“…The sodium vapor lamp had a wider range, indicating that it is necessary to use fewer units in the shed. This result is consistent with studies conducted by JÁCOME (2009) and JORDAN & TAVARES (2005), which compared different types of artificial lighting for egg laying production. When evaluating lighting technologies for the production of chrysanthemum cuttings, DAVID & ROSSI (2010) also used fewer sodium vapor lamps than other treatments.…”

“…For the illuminance of 5 lux, SVL and CFL showed no significant difference in active demand, but as CFL has a lower power factor, which brings more reactive demand, SVL had a better result by presenting lower apparent demand. JORDAN & TAVARES (2005), analyzing different types of lamps to produce fertile eggs, verified that the sodium vapor lamp 70W offers major advantages, because it showed a 76% savings compared to incandescent 100W. JÁCOME (2009), comparing incandescent lamp 100W (control) with sodium vapor lamp 70W, found a 54.14% reduction in demand, and comparing the control with compact fluorescent lamp 23W, the reduction was 73.76%.…”

“…Systems equipped with light fixtures showed less uniformity and higher frequency of luminance above the ideal. JORDAN & TAVARES (2005) report that situations like this can be detrimental to broiler production, favoring the development of aggressive behavior, hyperactivity and cannibalism, and also causing fat deposition, higher incidence of leg problems, metabolic and circulatory diseases. JÁCOME (2009) observed a lower egg production when hens were exposed to high illuminance.…”

“…Considering the overlap of the luminous flux, these are the points with lower levels of luminance in the experimental plot (Figure 1). No theoretical method for calculating light levels was adopted as literature reports some inconsistency between the data measured and estimated (DAVID, 2007;JORDAN & TAVARES, 2005). When using IL, CFL and ML lamps, three lines of lamps were required to meet minimum illuminance of 20 lux.…”

“…In poultry production chain, the energy is the second most used input, where feed is the first. The lighting of the building, in most cases, is responsible for major loss (JORDAN & TAVARES, 2005). TURCO et al (2002), by measuring the energy consumption of equipment (feeders, fans and lamps) of a poultry house, during 40 days, during the winter, found out that 55% of the total energy consumed was due to the lighting system.…”

ABSTRACT:The spatial distribution of illuminance and the electric consumption of artificial lighting system is one of the main problems related to broiler production. Therefore, the aim of this study was to evaluate the spatial distribution of luminance level and energy efficiency of different lighting systems for broiler houses. Six types of lamps were tested in two different configurations to find the minimum illuminance of 20 and 5 lux. The tested lamps were incandescent (IL) 100 W, compact fluorescent (CFL) 34 W, mixed (ML) 160 W, sodium vapor (SVL) 70 W, T8 fluorescent tube (T8 FTL) 40 W and T5 fluorescent tube (T5 FTL) 28 W. The first four were evaluated with and without reflective light fixture and the latter two without light fixture. It was observed that the tested system with light fixtures negatively affected the spatial distribution of illuminance inside the house. The systems composed by IL and ML without light fixture led to better results in meeting the minimum illuminance of 20 lux and 5 lux, respectively. T5 FTL presented the lowest energy demand.KEY WORDS: artificial lighting, spatial variability, energy efficiency, aviculture. AVALIAÇÃO TÉCNICA DE SISTEMAS DE ILUMINAÇÃO PARA GALPÕES DE FRANGOS DE CORTE RESUMO:A distribuição espacial das iluminâncias e o consumo de energia elétrica do sistema de iluminação artificial constituem um dos principais problemas relacionados à produção de frangos de corte. Portanto, objetivou-se com o presente trabalho avaliar a distribuição espacial do nível de iluminância e a eficiência energética de diferentes sistemas de iluminação para galpões para criação de frangos de corte. Seis tipos de lâmpadas foram testados em duas configurações diferentes para atender às iluminâncias mínimas de 20 e 5 lux. As lâmpadas testadas foram a incandescente (LI) de 100 W, fluorescente compacta (LFC) de 34 W, mista (LM) de 160 W, vapor de sódio (LVS) de 70 W, fluorescente tubular T8 (LFT T8) de 40 W e fluorescente tubular T5 (LFT T5) de 28 W. As quatro primeiras foram avaliadas sem e com luminária reflexiva tipo prato, e as duas últimas apenas sem luminária. Para os sistemas testados, verificou-se que o uso de luminárias afetou negativamente a distribuição espacial das iluminâncias no interior do galpão. Os sistemas compostos por LI e LM, sem luminária, propiciaram melhores resultados para se atenderem as iluminâncias mínimas de 20 lux e 5 lux, respectivamente. A LFT T5 apresentou os menores valores de demanda de energia. PALAVRAS-CHAVE:iluminação artificial, variabilidade espacial, eficiência energética, avicultura.

The objective of this study was to evaluate the performance of broiler chickens in different lighting programs. Broiler chickens were fed on feeders of different colours at different breeding phases. In total, 240 Cobb500™ chicks mixed at 1 d of age were used. They were distributed in a completely randomized design. The treatments followed a 2 × 4 factorial design: two lighting programs (continuous and intermittent), and four colours of feeders (white, green, blue, and red). The birds were evaluated for weekly productive performance and the data were submitted to analysis of variance and later Tukey’s test for comparison of means. In the periods 1–7, 1–21, and 1–42 d of age, lighting programs and feeder colours affected weight gain, feed intake, and feed conversion. Intermittent red feeders influenced positively the performance of birds. It is possible to replace conventional lighting programs for intermittent lighting programs. Red feeders exert a positive influence on the performance of broiler chickens.

Broiler poultry is highly dependent on artificial lightening. Power consumption costs of artificial lighting systems is the second largest expense related to broiler industry, second only to feed expenses. Therefore, the current study focused to analyze technical and economic feasibility of replacing incandescent lamps already used in aviaries with other lamp types. Costs related to power consumption, implementation and maintenance of the lighting systems were evaluated with the aid of financial mathematics using net present value, return over investment and payback. Systems composed of six lamp types were analyzed in two different configurations to meet the minimum illuminance of 5 and 20 lux and for use in conventional sheds and dark house. The lamps tested were incandescent (LI) of 100 W, compact fluorescent (CFL) of 34 W, mixed (ML) 160 W sodium vapor (SVL) of 70 W, tubular fluorescent T8 (TFL T8) of 40 W and tubular fluorescent T5 (TFL T5) of 28 W. For the systems tested, it was found that the tubular fluorescent lamps T8 and T5 showed the best results of technical and economic feasibility.

ANÁLISE TÉCNICO-ECONÔMICA DE DIFERENTES SISTEMAS DE ILUMINAÇÃO PARA AVIÁRIOS DE FRANGOS DE CORTERESUMO: A produção de frangos de corte é altamente dependente do uso de luz artificial. O custo do consumo de energia elétrica do sistema de iluminação artificial constitui a segunda maior despesa relacionada à produção de frangos de corte, inferior apenas às despesas com ração. Portanto, objetivou-se com o presente trabalho analisar a viabilidade técnico-econômica de se substituir a lâmpada incandescente utilizada nos aviários por outros tipos de lâmpada. O consumo de energia e os custos de implantação e de manutenção dos sistemas de iluminação foram avaliados com auxílio da matemática financeira, por meio do valor presente líquido, da taxa de retorno do investimento e do tempo de retorno do capital (payback). Foram avaliados sistemas compostos por seis tipos de lâmpada, em duas configurações diferentes, para atender às iluminâncias mínimas de 5 e 20 lux e para a utilização em galpões convencionais e dark house. As lâmpadas testadas foram a incandescente (LI) de 100 W, a fluorescente compacta (LFC) de 34 W, a mista (LM) de 160 W, o vapor de sódio (LVS) de 70 W, a fluorescente tubular T8 (LFT T8) de 40 W e a fluorescente tubular T5 (LFT T5) de 28 W. Para os sistemas testados, verificou-se que as lâmpadas fluorescentes tubulares T8 e T5 apresentaram os melhores resultados de viabilidade técnica e econômica. PALAVRAS-CHAVE:análise econômica, avicultura, eficiência energética, iluminação artificial.
