Disclosed are methods and apparatuses for creating hypermobile joints; hypermobile magnetic joints; super hypermobile joints; and super hypermobile, super magnetic joints. Joints can be simple magnetic, where one ferromagnetic element is a permanent magnet and the other is not; or super magnetic, where both are permanent magnets. Super hypermobile magnetic joints are created with two enclosures, joined magnetically and free to rotate around the other, with ferromagnetic elements inside the enclosures magnetized. As the moments of the magnetic domains of the enclosed magnetized ferromagnetic elements align parallel to each other inside each enclosure, as well as to the moments of the magnetic domains of the other magnetized ferromagnetic elements inside the other enclosure, the resulting magnetic attraction/attachment brings the enclosures together completing the joint. The frictional forces on the surfaces of the enclosures maintains the positions of the enclosures, and thus the joint.

A lighting fixture includes a light emitting module, a first brightness enhancement component and a second brightness enhancement component. The light emitting module includes a light emitting surface. The first brightness enhancement component is disposed on the light emitting surface and corresponds to a first light emitting area of the light emitting module. The first brightness enhancement component concentrates light emitted from the first light emitting area with respect to a first plane, wherein the first plane is defined by a first axis and a first direction perpendicular to the first brightness enhancement component. The second brightness enhancement component concentrates light emitted from the second light emitting area with respect to a second plane, wherein the second plane is defined by a second axis and a second direction perpendicular to the second brightness enhancement component, and the first axis is not parallel to the second axis.

A lighting device with changeable beam angle and fixed center beam candle power. The device may include a light source, an electronic driver for driving the light source to emit light, a beam shaping element for shaping a beam of light emitted by the light source, a beam angle adjustment mechanism configured to change a positional relationship between the light source and the beam shaping element, and a sensor configured to provide a signal indicative of a setting of the beam angle adjustment mechanism. The electronic driver is configured to adjust the luminous flux emitted by the light source depending on the signal provided by the sensor. Such a lighting device may keep the center beam candle power of the emitted light constant when the beam angle is changed.
