A system according to an embodiment of the invention may include a track and a power supply substantially contained within the track. One or more lamps may be electrically connected to the power supply. The lamp may be an HID lamp, an LED lamp, or a fluorescent lamp. The power supply may be a ballast or a transformer, and may comprise a printed circuit board with electrical power handling components on one side. The system may also include a housing which may surround the power supply.

A lamp includes an elongated tube glass light source which includes an elongated tube glass, a light emitting unit and a reflecting element, wherein the light emitting unit and the reflecting element are located within the elongated glass tube, and the reflecting element includes a reflecting layer, wherein light reaching the reflecting layer of the reflecting element is reflected and emitted from a light emission area of the elongated glass tube. The reflecting surface is formed through silver plating, the reflectivity is high and reaches 95%, and therefore the reflecting efficiency is higher, and the light energy utilization efficiency is higher. An inert gas is filled in the elongated glass tube light source to prevent the reflecting surface formed by silver plating from being vulcanized and blackened, so that the performance of the reflecting element is more durable.

The invention relates to a housing (1) for an electrical device wherein an inner surface (2) of said housing has a conductive pattern (3) providing at least one conductive track, said track being arranged to provide local electric interconnection from the housing to at least one enclosed electrical component of said electrical device and/or vice versa, wherein the conductive pattern is fixedly fastened to said inner surface (2) of said housing so that said conductive pattern will break if the housing wall is broken where the conductive pattern is fastened.

A system according to an embodiment of the invention may include a track and a power supply substantially contained within the track. One or more lamps may be electrically connected to the power supply. The lamp may be an HID lamp, an LED lamp, or a fluorescent lamp. The power supply may be a ballast or a transformer, and may comprise a printed circuit board with electrical power handling components on one side. The system may also include a housing which may surround the power supply.

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.

Apparatus and associated methods relate to a biased engagement relationship between an end cap and a support base slidably disposed within the elongate enclosure of a luminaire. In an illustrative example, the end cap may be in a fixed relationship to an open end of a translucent elongate enclosure that extends along a longitudinal axis. In some examples, the enclosure may house an LED light engine mounted to the support base. A spring may provide, for example, biased engagement relationship between the end cap and the support base over a predetermined range sufficient to prevent direct force transfer between the end cap and the support base over operating temperature ranges and/or vibration profiles. Some embodiments may dynamically damp vibrations of the support base within the enclosure, while providing for differential expansion and contraction of the enclosure and the support base, for example, over a wide temperature range.

An adapter is provided for retrofitting a lighting fixture with a light emitting diode (LED) lamp. The adapter includes a pin plate and a retaining ring. The pin plate includes at least one pin extending outward from a distal side of the pin plate. The retaining ring includes a base, at least one arm, and at least one projecting member, each having inward and outward surfaces. The at least one pin restricts movement of the adapter when the adapter is rotated to a restraining position. The at least one projecting member causes the inward surface of the at least one projecting member to face the inward surface of the base. The at least one projecting member restricts movement of the adapter in a direction corresponding to an axis of rotation of the adapter using the at least one projecting member.

An elongate tubular lighting assembly having a body with a length between spaced first and second ends. The tubular lighting assembly has a source of illumination and first and second connectors respectively at the first and second body ends. 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 present application discloses a lighting device, which comprises a light source (110), a connection structure (120) comprising a cap (122, 124) provided at an end thereof, and a transmission mechanism (130); the cap is electrically connected with the light source; the transmission mechanism comprises a driving component (132) movably connected to a rotation component (134) on which the cap is mounted, wherein a movement of the driving component relative to the rotation component causes the rotation component with the cap to rotate. Just by touching, pressing, sliding or rotating a button (155) set on the surface of the panel (150), the rotation component is driven to rotate, and then the two pins of the two caps are quickly inserted into the corresponding sockets.
