Controlled lighting booth

ASTM D1729 and ISO3664

Controlled lighting booth for color evaluation and color comparison

Color appears different on surrounding colors, it's necessary for comparison of standard and sample in a designated color environment, use of a controlled lighting booth to simulate different lighting conditions helps to obtain objective color assessment without environmental color influences. The light source including:

Features:

1)        Controlled
lighting booth
with standard light sources of Artificial Daylight D65,
TL84, CWF, F / Incandescent A, UV and U30 which are all identified and regulated by CIE
simulates different light sources to obtain an objective color evaluation, anytime, anywhere.
2)        Metamerism phenomenon
can be detected.
3)         Elapsed time meter for tracking optimal lamp replacement.
4)
Easy to operate by using individual switches for each light source.
5)         No warm-up time or flickering which insures quick and reliable color evaluation.^{Name

Background knowledge
^{•Artificial Daylight D65}

- Corresponds to a mid-day sun, a commonly-used standard illuminant defined by the CIE. It
is part of the D series of illuminants that try to portray standard illumination
conditions at open-air in different parts of the world. Artificial Daylight D65
light sources do not exist actually, only simulators. The quality of a simulator
can be assessed with the CIE Metamerism Index. —CIE
S005/E-1998. ^•^{TL84

-} CIE Fluorescent Illuminants, Light Source (F11), TL84 light
source represents a tri-band fluorescent lamp. —CIE 1931. ^•^{CWF

-} CIE Fluorescent
Illuminants, Light Source (F2), CIE F series light sources represent various
types of fluorescent lighting. CWF(Cool White Fluorescent) light sources found
in office environments^{.

•Incandescent A}

- CIE Incandescent A is intended to represent typical, domestic,
tungsten-filament lighting. Its relative spectral power distribution is that of
a Planckian radiator at a temperature of approximately 2856 K. CIE standard
Incandescent A should be used in all applications of colorimetry involving the
use of incandescent lighting, unless there are specific reasons for using a
different illuminant. It is found in our home. ^•^{UV

-}

UV Ultra Violet Black light to reveal the presence of fluorescent
dyes and bleaches.^{•U30/U35

-}
Neutral-white
fluorescents have a CCT (Correlated color temperature) of 3000K or 3500K.
^•^Metamerism

- when color samples appear to match under one illumination condition but
distinctly change when viewed under a different illumination condition.
