A double-ended socket system for safely and easily seating a double-ended lamp is disclosed. The system has two socket assemblies spaced a distance corresponding to the length of a double-ended lamp. Each socket assembly has a housing with a recess that houses a cylindrical socket for receiving a lamp end that rotates between a disengaged orientation and an engaged orientation. The housing has an attached electrical connector connected to a power source. The socket has another attached electrical connector that contacts the electrical connector of the housing only when the socket is rotated to the engaged orientation, thus eliminating the electrical shock hazard of conventional double-ended socket systems. The lamp may be removed only while in the disengaged orientation. A user may install a double-ended lamp into the socket system by use of only one hand. A method of use of a double-ended socket system is also disclosed.

An elongate tubular lighting assembly having a body with a length between spaced first and second ends. The tubular lighting assembly has an elongate heat sink and a light source comprising LED emitters and first and second connectors respectively at the first and second body ends for securing the lighting assembly to a light fixture. The first connector has cooperating first and second parts having first and second surfaces. The first and second connector parts are configured so that the first and second surfaces are placed in confronting relationship to prevent separation of the first and second connector parts with the body in an operative state as an incident of the first connector part moving relative to the second connector part from a position fully separated from the second connector part in a substantially straight path that is transverse to the length of the body into an engaged position. The first connector part has conductive power and ground pins and the second connector part has conductive power and ground terminals for connecting with an external power supply and providing a grounding path for components of the lamp. The power and ground pins of the first connector part are configured to engage the power and ground terminals of the second connector part as an incident of the first connector part moving relative to the second connector part into the engaged position. A sleeve connector is also provided for mounting a non-power end of a linear LED lamp to a light fixture.

The present invention relates to an electric connector and an illuminating device comprising this electric connector, wherein the electric connector comprises a housing and an end cap connected to the housing, wherein an conductor which can be connected to a power supply is arranged in the end cap, wherein the conductor comprises a stationary part and a movable part, wherein the conductor is rotatable relative to the housing along with the end cap from a first position to a second position, wherein the movable parts at least partially retract into the stationary part in the first position, and at least one movable part extends out of the stationary part in the second position so as to be in electric connection with a power consumption component arranged in the housing.

The present invention is directed to a linear LED light fixture system. The system includes a LED light engine with curved or angled elbow bracket or end pieces having clip ends that fit into and secure within matched holder apertures of a linear light fixtures. The LED light engine preferably includes a linear housing with an internal array of LEDs and a LED driver circuit that electrically couples to power source through the angled elbow bracket or end pieces. The system is used in new linear LED light fixtures and or is used for converting fluorescent linear light fixtures into linear LED light fixtures.

The present disclosure relates to a G24 plug adaptor for use in retrofitting a traditional plug-in energy-saving luminaire, the traditional plug-in energy-saving luminaire initially adapted to receive a traditional energy-saving lamp, to be compatible with a non-traditional panel lamp such as, but not limited to, an energy-saving LED panel lamp. The G24 plug adaptor comprises a G24 plug base comprising a plurality of contact pins, an electrical connector adapted to couple to the non-traditional lamp, and an electrical supply line connecting the G24 plug base to the electrical connector. A method of retrofitting a traditional energy-saving luminaire to be compatible with a non-traditional panel lamp by using the G24 plug adaptor, the method comprising removing a reflector of the traditional plug-in energy-saving luminaire, is also disclosed herein.

A lighting device includes an illumination part, and a power connection part adapted to transfer outside power to the illumination part and for preventing an electrical short circuit. The power connection part includes at least two power connectors which are separated from each other and into which the external power is transferred and an insulator provided between the at least two power connectors and coupled with the at least two power connectors.

An adaptor, a light source device using the adaptor, and a lighting apparatus using the adaptor are provided. The adaptor includes a main body, a protruding part, and an operating component.
