Knowledge of Lighting
(1) Lighting Basic Term
- Display color rate: in principle, the man-made ray and nature ray
both is the same , use naked eye can adapt to distinguith case color
lamp-house , for the object color show itself grade become display color
rate , usually we call it is "display color rate".
- Color temperature : then the lamp-house shoot the light color ,and
"back body " temperature higher and higher ,in the action
spectrum analysis is be more and more ,and that red anlysis will be
less and less, for example: the incandescent lampe's light color is
warm-white ,the color temperature denotation is 2700K,and that light
color fluorescence lampe's color temperature denotation measure is 6000K.
- Ligt color:in fact the light color is the color temperature, large
circumstance will be part three style: warm white<3300K,mid-color3300K-5300K,daylight
color>5300K,because the action spectrum in the ray have different
pare be compose , so that even if the light color is the same ,maybe
the light display color is dissmilar.
(2) The display color rate & display color denotation
The lamp-house for the object's display corol ability be intitule is
display corol rate, is pass the same color temperature ref errence or
benchmark lamp-house(fluorescence lampe of draw light )below the object
facies to be compare.the light shoot the action spectrum content decide
the light color of the lamp-house ,but also the light color can have more
and less indeed only pair unit color's light-wave to be compose,for the
action spectrum to compse rather extensive lamp-house relatively by likely
to offer better display color quality.
Display color part two kinds.
- Fealty display color: can right exhibition object originaly color
need to use the display color rate high lamp-house,that numerical value
appropinquity 100 ,display color rate is the best.
-
Effect display color :must brightly emphasize speciffically
color,exhibition beatiful life can using add color's means to strenghen
display color effect .adopt the low color temperature lamp-house shooting
,can be let the red brightly and brightly ;abopt mid-color temperature
lamp-house shoting ,can be the blue have refrigerant feeling;abopt
high color temperature lamp-house shooting ,let the object have cool
feeling.
(3) Display color exponential & display color rate ralation
Then in the lamp-house action spectrum have a little or absence object
below benchmark lamp-house shooting main-wave . will be let color bring
obvious color shift .color difference grade more bigger,lamp-house vs
the color display color rate be more bad , deduce color exponential coefficient
still is at present define lamp-house display color rate appraise usual
means.
Incandescent lamp's color temperature exponential define is 100, treat
perfect benchmark lamp-house. The system as 8 kinds color grade midding
normative color model to check ,below the comparative test lamp-house
and below the same color temperature's benchmark lamp-house. The 8colors
devaitoin grade, as the measure the lamp-house' display color enponential,
adopt average deviation rate 20-100, as the 100 be the highest, average
color more bigger, rate value more lower, under the 20 lamp-house usually
unsuitable exumenical using.
