A light bulb apparatus includes a bulb shell, an antenna, a driver, a light source plate and a bulb cap. The light source plate has a first layer and a second layer. The LED module is disposed on the first layer. The second layer includes a metal portion. The metal portion carries heat generated by the LED module for heat dissipation. The antenna is disposed upon the first layer. A bulb cap is connected to an external power. The driver is electrically connected to the antenna for receiving a wireless signal. The driver converts the external power to a driving current supplied to the LED module.

An LED bulb has an envelope, an electrical connector, a filament, and at least one electric wire. The envelope is hollow, sealed, and translucent and has a containing portion being enclosed, a neck portion disposed at the containing portion, and an envelope axis passing through the containing portion and the neck portion. The electrical connector is connected to the neck portion. The filament is inside the containing portion, is partially attached to an inner surface of the envelope, and has a light-emitting strip having multiple LEDs and an adhering layer disposed at the light-emitting strip and partially attached to the inner surface of the envelope. The at least one electric wire is electrically connected to the filament and the electrical connector.

A light cap electrical connection structure includes a driving board, a light cap body and a first electrode pin. The light cap body is a shell structure. One end of the first electrode pin is fixed on the light cap body and further including a socket. The socket is set on the driving board and includes a connection base and a first electrode. The first electrode is set on the connecting base and has a fixed end and a connecting end. The connecting end of the first electrode is an elastic structure. The other end of the first electrode pin is inserted into the light cap body and becomes an electrical connection in elastic contact with the connecting end of the first electrode. The light cap electrical connection structure has advantages of a simple structure and being easy to automate.

A communications device for forming a network node between two or more devices or systems. The communications device has a power supply connector for connecting to a power supply in a light socket of a lighting system thereby to power the communications device. The communications device depends from the light socket by the power supply connector. The communications device also includes a receiver for receiving incoming information from one or more first devices or systems, and a transmitter for transmitting outgoing information to one or more second devices or systems.

A lighting device may include a light source, a plurality of drive circuits, and a control circuit. The light source may include a plurality of emitter circuits that are configured to emit light. The light source may include a first emitter circuit that is configured to emit light at a first color (e.g., color temperature), a second emitter circuit is configured to emit light at a second color (e.g., color temperature), and a third emitter circuit is configured to emit light at a third color (e.g., color temperature). The first, second, and third colors (e.g., color temperatures) may be on a color curve, such as a color temperature curve like the black body locus. The control circuit may be configured to control the amount of power delivered to no more than two emitter circuits to emit light when controlling the light emitted by the light source to the target intensity.
