Domestic manufacturers producing various types of road lighting fixtures are quite numerous. Currently, in the high-power LED solar road lamp segment, some factories have started development attempts. However, simply combining multiple chips or multiple devices makes it challenging to meet national standards concerning actual illumination area and uniformity of effective brightness. Consequently, this prevents the application of LED solar road lamps in branch lighting and secondary road lighting, thereby limiting their use on main roads. If power is forcibly increased to meet these standards, the high-efficiency characteristics of LED solar road lamps would be lost.
To design an optical system suitable for semiconductor road lighting, the critical issue is to create an effective and reliable optical system that ensures the light emitted by the source is evenly distributed across the road surface. This addresses the problem of orderly light energy transmission, which is a primary research direction of non-imaging optics, specifically the design of optical systems with a given illuminance distribution.
Non-imaging optics has gradually evolved over the past few decades as a specialized branch dedicated to studying light energy transmission issues. It mainly enhances energy transmission efficiency by designing refraction and reflection surfaces to “orderly” control the light in the optical system.
Under the approximation of point light sources, the solution to the given illuminance distribution problem can be abstracted into a mathematical model. However, when this problem is considered in three-dimensional space, it transforms into a highly complex second-order nonlinear Monte Carlo partial differential equation. Various methods have been employed to study solutions to this equation. Given the complexity of the solving process, the solutions obtained under specific boundary conditions lack practical value and do not yield usable optical systems.
Our research provides a novel solution and theoretical basis for addressing the given illuminance problem in non-imaging optics. This will facilitate the application of non-imaging optics in the design of optical systems for semiconductor lighting, enabling better collection and utilization of wide-angle light emitted by the source. It aims to exploit the potential of LED solar road lamps and design new LED solar road lamp lighting systems, enhancing the light efficiency of the system and establishing intellectual property. The new theories and methods will also apply to the design of non-imaging optical systems for other semiconductor lighting applications, such as automotive headlights, projector light sources, and backlight designs utilizing LED solar road lamps.
Therefore, there is a significant potential for improving transmission efficiency by modifying road lighting structures. A practical approach is to design special optical systems based on the principles of non-imaging optics, enabling a more reasonable distribution of the light energy emitted by LED solar road lamps. This can improve the performance of road lighting systems while meeting national standards for illuminance and uniformity, maximizing energy utilization.
