With the improvement of digital literacy among the elderly population, the market size of age-friendly smart home furnishings has reached RMB 150 billion yuan. However, existing smart lighting products for the elderly tend to focus on "sensory compensation", prioritizing safety functions over emotional needs, and health monitoring over cognitive support, thus failing to adequately meet the demands of the elderly for subjective interaction. Data were collected through focus group discussions and in-depth interviews to prioritize the demands of the elderly for lighting products. Based on the Stimulus-Organism-Response (SOR) theoretical model, a critical analysis was conducted on the missing procedural links in elderly users' experience with smart lighting products, interpreting the life histories of elderly users from an interactivity perspective, integrating individual experiences into product design pathways, and revealing the multi-dimensional influence mechanisms of light environment stimuli on the physiology, behavior, and emotions of the elderly. Additionally, the design element network of smart lighting products consisting of physique-material, somatosensory-interaction, and experience-service dimensions was analyzed to provide guidance for the practical development of smart lighting products for the elderly. The findings revealed that the design of smart lighting products for the elderly should proceed from a human factors and experience perspective, focusing on such core elements as perceptual usability, emotional adaptability, health visualization and digital accessibility. This design helped reduce the incidence of home accidents, enhance emotional well-being, realize the transformation from passive lighting to emotional care, and deliver a modular age-friendly smart lighting design centered on the concept of "body-centricity" as its value orientation. This study helps improve the utility of home furnishing products in the "silver economy", effectively bridge the digital divide among the elderly population, enhance their sense of technological acquisition, and provide strategic references for the development and innovation of age-friendly lighting products.
