Description

Technical Field

[0001] The utility model relates to the technical field of LED lamp beads, in particular to an outdoor LED lamp bead module. Background Art

[0002] LED lamp beads, the full name of which is "light-emitting diode lamp beads", are a new type of lighting source that can convert electrical energy into light energy. Compared with traditional lighting bulbs, LED lamp beads have higher brightness, lower energy consumption, longer service life and are more environmentally friendly. At the same time, LED lamp beads can also meet more diverse lighting needs by combining, adjusting and controlling colors. In addition, due to its advantages such as low power consumption, high brightness and scalability, LED lamp beads are also widely used in outdoor landscape lighting, automotive lighting, driverless cars, smart homes and other fields.

[0003] In the prior art, when LED lamp bead modules are used outdoors, they are generally combined with multiple LED lamp bead modules for use in green belt landscape lights, bridge lighting, and business signs. LED lamp bead modules work continuously for a long time at night. The temperature in southern my country is relatively high throughout the four seasons. When LED lamp bead modules are arranged outdoors, they are easily affected by the ambient temperature, and the light-emitting semiconductor of the LED is generally wrapped with phosphorus, which reduces the heat dissipation effect. When illuminated for a long time, heat accumulates inside the lamp bead module, causing the temperature to continue to rise, eventually causing thermal runaway of the LED lamp bead module. The existing heat dissipation structure often dissipates heat from the LED lamp body, and the LED lamp bead module has a thicker polymer shell that blocks the transfer of heat, making it difficult for the heat dissipation structure to dissipate the heat from the light-emitting semiconductor of the LED lamp bead. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes an outdoor LED lamp bead module.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an outdoor LED lamp bead module, including a lamp bead body, the lamp bead body is provided with a phosphor groove, an N-pole semiconductor is fixed at the bottom of the phosphor groove, a P-pole semiconductor is fixed at the top of the N-pole semiconductor, a P-pole wiring hole is provided at the bottom of the phosphor groove, and an N-pole wiring hole is provided at the bottom of the phosphor groove, contacts are fixed on both sides of the lamp bead body, glue pouring grooves are provided on both sides of the lamp bead body, a linear array of high-friction slide grooves is provided on the inner wall of the glue pouring groove, and a cooling plate is slidably connected to the inner wall of the high-friction slide groove. In the prior art, when LED lamp bead modules are used outdoors, they are generally combined and used for green belt landscape lights, bridge lighting, and business signs. LED lamp bead modules continue to work for a long time at night. The temperature in southern my country is relatively high in all seasons. When LED lamp bead modules are arranged outdoors, they are easily affected by the ambient temperature, and the light-emitting semiconductor of the LED is generally wrapped with phosphor, thereby reducing the heat dissipation effect. When lighting for a long time, heat accumulates inside the lamp bead module, making The temperature continues to rise, eventually causing thermal runaway of the LED lamp bead module, and the existing heat dissipation structure often dissipates heat for the LED lamp body. The LED lamp bead module has a thicker polymer shell that blocks the transfer of heat, making it difficult for the heat dissipation structure to dissipate heat for the light-emitting semiconductor of the LED lamp bead. To address this problem, the utility model solves it by installing a cooling plate, and realizes that when the LED lamp bead module is used outdoors with a high ambient temperature, the staff slides and connects a suitable number of cooling plates to the high-friction slide groove according to its use environment. The cooling plate conducts the heat inside the lamp bead body through its own good heat transfer effect, thereby reducing the internal temperature of the lamp bead, keeping it at a suitable working temperature, and preventing overheating and runaway caused by long-term use. When the lamp bead is used in high-altitude and cold areas, the staff may not install the cooling plate, so that the temperature generated when the lamp bead emits light can make up for the working temperature. After the cooling plate is installed, the staff fills the glue filling groove with waterproof glue to improve the waterproof effect of the lamp bead when it is used outdoors, thereby improving the applicable environment of the equipment and increasing the safety of the equipment.

[0006] Preferably, a conical sink is provided at the bottom of the phosphorus tank, an N-pole semiconductor is fixed at the bottom of the conical sink, an N-pole wiring groove is provided at the bottom of the conical sink, and the inner wall of the N-pole wiring groove intersects with the inner wall of the N-pole wiring hole. In the prior art, the light emission of the LED lamp bead requires that both the N-pole semiconductor and the P-pole semiconductor be installed with wires, and current is allowed to flow between the semiconductors, thereby making the semiconductor emit light, while in LED lamp beads that can emit light of multiple colors, there are more than one N-pole semiconductor and P-pole semiconductor, and multiple semiconductors require multiple wires to be connected. The existing multiple wires are relatively messy after installation and have no better fixing structure. Once the wires are damaged, the wires in contact with them will short-circuit, causing the lamp bead to burn, reducing the stability of the equipment. In response to such problems, the utility model adopts the method of opening an N-pole wiring groove to solve the problem, so that the wires of multiple N-pole semiconductors are routed and arranged through the N-pole wiring groove, avoiding their messy arrangement or contact with the wires of the P-pole semiconductor. Even if the wires are broken, they will not cause a short circuit, and they are neatly arranged, which is convenient for staff to repair, thereby achieving the effect of improving the safety of equipment use.

[0007] Preferably, a weight-reducing groove is provided at the bottom of the lamp bead body, and contacts are fixed on both sides of the inner wall of the weight-reducing groove. In the prior art, the contacts of most LED lamp bead modules are fixed on both sides of the equipment. This arrangement is convenient for soldering and fixing, but when a large number of LED lamp bead modules are used in combination, the contacts are closely connected, and soldering easily touches each other for conductivity, connecting the contacts, causing damage to the LED lamp bead module, and reducing the yield rate. To solve such problems, the utility model solves them by providing a weight-reducing groove, thereby achieving the goal of installing the contacts in the weight-reducing groove, spraying solder paste in the weight-reducing groove, and then installing the equipment on the lamp body. The lamp bead body shields the contacts and solder paste to avoid power supply with other lamp bead bodies, thereby achieving the effect of improving the product yield rate.

[0008] Preferably, tin-filling holes are provided on both sides of the lamp bead body. When fixing the lamp bead, the user can also place the lamp bead body on the lamp body, and then fill solder paste into the weight-reducing groove through the tin-filling holes to complete the fixation.

[0012] Beneficial Effects

[0013] 1. In the prior art, when LED lamp bead modules are used outdoors, they are generally combined with multiple LED lamp bead modules for use in green belt landscape lights, bridge lighting, and business signs. LED lamp bead modules work continuously for a long time at night. The temperature in southern my country is relatively high in all seasons. When LED lamp bead modules are arranged outdoors, they are easily affected by the ambient temperature. In addition, the light-emitting semiconductor of LED is generally wrapped with phosphorus, which reduces the heat dissipation effect. When illuminated for a long time, the heat inside the lamp bead module accumulates, causing the temperature to continue to rise, eventually causing the LED lamp bead module to thermally run away. In addition, the existing heat dissipation structure often dissipates the heat of the LED lamp body. The LED lamp bead module has a thick polymer shell that blocks the transfer of heat, making it difficult for the heat dissipation structure to dissipate the light-emitting semiconductor of the LED lamp bead well. Heat dissipation, in order to solve this type of problem, the utility model adopts the method of installing cooling plates to achieve a solution. When the LED lamp bead module is used outdoors where the ambient temperature is relatively high, the staff can slide and connect an appropriate number of cooling plates to the high-friction slide groove according to its use environment. The cooling plates can export the heat inside the lamp bead body through their own good heat transfer effect, thereby reducing the internal temperature of the lamp bead, so that it can maintain a suitable working temperature and prevent overheating and runaway caused by long-term use. When the lamp bead is used in high-altitude and cold areas, the staff can not install the cooling plates, so that the temperature generated when the lamp bead emits light can make up for the working temperature. After the cooling plates are installed, the staff can fill the glue filling groove with waterproof glue to improve the waterproof effect of the lamp bead when it is used outdoors, thereby improving the applicable environment of the equipment and increasing the safety of equipment use.

[0014] 2. In the prior art, the light emission of LED lamp beads requires that wires be installed on both the N-pole semiconductor and the P-pole semiconductor, and that current flow between the semiconductors to make the semiconductors emit light. In LED lamp beads that can emit light of multiple colors, there is more than one N-pole semiconductor and P-pole semiconductor, and multiple semiconductors require multiple wires to connect. The existing multiple wires are relatively messy after installation and do not have a good fixed structure. Once a wire is damaged, the wires in contact with it will short-circuit, causing the lamp bead to burn, reducing the stability of equipment use. To address this problem, the utility model solves it by opening an N-pole wiring trough, and realizes the wiring of multiple N-pole semiconductors. The wires are arranged through the N-pole wiring trough to avoid their messy arrangement or contact with the wires of the P-pole semiconductor. Even if a wire is broken, it will not cause a short circuit. The wires are arranged neatly, which is convenient for staff to repair, thereby achieving the effect of improving the safety of equipment use.

[0015] 3. In the prior art, the contacts of most LED lamp bead modules are fixed on both sides of the equipment. This arrangement is convenient for soldering and fixing. However, when a large number of LED lamp bead modules are used in combination, the contacts are closely connected, and soldering easily touches each other for conductivity, connecting the contacts, causing damage to the LED lamp bead modules and reducing the yield rate. To solve this problem, the utility model adopts a method of opening a weight-reducing groove to achieve the solution. The contacts are installed in the weight-reducing groove, solder paste is sprayed in the weight-reducing groove, and the equipment is installed on the lamp body. The lamp bead body shields the contacts and solder paste to avoid being energized with other lamp bead bodies, thereby achieving the effect of improving the product yield rate.
