Controls (Updated 2023)

Question 1

How can you control light?

Answer 1

1. Auxillary controls
2. control/direct the light emitted from the luminares
   human controls/interference between operator and source of light

Question 2

____ is the most common and beneficial form of “control” other than turning the luminare on and off

Answer 2

dimmin

Question 3

what does Dimming do?

Answer 3

saves energy
save money
can be integrated into a smart system (dependent system)
can provide sense of individual control (autonomous system)

Question 4

this is a definition of? the quality or state of being-self governing especially the right of self-government. self directing freedom and especially moral independence

Answer 4

Autonomy/autonomous

Question 5

What are the 3 primary “being the scenes” pieces of equipment that are essential in the control of light

Answer 5

Transformed (low voltage incandescent)
Ballast (Discharge/Flourescent)
Driver/Controller (LED)

Question 6

These are qualities of what type of Auxiliary control components?
typically for incandescents/filament sources.
steps down standard building service (120v) to 12v
typically located integral with fixture or remotely
2 types- Magnetic and Electronic

Answer 6

Transformers

Question 7

These are qualities of what type of Auxiliary control components?
Typically used with flourescent/discharge sources
control device used with all discharge lamps
starts with a lamp and controls electrical current
power factior= efficiency of ballast in converting building power
lamp ballast system efficiency= ballast to lamp efficiency
ID’s must be aware of these but not involved in the specification

Answer 7

Ballasts

Question 8

These are qualities of what type of Auxiliary control components?
a self-contained power supply which has outputs that are matched to the electrical characteristics of the LED
provides constant current to LEDs
can be either AC(standard voltage) or DC(low voltage)
allows LEDs to be dimmed. DC can go to 0-100%
RGB drivers also control color changing

Answer 8

Drivers

Question 9

What are some examples of basic physical equipment for lighting controls?

Answer 9

switches
dimmers
timers
occupancy sensors
photosensros
central controls

Question 10

whata re the 2 basic types of dimmers?

Answer 10

Autotransformers and Solid state

Question 11

____ changes the line voltage into low voltage. common but low tech

Answer 11

Autotransformer

Question 12

___ ___ is the most common. use higher technology to control electrical current. Adaptable to various forms of digital lighting controls

Answer 12

Solid State

Question 13

___ ___ ___ ___allow you to control any lighting load from an location

Answer 13

Whole Building Control Systems

Question 14

___ ___ (____) will give you control over a few zones in an immediate area

Answer 14

Local Controllers (smaller)

Question 15

What criteria should you consider when specifying lighting controls?

Answer 15

Energy considerations
economics
aesthetics
UX Design- ease of use

Question 16

What is Load Shedding?

Answer 16

is reducing the electrical needs of a space. such as reducing illumination during peak times is a form of load shedding

Question 17

_____ detects the amount of illumination and then control light by switching lights on and off or by adjusting illumination levels. Often used for daylight integration application and research indicates energy savings

Answer 17

Photosensors
