A light projector intended to produce a directional flat light beam includes an elongate cylindrical lens and a linear light source parallel to the generatrix direction, extending over all or part of the length of the lens to emit light in the direction of the lens. The lens is designed to generate a principal flat light beam by concentrating the light in a predefined elevation angular sector around the horizontal generatrix direction. The light projector also includes a deflector having a rectangular plate shape positioned on the side opposite the light source. A signalling beacon including such a projector is also described.

Exemplary embodiments of the present disclosure are directed towards methods and apparatus for molding-in gaskets that serve as light blockers, within the grooves of a moving planar work material. The gaskets comprise of a hot melt adhesive material that is in a molten state above a particular temperature and gets solidified below a particular temperature. Another exemplary embodiment of the present disclosure is directed towards a planar work material having grooves that are filled with molded-in gaskets, wherein the gaskets are made up of a hot melt adhesive material. The gaskets made of the hot melt adhesive material bond securely with the panels because of inherent adhesive properties, and provide structural stability to the light panels. Another exemplary embodiment of the present disclosure is directed towards the use of a hot melt adhesive material as the molding material for molding-in gaskets within the grooves of a planar work material.

A lighting apparatus to be installed in an area adjacent to land is provided. The lighting apparatus includes a plurality of light sources disposed on a board and further includes a light shield. The light shield blocks a portion of light emitted from the light sources. The portion of light has a predetermined wavelength. The light shield is disposed on the board closer to the land than at least a light source disposed closest to the land among the light sources. The light shield has a shape which sends, to the land, first emission light included in the light emitted from the light sources. The shape avoids sending, to the land, second emission light included in the light emitted from the light sources. The first emission light passes through the light shield. The second emission light does not pass through the light shield.

The present disclosure relates to a refrigerator with an improved lighting structure. The refrigerator includes a main body in which a storage compartment is formed, a light source provided on an inner surface of the storage compartment to provide light, and a lighting cover provided to cover the light source, wherein the lighting cover includes a first opening formed to irradiate light in a direction perpendicular to the inner surface of the storage compartment, and a second opening formed to be inclined with respect to the inner surface so that light is irradiated to the front of the storage compartment.
