The main point: Research light emiting diodes RGB (red, green, blue) matrix with controllable spectrum of light. I have made that matrix, and researching energetic, light and technicality datum. To use that light sources for lightening of emergency. To review other liht sources. Stepping stone and results: There are made review of most popular light sources, quality and limitation. There are overlook of semiconductors light sources and the range where they are using now. Experiments are made with our LED illuminator with minimal number of LED. There are noticed, that LED can take energy from light and that we use to make manage of others light sources. Illuminator are adapted to work in emergency lightening. The result can be use: The result can be use for development LED in Lithuania, to know people more about semiconductor light sources ant to use it ours home.
