This disclosure relates to light emitters having a communication or power connector.
Portable electronic devices such as smart phones, tablets, and laptops have become popular in recent years. For example, one person may have a portable music recording device, a portable smartphone, a portable tablet, and a portable laptop. These portable electronics are usually powered by batteries and may be used in battery mode or when the device is plugged-in a power supply (e.g., a wall outlet or another portable electronic device. In addition, most of the batteries of these devices can be recharged using an adapter cord or a plug-in charging unit having a unique plug that connects to a receptacle that is unique to a specific portable device or manufacturer.
When a person is charging the batteries of multiple portable devices the cords may get tangled and cluttered across a floor surface. In addition, the tangled and cluttered cords may cause a person to trip over the cords, potentially causing the device(s) to fall on the ground and break.

Like reference symbols in the various drawings indicate like elements.
Owning multiple portable devices, such as laptops, tablets, and smartphones, increases the number of cords and chargers a person may use to charge the portable electronic devices. This multiplicity of cords leads to an increase in cord clutter and/or cord entanglement on the ground, which may lead to a person tripping over the cords.

The power or communication receptacle 146 may be a power receptacle 146a or a communication receptacle 146b or may be both a power and communication receptacle, such as, but not limited to, a universal serial bus (USB) or a high-definition multimedia interface (HDMI). In some examples, the communication receptacle 146b is an Ethernet cable receiver.
The fixture body 110 is configured to support a light emitter 144. The light emitter 144 may be, but is not limited to, an incandescent light bulb, a fluorescent lamp or tube, a compact fluorescent lamp (CFL), or an LED lamp. An incandescent light bulb produces light with a filament wire that produces light when heated to a high temperature. An electric current passing through the wire causes the wire to be heater to the high temperature. Therefore, when a light switch connected to a light bulb is turned on, current passes through the filament wire and increases the temperature of the filament wire to high temperature creating light. A fluorescent lamp or tube is gas charged and contains mercury atoms that are excited when an electrical current passes through the lamp or tube. The excited mercury atoms produce short-wave ultraviolet light producing visible light. Fluorescent lamp or tube is more efficient in producing light than incandescent light bulbs. A compact fluorescent lamp is a fluorescent lamp or tube designed to mimic the size of an incandescent bulb and therefore replace incandescent bulbs. A light-emitting diode (LED) bulb uses light emitting diodes as the source of light. LED bulbs are initially more expensive than fluorescent and incandescent bulbs; however, the LED lights have a higher efficiency and last longer.

In some examples, the power and/or communication receptacle 146 is/are positioned between about one (1) inch and about three (3) inches away from the received light bulb 544. Additionally or alternatively, the power and/or communication receptacle 146 face oppositely away from the female light bulb socket of the lighting fixture. For instance, when the existing lighting fixture is a ceiling lighting fixture, the female light bulb socket thereof may receive the male electrical connector 530 such that the power and/or communication receptacle 146 is accessible for receipt by a power and/or communication cable associated with an electronic device. Thus, the power and/or communication receptacle 146 faces oppositely away from the male electrical connector 530. Accordingly, the existing lighting fixture may provide power to the power and/or communication receptacle 146 when the male electrical connector 530 is electrically connected to the female light bulb socket of the lighting fixture.
