    摘要： A lighting fixture includes: a base; a plurality of optical sources attached on an upper surface of the base to emit light; a heat spreader attached to the base to radiate heat emitted from the plurality of optical sources; and a light diffusion lens disposed on the upper surface of the plurality of optical sources to refract light emitted from the plurality of optical sources and to increase an irradiation angle of light. In the lighting fixture, an irradiation angle of light emitted from an optical source is close to that of a general electric-light bulb and thus a light distribution characteristic of the lighting fixture may be improved.

    摘要： An omnidirectional semiconductor light emitting device lamp has a light distribution characteristic having a large range similar to that of a general incandescent lamp. The semiconductor light emitting device lamp includes a light emitting device for emitting light in all directions and reflection plates arranged at a front surface and a lateral surface of the light emitting device. The light emitted from the light emitting device is reflected from the reflection plate located at the front side and the reflection plate located at the lateral side and emitted to a rear side of the light emitting device. A reflection film is formed on all exposed portions of a surface of the substrate on which the light emitting device is mounted.

    摘要： When it is intended to realize a lens having a large NA with one lens, an adjustment precision between both surfaces of the lens is very strict. Accordingly an objective lens having an NA of 0.8 or more was usually realized by two lenses. However, a working distance is small, and collision of the objective lens with a disc is apt to occur. A coma corrector for compensating coma caused by decentering of both surfaces in realizing the high NA lens with one lens is added. However, in this case, astigmatism occurs when the objective lens decenters from the coma corrector relatively accompanied with a tracking operation. The objective lens and the coma corrector are fixed to a mirror barrel so as to be unified with each other, and driven by a two-dimensional lens actuator. With such a constitution, decentering of the objective lens and the coma corrector does not occur, and hence astigmatism does not occur.
