The light distributing component includes an inner ring polarizing lens and an outer ring polarizing lens, and the inner ring polarizing lens and the outer ring polarizing lens have a common axis center, and the outer ring polarizing lens surrounds the inner ring polarizing lens, the inner ring polarizing lens is configured to deflect light of a light-emitting unit toward a direction close to the axis center; and the outer ring polarizing lens is configured to deflect light of the light-emitting unit in a direction away from the axis center.

A ceiling fan is provided. The ceiling fan includes one or more fan blades. The ceiling fan further includes a motor. The motor is operatively coupled to the one or more fan blades. The motor is configured to drive rotation of the one or more fan blades. The ceiling fan further includes a light kit. The light kit includes a panel. The panel has an edge extending between a top surface of the panel and a bottom surface of the panel. The light kit further includes at least one light source positioned to illuminate the edge.

A lamp includes a base, a light emitting module mounted to the base, a lens member and a decorating unit. The lens member has a light input surface, a light output surface disposed in front of and spaced apart from the light input surface along an axis, and a through hole extending through the light input surface and the light output surface. Light emitted from the light emitting module enters the lens member through the light input surface and exits the lens member through the light output surface. The decorating unit is detachable and is optically disposed for decorating the lamp or for changing at least one of a wavelength, an output angle, a light field and so forth of the light passing through the lens member.

A lightguide functioning as a luminaire. The luminaire includes at least one solid state light source, such as an LED, and a lightguide configured to receive light from the solid state light source. Light from the light source is coupled into the lightguide and transported within it by total internal reflection until the light exits the lightguide. A shape of the lightguide causes and directs extraction of the light, and can also be used to create a particular pattern of the extracted light. Such shapes include linear wedges and twisted wedges. Optical films can be included on the light input and output surfaces of the lightguide.

Provided is a lighting apparatus. The lighting apparatus includes: a light source configured to emit light; a reflective member included an output region of the light and surrounded the output region; and a fluorescent layer formed on a part of a region of the reflective member.

A luminaire includes a first waveguide having a first primary light emitting surface directed in a first direction and a first secondary light emitting surface directed in a second direction. A second waveguide having a second primary light emitting surface directed in the second direction and a second secondary light emitting surface directed in the first direction. A first plurality of LEDs are optically coupled to the first waveguide and a second plurality of LEDs are optically coupled to the second waveguide. The first and second waveguides are independently operable. The first and second plurality of LEDs may comprise LED groups where each of the LED groups are independently controllable. The light emission pattern and light properties of the emitted light are controllable

A luminaire having a substantially two-piece housing with a first portion and a second portion, for example a cover and a base. The cover receives one or more control components. The base receives a light emitter assembly and the control component assembly is operatively connected to the lighter emitter assembly to control the light output therefrom. A lens assembly can be connected to the bottom of the base 14. Different mounting components can be connected to cover to connect the luminaire 10 to a support.

A smart LED lighting apparatus with communication capabilities. The lighting apparatus includes a main body, a bulb body, a head body, a LED module for emitting light, and a communication module for providing wireless communication. The bulb body is connected to a first end of the main body. The head body is connected to a second end of the main body and configured to be connected to an electrical socket for receiving power. The lighting apparatus further includes a composite printed circuit board having a first sub-board and a second sub-board physically coupled to the first sub-board. The communication module is located on the first sub-board and the light LED module is located on the second sub-board.

The invention relates to an illumination device (1) comprising an optical waveguide (2) and a number of (connections for) light sources (3)—especially LEDs—positioned along the waveguide (3). This waveguide has a central axis (4) at a distance r to the surface of the waveguide, said surface comprising a light entrance surface (6) on which the (connections for) light sources are positioned and a curved light exit surface (5), wherein, viewed along the circumference of the curved surface (5), the distance r to a first intersection (8) between the flat surface (6) and the curved surface (5), changes to a second distance of different value at the second intersection (9) between said surfaces. The invention also relates to a luminaire comprising such an illumination device (1). Due to the special design of the waveguide (2), the amount of reflections of light in the light sources is largely reduced and desired shaping of the exiting beam can be realized. The device can be further improved by the use of special features, like specially designed curved surfaces (5), reflective structures (13), channels (15) and torus-shaped waveguides.
