A runway-embedded flash lighting device, includes a body configured to be embedded in a runway; a ceiling member including a flash emission window and 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; a light guide member disposed in the flash emission window; an LED flash light source disposed inside the body and configured to emit a flash toward the light guide member; and a heat conducting member, wherein the light guide is configured to allow the flash emitted from the LED flash light source to be emitted from the flash emission window, the heat conducting member is disposed inside the body and includes a first part in contact with the LED flash light source, and a second part in contact with the ceiling member.

The present invention provides an attachment device for an aircraft landing guidance flashing light and an aircraft landing guidance flashing device that do not require adjustment of the angle of the flashing light at the time of attaching an aircraft landing guidance flashing light to the attachment device for an aircraft landing guidance flashing light. An attachment device for an aircraft landing guidance flashing light includes a pair of attachment arms 11; and a light emitting portion fixing plate 12. The light emitting portion fixing plate 12 detachably fixes an aircraft landing guidance flashing light. The light emitting portion fixing plate 12 is supported by the pair of attachment arms 11 such that an angle of the aircraft landing guidance flashing light is at a predetermined angle in a state where the aircraft landing guidance flashing light is fixed to the light emitting portion fixing plate.

A runway-embedded flash lighting device includes, a body configured for embedding in a runway, a ceiling member with a flash emission window, a bottom cover member, a light guide member disposed in the flash emission window, and two or more flash emission windows. The light guide member is disposed in each of the flash emission windows and an inner surface of the ceiling member is provided with a site to be disposed with a LED flash light source below the flash emission window. The LED flash light source includes, an LED module, a frame-shaped attaching plate; and a lens member. The lens member is attached to a hollow portion in a frame of the frame-shaped attaching plate, and is configured to allow an emission surface of the flash emitted from the LED module to have a uniform illuminance distribution.

The present invention provides a new LED flash light source that is light, has a long life, has high effective luminous intensity, can switch the luminous intensity, is low in power dissipation, and is excellent in impact resistance. An LED flash light source (10) for a runway-embedded flash lighting device includes: an LED module (11); a frame-shaped attaching plate (12); a lens member (13); and a shock-absorbing sheet. The lens member (13) is attached to a hollow portion in s frame of the frame-shaped attaching plate (12), the lens member (13) is a lens member (13) that allows an emission surface of flash emitted from the LED (11b) to have a uniform illuminance distribution, the shock-absorbing sheet includes a lower shock-absorbing sheet (14a) and an upper shock-absorbing sheet (14b), the lower shock-absorbing sheet (14a) is placed on the LED module (11), the frame-shaped attaching plate (12) to which the lens member (13) is attached is placed on the lower shock-absorbing sheet (14a), and the upper shock-absorbing sheet (14b) is placed on the frame-shaped attaching plate (12).

Devices, methods, and systems for securing a light assembly of an airfield light are described herein. One device includes a light assembly, a base, and a locking assembly configured to secure the light assembly to the base. The locking assembly includes a plunging mechanism configured to compress against a cover of the light assembly while the cover is being rotated relative to the base, and extend into an opening of the cover of the light assembly to secure the light assembly to the base.
