WL175 Series LED Overbed Light

COI (Cyanosis Observation Index) refers to the appearance of blue or purple color in the skin or mucous membranes. It measures color appearance changes by calculating the difference between fully oxygenated blood (100% oxygen saturation) and deoxygenated blood (bluish-purple blood at 50% oxygen saturation). The specific calculation method involves providing spectral reflectance data for both oxygenated and cyanotic blood, comparing it with a 4000K reference light source, and ultimately calculating the color difference in the CIE Lab* color space to determine the COI value.

This is a lighting fixture specifically designed for hospitals, featuring a unique optical configuration of COI<3.3, R9>50, CRI90, and SDCM<3, which enhances color rendering accuracy. The fixture offers four lighting modes: indirect lighting, direct lighting, indirect+direct lighting, and night light, all controllable via a pull switch. It has a scene memory function to meet various situational requirements. The body is made of AL6063 aluminum alloy, with a PC lampshade and high-efficiency 2835 LED chip. The surface adopts a high-gloss white paint, making it easy to clean and resistant to cleaning agents, suitable for use in hospitals, age care facilities such similar environments. Standard gloss anti-microbial white powder-coat finish, the primary defense is against Staphylococcus aureus ATCC 6538P and Escherichia coli ATCC 8739.
