  • Patent number: 9115872
    Abstract: A lighting device includes a base, a light source, an optical color wheel, and a lens. The base has a plurality of fins for heat dissipation. The light source is disposed in the base, and the optical color wheel is disposed above the light source and in contact with the base. The lens is movably disposed on the base. The Light from the light source passes through the optical color wheel to form colored light. The colored light passes through the lens to form a light beam. Heat generated by the light source and the optical color wheel is dissipated by the fins.

  • Patent number: 8944633
    Abstract: A lighting device includes a lighting unit, a base, a lighting trim, a connecting unit, at least one pull rope, and a plurality of resilient latching members and linking members. The base and the lighting trim are disposed on respective ends of the lighting unit. The base has a receiving hole formed thereon. At least one hole is formed on a flange portion of the lighting trim and is corresponding to the at least one pull rope. The connecting unit is received by the receiving hole and connected between one end of the pull rope and the resilient latching members. The other end of the pull rope is passed through the hole. The resilient latching members are disposed around the base and corresponding to the respective linking members.

  • Patent number: 8920003
    Abstract: A luminaire includes a first body module, a light module, a second body module, a wire-receiving unit, and a wire. The light module is disposed on said first body module. The second body module is movable telescopically relative to the first body module. The wire has two ends respectively and electrically connected to the first and second body modules, and a portion that is received within the wire-receiving unit and that is movable at least partially into or out of the wire-receiving unit as a result of adjusting the length of the luminaire, thereby preventing entanglement of the wire.

  • Publication number: 20120194068
    Abstract: A lamp includes a housing, a plate body disposed in the housing and having a wavelength-conversion material, a light-emitting module disposed in the housing and spaced apart from the plate body, and a light sensor disposed on the plate body. The light-emitting module includes a circuit board, and a plurality of light-emitting units disposed on the circuit board and emitting light onto the plate body. The light sensor is used for sensing the color temperature of light that is emitted from the light-emitting units and that propagates within the plate body.
