摘要： The present disclosure relates to a lighting device comprising light-emitting elements such as light-emitting diodes arranged on a substrate. The object to provide a lighting device comprising multiple light-emitting elements and light guides, wherein the thermal sensitivity of the lighting device is reduced in a particularly simple manner, is solved in that the lighting device comprises: a lens with a light entry side and a light exit side; light guides, each light guide being arranged in optical contact to at least one of the light-emitting elements and being configured to guide light emitted by the at least one of the light-emitting elements towards the light entry side of the lens; and a transparent stabilizer element being arranged in mechanical contact to the light exit side of the lens, wherein the transparent stabilizer element is configured to define the shape of the light exit side of the lens at least in regions. The invention further refers to a method for producing a lighting device.

摘要： Described is a CMOS power plane including interleaving contact areas, alternating Vled and Vcat contact areas, on at least two long sides of the μLED display area. By this way, Vled and cathode current are injected uniformly along the four sides of the μLED display panel. A large cathode current distribution ring on Vled and Vcat circuits is used to distribute the current along the four sides of the panel. The current distribution ring surrounds a pixel die area. An insulated area may be included on the cathode current redistribution ring adjacent one of the of μbumps.

摘要： A flexible lighting strip comprises a multitude of light-emitting diodes (LEDs) and is arranged to bend around at least two, preferably three, linear independent axes. The LEDs are arranged in at least two groups, wherein each group comprises at least two LEDs arranged in an electrical series connection. The groups are arranged in an electrical parallel connection to an anode and cathode track. The groups are arranged in a longitudinal arrangement such that a last LED of a first group is arranged next to the first LED of a second group, and are mechanically coupled via an electrically isolated coupling structure such that a stiffness of the flexible lighting strip between the last LED of the first group and the first LED of the second group is matched to a mechanical stiffness between neighboring LEDs comprised by one of the first or second.
