In the lighting field, the main concern is how to efficiently light projected onto the target surface, and the irradiation target on the way to achieve a particular lighting. Through a series of design and adjustment, to create a highly efficient LED lighting system, so that LED into peoples lives possible. This paper introduces the characteristics of LED lighting, light distribution, lighting a number of indicators and Program adopted, and to design LED lamps as an example, a regional division of thought on the LED lamp for optical design, LED light so designated to a specific area, through the illumination path of stacking area uniform illumination. ASAP software design results through simulation and actual measurement are met the requirements of road lighting standards. Keywords: LED lighting; Road lighting ; Secondary optics design; LED lamps 1 绪 论 1.1 引言 1879年，爱迪生发明了碳丝白炽
