PROBLEM TO BE SOLVED: To provide an ultraviolet light emitting diode solidification device.SOLUTION: This ultraviolet (UV) light emitting diode (LED) solidification device is used for solidifying UV-cured gel on nails, and includes a housing and a UVLED lighting assembly covered on the housing. The housing has a lighting hole, radiates UV lights emitted from a UVLED light source on the UVLED lighting assembly, and is controlled by a combined timer controller and a current adjuster. The UVLED lighting assembly has an optical unit, introduces and limits the UV lights to be radiated on the lighting hole of the housing, provides a lighting focus, and avoids the UV lights from leaking outside the housing. The UVLED light source preferably has a short wave length, and preferably, a current provided to the UVLED light source by a power supplier is automatically controlled by the timer controller and the combined current adjuster. A switch for electrical connection is turned on within a predetermined time, so as to radiate the UV lights to the lighting hole of the housing.

PROBLEM TO BE SOLVED: To reduce inferior image formation due to lens inclination. SOLUTION: The lens fixing structure has a slot used for lens setting and fixing. The slot is formed by a first groove wall disposed on a housing and a second groove wall arranged on the housing in parallel to the first groove wall. Further, a light transmission rod which is positioned in parallel with the second groove wall on the one side of the slot and has a light beam emitting surface is disposed. The lens fixing method is provided with the steps of: reducing a release angle which is positioned on the slot side of the second groove wall to 0° on the lens fixing structure; raising the height of the second groove wall so that the height of the second groove wall is lower than the height of the light beam emitting surface or is equal to the height of the light beam emitting surface; and respectively filling fixation glue between the first groove wall and a lens and between the second groove wall and a lens so that the heights of spot glue on both sides coincide with each other.

Abstract:
PROBLEM TO BE SOLVED: To provide a condensing structure in which a light source is collected and derived to a scanned area. SOLUTION: This structure is constituted by combining reflecting faces 832 and 831 shaped like circular-arc and elliptic circular-arc, and an anti-optical piece is attached or anti-optical materials are applied to the surface so that the light intensity and light uniformity of a face to be scanned can be improved. When a light source 82 is made to emit lights, the rays of light are directly made incident to the face to be scanned in a fixed light emission area, and the originally invalid rays of light in the other azimuth are also collected by the reflecting faces 832 and 831 shaped like circular-arc and elliptic circular-arc, and the rays of light are derived to the required area to be scanned, and then made to develop themselves on a photosensitive element(CCD or CMOS) 85 by the area to be scanned.

PROBLEM TO BE SOLVED: To provide an optical image scanner having an adjustable dilation ratio, and also to provide an adjusting method of the dilation ratio. SOLUTION: The optical image scanner includes a transparent object 3 to be disposed within an object distance D or an image distance d. Correction and reduction of the object distance D or the image distance d are accurately established without changing positions of a lens 1 and an electric optical element 2 because a refractive index of the transparent object 3 is larger than that of air.
