Topicality. Today in lighting installations Ukraine consumes about 25% of generated electricity. Therefore, the energy efficiency of optical systems is an urgent task.

Analysis of recent research and publications. Scientists in the field of electrification of agricultural production (D. Hladyna, N. Kondratyev, V. Lehman et al.) Proved the effectiveness of radiation (different in character) to get additional crop production, and reasonable requirements to regulation of radiation.

The aim - to justify the need for LED light sources for radiation in the greenhouse plants and develop energy efficient system and exposure modes.

Materials and methods. Research has established that economically feasible to irradiate the seedlings, since seedlings during the growing season in the 25 ... 50 days and subjected to exposure once a large number of plants. This product is obtained in 20 ... 30 days earlier; seedlings crop yield increases by 20 ... 25%.

Results and discussion. Found that the light intensity significantly affect the rate of photosynthesis. At low light intensity dominated by the processes of respiration of plants.

When the light intensity increases linearly photosynthesis. Intense light can increase the yield, to get large fruit quality, significantly reduce terms of growth.

For the cultivation of green fodder powerful light is harmful, as growth slows leaf area, leaf quality is reduced, they turn yellow and become rigid.

The researchers found that plants in different periods of growth need different levels of light intensity and spectral composition of radiation, according to the terms of their ecological niche. The proper development of plants is important that they receive the light, well-balanced in the spectrum corresponding to their natural

Conclusions and Prospects. Analyzing the results it can be stated that the system of LED irradiation gives better results compared to sodium exposure to optical radiation sources onion 30 ... 45% for salad - 20 ... 35%.

The feature of LED irradiation is that the LED lamp has a larger radiating surface and provide uniform distribution photosynthesis flow of energy and create a more close to the maximum efficiency for PAR spectrum of radiation.
