The light guiding radiation portion includes a light incidence portion having an incidence surface on which the light from the light source is made incident, and a plurality of radiation mechanisms that respectively radiate to a plurality of radiation angle ranges. The incidence surface includes a close side incidence region and a distant side incidence region. The radiation angle ranges include a close side radiation angle range and a distant side radiation angle range. The light incident on the close side incidence region is radiated to the distant side radiation angle range via a corresponding distant side radiation mechanism.

A multi-color LED illumination device and specifically a lens comprising a cylindrical opening extending into the lens from a light entry region at which one or more LEDs are configured. A concave spherical surface extends across the entirety of the light exit region of the lens, and a TIR outer surface shaped as a CPC extends between the light entry region and the light exit region. There are various diffusion surfaces placed on the sidewall surface of the cylindrical opening, as well as its upper planar surface and, depending on whether glare control is not needed, the exit surface of the lens. Lunes can also be configured on the sidewall surfaces of the cylindrical opening and if lessening glare is needed, also on the TIR outer reflective surface. The combination of lunes, diffusion elements, and the overall configuration of the lens provides improved color mixing and output brightness.

A lens and an illumination method thereof relates to the field of illumination technologies. The lens is provided with a concave space for accommodating a light source, a first irradiation part is formed on a first side of an inner wall of the concave space, and second irradiation parts are formed on the bottom and a second side of the inner wall of the concave space; a main light beam emitted by the first irradiation part and a main light beam emitted by the second irradiation parts form an acute angle. By means of the present invention, an upper region and a lower region of a to-be-irradiated object can be illuminated through one light source at the same time, and the light source arrangement cost is reduced.

An illumination device includes a plurality of light-emitting elements (LEEs); a light guide extending in a forward direction from a first end to a second end to receive at the first end light emitted by the LEEs and to guide the received light to the second end; an optical extractor optically coupled to the second end to receive the guided light, the optical extractor including a redirecting surface to reflect a first portion of the guided light, the reflected light being output by the optical extractor in a backward angular range, and the redirecting surface having one or more transmissive portions to transmit a second portion of the guided light in the forward direction; and one or more optical elements optically coupled to the transmissive portions, the optical elements to modify the light transmitted through the transmissive portions and to output the modified light in a forward angular range.

At least some of exit surfaces of the plurality of facets have a shape of a portion of an aspherical lens or an anamorphic lens.

A color mixing lens assembly is provided. The color mixing assembly may include a center mixing structure arranged concentrically within the optic. The center mixing structure may be configured to receive a first portion of electromagnetic radiation from a light receiving structure. The center mixing structure may include a plated surface. The center mixing structure may include a center kick structure arranged concentrically within the center mixing structure. The center kick structure may be configured to reflect the first portion of the electromagnetic radiation towards the plated surface. The center mixing structure may be configured to reflect the first portion of the electromagnetic radiation from the plated surface through an exit surface of the optic. The optic may be configured to reflect a second portion of the electromagnetic radiation received from the light source structure through the exit surface of the optic.

A recessed lighting apparatus comprising a cap provided with an apex comprising a first opening, adapted to accommodate at least one lighting source, and a second opening, of greater dimensions than the first opening, adapted to emit the light flow emitted from the lighting source. Starting from the interior of the apparatus towards the exterior of the apparatus, the cap can comprise a first cap made of a transparent material acting as a catadioptric reflector and a second cap made of an opaque material which is separated from said first cap by a gap.

A light emitting module including: a light guide member including: an emission region defined by a sectioning groove, a light source placement part located in the emission region, and a light adjusting hole; and a light source disposed in the light source placement part. In the schematic top view: the light adjusting hole is not positioned on a first straight line connecting (i) a center of the light source and (ii) a point in the sectioning groove that is farthest from the center of the light source, and a first lateral face of the light adjusting hole has a first region, and a line normal to the first region is oblique to a second straight line connecting (i) the center of the light source and (ii) a point in the sectioning groove that is closest to the center of the light source.

An optic for aisle lighting includes a portion of an optical material defined by a length and a cross-sectional profile. The cross-sectional profile is characterized by a cavity within the optical material, two upwardly-facing surfaces of the optical material on opposite sides of the cavity from one another, and downwardly-facing surfaces of the optical material. The cavity is bounded by an upward facing aperture, and at least three faces of the optical material that meet at interior angles. Light received through the upward facing aperture is separated at the interior angles, and refracted by the faces of the optical material, into separate light beams equal in number to the faces. The two upwardly-facing surfaces internally reflect the separate light beams downwardly. The downwardly-facing surfaces intercept respective portions of the separate light beams, and refract the portions as they exit the optic.

The present invention relates to an optical device comprising a light source that in turn emits a light beam, and that enables a predetermined area to be illuminated with a very high degree of uniformity in a plane perpendicular to said optical device, such that the orientation of the light beam is changed, illuminating only said predetermined area, where, due to the low profile thereof, the optical device enables same to be integrated into a luminaire with a reduced height dimension, which is also object of the present invention.
