In accordance with an example embodiment, there is disclosed herein a LED PAPI () with condensation protection. The condensation protection may suitably comprise passive components, such as gaskets and seals () and a desiccant (), and/or active components, such as a defroster () and/or a heater ().

LED PAPI with condensation protection

A system and method for producing a flash of a desired intensity and duration utilizing devices of a lower intensity, such as light emitting diodes (LED's). The on period of the LED is lengthened so that the product of the LED's intensity and the on period is approximately equal to the product of the desired intensity and duration of the flash. A parameter for determining intensity, such as operating current or voltage, can be measured and the on period can be adjusted accordingly. The device can be turned on responsive to an external trigger signal, and a timer can be utilized to turn the device on if the external trigger signal is not received within a predetermined time.
