Colour-Tuneable Light Sources: A Demand of Modern Society |
| With the invention of efficient blue light-emitting diodes by Shuji Nakamura, a bright energy-saving white light source has become the base for a widely used artificial light source. Just in a decade, the LED market has grown from just a monochrome light source to colour tuneable light source. A tuneable light source is a technology in which the user has the ability to control a light source’s colour and intensity. Mixing and producing a wide variety of spectrum with RGB LEDs are called colour-tuneable lighting. Tuneable lighting can also be referred to as custom lighting where the lights can be made to adjust according to the environment or the user preferences. Moreover, colour-tuneable light affords the ability to attune lighting to individual preferences or specific application needs. In the case of white tuneable LEDs, the colour of white is quantified by referring to its colour temperature. Tuneable lights are becoming the first choice of users (homeowners and commercial building owners) due to their unblemished behaviour. |

| Tuneable light source combines multiple light sources, which controls the multiple light sources individually to shift or tune the required colour. This has led to a marvel of both engineering and addressing the issue of human psychological perception about natural light. Tuneable light source has changed the way human perceive artificial light source that no other light sources had shown since the first incandescent light bulbs appeared on the market in the 19th century.
