A light device includes a transparent substrate having a first surface and a second opposite surface, an array of light-modifying elements formed on the substrate, and a light source to project light along a thickness direction of the substrate. The light-modifying elements having surfaces inclined at an angle with respect to at least one of the first surface and the second surface, and configured to diffuse light by reflecting and/or refracting incident light.

A light emitting device with a rotating form thereon, said device having a motor and a power source contained within a generally durable housing having a lens and an elongated spire extending outside of the durable housing and through an opening contained within the lens, said elongated spire additionally having a decorative rotatable form positioned on a distal end of the elongated spire, and at least one light source directing emitted light at the rotatable form, such that crisp hard shadows are produced on outlying surfaces. A power source is provided, connected to a motor and processor so as to move or rotate the spire and thus the form, causing the lights to cast moving decorative shadows on an exterior surface.

A luminaire includes a white light LED light source emitting a light beam that that is filtered by first and second color filters. An optical device modifies the filtered light beam. A control system receives a commanded value for the optical device and responds by causing the optical device to move based on the commanded value; determining a Duv change in the light beam caused by the optical device; determining positions for the color filters based on the Duv change, a current correlated color temperature (CCT) isotherm value, and a current Duv value; and moving the color filters to their determined positions. The control system may alternatively receive a command with a Duv value and respond by determining color filters positions based on the received Duv value and a current CCT isotherm value; and moving the color filters to their determined positions.

Disclosed is a light projector. The light projector includes a housing, a support mechanism, an optical lens, a light-emitting assembly, and a drive device. The light-emitting assembly includes a water ripple optic, a control board, at least one incoherent light source, and at least one coherent light source. One side of the water ripple optic is arranged facing the optical lens, and the control board is arranged on the other side of the water ripple optic. The control board is provided with a first through-hole and a second through-hole. The drive device passes through the first through-hole and is connected to the water ripple optic to drive the water ripple optic to rotate. The coherent light source is arranged in the second through-hole, and the incoherent light source is arranged on one side of the control board facing the water ripple optic, which effectively increases diversity of lighting effects.

A projection device includes a first light-emitting component including a first light-emitting member, a first light-transmitting member, a first driving member and a first lens. The first light-emitting member is used for generating a linear light band; the first light-transmitting member is defined with a first linear light-transmitting region; the first driving member is fixedly connected with the first light-emitting member or the first light-transmitting member, and used for allowing the first light-emitting member and the first light-transmitting member to generate a relative motion, and allowing the linear light band to intersect with the first linear light-transmitting region; and the first lens, the first light-emitting member, the first light-transmitting member and the first lens are sequentially arranged. The projection device of the present disclosure is capable of generating the dynamic meteor effect to improve the user experience.

The present disclosure provides decorative lights using prismatic film such as Optical Lighting Film (OLF) available from 3M Company, and a diffuse partial reflector. The decorative lights generate design styles and comfort for a light fixture, and can use solid state lighting such as Light Emitting Diodes (LEDs) to generate the light. The decorative lights can have an appearance that changes with the viewing angle of the light.

A decorative light can include: a housing defining an interior space and having an open front; a cover mounted to the open front of the housing, the cover including a beam-splitter light lens shade and a substantially planar lens portion disposed around the beam-splitter light lens shade; a motor located in the interior space of the housing, the motor including an output shaft; a first light module located in the interior space and including first light units disposed about the output shaft of the motor, where the output shaft is rotatable with respect to the first light units; a second light module located in the interior space and including second light units disposed about the output shaft of the motor, wherein the output shaft is rotatable with respect to the second light units; and a rotating lens module connected to the output shaft of the motor for rotation.

A simulating neon lamp is disclosed, which comprises a bottom base (10), a back, light source (20), a display assembly (30) and a cover plate (40); wherein the bottom case (10) is opaque and hollow and has an opening facing upward; the back light source (20) is mounted in the bottom case (10); the display assembly (30) is translucent and fixed onto the bottom case (10) to close the opening; the display assembly (30) comprises a first display panel (31); the sectional width of the first display panel (31) is less than that of the bottom case (10), and an upper surface of a connection where the first display panel (31) is connected with the bottom case (10) is not higher than a top end of the bottom case (10): the cover plate (40) is opaque and covers the connection where the first display panel (31) is connected with the bottom case (10) so as to shield the light penetrating from a gap of the connection where the first display panel (31) is connected with the bottom case (10). The present invention has such advantages as safety, energy-conservation and low cost, excellent effect simulating a neon lamp and so on.

A lighting device comprises a light source defining a central axis and comprising at least two mutually independently operable lighting elements. The lighting device further comprises a rotatable deflective member rotatably mounted about said axis, and a fixed deflective member fixedly mounted on said axis and comprising at least two mutually differently deflective portions which each are associated with a respective lighting element. The lighting device of the invention enables various operation modes, like light beam rotation can rotate, jumping of the light beam from one location to another by a sequence of switching on and off one or more of the at least two lighting elements, or in that it can be dimmed or boosted, for example dimmable in steps by a sequence of one by one switching off the lighting elements.
