The present disclosure a light lamp including an upper body, a lower body arranged opposite to the upper body, and a lighting unit configured to light the lighting lamp. The lighting unit includes at least one first lighting module rotationally connected between the upper body and the lower body and configured to adjust an irradiation angle when the at least one first lighting module rotates. The present disclosure provides the at least one first lighting module that can adjust the irradiation angle so that the irradiation angle and an irradiation range of the lighting lamp can be adjusted, which solves a technical problem that the irradiation angle of a conventional lighting lamp can't be adjusted.

An illumination device for illuminating a region monitored by at least one image sensor. The illumination device has at least one light source carrier with at least one light source arranged thereon. Furthermore, the illumination device has a control and interface unit and an adjusting unit, which can be actuated by the control and interface unit and with which the light source carrier is positionally adjustable.

A luminaire includes a lamp barrel having a light source detachably connected with a lens assembly. The lens assembly includes a lens barrel detachably connected with the lamp barrel and a focusing member on the lens barrel. An adjusting assembly includes a rotatable focusing ring, a lens fixing ring and a lens. The focusing ring includes a spiral groove on an inner surface. The lens fixing ring includes a projected rail on an outer surface. The lens barrel includes a bar shaped through hole extending along an axial direction. The projected rail passes through the bar shaped through hole and is mated with the spiral groove by clearance fit. Rotation of the focusing ring acts on the projected rail through the spiral groove and drives the lens fixing ring and the lens forward and backward in the lens barrel to adjust a distance between the lens and the light source.
