Description
Technical Field
The utility model relates to a LED lamp area field, concretely relates to outsourcing PVC resin's LED lamp area.
Background
In the LED lamp strip externally coated with PVC resin in the prior art, the PVC resin is used for fixing the circuit board in a way that PVC clamps the two sides of the circuit board of the lamp strip without components to form fixation, the circuit board is required to be designed and manufactured into plate edges without welding the components on the two sides in the way, so that the cost of the circuit is high, and the externally coated PVC resin is also required to be designed and manufactured into a clamping structure for clamping the circuit board inside, so that the using amount of the externally coated PVC resin is increased, and the cost of PVC is increased.
In order to overcome above defect and not enough, the utility model discloses the naked lamp area of circuit board that will weld the component, the PVC membrane of glue is taken at the back subsides one deck, reuse extruder outsourcing PVC resin, the extruder is melting outsourcing PVC resin heating, extrude again on the naked lamp area of circuit board, the PVC resin of hot melt state can form the bonding of fusion formula with the PVC membrane at the circuit board back, because all be PVC resin material, just formed the hot melt bonding naturally at the interface, the lamp area is fixed to this kind of mode, the circuit board in lamp area need not the flange edge that the component was welded in the design preparation, can be narrower with the circuit board preparation, and is with low costs, outsourcing PVC also need not design into the blank pressing structure that both sides pressed the circuit board edge simultaneously, make outsourcing PVC resin quantity greatly reduced, the messenger cost is lower.
SUMMERY OF THE UTILITY MODEL
The utility model relates to an outsourcing PVC resin's LED lamp area, particularly, paste the component with the circuit board after, paste the glued PVC membrane in the one deck area at the circuit board back, make the naked lamp area of back area PVC membrane, then with the extruder with PVC melting back, extrude the parcel to the naked lamp area on, when the PVC of the PVC surface contact heat of the naked lamp area back melts when extruding, PVC membrane surface can be heated, and form the heat with the PVC sizing material that has melted and melt the bonding altogether, make naked lamp area and outsourcing PVC glue and bond one wholly.
According to the utility model provides an outsourcing PVC resin's LED lamp area, include: the back of the circuit board is provided with a PVC film with glue; a circuit board; a component comprising an LED; wrapping PVC resin; the LED lamp strip is characterized in that the circuit board is a flexible circuit board, the back surface of the circuit board is formed by bonding a bare metal circuit and a PVC film with glue together, or the back surface of the circuit board is provided with a layer of insulating resin, the insulating resin and the PVC film with glue are bonded together, the PVC film and the PVC resin are fused and bonded together, so that the lamp strip and the PVC resin are bonded into a whole, the circuit board is a circuit board with a single-layer circuit, or a circuit board with a double-layer circuit, or a circuit board with a three-layer circuit, and an LED-containing element is welded on the front surface of the circuit.
The details of one or more embodiments of the invention are set forth in the accompanying drawings and the description below.
