PARTS OF A FIXTURE

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)

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

PHOTOMETRICS

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

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.

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]

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

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

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
