  • Patent number: 9086227
    Abstract: A light collection system including a light concentrating device and a reflective curving-surface device is provided. The light concentrating device receives at least a portion of an incident light and forwardly emits the portion of the incident light after concentrating and passing it through a first focal region, so as to obtain a first-stage output light. The reflective curving-surface device has an entrance aperture for receiving the first-stage output light. The reflective curving-surface device includes a reflective inner curving surface, and at least a portion of the reflective inner curving surface has a second focal region. The first focal region and the second focal region are confocal or approximately confocal within a range. As a result, at least a portion of the first-stage output light is confocally converted into a forwardly emitted second-stage output light.

  • Patent number: 7669782
    Abstract: The present invention provides a liquid atomizer for atomizing liquid and applied in an atomizing device having an accommodating space and a through hole. The liquid atomizer includes a vibrating element having a first hole corresponding to the through hole; a spray plate having a plurality of spraying holes corresponding to the first hole and being connected with the vibrating element; and a structure element having a second hole corresponding to the plurality of spraying holes of the spray plate and being connected with the spray plate so that the spray plate is disposed between the vibrating element and the structure element. The vibrating element, the spray plate and the structure element are assembled in the accommodating space of the atomizing device. Liquids are atomized via the spraying holes of the spray plate.
