Optical assembly with swing-adjustable lens and lighting fixture incorporating the same

An optical assembly with a swing-adjustable lens, comprising:

• a spherical cage base (1),
• a lens support (2),
• an optical lens (3), and
• an LED light source (4), wherein a spherical cage cavity (11) is formed in the spherical cage base (1), wherein the LED light source (4) is fixedly arranged in the spherical cage cavity (11), wherein the lens support (2) is provided with a hollow spherical head housing (21), wherein the optical lens (3) is arranged in an inner cavity of the spherical head housing (21), wherein a light outlet of the optical lens (3) is fixedly connected to the lens support (2), and wherein the spherical head housing (21) is rotatably arranged in the spherical cage cavity (11), so that the light inlet of the optical lens (3) and the LED light source (4) are arranged in a paired manner,
• wherein a limiting ring (22) is arranged in a lower opening of the lens support (2), wherein a skirt ring (31) is arranged at a light outlet of the optical lens (3), wherein a plurality of limiting fasteners (23) are arranged on a side wall of the lens support (2), and wherein the limiting fastener (23) interacts with the limiting ring (22) to fasten and connect the skirt ring (31).
