(57) Abstract:

The invention is intended to create in the greenhouse required for plants grown culture light conditions. The method includes pre-operational lamps in the greenhouse test them to detect external defects and their characteristics parameters input control, culling lamps with external defects and deviations in the input control, the layout of the remaining lamps in the group for inclusion in the irradiator and use them within a period corresponding to a cycle of vegetation grown in the greenhouse plants. In the validation process gas discharge lamps additionally determine the compliance of their parameters on the spectral composition of the radiation to the nominal values of these parameters for grown in the greenhouse plants, and linking groups in the irradiation system is carried out lamps with the same parameters on spectral composition of radiation. The implementation of the input control eliminates the possibility of operating in the greenhouse lamps with parameters out of limits. The holding current control together with activities reflow lamps in groups prolongs service life, ensure the plants crops on the current stage of vegetation development.

The invention relates to agriculture, namely, the operation of gas discharge lamps in the greenhouse, and can be used in the operation of the irradiated plants used in the breeding climatic structures in which higher requirements to the spectral composition of radiation.

The known method of operation of gas discharge lamps, which is carried out by first measuring the parameters of the lamps upon acceptance, a further operation until the limit of the normalized integral of the light flux and recycling of used (burned) gas discharge lamps with expired lifetime [1].

The disadvantages of this method include the following: when applying it does not take into account changes in the spectral composition of light occurring during operation of gas discharge lamps, and significant maintenance efforts irradiated plants for the individual way to replace burned-out lamps on the ground.

Also known a method of operating a gas discharge lamps in the greenhouse, providing for prior to their use in the greenhouse test lamps to detect external defects and sootle input control, the layout of the remaining lamps in the group for inclusion in the irradiated install and use the latest within a period corresponding to the cycle of vegetation of plants grown in the greenhouse culture [2].

This method also has its disadvantages.

When picking irradiated plants (after making another group of replacing all lamps in one unit can be a lamp with a different running time, and hence with different parameters on the spectral composition of the light flux emitted light, which has a negative effect on the plants.

Even new bulbs have technological dispersion spectral and electrical parameters between them. The joint operation of these lamps leads to disruption of nominal parameters of the rational mode in the greenhouse, which usually leads to the reduction of the technological effect of irradiation plants, increase in energy and material losses.

Increased consumption lamps with this method cannot be compensated for by using lamps with a lower light output for less important objects, because a discharge lamp still removed from the main technologo service life of the lamps.

The aim of the invention is the provision of a minimum deviation of parameters of radiation regime in the greenhouse from the nominal values during the entire period of operation of the irradiation facility, as well as increasing the useful life of the gas discharge lamps.

This goal is achieved by the fact that in the method of operation of gas discharge lamps in the greenhouse, providing for prior to their use in the greenhouse test lamps to detect external defects and their characteristics parameters input control, culling lamps with external defects and deviations in the input control, the layout of the remaining lamps in the group for inclusion in the irradiator and the latest within a period corresponding to the cycle of vegetation of plants grown in the greenhouse culture, according to the invention in the validation process gas discharge lamps in accordance with their characteristics parameters input control additionally determine the compliance of their parameters on the spectral composition of the radiation to the nominal values of these parameters for plants grown in the greenhouse culture, and linking groups in the irradiation system is carried out lamps with the same parameshwar by holding before each cycle of vegetation of plants grown in the greenhouse culture of control, inspection and control of technological parameters of gas discharge lamps according to their conforming to the requirements culling substandard lamps, layout standard lamps in the group for inclusion in the system of the exposure and use the latest within a period corresponding to the cycle of vegetation.

Control lead by alternately scanning all incoming discharge lamps before their operation to detect defects caused by rough factory assembled, or defects detected by external examination by incoming inspection.

Immediately before the loop vegetation set required for plants grown culture character of the energy distribution of the optical flow of the photosynthetically active radiation spectral ranges, and in the process of control of technological parameters of gas discharge lamps further define the nature of the distribution of energy radiated by them of the optical flow on the mentioned spectral ranges, the composition of groups in the system of the irradiation is carried out lamps with the same distribution of the specified parameter, the corresponding desired to plant their crops.

After the end of the vegetation period of plants and replaced after use gazoraspredeleniye their emitted optical flow on spectral ranges for the composition of groups in the system of the irradiation with the same pattern of distribution parameter and use in a subsequent cycle of vegetation. All discharge lamps rejected during the passage of the current control and the implementation of the input acceptance control, is disposed.

The proposed method is implemented as follows.

At the stage of acceptance checks coming through the bodies supply of lamps in order to identify instances of defective assemblies, transportation, etc. and rejection of defective lamps.

In the validation process gas discharge lamps in accordance with their characteristics parameters input control additionally determine the compliance of their parameters on the spectral composition of the radiation to the nominal values of these parameters for plants grown in the greenhouse culture, and linking groups in the irradiation system is carried out lamps with the same parameters on spectral composition of radiation.

After the end of the vegetation period in the process of replacement of groups of lamps perform current control parameters in accordance with their parameters parameters on spectral composition of radiation for plants grown in the greenhouse. Of lamps held such control, produce the permutation groups and their use in subsequent cycles of vegetation.

Introduction the operation of the input control eliminates the possibility of operating lamps with parameters out of limits.

The holding current control together with activities, the permutation group of lamps will prolong the useful life, will provide confirmation of the parameters of the radiation regime in the greenhouse at the specified level.
