Guía técnica sobre los requisitos de certificación de la Asociación Internacional del Cielo Oscuro, ángulos de blindaje de luminarias y patrones de distribución de lúmenes para iluminación exterior conforme.
International Dark Sky Association Standards
IDA certification requires fixtures to emit zero light above 90° horizontal plane (0% uplight). Fixtures must also limit light trespass to adjacent properties: maximum 0.1 foot-candles at property lines for residential zones, 0.5 foot-candles for commercial zones. Bojing's BJ-Shield series meets all IDA Full Cutoff requirements.nts.
Fixture Shielding Requirements
Compliant fixtures use full-cutoff optics with minimum 15° shielding angle below horizontal. Reflector design must prevent light from escaping above the fixture's horizontal plane. Lens materials must be UV-stable polycarbonate or tempered glass to maintain optical performance over 10+ years.ars.
Lumen Distribution and Beam Angles
Dark Sky compliant fixtures typically use 40-60° beam angles to concentrate light on target surfaces. Wider 90°+ angles require additional shielding and are rarely compliant. Bojing offers 12 beam angle options (15° to 120°) to match specific landscape requirements while maintaining Dark Sky certification.
Color Temperature Restrictions
IDA recommends 2700K or warmer for outdoor lighting to minimize circadian disruption and wildlife impact. Fixtures with color temperatures above 3000K face restrictions in sensitive areas. Bojing's standard outdoor line defaults to 2700K with 3000K available upon request.est.
Certification Process and Documentation
Manufacturers must submit photometric data, fixture drawings, and installation instructions to IDA for review. Certification takes 6-8 weeks. Bojing maintains current IDA certification for 18 fixture models, with documentation available for specifier review.
