摘要： A lighting device comprises at least one LED element for emitting light into an emission direction. A bendable light guide is arranged to guide light emitted from the LED element. The bendable light guide comprises at least a first portion formed of an elastic, light transmitting light guide material covering at least the emission direction of the LED element, and a second portion formed of an elastic, light transmitting light guide material. In order to be able to function under varying environmental conditions, the second portion is arranged spaced from the first portion in the emission direction by a separation space.

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： The invention relates to a lighting arrangement with at least one LED lighting element (15) arranged on a support member (12). An optical element (16) is arranged spaced from the LED lighting element (15) in a first direction O. A holder (14) is provided to hold the optical element (16) in a position relative to the LED lighting element (15). The holder (14) comprises at least a first holding portion (24a) extending from the support member (12) into the first direction O and a second holding portion (24b) connected to the optical element (16). The second holding portion (24b) is arranged such that at least a part extends into the first direction O. The second holding portion (26b) is spaced from the first holding portion (24a) in a direction traverse to the first direction O. In the case of distortions due to temperature changes and a mismatch of the coefficient of thermal expansion, the lighting arrangement minimizes variations in the displacement of the optical element (16) relative to the LED lighting element (15).

摘要： Support structures and lighting systems including the support structure and a lighting device are described. A support structure includes an inner housing portion, an outer housing portion and connection members. The inner housing portion is transparent and has at least one portion shaped to conform to the lighting device. The outer housing portion includes at least a bottom wall, a first side wall and a second side wall, each having reflective inner surfaces, to form a container. The connection members are transparent and mechanically connected between the inner housing portion and the outer housing portion to support the inner housing portion and divide a region of the container between the inner housing portion and the outer housing portion into first cavities, each enclosed by at least one of the bottom wall, the first side wall or the second side wall and at least one of the connection members.

摘要： A method for producing a flexible lighting strip comprising multitude of functional elements, which are light-emitting diodes, comprise light-emitting diodes, or are interposers with light-emitting diodes. The functional elements are in at least two groups, each comprising at least two functional elements in electrical series connection. The groups are in an electrical circuit having at least an anode and a cathode track as outer lines. The functional elements are in an electrical parallel connection to the anode and cathode tracks. The groups are in a longitudinal arrangement so a first group's last functional element is next to a second group's first functional element. Each of the outer lines has a wire line having substantially circular wires that are bent building zones capable of receiving compressive and tensile stress. The electrical circuit provides a third wire line having a substantially circular wire as a center line arranged between the outer lines.
