Fill light and electronic device

An electronic device, comprising:

• a fill light, comprising:
• a first reflector having a first reflection surface;
• a second reflector having a second reflection surface disposed opposite to the second reflection surface of the first reflector;
• a light-transmitting ring surrounding the first reflector;
• and
• a light-emitting light source, wherein a light-emitting side of the light-emitting light source faces the first reflection surface, light emitted by the light-emitting light source is emitted from the light-transmitting ring after being reflected by the first reflection surface and the second reflection surface,
• wherein the first reflector and the light-transmitting ring are located on a same side of the second reflector,
• the first reflection surface, the second reflection surface, and the light-transmitting ring are all rotationally symmetrical about a central optical axis of the light-emitting light source, and
• the first reflection surface comprises a first concave region, wherein:
• a distance between any point on the first concave region and the central optical axis of the light-emitting light source is a first distance,
• a distance between the any point on the first concave region and a plane on which the light-emitting light source is located is a second distance,
• the first distance is positively correlated with the second distance, and
• the first concave region is formed by rotating a first curve around the central optical axis of the light-emitting light source as a rotation axis, the first curve being a Bezier curve.
