Abstract：This study surveyed the lighting environment in Cardiac Intensive Care Unit ( CICU ) .The results indicated that: 1 ) the illuminance is lower than required; 2 ) improper lighting modes cause discomfort glare;3 ) the light distribution of the lamps is not optimized;4 ) the light sources are at cool white color temperature . All the situations above caused visual discomfort to the patients and staff . Therefore, the main purpose of this study is to find a healthy lighting condition in CICU which is good for the visual comfort .A simulated CICU with different lighting scenarios was built .This work studied the impact of illuminance and lighting modes on patients and staff ’ s satisfaction at color temperature of 4000 K by subjective questionnaires and physiological data .The results showed that: 1 ) patients ’ satisfaction reached maximum at illumination of 200 lx;2) the proportion of indirect illumination is positively correlated to the degree of patients ’ satisfaction at a certain illumination level; 3 ) the illumination was positively correlated to staff’s satisfaction when the illumination levels were 100, 200 and 400 lx; 4) there is no significant linear correlation between different lighting modes and staff ’ s satisfaction at a certain illumination.
