1 BASIC ELECTRICS CLASS CLASS WILL TEACH HOW TO IDENTIFY DIFFERENT LIGHTS AND ACCESSORIES HOW TO SAFELY HANG, FOCUS, AND DRESS A PIPE HOW TO READ PLANS AND PAPERWORK BASIC ELECTRICITY

2 PARTS OF A FIXTURE

3 Ellipsoidal Reflector Spotlight Produces hard-edge, focusable beam Shutters allow for framing of beam May be used to project steel patterns (gobo), color patterns on glass (glass gobos) or color images on dichroic glass Evenness of field depends on lamp position within reflector (bench focus) Long through makes them suitable for FOH applications. Labeled by either beam spread (26 deg) or lens width by focal length (6x12)

4 DIFFERENT TYPES OF ERS OR LEKO SOURCE 4 ALTMAN 360 Q ALTMAN SHAKESPEARE ALTMAN 1KL

5 Parabolic Aluminized Reflector Sealed beam lamp contains filament, envelope, reflector, and lens all in one package Wattage dependent on size (max PAR w) Beam dependent on lens Durable, weather resistant Elliptical beam.

6 PARCANS ETC PAR PAR 64 PAR 56PAR 46

7 TYPES OF PAR LAMPS ACL (Aircraft Landing Light) NSP (Narrow Spot) MFL (Medium Flood) WFL (Wide Flood)

8 ETC PAR LENSES

9 Fresnel Spotlight Uses Fresnel lens to focus light Uses a spherical reflector Distance between lamp / reflector and lens determines beam width (adjustable spot/flood) Produces soft light Very common on movie and TV sets

10 FRESNELS ALTMAN 6 FRESNEL ALTMAN AF FESNEL ALTMAN 8 FRESNEL ARRI 1000

11 PARNel CROSS BETWEEN PAR AND FRESNEL TWO LENS THAT TWIST TO CHANGE BEAM SIZE KNOB ON BOTTOM TO SPOT/FLOOD LIKE FRESNEL SAME BODY AS ETC PAR

12 STRIP LIGHTS AND CYC LIGHTS USED TO LIGHT DROPS AND CYCLORAMAS PROVIDE EVEN WASH LIGHT FOR CYCS AND DROPS USUALLY HUNG FROM BATTENS OR PLACED ON FLOOR (ground row) COME IN MULTIPLY CELLS AND CONFIGUATIONS USUALLY HEAVY AND LONG (2 man lift) REFLECTOR SHAPE AND POSITION MATTER TO BEAM SPREAD

13 CYC LIGHTS T-3 STRIP LIGHT BROAD CYC SKY CYC

14 MOVING LIGHTS ALSO CALLED INTELLIGENT LIGHTS, AUTOMATED, OR MOVERS 2 TYPES - MOVING MIRROR AND MOVING YOKE FIRST APPEARED IN 1979 ON GENESIS TOUR USE ELECTRIC MOTORS TO FOCUS/POINT, CHANGE COLOR AND CHANGE TEMPLATES, ZOOM, AND EDGE/FOCUS MOST USE DISCHARGE LAMPS, NO DIMMERS NEEDED

15 MOVING LIGHTS MOVING MIRROR MOVING HEAD

19 LEDs L.E.D.- LIGHT EMITTING DIODE ELECTRONIC PART THAT EMITS A CERTAIN WAVE LENGTH OF LIGHT(COLOR) WHEN ELECTRICITY FLOWS THROUGH IT USUALLY USED AS AN UPLIGHT,CYC, AND A WASH LIGHT GETTING BRIGHTER AND DOING MORE EVERY DAY USES LESS POWER GENERATES LESS HEAT

21 LIGHTING ACCESSORIES HARDWARE USED TO HANG OR ALTER HOW LIGHT COMES OUT OF UNIT USUALLY PLACED IN OR INFRONT OF FIXTURE GEL- DEEP DYED POLYESTER THAT IS COLORED PUT IN FRONT OF FIXTURE TO CHANGE COLOR OF LIGHT

22 LIGHTING HARDWARE 1 TOP HAT SIDE ARM HANGING IRON CLAMP TO CLAMP

23 LIGHTING HARDWARE 2 RIGID CHESEBORO SWIVEL CHESEBORO BOOM BASE RING TOP

24 LIGHTING HARDWARE 3 FULL SCENERY BUMPERDROP IN IRIS TEE BARN DOOR

25 HARDWARE 4 TEMPLATE HOLDERS COLOR FRAMES GEL SWATCH BOOK STEEL TEMPLATE

26 PHOTOMETRICS DATA USED TO DESCRIBE THE PERFORMANCE OF LIGHTING INSTRUMENTS, SPECIFICALLY THEIR INTENSITY AND BEAM SPREAD

27 COLOR TEMPERATURE Color temperature is a characteristic of visible light, that has important applications in lighting. Color temperature is conventionally stated in the unit of absolute temperature, the kelvin, having the unit symbol K. visible lightkelvin Color temperatures over 5,000K are called cool colors (blueish white), while lower color temperatures (2,700–3,000 K) are called warm colors (yellowish white through red).[1][1]

28 COLOR TEMPERATURE COLOR TEMP IS RELAVENT TO HOW COLORS AND PEOPLE LOOK THE SUN IS ROUGHLY 5600k (COOL BLUE WHITE) INDOOR LIGHT BULBS ARE APPROXIMATELY 3050k (WARM REDDISH WHITE) FLOURESCENT BULBS ARE ROUGHLY 4400k (GREENISH WHITE) MOVING LIGHT LAMPS ARE 5600k (COOL BLUE WHITE LIGHT) STAGE LIGHTS ARE 3200k (WARM ORANGE WHITELIGHT) COLOR TEMPERATURE HAS NOTHING TO DO WITH HOW HOT THE FIXTURE GETS THE WAY WHITE LIGHT LOOKS IS RELATIVE TO ITS COLOR TEMPERATURE AND CAN BE COMPARED TO A RAINBOW, IT FOLLOWS TO SAME COLOR ORDER AS FAR AS THE QUALITY OF WHITE LIGHT

29 BASIC ELECTRICITY ELECTRICITY IS THE FLOW OF AN ELECTRIC CHARGE/CURRENT ELECTRICTY IS MEASEURED IN 4 CRITERIA: VOLTAGE- PRESSURE OF ELECTRICTY IN A CIRCUIT - MEASURE OF ELECTRICAL POTENTIAL AMPERAGE- AMOUNT OF ELECTRICY IN CIRCUIT - MEASURE OF ELECTRICAL CURRENT RESISTANCE- THE RESISTANCE TO ELECTRIC FLOW IN A CURCUIT, MEASURED IN OHMS WATT- HOW MUCH POWER IS USED THE COMMON FORMULA FOR THIS IS: WATTS=VOLTAGE x AMPERAGE

30 BASIC ELECTRICITY ELECTRICITY IS TRANSMITTED IN 2 WAYS AC OR DC DC- DIRECT CURRENT AC- ALTERNATING CURRENT DC- IS BEST DESCRIBED AS BATTERY POWER AC- IS THE ELECTRICITY IN YOUR HOME OR OFFICE IN THE UNITED STATES WE USE 120/208V OR 277/480V POWER AT 60 HERTZ MOST LIGHTING FIXTURES ARE EITHER 120V OR 208V DO NOT TOUCH ANYTHING RATED 277V OR 480V

31 BASIC ELECTRICITY OHMS LAW E=IR E IS VOLTAGE I IS AMPERAGE R IS RESISTANCE W OR P IS POWER(WATTS) WHEN YOU KNOW 2 OF THESE VARIABLES YOU CAN FIGURE OUT WHAT YOU NEED TO KNOW

32 120 VOLT CONNECTORS STAGE PIN STRAIGHT BLADE OR EDISON TWIST OR LOCKING CONNECTOR

33 208 VOLT CONNECTORS STRAIGHT BLADE 208V CONNECTOR L V TWIST LOCK CONNECTOR

34 SINGLE POLE LOCKING CONNECTOR COMMOMLY CALLED CAM-LOCS MUST LOCK BY MATING AND TURN A QUARTER TURN USED FOR FEEDER CABLE

35 MULTI CABLE CARRYS 6 CIRCUITS OF POWER ALSO CALLED SOCAPEX OR VEAM CABLE NEEDS BREAK OUTS AND INS TO SPLIT INTO INDIVIDUAL CIRCUITS

36 DATA CONNECTORS ETHERCON 3-PIN XLR 5-PIN XLR DMX

37 DIMMERS CONTROLS HOW BRIGHT(INTENSITY) A CONVENTIONAL LIGHTING FIXTURE IS ON A SCALE OF 1% TO 100%

38 POWER AND DATA FLOW
