  • Patent number: 11408573
    Abstract: The present disclosure is directed to projection devices that can project patterned light of different colors. In one implementation, the projection device can include a housing, within which reside multiple components. These components can include light emitting diodes (LEDs), a parabolic mirror reflector, a sinusoidal lenticular diffuser, and multiple spatial filters. The multiple LEDs can be provided in at least two distinct colors. The parabolic mirror reflector can be arranged to collimate light received from the multiple LEDs. The sinusoidal lenticular diffuser can be positioned at an output of the parabolic mirror reflector and arranged to diffuse the collimated light. The spatial filters can be arranged to diffuse the diffused and collimated light received from the sinusoidal lenticular diffuser. An imaging lens can be coupled to the housing and arranged to magnify the diffused light received from the spatial filters and display a cloud-like effect on a first surface.

  • Patent number: 11402738
    Abstract: An illumination system including an exciting light source module, a wavelength conversion device and a light uniforming module is provided. The exciting light source module is configured to emit an exciting beam. The wavelength conversion device is disposed on a transmission path of the exciting beam and is configured to rotate around a central axis. The light uniforming module is disposed on the transmission path of the exciting beam and between the exciting light source module and the wavelength conversion device. After the exciting beam emitted from the exciting light source module passes through the light uniforming module, the exciting beam forms a light spot on the wavelength conversion device. The energy intensity distribution of the light spot along the radial direction about the central axis is that the energy intensity is lower in the center and higher on the two sides. A projection apparatus is also provided.

  • Patent number: 11353202
    Abstract: Systems and methods for using light switches to control lighting and other functions are disclosed. Each switch may be a manual switch that is mounted to a wall. A biasing device may be positioned proximate each switch. When a user moves the switch out of a first position and into a second position or toward a second position, the delivery of household power to one or more light units may be interrupted. However, when the user releases the switch, the biasing device may provide an immediate automatic return of the manual switch to the first position. The resulting short interruption in household power may be used as a signal for controlling operation of the one or more light units and/or other electronic devices installed at one or more lighting sites corresponding to the switch.
