Binay Opto Electronics Private Ltd. Offers Energy Conservation with Integral LED Modules. Binay Opto Electronics Private Ltd also manufactures LED based pilot lights, aviation obstruction lights, alarm lights, etc. Energy Conservation with Integral LED Modules is used for panel indication. These are essentially one-to-one replacements for different types of filament indication lights. The high reliability is basically due to the solid-state nature of the LED, which also lends it vibration-resistant and shock-proof properties in contrast to the fragility of conventional filament bulbs. If the LED circuit is properly designed, the diode will not be overloaded; most LED Modules can with-stand a voltage increase of more than 25V with no effect on the life.
