Abstract
The present disclosure discloses a light source module and a lighting device. The light source module includes an annular light source substrate, which is enclosed to form a housing region, and the light source module further includes a plurality of light emitting units disposed on a surface of the light source substrate, a driving power component disposed in the housing region and electrically connected with the light source substrate, and a light distribution element. The light distribution element includes an annular optical portion covering the light source substrate, a drive housing portion housing the driving power component and disposed in the housing region, and at least two connection portions connecting the drive housing portion to the optical portion. The at least two connection portions divide the housing region into at least two separated spaces.
