Since 1988, with the introduction of the Spanish Act 31/1988 (Ley 31/1988) on the Protection of the Astronomical Quality of Canary Islands Institute of Astrophysics (IAC) Observatories, commonly known as the "Sky Act", external lighting manufacturers have become increasingly aware of the polluting effects (as regards lighting) of different light spectra based on colour temperature, upper hemisphere emissions, type of light source, etc.
To complete our available options, when it comes to complying with the most restrictive regulatory conditions, we present the AVATAR solution with an AMBER diffuser option. The main aim of this solution is to filter the unwanted area of the spectrum to comply with regulations by taking advantage of the latest developments in the luminous flux of high-power ceramic-based 3535 LEDs. This makes it possible to increase the power of traditional lights with PCA LEDs, improve flux and optimise costs.
The advantages of the new AVATAR solution with an amber diffuser option include:
When we talk about light pollution generated by artificial light in very restricted terms and without considering technical complexity, we see it as how certain wavelengths in lighting systems interact with the surrounding environment and biodiversity.
To avoid this type of pollution as much as possible, we must adopt measures such as keeping light flows to the upper hemisphere to a minimum and optimising light emissions in the blue section of the spectrum (which experiences greater RAYLEIGH dispersion in clean air and MIE dispersion in air containing aerosols).
To create regulations that people can understand and that engineers and public officials can apply, Spain has several different regulations in this area, including:
All the above regulations, with small variations, limit the amount of "blue" in a lighting system's colour spectrum and restrict how much light enters the upper hemisphere.
At PRILUX, we want to help you make decisions to comply with any of these regulations, both in new works and when replacing or maintaining systems that have already been installed. That is why we have created this compliance chart based on the characteristics of the LED used.
