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.
摘要:
A LED module having a plurality of LEDs, comprising mixed-light LEDs and additional LEDs, wherein each of the additional LEDs (2) has a plurality of LED chips (6, 7, 8) having different emission wavelengths, which, in each instance, are arranged in a common housing.
摘要:
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.

A method for managing drilling rods, drilling tools, well—tubing and the like for ground drilling, particularly for exploring deposits of fossil fuels or geothermal reservoirs. An electronic data processing system stores information regarding the inventory and the present storage location of parts to be inserted into the well, such as drilling rods, drilling pipes, lining tubing, intermediate parts, drill bits, and the like, with additional information being saved in the computing system regarding the installation position and/or installation sequence of all parts inserted into the well so that the computing system can indicate to a user when and from where which part shall be fed to the well hole—supply system and/or to what location which part shall be returned to for storage when it must be removed from the well, and/or the computing system controls an automatic storage, supply, and restorage device.
摘要:
Connecting a first (12) and a second (14) printed circuit board or PCB carrying a LED lighting source (10) and the associated drive circuitry involves providing board connection pads (12a, 14a) at said first (12) and second (14) PCBs, and arranging a flex PCB (16) in a bridge-like fashion between the first (12) and second (14) PCBs. The flex PCB (16) has connection pads (16a) for bonding with the board connection pads (12a, 14a) of the PCBs (12, 14). The connection pads (16a) in the flex PCB (16) arranged in a bridge-like fashion between the first (12) and second (14) PCBs are bonded with the connection pads (12a, 14a) of the first (12) and second (14) PCBs, so that the first (12) and second (14) PCBs are connected.

摘要:
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 (1) to close the opening of the housing (H). The cover (1) includes a set of retaining elements (12A) for retaining the cover (1) to the housing (H), and a set of holding elements (12B) 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 (1) 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).
