Abstract
An LED panel assembly includes a circuit board having a plurality of LEDs. An LED seal louver is coupled over the circuit board. The LED seal louver includes a substrate and a pliable seal membrane. The substrate includes one or more substrate cavities. The pliable seal membrane is coupled with the substrate, and the pliable seal membrane includes a pliable material partially extending across the one or more substrate cavities. One or more LED passages extends through the pliable material adjacent to the substrate cavities. Each of the LED passages is sized and shaped to receive a single LED. Bulbs for one or more of the plurality of LEDs are correspondingly received within the LED passages, and the pliable material seals around each bulb with an interference fit. The bulbs are directly visible through the LED seal louver while the pliable seal membrane is sealed around the bulbs, and the circuit board is concealed by the LED seal louver and isolated from an environment exterior to the LED panel assembly.
