Control of lighting and other installations
Rynek Elektryczny, No. 2/2019, page 30, 28.02.2019
Only a few decades ago, the control of electric home furnishings was limited to switching on and dimming individual lamps. And group control (usually via a normalized analog signal 0-10V) was used, almost exclusively, in special facilities, eg in theaters. Progressive electronization has rapidly expanded the control ranges. Wireless pilots and various control systems have appeared. In addition to light bulbs and fluorescent lamps, new sources of light appeared like halogens, and later LED light sources.
