6. An LED lamp unit, comprising:
-
an LED lamp;
a protective component for an LED lighting circuit;
a resistor element;
a circuit section; and
a case part;
wherein said circuit section has a metal plate which is embedded in said case part with the metal plate partially exposed, an exposed part of said metal plate is formed with an LED connecting region to which said LED lamp is connected, a protective component connecting region to which said protective component for the LED lighting circuit is connected, and a first lead connecting region and a second lead connecting region to which leads (a first lead and a second lead) of said resistor element are respectively connected, said case part has a pair of arm portions formed at one end side of the LED lamp unit and including a first arm portion and a second arm portion, said first lead connecting region being exposed from a distal end part of said first arm portion, said second lead connecting region being exposed from a distal end part of said second arm portion, said first arm portion has a groove area into which a root of said first lead is inserted, a flat area which is parallel to said first lead connecting region and on which a middle part of said first lead is placed, and a guide area which is a wall face erected from said flat area and adapted to guide the middle part of said first lead, and said second arm portion has a groove area into which a root of said second lead is inserted, a flat area which is parallel to said second lead connecting region and on which a middle part of said second lead is placed, and a guide area which is a wall face erected from said flat area and adapted to guide the middle part of said second lead. - View Dependent Claims (7, 8, 9, 10, 11, 13, 14, 15)

12. A metal plate package for an LED lamp unit, comprising:
- a metal plate; and
a case part;
wherein said metal plate is embedded in said case part with the metal partially exposed;
an exposed part of said metal plate is formed with an LED connecting region to which said LED lamp is connected, and a first lead connecting region and a second lead connecting region to which leads (a first lead and a second lead) of said resistor element are respectively connected;
said case part has a pair of arm portions formed at one end side of the metal plate package and including a first arm portion and a second arm portion, said first lead connecting region being exposed from a distal end part of said first arm portion, and said second lead connecting region being exposed from a distal end part of said second arm portion;
said first arm portion has a groove area into which a root of said first lead is inserted, a flat area which is parallel to said first lead connecting region and on which a middle part of said first lead is placed, and a guide area which is a wall face erected from said flat area and adapted to guide the middle part of said first lead; and
said second arm portion has a groove area into which a root of said second lead is inserted, a flat area which is parallel to said second lead connecting region and on which a middle part of said second lead is placed, and a guide area which is a wall face erected from said flat area and adapted to guide the middle part of said second lead.
