Light consists of seven colors, namely red, orange, yellow, green, blue, indigo and violet. The seven colors can be fractionated using a prism. Scattered light is known as a spectrum of colors. Humans can see the color of an object if the object is exposed to light. Red color appears because it absorbs the entire color spectrum, except the red color spectrum. The object is black because it absorbs the whole spectrum of colors, and white if it reflects the entire spectrum of light that hit it.
As a form of energy, speed of light is moving at 299 792 458 meters per second. Light also has a wavelength that is different. These wavelengths are interpreted by the human brain as color. Red has the longest wavelength, while the violet the shortest. To measure the presence of this light, used a special tool. Units of brightness (temperature), illumination (lux) illumination flux (lumens), luminosity intensity (candlepower) are often used as a benchmark to measure light quantities.
Lighting system is an important element in the home. Structuring a slick, make each room appear more beautiful and more effective functioning. The light used to illuminate the object in order to create an atmosphere that is more beautiful and exotic. Though simple, design a lighting system may be quite complex. Many things to consider, among other functions of space, character building, character owner, occupant activities, also wanted to create an atmosphere.
In line with developments in technology and design, artificial lighting can be pushed around at will.
Using dimmers, light intensity can be adjusted at will to obtain the appropriate atmosphere in the mood. This is somewhat different from the sun. Intensity and “color” natural light source is very depending on location and time. Any decisions that you specify, will be very influential on all aspects of the space. Light and shadow can create a decorative element or furniture is more beautiful. With a light, you can create a comfortable space for their activities. Light can also create space so calm, so perfect for relaxation. Conversely, a bad arrangement will make the room uncomfortable for both activities. In general, there are three types of lighting, i.e., general lighting, task lighting, and accent lighting.
General Lighting is the main lighting in the room marked by the placement of this type at some point lights are used to illuminate the room evenly. For example by placing a large watt of lights on the center ceiling or placing multiple light sources are switched on simultaneously. To make it happen, you can simply place a ceiling lamp in the middle area of the house. Another way is to put some lights. For example by placing a spotlight on some down lights and ceiling.
Task Lighting As the name implies this type of lighting works for shed light on a specific object. For example, at the kitchen table area, reading areas or areas of ironing and folding clothes. Unlike the general lighting, task lighting; shine light onto a specific area. In the kitchen, the type of lighting is usually installed under kitchen cabinets. Its function is to illuminate the kitchen table and help the food processing. In the reading room, task lighting used to illuminate the reading area.
Task lighting is also used to illuminate the artwork on the wall paintings or sculptures in the display cases. As illumination light shined in limited areas, task lighting can be created through the use of a spotlight, standing lamp or desk lamp.
Accent Lighting is a type of lighting that evokes the atmosphere dramatically. Its function is to create a mood in the room. This type of lighting can be obtained by placing a wall lamps, track lighting, lamps, or houses that have a wide beam shape and direction.
To create a mood, accent lighting is illuminated paintings or works of art. This type of lighting was also obtained by placing a lamp on the floor or bottom wall. In order to view the light that comes out is more flexible, dimmers added to adjust the brightness of light
