Abstract:
To establish a foothold in the global market for traffic safety reflective signs, it is essential to develop a flat cube reflector that adheres to the regulatory standards set by both the United States Society of Automotive Engineers (SAE) and the Economic Commission for Europe (ECE). These standards primarily differ in terms of the specified observation angle and reflector value, with SAE requiring an observation angle of 0.2 degrees and ECE mandating 0.33 degrees. Leveraging sophisticated software tools, including SolidWorks, TracePro, Speos, LightTools, and Optiswork, allows for the meticulous optimization of the flat cube reflector to maximize its reflectivity. This optimization involves the precise arrangement of pins within the reflector, oriented unidirectionally. Our findings highlight the innovative potential of a singular flat cube reflector design that can simultaneously meet the stringent standards of both SAE and ECE. This dual-compliance capability holds significant promise for cost savings in the production of reflex reflectors intended for the European and American automobile markets.
