The invention provides a lighting unit having an internal controller. The external power connector of the lighting unit (i.e. the electrical connector plug for connecting the lighting unit to an electrical lighting socket) comprises a manual adjustment element for selecting a setting of the controller. Thus, the manual adjustment element, which functions as a manual user interface, is integrated into the electrical plug part of the lighting unit.

Lighting unit such as a bulb

Disclosed is an optical element () comprising a central cavity () extending from a first aperture () to a second aperture () of the optical element, said central cavity gradually widening in a direction from the first aperture to the second aperture, said central cavity being delimited by a stack of transparent frustums () including a first frustum defining the first aperture and a final frustum defining the second aperture, each frustum having a prismatic outer surface () having a first surface portion () tapering in the direction from the second aperture to the first aperture and a continuous inner surface (), wherein the respective continuous inner surfaces combine to delimit said central cavity. Also disclosed is a lighting device including such an optical element and a luminaire including such a lighting device.

Optical element, lighting device and luminaire

Disclosed is a lens () for a lighting device () comprising a solid state lighting element (), the lens comprising a light exit surface (); a central lens portion () opposite said light exit surface; an inner annular reflective element () opposite said light exit surface and extending away from said light exit surface by a first distance (d), said inner annular reflective element delimiting said central lens portion; and a side surface defined by an outer annular reflective element () opposite said light exit surface and extending away from said light exit surface by a second distance (d) that is larger than the first distance such that the outer annular reflective element extends beyond the inner annular reflective element. A lighting device such as a light bulb including such as lens is also disclosed.

Lens and lighting device

A LED light bulb () having at least one LED (-). Light output from the LED is directed toward an offset scattering optics structure () that intersects and scatters the light output. The LED may optionally be paired with a narrow beam optical piece (--) to focus and direct the light output of the LED toward the scattering optics structure. A mounting structure () may support the scattering optics structure and offset the scattering optics structure from the LED.
