Abstract: Disclosed is an illuminating system of flexible shape and comprising at least one LED disposed on a flexible carrier material, an optic being provided that permits uniform, directed and/or glare-free light emission.

Abstract: Production of a photovoltaic element, more particularly of a solar cell. In this case, an additional silicon dioxide layer is used, which is produced by UV irradiation with a wavelength of less than 200 nm and can improve the interface properties on the silicon and can help to reduce disturbances known by the expression “background plating”.

Abstract: The present invention relates to a light source unit having at least one LED sub light source unit. Each LED sub light source unit includes three types of LEDs: phosphor converted green LED, orange-red LED with a wavelength of 614 nm-622 nm, and blue LED with a wavelength of 460 nm-476 nm. Light generated by the three types of LEDs is mixed to generate white light.

Abstract: A lighting system may include a housing for a lighting module and at least one profiled element which can be coupled to the housing and protrudes from the housing when coupled to the housing. The housing has an external surface with a plurality of channels and comprises a plurality of seats. The profiled element may have a first engagement formation insertable into one of the channels of the housing and a second engagement formation insertable into one of the seats of the housing when the first engagement formation is inserted in the channel. Blocking means movable into a first and into a second operative position, may be.

Abstract: The present invention relates to an electronic assembly which includes a printed circuit board and at least two I-type inductors arranged on the printed circuit board, the I-type inductor include an I-type magnetic pillar, respectively, wherein the magnetic pillars of the at least two I-type inductors are arranged in such a manner that a first end surfaces of the magnetic pillars are non-coplanar with each other and/or the second end surfaces of the magnetic pillars are non-coplanar with each other. In addition, the present invention further relates to an LED retrofit lamp having such electronic assembly.

Abstract: A circuit for driving a plurality of light sources via a current generator, wherein the light sources are grouped into a plurality of light source sets wherein the driver circuit comprises a plurality of inductive elements, a plurality of switches adapted to selectively connect each light source set in series with one of the inductive elements, and a control circuit configured for driving the switches, so that during a first operation time interval, each light source set is connected in series with a respective first inductive element, and during a second operation time interval, each light source set is connected in series with a respective second inductive element, wherein the respective second inductive element is separate from the respective first inductive element.

Abstract: A reflector for light radiation sources, the reflector taking the form, for example, of a cup centered around a main axis with a bottom opening for a source of light radiation, the reflector including a cup-shaped base portion extending from the bottom opening to an outer rim, and an annular portion surrounding the outer rim. The annular portion may be telescopically coupled to the base portion and may be moveable with respect to the base portion along the main axis in order to vary the length over which the annular portion extends along the main axis with respect to the outer rim of the base portion.

Abstract: A device for mounting lighting sources on a substrate includes a mounting frame provided with fixing formations for fixing on the substrate, the mounting frame defining a cavity for receiving the lighting source which rests on the substrate. A locking member may be provided which can be positioned in the cavity of the mounting frame to urge said lighting source toward the substrate. At least one of the mounting frame and the locking member may include at least one retaining formation for the lighting source, including one or more pins extending into corresponding openings in the lighting source, and/or one or more elastic fins extending from the mounting frame to elastically contact the lighting source.

Abstract: A device for mounting planar lighting sources having a light emitting surface on a substrate includes a frame provided with fixing formations for fixing the frame on the substrate with the planar lighting source sandwiched between the frame and the substrate. The frame has an opening to surround the light emitting surface of said lighting source and is provided with elastic formations to elastically urge the lighting source toward the substrate. The fixing formations include at least one resilient formation to resiliently urge the frame toward the substrate.
