چکیده
The article is devoted to the study of influence different modes LED lamps color temperature in high-speed lighting conditions 2C:5T:3C:2T:3C:9T on productivity and viability, quality cross "Shaver" hens’ eggs. 4 radiation were tested: 1st group-in all periods light 3000 K; 2nd group-the first last K, average period 5000 3rd group 4-the half each second K. It was found that groups 1, 2, 3 with high bird safety (99-100%), egg production per 1 laying hen 148.6, 141.8, 155.5 140.5 pieces; weight-61.2, 60.9, 62.3 60.9 g; weight yield hen-8.99, 8.55, 9.56 8.47 kg; feed consumption kg weight-3.31, 2.43, 2.24 2.40 kg. According complex zootechnical indicators, recognized as best, which also surpassed other absolute relative yolk (15.04 g 24.35% vs. 14.16-15.04 23.31-24.35%), protein (40.50 38.98-39.88 g) slightly inferior shell (6.73 10.78% 6.83-6.92 11.08-11.39%).

New Framework of Sustainable Indicators for Outdoor LED (Light Emitting Diodes) Lighting and SSL (Solid State Lighting)
Light emitting diodes (LEDs) and SSL (solid state lighting) are relatively new light sources, but are already widely applied for outdoor lighting. Despite this, there is little available information allowing planners and designers to evaluate and weigh different sustainability aspects of LED/SSL lighting when making decisions. Based on a literature review, this paper proposes a framework of sus...
متن کاملOrganic Light Emitting Diodes: Devices and applications
Opto-electronic devices using organic materials are becoming widely desirable for manifold reasons [1-4]. In fact, organic devices have the potential for cost advantages over inorganic devices. In addition, inherent properties of organic materials, such as their flexibility make them well suited for particular applications such as fabrication on a flexible substrate. The materials used in organ...
متن کاملLight-emitting diodes (LED) for domestic lighting: any risks for the eye?
Light-emitting diodes (LEDs) are taking an increasing place in the market of domestic lighting because they produce light with low energy consumption. In the EU, by 2016, no traditional incandescent light sources will be available and LEDs may become the major domestic light sources. Due to specific spectral and energetic characteristics of white LEDs as compared to other domestic light sources...
متن کاملPrinted Inorganic Light Emitting Diodes for Solid State Lighting
In this paper we present a new form of inorganic printed electronics (PE) that overcomes many of the problems associated with the act of printing electronics. The technique allows for very high speed, inexpensive production of PE products. To illustrate this approach we will describe a solid state lighting (SSL) device based upon a standard InGaN heteroepitaxy and fabricated as micro LEDs dispe...
متن کاملTemperature-dependent photoluminescence in light-emitting diodes
Temperature-dependent photoluminescence (TDPL), one of the most effective and powerful optical characterisation methods, is widely used to investigate carrier transport and localized states in semiconductor materials. Resonant excitation and non-resonant excitation are the two primary methods of researching this issue. In this study, the application ranges of the different excitation modes are ...
