A
A Formula symbol for a surface in the geometry
B
Background area The background area borders the direct ambient area according to DIN EN 12464-1 and
reaches up to the borders of the room. In larger rooms, the background area is at least 3
m wide. It is located horizontally at floor level.
C
CCT (Engl. correlated colour temperature)
Body temperature of a thermal radiator which serves to describe its light colour. Unit:
Kelvin [K]. The lesser the numerical value the redder; the greater the numerical value the
bluer the light colour. The colour temperature of gas-discharge lamps and semi-
conductors are termed "correlated colour temperature" in contrast to the colour
temperature of thermal radiators.
Allocation of the light colours to the colour temperature ranges acc. to EN 12464-1:
Light colour - colour temperature [K]
warm white (ww) < 3,300 K
neutral white (nw) ≥ 3,300 – 5,300 K
daylight white (dw) > 5.300 K
Clearance height The designation for the distance between upper edge of the floor and bottom edge of
the ceiling (in the completely furnished status of room).
CRI (Engl. colour rendering index)
Designation for the colour rendering index of a luminaire or a lamp acc. to DIN 6169:
1976 or CIE 13.3: 1995.
The general colour rendering index Ra (or CRI) is a dimensionless figure that describes
the quality of a white light source in regards to its similarity with the remission spectra of
defined 8 test colours (see DIN 6169 or CIE 1974) to a reference light source.
D
Daylight factor Ratio of the illuminance achieved solely by daylight incidence at a point in the inside to
the horizontal illuminance in the outer area under an unobstructed sky.
Formula symbol: D (Engl. daylight factor)
Unit: %

Daylight quotient effective area A calculation surface within which the daylight quotient is calculated.
E
Eta (η) (light output ratio)
The light output ratio describes what percentage of the luminous flux of a free radiating
lamp (or LED module) is emitted by the luminaire when installed.
Unit: %
G
g1 Often also Uo (Engl. overall uniformity)
Designates the overall uniformity of the illuminance on a surface. It is the quotient from
Emin to Ē and is required, for instance, in standards for illumination of workstations.
g2 Actually it designates the "non-uniformity" of the illuminance on a surface. It is the
quotient of Emin to Emax and is generally only relevant for certifying the emergency
lighting acc. to EN 1838.
I
Illuminance Describes the ratio of the luminous flux that strikes a certain surface to the size of this
surface (lm/m² = lx). The illuminance is not tied to an object surface. It can be determined
anywhere in space (inside or outside). The illuminance is not a product feature because it
is a recipient value. Luxometers are used for measuring.
Unit: Lux
Abbreviation: lx
Formula symbol: E
Illuminance, adaptive For the determining of the middle adaptive illuminance on a surface, this is rastered
"adaptively". In the area of large illuminance differences within the surface, the raster is
subdivided finer; within lesser differences, a rougher classification is made.
Illuminance, horizontal Illuminance that is calculated or measured on a horizontal (level) surface (this can be for
example a table top or the floor). The horizontal illuminance is usually identified by the
formula letter Eh.
Illuminance, perpendicular Illuminance that is calculated or measured plumb-vertical to a surface. This needs to be
taken into account for tilted surfaces. If the surface is horizontal or vertical, then there is
no difference between the perpendicular and the horizontal or vertical illuminance.

Illuminance, vertical Illuminance that is calculated or measured on a vertical surface (this can be for example
the front of some shelves). The vertical illuminance is usually identified by the formula
letter Ev.

LENI (Engl. lighting energy numeric indicator)
Lighting energy numeric indicator acc. to EN 15193
Unit: kWh/m² year
LLMF (Engl. lamp lumen maintenance factor)/acc. to CIE 97: 2005
Lamp flux maintenance factor that takes the luminous flux reduction into account of a
luminaire or an LED module in the course of the operating time. The lamp flux
maintenance factor is specified as a decimal digit and can have a maximum value of 1
(no luminous flux reduction existing).
LMF (Engl. luminaire maintenance factor)/acc. to CIE 97: 2005
Luminaire maintenance factor that takes the soiling into account of the luminaire in the
course of the operating time. The luminaire maintenance factor is specified as a decimal
digit and can have a maximum value of 1 (no soiling existing).
LSF (Engl. lamp survival factor)/acc. to CIE 97: 2005
Lamp survival factor that takes the total failure into account of a luminaire in the course
of the operating time. The lamp survival factor is specified as a decimal digit and can
have a maximum value of 1 (no failures existing within the time concerned or prompt
replacement after the failure).
Luminance Dimension for the "brightness impression" that the human eye has of a surface. The
surface itself can emit light thereby or light striking it can be reflected (emitter value). It is
the only photometric value that the human eye can perceive.
Unit: Candela per square metre
Abbreviation: cd/m²
Formula symbol: L
Luminous efficacy Ratio of the emitted luminous flux Φ [lm] to the absorbed electrical power P [W] Unit:
lm/W.
This ratio can be formed for the lamp or LED module (lamp or module light output), the
lamp or module with control gear (system light output) and the complete luminaire
(luminaire light output).
84. DINH ANH
Glossary

Luminous flux Dimension for the total light output that is emitted from one light source in all directions.
It is thus an "emitter value" that specifies the entire emitting output. The luminous flux of
a light source can only be determined in a laboratory. A difference is made between the
lamp or LED module luminous flux and the luminaire luminous flux.
Unit: Lumen
Abbreviation: lm
Formula symbol: Φ
Luminous intensity Describes the intensity of the light in a certain direction (emitter value). The luminous
intensity is a matter of the luminous flux Φ that is emitted in a certain spherical angle Ω.
The radiation characteristics of a light source are presented graphically in a light
distribution curve (LDC). The luminous intensity is an SI base unit.
Unit: Candela
Abbreviation: cd
Formula symbol: I
M
Maintenance factor See MF
MF (Engl. maintenance factor)/acc. to CIE 97: 2005
Maintenance factor as decimal number between 0 and 1 that describes the ratio of the
new value of a photometric planning parameter (e.g. of the illuminance) to a
maintenance value after a certain time. The maintenance factor takes into account the
soiling of luminaires and rooms as well as the luminous flux reduction and the failure of
light sources.
The maintenance factor is taken into account either overall or determined in detail acc.
to CIE 97: 2005 by the formula RMF x LMF x LLMF x LSF.

back. The reflection factor is defined by the colour of the surface.

surfaces in the course of the operating time. The room maintenance factor is specified as
a decimal digit and can have a maximum value of 1 (no soiling existing).
S
Surrounding area The ambient area directly borders the area of the visual task and should be planned with
a width of at least 0.5 m according to DIN EN 12464-1. It is at the same height as the
area of the visual task.
U
UGR (max) (unified glare rating)
Measure for the psychological glare effect in interiors.
In addition to luminaire luminance, the UGR value also depends on the position of the
observer, the viewing direction and the ambient luminance. Among other things, EN
12464-1 specifies maximum permissible UGR values for various indoor workplaces.
UGR observer Calculation point in the room, for the DIALux the UGR value is determined. The location
and height of the calculation point should correspond to the typical observer position
(position and eye level of the user).
V
Visual task area The area that is needed for carrying out the visual task in accordance with DIN EN 12464-
1. The height corresponds with the height at which the visual task is executed.
W
Wall zone Circumferential area between working plane and walls which is not taken into account
for the calculation.
Workplane Virtual measuring or calculation surface at the height of the visual task that generally
follows the room geometry. The working plane may also feature a wall zone.
