH
ACTUAL LOADS



WHAT IS DIFFERENT
WITH LED?


SMALLER FEEDS


REDUCED NEED FOR
CONVENTIONAL DIMMING


NEED TO TURN POWER SUPPLIES
OFF
-

PHANTOM POWER ISSUES


WHERE DIMMING IS REQUIRED IT
CAN BE ACCOMPLISHED USING
DISTRIBUTED DIMMING DEVICES


NO NEED FOR K
-
RATED
TRANSFORMERS


REDUCES LOAD ON AIR
-
CONDITIONING SYSTEMS



CONTROL IS KEY


EACH FIXTURE AND ITS ATTRIBUTES ARE
CONTROLLED DISCREETLY VIA DIGITAL
SIGNALS, TYPICALLY DMX


DMX DATA NEEDS TO BE DISTRIBUTED
THROUGHOUT THE SPACE THROUGH
THE USE OF SPLITTERS OR ETHERNET


EACH FIXTURE CAN TAKE MORE THAN A
DOZEN CHANNELS OF CONTROL


CONTROL CONSOLES EXIST TO MAKE
CONTROLLING ALL OF THIS EASIER



WHAT ABOUT THE DOLLARS?


SEVERAL FACTORS TO CONSIDER



LUMINAIRE COST



REDUCTION OF DIMMING EQUIPMENT



INSTALLATION SAVINGS



OPERATIONAL COST SAVINGS




LUMINAIRE COST


20


30 % FEWER LUMINAIRES REQUIRED


WASH FIXTURES:


CONVENTIONAL: $100

REDUCTION OF DIMMING AND RELATED
EQUIPMENT

K
-
RATED TRANSFORMERS NOT REQUIRED



ELIMINATION OF DIMMER ROOM



DISTRIBUTED DIMMING AND RELAYS



SMALLER FOOTPRINT



LESS LOAD ON AIR
-
CONDITIONING EQUIPMENT







INSTALLATION SAVINGS


REDUCED LOADS MEAN SMALLER FEEDERS



FEWER CIRCUITS REQUIRED



CAN USE COMMON NEUTRALS
IN SOME
CASES



NEED TO DISTRIBUTE DATA, BUT WE
ARE
ALREADY DOING
THAT



MAY REDUCE THE NEED FOR ACCESS TO
EQUIPMENT

SERVICE LIFE
-

LED


Assume an L70 of 50,000 hours


Assume usage at 6 hours per day, 200 days per year


Life expectancy would be over 40 years!!


Things break before that
-

LED equipment is more
expensive to replace which
m
ust be considered


Annual Operating Savings pays for brand new
equipment in about 15 years at today’s dollars




CONCLUSIONS


Very significant operational advantages to an LED
theatre lighting system


If you have the budget you can do an all LED theatre


Even if you have a “conventional” budget you can
incorporate LED to an extent that is significant enough
to drive your system design


Provide for the future use of LED in your system
design


Distribute Data


Provide Capacity in the Control System


Provide the ability to turn power supplies off





AN ALL LED THEATRE
