Disclosed is a lamp holder, which includes a front housing, a rear housing detachably connected to one end of the front housing, an end cap detachably connected to the other end of the front housing and a first connecting cap provided in the rear housing for connecting with a lamp, and further includes a compression spring, a conducting sheet and a conducting pole for contacting with an external power source. When one end of the lamp holder is connected with an external lamp socket, the conducting pole can keep a good electrical connection with the external power source due to the action of the compression spring; and when the other end of the lamp holder is connected with the lamp, the resilient sheet can keep a good electrical connection with the lamp due to the resilient sheet.

Embodiments relate to a lighting device that includes or retains a plurality of solid-state light emitters and is capable of providing one or more of omni-directional lighting and task lighting. Other embodiments relate to modular lighting systems for providing the same.

An LED lamp that can take the place of incandescent lamps. An elevated light source is positioned above a screw-type base. A first plurality of LEDs is connected in a series on one side of a flat substrate and a second plurality of LEDs, equal in number to the first, is connected in series on an opposite side of the substrate. Each LED of the first and second plurality of LEDs is mounted proximate a heat sink and a drive circuit is provided for the LEDs, with the drive circuit being located proximate and electrically connected to the screw base.

An LED lighting device or LED lamp comprises one or more LED packages, and a switch comprising at least two selectable positions. At least one selectable position corresponds to a set operating mode and one selectable position corresponds to a configurable operating mode. When the switch is in the selectable position corresponding to the set operating mode, responsive to receiving an indication of user input for selecting user-selected operating light qualities, the one or more LED packages continue to be operated in accordance with the predefined operating light qualities corresponding to the set operating mode. When the switch is in the selectable position corresponding to the configurable operating mode, responsive to receiving an indication of user input for selecting user-selected operating light qualities, operation of the one or more LED packages is modified in accordance with the user-selected operating light qualities.

A light emitting device including a bulb having a side surface, a board elongated longer in a first direction than in a second direction perpendicular to the first direction, and a plurality of light emitting elements mounted on the board. Each of the plurality of light emitting elements has an upper surface and a lower surface opposite to the upper surface, where the lower surface is mounted on the board. The device includes a plurality of sets of metal plates and leads electrically connected to the plurality of light emitting elements, and a wavelength conversion member covering the light emitting elements and a portion of each of the metal plates. The board, the light emitting elements, the sets of metal plates and leads, and the wavelength conversion member are disposed in the bulb. The upper surface of each of the light emitting elements faces the side surface of the bulb.

An anti-flicker and anti-glow switchable load apparatus to be installed in the light socket of a commonly powered electronic switching device, such as a motion activated light switch. An energy efficient light bulb or lamp, such as a cathode fluorescent lamp or light emitting diode is then screwed into the apparatus. A first embodiment of the present invention includes a switchable light source, a switchable load, a controller, and a voltage sensor. When the present invention in the first embodiment detects a higher voltage, thus indicating the lamp has been switched from the “off” state to the on state, the switchable load is disconnected, and the current is re-routed to pass through the energy efficient lamp.

A bipartite capper component for an illuminating lamp includes a first portion formed of a first material and a second portion formed of a second material different from the first material. The second portion of the capper component is in contact with the first portion of the capper component. The first portion of the capper component is configured to threadedly engage within a standard threaded metal base component of the illuminating lamp.

Embodiments of the present invention are related to a lamp assembly that may have a base unit that includes a base, a power supply housing, a power supply, and a power supply cover. The base unit may be operable to detachably engage a lamp unit to form a functional lighting device. Furthermore, the base unit may be operable to be interchanged with a plurality of lamp units.

An LED lighting device or LED lamp comprises one or more LED packages, driver circuitry configured to provide a controllable electrical current to at least one of the one or more LED packages during operation of the LED lighting device or LED lamp; and a switch comprising at least two selectable options. At least one selectable option corresponds to a set operating mode and one selectable option corresponds to a configurable operating mode. During operation, when the switch is in a position to select the selectable option corresponding to the configurable operating mode, the driver circuitry operates at least one of the one or more LED packages to emit light having operating light qualities corresponding to a most recently received signal indicating a user-selection. The user-selection may be provided through user interaction with an interactive element of the LED lighting device or LED lamp, wall switch, or portable remote switch.

A waterproof socket-type halogen lamp for a livestock barn comprises a fixing body forming a hollow part, a side plate finishing the outside of the fixing body, a contact point, a wire, an annular insulator insulating the fixing body, a spring which is embedded in the hollow part and of which an outer side is supported by the side plate, an inner side supports the outer side of the annular insulator to provide restoration force while supporting one terminal of the tube halogen lamp through the contact point, and an inner waterproof packing which prevents moisture or dust from penetrating to the inner end of the fixing body and has a closed curve shape with a terminal passing groove through which a lamp terminal housing passes, and a tube halogen lamp in which lamp terminals at both ends are connected with the contact point by two socket parts.
