• a light source unit comprising a plurality of light emitting elements disposed around a lens of the camera, wherein a light emitting direction of each of the light emitting elements is parallel to an image capturing direction of the lens;
• and
• a light adjustment unit disposed above the light source unit and comprising a plurality of secondary optical elements, wherein the secondary optical elements respectively correspond to each of light emitting elements, and a light emitted by each of the light emitting elements is deflected through the corresponding secondary optical element;
• wherein each of the secondary optical elements comprises a first ring-shaped prism and a second ring-shaped prism, a width of the second ring-shaped prism is greater than a width of the first ring-shaped prism, and the second ring-shaped prism surrounds an outer periphery of the first ring-shaped prism;
