17
Q

It is composed of a tubular glass bulb that is covered with a thin phosphor coating on it’s inside surface.

A

Fluorescent Lamps

18
Q

Are commercially available in straight, U-shaped of circular tubes in a variety of sizes, wattages, voltages, colors, and types of base.

A

Linear fluorescent lamps (LFL)

19
Q

Offer higher light (lumen) output in comparison to standard output fluorescent lamp. It consume more power and have significantly lower efficacies.

A

High Output (HO) and Very High Output (VHO) Fluorescent Lamp

20
Q

Miniaturized fluorescent lamps manufactured with integral ballast and a standard screw base that can be installed in a standard light fixture in place of incandescent lamps.

A

Compact Fluorescent Lamps (CFL)

21
Q

The ________ blend in a fluorescent lamp determines the color temperature and color rendering of the light emitted by the lamp.

A

phosphor

22
Q

Are the most popular, least expensive, and lowest quality phosphors.

A

Halo phosphors

23
Q

The ratio of light (luminous flux, in lumens) emitted by a fluorescent luminaire to the electrical energy consumed, including the ballast.

A

Luminaire Efficacy Rating (LER)

24
Q

It produce a very bright light by discharging an arc.

A

High Intensity Discharge Lamps

25
Q

One of components of HID lamps that contains the fill gas.

A

Internal arc tube

26
Q

One of the components of HID lamps that surrounds the arc tube to avoid shattering that could result from direct contact with water and other fluids.

A

Large outer glass bulb

27
Q

These are the first commercially available HID lamps.

A

Mercury Vapor Lamps

28
Q

Are constructed similar to MV lamps except that it has various metal halides added to mercury and argon in the glass fill. It offers much better efficacy and color rendention.

A

Metal Halide Lamps

29
Q

It contain an internal arc tube made of translucent ceramic material rather than quartz glass because of the high temperature.

A

High-Pressure Sodium Lamps

30
Q

Are a blend between HID and fluorescent technologies. It produces a monochromatic yellow light consisting almost entirely of orange-yellow wavelengths.

A

Low-Pressure Sodium Lamps

31
Q

A restart delay called the __________ of one to several minutes is needed before the low-pressure sodium lamp reaches its peak output.

A

restrike time

32
Q

Combine the luminous efficiency of an HID lamp with the good color rendering capability of an incandescent lamp. It has no start time and thus total luminous flux is available immediately.

A

Blended Lamps

33
Q

They are directly interchangeable with incandescent lamps and have a longer lamp life but they cannot be dimmed.

A

Mercury-Tungsten Blended Lamps

34
Q

It refers to a type of lighting that uses light-emitting diodes (LEDs), organic light-emitting diode lights (OLEDs), or polymer light-emitting diodes (PLEDs).

A

Solid-State Lighting

35
Q

Semiconductor that consists of a chip of semiconducting material treated to create a structure with two electro charged electrons.

A

Light-Emitting Diodes

36
Q

Based on aluminum gallium arsenide (AlGaAs).

A

Red LEDs

37
Q

Are from indium gallium phosphide (InGan)

A

Blue LED

38
Q

Are from aluminum gallium phosphide (AlGaP)

A

Green LEDs

39
Q

White light can be achieved with LEDs in two main ways.

A
  1. Phosphor conversion
  2. RGB systems
40
Q

____________ in which a blue or near-UV chip is coated with phosphor(s) to emit white light: and ______________ in which light from multiple monochromatic LEDs is mixed, resulting in white light.

A

Phosphor conversion and RGB systems
