Runway-embedded flash lighting device

1. A runway-embedded flash lighting device comprising:

a body configured to be embedded in a runway;

a ceiling member disposed in an upper opening of the body and configured to be exposed to a runway surface when the body is embedded in the runway, the ceiling member comprising an upper ceiling portion and a lower ceiling portion, and at least a first flash emission window and a second flash emission window, the upper ceiling portion being disposed on a rear side relative to an emission direction of at least one of the at least first flash emission window and second flash emission window, and the lower ceiling portion being disposed on an emission direction side of at least one of the at least first flash emission window and second flash emission window;

a reinforcing plate member disposed on an outer surface of the lower ceiling portion of the ceiling member in a state of standing upright in a vertical direction with respect to the outer surface of the lower ceiling portion;

first and second light guide members, respectively being divided by the reinforcing plate member, the first light guide member being disposed in the first flash emission window, and the second light guide member being disposed in the second flash emission window; and

an LED flash light source disposed in the body, configured to emit a flash toward the first and second light guide members, and comprising a substrate, LEDs, and a lens member, the LEDs being mounted in a matrix in the substrate, the lens member being disposed above the LEDs and configured to produce a uniform illuminance distribution

the light guide member is configured to allow the flash emitted from the LED flash light source to be emitted from the first and second flash emission windows to outside the runway-embedded flash lighting device.

2. The runway-embedded flash lighting device according to claim 1 , wherein

the body and the ceiling member are integrally molded as an integrally molded product.
