A

교류 (AC)

방향이 지속적으로 바뀌는 전류입니다. 주파수는 초당 주기 수인 헤르츠(Hertz)로 측정됩니다. 교류(AC)는 주거용 및 상업용 애플리케이션의 주요 전원 유형입니다. AC 주파수에는 두 가지가 있습니다. 미국(미국 표준을 따르는 국가)의 60헤르츠와 유럽 및 유럽 표준을 따르는 국가의 50헤르츠입니다.

전반 조명

지정된 영역 내부의 조도입니다. 조도 센서는 주변 조도를 감지하여 조명을 자동으로 켜거나 끕니다. 일반적으로 주변 조도 값은 기본적으로 15Lux, 25Lux 및 35Lux로 설정되어 있습니다.

암페어 / AMP

전류의 단위입니다. 1암페어는 1볼트의 전위차에서 1옴의 저항을 통해 흐르는 전류입니다.

B

안정기

안정기(Ballast)는 형광등 조명 시스템에서 램프 및 조명 기구에 충분한 전류와 전압을 공급하고 조절하는 전기 장치입니다. 

전구

A 전구 조명 기구의 소켓에 나사식으로 결합하는 독립형 광원입니다. 일반적으로 유리 또는 플라스틱 돔이 광원 자체(필라멘트 또는 LED)를 덮고 있습니다. 이는 조명 기구와 다르며, 전구가 조명 기구에 나사식으로 결합됩니다.

C

소형 형광램프(CFL)

소형 형광램프(CFL)는 컴팩트 형광등, 절전형 전구, 컴팩트 형광관이라고도 불리며, 백열전구를 대체하기 위해 설계된 고효율 형광램프입니다. 이 램프는 백열전구의 공간에 맞게 구부러지거나 접힌 튜브와 램프 베이스에 탑재된 소형 전자식 안정기를 사용합니다.

전류

회로에서 전기가 흐르는 속도이며, 암페어로 측정됩니다.

D

주광 수집(Daylight harvesting)

관련 필요한 표준을 충족하기 위해 설계자가 지정한 설정 조도 수준을 유지하도록 주변 주광 수준에 따라 조명을 밝히거나 낮춥니다. 주광 수집은 ‘유지 조도(Maintained illuminance)’ 및 ‘주광 모니터링(Daylight monitoring)’으로도 알려져 있습니다.

직류 (DC)

한 방향으로만 흐르는 전류입니다.

디머

조명 기구에 연결되어 광 출력의 세기를 조절하는 전자 장치 또는 시스템입니다. 디머 조명의 밝기를 낮춰 에너지를 절약할 수 있으며 백열등, 할로겐, 저전압 광원의 수명을 연장해 줍니다.

Dual-technology Motion Sensor

Dual-technology motion sensors use two methods to detect motions. In most cases, they use a combination of PIR and ultrasonic technology to provide better motion detection performances. 

F

형광등

A fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. 

G

Ground

A conducting connection between an electrical circuit and the earth or other large conductions body to serve as an earth thus makes a complete electrical circuit.

Ground Wire

A ground wire is an electrical wire that extends into the ground to give excess electrical charges a safe place to go for higher security purposes.

H

Halogen Lamp

A type of incandescent lamp with a small amount of a halogen added to the tungsten filament. The combination of the halogen gas and the tungsten filament redeposits evaporated tungsten on the filament, increasing its life and maintaining the clarity of the envelope.

HVAC

Heating, Ventilation & Air Conditioning.

I

IEC

International Electrotechnical Commission, is an international standards organization that publishes international standards for all electrical, electronic and related technologies.

Illuminance

The “lighting level” measured in foot-candles, which indicates the density of light on a surface per unit area, i.e. how much light is falling on a given area (ft-C = lm/ft2 or lux = lm/m2).

Incandescent Lamp

An electric light with a wire filament that glows and gives off light when heated by an electric current. They are low costs and work equally well on either AC and DC.

IR (infrared)

Electromagnetic waves in the frequency range just below visible light corresponding to radiated heat. IR waves are often used for detecting motions in motion sensors. 

L

Lamp life

Average time of the lamp that is capable of producing light before it fails. Usually, it’s defined as the point in time when 50% of the lamps have burned out.

LED (Light-Emitting Diode)

A semiconductor light source that emits light when current flows through it.  They are 90% more efficient than incandescent light bulbs, extremely long life and produce little heat on object being illuminated.

Line Voltage

The standard 120 V power provided by receptacles and for lighting fixtures in commercial spaces in the United States and Canada.

Luminaire

A luminaire or light fixture is an electrical device containing an electric lamp that provides illumination. All light fixtures have a fixture body and one or more lamps. The lamps may be in sockets for easy replacement—or, in the case of some LED fixtures, hard-wired in place.

M

Motion Detector / Motion Sensor

A motion detector or motion sensor is an electrical device that utilizes a sensor to detect nearby motion, particularly people. Typically, in the lighting control sector, there is PIR technology motion sensor, ultrasonic technology motion sensor and dual technology motion sensor that use a combination technology of both. Motion detectors are also known as ‘presence detectors’.

O

Occupancy Sensor

An occupancy sensor is an indoor motion sensor used to detect the presence of a person to automatically control lights or temperature or ventilation systems. The purpose of using occupancy sensor is to save energy and increase convenience by automatically turning lights on when space is occupied and off when space is vacant.

P

Passive Infrared Sensor / PIR Sensor

A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors.

Photocell

A control agent for fixtures that can automate light levels. Some photocells qualify controls for certain rebates and incentives.

T

Time-delay

If a switch is activated and no movement is detected the lights will switch off after a pre-set time.

U

UL 인증

A product that has been tested and listed by UL.

V

Vacancy Sensor

A device that detects the absence of people in a space and provides automatic switching or dimming of lighting.  The primary purpose is to automatically turn lighting Off when an area is not occupied to ensure energy savings. A vacancy sensor relies on a person operating a manual switch to turn lighting On (Manual On/Auto Off).

전압

The electrical power, in volts, of force/pressure supplied by an electrical circuit to a lighting source. Standard US power supply is 120 V 60 cycle (277 V 60 cycles in commercial spaces). Standard power internationally is 220/240 V 50 cycles. It is conceptually the “pressure” of the power supply similar to the psi pressure in a pipe.

W

Wall Box

A metal or plastic enclosure housing one or more electrical devices.  USA standard 1 gang size is 2” wide x 3.0” high.  The UK standard 1 gang wall box size is 86mm (W) x 86mm (H) (3.425” x 3.425”).  Also known as switch box or back box.
