The advantages that solid-state LEDs offer are particularly suitable for the
utility industry where numerous lamps provide critical indication in control
panels. Burned-out incandescent bulbs require continuous, costly maintenance and
create safety concerns. But why then have only a limited number of utilities
replaced incandescent indicators with LED lamps? This paper will show how
wide-spread panel lamp replacement with led flood light technology provides a payback in
less than 12-months. This paper also discusses the issues of reliability and
safety for critical indication applications.
The primary benefit of LED technology is the tremendous cost savings for the user as a result of eliminating replacement cost, lowering power consumption, and reducing operating temperatures. Moreover, LED lamps improve efficiency by providing reliable status indication.
LEDs generally draw much lower current than incandescent bulbs. While lower power consumption reduces operating costs, it also reduces wear on other components in the application such as transformers, batteries and power converters.When cold, an incandescent filament draws ten times as much current as it does during normal operation. The initial powering of hundreds of incandescent bulbs simultaneously causes significant voltage surges that lead to lamp failures.
There are several sources of leakage current in a circuit. Transient voltage from a relay or discharge from a capacitor creates circuit noise. Also, inherent in the design of some programmable logic controllers (PLCs), is a triac protective circuit that may supply up to 5mA of leakage current in the off state.Based on an average incandescent bulb life of three months, converting to LEDs will pay for itself in material costs alone within the first year. This payback period is only considering the cost of the incandescent bulb. It does not take into account the labor cost associated with changing bulbs, power savings, operating downtime, incandescent bulb inventory and ordering costs, and other significant factors.Since incandescent bulbs generate light by heating a filament, they also heat the lenses they illuminate. This causes discoloration and eventual melting of the control panel lenses.led high bay light generate much less heat than the incandescent bulbs they replace. Furthermore, heat is dissipated through the base of the LED lamp, keeping the lens cooler.
