PERCEPTION OF METRICS

THE INTERSECTION OF COLOR CHARACTERISTICS AND QUALITIES GUIDED BY PREFERENCE

INTENT: STUDY THE RELATIONSHIP BETWEEN COLOR CHARACTERISTIC S OF TUNABLE LED SOURCES AND SUBJECTIVE IMPRES SIONS AND PREFERENCES

IN ORDER TO UNDERSTAND THE IMPLICATIONS AND PERCEPTUAL DIFFERENCES OF COLOR METRIC S AS SOCIATED WITH AN LED SOURCE .

THIS INFORMATION CAN BECOME A NEW TOOL OR METHOD OF COMMUNICATION BOTH WITHIN THE LIGHTING COMMUNITY AND FOR END-USERS.

THESIS STATEMENT

“LIGHT CAN BE ACCURATELY MEASURED, BUT NO AMOUNT OF MEASUREMENTS CAN TRANSMIT THE ESSENCE OF A LIGHT PHENOMENON AND THEREFORE CAPTURE ITS PRESENCE, AS THIS IS CAPTURED IN THE HUMAN PERCEPTION AND APPREHENSION.”

-Rudolf Arnheim, Visual Thinking, 1968

“LIGHT CAN BE ACCURATELY MEASURED, BUT NO AMOUNT OF MEASUREMENTS CAN TRANSMIT THE ESSENCE OF A LIGHT PHENOMENON AND THEREFORE CAPTURE ITS PRESENCE, AS THIS IS CAPTURED IN THE HUMAN PERCEPTION AND APPREHENSION.”

LED TECHNOLOGY HAS CHANGED THE WAY WE DESIGN WITH COLOR METRICS, MEASUREMENTS & STANDARDS MUST EVOLVE WITH THE TECHNOLOGY

TITLE

• Color has the closest correspondence to pleasant/unpleasant, like/dislike, satisfying/frustrating, relaxing/tense and beautiful/ugly.

• Red chroma shift continues to be a good indicator of preference.

• Sources with lower CRI can be preferred. High levels of GAI do not ensure high ratings of naturalness. Red was the color that most heavily influenced decisions.

• Subjects preferred cool white (4000°k) in a malaysian school and felt it was the most comfortable for an extended period of time. No significant differences in computer/paper based tasks.

• 4500°k was rated most pleasant, 3500°k was rated the most colorful and brightest. 6500°K was rated least pleasant and colorful and 2800°k was rated the least bright.

• 2500°k was consistently rated low with 4500°k was consistently rated high. Preference is associated with saturation.

EXPERIMENTAL RESEARCH

EXPERIMENT 1

GOALS: Determine if any metrics or color rendering qualities in particular are preferred.

HYPOTHESIS: “High� performance metrics/sources will not necessarily be preferred.

• For this portion of the experiment, I would like you to imagine you are having a relaxed, causal evening with friends or family.

• For this portion of the experiment, I would like you to imagine you are concentrating on completing a task.

• For this portion of the experiment, I would like you to look in the mirror, as if this were the place you evaluate your appearance.

• Application could be used online or in stores • Filtering service select “clear” + “moderately colorful” to narrow down the endless choices.

• Assist not only consumers, but interior designers, electrical engineers, specifiers, manufacturers and lighting designers.

This lamp setting is appropriate to use at bedtime or for relaxing. Your environment will have muted colors and feel very warm and rosy. This light is most likely too dull for daily use, but should be considered as an accent light in the evening.
