Our previous research applied a classification-integrated moving average (CIMA). This intelligence method improves the performance of passive infrared (PIR) sensors in smart lighting to make control more comfortable for user. However, intelligence, synonymous with use cloud and large latency, contradicts real-time nature demanded by lighting. paper proposes edge (EdgeSL) architecture, an edge-computing architecture improved CIMA control. We developed novel intelligent using permutation importance feature selection improve algorithm. Three model compression methods k-nearest neighbor (KNN) are compared, including knowledge distillation on KNN called DistilKNN. The is basis CIMA. allows run environment. experiment was carried out evaluating processing time three different environments, namely edge, fog, architecture. test results show that DistilKNN has best accuracy compared other methods, pruning quantization, which 0.93. After deploying compressed NodeMCU, computing lower than fog computing, 9.0, 60.1, 207.6 ms, respectively. going through Shapiro-Wilk test, we learned times not normally distributed. So after testing Wilcoxon it proved EdgeSL performance, where architectures significant differences.

This paper proposes energy-efficient solutions for the smart light-emitting diode (LED) lighting system, which provides minimal energy consumption while simultaneously satisfying illuminance requirements of users in a typical office space. In addition to artificial light from dimmable LED lamps, natural daylight coming external sources, such as windows, is considered source illumination an indoor environment. order reduce total consumption, system has possibility dim resulting reduced output power. Additionally, various lamps' functionality, semi-angle half and tilting, are introduced additional parameter be optimized achieve greater saving designed system. properly exploit lighting, idea overall intensity at users' location realized by option windows with shading factor. Based on desired level illumination, proposed optimization problems can solved implementing different algorithms. The obtained able give instructions manage control parameters (LEDs dimming levels, semi-angles illuminance, orientation LEDs, factor) design ensures satisfaction related requirements.

Visual fatigue has become a public health issue, while the relevant retinal mechanism and characteristics of blue light that induce visual have been rarely studied. In retina, both short wavelength-sensitive (S) cones melanopsin-containing intrinsically photoreceptive ganglion cells (ipRGCs) are sensitive to light, their responses opposite in pupil mediation. Thus, effects blue-enriched white with different S-cone-opic Equivalent Daylight Illuminance (EDI) on was investigated, maintaining same melanopic EDI avoid interferences ipRGCs. Two illuminants (one low EDI, other high EDI) were characterized based α-opic correlated colour temperature illuminance. Melanopic lower than these two illuminants. Psychological, visual, physiological cognitive performances measured investigate fatigue. Results showed can Participants felt more discomfort eyes under along decline tear film stability changes heart rhythm. Furthermore, reaction time memory task increased significantly EDI. The findings provide new insights into optimization indoor lighting environments for human health.

Electric lighting plays a critical role in buildings, not only impacting the well-being, satisfaction, and performance of building occupants but also accounting for significant portion energy consumption. The commonly used efficiency metrics lighting, such as luminous efficacy or power density, fall short quantifying effective light architectural spaces. To address shortcomings existing measures, application that characterizes efficient delivery from source to target should be utilized. Lighting can account efficiencies temporal, electrical, visual, spatial dimensions. This study outlines method quantify electric buildings. As proof concept, simulated data are analyzed two targets (horizontal work plane level occupant field view) based on primary characteristics built environment systems. findings indicate design variables (e.g., room size, luminaire distribution type, reflectance surfaces, significantly affect specified settings. Therefore, values exhibit considerable variation among distinct systems spaces customized suit unique requirements each setting. Future research will investigate establish complementary components framework.
