The introduction of the LED approach lighting systems brings energy saving opportunities, answers to the requirements Energy Act of 2007 and brings challenges to the Enhanced Vision Systems depending upon the Excess energy of the incandescent sources for an infrared signature to identify the runway approach.Patriot Taxiway industries studied the feasibility of integrating IR emitters into an LED based lighting fixture. This included reviewing the complex requirements of making an LED fixture with Infrared (IR) sources into existing MALSR systems. Patriot evaluated the IR requirements of the Enhanced Vision systems and the PRD-LED-0001 requirements to provide detailed IR design feedback for the customer to use for evaluation.
The current MALSR and integrating new LEDIR fixture were presented in study. Issues in integrating fixture into the MALSR were identified and addressed.
