CLD Lighting Design Principles & Techniques 2

Question 1

Which lighting technique uses a light source placed close to and parallel to a wall surface to emphasize texture?

Accepted Answer

Grazing

Answer

Grazing places the fixture very close to the surface at a steep angle, creating shadows that reveal texture and surface relief.

Question 2

What is the primary purpose of a photometric report in lighting design?

Accepted Answer

To predict light distribution, intensity, and quantity in a space

Answer

A photometric report uses manufacturer IES data to model and predict how light will distribute, illuminance levels, and uniformity ratios in a space.

Question 3

In the Munsell color system, what does 'chroma' specifically describe?

Accepted Answer

The saturation or purity of a color

Answer

Chroma in the Munsell system measures the degree of departure from neutral gray, representing color saturation or purity.

Question 4

What is 'sparkle' as an intentional lighting design technique?

Accepted Answer

Small, intense points of high luminance that create visual excitement

Answer

Sparkle is the deliberate use of small, bright pinpoints of light — such as from faceted crystals or narrow-beam LEDs — to add visual energy and interest.

Question 5

A designer specifies a luminaire with a beam angle of 15° for accent lighting. What effect does this produce compared to a 40° beam?

Accepted Answer

A narrower, more concentrated pool with higher center intensity

Answer

A 15° beam angle concentrates light in a smaller, tighter circle with higher center beam candlepower, ideal for highlighting specific objects.
