摘要:
A DC/DC converter 1 is configured to allow separation of a primary side constitution unit 3 and a secondary side constitution unit 4 of a transformer 2. A secondary side switching element FET 2 is provided in the secondary side constitution unit 4, and controls power supply to a load 12 by intermitting an output of a secondary winding L2. The primary side constitution unit 3 detects an electrical behavior of the primary side generated by the intermittent operation of the secondary side, and controls the power supplied from the primary winding L1 to the secondary winding L2 by operating the intermittent operation of the primary side switching element FET 1 such that a cycle or duty of the intermittent operation of the secondary side falls within a predetermined range.

An LED lighting device 1 lights LED blocks 4a and 4b which correspond to a plurality of functions of an illuminator such as headlights and are connected in series. The LED blocks 4a and 4b are connected in series with a current converting unit 5. While the LED blocks 4a and 4b are supplied with a current Ia from a single DC/DC converter unit 3, the LED block 4b is supplied with a current Ib that passes through conversion by the current converting unit 5 and that differs from the current Ia the DC/DC converter unit 3 outputs. Thus, the LED blocks 4a and 4b are each lit with appropriate brightness.

摘要:
A headlamp LED lighting apparatus, which lights an LED block 2 having a plurality of LEDs connected in series, samples the output voltage of the headlamp LED lighting apparatus, calculates the average voltage during every prescribed interval, and has a storage unit for storing the average voltage during every prescribed interval calculated. A control circuit 8 compares the voltage variation in the average voltage during every prescribed interval read out of the storage unit with a prescribed threshold, and decides an LED failure of the LED block 2 from a result of the comparison.

A task management apparatus includes a task information acquisition unit, an execution location position information acquisition unit, an execution candidate position information acquisition unit and a selection unit. The task information acquisition unit acquires task information for a task being executed by one of a plurality of execution candidates at one of a plurality of execution locations. The execution location position information acquisition unit acquires execution location position information for respective positions of the execution locations. The execution candidate position information acquisition unit acquires execution candidate position information on respective positions of the execution candidates. The selection unit selects one execution location and one execution candidate from the plurality of execution locations and the plurality of execution candidates, respectively, based on respective movement costs which are calculated from the acquired execution location position information and the acquired execution candidate position information.
