    摘要: A white LED illumination device can include a white LED that has unevenness in tone and is used as a light source. The white LED illumination device can emit white light with high color rendering properties without unevenness in tone and can include the above noted white LED located adjacent an optical lens. The white LED and optical lens can be arranged so that the optical axes of both are substantially aligned with each other. The white LED can include an LED chip which emits light having a peak wavelength in the blue wavelength range and a fluorescent material which can be excited by the light emitted from the LED chip to emit yellow or yellowish green fluorescence (i.e., complementary colors to blue) by use of wavelength conversion. The optical lens can have a recessed light incident surface having an opening, a light emitting surface, and a totally reflective surface positioned between the light incident surface and the light emitting surface. The inner bottom of the recessed light incident surface can include a convex shape having a convex surface. The light emitting surface can be composed of a convex portion having a center and a periphery that can be formed in different shapes or curvatures, and can include a flat surface surrounding the convex portion.

    摘要: A compact lighting fixture having various functions can be achieved at low cost. The lighting fixture can provide a high degree of freedom for space utilization, can provide a comfortable illumination space with designed light distribution, can be configured to require a smaller space for installation, and can have an appearance that is not so different from its surroundings. As a component constituting the illumination optical system, a polygonal frustum portion can be located at a center and can have tapered side reflecting portions. When assuming that three concentric imaginary circles have respective radii of R1, R2 and R3 (R1
