    摘要： A balance circuit includes a reference circuit configured to generate current through strings of light emitting diodes (LEDs). The reference circuit includes a first string of LEDs in series coupled to a collector node of a first transistor. A base drive current resistor is connected between the collector node and a base node of the first transistor. A base emitter resistor is connected between the base node and an emitter of the first transistor such that a reference voltage is generated on the base node during operation. Another stage receives the reference voltage to generate a tracking current through a second transistor and a second string of LEDs connected to a base of the second transistor, wherein a current through the first string of LEDs is uniformly tracked by the tracking current through the second string of LEDs.

    摘要： A color correction device includes a computation engine including a processor and a memory coupled to the processor. The computation engine is configured to receive reference color data. A software application stored in the memory and configured to compute adjustment values needed to achieve the reference color data from a target color. An output configured to output color corrected signals to light emitting diodes (LEDs) to achieve a reference color associated with the reference color data from the target color of the LEDs.

    摘要： A lighting device includes a substrate, an electrical circuit operably coupled to the substrate, a connector block operably coupled to the substrate and in electrical communication with the electrical circuit, and a casing disposed over the substrate, the electrical circuit, and the connector block. A portion of the casing defines a contact surface. The contact surface and a portion of the substrate define a cavity therebetween. A portion of the contact surface of the casing abuts a corresponding portion of the connector block to provide mechanical support to a joint formed between a portion of connector block and a portion of the substrate.

    摘要： A balance circuit includes a node on which a reference voltage is generated to control current through a first component string and a first resistor connected to the first component string. A stage receives the reference voltage to generate a tracking current through a second component string and a second resistor connected to the second component string, wherein a current through the first component string is uniformly tracked by the tracking current through the second component string.
