Conduits

are circular raceways used to enclose wires and cables and are of metal or plastic (PVC).

Panel Box / Board

Per panel = 12-16 light fixtures can max up to 30 but low wattage

Outlets

A point on the wiring system at which current is taken to supply utilization equipment. Refers to the entire box assembly

Receptacles

The wiring device in which the utilization equipment (appliance) cord is plugged into.

Kinds of Outlets

1) Convenience Outlet or Attachment Cap

2) Lighting Outlet

3) Receptacle Outlet

Switches

Devices for making, breaking or changing conditions in an electrical circuit under the conditions of load which they are rated.

Wiring Switches

1) General Purpose Switches - single or double pole switches

2) Three way Switch - control 2 different points

3) Four way Switch - 3 wire switches

4) Electrolier or Multi-circuit Swirches - control lights in multi-lamp fixtures

5) Momentary Contact Switches - connect or cut-off a circuit for only short duration

6) Dimmer Switch - device for regulating the intensity of an electric light

Fuse

Is a device consisting of an alloy link of wire with a low melting temprature which is inserted in the circuit, in such a way, that all current which passes through the circuit, must also pass through this metal.

Circuit Breakers

An over-current protective device designed to function as a switch

Lighting Track

a factory-assembled channel with conductors for one to four circuits permanently installed in the track that will act as light duty (branch circuit) plug-in busways.

Lumens

Unit of light (or luminous flux)

Footcandle

Unit of density of light amount of lumens falling on an area 1sq.ft. 1ft away

Lux

Amount of lumens falling on an area 1sqm 1m away. 1footcandle = 10.76 lux

(CP) Candlepower

Unit of light intensity

(FL) Footlambert

Unit of brightness

Incandescent Lamp

Composed of a sealed glass containing a filament connected at its ends to the contact area in the base thereby completing an electronic circuit

R&Par Lamps

Complete optical systems in a single bulb. The bulb contains a filament, reflector & lens

Tungsten Halogen Lamps

also called quartz or quartz-iodine; lamps use a halogen gas cycle to prevent rapid depreciation of the lamp filament and darkening of the transparent envelop

Flourescent Lamps

Comprises a cylindrical glass tube, seales at both ends & containing an inert gas usually argon & mercury vapors

Mercury Vapor Lamps

contains mercury vapor in a clear quartz arc tube, which when electrically excited, produces visible light of characteristically blue-green color. It is suitable only for limited industrial areas, general outdoor applications and street lighting.

Metal Halide Lamps

a modification of the mercury vapor with an arc of improved color. In addition to mercury, the arc tube contains metallic vapors such as indium iodide, thallium iodide, or sodium iodide. It possesses therefore increased light output, improved color rendition without the use of phosphors, and small source size.

Ballasts

are auxiliary equipment for fluorescent and HID lamps which limits the amount of current in the lamp and provides the proper starting voltages.

Classification of Luminares

1) Indirect - 90%-100% of light output directed towards ceiling

2) Semi-Indirect - 60%-90% of light directed upwards 40%-10% downwards

3) General Diffuse or Direct-Indirect - equal distribution of light

4) Semi-Direct - 60%-90% of light is directed downwards 40%-10% upwards

5) Direct - 90%-100% of the light output is directed downward

Lighting Systems

1) Cornice Lighting - shielded by a panel parallel to the wall distribute light downward

2) Cove Lighting - shieled by a ledge

3) Valance Lighting - shielded by a panel parallel to the wall distribute light both upward and downward

Absorption

Loss of light when light rays strikes or traverse any medium.

Diffuse Reflection

A beam of light reflected diffusely.

Specular Reflection

A beam of light is specularly reflected.

Reflectance

"Reflection factor" the ratio of light reflected by a surface to the light falling upon it

Transmission

Passage of light through a medium

Transmittance

"Transmission factor" the ratio of light transmitted to light striking the surface

Accent Lighting

Lighting that emphasize a space or an object

Down Light

Concentrated direct lighting from a single bulb

High Hat

"can" type of recessed incandescent downlight

Eye Ball

Lighting unit with a rotating spherical element

Lumiline

a tubular fluorescent lamp with a disc base at each end.

Luminance Ceiling

a false ceiling of diffusing material with light sources mounted above

Filter

Device which changes either amount or color or both

Dimmer

a device to control the amount of light by reducing the voltage or the current; also called a "rayostat".

Capacitor

Electric component which consist of conducting plates insulated from each other by a layer of dielectric material. Usually measured in farads or microfarads.
