An illumination device (e.g., an electric candle, etc.) generally includes a housing, a light source, and a pendulum supporting the light source. The pendulum is pivotally coupled to the housing and is configured to move the light source relative to the housing. The illumination device also includes a control unit for providing power to the illumination device and for controlling operation of the light source, and at least one wire electrically connecting the light source to the control unit. The at least one wire has a diameter of about 0.5 millimeters or less to avoid impact of the wire to the pivotal movement of the pendulum.

A mounting base of a lamp, a lighting assembly, and a lamp are provided. The mounting base is configured to be in detachable connection with a plurality of lighting assemblies, the mounting base includes at least one mounting portion and a plurality of first electrical terminals fixed on the mounting portion, and the plurality of first electrical terminals on each mounting portion are configured to be in plug-in fit with a plurality of second electrical terminals of the lighting assemblies in one-to-one correspondence. The plurality of first electrical terminals are configured to supply power to the plurality of lighting assemblies when plugged in with the plurality of second electrical terminals.

The present invention discloses a lamp holder for fastening a lamp, including a base and a movable pole. A mounting groove is disposed on the base. A mounting opening is disposed at a end of the mounting groove. Two fastening poles extend upwardly on both sides of the mounting opening. Notches are separately disposed on sides facing each other of the two fastening poles. Two elastic parts are disposed at the free end of the movable pole. Protrusions matching the notches are formed on the two elastic parts. During mounting of a lamp, the lamp holder for fastening a lamp can enable real-time observation of the lamp's pin to avoid pin bending caused by an improper pin mounting position, and is more convenient and labor-saving during use.

A decorative lamp includes a flexible mounting shell with a first end, a second end opposite the first end, a through hole extending through the first and second ends, a ridge extending into the through hole, and a first plurality of grooves. A light emitting body is positioned at least partially within the mounting shell, and the light emitting body extends through the first end of the mounting shell. A tail plug is positioned at least partially within the mounting shell adjacent the second end, and the tail plug includes a second plurality of grooves. The first plurality of grooves and the second plurality of grooves are aligned to form tracks configured to receive wires coupled to the light emitting body, and an outer surface of the mounting shell includes a stepped structure.

A decorative lamp includes a shell and a light emitting body. The shell includes a first end, a second end opposite the first end, and a through hole extending through the first and second ends. The light emitting body is positioned in the through hole of the shell. A first portion of the light emitting body extends into the through hole, and a second portion of the light emitting body extends out of the shell. An outer side wall of the shell includes at least two stepped structures.

A light-emitting unit, having a substrate; a first light-emitting body formed on the substrate, and having a first longer side and a first shorter side; a second light-emitting body formed on the substrate, and having a second longer side and a second shorter side which is parallel to the first longer side; a third light-emitting body formed on the substrate, having a third longer side and a third shorter side which is parallel to the first longer side, and electrically connected to the first light-emitting body and the second light-emitting body; a first electrode covering the first light-emitting body and the second light-emitting body, and electrically connecting to the first light-emitting body; a second electrode separated from the first electrode, and covering the second light-emitting body without covering the first light-emitting body; and a transparent element enclosing the first light-emitting body, the second light-emitting body, and the third light-emitting body.

A retrofit light emitting diode (LED) lamp is provided for replacement of ballast driven fluorescent lamps. The retrofit LED lamp comprises a plurality of light emitting diodes. The plurality of light emitting diodes is mounted on a metal core printed circuit board (MCPCB). A PCB circuit is provided for driving the plurality of LEDs that further comprises a bridge rectifier made of a schottky diode.

A luminaire (10) is disclosed comprising a housing (20) having a metal section (21) and incorporating an electrical component arrangement including a printed circuit board (40) having a first major surface carrying at least one light engine and a second major surface opposite the first major surface; a heatsink (30) exposed within said metal section, the heatsink having a further major surface facing the second major surface; an electrically insulating layer (50) in between the further major surface and the second major surface and having a margin (51) extending beyond each of the second major surface and the further major surface by a minimum width (W), said margin being separated from the metal section by an air gap having a minimum height (H); and at least one electrically insulating fixing arrangement (90, 100, 110) extending through the printed circuit board and the electrically insulating layer securing the printed circuit board to the metal section.

A lighting apparatus comprises: a board, a plurality of light-emitting units disposed on the board, and a package structure enclosing all of the light-emitting units and having a volume less than 5000 mm3. The lighting apparatus has a light intensity greater than 150 lumens.

A lamp device with changeable lamp socket includes a light tube, a light source plate received in the light tube, and two lamp sockets locked with two ends of the light tube. The lamp socket includes a first tubular body, a first covering plate, and two conductive plugs. The lamp device further includes two adapter covers detachably locked on the lamp sockets. Each adapter cover includes a second tubular body, a second covering plate, and a conductive component.
