Where Can The Adjustable White Illumination Apply?

Jan 16, 2018

Due to the development of the lighting industry, it is now possible to "add" the desired color temperature to certain lamps at specific times during the day or night. A major trend towards this goal is the mixing of different color LEDs in the construction plant. For example, a luminaire may consist primarily of a cool led (for example, 4000K). If you add a red led to the array, and the different colors of the LED can be individually controlled, then the color output of the lamp can be changed from "cold white" to "warm white". If the lamp contains an RGB LED matrix, you can achieve a larger gamut (range) of color output.


The second trend is the emergence of more advanced control systems in building lighting. More and more systems now contain standard options that allow users to manually change or even preset the color temperature of individual lamps at one time of the day.

Where is the "adjustable white light" lighting useful? Submarines are a perfect example of application. When submarines dive into the water, they may not see daylight for weeks or months. Changing the level of light, changing the color temperature from warm colors to warm colors, can simulate natural daylight and help regulate the biological clock in the submarine.


Even in the presence of daylight, different levels of illumination and color output can mimic natural conditions similarly. Some studies have shown that this has a positive effect on attention and productivity. Therefore, the office workers can benefit. Another potentially beneficial application is the classroom. In addition to increased attention, studies have shown that the sleep cycles of school-age children (especially adolescents) can be better regulated by using simulations and by strengthening natural light. To achieve these benefits, it is important to use a luminaire that can modify the output and color. Obviously, you must also deploy a control system that allows you to set (or preferably preset) different lighting levels and color temperature.


The adjustable white lighting system can also be used for specific effects. For example, in a classroom, factory or office, changing the level and color of lighting before lunch can mean stopping work (or learning). When you get back to the office after dinner, changes in the level and color of the light can make people "awake" (similar to having a cup of coffee). When you get off work, lowering the light level and increasing the color temperature can indicate that working days or school days are coming to an end.


Another application that can benefit is the retail store. In the day, constantly changing the light output and color, by giving space to increase diversification, can stimulate sales. It can also be used for the reminder feature. For example, you can make some changes in brightness levels and colors that might be better than advertising a sales item.


The restaurant and other reception areas can also use adjustable white lighting to change the surroundings. For example, a restaurant can use brighter and cooler light for breakfast and lunch, and a darker, warmer light for dinner.


Any change in the color of the light (and the level of the light) will have a physiological effect on the human body, as well as the visual environment. If you have any questions about the influence of the adjustable white light illumination, you can consult the lighting professional.
