What is a Lighting Kelvin Chart?
A Lighting Kelvin Chart is a tool used by lighting designers to choose the color temperature of light they want to create for a particular space. This chart measures the color of light in Kelvin (K) and ranges from warm colors (yellows and reds) to cool colors (blues and greens).
Understanding the Kelvin Scale
The Kelvin scale was named after Lord Kelvin, a physicist from the 19th century. The Kelvin scale starts at absolute zero, where all molecular motion stops. From there, as the temperature rises, it creates different colors of light. This is because at higher temperatures, molecules move faster, and this affects the color of the light they emit.
On the Kelvin scale, lower temperatures create warmer colors, such as yellows and reds. As the temperature increases, the color shifts towards cooler blues and greens. For example, a candle flame is around 1500K, creating a warm orange glow, while a typical LED bulb is around 4500K, creating a cooler white color.
Practical Applications of the Lighting Kelvin Chart
When designing lighting for a particular space, the Kelvin chart can be a useful tool to choose the right color temperature. For example, in a living room or bedroom, a warmer light around 2700K may be more relaxing and comfortable, imitating the color temperature of an evening sunset. In contrast, a cooler light around 5000K may be better suited for a work or office environment, imitating the color temperature of natural daylight, which can help boost energy and concentration.
The Kelvin chart can also be useful when designing the lighting for retail spaces, art galleries, and museums, where selecting the appropriate color temperature is crucial for showcasing products or artwork. Using the Kelvin chart, designers can create lighting setups that enhance the colors in the products or artwork and create a desired atmosphere.
Conclusion
Lighting is a crucial part of any space, and the Kelvin chart is an important tool for lighting designers to select the color temperature that best suits the environment. From warm colors that create a relaxing atmosphere to cooler colors that promote concentration and productivity, the Kelvin chart offers a range of options to choose from. By understanding the Kelvin scale and practical applications of the Kelvin chart, designers can create lighting designs that enhance the space and achieve the desired effect.
