Patent number: 9586286Abstract: The invention provides an apparatus for fabricating a periodic micro-pattern by laser beams. The apparatus includes an ultrafast laser light source configured to generate an output laser beam. A diffraction optical element is configured to divide the output laser beam into a plurality of diffractive laser beams. A confocal system is configured to focus the plurality of diffractive laser beams on a focal point, so that the plurality of diffractive laser beams produces an interference light beam with interference phenomena.

Patent number: 8931915Abstract: The present invention provides an anti-opening structure of a lighting device. A recess area preset at a lower portion under an external thread section formed at a lighting source main body is disposed with a restraining member. A hole preset at a lower end of an internal thread section, formed inside of a cap, combines with a nut to allow a screw to be screwed out through the nut outwards the cap. The screw is formed with a projecting circular portion. The cap screwing into the end of the lighting device main body is configured with the anti-opening structure. The screw is screwed into the restraining member by inserting an end of a tool into the screw protruding out of an outside of the cap. The screw is unable to screw in when the projecting circular portion abuts against the restraining member to provide the cap with the anti-opening structure.Type: GrantFiled: September 18, 2013Date of Patent: January 13, 2015Assignee: Day Sun Technology Ltd.Inventor: Shih-Hao Wang

Publication number: 20140198492Abstract: A waterproof-breathable structure for a flashlight includes a housing and a ventilative plug. The housing is penetrated by a hole with one or more chamfered segments, and the ventilative plug has an outer diameter greater than the hole to be closely fit therein. The ventilative plug has a capping portion, an abutting flange extending from an outer part thereof, and a rim extending from an inner part thereof. Thereby, inner pressure generated in the flashlight due to battery oxidation over time is allowed to escape through an interval formed between an inward retracted periphery of the ventilative plug and the chamfered segments formed at the inner periphery of the housing hole, while the ventilative plug closely fit in the hole of the housing of the flashlight serves to effectively prevent external moisture from incursion.Type: ApplicationFiled: January 15, 2013Publication date: July 17, 2014Inventor: Shih-Hao Wang
