Light consists of seven colors, namely red, orange, yellow, green, blue, indigo and violet. The seven colors can be broken down using a prism. Separate light is known as the color spectrum. Humans can see the color of an object if the object is exposed to light. The red color appears because it absorbs the whole spectrum of colors, except red color spectrum. Objects are 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, light travels at a speed of 299,792,458 meters per second. Light also has a wavelength that is different. Wavelength that the human brain is interpreted as a 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), luminasi intensity (candela) is used as a benchmark to measure the quantity or intensity of light. Lighting is an important element in the house. Structuring a slick, making each room look more beautiful and more effective functioning. Light used to illuminate the object in order to create a more beautiful and exotic. Although simple, designing lighting dilata 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 innovation, artificial light can be pushed around at will. Using a dimmer, the light intensity can be set arbitrarily to obtain a suitable atmosphere mood. This is somewhat different from the sun. Intensity and "color" natural light source is very dependent on the location and time. Any decision that you specify, will be very influential on all aspects of the room. Light and shadow to create a decorative element or a furniture look more beautiful.
