Description

Technical Field

[0001] This utility model relates to the field of light-emitting diode technology, and in particular to a light-emitting diode with a low refractive index layer that reduces light transmission. Background Technology

[0002] Light-emitting diodes (LEDs) are commonly used light-emitting devices that release light through the recombination of electrons and holes. They are widely used in the lighting industry. LEDs offer numerous advantages, including high brightness, low power consumption, small size, long lifespan, energy efficiency, environmental friendliness, safety, reliability, and the ability to operate in various harsh environments. They are applied in various fields such as indoor and outdoor lighting, and light box decoration.

[0003] For example, a Chinese utility model patent with publication number CN215815922U includes a base, a transparent cover, a light-emitting diode (LED), a heat dissipation mechanism, and thermally conductive silicone. The transparent cover is located on the top of the base, the LED is located in the middle of the base, the heat dissipation mechanism is located on the top of the base, and thermally conductive silicone is located on the top of the heat dissipation mechanism. The heat dissipation mechanism contacts the LED through thermally conductive silicone. This patent, by setting up a heat dissipation mechanism, allows the heat sink to dissipate heat from the LED chip during use without affecting its light emission. Heat dissipation does not affect use. By setting up pins, when water flows upward along the pins, the "S"-shaped position in the middle of the pins increases the difficulty of water seepage. At the same time, the baffle blocks the water, preventing water from seeping into the interior of the transparent cover along the pins, thereby increasing the lifespan of the LED.

[0004] However, in some special cases, such as damage to the pins due to external pulling, or in the process of electronic experiments or new product development, the pin spacing, shape, etc. of different circuit boards may be different, and the original LED pins cannot be directly adapted. In order to correctly install the LED on the new circuit board and achieve the expected circuit function, the LED pins need to be replaced. In view of this, we propose an LED with a low refractive index layer that reduces light guiding. Utility Model Content

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a light-emitting diode with a low refractive index layer that reduces light transmission, including a base 1, a transparent cover 2 fixedly connected to the upper surface of the base 1, a heat dissipation component 19 provided on the upper surface of the base 1, a connection pin 3 provided inside the base 1, a plug-in groove 4 opened on the lower surface of the base 1, the connection pin 3 extending into the interior of the plug-in groove 4, a connection cylinder 5 fixedly connected to the inner wall of the plug-in groove 4, a spring 6 fixedly connected to the top wall of the connection cylinder 5, a pressure plate 7 fixedly connected to the lower end of the spring 6, the pressure plate 7 slidably connected inside the connection cylinder 5, a fixing ring 8 fixedly connected to the inner wall of the connection cylinder 5, a rectangular groove 9 opened on the upper surface of the fixing ring 8, a replaceable pin 10 provided inside the plug-in groove 4, and a connection component provided on the replaceable pin 10. With the cooperation of the connection component and the replaceable pin 10, the replaceable pin 10 can be quickly replaced during electronic testing to adapt to different specifications of sockets on the circuit board. At the same time, the replaceable pin 10 can also be quickly replaced after it is damaged.

[0024] Furthermore, the connecting assembly includes a rectangular block 11, which is fixedly connected to the upper surface of the replaceable pin 10. A rectangular triangular block 12 is fixedly connected to the upper surface of the rectangular block 11. A rectangular groove 9 is adapted to the rectangular triangular block 12 and the rectangular block 11. A conical positioning cylinder 13 is fixedly connected to the inner wall of the connecting cylinder 5, and the conical positioning cylinder 13 is adapted to the replaceable pin 10. A sealing groove 14 is provided on the inner wall of the insertion groove 4. A sealing ring 15 is fitted on the outer surface of the connecting cylinder 5, and the sealing ring 15 is adapted to the sealing groove 14. The inner wall of the plug-in slot 4 is provided with a mounting groove 16, and a rubber ring 17 is fixedly connected to the inner wall of the mounting groove 16. The outer surface of the replaceable pin 10 is provided with an annular groove 18, which is adapted to the rubber ring 17. The heat dissipation fins in the heat dissipation assembly 19 are inclined. With the cooperation of the sealing ring 15 and the rubber ring 17, the overall waterproofness of the light-emitting diode can be increased. Moreover, the heat dissipation fins, which gradually shorten on both sides and are inclined, can avoid the problem that the air cannot make good contact with most of the heat dissipation fins when flowing laterally.

[0025] The transparent cover 2 described in the text has a low refractive index layer inside to reduce light transmission, and the heat dissipation component 19 is an existing structure. For details, please refer to patent publication number CN215815922U. At the same time, the heat dissipation fins in the heat dissipation component 19 are shorter as they are closer to the sides, forming an arc shape overall.

[0026] Working principle: When replacing the replaceable pin 10, first rotate the replaceable pin 10 while pulling it downwards. When the rectangular block 11 and rectangular triangular block 12 on the replaceable pin 10 are aligned with the rectangular slot 9, the replaceable pin 10 can be pulled out. During installation, insert the replaceable pin 10 into the insertion slot 4. When the replaceable pin 10 moves, the position of the replaceable pin 10 is corrected by the conical positioning cylinder 13. Then, the replaceable pin 10 contacts the lower surface of the fixing ring 8. At this time, rotate the replaceable pin 10 and continue to push it upwards. When the rectangular block 11 and rectangular triangular block 12 are aligned with the rectangular slot 9, it can pass through the fixing ring 8. After passing through, the rectangular triangular block 12 will push the pressure plate 7 to move. When the pressure plate 7 moves, it compresses the spring 6. After the rectangular block 11 and rectangular triangular block 12 pass through the fixing ring 8, they rotate 90 degrees. At this time, release your hands and use the elastic force of the spring 6 in conjunction with the pressure plate 7 to press the rectangular block 11 and rectangular triangular block 12 to complete the fixation.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
