A lamp socket assembly to be installed in a light socket and receive electrical power therefrom. The lamp socket assembly to provide electrical power to a surveillance device that detects an occurrence of a security event and notifies the lamp socket assembly of the occurrence. In response to the notification, the lamp socket assembly to turn on a light bulb.

A light bulb socket adapter comprising a main body having an internal cavity, the main body having a first end and a second end, the first end having an Edison screw extending therefrom, a power supply driver arranged within the main body in communication with the Edison screw, a primary light source arranged within the main body proximate the second end, the primary light source in communication with the Edison screw, a processor arranged within the main body and in communication with the power supply drive, the processor in communication with at least one sensor within the main body, the processor having a radio transceiver and at least one antenna, and an electrical output in communication with the power supply driver. The light bulb socket adapter may also include at least one of a passive heat management system and an active heat management system.

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.

An assembly includes a contact interface device, a lamp base and a circuit board. This device is connected to the circuit board and is used to bias the circuit board within the center of a cavity of a light bulb. This device contains two or more biasing portions that are connected to one another through a bridge portion. The biasing portions engage an interior threaded portion of the lamp base in order to lock into place and not allow the circuit board to move. The bridge portion allows the biasing portions to counteract one another and suspend the circuit board in the middle of the cavity of the light bulb.

A terminal member assembly 1 has ground terminals (10A, 10B) each including a main body (20) in the form of a flat plate. A coupling (30) extends from the main body (20) and a wire connecting portion (40) is connected to an extending end of the coupling (30). The ground terminals (10A, 10B) are assembled with each other with the main bodies (20) overlapping each other. At least one (10A) of the ground terminals includes an overlap area (30A) to be overlapped with the coupling (30) of the other ground terminal (10B). The overlap area is located on a surface of the coupling (30) facing the adjacent other ground terminal (10B). A contact portion (36) is located in the overlap area (30A) and projects toward the coupling (30) of the other ground terminal (10B) and is configured to contact the coupling (30) of the other ground terminal (10B).

The light bulb device with functional features may include one or more features such as a dimmer function for the light source, an on/off function for the light source, a charger function for external devices using an USB port, an electrical outlet, a night light, etc. The light bulb thus converts the AC voltage in the conventional light socket to one or more usable voltages for electronic features therein or other electronic devices. One such feature is a dimmer function, another feature is one or more USB ports for charging or operating other devices such as video camera. Also, a Bluetooth connection may allow the device to act as a speaker or projector or a clock. A video monitoring feature may be included within the device that can be monitored via Bluetooth connection to a smart phone.

The present disclosure relates to a light source (1) comprising a housing (3), a light source connector (5) at a first end (7) of the housing (3), for connecting the light source to a light fitting, and a light emitting diode, LED, circuit (9), configured to emit light through a second end (11) of the housing (3). The housing may be substantially symmetric about a symmetry axis (13) extending from the first to the second end of the housing (7), (11). The housing (3) has, at the first end (7), a first end portion (15), comprising a thread (19), made in an insulating material, and being configured to be connected to a light fitting. A light fitting comprising such a light source is also considered.

A light bulb holder structure and a light bulb having same, in which the bulb cap of the light bulb holder is provided with a plurality of grooves in a tactful manner, and the depth of the grooves is greater than that of the external threads of the bulb cap, such that after the bulb cap is mounted on the light bulb and the light bulb is mounted on the light socket, the water accumulated between the light bulb holder structure and the light socket can be effectively discharged through the grooves. As a result, failure of the insulator (connector) on the light bulb holder structure caused by water accumulation can be avoided to a certain extent, thereby improving the reliability and safety of the light bulb.
