LED灯的结构特点及应用

作为优质高效的照明光源,LED灯的广泛应用将为现代社会提供更加优良、环保的照明环境和高效、节能的照明品质,并且替代白炽灯的应用。由于LED灯和白炽灯泡两者的发光原理、结构方式及使用特性截然不同,因此在替代应用时需要加以研究和探讨。文章主要从白炽灯的结构着手,依据LED灯自身的特点,并结合具体的应用,重点分析了LED灯的配光、散热的结构方式、驱动电源的性能特点,以及存在的一些问题。同时给出了替代应用时所要考虑的环境要求以及选择方式。对于今后LED灯更加广泛的应用等具有积极的意义。

The Construction Features of LED Light and Its Application

As a high quality and efficient lighting source, the extensive application of LED light will provide environmental protection lighting environment that has higher efficience and energy saving and good lighting quality for modem society. Because of complete differents of luminous principle, structure mode and the characteristics of usages of both LED light and incandescent light, we need to study and discuss the ahema- tive application. To begin the structure of the incandescent lamp, the characteristics of LED light and with the specific application, this article mainly analyses the construction of light distribution, the structure mode of heat dissipation and the characteristics of the drive power supply, and also puts forward some existing prob- lems. At the same time, the article points out the requirements of the application environment and the choice of the alternative application. These will have more positive significance to obtain more extensive application of LED light in future.
