Lighting Design-DES 308 Instructor: Julie Peterson Due: Friday, September 9, 2016 Overview NOTES with Julie FUNDAMENTALS OF LIGHTING by SUSAN WINCHIP Light is a form of energy that is part of the electromagnetic spectrum that is visible to the human eye, it is measured in lumens (lm) Importance of quality lighting -Allows for people using that light to function comfortable in an interior space. -People tend to feel safer in well lit areas -Gives an opportunity to appreciate and admire the visual aesthetic that lights have Key characteristics of light and some of the effects light has on the human response Natural Light– Direct light (Sun / Moon) or indirect natural light Layered Lighting– includes natural indirect and direct light mixed with an electrical light source. This can be used for general task, accent and decorative lighting techniques. Lighting can give humans an Emotive response, it can cause you to feel excited, mysterious, magical or even terrified and many more. Basic parts of the eye and vision process • Accommodation: the lens adjusts the perception of light for near and far vision and the cornea focuses light on the retina of the eye by refraction • Rods and cones are detector cells located at the back of the retina • Adaptation:the eye adjusts itself to the amount of brightness entering the pupil -Winchip, Chapter 1 Slideshow, Vision and Lighting –Slide 12 Visual acuity – The ability of the eye to see detail and color General, task, accent, and decorative lighting techniques General Lighting (ambient lighting– less then 30ft candles, softer appearance) - uniform lighting that allows you to see the entire shape and size of a space, it also creates a mood or a character of a space. Daylight is a source of general lighting. Foot candle is a measurement – general lighting tends to 30 to 50 foot candles. Can lights, ceiling lights, fluorescents, windows, sky lights Main light source of a space Task Lighting- Light that is used for specific activities, it tends to beadjustable/flexible and can sometimes have dimmers to customize use for each user. Potential glares, shadows and a possibility of an uncomfortable amounts of bright light.If right handed light should be placed on the left to avoid casting shadows when working on your task. Can create drama within a space. Rule of thumb, idealy task lighting should be 3 times the amount of general light. Greater than 50ft candles usually 150 and up. Typically lighting a horizontalspace. Portable fixtures, pendants, recessed, track and structural lighting Table/desk lamp, surgical or dentist lights, Stove light, Reading light, sewing machine Accent Lighting – (Focal lighting) typically emphasizes artwork, water, fabrics, architectural details, textures, forms and plants. 30 Degree angle of these lights is recommended. This is to distinguish an accent item from its surrounding area. This type of lighting can create dramatic light and shadows which are often found in paintings. Shadows can create unique focal points of a surface or object. Interior and exterior use. Creates a visual hierarchy 5-1 minimum, 10-1 is a lot of drama, and 20-1 extreme and should not go above. Usually forvertical and diagonal planes. Creates the most drama and mystery. Grazing- Reveals texture and form of an object Back lighting – creates a pattern of silhouettes Spotlights, chandeliers,track lighting – (attached directly to ceiling plane)Rail lighting – (dropped lower and suspended below ceiling) Decorative lighting– Focal point of a space/ Ornamental light sources that illuminates an area but are also viewed as artistic pieces Fixtures that are used for general, task, accent, and decorative lighting General lighting- Daylight Task lighting fixtures– Portable, pendants, recessed, track, and structural lighting Accent lighting fixtures- Uplights, recessed spots, spotlight, projectors Decorative lighting fixtures– Chandeliers, Tiffany glass shades, neon tubes, lasers, etc. KEY TO QUALITY LIGHTING - Layered lighting • General • Task • Accent - Utilize natural daylight and also supplement with electrical sources - Providing Transitional Lighting • Hallways tend to be dimmer than rooms • Vestibule • Stairways • Entryways - Flexible lighting • Switch • Occupancy sensors • Dimmers • Timer • Photo Sensors – senses the daylight coming in and dim or brighten depending on time of day and amount of natural light coming in - Energy efficient fixtures and sources • Dimmer • Photo Sensors - Knowing occupants demographic– age, interests - Knowing the function of the space • Tasks that are going to happen in the space - Fixture placement • Create a space without glares - Considering architectural detail already in existence. • Within entire building or in a smaller space • Taking ques from what you already see in the space
