  • Publication number: 20170254948
    Abstract: A mold which is made of a porous heat-resistant material comprises a first surface and a second surface opposite to the first surface. A plurality of light guide spots are formed on the first surface. The light guide spots are light guide spots. The first surface is a smooth polished surface, the mold enables direct manufacture of light guide plates for less heat expended.

  • Publication number: 20150311000
    Abstract: A dye-sensitized solar cell package including a lower substrate, a glass layer, an upper cover arranged series. The glass layer is between the upper cover and the lower substrate. Two conductive metal layers are respectively formed on the surface of the upper cover and the lower substrate which are oriented toward the glass layer. The upper cover, the glass layer and the lower substrate are welded together by laser. The invention also provides a method for manufacturing the dye sensitized solar cells package.

  • Patent number: 6280809
    Abstract: A luminous disk is disclosed in this invention. The luminous disk comprises a disk lamination and a light emitting lamination. The disk lamination at least comprises a substrate and a metallic reflecting layer. The light emitting lamination at least comprises an electroluminescence section having a first side plane and a second side plane, and a biasing section for applying an external electrical signal onto the first and the second side planes so as to make the electroluminescence section luminesce. Basing on the above structure, a new disk having a redoubled effect is available.

  • Patent number: 6254260
    Abstract: A car cabin light device capable of storing digital data is disclosed. The car cabin light device comprises a switch, a light emitting element for emitting light under a biasing of an external source, and a socket provided in a car cabin for detachably receiving the light emitting element and conducting the external source thereto. The light emitting element is constructed by a luminous disk having a first surface for accessing data and a second surface for luminescing. The luminous disk comprises: a data recording lamination located at the side of first surface for storing digital data; a light emitting lamination having two side planes and located at the side of second surface; and a biasing lamination for receiving the external source and applying it to the two side planes of the light emitting lamination for emitting light.
