Abstract
A lighting apparatus includes a light source circuitry and an optical element. The light source circuitry has a light source baseplate, a plurality of light-emitting units arranged in an annular shape on the light source baseplate, and a driving circuitry located in an annular region surrounded by the light-emitting units on the light source baseplate. The optical element includes an annular optical accommodation region at an outer periphery and a driving accommodation region protruded from the optical accommodation region and is disposed in a region surrounded by the optical accommodation region. The optical accommodation region includes an optical accommodation groove which is facing the light-emitting units and configured to accommodate the light-emitting units. Light emitted by the light-emitting units is incident onto the optical accommodation groove and then exits upon being distributed; and the driving circuitry of the light source circuitry is correspondingly accommodated in the driving accommodation region.
