Problems solved by technology

[0003] Although the existing refrigerator lighting lamp can realize good lighting work, there are the following disadvantages: 1. The PCB light board used in the existing refrigerator lighting lamp is a traditional printed circuit board. Corrode the non-line parts, that is, the copper layer that is not connected to the LED lamp
It can be seen that this kind of light board not only has a complicated processing technology, which affects the processing efficiency, but also causes a lot of waste of copper raw materials and increases production costs.
2. In the existing refrigerator lighting lamp, the lampshade, PCB lamp board and cover plate are independent of each other. When assembling, the PCB lamp board connected with the conductive line needs to be packaged in the area between the lamp shade and the cover board. The existing structural design is not conducive to controlling the cost of raw materials, nor is it conducive to improving assembly efficiency
Because the external force applied to the light-transmitting plate to rotate requires a certain point of force, therefore, while the upper end of the light-transmitting plate is screwed to the lampshade, its lower end is usually protruding from the lampshade, so that the refrigerator lamp can be installed on the lampshade. In the refrigerator, it will not only affect the storage volume in the refrigerator box, but also affect the aesthetic feeling of the box

Abstract

The present invention discloses an LED lamp panel printed with conductive ink, a manufacturing technique of the LED lamp panel, and an integrated LED lamp for a refrigerator. The LED lamp panel comprises an insulation carrier, a plurality of LED lamps are fixed on the insulation carrier, conductive ink circuits contacting with two electrodes of each LED lamp are arranged at the two electrodes of the LED lamp on the insulation carrier, and the insulation carrier is also provided with an electricity conducting device contacting with tail ends of the conductive ink circuits. Through arrangement of the conductive ink circuits, the insulation carrier can be made of a flexible material or of a hard material. When a flexible material is used, the appearance of the insulation carrier can be designed according to requirements of clients, thus to further raise an aesthetic feeling of refrigerator lamps. When a hard material is used, the insulation carrier can directly replace a cover plate to realize packaging of the LED lamps and the conductive ink circuits, and through the above integral structural design, production processes can be reduced, and production costs can also be lowered.
