  • Patent number: 7824937
    Abstract: A method for manufacturing a solid element device, which comprises providing a glass-containing Al2O3 substrate (3) having a GaN based LED element (2) placed thereon, setting a P2O5—ZnO based low melting point glass in parallel with the substrate, and carrying out a press working at a temperature of 415° C. or higher under a pressure of 60 kgf in a nitrogen atmosphere. Under these conditions, the low melting point glass has a viscosity of 109 poise, and is adhered via an oxide formed on the surface of the glass-containing Al2O3 substrate (3). A solid element device manufactured by the above method can be manufactured through a glass sealing working at a low temperature and also has a highly reliable sealing structure.

  • Patent number: 6791116
    Abstract: In a light emitting diode, a scattering material-containing light guiding/scattering layer is provided which directly receives light emitted from a light emitting element. The scattering material contained in the light guiding/scattering layer irregularly reflects and scatters the incident light. The scattered light is led to a fluorescence emitting layer formed of a transparent binder containing a phosphor material. The probability of incidence of light having high optical density, which has been emitted from the light emitting element, directly to the phosphor material contained in the fluorescence emitting layer is lowered, and light can be radiated from the whole fluorescence emitting layer. Therefore, uniform light having a desired color can be radiated with high efficiency from the light emitting diode.
