Transcript Controls & Special Effects

INTD 52
controls—dimming, switching, timers,
photosensors, motion detectors
controls
every room is capable of being viewed and
used in multiple ways
options are almost limitless—need to be
matched to wants & capabilities of client
common mistake: locating majority of controls
at front door…give them options and let them
tell you what they want
switch controls
momentary contact switches (door jam switches)
devices that turn on the light when door is
opened—when door is shut, light is off
good only if clients (and their children) close
the door completely after use
switch controls motion sensors
turns on light as someone enters room—keeps
them on as long as there is movement or for
certain length of time
manual override is available
switch controls panic switches
normally located in master bedroom to turn on
exterior perimeter lights—useful for suspicious
noises or if left on inadvertently
switch controls half-switched receptacles
labor-saving device in houses that use a lot of
portable luminaires
wall switch activates one of the two outlets
and the other outlet is continuously live
should NOT be put on a dimmer
switch controls sound-actuated switches
turn on lights when noise is made—
may find the lights turning on and off at
inopportune moments
low-end solution to
half-switched
receptacles
switch controls three-way switching
confusing
can be turned on from two locations—the
actual luminaire counts as one leg of the
switching chain
switch controls timers
another option for turning lights on and off
add a level of security to a home—come on
at set times or staggered intervals to give the
appearance of someone home
plug-in; 24-hour programmable; 24-hour/7
day programmable
switch controls photosensors
activated by the absence of light—useful in
outdoor lighting
•must keep sensors clean
•locate in shade-free spot
& out of direct path of
another light
switch controls dimmers
allows variable adjustment of light levels
rotary, toggle, glider, touch, low voltage & line
voltage
switch controls dimmers
choose a dimmer specifically made for the
luminaire type you are dimming
be aware of the dimmer’s maximum wattage
(normal 600 watts)—mounting two or more
next to one another decreases load capacities
choose well made dimmers—don’t expect
much from a $4.95 dimmer switch
choose dimmer style to match exisitng switch
plates
switch controls pre-set dimming systems
allow for greater variety of predetermined
light level combinations
have become more affordable
usually used for entertaining spaces—living
rooms, dining rooms, entries & kitchens;
sometimes bedrooms
switch controls
central home lighting control systems
allow for remote control of entire house from
a few choice locations
cost effective only in new construction—radio
controlled components an option for existing
construction
switch controls
bottom line
DO your research
DO NOT overdesign the controls—must be
user-friendly for specific client
participation activity:
reading lighting plans
…as a group, answer the questions on the on
the assignment sheet using the lighting plans
provided
…remember that this is a lesson in plan
navigation as well as a beginning to learning
the lighting language in a more “hands-on”
approach

special effects
special effects
since special lighting effects can have such a
strong presence—picking the right placement
is MAJOR factor
should be subtle and controllable in residential
applications for everyday use
special effects framing projectors
optical framing projectors—focus light to
match the shape of the art/table it illuminates
•simpler models—use a series of shutters
•sophisticated models—custom-cut metal
template to match shape of art
special effects framing projectors
•need regular adjustments if movement in
building—kids, traffic nearby, etc…
• housing needs to be accessible—ok if attic
space above but what about bedroom?
•cost around $1500…simpler recessed
adjustable MR16 around $165
special effects neon
hardwired installation not allowed in
residences—3000-15,000 volts
portable is legal & safe
glass vacuum tube
filled with neon
gas—electricity
causes orangered glow
special effects neon
special effects neon
special effects neon
special effects cold cathode
close relative of neon—used for illumination
purposes, not as signage or art
transformers can operate at less than 1,000
volts—inspectors will look for UL label
small in diameter compared to fluorescent—
great for cove lighting or behind crown
molding
special effects cold cathode
special effects fiber optics
comes in edge-lit & end-lit varieties
usually contains two components: the fiber
optic material itself & the illuminator
special effects fiber optics
illuminator box—
•remotely located
•houses lamp, ballast & fan
•could house optional color wheel or filter
pros:
•flexibility—changes color at will
•ease of installation—can be used in water
•low maintenance
cons:
•not as much light as neon
special effects fiber optics
special effects LEDs (light-emitting diodes)
relatively new on the market—available in
colors as well as white
400,000 hours of life
used in:
•cove lighting or any indirect, ambient
installation
•bookcases or cabinets
•under cabinet lighting…

bottom line
a little goes a long way
