Illuminance plots of 29278_D

(as computed by ies2tab from that IES photometry file)

spacing 5 plot single luminaire plot
In the left half of the left plot, specific illuminance by a continuous row of luminaires spaced 5 heights is shown (right half is for a single luminaire). The right plot is for a single luminaire, unrotated.

illuminance scale

Values below the scale are illuminance / 1 lx. This is for (unrealistic) “unit” case that luminaires would have lamps producing 1 klm only, would be point-like and just 1 m over the terrain.

# [LUMINAIRE] Classic luminaire, big, suspended luminaire

# [MORE]  reflector segments, pearl diffuser, acryl with frame

# [LAMPCAT] Osram: NAV-T 150W SUPER
# [LAMP] HST 150W
# TILT=NONE
# Bulbs: 1,  17200 lm each
# Number of measured angles:  37 vertical,  37 horizontal ones
# Photometric type: 1,  Units type: 2
# Luminous openig width, length and height:   0.352   0.580   0.000
# Ballast factor: 1,  Input power:  176 W


# Source file: ies/29278_D.ies
# Luminaire flux = 11708 lm,
#                   68.1 % of the bulb flux
# between 75 and 90:  3.9 % of the luminaire flux
#  - this part causes just GLARE in case of road lighting and similar purposes
# 80deg and above:  max  29.0 cd / 1000 lm ,  2.1 % of the luminaire flux
# 90deg and above:  max   4.1 cd / 1000 lm ,  0.9 % of the luminaire flux
# CutOff Type: CIE_CutOff     

#  Increase of Sky Luminance due to light going
#    from the luminaire difectly above horizon, as compared with the
#    luminance produced by the light dispersed from the ground:  25 %
#  Increase of Sky Luminance in Distant Places by light below 15.0 degrees
#    due to light going from the luminaire directly above horizon: 100 %
#  (for the zenith luminance such an angle suits places up to  19 km distance)
#   The increases concern the following situation:
#    Albedo = 0.10
#    Zenith Extinction = 0.30 mag (i.e., direct light remaining  76 %)
#    Indicatrix type =0 (0: acc. to P.Cinzano, 4..6: CIE sky types)
#   (the downward-scattered part of lambertian uplight is 0.1108 then)

# 62.5 deg to <67.5 deg:   max   343 cd / 1000 lm,
# 67.5 deg to < 76  deg:   max   258 cd / 1000 lm,
# maximum spec. lum. intensity   343 cd / 1000 lm

# The following table gives luminous intensities which would be produced
# using a hypothetic bulb giving a luminous flux of 1000 lm (i.e., cd/klm):
