ln this work a comparison is made between three generations of luminous devices, in order to have a quantitative estimation about the advantages of the new technologies on illumination sources based on Light Emitting Oiodes ...

The use of the Light Emitting Diode (LED) in broiler chicken production is a trend practically irreversible as it happened with the use of compact fluorescent light (FCL) in substitution of the incandescent lamps. As LED ...

The electricity consumption of households from all over Brazil is growing and it is known that lighting accounts for a good part of this demand is why there are encouraging the creation and use of more efficient lamps such ...

The commercial production of eggs demands artificial illumination for reproductive stimulation of birds. The lighting systems currently used have limitations when applied in aviaries and need improvements to enable energy ...

The influence of dentin permeability on transdentinal LED light propagation should be evaluated since this kind of phototherapy may further be clinically used to stimulate the metabolism of pulp cells, improving the healing ...
