Abstract: A semiconductor light-emitting device includes a semiconductor stack including a first semiconductor layer and a second semiconductor layer; a first reflective layer formed on the first semiconductor layer and including a plurality of vias; a plurality of contact structures respectively filled in the vias and electrically connected to the first semiconductor layer; a second reflective layer including metal material formed on the first reflective layer and contacting the contact structures; a plurality of conductive vias surrounded by the semiconductor stack; a connecting layer formed in the conductive vias and electrically connected to the second semiconductor layer; a first pad portion electrically connected to the second semiconductor layer; and a second pad portion electrically connected to the first semiconductor layer, wherein a shortest distance between two of the conductive vias is larger than a shortest distance between the first pad portion and the second pad portion.

Abstract: A control system for cordless blinds includes at least one wrapping unit, at least one rod and a transmission cord which is wrapped to the at least one rod. Two cords are wrapped to the at least one rod and extend through the slats and are fixed to the bottom bar connected to the lower end of the slats. Two frames are fixed in the top box and located beneath the at least one rod. The frames each include at least one notch so as to support the at least one rod. One of the two frames includes first and second pulleys and the other frame includes a third pulley. The transmission cord and the two cords are wrapped to the pulleys respectively, such that the transmission cord and the two cords are operated smoothly. The number of the rod and the frames can be added as needed.

Abstract: A curtain assembly a top box and a first curtain and a second curtain are connected to the scrolling mechanism in the top box. The second end of the first curtain is connected to the second end of the second curtain by multiple securing units which are fixed to a transverse bar on the second curtain. Multiple restriction members each include a clamping part and an elongate plate which extends perpendicularly from the clamping part. The second curtain includes multiple transverse sections separated by section rods which extend through passages defined transversely in the second curtain. Each passage communicates with two notches which are located corresponding to two sides of the first curtain. The clamping parts of the restriction members are inserted through the notches and clamp the section rods, and the elongate plates are located outside of the first curtain.

Abstract: A shower curtain assembly includes a shower curtain having multiple slits defined between the through holes and the top edge of the shower curtain. Multiple ring units are connected to the shower curtain and located corresponding to the connection areas respectively. Each ring unit includes a first part and a second part. The first part is a ring-shaped part with a gap defined radially therethrough and the gap is located corresponding to the slit. The second part is a substantially horseshoe-shaped part having a first end and a second end. The first end is bent to form a first closing portion and the second end is bent to form a second closing portion which is overlapped on the first closing portion so as to close the second passing hole. A shower rod separates the slits, the gaps and the overlapped closing portions when installed to the shower curtain.

Abstract: A shower curtain ring assembly includes multiple curtain ring units each have a ring and a clamping portion extending from the ring, the shower rod extends through the rings. Each clamping portion includes two extensions with an entrance defined between two distal ends of the two extensions and a slot is defined in the two extensions so as to accommodate the first and second parts and the shower curtain. The shower curtain includes first and second collars connected thereto and the first and second collars are engaged with a periphery of the passage. The first and second collars push the two extensions outward so as to be retained between the passage between the extensions. Therefore, the shower curtain can be connected to or removed from the shower rod without removing the shower rod from the rings.
