Description

Technical Field

[0001] The utility model relates to the technical field of LED diodes, in particular to a novel LED chip diode. Background Art

Although the cured protective glue can support and protect the components, when the internal component connections are damaged or have poor contact, the protective glue needs to be melted before repair. In addition, the use of protective glue for protection adds an extra curing operation step in the process, which reduces the efficiency of LED chip diode packaging.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-3A new type of LED chip diode includes a packaging substrate 1 and a component 2 mounted on the packaging substrate 1. A protective cover 3 is provided on the packaging substrate 1. The protective cover 3 is used to replace the traditional protective glue. On the one hand, it is convenient for the staff to perform multiple operations on the internal component 2. On the other hand, it can also reduce the packaging steps and no curing operation is required, which saves the packaging cost. Connectors are provided on both sides of the protective cover 3. The protective cover 3 is fixedly connected to the packaging substrate 1 through the connector. A light-transmitting port 8 is penetrated through the protective cover 3. The light-transmitting port 8 is used to transmit the light emitted by the component 2. A dimming component for changing the light color of the diode is provided on the packaging substrate 1.

[0022] Reference Figure 2 The connecting piece includes a connecting plate 4, a card block 5, a connecting groove 6 and a card slot 7. The connecting plate 4 is fixedly connected to the bottom of the protective cover 3, the card block 5 is fixedly connected to the side wall of the connecting plate 4, the connecting groove 6 is arranged on the packaging substrate 1, and the card slot 7 is arranged on the side wall of the connecting groove 6. The card slot 7 is adapted to the card block 5. The connecting plate 4 and the card block 5 are both made of elastic plastic. In this way, the fixing of the protective cover 3 can be achieved through the deformation of the connecting plate 4 and the card block 5, which is convenient for the staff to operate and saves the packaging cost.

[0023] Reference Figure 1 and Figure 3 The dimming component includes a plurality of light-transmitting films 9, a rotating shaft 10, a plurality of connecting rods 11 and a screw groove 12. Each light-transmitting film 9 is fixedly connected to the rotating shaft 10 through the connecting rod 11. The color of each light-transmitting film 9 is different. The rotating shaft 10 passes through the protective cover 3, and the rotating shaft 10 is rotatably connected to the protective cover 3. The screw groove 12 is opened on one end of the rotating shaft 10 located outside the protective cover 3. By using the screw groove 12, the staff can rotate the rotating shaft 10 to realize the rotation of the light-transmitting film 9, thereby changing the color of the light and improving the flexibility of the LED chip diode.

[0024] Reference Figure 1 and Figure 3 A plurality of light-transmitting films 9 are arranged at equal intervals in the circumferential direction, and the sizes of the light-transmitting films 9 and the light-transmitting opening 8 are adapted to each other. When the rotating shaft 10 is rotated so that the light-transmitting films 9 of different colors coincide with the light-transmitting opening 8, the light emitted by the device can be made different in color, thereby improving the practicality of the LED chip diode.

[0025] Reference Figure 2 The cross section of the card block 5 is a triangular structure. Under the action of the inclined surface of the card block 5, the connecting groove 6 will squeeze the card block 5, so that the card block 5 and the connecting plate 4 are deformed, and then the card block 5 can be inserted into the card slot 7 to fix the protective cover 3.

[0026] Reference Figure 1 A plurality of openings 13 are provided on the packaging substrate 1 , and the openings 13 play a role in heat dissipation, thereby extending the service life of the component 2 .

[0027] The specific working principle of the utility model is as follows:

[0028] After the component 2 is connected to the packaging substrate 1, the protective cover 3 is covered so that the connecting plate 4 and the card block 5 are inserted into the connecting groove 6 together. The inner side of the connecting groove 6 will squeeze the card block 5, so that the connecting plate 4 and the card block 5 are squeezed and deformed. When the card block 5 is directly opposite to the card slot 7, under the elastic force of the connecting plate 4 and the card block 5, the card block 5 is inserted into the inside of the card slot 7, thereby achieving the fixing effect of the protective cover 3 and ensuring the protection effect of the component 2. When there is a problem with the connectivity between the component 2 and the packaging substrate 1, the staff only needs to pinch the two sides of the protective cover 3 so that the two sides of the protective cover 3 are compressed and deformed, thereby driving the card block 5 to move into the connecting groove 6, and then pull the protective cover 3 upward to realize the removal of the protective cover 3, which is convenient for the staff to operate and improves the packaging efficiency;

[0029] When the LED chip diode is connected to the circuit, it will emit light, and the light will pass through the light-transmitting port 8. Insert a screwdriver or other suitable tool into the screw slot 12, and turn the tool to rotate the shaft 10. The rotation of the shaft 10 drives the connecting rod 11 and the light-transmitting film 9 to rotate. When light-transmitting films 9 of different colors overlap with the light-transmitting port 8, the color of the light transmitted is also different. In this way, the color of the light emitted by the LED chip diode can be adjusted. In this way, the staff can flexibly adjust the light color according to the usage scenario, thereby improving the flexibility and practicality of the LED chip diode.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
