This invention has already received the Sri Lankan Patent (No 18447)

Kelum Perera, who graduated from the Department of Physics and Electronics, University of Kelaniya, has invented a remote controlled regulator for ceiling fans. The device can be controlled using a mobile phone, thanks to the scientific research he has been engaged in since 2014. 
Perera, who did research in order to assemble a ceiling fan regulator for the first time, is presently pursuing his PhD in Kent State University in USA.

Professor S. R. D. Kalingamudali of the Department of Physics and Electronics, University of Kelaniya said that the significance of this invention underscored the fact that a mobile phone could be used to operate more than one ceiling fan at any give time.
The Research Council of the University of Kelaniya is conducting research on a number of inventions.

As a result of the research conducted by the Department of Physics and Electronics, this creation has successfully been acknowledged as an invention in November 2014.
