摘要： A lighting device according to one aspect of the present invention includes a plurality of thin plates whose surfaces facing a center are configured to absorb light. By rearranging the at least one thin plate by moving the at least one thin plate at an angle smaller than 360 degrees about an axis, it is possible to form a curved plate having a double right-angled spherical triangular shape by all of the plurality of thin plates.

摘要： An LED light engine and automated luminaire are provided. The LED light engine includes LED emitters, a first lens array, a color mixing module, second and third lens arrays, and a converging lens. The first lens array includes collimating lenslets corresponding to the LED emitters. The first lens array emits a plurality of light beams corresponding to the LED emitters. Each of the light beams includes substantially parallel light rays. The color mixing module includes dichroic filters that receive the light beams and emit corresponding filtered light beams. The second lens array includes converging lenslets that receive the filtered light beams. The third lens array includes other converging lenslets optically coupled to the second lens array. The converging lens is optically coupled to the third lens array. The second and third lens arrays and the converging lens illuminate a gate in an optical system with the filtered light beams.

摘要： 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 of the pattern bases 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, which is fitted and connected to the second rotating assembly and is driven by the second rotating assembly to rotate so as to drive the pattern sheet to rotate; 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, and when the pattern sheet is switched into a light path, the pattern sheet forms a dynamic pattern effect during the rotation. The present invention has the beneficial effect that multiple dynamic pattern effects can be switched as desired under the drive of the same driving structure.

摘要： A stage light with an additional visual effect includes a main light source and a lampshade, the main light source being located at a bottom of the lampshade. The stage light further includes an effect light source and a light-transmitting plate located at a light outlet of the lampshade. The effect light source and the main light source are controlled independently of each other. The light-transmitting plate has a first surface and a second surface, and a first side and a second side connecting to the first surface and the second surface, respectively. At least part of the light emitted by the effect light source enters from the first side and exits from the second side. The light emitting by the effect light source exits from the second side, so that the second side is illuminated, which decorates the stage light itself. Compared with the lighting effect that can only be shown at a target position by projection, it makes the stage light itself has certain attraction. The effect light source is used to render the light-transmitting plate alone. When the main light source is off, the effect light source can be turned on separately to light up the second side of the light-transmitting plate, with more obvious effect, and the decorative effect of the stage light itself is increased.

摘要： The present invention discloses a stage lighting framing system of rotation with wireless power transmission and wireless communication, comprising a rotating disc bracket, a fixing bracket fixedly connected with the rotating disc bracket, a wireless power supply device, and a framing and shaping mechanism rotatably connected with the rotating disc bracket, in which an electromagnetic field transmitting device is arranged on the fixing bracket, an electromagnetic field receiving device is arranged on the framing and shaping mechanism which is driven by a first drive device for unrestricted angle rotation. It further includes a wireless signal transmission device, and correspondingly a wireless signal receiving device arranged on the framing and shaping mechanism. The present invention can supply continuous power to a framing and shaping mechanism without a cable to achieve wireless power supply. Therefore, the framing and shaping mechanism will have greater rotational freedom and achieve richer light-beam shaping effects.

摘要： A method and apparatus is described for producing high brightness, e.g. multicolor light, whereby a region of a wavelength conversion element and a light source producing excitation light are moved relative to each other so that said region is exposed to the excitation light at different times and in a progressive movement that scans across a part of the entire surface of the wavelength conversion element. The wavelength conversion element can be cooled by air or with a liquid.

摘要： Electric lighting devices are described that utilize three or more light sources to generate a flickering flame effect. The light sources can emit light at different colors to more closely simulate the look of a flame. A projection system having a matrix of LEDs could be used to project an image of a flame on to a projection surface without the need or cost associated with a traditional or pico projector.

摘要： A vehicle headlamp system (100) includes a plurality of shades (12a, 12b, 12c, 112a, 112b, 112c, 102, 106) and a shade control section (58). When a first shade is in an operative position, the first shade shields light from a light source (14) in a first light shielding area. When a second shade is in an operative position, the second shade shields the light in a second light shielding area. When observed from a front of the vehicle headlamp (210), the first light shielding area and the second light shielding area overlap each other in a common light shielding area. The shade control section (58) is configured to control a shade actuating section (29, 114) such that, when moving the first shade from the operative position to the retracted position and moving the second shade from the retracted position to the operative position to switch a light distribution pattern, the light is continuously shielded in the common light shielding area.
