LED Indication Lamps for Electrical Panels

Panel indicators are optoelectronic devices which emit light to show the operating condition of a machine or appliance. The indicator light is a panel-mounted lamp assembly consisting of the indicator housing, an internal lamp, terminals, and a lens. The light source of indicator light is a high brightness pure color LED

As the name implies, indicator lights reveal the status (ON or OFF) of an electrical apparatus in switchboards.

LED are used in indicator lights due to the following reasons:

LEDs are used when the heat generated by incandescent lamps would damage nearby equipment or interfere with a precision process. This is particularly advantageous when multiple lights are grouped.
LEDs can operate at low temperatures which would cause incandescent lamps to fail since glass cracks during rapid cooling.
LEDs consume 50 times less power than incandescent lamps, thereby reducing energy consumption.
LEDs last 500 times longer than incandescent lamps. LEDs average a million hours (114 years) while incandescent lamps average 2000 hours.
LEDs do not generally “blow out” unless subjected to a severe overvoltage. They exhibit a half-life type diminishment in brightness over time. After 50,000 hours (6 years) of use, LEDs will retain approximately half of their original intensity.
LEDs have high visibility.
LEDs require little or no maintenance because of their long life and high reliability.
