Illumination angle adjustment structure and luminaire with adjustable illumination angle

An illumination angle adjustment structure for assembling an optical module on a lamp housing, enabling light emitted from the light source module to enter the optical module, wherein the illumination angle adjustment structure comprises a point contact member;

• the point contact member is disposed around a peripheral wall of the optical module and connected to the optical module;
• the point contact member and the optical module are accommodated in the lamp housing;
• the point contact member abuts against an inner wall of the lamp housing via point contact;
• and a side of the point contact member away from the optical module is rollably connected to the inner wall of the lamp housing in any direction, enabling the optical module to rotate relative to the lamp housing to alter an exit direction of the light passing through the optical module;
• wherein the point contact member comprises at least three rolling components, the three rolling components being arranged around the peripheral wall of the optical module;
• each rolling component is connected to the optical module, accommodated in the lamp housing, and abuts against the inner wall of the lamp housing via point contact;
• and sides of the three rolling components away from the optical module are independently rollably connected to the inner wall of the lamp housing in any direction, enabling the optical module to rotate relative to the lamp housing;
• wherein each rolling component comprises a carrier and a spherical roller;
• the carrier is configured to connect to the optical module;
• the spherical roller is rollably connected to a side of the carrier away from the optical module;
• and the side of the spherical roller away from the carrier abuts against the inner wall of the lamp housing via point contact;
• the carrier of each rolling component is independently rollably connected to the inner wall of the lamp housing in any direction via the spherical roller;
• wherein each rolling component comprises a telescoping member;
• one end of the telescoping member is connected to a side of the carrier proximate to the optical module, and the other end of the telescoping member is connected to a side of the optical module proximate to the carrier;
• and the telescoping member is configured to generate an elastic force to press the spherical roller against the inner wall of the lamp housing;
• wherein each rolling component comprises a guiding member connected to the peripheral wall of the optical module;
• the side of the spherical roller away from the carrier at least partially protrudes beyond the guiding member;
• the carrier is slidably coupled to the guiding member;
• an end of the telescoping member proximate to the optical module is connected to the optical module via the guiding member;
• and the guiding member is configured to permit telescopic motion of the telescoping member, enabling the spherical roller to slide relative to the guiding member toward or away from the optical module.
