A base carrier () for an illumination device (L; L; L), comprising a printed circuit board () having at least one first plug-in connection element () for mechanically securing and electrically coupling a light source carrier () to the printed circuit board ().

Base carrier, light source carrier and system comprising a base carrier and a light source carrier

A mounting arrangement for a light source (L) having associated a Printed Circuit Board, wherein said mounting arrangement includes: a housing (H) with an exit opening for light from the source (L), a reflector (R) to reflect light from the source (L) towards the opening, an at least partly transparent cover () to close the opening of the housing (H). The cover () includes a set of retaining elements (A) for retaining the cover () to the housing (H), and a set of holding elements (B) for holding the associated Printed Circuit Board (D) within the housing (H). Such configuration is capable of exerting a pressure on the reflector (R) when the cover () is coupled to the housing (H), and wherein the reflector (R) in turn urges the light source (L) against the housing (H), providing thus thermal coupling between the light source (L) and the housing (H).

Mounting arrangement for lighting devices, corresponding lighting devices and method

Connecting a first () and a second () printed circuit board or PCB carrying a LED lighting source () and the associated drive circuitry involves providing board connection pads () at said first () and second () PCBs, and arranging a flex PCB () in a bridge-like fashion between the first () and second () PCBs. The flex PCB () has connection pads () for bonding with the board connection pads () of the PCBs (). The connection pads () in the flex PCB () arranged in a bridge-like fashion between the first () and second () PCBs are bonded with the connection pads () of the first () and second () PCBs, so that the first () and second () PCBs are connected.

Method of connecting printed circuit boards and corresponding arrangement

An illumination unit comprising an LED light source is disclosed, which has a first optical element disposed downstream of the LED light source in an emission direction, an electronic control unit, and a second optical element disposed downstream of the first optical element. The LED light source, the first optical element and the electronic control unit are arranged in a common housing, and the housing is covered by the second optical element.

Illumination unit comprising an LED light source

An LED module for illumination systems is provided that can be installed in and connected to an illumination system in a simple way both electrically and mechanically, and that ensures the greatest possible flexibility with reference to its possible uses. The LED module has a plurality of light-emitting diodes () arranged on a carrier plate (), the carrier plate () being provided with at least one electrical connecting device () for electrically connecting the LED module, and with a fastening device () for fastening the LED module in an illumination system.

Led module for illumination systems

A mounting structure for LED lighting sources, includes a support body having attached on one side thereof a circuit board for mounting the LED lighting sources. The circuit board is preferably a printed-circuit board with conductive traces to feed electrical power to the LED lighting sources. The support body is in the form of an elongated bar or a box with a linear, round, square, hexagonal or octagonal shape. The support body is a drawn or molded body of a lightweight material and preferably exhibits good heat transfer properties. The support body includes a back side for mounting the structure on a supporting surface, such back side possibly having associated a heat dissipation fixture. Additionally, the support body may have free space inside and/or be at least partially apertured to permit cooling air flow for a driver circuit for driving the LED lighting source.

Mounting structure for LED lighting systems

A LED module having a plurality of LEDs, comprising mixed-light LEDs and additional LEDs, wherein each of the additional LEDs () has a plurality of LED chips () having different emission wavelengths, which, in each instance, are arranged in a common housing.

LED module

Method for defining the color group of an LED which emits mixed-color, in particular white, light. The CIE color space is divided by means of a network with two sets of intersecting network lines, one set being provided by a set of Judd straight lines and the other set by the line for the color loci of a Planckian radiator and also the associated lines of constant threshold value deviation, so that the network has a plurality of network cells bounded by network lines. The color locus of the LED is determined, and the network cell is determined in which the color locus of the LED is located. The LED is assigned to the color group of the network cell.

Method for defining the color group of an LED and LED module

LED module for generating white light having a plurality of white-light LEDs including at least one LED with a central wavelength of between 495 nm and 507 nm, at least one LED with a central wavelength of between 511 nm and 529 nm, at least one LED with a central wavelength of between 586 nm and 602 nm, and at least one LED with a central wavelength of between 618 nm and 630 nm.
