This study has enabled to set an experimental bench allowing to extract the parameters of a high
power white LEDs. Then, a simple design for a current DC regulator is proposed. This DC driver has
been tested and has given a good regulation for luminaries composed of 20 LEDs. These experimental
results for regulation of current are in agreement with Pspice simulation. In perspective, this experimental
design and study will allow the development of a new driver with PWM technique. The LEDs luminaries
are a very promising technology for future development and deployment of photovoltaic lighting
applications.
