The article deals with the creation of the LED light sources on the principle of RGB mixing. The design of the high-power (up to ~ 3000 lm) dynamically controlled semiconductor light source based on the matrix of multicolor emitting crystals has been developed. This lighting instrument comprises an emitting module with a control processor, power drivers, and a controlling part with appropriate software and radio-communication channel for information exchange with an emitting module. An analysis in every detail was made, and a network configuration was worked out on the basis of the ZigBee technology for various network coordinators. A circuit for blocking-out the power LED drivers was set up for heavy current (1.5 A). The polychromatic LED matrix including a monolithic white crystal was designed. As a whole the product developed is a finished system of dynamic lighting that maintains the optimal light environment for human life.
