摘要： The size and cost of a lighting device can be reduced by monitoring a plurality of input states and changing an output using a common coil or common switch element. A powder converter receives a plurality of DC powers, which are received in different modes, have a common ground and substantially the same potential, and operates a plurality of loads. The power converter operates the loads according to input states of the plurality of DC powers and supplies the plurality of loads with power via at least a common switch element or a common coil. A first DC power is power supplied via a switch for turning on a passing beam of a vehicle. A second DC power is power supplied in tandem with an ignition of the vehicle. A first load is a vehicle headlight. A second load is a day time running light (DTRL) of the vehicle.

摘要： A transformer in this invention comprises substrates constructing a primary winding, substrates constructing the secondary winding, and a core member disposed around the substrates. The substrates defining the primary winding are provided with insertion holes for passing a middle leg portion of the core member, and patterned conductors having one turn. The transformer further comprises an interlayer connection member. The interlayer connection member is located inwardly of the patterned conductors of the substrates defining the primary winding. The interlayer connection member is located on the same side of the patterned conductors defining the primary winding. The interlayer connection member is configured to establish the electrical connection of the patterned conductors defining the primary winding.
