Abstract: An LED illuminating showcase includes a frame unit and a lighting unit. The frame unit includes bottom and top seat covers, and a transparent tubular shell extending from the bottom seat cover to the top seat cover and defining a display space with the seat covers. The lighting unit includes opposite terminal subunits respectively disposed in the seat covers, a connecting bar connected fixedly to an inner surface of the tubular shell, having two ends that abut respectively against the seat covers, and that are connected respectively and electrically to the terminal subunits, and an LED module embedded in the top seat cover for illuminating the display space.

Abstract: A display stand includes a frame body and several illuminating support plate units. The frame body has several spaced-apart plate-mounting portions, and several power supply portions respectively adjacent to the plate-mounting portions. Each illuminating support plate unit includes a plate body coupled removably to one plate-mounting portion, an illuminating unit mounted on the plate body, and an electric connecting unit having a base portion that is embedded in the plate body, and an electric connecting portion that is disposed within a range defined between extensions of upper and lower surfaces of the plate body, and that is connected electrically to a corresponding one of the power supply portions.

Abstract: Disclosed herein is a heat dissipation composite having a metal substrate, a metal bonding layer, and a ceramic layer. The metal bonding layer has a melting point lower than that of the metal substrate and is formed on the metal substrate through metal-to-metal bonding. The ceramic layer is composed of ceramic powders and is covered on and bonded to the metal bonding layer opposite to the metal substrate.

Abstract: An LED bulb includes a heat dissipating seat, a circuit board, a plurality of LEDs mounted to the circuit board, and a light reflecting unit. The heat dissipating seat includes a surrounding wall and an end wall connected to one end of the surrounding wall. The circuit board is coupled to the end wall and has a first securing unit. The light reflecting unit has a main wall and a bottom wall. The main wall extends from the circuit board, has an inner diameter gradually increasing in the direction away from the other end of the surrounding wall, and is disposed for reflecting light emitted from some of the LEDs. The bottom wall is surrounded by and connected to the main wall, and has a second securing unit fastened to the first securing unit.

Abstract: A spotlight device includes a support member, a pivot joint mechanism, and a lighting member. The pivot joint mechanism includes a first pivot connection part provided on the support member, and a second pivot connection part connected rotatably to the first pivot connection part. The lighting member includes a base plate on which the second pivot connection part is mounted, a light emitting component mounted on the base plate, and a light directing cap extending from a periphery of the base plate and cooperating with the base plate to define a receiving space. The light emitting component is disposed in the receiving space.

Abstract: A light bulb includes a bulb base, a light holder, a plurality of light emitting elements, and a bulb shell. The bulb base has a connection part and an engaging part disposed opposite to each other. The light holder includes a surrounding wall connected to the bulb base at the engaging part, and an end wall connected to the surrounding wall. The light emitting elements are disposed on the surrounding wall and the end wall and are connected electrically to the bulb base. The bulb shell includes a light-transmissive shell body that engages the engaging part of the bulb base, and has a receiving space defined by the shell body and into which the light holder extends.
