Light control films, and lighting devices including the same, are disclosed. The light control films include a single layer of light transmitting material having a first side and a second side. A plurality of first microstructures are formed in the first side. The first microstructures are configured to receive incident light from a light source and produce an off axis (e.g. batwing) light distribution in a field downstream of the second side of the light control film. In some embodiments, a plurality of second microstructures is formed on the second side of the light control films and are configured to reduce the glare produced by light emitted from the light source passing through the film.

A multi-beam solid-state luminaire including a plurality of solid-state lamps and a plurality of beam forming optics including a first group of beam forming optics and a second group of beam forming optics. In some embodiments, the beam forming optics may be arranged in a pattern having a center, and one or more center beam forming optics of the first group may be positioned at the center of the pattern. In some embodiments, luminaire may include a first beamwidth lens positioned over the first group of beam forming optics and a second beamwidth lens positioned over the second group of beam forming optics. The beamwidth lenses may emit light from the solid-state lamps having different respective beamwidths. The luminaire may provide a decorative flame-like pattern on a target surface.

A taillight assembly including a support member, a right light assembly, a right lens assembly, left light assembly, and a left lens assembly. The right and left light assemblies are mounted to a light supporting portion of the support member. The right assembly includes a first light source oriented to direct a first beam of light in a rearward direction and a second light source oriented to direct a second beam of light in a rightward direction. The left light assembly includes third light source oriented to direct a third beam of light in rearward direction and a fourth light source oriented to direct a fourth beam of light in a leftward direction. The right and left lens assemblies are mounted to the light supporting portion to house the right and left light assemblies, respectively, and cooperate to disperse the first, second, third, and fourth beams of light 270 degrees horizontally.

A luminaire for disinfecting a target surface includes a disinfecting light source, a non-disinfecting light source, a beam angle adjustor, a motion sensor, and a distance sensor. The radiance of the disinfecting light is calculated based on detected distance to a target surface and beam angle, and may be selected to achieve a predetermined irradiance of the target surface. If no motion is detected by the motion sensor then the disinfecting light source is set to ON and the non-disinfecting light source is set to OFF. If motion is detected and a beam intercept is not detected by the distance sensor then the disinfecting light source is set to DIM and the non-disinfecting light source is set to ON. If motion is detected and a beam intercept is detected then the disinfecting light source is set to OFF and the non-disinfecting light source is set to ON.

A method for manufacturing a rotationally adjustable lamp (1) is disclosed. The method comprises: molding a shell (6) having a guiding slot (7a); providing a base (2) configured to receive the shell (6) and connect to a lamp socket; inserting the shell (6) into the base (2) so as to enclose the guiding slot (7a) by the base (2); and forming in the base (2), when the shell (6) is inserted into the base (2), a notch (5) protruding into the guiding slot (7a), the notch (5) being movable along the guiding slot (7a) so as to allow for the shell (6) to be rotated relative to the base (2).

Provided is a lighting device that converts an exiting light into a stereoscopic light having a sense of depth or a sense of volume, whereby light images having stereoscopic effects can be implemented using light emitted from a light-emitting device and simultaneously, a structure of a printed circuit board (PCB) located at a lower portion of a light passage portion is eliminated and a direct-type light-emitting device located at sides of the light passage portion and having high versatility is used such that flexibility of the light passage portion is attained and a degree of freedom of a design can be enhanced.
