Abstract: The spot downlight apparatus includes a power head, a tubular body, a back cover, a light source plate, a heat sink, in insulation layer and a lens module. The power head is connected to an external power source. The power head has a rotation structure. The tubular body is made of metal material. The tubular body has a front opening and a back opening. The tubular body is fixed to the rotation structure so as to be manually rotated with respect to the power head. The back cover is fixed to the back opening of the tubular body. The light source plate is mounted with a LED module. The heat sink has a platform holder and a sidewall. The lens module has a top part and a bottom wall.

Abstract: A lighting apparatus includes a driver configured to convert external power to a driving current, a light source connector with top and bottom portions separated by a distance, and a light source provided on a light source plate including a conductive patch. The light source plate is held between the top portion and the bottom portion, such that the driving current is supplied to the light source plate by the conductive path routed via the light source connector.

Abstract: A COB illuminating device includes a light source component, a control module, and a base plate component. The light source component includes multiple illuminating sets that are electrically coupled in series. The control module includes multiple control terminals, an input control terminal, an output control terminal and a constant current control unit. The multiple control terminals are respectively and electrically coupled to intersections between the multiple illuminating sets. The input control terminal is electrically coupled to a head illuminating set. The output control terminal is electrically coupled to a tail illuminating set. The constant current control unit is electrically coupled to the multiple control terminals, the input control terminal and the output control terminal. Besides, the constant current control unit activates a dynamic number of illuminating sets starting from the head illuminating set.

Abstract: A lighting apparatus includes a driver, a light source connector, and a light source plate. The driver is used for converting an external power to a driving current. The light source connector structure has a top portion and a bottom portion. The top portion and the bottom portion keep a distance and clip the light source plate between the top portion and the bottom portion. The driving current is supplied to the light source plate with a conductive path routed via the light source connector.
