Problems solved by technology
Because an insulating interval is required between the positive and negative electrodes, and in order to improve the reflective performance of the lead frame, electroplating is usually performed to form a bright coating. Even if an insulating material is used to fill it, the sealing effect between the insulating material and the coating is not good. , Oxygen, impurities, etc. infiltrate along the junction between the insulating material and the metal material, and often this place becomes the source of leakage. After a long time of use, it will affect the light-emitting chip, gold wire and other components, resulting in reliable LED devices. decreased sex
On the other hand, heat dissipation has always been a major problem faced by light-emitting diode devices

The invention provides a high-reliability light emitting diode support which comprises a lead frame and a base arranged on the lead frame, wherein a reflecting cavity is defined by the lead frame and the base, the lead frame comprises a positive electrode frame and a negative electrode frame, a gap is formed between the positive electrode frame and the negative electrode frame, grooves communicated with the gap are recessed at the edges, near the gap, of the positive electrode frame and the negative electrode frame, an insulating component is arranged in the gap and the grooves, the bottom surface of each groove is provided with a rough part which extends in the length direction of the groove and is subjected to chemical corrosion treatment previously, pattern structures are arranged in at least partial regions of the bottom surfaces of the positive electrode frame and the negative electrode frame, and the base and the insulating component are made of a thermosetting resin. In the support, the grooves are provided and roughened so that the reliability of the support is improved, and due to the formation of the pattern structures, the heat dissipation efficiency of the support is improved and a three-dimensional heat dissipation way is established.
Description
technical field [0001] The invention relates to a light-emitting device, in particular to a high-reliability light-emitting diode bracket. Background technique [0002] Due to the characteristics of high luminous efficiency, small size, and no pollution, light-emitting diode devices are being widely used in TV backlights, graphic display screens, decorative lighting and other fields. With the price reduction of raw materials such as chips, packaging glue and brackets, and the continuous improvement of chip luminous efficiency, light-emitting diodes have begun to enter the field of indoor lighting such as commercial lighting and home lighting. [0003] Light-emitting diode devices usually include a bracket and a light-emitting chip. The bracket includes a base and a lead frame. , the lead frame includes positive and negative electrodes. A big problem that light-emitting diode devices with this structure usually face is the issue of hermeticity. Because an insulating interv...
