Given the following scene on the stage Spotlight #1 1 meter diameter Spotlight #2 2 meters diameter Both spotlights SPOTLIGHT#1 and SPOTLIGHT#2 are place at 20 meters from the stage. You want to produce a circle of light of 1meter diameter with the SPOTLIGHT#1and a circle of light of 2 meters diameter with the SPOTLIGHT#2 1) Calculate the BEAM ANGLE of the SPOTLIGHT#1 and SPOTLIGHT#2 2) You want to have an illuminance of 300 lux on Mrs. Pott (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? 3) If the lamp used is a LED lamp with an efficacy of 90 Lumen/Watt, what will be the power of the lamp? 4) You want to have an illuminance of 600 lux on the Beauty and the Beast (under the SPOTLIGHT#2). 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 90 Lumen/Watt, what will be the power of the lamp?

Transcribed Image Text:Given the following scene on the stage
Spotlight #1
1 meter diameter
Spotlight #2
2 meters diameter
Both spotlights SPOTLIGHT#1 and SPOTLIGHT#2 are place at 20 meters from the
stage. You want to produce a circle of light of 1meter diameter with the
SPOTLIGHT#1and a circle of light of 2 meters diameter with the SPOTLIGHT#2
1) Calculate the BEAM ANGLE of the SPOTLIGHT#1 and SPOTLIGHT#2
2) You want to have an illuminance of 300 lux on Mrs. Pott (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?
3) If the lamp used is a LED lamp with an efficacy of 90 Lumen/Watt, what will be
the power of the lamp?
4) You want to have an illuminance of 600 lux on the Beauty and the Beast (under
the SPOTLIGHT#2). 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 90 Lumen/Watt, what will be
the power of the lamp?
