  • Patent number: 11927865
    Abstract: An electrochromic device with side-by-side structure including a common electrode unit, at least one color-changing unit and an electrolyte layer is provided. The common electrode unit includes an electrode layer and an electrode protection layer disposed on the electrode layer. The color-changing unit includes a transparent conductive layer and a color-changing layer disposed on the transparent conductive layer. The common electrode unit and each color-changing unit are arranged on the same plane with an insulating region between two adjacent units. The electrolyte layer covers and connects the electrode protection layer of the common electrode unit and the color-changing layer of each color-changing unit.

  • Patent number: 11599691
    Abstract: A computer implemented method for illumination planning is provided that includes providing a floorplan having at least one lighting space; and assigning functions to the at least one lighting space. The lighting space and functions assigned to the lighting space of the floorplan are matched to a historical lighting schema. A lighting layout is extracted from the historical lighting schema and matched to the lighting space. A light package is extracted from the historical lighting schema and matched to the lighting space. A calculation of lighting performance for the lighting layout and the light package that has been matched to the lighting space is conducted to determine whether the lighting performance meets a lighting standard or whether the lighting performance does not meet the lighting standard. The computer implemented method further includes producing a conclusion for the lighting scenario for suitability to the floorplan and functions.

  • Patent number: 9671088
    Abstract: Various embodiments may relate to a lens for an illumination device, including an incident surface, an emergent surface, and a reflective surface connected between the incident surface and the emergent surface. The lens includes a first axis as an optical axis of the lens, a second axis perpendicular to the first axis and extending in a longitudinal direction of the lens, the first axis and the second axis defining a symmetrical surface of the lens, and a third axis perpendicular to the symmetrical surface, a first portion of light from a light source is incident upon the incident surface, refracted by the emergent surface, and then emerges to form a first light beam, and a second portion of light from the light source is incident upon the incident surface, reflected by the reflective surface, refracted by the emergent surface, and then emerges to form a second light beam.
