  • Patent number: 9013696
    Abstract: The present invention relates to a light quality evaluating device, comprising a light receiving unit, first processing unit, a memory unit, a second processing unit, a display unit, and a power management unit, and being used for evaluating the light quality light based on physiological perception of human. In evaluating operation, it transfers a power spectrum of the light emitted from a light source to a luminance spectrum of light through a luminosity function. Next, the method compares the luminance spectrum of light with a corresponding luminance spectrum of blackbody radiation thereof. Therefore, an index of spectral resemblance with respect to the black body radiation (SRBR) would be calculated and then obtained, such that the SRBR can be used for evaluating the quality of the light emitted from the light source. Moreover, comparing to conventional CRI, SRBR is a better light quality evaluating method because of having fairness and consistency.

  • Publication number: 20140313512
    Abstract: The present invention relates to a light source quality evaluating method by using spectral resemblance with respect to the blackbody radiation, which mainly comprises 5 method steps. This method is used for evaluating the quality of light based on physiological perception of human. In evaluating operation, the method firstly transfers a power spectrum of a light source to a luminance spectrum of light source through a luminosity function. Next, the method compares the luminance spectrum of light source with a luminance spectrum of the blackbody radiation thereof. Therefore, an index of spectral resemblance with respect to the black body radiation (SRBR) would be calculated and then obtained, such that the SRBR can be used for evaluating the quality of the light source. Moreover, comparing to conventional color rendering index (CRI), SRBR is a better light source quality evaluating method because of having fairness and consistency.

  • Publication number: 20140252320
    Abstract: The present invention relates to a full-band and high-CRI organic light-emitting diode, comprising: a first conductive layer, at least one first carrier transition layer, a plurality of light-emitting layers, at least one second carrier transition layer, and a second conductive layer. In the present invention, a plurality of dyes are doped in the light-emitting layers, so as to make the light-emitting layers emit a plurality of blackbody radiation complementary lights, wherein the chromaticity coordinates of the blackbody radiation complementary lights surround to a specific area on 1931 CIE (Commission International de'Eclairage) Chromaticity Diagram, moreover, the specific area fully encloses the Planck's locus on 1931 CIE Chromaticity Diagram, such that the blackbody radiation complementary lights mix to each other and then become a full-band and high-CRI light.

  • Publication number: 20140017627
    Abstract: An auxiliary device for an articulator includes a base and at least an adjusting structure. The base is provided for positioning an articulator, and the adjusting structure is disposed on the base. The adjusting structure includes a first ball joint, a second ball joint and a connecting assembly. The first ball joint is connected to the base, and the two ends of the connecting assembly are connected to the first ball joint and the second ball joint, respectively. The adjusting structure is moved relatively to the articulator by the movement of at least one of the first ball joint and the second ball joint, thereby adjusting the position of a dental cast disposed on the articulator. The auxiliary device is advantageous for conveniently adjusting the dental cast disposed on the articulator and accelerating the process of the preoperative planning.
