A debris shield for preventing debris from entering a light fixture device during a construction process while allowing the light fixture device to be used to illuminate an area where the construction process is taking place includes a transparent or translucent body and at least one projection arranged on or associated with the body for removably retaining the debris shield to the light fixture device. The debris shield can be removed from the trim ring after the construction process is completed by puncturing a closure covering an opening in the body of the debris shield and grasping the opening to pull the debris shield from the trim ring. Alternatively, the debris shield can be removed from the trim ring after the construction process is completed by grasping a pull tab on the body of the debris shield and using the pull tab to pull the debris shield from the trim ring.

A decorative lighting apparatus including a first light source generating a first light having a first color, a second light source generating a second light having a second color, a first stationary optical element having a diffraction grating and disposed in a first path of the first light generated by the first light source, a second stationary optical element having a diffraction grating and disposed in a second path of the second light generated by the first light source, and a motion assembly. The motion assembly including a first articulating optical element having a diffraction grating and disposed in a first path of the first light being generated by the first light source, a second articulating optical element having a diffraction grating and disposed in a second path of the second light being generated by the second light source, and at least one motor coupled to the first and second articulating element such that a movement generated by the motor drives the first and second articulating optical elements. The motion assembly being configured such that the movement driving the articulating optical elements by the motor causes the first light and the second light to move across a surface onto which the first light and the second light are being projected in a predetermined pattern.

The luggage lighting system includes a piece of luggage and a lighting module coupled to the luggage. In some embodiments, the lighting module is a fiber-optic lighting module. The luggage includes an outer surface, and the lighting module includes a light diffuser coupled to the outer surface. In some embodiments, the light diffuser is a fiber-optic light diffuser. The lighting module also includes a light source, such as a laser or a light emitting diode (LED). When the light source is powered on, the output light is directed through the light diffuser. The light diffuser is configured to output single or multiple colors of light, easily observed by someone looking at the luggage. The luggage lighting system is particularly useful for identifying one's luggage from surrounding pieces of luggage lacking the luggage lighting system.

A luminaire includes a light emitting diode module, a driver housing, and a hollow connector that connects the driver housing and the light emitting diode module. The driver housing includes a rotatable cap and a driver that provides power to the light emitting diode module. The rotatable cap permits rotation of the hollow connector and the light emitting diode module in order to direct the light from the light emitting diode module in a desired direction. The light emitting diode module includes a plurality of optics wherein each optic covers at least one light emitting diode and at least one vent adjacent to each optic.

Provided is a flexible LED light source panel including: a flexible LED module in which a plurality of LEDs is disposed in an array form on a flexible circuit board; a protective sheet stacked on the flexible LED module and diffusing light from the LEDs; a heat conduction sheet disposed under the flexible LED module; a heat radiation sheet disposed under the heat conduction sheet, made of fireproof fiber, and coated with a carbon nano tube molecule having a grid or vertical structure; and a light source guide having a quadrilateral shape.

A multilayered illuminated laminate system including a light source positioned proximate to an edge of a light panel that includes a series of reflective paint in the shape of diamonds of increasing size is provided. The system further includes a diffuser sheet of sufficient opacity that it obscures the diamond pattern on the bottom surface of the light panel and a reinforced panel formed from fiberglass that bestows the system with scratch, abrasion, impact, and chemical resistance to meet or exceed current regulatory requirements. The light source is positioned within a clamp mount that contains the light panel, diffuser, and reinforced panel in frictional engagement without the need for an adhesive. A graphic can be positioned between the diffuser sheet and the reinforced panel to increase the aesthetic appearance of the system exterior surface, as well as moderate the intensity of the light it emits.

Disclosed is an aircraft provided with a light signaling system including at least one light-emitting device at the tip of each wing and at least one light-emitting device at the tip of the tail. Each light-emitting device at the wingtip can be arranged in a recess formed in the profile of the wing and include a covering At least one light source and a protective glass can be arranged on the recess so that the outer surface matches the shape of the wing. The inner surface of the protective glass can be provided with at least one local variation in thickness so as to increase the angular aperture of each wingtip light-emitting device in order to ensure the overlap between the light-emitting devices at the wingtip and the light emitted by the light-emitting device on the tail.
