摘要： An attraction plate structure of electromagnetic doorlock comprises an attraction plate positioned on a mounted body by a positioning assembly. The attraction surface has an arch portion higher than the bottom plane of 0.04 mm to 0.27 mm at a central region thereof, and the arch portion extends towards both ends to form an arc surface, so that a convex-curve surface is formed with both ends lower than the central region. The present invention uses the convex curve design of the attraction surface to produce the curved internal stress while the attraction plate is pulled. Due to the curved internal stress, the electric magnet under the normal current is able to enhance the tensile value of the electromagnetic doorlock, saving energy and enhancing the security access control.

摘要： A package structure for light emitting diode (LED) comprises a base, an LED die, an optical lens and a lens holder. The base comprises at least one holder cavity formed on its surface and at least one chase formed on its side surface. The lens holder comprises an opening, at least one holder stem and at least one wedge. The optical lens is arranged between the lens holder and the base, and also through the opening. The lens holder is fastened on the base by wedging the wedge with the chase and positioned on the base by embedding the holder stem into the holder cavity to enhance the positioning between the optical lens and the base, such that the optical lens can generate a desired light pattern. Therefore, the required time of a packaging process can be reduced, and the lens holder can be removed simply for replacing the optical lens, so the objective of changing the light pattern quickly can be achieved.

摘要： A LED array flash for cameras includes a LED array and a controller. The LED array consists of at least one LED light source with first order lens. The LED light source may be further covered with a second order lens. Thus an oblong or round distribution pattern with uniform light intensity is emitted. The controller is used to control flash modes such as low brightness continuous lighting or high brightness pulse lighting with lighting time control so as to save power and avoid overheating.

摘要： An electronic lock having a lock box arranged in the jamb and a face plate arranged in the door edge, the lock box has a brake gear with a screw sleeve arranged on a screw rod for driving the screw sleeve to displace back and forth, and by driving the rear end of the latch bolt, make the front end of the latch bolt be able to rotate inside the containing space of the lock box and go into or out of the bolt slot, and further goes into the lock slot of the face plate to achieve locking status; or the restoring of the expansion spring makes the latch bolt returned to the containing space to become unlocking status. Because the latch bolt is using the rotation to go in or out of the bolt slot and the screw sleeve and the screw rod which driving the latch bolt has the characteristic of high torque transmission, the present invention can ensure the operation stability of the lock during the locking and unlocking process.
