Description

Technical field [0001] The patent of the present invention relates to the field of lighting technology, in particular to a rotary plug-in combined LED lighting device. Background technique [0002] LED lighting is also known as solid-state lighting. As the third-generation lighting technology after incandescent lamps and fluorescent lamps, it has the characteristics of energy saving, environmental protection, safety and reliability. The solid-state light source is a promising new type of replacement for traditional lighting fixtures in the next decade. The light source represents the future of lighting technology. [0003] The desk lamp is mainly for decoration and will not affect the light of the entire room. Its function is limited to the periphery of the desk lamp, which is convenient for reading, studying, working and saving energy. The table lamp has far surpassed the value of the table lamp itself, and the table lamp has become a rare work of art. In addition, the table lam...

Problems solved by technology

Users can freely plug and unplug according to the actual use conditions, and combine them into the required structure; however, the products of this structure use DC female and male connectors for electrical connection, and are connected by plugging and unplugging. The connector is easy to loose, resulting in poor contact. In addition, the DC female and male connections can only be connected in series with one positive and one negative wire, and other connection methods cannot be realized. The lighting control is limited and the function is relatively single.
