Popularity in recent years, the solid state LED lamps and lanterns, the author here try to parse the LED color technical complexity and its control method.
About the addition of mixed color LED lamps and lanterns USES multiple
light sources to obtain all kinds of colored light and strength.
For the performing arts industry of lamps and lanterns, additive color mixture is a cliche.
Over the years, practitioners with the lamps and lanterns of color filter is used to cast the awning in the same area, the control was not easy.
The author USES the first intelligent lamps and lanterns is a use 3 spotlights MR16 illuminant, each with a red, green and blue color filter.
Early, this kind of lamps and lanterns only three DMX512 control channel, no independent strength control channel.
So it is difficult to keep in the process of dimming color remains the same.
Usually, the amount of programmers will also set up a 'destroy the light in color', in order to easily put out the lamps and lanterns.
Of course, there's a better way, here no longer list.
Color control and define if the user need not pure DMX values to control intelligent lamps and lanterns, and in some abstract way of control, you can use a virtual intensity values.
Rules even if manufacturer of lamps and lanterns USES three DMX channel, the abstract control mode can also be assigned four controller to control: strength and three color parameters.
Here the author wrote '' three color parameters, rather than the red, green and blue, because the RGB is just a way of describing colors.
Another way of describing is hue, saturation and brightness
HSL（
Have called it intensity or brightness, rather than the brightness)
。
Another kind of description is the hue, saturation and brightness (
Lightness)
Is also often referred to as (
Brightness)
It is similar to the brightness.
However, an HSL and HSV definition of saturation difference is very big.
For the sake of simplicity, the author in this paper define the color for the color, the degree of saturation is defined as the amount of color.
If 'L' is set to 1000, it is white, 00 is black, so, 508 L is saturation for l003 pure color.
For the 'V', O6 was black, l002 is pure color, saturation value must now make up the difference.
Another effective way of description is CMY, they are the three primary colors, use subtraction mixed color.
If a white light at first, then, can use two color filter to get red, magenta, and yellow;
They remove white light the green and blue components respectively.
In general, do not use subtraction mixed color LED color lamps and lanterns, but it is still an effective way to describe color.
In theory, when control of LED, should be able to adjust the intensity and RGB and CMY.
One of the an HSL or HSV (
There is some difference between them)
