  • Publication number: 20150153487
    Abstract: A wavelength-converting device includes a substrate and a reflective layer. The reflective layer is disposed on the substrate, among which when an operating temperature of the reflective layer is higher than or equal to 130° C., the reflective layer is formed of a first metallic material, and when the operating temperature of the reflective layer is lower than 130° C., the reflective layer is formed of a second metallic material. The reflectivity of the second metallic material is higher than the reflectivity of the first metallic material at room temperature. By forming the reflective layer of the first metallic material and the second metallic material at different operating temperatures, respectively, the decay of the reflectivity is effectively avoided, the reflectivity is optimized, and the converting efficiency of the wavelength-converting device is enhanced.

  • Patent number: 8807794
    Abstract: An illumination device includes a base, a flexible circuit board disposed on the base, and a plurality of illumination units. The flexible circuit board has a plurality of first branches and at least one second branch which are connected together. Each of the first branches has a radius of curvature, and the radii of curvature of the first branches are different from or identical to one another, so that the first branches are assembled to form a curved surface. The second branch extends from one of the first branches. After the first branches are assembled, the second branch is overlapped with another first branch. The illumination units are packaged onto the first branches of the flexible circuit board. Here, the illumination units located on one of the first branches is electrically connected to the illumination units located on another of the first branches through the second branch.
