Study on equal brightness and adjustable color temperature LED lamp
Abstract
The white LED has the advantage of high luminous efficiency, low power consumption, long life, environmental protection. The other traditional lighting sources can not match the above advantages. Therefore the white LED is considered to replace incandescent and fluorescent lighting. In this paper, semiconductor lighting source, based on the current progress of the latest research, is introduced in indoor application of GaN-based white LED lighting. After discussing the visual indicators, optical parameters, packaging technology, the cost, this article also points out that the white LED lighting in the day-to-day popularity of the course as well as color temperature adjustable LED lamp applications, some of the main issues, and these issues and has done a detailed analysis and discussion. Then, existing and possible solution, development prospects of further prospects. In this way, equal brightness and adjustable color temperature table lamp study the more general trend
