    Abstract: The disclosed systems and methods emphasize driving LEDs in series and in parallel with the same LED driver chip and a single inductor. For creating overlap, the systems and methods of LED color overlap disclosed herein take advantage of the fact that green and blue LEDs have the same voltage. Thus, green and blue LEDs can be driven in parallel as needed. LED suppliers can screen parts for sufficiently close voltage matching between green and blue LEDs. This is especially true when using green LED die based on a blue die with a green phosphor. Cyan may be produced by driving a green LED and a blue LED in parallel. White may produced by driving a green LED and a blue LED in parallel and a red LED in series with this green and blue parallel pair.

  • Patent number: 9894721
    Abstract: A lighting device includes a power converter, a second switching element and a microcomputer. The power converter is configured to convert DC power that is received from a power supply, and supply an output obtained by the conversion to a load. The second switching element is configured to short-circuit at least one LED of a plurality of LEDs, as part of the load. The microcomputer is configured to control the power converter, and control switching on/off of the second switching element. The microcomputer is configured to reduce an output current of the power converter, in a case where a power supply voltage of the battery is a reference voltage or less. A reduction amount of the output current in an on-state of the second switching element is lower than the reduction amount of the output current in an off-state of the second switching element.

  • Patent number: 9884582
    Abstract: A lighting device includes a thermal sensor, power converter circuits and a control circuit. The thermal sensor is configured to measure an internal temperature of a case. The power converter circuits are housed in the case and configured to be connected with different types of light sources, respectively. The control circuit is housed in the case and has priorities that are provided with respect to the different types of light sources according to their respective types. The control circuit is configured to, when the internal temperature is greater than a threshold, control the respective outputs of the power converter circuits so as to preferentially decrease an output for a light source corresponding to a first priority.
