How to balance the artistry and comfort of the light environment in an architecturalized immersive new media public art installation (AINMPAI) to ensure the safety of the audiences’ visual safety has become a new issue. The lack of corresponding lighting design standards makes this issue more challenging. This paper explores the appropriate luminance range of the irregularly curved LED screens of the AINMPAI with high-luminance natural light as the background. The influence of the audience behavior mode on the brightness threshold of the LED screens in the AINMPAI under the background of Internet communication is discussed. Through software simulation and field measurement, the effectiveness of the design measures based on the local characteristics of the work is verified. The overall average luminance, the regional luminance, the partial luminance, and the corresponding luminance contrast of the inner screen surface were measured at every 10° change in the solar altitude angle during daytime. The nighttime light environment parameters and the temperature of the device throughout the day were also measured. A total of 487 visitors were interviewed for subjective evaluation of the comfort of the light and thermal environments. The results show that: (1) the overall average luminance cannot wholly describe the actual luminance of the critical parts of the special-shaped curved screen in the device and that two indicators, the regional luminance and the partial average luminance, need to be added; (2) the maximum brightness limit of LED screens in the daytime can be 1000 cd/m2 but at night it should be controlled within 200 cd/m2; (3) natural light is the main factor that causes the high average brightness and low contrast of the daytime device screen; (4) the recommended indicators for such artistic installations should balance the absolute values of average brightness, artistic effect, and transmission priority. This study can provide foundational data and a methodological reference for establishing AINMPAI light environment design guidelines or recommended standards based on audiences’ visual safety. |
