An illumination device (100) provided with a support structure (10), an array of a plurality of spatially separated solid state lighting elements (11) mounted on a first side of the support structure (10), as well as an optical element (12) made from a light diffusing material for diffusing light emitted by the array of the plurality of spatially separated solid state lighting elements (11), the optical element (12) being mounted on the first side of the support structure and provided with a pattern formed of an array of a plurality of recessed portions (120) and an array of a plurality of elevated portions (122).

A luminaire includes a light emitter, an asymmetric lens, and a mechanism. The light emitter includes an exit aperture and emits a light beam having an optical axis. The asymmetric lens receives the light beam and projects a projected beam. The mechanism rotates the light emitter about an axis of rotation passing through the exit aperture, thereby moving a point of entry of the light beam into the asymmetric lens. A size and location of a hot-spot of the projected beam varies as the point of entry of the light beam into the asymmetric lens moves. The asymmetric lens includes a long axis, a short axis, and an asymmetric surface, which has a long axis parallel to the long axis of the asymmetric lens. The asymmetric surface is asymmetric in a cross-section taken in a plane perpendicular to the short axis of the asymmetric lens.

A situational air bubble spa machine is provided, which includes a control host, an air provider, pipe fittings, and a bubble bathmat. The control host is communicated to the air provider. The air provider and the bubble bathmat are connected through the pipe fittings. The control host includes a main body, a light emitting element arranged inside the main body, a control button set arranged on the top surface of the main body. The control button set includes a startup/shutdown button which is used to regulate the startup/shutdown of the control host, an intensity button is used to regulate the air flow provided by the air provider to the bubble bathmat, thereby regulating the bubble density, and a lighting button is used to control the startup, shutdown, and lighting mode of the light emitting elements, and a fixing bracket is arranged on the bottom surface of the main body.
