摘要： A light emitting apparatus with a combination of a plurality of LED chips and a phosphor layer is provided and can be configured to significantly reduce variations in chromaticity and luminance. The plurality of semiconductor light emitting devices (LED chips) are disposed with a gap therebetween, and the phosphor layer is formed on the upper surface thereof to bridge over the gaps between the LED chips. The phosphor layer may be uniform in thickness, but can be less in thickness over the gaps between the LED chips than on the upper surface of the LED chips. The phosphor layer can be continuously formed on the upper surface of the array of the chips with no phosphor layer present in between the chips. This configuration allows for reducing variations in luminance and chromaticity which may result from the gaps or the phosphor layer present in between the gaps.

摘要： A semiconductor light source apparatus can emit various color lights having a substantially uniform color tone and high brightness. The semiconductor light source apparatus can include a radiating substrate, at least one phosphor layer disposed on the radiating substrate and a semiconductor light source emitting blue light. The at least one phosphor layer can be composed of at least one of a glass phosphor and a phosphor ceramic. The light source can be located adjacent the phosphor layer so that the blue light having high brightness can be efficiently reflected on the radiating substrate via the phosphor layer while preventing the blue light from a mirror reflection on the phosphor layer. Thus, the disclosed subject matter can provide a semiconductor light source apparatus that can emit various uniform color lights having high brightness and a lighting unit using the light source apparatus, which can be used for general lighting, vehicle lighting etc.

摘要： The disclosed subject matter includes reliable semiconductor light-emitting devices having a favorable light distribution using an LED chip, which can emit light having a different color as compared to that emitted directly by the LED chip. The semiconductor light-emitting device can include an LED chip having an electrode, a phosphor layer located on the LED chip except for the electrode, a bonding wire connected to the electrode, and a light-reflecting resin. The light-reflecting resin can be disposed on a light-emitting surface that is exposed around the electrode and on the electrode including the bonding wire, and can prevent the LED chip from exhibiting a leak of light that is not wavelength-converted via the phosphor layer, while increasing light that passes through the phosphor layer. In addition, the light-reflecting resin can protect the bonding wire from vibration, etc. Thus, the disclosed subject matter can provide reliable semiconductor light-emitting devices having high brightness without substantial color variability and that can emit various colored light(s).

摘要： A particle detector comprises a light source, and a metal layer having an incident/reflective surface and a photoelectric surface opposing the incident/reflective surface. Incident light from the light source reaches the incident/reflective surface to excite near-field surface plasmon resonance photons at the photoelectronic surface. A particle deposited on the photoelectronic surface of the metal layer changes the near-field surface plasmon resonance photons to far-field scattered light. The particle detector further comprises a unit, provided above the photoelectric surface of the metal layer, for detecting the far-field scattered light.
