A system for use with a billiards table may include addressable multicolor LED strips, a controller and a user device. The controller may be configured to send signals through the LED strips to control which one or more pixels are activated and one or more colors of light to be produced by corresponding one or more LEDs for the one or more activated pixels. The user device may communicate with the controller and may implement a program configured to enable a user of the user device to send lighting commands to the controller during gameplay. The lighting commands may indicate user-desired changes to lighting provided by the addressable multi-color LED strips. The controller may send corresponding signals to the addressable multi-color LED light strips to implement the changes to the lighting.

A project light device comprises multiple light assemblies and at least one pivotable connecting assembly. The at least one pivotable connecting assembly is connected between two adjacent light assemblies. Each light assembly comprises a shell, and a light-emitting module and a light-concentrating structure that are mounted inside the shell. The light-concentrating structure concentrates light emitted from the light-emitting module to project light out of the shell. The at least one pivotable connecting assembly comprises a joint seat, a middle pivotable rod and a joint rod. The joint seat and the joint rod are respectively mounted at two adjacent light assemblies. The joint rod is pivotably mounted at the middle pivotable rod pivotably mounted at the joint seat. The two adjacent light assemblies are connected through the pivotable connecting assembly, thereby being pivotable relative to each other, so the light assemblies project lights to different directions.

Disclosed embodiments relate to a combination axial fan and LED lighting system configured to fit into the footprint of a standard ceiling tile. Disclosed embodiments further include ceiling tiles with a built-in fan and/or LED lighting. The disclosed systems may include one or more UV-C light sources which irradiate contaminants as air flows through the UV-C unit. The UV-C unit is mounted on either a universal mounting mechanism or a mobile support unit to provide mobility to the UV-C unit.

A portable light up mirror includes a mirror element, a case element for installing the mirror element, a cover element which is coupled with the case element for covering the mirror element, and a light source which is arranged behind the mirror element within the case element for providing even and glare-free illumination, so that the adequate lighting minimizes shadows on a user's face and give the user a more accurate view when grooming or applying cosmetics.

A light fixture includes a frame that includes a plurality of frame pieces configured for assembly around a ceiling tile to form the light fixture. Each of the plurality of frame pieces include an L-shaped diffuser and a circuit board that includes a plurality of light sources to emit illumination. The L-shaped diffuser includes a diffuser body that is asymmetric in transparency to direct more illumination from the light sources to inside the ceiling tile than outside the ceiling tile. The diffuser body includes an outside wall that is substantially opaque, an inside wall that is at least partially substantially transparent, and a bottom wall that is substantially transparent. The light fixture can further include a connector to connect adjoining frame pieces together, which includes a substantially opaque portion below the circuit board and a substantially transparent portion above to allow illumination to pass between the adjoining frame pieces.

A luminaire includes a support positioned in a ceiling. A light module is connected to the support having a base, a light emitter, and an optic. The light modules allow different luminaire configurations to be formed out of similar components.

A light source can include at least one light emitter and is configured to emit a first light during a region of a light period and emit both the first light and a second light of a different wavelength during a remaining region of the light period. The emitter can include semiconductor layers and an active layer configured to emit light having a specific wavelength due to a band gap difference in an energy band depending on a material used to form the active layer. A plant cultivation device can include the light source and a main body in which a plant can be grown. The light period can be configured to increase a content of an active ingredient in the plant. The first light can have a longer peak wavelength than a peak wavelength of the second light.
