Abstract: A light-emitting diode includes a semiconductor light-emitting stack and a distributed Bragg reflector (DBR) structure. The semiconductor light-emitting stack has a first surface and a second surface opposite to each other. The DBR structure is disposed on one of the first surface and the second surface of the semiconductor light-emitting stack, and includes at least one set of first light-transmitting layers and at least one set of second light-transmitting layers stacked on each other in the first direction. The first light-transmitting layers has interface roughness greater than that of the second light-transmitting layers.

Abstract: The invention teaches a press-button type display indicator for golf club protector, comprising an enclosure having a marker display window and a connective device to engage with the golf club protector; a rotation wheel that can be rotated intermittently and a first half shaft and a second half shaft serving to supply the rotation of the rotation wheel set inside of the enclosure, wherein the first half shaft and the second half shaft are hollow tube shafts, and are located at the two sides of the rotation wheel, respectively; a pressing apparatus connected to the rotation wheel is disposed at one side of the rotation wheel; and a plurality of different markers is distributed along the circumferential direction of the rotation wheel, and is displayed orderly through the marker display window on the enclosure when rotating the rotation wheel intermittently.

Abstract: Taught herein is an identification device for golf club head covers comprising an outer shell having a front cover and a back cover; a window for displaying identifying indicia disposed on said front cover; a disk bearing a plurality of identification indicia; means for rotating the disk intermittently so that the identifying indicia are displayed through the window, one indicium at a time, the means being disposed within said outer shell; and means for connecting the identification device to a golf club head cover. Since a plurality of different identification indicia can be displayed at a push of a button, a convenient and easy to use identification device for golf club head covers is realized.

Abstract: The invention teaches a tumble-type display device for golf club protector, comprising an enclosure having a connective member to connect with the golf club protector; said enclosure comprising a front cover having a marker display window set thereon and a back cover; a disk capable of rotating intermittently and a tumbling apparatus and a non-return apparatus acting on said disk disposed inside of said enclosure; and a plurality of markers marked and distributed along the circumferential direction of the disk. When rotating the disk intermittently, the different markers are displayed orderly through the marker display window, and only one marker is displayed at one time.

Abstract: The invention teaches a tumble marker indicator for golf club protector, comprising an enclosure having a marker display window and a connective device to engage with the golf club protector; a rotation wheel that can be rotated intermittently and a rotating shaft engaged with the rotation wheel are set inside of the enclosure; a tumbling apparatus connected to the rotation wheel is set at one side of the rotation wheel; a non-return apparatus to avoid the back rotation of the rotation wheel is set at the other side of the rotation wheel; and a plurality of different markers distributed along the circumferential direction of the rotation wheel, which can be displayed orderly through the marker display window on the enclosure when rotating the rotation wheel intermittently.

Abstract: The present invention teaches a golf club protector capable of carrying one or more golf accessories, such as a golf ball, a tee holder, or a grass trimmer, comprising: an animal-like body having a mouth for receiving a golf club head, said mouth comprising an upper portion and a lower portion; a cavity for receiving one or more said golf accessories, said cavity being disposed in said mouth; and means for joining said upper portion and said lower portion. The means for joining are, for example, one or more magnet(s), a magnetic tape, or a zipper. The upper portion and the lower portion, when taken together, form an open state or a closed state. The cavity for receiving the golf accessories comprises one or more holding member(s) such as a narrow clamp, a wide clamp, and a holding pocket.
