Abstract: A thin-type spherical lens, fabricated according to the result of the virtual procedures of removing the portion of each of a plurality of lens bodies with different radii of curvature of light-exiting faces, which corresponds to a spherical surface with the optical axis of the thin-type spherical lens as its central axis, and assembling the preserved portions thereof to form a plurality of grooves as the light-exiting faces, which are equivalent to the grooves of the conventional Fresnel lens, wherein the depths or the widths of the plurality of grooves are different, and the curvature radii of the plurality of light-exiting faces are also designed to be different so that the lights emerging from the plurality of light-exiting faces are all focused on an identical point. The present invention can, as compare to the conventional approach, reduce the lens thickness when the radius of the apertures on the lens increased.

Abstract: The invention discloses a motion detector that includes a casing, a sensor and a signal deflector. The casing has a lens array around an external periphery of the casing and an installation space inside the casing for installing the sensor and the signal deflector. The sensor includes a sensing unit and a signal processing unit electrically connected with each other. The signal deflector is installed between the sensor and the lens array, and the signal deflector includes a plurality of elliptic concave lenses for reflecting lights incident from different directions to the sensing unit by the focusing characteristics of the elliptic concave lenses, so as to broaden the scope of applications.

Abstract: The invention discloses an improved reflective mirror structure used together with a sensor, and the reflective mirror includes at least one elliptic curved surface, and the elliptic curved surface has a first focus and a second focus, and the sensing area of the sensor is located at the second focus. With the characteristic of having dual foci on the elliptic curved surface, the light beams incident from different directions are passed through the first focus of the elliptic curved surface and then reflected from the elliptic curved surface towards the second focus and received by the sensor, and such design makes the detecting range of the sensor larger than 180 degrees.
