AR INTRS 312: Lighting Systems Quiz

Study Notes

Lighting significantly enhances the appreciation of architectural beauty, influencing perceptions and emotions in a space.
Whether natural or artificial, lighting can accentuate textures, colors, and forms.
Effective architectural lighting requires a balance among aesthetic, function, and efficiency.

Aesthetic: Focuses on creating emotional responses; especially crucial in retail to attract consumers.
Function: Ensures adequate lighting for activities and usability across different spaces.

Local Lighting: Provides focused light at specific points, creating pools of illumination with shadows.
General Lighting: Aims for uniform, diffused light across an entire area to minimize glare and harsh shadows.
Combined Local and General Lighting: Offers general illumination along with localized sources for specific tasks.

Intensity of Illumination: Varies based on task requirements:
- Casual work needs 10-30 fc.
- Moderate work requires 30-50 fc.
- Prolonged tasks need 50-100 fc.
- Precision work calls for 100-150 fc.
- Fine precision tasks require 150-200 fc.
Quality of Light:
- Uniformity: Light intensity variations should not exceed 25% in a space.
- Diffusion: Achieved by illuminating surfaces from multiple angles, minimizing shadows.
- Reflectance: Ratio of light reflected off surfaces to incident light.
- Transmission: Light passage through materials, such as transparent and translucent mediums.

Accent Lighting: Focused illumination to highlight specific spaces or objects.
Down Light: Provides direct lighting, often recessed into ceilings.
High Hat: Refers to recessed incandescent lighting fixtures.
Eye Ball: Recessed units with adjustable light direction.
Dimmer: Device to control light levels by reducing voltage.

Standpipe Systems: Include various classes for use by fire departments and trained occupants.
Fire Department Connections: Enable firefighters to supplement building water supply during emergencies.
Fire Alarm Systems: Essential for occupant safety; includes automatic systems that detect smoke/heat and manual alarms.

Satin Paint: Durable with a semi-gloss; advisable for high-traffic areas like kitchens and bathrooms.
Semi-Gloss Paint: Reflective and visually appealing; used in high-moisture spaces but should be cleaned delicately to minimize wear.
Glossy Paint: High sheen and reflective; easier to clean but can reveal surface imperfections.
Chalkboard Paint: Requires primer for application; becomes hard and scratch-resistant for various surfaces.
