Claim Text:
1. A lighting device comprising: a mounting surface having a central portion, wherein a plurality of through-holes are formed in the mounting surface; at least one light emitting element each comprising an LED chip and a translucent resin sealing the LED chip, the at least one light emitting element mounted in a central portion of the mounting surface such that the plurality of through-holes are closer to a peripheral edge of the mounting surface than all light emitting elements mounted on the mounting surface; a connector mounted on the mounting surface and mounted closer to the peripheral edge of the mounting surface than the plurality of through-holes, the connector configured to connect with a power supply disposed separately from the mounting surface; at least one lighting circuit component mounted on the mounting surface and mounted closer to the peripheral edge of the mounting surface than the all light emitting elements; and a reflector having a curved surface of a truncated cone shape, the reflector further having a single mounting opening and a single radiating opening at respective ends of the curved surface of the truncated cone shape, and the reflector mounted on the mounting surface via the through-holes, wherein the single mounting opening separates all light emitting elements from the connector and the at least one lighting circuit component, and wherein the at least one lighting circuit component is mounted on the mounting surface such that, in a direction parallel to the mounting surface, the at least one lighting circuit component is positioned closer to a center of the mounting surface than a circumferential edge of the radiating opening.
