Abstract
A surface-mounted LED including a base having heat conductivity, an insulative wiring board fixed to the base and including a conductive pattern and a mounting hole, a light emitting element chip mounted on a mounting area exposed by the mounting hole of the wiring board, and a reflective frame having heat conductivity and fixed to the base and thermally coupled therewith, to surround the light emitting element chip, heat generation from the light emitting element chip being released through both the base and the reflective frame, or either one thereof.
Claims10
A surface-mounted LED, comprising:
- a base having heat conductivity;
- an insulative wiring board fixed to said base and including conductive patterns and a mounting hole;
- a light emitting element chip mounted on the base directly inside the mounting hole of the wiring board;
- and
- a sealing member for sealing the light emitting element chip;
- and
- a reflective frame having heat conductivity and fixed to the base within the mounting hole of the wiring board to surround the sealing member,
- wherein the reflective frame is disposed separately from the sealing member, and
- wherein heat generation from the light emitting element chip is released through both the base and the reflective frame.
