Qingdao University of Technology students invented patents for reusable LED lights

Recently, the national utility model patent “A LED lamp with replaceable lamp bead” (patent number 201320713554.7) applied by science and technology innovation enthusiasts from Qingdao University of Technology, Yang Fengguang and Li Haixin, was officially authorized by the State Intellectual Property Office. Students independently innovate and design inventions.

The design of the LED replaceable lamp bead circuit board is to improve the PCB circuit board to adapt to the existing LED lamp bead type in the market, and the combination of the conductive cylinder and the elastic piece is embedded in the PCB circuit board, and the tail end of the conductive tube is The metal piece is folded and soldered to form a slot on the PCB circuit board line, and the LED lamp bead is directly inserted into the slot, and the elastic piece can fix and conduct the LED lamp bead.

At present, most countries pay more and more attention to the energy-saving and environmental protection issues of lighting. According to the huge energy-saving advantages of LED lamps, countries are vigorously promoting the use of LED lamps. The user thus damages the individual LED lamp beads to affect the overall brightness, so that most of them are discarded, and the invention can be recycled by recycling the discarded lamps, saving resources.
