Electric lighting system with removably couplable power device

#The present disclosure relates to electric lighting systems that have lighting elements such as LEDs and removably couplable power devices.

#Current electrical lights require plugging-in, insertion of a battery, connecting wires, or unscrewing components. Connecting wires to a battery or unscrewing components to insert a battery is a time-consuming and unpleasant experience for a user. Lights that need plugging-in also lack the aesthetic and freedom of movement and requires unsightly wiring. These problems are exacerbated when there are numerous lights to maintain. For example, a hotel or a restaurant may require one or more lights for numerous rooms or dining tables. Also, plug-in options would require electrical connections for each table. If a restaurant includes a cordless light at every table, it may take employees significant time to individually plug in each light for charging. If a restaurant includes a light with a cord, the cord may diminish the aesthetic of a cord-free table. Additionally, users that may want to change the appearance of a light may need to purchase an entirely new light, including its power device, instead of just the light itself. Finally, users may want to charge a power device for a light while the light is in use without plugging in the light during use.

#Disclosed herein are electric lighting systems that overcome the limitations of earlier systems. In some embodiments, electric lighting systems allow for easy recharging and replacement, saving time for users. These electric lighting systems may save additional time for a user such as an employee of a hotel or restaurant that set a charged light in every room or at every table each night. Some example electric lighting system embodiments allow for quick and easy insertion and removal of a power device into a lighting element. Some example electric lighting systems have removably couplable power devices such that the power device can be charged while another power device is in use with a lighting element. Such functionality allows a user to, for example, provide a light for a guest at a table in a restaurant, while charging another power device. The removably couplable functionality overcomes disadvantages of other systems which would require a user to purchase two lights for continuous use, since the power device cannot be removed to be charged.

#Users of lighting device may desire to use a lighting device without plugging the lighting device into a wall. For example, a restaurant may desire to place a lighting device on patrons' tables, without laying wires across the floor or the table. Additionally, lighting devices may benefit from the aesthetic of having no wire and practical benefit of not impeding limited space, such as at a restaurant table. Use of such mobile lighting devices may present challenges for powering the lighting devices.

#Without receiving power directly from an electrical outlet of a wall, lighting devices may therefore include mobile power devices that retain charge to power the light without the need for plugging in to the wall while the lighting device is turned on. The lighting device will be able to turn on if it receives sufficient power from the power device. Eventually, the power device will transfer enough energy to the lighting device that it becomes depleted and cannot provide enough power to the lighting device. A user may ultimately need to charge a power device such that it may once again power the lighting device. But recharging the power device will require another source of electric power, such as an electrical outlet.

#Recharging a power device takes time and effort and can reduce portability. A user may interchange a power device connected to the lighting device, move the lighting device or power device to a location where it may be charged, or otherwise direct power (for example, by extension cord) to the location of the lighting device. The recharging effort is increased when there are numerous lighting devices to be used. An employee of a hotel, for example, may need to recharge hundreds of power devices so that the power devices and lighting devices can be used again for each hotel room. Additionally, a user may want to keep a lighting device in continuous use, such that the lighting device may remain at its intended point of use, such as a restaurant table, lobby space, meeting room, or hotel room.
