Technical Field

[0001] The utility model relates to the technical field of LED lamps, in particular to an LED lamp with high light concentration. Background Art

[0002] Nowadays, more and more shopping malls, stadiums, stage settings and other venues use displays made of LED full-color lamp beads. The pictures are high-definition and the colors are rich and colorful. At present, the LED lamp beads used outdoors mainly include through-hole LED full-color lamp beads and surface-mount LED full-color lamp beads. And because the surface-mount LED full-color lamp beads are more efficient in the process of display production, they have been widely promoted. At present, most outdoor displays use surface-mount LED lamp beads.

[0003] The above and existing technologies have the following defects: In real life, when it is necessary to view from a long distance or the display is hung at a high altitude, due to the limitations of the structure of the surface-mount LED lamp beads, the light emitted by the LED lamp beads will have insufficient brightness due to too large a divergence angle.

[0004] Therefore, an LED lamp with high light concentration is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to solve the defect that the light emitted by the LED lamp beads has insufficient brightness due to too large a divergence angle, and to propose an LED lamp with high light concentration.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme: An LED lamp with high light concentration, including a substrate, a lamp holder is fixedly connected to the upper surface of the substrate, three LED lamp beads are fixedly connected inside the lamp holder, pins are fixedly connected to the lower surface of the substrate, and a convex lens is fixedly connected to the inner wall of the lamp slot. The side of the convex lens close to the LED lamp beads is a planar structure.

[0007] The effect achieved by the above components is that by setting the convex lens, when the LED lamp beads work, the convex lens can converge the light emitted by the LED lamp beads, thereby improving the light intensity of the LED lamp beads, and further enabling the display located at a long distance or installed at a high altitude to be clearly viewed.

[0008] Preferably, a protective cover is adhesively bonded to the surface of the lamp holder, and the convex lens is located inside the protective cover.

[0009] The effect achieved by the above components is that the protective cover adhesively bonded to the surface of the lamp holder can shield and protect the convex lens, preventing the convex lens from being scratched during the welding process.

[0010] Preferably, a heat sink is snap-fitted to the surface of the substrate, and the heat sink is an aluminum alloy sheet.

[0011] The effects achieved by the above components are as follows: The heat generated by the LED lamp beads is transferred to the substrate through the lamp holder, and the substrate transfers the heat to the heat sink. The heat sink can improve the heat dissipation effect of the substrate, thereby cooling the LED lamp beads and ensuring that the LED lamp beads can work continuously and normally.

[0012] Preferably, a plurality of fins are welded on the surface of the heat sink, and the fins are aluminum alloy sheets.

[0013] The effects achieved by the above components are as follows: The fins can increase the contact area between the heat sink and the air, thereby improving the heat dissipation effect of the heat sink.

[0014] Preferably, a plurality of heat conducting rods are fixedly connected in the substrate, the heat conducting rods are fixedly connected to the heat sink, and the heat conducting rods are copper alloy rods.

[0015] The effects achieved by the above components are as follows: The heat conducting rods can transfer the heat in the substrate to the heat sink faster, thereby cooling the substrate evenly.

[0016] Preferably, a clamping strip is fixedly connected to the surface of the heat sink, and the clamping strip is fixedly connected to the substrate.

[0017] The effects achieved by the above components are as follows: The clamping strip can improve the connection strength between the heat sink and the substrate, ensuring that the heat sink can work normally.

[0018] Preferably, a current limiting frame is fixedly connected to the surface of the substrate, the pins are located within the current limiting frame, and an inner partition is fixedly connected to the inner wall of the current limiting frame, and the inner partition is fixedly connected to the substrate.

[0019] The effects achieved by the above components are as follows: The cooperation of the current limiting frame and the inner partition can prevent the molten solder from overflowing, avoiding the occurrence of a short circuit caused by the solder contacting other circuits on the circuit board.

[0020] Compared with the prior art, the advantages and positive effects of the present utility model are that

[0021] In the present utility model, by providing a convex lens, when the LED lamp beads work, the convex lens can converge the light emitted by the LED lamp beads, thereby improving the brightness intensity of the LED lamp beads, and further enabling the display screen located at a long distance or installed at a high altitude to be clearly viewed.

[0027] In order to more clearly understand the above objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0028] In the following description, many specific details are set forth to facilitate a thorough understanding of the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0029] As Figures 1-4 shown, the present utility model provides a high-condensing LED lamp, including a substrate 1. A lamp holder 2 is fixedly connected to the upper surface of the substrate 1. Three LED lamp beads 3 are fixedly connected inside the lamp holder 2. Pins 4 are fixedly connected to the lower surface of the substrate 1. A convex lens 5 is fixedly connected to the inner wall of the lamp slot. One side of the convex lens 5 close to the LED lamp beads 3 is a planar structure. By providing the convex lens 5, when the LED lamp beads 3 work, the convex lens 5 can converge the light emitted by the LED lamp beads 3, thereby improving the light intensity of the LED lamp beads 3, and further enabling a clear view of the display screen located at a long distance or installed at a high altitude. A protective cover 6 is adhesively bonded to the surface of the lamp holder 2. The convex lens 5 is located inside the protective cover 6. The protective cover 6 adhesively bonded to the surface of the lamp holder 2 with non-drying glue can shield and protect the convex lens 5, preventing the convex lens 5 from being scratched during the welding process. A heat sink 7 is snap-fitted to the surface of the substrate 1. The heat sink 7 is an aluminum alloy sheet. The heat generated by the LED lamp beads 3 will be transmitted to the substrate 1 through the lamp holder 2. The substrate 1 will transfer the heat to the heat sink 7. The heat sink 7 can improve the heat dissipation effect of the substrate 1, thereby cooling the LED lamp beads 3 and ensuring that the LED lamp beads 3 can continuously work normally.

[0030] As Figure 2 and Figure 3As shown, a plurality of fins 8 are welded to the surface of the heat sink 7. The fins 8 are made of aluminum alloy sheets. The fins 8 can increase the contact area between the heat sink 7 and the air, thereby improving the heat dissipation effect of the heat sink 7. A plurality of heat conducting rods 10 are fixedly connected inside the substrate 1. The heat conducting rods 10 are fixedly connected to the heat sink 7. The heat conducting rods 10 are made of copper alloy rods. The heat conducting rods 10 can transfer the heat inside the substrate 1 to the heat sink 7 faster, thereby evenly cooling the substrate 1. A clamping strip 9 is fixedly connected to the surface of the heat sink 7. The clamping strip 9 is fixedly connected to the substrate 1. The clamping strip 9 can improve the connection strength between the heat sink 7 and the substrate 1, ensuring that the heat sink 7 can work properly. A current limiting frame 11 is fixedly connected to the surface of the substrate 1. The pin 4 is located inside the current limiting frame 11. An inner partition 12 is fixedly connected to the inner wall of the current limiting frame 11. The inner partition 12 is fixedly connected to the substrate 1. The cooperation of the current limiting frame 11 and the inner partition 12 can prevent the molten solder from overflowing, avoiding the occurrence of a short circuit caused by the solder contacting other circuits on the circuit board.

[0031] The overall working principle is as follows. When using the surface-mounted LED lamp, it is necessary to use solder to weld the pin 4 on the circuit board. During the welding process, the protective cover 6 adhered to the surface of the lamp holder 2 with non-drying glue can shield and protect the convex lens 5, preventing the convex lens 5 from being scratched during the welding process. The cooperation of the current limiting frame 11 and the inner partition 12 can prevent the molten solder from overflowing, avoiding the occurrence of a short circuit caused by the solder contacting other circuits on the circuit board. When the LED lamp bead 3 works, the convex lens 5 can converge the light emitted by the LED lamp bead 3, thereby increasing the brightness intensity of the LED lamp bead 3. Furthermore, it is possible to clearly view the display screen located at a long distance or installed at a high altitude. The heat generated by the LED lamp bead 3 will be transferred to the substrate 1 through the lamp holder 2. The substrate 1 will transfer the heat to the heat sink 7. The heat sink 7 can improve the heat dissipation effect of the substrate 1, thereby cooling the LED lamp bead 3 to ensure that the LED lamp bead 3 can continue to work properly. The fins 8 can increase the contact area between the heat sink 7 and the air, thereby improving the heat dissipation effect of the heat sink 7. The heat conducting rods 10 can transfer the heat inside the substrate 1 to the heat sink 7 faster, thereby evenly cooling the substrate 1. The clamping strip 9 can improve the connection strength between the heat sink 7 and the substrate 1, ensuring that the heat sink 7 can work properly.
