T/NHLSAN 8-2019 LED ground-buried light
Basic Information
Scope
Scope: This standard specifies the terms and definitions, classification and naming, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage of LED buried lamps. This standard applies to LED buried lamps powered by AC or DC sources below 250V, used for outdoor lighting or decoration in squares, parks, leisure venues, and other outdoor environments. This standard does not apply to LED buried lamps installed on motor vehicle lanes and airport runways as specified in IEC 61827. Main technical content: The main technical content of LED buried lamps includes: environmental adaptability, appearance, electroplating and chemical coatings, salt spray, photoelectric performance (shading angle, power, power factor, initial luminous flux, initial wavelength, initial luminous efficiency, color temperature, beam angle), lifespan (average lifespan, luminous flux maintenance rate, switching cycles), safety, photobiological safety, vibration, and electromagnetic compatibility.
