LED

Light-Emitting Diode: A semiconductor diode that emits light when conducting current and isused in electronic equipment and general lighting..


CRI

Colour Rendering Index: A quantitate measure of the ability of a light source to reproduce thecolors of various objects faithfully in comparison with an ideal or natural light source.

3000K = Warm white; 4000K = Natural white; 6500K=Cool white


MacAdam Ellipse

- The technique was developed by MacAdam in 1943 to determine boundariesaround target colour points on the CIE chromaticity diagram whereby the source can deviate beforethe observer can perceive a difference in target colour. MacAdam ellipses were evolved to describe the"steps", which define standard deviations from the target colour point


Lumen

- Unit of luminous flux used to describe a quantity of light emitted by a source or received bysurface.


Lux

- The unit of illuminance, equal to one lumen per square meter (lm/m²).


Candela (cd)

- The base unit of luminous intensity


Luminous Efficacy (lm/W)

- Indicates how efficiently a lamp converts electrical energy to light.


Polar Curve

- The graphic representation of the luminous intensity in different directions.


Beam Angle

- The light distribution angle designates the angle of at which the lighting elementilluminates.


- Degrees of protection provided by enclosures for electrical equipment againstexternal mechanical impacts in accordance with IEC
- Degrees of protection provided by enclosures for electrical equipment againstexternal mechanical impacts in accordance with IEC 

- The IP system is an internationally recognized method to indicate the degree ofprotection against the ingress of dust, solid objects and moisture into an enclosure.The letters "IP" are followed by two numerals.


Impact Protection (IK)

- Degrees of protection provided by enclosures for electrical equipment againstexternal mechanical impacts in accordance with IEC 62262:2002 and IEC 60068-2-75:1997.


Class I

- The unit processes a functional insulation with earth terminal ad earth boding link. The plug ofthese element is foreseen with an earth pin to which all metal parts are connected.


Class II

- The units are foreseen with enhanced insulation preventing access to metal parts. The plugs ofclass II elements do not have an earth pin.


RoHS Directive 2006/95/EC

- The RoHS European Directive (Restriction of the use of certainHazardous Substance in electrical and electronic equipment) restricts the use of certain hazardoussubstances in electrical and electronic equipment: lead, mercury, cadmium, hexavalent chromium,polybromobiphenyls (PBB), polybromodiphenylethers (PBDE).


Operating life (of a lamp)

- The operating life of a LED indicates the duration after which it starts to emita luminous flux lower than 70% of its initial flux. Each operating life expressed on the technical datasheet corresponds to operate at 25°C.


Watt (W)

- Unit of electrical power. The power consumed over a given period represents the energyused.


Analogue Dimming

- A dimming system employing analogue input signals initiating and defining thedimming level that an LED driver or control gear will react to. Typical protocols include 1-10V, 0-10V, andtrailing edge dimming (Triac dimming). Such systems benefit from simplicity but lack the flexibility ofcustomization.


Digital Dimming

- A dimming protocol employing digital input signals initiating and defining thedimming level that an LED driver or control gear will respond to. Typical protocols include push dim,DALI, DSI and DMX.


DMX

- DMX is a standard for digital communication networks that is commonly used to control stagelighting and effects. However, more recently the protocol has gained more interest in the commercialand architectural lighting space.
