LC Prep - RAB Course - 2019 - Practice Exam 1 - July 29

An SPD curve will indicate:

• How colors appear or are rendered under a light source

• How warm or cool the light is looking at the light source

• the radiant power emitted by the source at each wavelength

• the amount of power used by the light source

Luminous Flux is:

• The measure of light intensity in a given direction per unit solid angle

• The quantity of the energy of the light in all directions per second.

• Not measured, but perceived.

• Measured in candelas.

The principal radiation emitting device in a fluorescent lamp is called a

• Filament

• Phosphor

• Arc tube

• Cathode

Color temperature refers to:

• The warm or cool appearance of the light source

• The ability of a light source to provide a natural appearance

• The operating temperature of a light source

• The optimum air temperature for a light source

Color Rendering Index refers to

• The ability of a light source to illuminate colors with a natural appearance

• The whiteness of the light emitted by a lamp.

• The ability of a light source to illuminate colors like daylight.

• The degree that a light source will shift the appearance of a set of standard colors.

The shielding angle refers to

• The angle measured from nadir at which the lamp is fully occluded.

• The angle measured from nadir at which the reflection of the lamp in the reflector is fully

  occluded.

• The angle measured from the horizontal at which the lamp is just visible.

• The angle measured from the horizontal at which the reflection of the lamp is just visible.
