The present invention relates to a lighting device.
The invention of light bulbs allows people to move at night without restriction. There are various types of light bulbs such as conventional T8 fluorescent lamps, T5 lamps, LEDs, energy saving bulbs, etc., and several types of lamps are developed to meet various requirements; ceiling lamps, semi-ceiling lamps, pendant lamps, downlights, wall lamps, for instance.
Strip lamps are the most common in daily life. However, sockets for connection of most of the conventional strip lamp are directly fixed to the ceiling, and the sockets are directly connected to wires arranged on the building. This kind of socket has a large size and needs to be connected to the wires, which causes a lot of inconvenience and lack of safety in installation.
The present invention is, therefore, arisen to obviate or at least mitigate the above-mentioned disadvantages.
The main object of the present invention is to provide a lighting device which has a small size, is easy to install, and provides two options of electric connection to a power source.
To achieve the above and other objects, a lighting device is provided, including: an elongate light assembly, including a power connector, the power connector being configured for electrical connection of a power wire; a base, connected to the elongate light assembly; and a head portion, detachably connected to the base, including a threaded connector, the threaded connector being electrically connected with the elongate light assembly; wherein at least one of the power connector and the threaded connector is configured to be electrically connected with a power source.
