SSC studes find diode effective power saving device

by M Moraleda and D Deri

Sorsogon City (11 June) -- In the light of crafting ways to minimize electric power consumption, the fifth year electrical engineering students of the Sorsogon State College here, have finished a research study on Light Emitting Diode (LED) as an alternative electronic component in designing a lighting device.

The design proposed by Zendy Dematera, Dyronne P. Ajas, Gissell C. Dogillo and Rusan James Freo was adjudged best among the six competing groups and was given credit by the SSC in its recognition ceremony last March.

Engr. Joselito S. Orticio, who handles the students, said that the study was one of the requisites in their subject as well seminars and field trips where the students were exposed to.

"The research is only limited to the utilization of white LED which can possibly be an efficient source to replace the usual lighting system for domestic use," said Orticio.

The four researchers, after conducting the study, found out that it is possible to create a LED light bulb which can be directly connected to a 230V/.AC.

It was also proven to be energy-saving due to its low power consumption, producing a light output of 120.6 lumens and a power of 1.2 watts.

"It is also advantageous because its materials are more durable compared to the typical compact fluorescent lamps and bulbs which have fragile components. Furthermore, though costly, it has a longer lifespan and contains no mercury unlike other usual bulb designs," said the researchers.

Since it has poor illumination, they recommended the use of an efficient reflector that will suit the design of the bulb. "It is also imperative to utilized high-powered LED to make it a more effective lighting device," they also said. (SSC/PIA Sorsogon) [top]
