Artificial lighting in areas of natural and astronomical interest must meet stringent lighting requirements that to date were only met by sodium-vapour lamps.

Protecting the night-time environment


The use of PC-amber LED lights in these spaces opens previously inimaginable possibilities for controlling light pollution, as the light source emits almost no radiation below 500 nm (<0.6%). The team of Ignialight engineers, in cooperation with leading experts in preventing artificial light from affecting the environment –IAC (Astrophysical Institute of the Canary Islands), UM (University of Murcia), CIS (Spanish Lighting Commission) and IREC (Engineering Research Institute of Catalonia)– have been pioneers in designing a product that protects the night-time environment by applying PC-amber technology for public lighting systems. Features of PC-Amber LEDs
• The emission spectrum is below 500 nm. This decreases the harm the lamps have on the night-time environment by 70% compared with mercury-vapour and 30% compared to high-pressure sodium-vapour.
 • A significant amount of light pollution is limited, which improves the quality of the night-time environment.
 • They comply with the regulations on existing limitations in lighting E1 and E2 areas (areas with maximum protection from light pollution), focusing the light mainly on wavelengths longer than 525 nm and <1% UFF (upper flux faction, the luminous flux emitted in the upper hemisphere).
• Environmentally-friendly lamp. Wildlife is more sensitive to blue light, while the more orange light emitted by the PC Amber LED is virtually invisible to them and has no effect on their life cycles.

Ignialight PC Amber lamps have proven their suitability for public lighting projects in areas of natural and astronomical interest that require protection of the night-time environment.
