Abstract

This paper describes a complete design and implementation of a low cost digital controller for a high power LED driver. The main advantages of high efficiency LEDs are their good luminosity, efficiency and long life. Due to these improved behaviour, the number of LED-based applications is increasing. Nowadays, the cost of digital processors is continuously decreasing, and the trend is that still lower costs will be achieved in the future. In addition, digital processors offer extra features, e.g. communication protocols, software protections, and so on. Therefore, this study has an increasing practical interest. Design guidelines for a LED based light supply with digital control are proposed A prototype has been built and tested, and results are shown to validate the design approach.
