Abstract: The present invention is an optical device that is not axially symmetric; comprising of a lampshade at least; wherein, an optical unit mounted to the transverse of lampshade, an illuminant mounted inside the lampshade where corresponding to the center of inner lateral to the optical unit; meanwhile, the optical unit is geometrically structured in a non-axisummetric configuration while the optical unit is fitted a reflector with plurality of cascades along the ring at the external lateral; thus, a refraction or reflection against the light emitted from the illuminant can be performed when permeating through the optical unit that beams a strip light pattern achievable.

Abstract: A light condensing structure for illuminating device includes a lamp shade; an optical unit located at an open end of the lamp shade and provided on one of two opposite sides with a plurality of concentric annular light condensing sections, each of which has an upward tapered cross-sectional shape; and a light-emitting element mounted in the lamp shade to face toward the other side of the optical unit. Divergent lights from the light-emitting element can be totally reflected (refracted) by the light condensing sections of the optical unit, so that an increased illuminating brightness can be achieved for the illuminating device.

Abstract: A candle lighting type reflective lampshade comprises a lampshade main body being made with a reverse cone body on the upper half thereof and a cover layer on the inner cone surface thereof, wherein the cone surface forming a pair of symmetrical parabolic curves includes a ring type aperture on the top thereof thereby allowing the underside light source to achieve secondary full reflection; the base of lampshade main body comprises a plurality of inclined surfaces being ringly peripherally installed thereon and being installed with a plurality of lamp source bases below the inclined surfaces, while the light source is effectively controlled by the lamp source base to beam the light on the cone top portion of the reverse cone body so as to fully reflect each light beam and to achieve uniform dispersion of the light source.

Abstract: The preferred embodiment the invention proposes pertains to a light source system structure, claimticularly referring to a multiple light-source source packaging structure, which is comprised of a surface wrapped with a multiple number of packagers, and inside the packagers is a placement space, and the surface of the packager is of a smooth surface; a micro-Fresnel lens unit, which is mounted in the placement space, and the micro-Fresnel lens unit is comprised of a multiple number of encircling micro-Fresnel lenses, with a concave slot located at the center of the encircling micro-Fresnel lens unit and a light source mounted beneath the concave slot, where the light created from the light source can be deflected and projected through the micro-Fresnel lens unit, through which to further control the angle of each light beam, together with a circuit control switch linked to the light source to further control the distance of light projection from the multiple number of packagers, enabling the distance of proje
