T/FSLA 002-2021 Indoor LED downlight

Scope

Main technical contents: Luminous performance: The luminous performance specifies the initial luminous efficacy and color rendering index requirements, which are all higher than those stipulated in GB/T 29294-2012. Based on current LED technology, the following indicators can be achieved: 1. **Initial luminous efficacy**: - For rated correlated color temperature not exceeding 3500K, the luminous efficacy shall be no less than 80 Lm/W. - For rated correlated color temperature between 3500K and 6500K, the luminous efficacy shall be no less than 85 Lm/W. - LED products with high luminous efficacy are more energy-efficient. 2. **Color rendering index (CRI)**: - The standard specifies Ra ≥ 90 and R9 ≥ 50. A CRI higher than 90 effectively restores the true appearance of objects and alleviates visual fatigue. - For the first time, a special color rendering index R9 (saturation red light) is proposed to be no less than 50, ensuring that the product's color rendering is closer to the spectrum of natural light and meets human health requirements. - The test method follows the provisions of GB/T 24824. (3) **Safety**: Complies with the requirements of relevant mandatory national standards. (4) **Electromagnetic compatibility**: Complies with the provisions of GB 17743. (5) **Luminaire dimensions**: The diameter of the reflective cover of LED downlights shall have a deviation of ±3%. Other items shall comply with the provisions of relevant mandatory national standards. (6) **Photobiological safety**: To reflect the product's concept of healthy lighting and requirements, the photobiological safety of the lamp shall comply with the provisions of GB/T 20145 and IEC/TR 62778. The retinal blue light hazard group shall meet RG0 (exempt level), indicating it is an unrestricted light source or luminaire.
