Modular Design Using Sustainable Luminescent Materials in Energy-Saving Reflective Cat’s Eyes for Public Road Safety Planning

Abstract

Recently, there has been a global movement toward environmental protection and energy conservation through the design and development of new products in accordance with sustainable utilisation. In this study, rare earth luminescent materials were used owing to their active light emission and reusability. Additionally, solar lightemitting diode lights and car-light reflection were utilised to increase the recognition and reliability of reflective cat eyes. Along with carbon reduction, this can save energy and enhance road safety. This study considered the Theory of Inventive Problem Solving and a literature review to analyse the issues in existing products. Then, expert interviews were conducted to screen projects and develop product design policies. Finally, the ratio of light-storage materials was experimentally determined and the prototypes implemented. This cat's eye addresses the shortcomings identified in previous analyses of existing products. We applied energy storage environmental protection materials, together with material proportioning (which balanced warning efficiency against cost-effectiveness) to develop diversified modular kits; these were flexible in terms of quantity and easily assembled. This study achieved four key objectives: (1) reducing the research and development costs of the manufacturer; (2) offering buyers a diverse suite of products; (3) responding to a need to improve diverse road user safety; and (4) reducing government procurement costs for safety warning products. The results provide a reference for the creative modular design of energy-saving products for public road safety planning in various industries.

Can Potted Plants Catch Mosquitoes? Applying Rare-Earth Luminescent Materials and Plant Energy to the Development of Innovative Mosquito-Trapping Potted Plants

“…According to the experimental results of previous studies, the rare-earth material with composite material is epoxy AB. According to the results of previous experiments, a good luminescence effect and cost-effectiveness can both be achieved when the rare-earth material with composite material epoxy AB is used at a ratio of 35:65% [ 39 ]. Moreover, the light storage powder tends to remain in a particulate state and cannot be completely dissolved at a ratio of over 40%.…”

“…Rare-earth luminescent materials provide green lighting with less pollution and are widely used in warning sign systems at construction sites, expressways, urban streets, airports, ships, and hospitals [ 34 , 35 , 36 , 37 ]. The advantages of rare-earth luminescent materials include stability, high-temperature resistance, highly pure and bright colors, high light conversion efficiency, and strong absorptive capacity [ 36 , 38 , 39 ]. Rare-earth luminescent materials can store energy during the day and emit light at night or under low-light conditions.…”
