Description

Technical Field

[0001] This utility model relates to the field of light-emitting diode technology, specifically a bendable light-emitting diode based on a flexible substrate. Background Technology

[0002] A light-emitting diode (LED) is a solid-state light-emitting device based on the semiconductor PN junction effect. Its core principle is that when a forward voltage is applied to the PN junction, electrons and holes recombine in the junction region, releasing energy and radiating light in the form of photons. The color of the emitted light can be changed by altering the metal impurities inside the PN semiconductor.

[0003] Currently, when flexible light-emitting diodes based on flexible substrates are used, the island bridges used to connect the circuits are subjected to deformation stress when the diodes are bent, which can easily cause damage at the island bridge connections and reduce their service life. Utility Model Content

[0004] The purpose of this invention is to provide a bendable light-emitting diode based on a flexible substrate, in order to solve the problem mentioned in the background art that when the diode is bent, the island bridge used to connect the circuit is subjected to deformation stress, which easily leads to damage at the island bridge connection and reduces the service life. To achieve the above objectives, this utility model provides the following technical solution: a bendable light-emitting diode based on a flexible substrate, comprising a flexible substrate, a protective component disposed on the top of the flexible substrate, the protective component comprising an integrated positive electrode connector, an island bridge, a reset block, a connecting block, an N-shaped semiconductor, a P-type semiconductor, and a fluorescent tube, the integrated positive electrode connector being fixedly connected to the top of the flexible substrate, and a plurality of island bridges being fixedly connected to one side of the integrated positive electrode connector, the island bridges being V-shaped and having a honeycomb-like internal structure, the protective component disposed on the top of the flexible substrate, the protective component further comprising a reset block, the reset block being fixedly connected to the inner wall of one side of the flexible substrate, and the reset block being movably connected to the island bridges, the connecting block being fixedly connected to one side of the reset block, and an N-shaped semiconductor being fixedly connected to one side of the island bridges, the N-shaped semiconductor being fixedly connected to the flexible substrate, and so on. The top of the N-shaped semiconductor is fixedly connected to a P-type semiconductor, and the top of the P-type semiconductor is fixedly connected to a fluorescent tube. Several connecting tubes are fixedly connected to one side of the P-type semiconductor, and an integrated negative electrode connecting piece is fixedly connected to the other end of the connecting tubes. This flexible light-emitting diode based on a flexible substrate, by adding protective components, integrates multiple modular small semiconductors within both the N-shaped and P-type semiconductors. The island bridge is a V-shaped circuit with connections on both sides. When bending occurs, the rigid parts such as semiconductors move but do not deform. The island bridge adapts to the connection through deformation. The island bridge adopts a honeycomb-like structure inside, which can effectively absorb the stress generated by deformation and reduce the impact of stress on the connection on both sides. The reset block adopts an elastic memory material, which can slowly reset and fully surround and support the island bridge to reduce the deformation of the island bridge and further absorb stress, thereby protecting the circuit connection and improving the service life.

[0005] Further preferably, the flexible substrate is internally provided with an adjustment component, which also includes an island bridge two. Several island bridge twos are fixedly connected to the top of the flexible substrate, and the island bridge twos are electrically contacted with island bridge one. A reset block two is fixedly connected to the inner wall of one side of the flexible substrate. A pass plate is fixedly connected to the bottom of the island bridge two, and the island bridge two is electrically contacted with the pass plate. This flexible substrate-based bendable light-emitting diode, by adding the adjustment component, works as described above with island bridge two, reset block two, island bridge three, and reset block three. The integrated positive electrode connecting piece connects to the positive electrode of the circuit. The closed circuit is completed through island bridge one, N-type semiconductor, P-type semiconductor, connecting tube, and integrated negative electrode connecting piece. The diode emits light and becomes everyday light after color adjustment by the fluorescent tube. Island bridge two is then connected to island bridge one to introduce current. The current passes through island bridge two, pass plate, island bridge three, adjustment resistor, and integrated negative electrode connecting piece to form a circuit in parallel with the main circuit. The light emission level of the diode is adjusted by changing the resistance value of the adjustment resistor, thus improving the adjustability.

[0006] More preferably, a plurality of island bridges are fixedly connected to the top of the passage plate, and a plurality of reset blocks are fixedly connected to the inside of the flexible substrate.

[0007] More preferably, an adjusting resistor is fixedly connected to one side of the island bridge three, and the adjusting resistor is in electrical contact with the integrated negative electrode connecting piece.

[0008] In a further preferred embodiment, the flexible substrate is provided with a repair component, which includes an insulating sheet fixedly connected to the bottom of the flexible substrate. Two fixing blocks are fixedly connected to the top of the insulating sheet, and the fixing blocks are movably connected to the circuit board. This flexible light-emitting diode based on the flexible substrate, by adding the repair component, has a storage groove inside the circuit board containing liquid metal, which can flow out to repair the circuit board after the circuit board rigidly breaks, thereby repairing the circuit and improving its service life.
