Introduction of led lights in livestock premises

This article presents research on the introduction of LED lamps in livestock premises. The work was carried out in the conditions of the economy of the Grigorievskoye Federal State Unitary Enterprise of the Yaroslavl region. Modeling and forecasting of the illumination of the aft table was carried out by calculation in the DIALux evo software package. The scheme of the developed lamp SP-1 was formed using a new development of LEDs with a light output of at least 150 lm/ W. The developed lamp SP-1 simulates sunlight in the wavelength range of 380-800 nm, the reproduction accuracy of the solar spectrum is 70%. To verify the reliability of the simulation data, it was decided to conduct full-scale tests in a building under construction for keeping young cattle. LED lights were placed in the calf house at the distances and heights specified in the simulation model. Next, an array of data on the illumination of the room was collected and the average illumination values at the selected points were found. The analysis of the obtained data revealed that the convergence of the simulation results and experimental measurements reaches 97.5%. The advantages of the proposed device are revealed, such as: power consumption – 9 W, light output– 133 lm/W, price – 3772 RUB. It is determined that the illumination varies and over the feed table is 118.4 – 120.0 lux, and for the rest of the calf is 82.4 – 94.5 lux.
