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 method and apparatus for energy absorption and vibrational dampening when attached to a vertical or horizontal structure. According to a first preferred embodiment, the present invention includes a closed housing which may preferably include an internal, curved surface. According to a further preferred embodiment, the present invention may include at least one dampening weight or sphere which may preferably be disposed within the closed housing. According to a further preferred embodiment, the dampening sphere may include internal baffling such as particles having resistance to the flow of the particles within the closed housing.

In one or more embodiments, a luminaire includes a housing, a light source coupled with the housing, an optical sheet coupled with the housing, and a film stabilizer coupled with the housing. The optical sheet includes a first surface and an opposing second surface that are both disposed substantially horizontally when the luminaire is in an installed orientation. The first surface is disposed facing the light source, so that when the light source emits light, the light passes first through the first surface and subsequently through the second surface. The film stabilizer includes a third surface and an opposing fourth surface. The film stabilizer is disposed with the third surface adjacent to the second surface of the optical sheet, and provides mechanical support for the optical sheet.

A flashlight is protected from damage due to shock such as occurs when a flashlight is dropped, crushed or otherwise physically abused. A plastic molding can be attached to either the front or rear portion of a flashlight or to both portions to resiliently absorb shock forces. A series of thin fins projects axially outwardly from the molding to resiliently deform upon impact so as to absorb shock and distribute the shock around the ends of the flashlight and to reduce stress concentrations around the ends of the flashlight. A series of axially-extending and radially-extending ribs further protects the flashlight from axially and radially-directed shock forces and further absorb shock forces. An optional safety crush or clearance zone can be provided between each shock absorber and the flashlight.
