A light fixture includes a light-emitting diode chip, a driver electronic, a first circuit board and a second circuit board, wherein the light-emitting diode chip is mounted on one of the two circuit boards and the driver electronic is mounted on the other one of the two circuit boards and a first conductive track of the first circuit board and a second conductive track of the second circuit board are connected electrically to one another with a spring contact.

Electrical connection of PCBs by clamp spring connector

A fastening element for fastening a light source substrate to a support. The fastening element is configured to be seated on the light source substrate, and includes at least one fastening portion for fastening to the support.

Fastening element, luminous module and luminous apparatus

An LED module may include at least one passage opening from a first side of the LED module to a mounting side of the LED module, located opposite the first side. The passage opening is formed in such a way that a screw for fixing the LED module to a mounting element can be inserted into the passage opening from the first side to the mounting side of the LED module, and with a film which, at least in part, is arranged in an adhesive manner on the first side of the LED module. The film has at least one structure which includes at least one piercing of the film in the area of the at least one passage opening of the LED module.

A lighting module, comprising a printed circuit board, which on the front side thereof, is populated by at least one light source as well as at least one light sensor; a hollow optical waveguide element, which laterally surrounds the at least one light source circumferentially; and a cover at least for the light sensor, arranged on the printed circuit board externally to the optical waveguide element, it being possible for a window to be located in the optical waveguide element to which window is connected a hollow light channel formed in and/or on the cover which leads to the light sensor.

Lighting module

A method for controlling the operation of an electronic converter (), comprising a power output () for providing a power supply signal () for a light source (L), wherein said light source (L) is coupled to an identification element () which identifies at least one control parameter of said light source (L), and a data line () for connection to said identification element (), wherein said method comprises: detecting () the value of the voltage on said data line; (), comparing () the detected value of said voltage with at least a first and a second range of values; (), and a) determining said at least one control parameter as a function of the detected voltage () on said data line (), if the detected voltage is within the first range (), or b) communicating () with said identification element () by means of a digital communication protocol in order to receive said at least one control parameter from said identification element () if the detected voltage is within the second range ().

Method for controlling the operation of an electronic converter, and a corresponding electronic converter, lighting system and software product

A lighting device, having at least one light outlet opening and at least two different fixing interfaces for the optional fixing of a respective attachment element optically upstream of the at least one light outlet opening.

Lighting device and attachment element for fixing to the lighting device

A substrate with banks having end channels is provided to advantageously allow excess fluid collecting on one part of the substrate to flow to another part of the substrate. An excess of fluid collecting in a particular area of the substrate may flow to an area of the substrate where it would not interfere with the manufacturing process. The end channels may be modified with wave breakers that act as buffers to redirect excess fluid and/or with capillary-force homogeneity enhancers that pull excess fluid away from other parts of the substrate. The end channels may also contain line-end reservoirs that provide additional room for excess fluid to collect.
