Abstract
A light source device includes a light source, a holder, and a lead board. The holder has a first face to hold the light source. The lead board has a first electrode connected to the light source through a solder, a second electrode to be connected to a circuit board, a first connector connected to the second electrode, and a second connector to connect the first electrode and the first connector. The first electrode and the first connector are exposed from the first face of the holder. The second connector is unable to be exposed from the first face of the holder.
Claims19
A light source device to be mounted on a circuit board, the light source device comprising:
- a light source;
- a holder having
- a first face to support the light source, the first face being flat, and
- a second face to be mounted on the circuit board, the second face crossing with the first face;
- and
- a single piece lead board mounted to the holder so as to electrically connect the circuit board and the light source, wherein
- the single piece lead board has
- a first electrode connected to the light source through a solder, the first electrode being exposed from the first face of the holder,
- a second electrode connected to the circuit board, the second electrode being exposed from the second face of the holder,
- a first connector connected to the second electrode, the first connector being exposed from the first face of the holder, and
- a second connector to connect the first electrode and the first connector, the second connector being unable to be exposed from the first face of the holder;
- wherein
- the single piece lead board is made of a single piece board-shaped member constructed to define the first electrode, the second electrode, the first connector and the second connector.
A light source device in combination with a circuit board, the combination comprising:
- a light source,
- a holder including a first face supporting the light source and a second face mounted to the circuit board, the second face crossing with the first face;
- a single piece lead board mounted to the holder, the single piece lead board electrically connecting the circuit board and the light source, the single piece lead board including a first electrode connected to the light source, a second electrode connected to the circuit board, a first connector connected directly to the second electrode, and a second connector connected directly to the first electrode;
- wherein
- the first connector extends directly between the second electrode and the second connector and is connected directly to the second connector;
- and
- the second connector extends directly between the first electrode and the first connector.
