  • Patent number: 9147814
    Abstract: A semiconductor light-emitting device and a method for manufacturing the same can include a wavelength converting layer located over a semiconductor epitaxial layer in order to emit various colored-lights including white light. The light-emitting device can include a semiconductor chip substrate configured not to transmit light emitted from the epitaxial layer and mounted on a mounting board, and a transparent resin layer located between the wavelength converting layer and the epitaxial layer mounted on the semiconductor chip substrate so as to extend from a side surface of the wavelength converting layer towards a substantially edge portion of the semiconductor chip substrate. The semiconductor light-emitting device can be configured to improve a color variability of a mixture light emitted from the device by using the transparent resin layer and the wavelength converting layer, and therefore can emit the mixture light having a substantially uniform color tone from a small light-emitting surface.

  • Patent number: 8735926
    Abstract: A semiconductor light emitting device which has a wavelength converting part on a semiconductor film and can eliminate unevenness in emission color without a reduction in light output. The semiconductor film includes a light emitting layer. The support substrate is bonded to the semiconductor film via a light-reflecting layer and has a support surface supporting the semiconductor film and edges located further out than the side surfaces of the semiconductor film. The light-shielding part covers the side surfaces of the semiconductor film and part of the support surface around the semiconductor film in plan view. The wavelength converting part contains a fluorescent substance and is provided over the support substrate to bury the semiconductor film and the light-shielding part therein. The wavelength converting part has a curved surface shape in which its thickness increases when going from the edges toward the center of the semiconductor film.
