All spotlights are place at 15 meters from the stage. You want to produce a circle of light of 2meters diameter with the SPOTLIGHT#1 on the Player #1, a rectangle of light of 2m by 1m with the SPOTLIGHT #2 on the Player #2 and a circle of light of 1meter diameter with the SPOTLIGHT#3 on the Player #3 1) Calculate the BEAM ANGLE of the SPOTLIGHT#1 and SPOTLIGHT#3 2) You want to have an illuminance of 300 lux on Player #1 (under the SPOTLIGHT#1). What is the Luminous Flux (lumen) the lamp need to releases assuming homogeneous distribution of the light in the illuminated circle? Given the following scene on the stage Player #1 Diameter 2meters ARAN Player #3 Diameter 1meter Player #2 High 2m Width 1m na 3) If the lamp used is a Incandescent lamp with an efficacy of 15 Lumen/Watt, what will be the power of the lamp? 4) You want to have an illuminance of 600 lux on the Player #3 (under the SPOTLIGHT#3). What is the Luminous Flux (lumen) the lamp need to releases assuming homogeneous distribution of the light in the illuminated circle? 5) If the lamp used is a LED lamp with an efficacy of 80 Lumen/Watt, what will be the power of the lamp? 6) You want to have an illuminance of 1000 lux on the Player #2 (under the SPOTLIGHT#2 - the rectangular beam). What is the Luminous Flux (lumen) the lamp need to releases assuming homogeneous distribution of the light in the illuminated rectangle? 7) If the lamp used is a LED lamp with an efficacy of 80 Lumen/Watt, what will be the power of the lamp?
