T/ZALI 0003-2018 LED lighting technology specifications for medical buildings

Scope

Scope: This standard specifies the indoor lighting requirements and test methods for LED lighting products (hereinafter referred to as "lamps") in medical buildings, as well as the requirements for the safety, performance, efficiency, and control systems of the lamps. This standard applies to LED lighting in newly built, renovated, and expanded medical buildings. This standard does not include requirements for special lighting such as LED emergency lighting, LED medical signage lighting, and dedicated LED shadowless lamps for operating rooms. Main technical content: Good lighting can create a visual environment that enables people to perform visual tasks efficiently, accurately, and safely without causing visual fatigue or discomfort. Lighting can be provided by natural light or electric light sources, or a combination of the two. Good lighting includes both the quality and quantity of illumination. In addition to the illuminance requirements on the work surface, the evaluation of lighting quality such as environmental contrast, glare level, color characteristics, flicker effect, and photobiological safety is indispensable. This standard proposes various parameters for establishing comfortable visual conditions in different workplaces and task types in medical buildings that apply LED lighting products, and specifies illuminance, uncomfortable glare limit levels, light source color temperature and color rendering index, as well as efficiency requirements.
