TOOLS · LIGHT QUALITY LED Spectrum Mixer Mix five example channels, or build your own source combination. Explore colour, tint and colour rendering. Example spectra only — not Lightstec product measurements or calibrated driver settings. How it works Principles of mixing spectra Every LED light is a sum of light sources. A mixer adds the individual spectral power distributions (SPD) of its channels to build one composite spectrum — and from that spectrum the viewer derives colour, tint and rendering. 1 · Linear channel mixing Each channel has … Читать далее

TOOLS Pixel LED Address Planner Plan your pixels, outputs and DMX addresses. THE BASICS How pixel LED address planning works Addressable pixel LEDs (WS2811 / WS2812 / TM1814 style) each carry their own colour data. This planner maps those pixels to universes, outputs and DMX channel addresses. A few concepts make it clear. PIXEL What is a pixel A pixel is the smallest group of LEDs you can control independently. A strip may pack several LEDs into one pixel. Enter independently addressable pixels, not the advertised LED count. … Читать далее
