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 energy management in urban and interurban lighting is currently, mainly, based on a centralised or clustered model. The control is mainly based on the level of brightness needed to circulate, without taking into account ...

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 ...

Energy consumption due to the economic development of countries impacts directly on the environment and causes investments in the power generation conventional or alternative infrastructure. Lighting systems are responsible ...

Among the fundamental factors for the economical development of a region it is the public lighting, which today is performed by application of different technologies. The lack of standardization in this sector results in ...

In this paper a case study was developed on the lighting situation of public buildings circulation spaces. Compliance with current standards and the need for adjustments for energy efficiency were also analyzed. For this, ...

This paper presents a case study about the lighting condition of the circulation areas of a public building. Regulatory compliance was verified and, if necessary, changes are proposed aiming at greater energy efficiency. ...
