What Is Light?

07-29-2008 01:09 PM CET | Energy & Environment

Press release from: BulbAmerica

The simplest definition of light is “visually perceived radiant energy.” “Visible” light is just a small segment of the electromagnetic spectrum- a broad range of radiant energy which also includes X-ray, ultra violent and infrared energy, micro-waves and radio waves. Any form of electromagnetic energy, including light, radiates outward from its source in straight lines at “the speed of light” (300,000 kilometers per second) and dissipates as it gets further from its source.

As visually perceived radiant energy, light powers the mechanism of sight. It is light, reflected from objects to our eyes, that allows us to see. Of all our senses, sights the most dominant, controlling and defining how people perceive the world. And yet its impossible to prove that any two people see a given object in exactly the same way. In fact it often seems that visual perception-an individual’s response to light-is extremely subjective. This makes it difficult to define and measure specific attributes of light. Furthermore, changes in light can changes in light change people’s perceptions. A dark alley, for example, provokes an entirely different reaction than one that is brightly lit. lighting, therefore, can have a profound effect on people’s emotions and how they respond to the enviorment.

Two Ways to Look at Light
There are two systems of measurement commonly used to describe the color properties of a light source: “color temperature,” which express the color appearance of the light itself and “color rendering index” (CRI), which suggests how an object illuminated by that light appear in relation to it appearance under other common light sources. Both can be extremely valuable in evaluating and specifying light sources, but it is important to understand University: How High Intensity Discharge (HID) Technology Works
The technology in high intensity discharge lighting is in some ways similar to fluorescent technology: an arc is established between two electrodes in a gas-filled tube which causes a metallic vapor to produce radiant energy. In this case, however, a combination of factors shifts the wavelength of much of this energy to within the visible range, so light is produced without any phosphors. In addition, the electrodes are only a
