Abstract: A lamp device applicable to a display includes a lamp main body, a lamp arm component, a lamp light component and a fixing base. The fixing base is arranged on the back surface of the display, so that the lamp main body can be positioned on the fixing base to be arranged on the back surface. When the lamp arm component is rotated to the first position relative to the lamp main body, the lamp light component has a first height relative to the display, so that a first use state is provided. When the lamp arm component is rotated to the second position relative to the lamp main body, the lamp light component can be detached from the lamp arm component and then reversely installed thereon. The lamp light component has a second height different relative to the display, so that a second use state is provided.

Abstract: A high-speed ball bearing includes an outer ring, an inner ring, a plurality of balls, and a ball retainer. The ball retainer includes a plurality of pocket holes for arranging a plurality of balls, an inner circumferential surface of each of the pocket holes have a spherical surface is coaxial to the ball. A gap between an outer circumferential surface of the ball retainer and an inner circumferential surface of the ring is defined as a first gap, and a gap between the pocket hole and the corresponding ball is defined as a second gap. The first gap and the second gap have the following relationship: W2=(W1?r?)×A.

Abstract: A light-emitting diode (LED) with a bump structure on a sidewall is provided. The LED comprises a substrate, an epitaxial structure, a first conductive bump, a second conductive bump, a first extended electrode and a second extended electrode. The substrate has a top surface, a first side surface and an inclined surface between the top surface and the first side surface. The epitaxial structure is disposed on the top surface of the substrate, and comprises a N-type semiconductor layer, a light-emitting layer, a P-type semiconductor layer, a transparent conductive layer, a P-electrode and a N-electrode. The first extended electrode and the second extended electrode connect the P-electrode and the N-electrode, extend through the inclined surface, and are electrically connected to the first and the second conductive bumps, respectively. A mounting structure comprises said LED, a sub-mount and a connector mounting the LED onto the sub-mount.

Abstract: The present invention is a stamp cartridge comprising a casing having a predetermined number of channels for receiving a plurality of stampers and a holder portion for holding one of the stampers. The closed side of the casing has a plurality of holes opened therein, each hole being correspondent to one of the stampers and allowing one end of each stamper to extend into one of the holes. The end surface of one end of each stamper is flush with the external surface of the closed side of the casing. Alternatively, the end of each stamper is formed as a post which not only extends into one of the holes but also protrudes beyond the same to the outside of the casing. Therefore, the stamper can be pushed out by pressing one end of the stamper moving it along the channel of the the casing.
