摘要

正如本文第1部分所示,由于客观设计缺陷,现代头部照明并不总是符合现有国际标准的要求,这意味着道路安全性的降低。消除以前的多波束类型。这些类型的大灯目前要么正在进行生产测试阶段,要么就生产单位的数量而言,用于极为有限批次的车辆。根据分析的结果,对先进的头部照明的设计提出了建议。这些建议的主要内容是使用带有全内反射反射器的单个高功率led,这将提供一个锐利的截止边界,并有效地利用光源光通量。为了增加前照灯对温升的抵抗力,建议将led或其他经济光源与荧光粉部件一起使用。研究表明,车辆前照灯的适应性是一种有用但可选的特性,因为它会导致设计复杂化,这并不总是合理的。考虑到上述建议,描述了前照灯的优点,主要是其设计的简化,重量的减轻和产品热参数的改进。

Current State and Prospects for Development of Head Lighting for Vehicles. Part 2. Advanced Designs for Vehicle Headlights
As it has been shown in part 1 of this paper, modern head lighting, due to  objective design flaws, does not always meet the requirements of existing international  standards, which means a decrease in road safety. To eliminate the previously Multibeam type.  These types of headlights  are currently either undergoing the stage of production tests or are used in extremely limited batches of vehicles in terms of the number of produced units. According with the results of this analysis, recommendations have been formulated for the design of advanced head lighting. The main of these recommendations is the use of single high-power LEDs with total internal reflection reflectors, which will provide a sharp cut-off border with efficient use of the source light flux. To increase the resistance of the headlight to temperature rise, it is proposed to use LEDs or other economical light sources together with phosphor parts. It is shown that adaptability is a useful but optional property of vehicle headlights, since it leads to complicate the design, and this is not always justified. The advantages of the headlight, created taking into account the above recommendations, are described, the main of which are the simplification of its design, reduction in weight and improvement of the thermal parameters of the product.
