Description

ld_update() changes configurable parameters in the light distribution data. The principal light distribution is not altered in the process.

Usage

ld_update(
  ld_list,
  filepath = NA,
  file_name = NA,
  company = NA,
  report_no = NA,
  luminaire_name = NA,
  luminaire_no = NA,
  date_user = NA,
  length = NA,
  width = NA,
  height = NA,
  length_lum = NA,
  width_lum = NA,
  height_lum_C0 = NA,
  height_lum_C90 = NA,
  height_lum_C180 = NA,
  height_lum_C270 = NA,
  lamp_no = NA,
  lamp_type = NA,
  lum_flux = NA,
  cct = NA,
  cri = NA,
  power = NA
)

Arguments

file_name	Name of LDT-file without extension
company	Company identification/databank/version/format identification
report_no	Measurement report number
luminaire_name	Luminaire name
luminaire_no	Luminaire number
date_user	Date/user
length	Length/diameter of luminaire (mm)
width	b - Width of luminaire (mm) (b = 0 for circular luminaire)
height	Height of luminaire (mm)
length_lum	Length/diameter of luminous area (mm)
width_lum	b1 - Width of luminous area (mm) (b1 = 0 for circular luminous area of luminaire)
