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 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

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 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…
