Lighting Essentials, Level I Lesson 2
? Assesses the effect of various mild sources at the perceived shade of objects and surfaces -
ANS-Color rendering index (CRI)
? Is the measure of the depth of a mild supply in a selected direction - ANS-Candlepower
? Is the degree of the mild that falls on a surface (illuminance) and is expressed in lumens per
rectangular foot - ANS-Footcandle
? Is the maximum not unusual manner to specific the electricity performance of a light source,
and it's far expressed as a ratio of the quantity of lumens a lamp produces to every watt of
energy it consumes. - ANS-Efficacy
"Visible" light is just a small section of the ? , a huge variety of radiant energy that still includes
X-rays, ultraviolet and infrared energy, microwaves, and radio waves - ANS-electromagnetic
spectrum
A light supply containing balanced quantities of ? Light can provide extraordinary color look
even though this light source is deficient in different shades of the spectrum. - ANS-crimson,
blue, and inexperienced
A(n) ? Is a lamp or fixture this is exceedingly small compared to the location it's miles lighting,
and it has the potential to direct a concentrated beam of mild on a specific floor or item. -
ANS-point source
A(n) ? Indicates the perfect colour output of a given light supply by means of charting the level
of electricity gift at each wavelength across the seen spectrum. - ANS-spectral power
distribution (SPD) curve
Advances in our knowledge of the ? That light and shade have on a extensive variety of human
emotions and sports have made the smart use of those options more and more essential to the
achievement of any lighting installation. - ANS-psychological impact
An inductively coupled electrodeless electronic lighting device makes use of fluorescent light
generation blended with magnetic induction to produce light. - ANS-True
Any form of electromagnetic power, along with light, radiates outward from its source in directly
traces at ? (three hundred,000 kilometers in line with 2d) and dissipates because it gets similarly
from its source. - ANS-the speed of light
