Question

Write a short note on energy efficient lighting and control
​

Answer 1

Answer:

Energy efficient lighting includes the use of more illumination from less power lights by replacing high power consumption lights like incandescent, high discharge lamps, etc. This is also used in various control technologies like GPRS or GSM or SCADA based controls. It is also replacing high power lighting accessories by low power devices such as electronic ballasts, fixtures, etc.

Another key for reducing energy consumption is using the light energy as much as needed with available lights. This is possible by keeping various sensing devices to switch the lights such as motion sensors, infrared sensors, automatic timers, etc. These sensors sense the day light availability, presence of humans and other living species, instruction for remote operating, etc.

Accessories of lamps such as ballasts, fixtures, etc also play an essential role in energy saving. Ballasts or chokes to be installed with lamps, including non integrated ballasts in CFL bulbs should be electronic or low loss copper ballasts to save some extent of energy compared to conventional ballasts. This also improves the power factor.

New way to save energy is by using energy efficient fixtures which uses 75 percent less energy than standard incandescent ones. These fixtures not only increase the illumination by low energy consumption but also protect the lamps for longer life.

Hope it helps :)
