Abstract
A luminaire includes a frame member, an inner panel, light emitting diodes (LEDs), an information carrier, and two outer panels. The inner panel has two surfaces and edges that join the two surfaces such that the inner panel is able to reflect light substantially perpendicularly to its two surfaces. The LEDs are arranged along at least one edge of the inner panel and are detachably attached to the frame member. The information carrier is associated with at least one surface of the inner panel. The two outer panels are associated with the two surfaces of the inner panel. To protect the luminaire against environmental influences and at the same time to maintain the optical appearance of the luminaire, the inner panel and the two outer panels are held by the frame member for water-tight encapsulation.
Claims27
A luminaire comprising:
- a frame member;
- an inner panel having two surfaces and edges that join the surfaces, the inner panel being able to reflect light substantially perpendicularly to its surfaces;
- light emitting diodes (LEDs) arranged along at least one edge of the inner panel and detachably attached to the frame member;
- an information carrier associated with at least one surface of the inner panel;
- and
- two outer panels associated with the two surfaces of the inner panel;
- wherein:
- the inner panel and two outer panels are held by the frame member for water-tight encapsulation,
- the frame member includes a U-shaped carrier having U-legs, and
- the LEDs are arranged between the U-legs such that, when the inner panel is held by the frame member, the U-legs partially project over the inner panel.
A luminaire comprising:
- a frame member having U-legs that extend inwardly from the frame member, each U-leg including an inner surface and an outer surface;
- an inner panel having two surfaces and edges that join the surfaces, the inner panel being able to reflect light substantially perpendicularly to its surfaces and the inner panel being held between the inner surfaces of the U-legs;
- light emitting diodes arranged along at least one edge of the inner panel;
- an information carrier associated with at least one surface of the inner panel;
- and
- two outer panels associated with the two surfaces of the inner panel, each outer panel contacting an outer surface of a U-leg,
- wherein the LEDs are arranged between the U-legs such that, when the inner panel is held by the frame member, the U-legs partially project over the inner panel.
A method of making a luminaire, the method comprising:
- arranging lights along at least one edge of an inner panel;
- detachably attaching the lights to a frame member that includes a U-shaped carrier having U-legs;
- associating an information carrier with at least one surface of the inner panel;
- and
- associating two outer panels with two surfaces of the inner panel including heating inner surfaces of the outer panels that face the inner panel until the inner surfaces of the outer panels are softened such that the outer panels are welded to the inner panel for water-tight encapsulation,
- wherein arranging the lights comprises arranging the lights between the U-legs such that, when the inner panel is held by the frame member, the U-legs partially project over the inner panel.
