摘要： A particle detector includes 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 photoelectric surface. A particle deposited on the photoelectric surface of the metal layer changes the near-field surface plasmon resonance photons to far-field scattered light. The particle detector further includes a scattered light detecting unit, provided above the photoelectric surface of the metal layer, for detecting the far-field scattered light.

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： 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.
