Optics For Emergency Lighting and Visual Alarm Devices
Polymer Optics free form optic technology is particularly suited for applications requiring wide area illumination. Emergency lighting and Visual Alarm Devices are areas where light from an LED has to be distributed over a wide area efficiently. It should be remembered that not only is light wasted if it is sent outside the specified area but also if there is more light in any one area than the specification calls for.
Producing just the illumination level required by the regulations over a defined area is where our free form optics excel. Using them reduces overall system costs because the more efficient the optic is, the less optical output is required from the LED. Reducing the lumens required from the LED allows a cheaper LED to be installed and reduces the electrical current needed to drive them with the consequential reduction in the backup battery size.
