To start, let's go under the hood to see what's inside a Chromacore-based fixture.
The wizardry behind Chromacore starts with the light source, consisting of clusters of LEDs, which are then arranged into channels of control. For example, a channel might contain a group of LEDs of one color, such as red. A second channel might be made of green LEDs. A third of blue LEDs.
A microprocessor is added to provide the "brains" and the "brawn" responsible for controlling channels.
The "brawn" is the method used to control the apparent intensity of the light output by rapidly switching the channels of LEDs on and off thousands of times per second. To the human eye, the LED output is steady and smooth. This digital manipulation of the LED output is called Pulse Width Modulation.
Varying the output of each of the channels of LEDs creates a vast array of lighting effects. Using this example, let's take the three channels of red, green, and blue LEDs. Changing the output of each of these primary colors produces millions of different colors. This additive color mixing is the strength behind the spectacular colors and effects produced by all Chromacore-based lighting fixtures.
The "brains" provide the ability to assign the fixture a unique network address or to access and display a range of pre-programmed lighting effects. As you can see, Chromacore incorporates a high level of intelligence directly at the illumination source. The benefits? Happy LEDs that are digitally controlled at optimum current levels.
So, now that you understand the circuitry magic, let's move on to the digital lighting fixture.
