Everyone is buzzing about the benefit of LED lighting. From clear illumination indoors and outside to saving energy, there are lots of advantages for people with LED lights. But the basic terminology can get confusing. Consider some of the LED lighting lingo everyone should know before they go shopping for new lights.
Light
As simple as it sounds, everyone should understand the scientific concept of light. To be visible to the human eye, light must have radiation between 38onm and 78onm. Visible light is referred to as spectrum which includes the color red, blue, yellow, greens, and the hues in between. The fewer colors in the spectrum, the weaker the color reproduction of the light source. If there are more colors in the spectrum, then more are visible.
Glare
People know glare when they see it and it makes it difficult to see in certain places. Luminaries with too high luminance will cause direct glare. Indirect glare is caused by reflections, such as mirrors or shiny surfaces. Glare makes it impossible to see and can lead to accidents.
Color Temperature
Formally referred to as correlated color temperature (CCT), this refers to how a light source radiates light in a particular color. Some lights are warmer than others. CCT is measured in Kelvin (K). A luminance camera is used to measure the color temperature of lighting. Common color temperatures for products include warm white, natural white, cool white, and day white.
Color Rendering Index
The color rendering index (CRI) describe the colors of the light source to determine its spectrum and brightness. For example, the best CRI rate of 100 comes from sunlight because it represents all colors and has a wide spectrum. LED lighting ranges from 70 to 95, which is higher than fluorescent tubes. As a result, LED lighting can be used for a multitude of purposes and settings.
Spectrum
Spectrum is the visible range of lighting, based on the number of colors represented in the spectrum and the distribution of radiation. A luminance camera is also used to measure the spectrum.
Radiation Angle
The angle of light and how it emits light from the source is referred to as the radiation angle. The smaller the angle, the smaller the lighted surface. However, the list is more focused. A Goniometer is used to measure the radiation angle of luminaries.
Light-Emitting Diode
A light-emitting diode (LED) is a semiconductor device emitting visible light when an electric current passes through it. The output from an LED ranges from red to blue-violet. LEDs consist of two processed materials, P-type semiconductors and N-type semiconductors. The two join to form a P-N junction. Benefits of LED lighting include a lower power requirement, long life, and high efficiency.
LED lighting is used for a variety of purposes, ranging from outdoor lights to parking lot lighting. The diversity and affordability of LED lights are making them a top choice for businesses and homeowners. People are saving energy and changing light bulbs less often with LED lights. Work with an LED lighting professional to find the ideal solutions for your home or workplace.
