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 controlsmomentary 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 tohalf-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
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 tubefilled with neongas—electricitycauses orange-red glow
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 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 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…
