A holiday or event decoration that is able to synchronize media shows between multiple devices.

A solid-state lamp includes a first plurality of solid-state emitters that emit light at visible wavelengths and a second plurality of solid-state emitters that emit light at a safe ultraviolet wavelength, wherein the second plurality of solid-state emitters emit light at least when the first plurality of solid-state emitters emit light.

A lighting device according to an embodiment includes a sensor, a substrate disposed on the sensor and including an electrode pattern, a light source disposed on the substrate and electrically connected to the electrode pattern, a resin layer disposed on the substrate, and a reflective layer disposed between the substrate and the resin layer, and the substrate may include a first region overlapping the sensor in a first direction perpendicular to an upper surface of the substrate, a second region surrounding the first region, the light source may be disposed on the second region, the plurality of reflective pattern groups may be disposed on the first region, and the sensor may not overlap the light source and the electrode pattern in the first direction.

A ceiling lamp is disclosed including a first lamp, a second lamp, and an angle adjusting and locking device. The first lamp and the second lamp are arranged at an interval, and the second lamp and the first lamp are rotatable with respect to each other. The angle adjusting and locking device is connected with the first lamp and the second lamp, and the angle adjusting and locking device is configured for locking the first lamp and the second lamp after they are rotated with respect to each other.

Systems and methods are disclosed for configuring a light integrated device, and include receiving sensed data from a first sensor, providing the sensed data from the first sensor to a machine learning model, receiving a machine learning output from the machine learning model based on the sensed data from the first sensor, the machine learning output comprising a light integrated device configuration, wherein the light integrated device configuration comprises a dual light emitting diodes (LED) setting, and configuring the light integrated device based on the light integrated device configuration.

The utility model discloses a pattern projecting apparatus for automatically identifying and playing an audio. The projecting apparatus includes a first housing, a light-emitting assembly, a film assembly, an audio assembly, and an imaging assembly. The audio assembly includes a control board, an electronic label corresponding to a film sheet, an identifying module for identifying the electronic label and arranged on the control board, a storage medium pre-stored with an audio corresponding to a galactic starry sky pattern, and a speaker electrically connected to the control board. The electronic label is arranged on the film assembly. When the film assembly is mounted in a first mounting hole, the identifying module identifies the electronic label on the film sheet, positions the audio corresponding to the electronic label in the storage medium and plays the audio via the speaker, so that the galactic starry sky pattern projected by the projecting apparatus is played in combination with the audio. A user can hear an audio corresponding to a pattern of the film sheet when changing different film sheets. Therefore, the user's experience is effectively improved, and the practicability of the projecting apparatus is enhanced.

A momentum wheel toy comprises a track having two track sections and a wheel. The wheel has a ferromagnetic axle positioned through its center, with a first end and a second end that each ride upon a track section. The two track sections are separated by a spacer which separates the walls enough to allow the first end and second end of the ferromagnetic axle to ride on the ferromagnetic strips positioned around the perimeter of each of the first track section and the second track section. A handle opening through the device allows the toy to be rocked back and forth, creating the momentum energy for the wheel to go around the track.

A lighting apparatus is provided with a housing forming a battery housing and a light housing separated via a partitioning wall. A light module is supported by the light housing and includes a heat sink located at least partially within the light housing and at least one LED supported by the heat sink. A battery receptacle formed within the battery housing to slidingly receive a battery pack at least partially into the battery housing. An intake opening is formed within the partitioning wall and an air vent is formed in fluid communication with the light housing. In operation, an airflow passes in thermal contact with the battery pack from the battery housing into the light housing through the intake opening, and from the light housing in thermal contact with the heat sink out of the air vent.

A lighting device is disclosed with one or more magnetic control switches to adjust the power modes of the lighting device.
