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.

A lighting system includes a lighting device within a luminaire that generates a controllable light output. The lighting system also includes an input device within the luminaire. The input device includes a first selection mechanism communicatively coupled to the lighting device. The first selection mechanism receives a first input to transition the lighting system between a set of control states. The input device also includes a second selection mechanism communicatively coupled to the lighting device. The second selection mechanism receives a first rotational input to control a light intensity output of the lighting device or a correlated color temperature of the lighting device.

A combined-type dynamic effect wheel includes a light source and an effect wheel bottom plate. The effect wheel bottom plate is provided with a light-through hole and several pattern bases, each pattern base being provided with a pattern sheet. A first rotating assembly and a second rotating assembly are provided at the center of the effect wheel bottom plate, and the effect wheel bottom plate is driven by the first rotating assembly to rotate so as to enable different pattern bases or the light-through hole to be switched in or out of a light beam; the pattern base is provided with a driven assembly; and the size of an effective pattern on the pattern sheet is greater than the size of an effective light spot of the light beam passing through the pattern sheet.

A wall lamp has a lamp housing having multiple decorative holes, a front decorative plate, an LED lighting assembly, and a rotating driver. The LED lighting assembly is disposed in the lamp housing and has multiple LED components. The rotating driver is mounted in the lamp housing and is connected to the LED lighting assembly. The LED lighting assembly driven by the rotating driver is rotated to change projecting positions of the LED components relative to the decorative holes of the lamp housing for generating a dynamic lighting effect that resembles peacock feather spreading and increasing dynamic variations of a decorative effect of the wall lamp.

A light emitting module includes: a substrate; a first light source mounted on the substrate, the first light source comprising a first light emitting element configured to emit first light, a light reflecting member surrounding lateral faces of the first light emitting element, and a first wavelength conversion member configured to convert a wavelength of a portion of the first light and to emit second light, such that the first light source is configured to output light that includes the first light and the second light, the first wavelength conversion member covering the first light emitting element and extending out from the lateral faces of the first light emitting element when viewed from above; and a first lens on which the light output from the first light source is incident.

A lighting device comprises a planar array of LEDs comprising a set of parallel LED strips and an optical sheet extending over and parallel to the plane of the array of LEDs. The optical sheet comprises an interleaved pattern of parallel optical strips and pass through strips and it is movable relative to the array of LEDs to create different output beam characteristics.

A flickering source of illumination is disclosed. A first, second and third group of LEDs and a control circuit are also disclosed. The control circuit is adapted to control a switch to selectively switch on the first group, the second group, and the third group of LEDs. The flickering source of illumination includes a translucent mineral positioned around the groups of LEDs. The translucent mineral is adapted to allow light emitted by the LEDs to pass through the translucent mineral and illuminate an area adjacent to the translucent mineral. The flickering source of illumination may include a first group of LEDs; a second group of LEDs; and a control circuit. The control circuit may be adapted to control a light output of the first and second groups of LEDs so that the first group of LEDs emits a different color of light than the second group of LEDs. The control circuit may be further adapted to selectively vary a color of the light output of the first group of LEDs and of the second group of LEDs. A translucent mineral positioned around the LEDs is also disclosed. The translucent mineral may be adapted to allow light emitted by the LEDs to pass through the translucent mineral and illuminate an area adjacent to the translucent mineral. The translucent mineral may be selected from a group including a salt rock, quartz, marble and natural stone.

A system intended to be used for lighting purposes of an environment, where a light measurement at a wavelength is performed, is also desired to be monitored, without affecting the measurement performed in a dark environment.
