Disclosed is a fluorescent diffusion board for lighting including a first layer containing an inorganic material and a polycarbonate resin and a second layer formed on one surface of the first layer and configured to contain a polycarbonate resin and a fluorescent material.

A strip of a flexible plastic has a transparent cover surface which permits passage of light and an opposed bottom surface and sides which are opaque to passage of light. A series of spaced apart light emitting diodes are positioned on the top surface in electrical contact with a pair of spaced apart, generally parallel electrical wires running along the length of the top surface and individual electric bulbs are positioned on top of each light emitting diode. When electric current flows through the electrical wires, light is transmitted from each light emitting diode through each bulb and out in a unidirectional manner.

Lamp for the installation in an electric cabinet comprising at least one electric light source, and an optical device with at least two optical portions for transmitting and redirecting light emitted from said electric light source, wherein the redirection characteristics of one of the optical portions differs from the redirection characteristics of the other optical portion, and wherein the two optical portions are discrete from each other and integrally formed or connected.

Said lighting device is made up of lighting elements (L1, L2, . . . , L20) arranged on a mounting board (PS1, PS2, etc.). The one or more boards are arranged so as to supply light with a predetermined coverage.

The boards comprise a plugging system (C1, C2, C3, P1, P2, P3) for connecting said lighting elements. The mounting of such a device using a threaded rod 7 makes it possible to obtain easy maintenance of the device of the invention. This device can easily be used to form striplights.

Use: Lighting of car parks, meeting rooms.

An apparatus includes a coverlay layer having a void therein. A backing layer is disposed against a first side of the coverlay layer. A transmission layer is disposed against a second side of the coverlay layer opposite the first side such that a chamber is formed within the void between the transmission layer and the backing layer. The transmission layer includes a first area having a first level of light transmissivity and a second area having a second level of light transmissivity that is greater than the first level of light transmissivity. The transmission layer is oriented so that at least a portion of each of the first area and the second area overlaps the void. A light source is positioned in the chamber between the first area of the transmission layer and the backing layer.

An LED lighting device with an elongated lighting cavity formed by two opposed elongated curved or angled structures is disclosed. The opposed elongated curved or angled structures are positioned such that the concave surfaces or acute angles of the two opposed structures are juxtaposed with respect to each to form the elongated lighting cavity having elongated openings. The LED lighting device included arrays of LED light engines attached to one or more surfaces of one or more of the two opposed elongated structures within the lighting cavity to emit light from the elongated openings. In accordance with the embodiments of the invention the relative positions of the opposed elongated curved or angled structures are adjustable to change the lighting profile emitted from the elongated openings.

The present invention relates to a lighting device (1, 2, 5, 6) comprising a hollow and translucent envelope (12, 22, 52) connected to a base (13, 23, 53); a light mixing element (10, 20, 30, 50, 60) arranged within the envelope (12, 22, 52); and at least one light emitting diode (11, 21, 31, 51) arranged within the envelope (12, 22, 52), arranged to emit light into the light mixing element (10, 20, 30, 50, 60) and arranged in thermal contact with the light mixing element (10, 20, 30, 50, 60). The light mixing element (10, 20, 30, 50, 60) comprises a thermally conductive and translucent ceramic material. The light emitted from the light emitting diode (11, 21, 31, 51) is mixed within the light mixing element (10, 20, 30, 50, 60), distributed from the light mixing element (10, 20, 30, 50, 60) through the thermally conductive and translucent ceramic material, and transmitted through the translucent envelope (12, 22, 52). The present invention also relates to a luminaire comprising such a lighting device (1, 2, 5, 6).
