The light of these LEDs is mixed in different proportions by adjusting the current ratio between the LED channels. Tunable white systems are equipped with cool white and warm white LEDs. HCL utilizes tunable white technology to modulate the color temperature of white light, within luminous intensity controlled independently. The discovery of the biological influence from light created the concept of human centric lighting which simulates the spectral quality and intensity of natural daylight over the entire day to support the human circadian rhythm and keep natural melatonin production in balance. Dim-to-warm lighting can replicate the familiar glow of incandescent lamps as they are dimmed to a lower intensity, thereby creating a comfortable, intimate ambiance in restaurants, hotels, and high-end residences.
Dimming can also alter the spectral composition of light. Adjustment of luminous intensity can help create an environment with the most sought-after ambiance throughout the day or event. Dimming is frequently used in spaces where flexibility is important and the ability to create different scenes is highly desired. With variable light output, lighting designers can create dynamic layers of light, balance the distribution of light, reinforce design aesthetics, and enhance the comfort and performance of tasks. Customizing light scenesĭimming control plays an important role in the lighting design process. Integration with occupancy sensors, vacancy sensors, photosensors, and/or time clocks allows dimming operation to be automatically triggered. Interfacing with a building management system (BMS) or a home automation system enables programmed adjustment of light output.

Aside from light management through manual adjustment of individual lights and programmed scenes that incorporate multiple luminaires, a tremendous opportunity exists to save energy and reduce operating expenses through the use of automated controls.
Dimming technology is ubiquitously utilized to unlock the power of LED lighting: Increasing energy savingsĭimming can maximize energy efficiency of lighting by offering the right amount of light. LED's superior controllability and its ability accommodate the integration of sensors, processors, and network interface enables functional, flexible, adaptive and intelligent lighting. Today's lighting revolution is spurred on by LED technology. The importance of LED dimming is beyond what most people would ever imagine. And these advanced applications can only be realized through LED dimming. The trend towards the interaction of lighting control with IoT devices calls for a robust dimming solution which can support the most sophisticated lighting scenarios. Today, light source dimming is no longer merely used to maximize energy efficiency and enhance visual perception. The instantaneous response of LEDs to changes in power input lends them perfectly to dimming control. The advent of solid state lighting based on LED technology opens up a host of advanced control opportunities. Dimming refers to operation of adjusting the lumen output or changing the perceived brightness of a light source. No matter which lighting control strategy is used, dimming is, in most cases, an indispensable tool to accomplish that goal. No matter which lighting technology is used, the ability to effectively control the output of a light source is essential.
