Description

Technical Field

[0001] The utility model relates to the technical field of LED lamp beads, and in particular to a chip-type lamp bead structure capable of emitting multi-color light. Background Art

[0002] With the continuous deepening of science and technology and environmental protection concepts, LED lamp beads have become the mainstream choice of the global lighting and display industry with their incomparable advantages. LED lamp beads perform well in energy saving, and their energy consumption is much lower than that of traditional lighting sources. Their long life and short response time make them widely used in many scenarios, from ordinary lighting in homes and commercial places to advanced lighting solutions for automotive interiors and exteriors, from high-definition display of large display screens to precise control of traffic signal indication systems, and to the delicate performance of backlighting of consumer electronic products, LED lamp beads play a key role in them.

[0003] When currently LED chips are packaged, the packaging glue used for packaging cannot flow toward the electrode sheets on both sides of the LED lamp bead holder due to multiple factors such as packaging effect, current transmission and pin hole smoothness. It can only flow in the direction perpendicular to the electrode sheets on both sides. This ensures that the packaging glue covers the surface of the LED chip to form an effective protective layer, while avoiding affecting the current transmission and the smoothness of the pin holes.

[0004] Since the electrode sheet of the LED lamp bead holder is distributed in half, the single or multiple LED chips installed on the electrode sheet can only be packaged in a unified way during dispensing packaging. Once multiple LED chips are packaged separately, the gold wire used to weld the LED chip to the electrode sheet will be exposed outside the packaging material, which can easily cause damage. This means that no matter how many LED chips are installed on the electrode sheet, they will be covered by the same packaging material and cannot be packaged separately. The same packaging material only uses one color, which results in an LED lamp bead only emitting one color of light and not multi-color light.

[0005] The purpose of the utility model is to solve the problem that the electrode sheet layout of the current chip-type lamp bead bracket is distributed in half, so that a single or multiple LED chips installed on the electrode sheet can only be packaged uniformly during dispensing packaging, and multiple LED chips on the electrode sheet cannot be packaged separately, so that an LED lamp bead can only emit light of one color and cannot emit multi-color light. Utility Model Content

[0006] In order to solve the problem that the electrode sheet layout of the current chip-type lamp bead holder is half-distributed, so that the single or multiple LED chips installed on the electrode sheet can only be packaged uniformly during dispensing packaging, and the multiple LED chips on the electrode sheet cannot be packaged separately, so that one LED lamp bead can only emit one color of light and cannot emit multi-color light, the utility model adopts the following technical solutions:

[0008] The bracket is used to provide physical support and electrical conduction basis for the entire lamp bead;

[0009] The electrode mechanism is fixedly connected to the top surface of the bracket, and the electrode mechanism is used to transmit the current signal, and the electrical signal supplied by the external power supply is guided to the light-emitting mechanism through the electrode mechanism;

[0010] The electrode mechanism comprises a first electrode sheet and a second electrode sheet, wherein the first electrode sheet is fixedly connected to one side of the top surface of the bracket, and the second electrode sheet is fixedly connected to the other side of the top surface of the bracket, and the first electrode sheet and the second electrode sheet are arranged in a nested manner;

[0011] The light-emitting mechanism is fixedly connected to the top surface of the electrode mechanism, the light-emitting mechanism is used to emit multi-color light, and the light-emitting mechanism is electrically connected to the electrode mechanism.

[0012] In the chip-type lamp bead structure capable of emitting multi-color light as described above, the overall shapes of the first electrode sheet and the second electrode sheet are both L-shaped.

[0013] In the chip-type lamp bead structure capable of emitting multi-color light as described above, one end of the first electrode sheet faces one side of the second electrode sheet, the other side of the second electrode sheet faces the other end of the first electrode sheet, and the first electrode sheet and the second electrode sheet are surrounded to form a U-shape.

[0014] As described above, a chip-type lamp bead structure capable of emitting multi-color light, the light-emitting mechanism includes a plurality of packaging mechanisms, the packaging mechanisms include LED chips and packaging materials, a plurality of the LED chips are fixedly connected to the top surfaces of the first electrode sheet and the second electrode sheet, the packaging material is fixedly connected above the LED chips, the packaging material is fixedly connected to the bracket, and the packaging material is used to cover and protect the LED chips.

[0015] In the chip-type lamp bead structure capable of emitting multi-color light as described above, a plurality of the LED chips are connected in parallel.

[0016] In the chip-type lamp bead structure capable of emitting multi-color light as described above, the packaging material is a transparent epoxy resin, and the packaging material is mixed with colored fluorescent powder.

[0017] As described above, in a chip-type lamp bead structure capable of emitting multi-color light, the outer corner sides of the first electrode sheet and the second electrode sheet are fixedly connected with protrusions, and the protrusions are used to increase the number of contact points and adhesion between the first electrode sheet and the second electrode sheet and the bracket.

[0018] As described above, in a chip-type lamp bead structure capable of emitting multi-color light, grooves are provided on the inner corner sides of the first electrode sheet and the second electrode sheet, and the grooves are used to improve the adhesion between the packaging material and the first electrode sheet and the second electrode sheet.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] 1. In the present utility model, the design of the electrode mechanism breaks through the limitation of the half-distribution of the electrode pieces of the traditional LED lamp bead bracket. The electrode mechanism includes a first electrode piece and a second electrode piece. The two electrode pieces are not simply distributed on both sides of the bracket, but are arranged in a mutually nested and staggered manner. This layout design not only optimizes the space utilization, so that multiple LED chips can be installed on a limited bracket area, but also provides the possibility of packaging each LED chip separately.

This innovative design greatly improves production efficiency, reduces the number of lamp beads installed, and directly reduces the material cost of the light string. At the same time, due to the reduction in the number of lamp beads, the welding points and potential failure points are also halved accordingly, which not only simplifies the production process, but also significantly improves the overall yield and reliability of the light string;

[0022] In summary, the utility model solves the problem that the electrode sheet layout of the current chip-type lamp bead holder is distributed in half, so that a single or multiple LED chips installed on the electrode sheet can only be packaged uniformly during dispensing packaging, and multiple LED chips on the electrode sheet cannot be packaged individually, so that an LED lamp bead can only emit light of one color and cannot emit multi-color light.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] like Figures 1 to 3 As shown, the utility model proposes a chip-type lamp bead structure capable of emitting multi-color light, comprising a bracket 1, an electrode mechanism 2 and a light-emitting mechanism 3;

[0031] The bracket 1 is used to provide physical support and electrical conduction basis for the entire lamp bead.

[0032] The electrode mechanism 2 is fixedly connected to the top surface of the bracket 1. The electrode mechanism 2 is used to transmit current signals. The electrical signals supplied by the external power supply are guided to the light-emitting mechanism 3 through the electrode mechanism 2. The electrode mechanism 2 includes a first electrode sheet 201 and a second electrode sheet 202. The first electrode sheet 201 is fixedly connected to one side of the top surface of the bracket 1, and the second electrode sheet 202 is fixedly connected to the other side of the top surface of the bracket 1. The first electrode sheet 201 and the second electrode sheet 202 are nested in each other. The overall shape of the first electrode sheet 201 and the second electrode sheet 202 is L-shaped. One end of the first electrode sheet 201 is arranged on one side of the second electrode sheet 202, and one end of the second electrode sheet 202 is arranged on one side of the first electrode sheet 201.

[0033] The light-emitting mechanism 3 is fixedly connected to the top surface of the electrode mechanism 2. The light-emitting mechanism 3 is used to emit multi-color light. The light-emitting mechanism 3 is electrically connected to the electrode mechanism 2. The light-emitting mechanism 3 includes a plurality of packaging mechanisms 301. The packaging mechanisms 301 include LED chips 302 and packaging materials 303. The plurality of LED chips 302 are fixedly connected to the top surfaces of the first electrode sheet 201 and the second electrode sheet 202. The plurality of LED chips 302 are in a parallel relationship. The packaging material 303 is fixedly connected above the LED chip 302. The packaging material 303 is fixedly connected to the bracket 1. The packaging material 303 is used to cover and protect the LED chip 302. The packaging material 303 is a transparent epoxy resin, and the packaging material 303 is mixed with colored fluorescent powder.

[0034] When the external power supply is turned on, the current enters the bracket 1 through the pins or connecting wires of the LED lamp bead. The bracket 1 not only provides physical support for the entire lamp bead structure, but also serves as the basis for electrical conduction to evenly distribute the current to the first electrode sheet 201 and the second electrode sheet 202.

[0035] The design of the electrode mechanism 2 breaks through the limitation of the half-distribution of the electrode sheets of the traditional LED lamp bead bracket. Specifically, the electrode mechanism 2 includes a first electrode sheet 201 and a second electrode sheet 202. The two electrode sheets are not simply distributed on both sides of the bracket 1, but are arranged in a mutually nested and staggered manner. This layout design not only optimizes the space utilization, so that multiple LED chips can be installed on the limited area of ​​the bracket 1, but also provides the possibility of individually encapsulating each LED chip. Because each LED chip can be independently connected to the electrode sheet part adjacent to it, the gold wire used for welding the electrode sheet will not be exposed outside the packaging material after individual packaging. This individual packaging method also makes full use of the existing packaging technology. By adjusting the spacing between the packaging flow channels of the packaging mold, the packaging of LED chips with different spacings can be achieved without major improvements or upgrades to the existing packaging technology. This not only reduces production costs, but also improves production efficiency, making this new LED lamp bead structure more competitive in practical applications.

[0036] These LED chips 303 are installed in parallel and can independently draw current from the electrode sheet and emit light of a specific color according to their own characteristics. The advantage of this parallel structure design is that even if a single LED chip 302 has a problem, it will not affect the normal operation of other chips, thereby improving the reliability and flexibility of the overall system. If multiple LED chips 302 are connected in series, gold wire is required to connect the multiple LED chips 302 in series when the LED chips 302 are installed upright. Since there is gold wire between the LED chips 302, it is impossible to achieve a separate package of a single LED chip 302. When the LED chip 302 is flipped, that is, the electrode of the LED chip 302 is directly in contact with the electrode sheet, multiple LED chips 302 cannot be connected in series.

[0037] When the LED chip 302 emits light, the emitted light passes upward through the packaging material 303. The packaging material 303 is usually composed of a transparent epoxy resin with colored phosphors mixed inside. The phosphors can absorb part of the light emitted by the LED chip 302 and re-radiate colored light. Therefore, inside the packaging material 303, the original light of the LED chip 302 and the light converted by the phosphors are superimposed and mixed, forming a richer and softer color effect.

[0038] The original light of the LED chip 302 of a single packaging mechanism 301 is mixed and diffused by the packaging material 303 to form colored monochromatic light. Since the electrode mechanism 2 is connected in parallel with several packaging mechanisms 301, different packaging mechanisms 301 can emit different colors according to different phosphors, so that an LED lamp bead can form a visible multi-color light effect. This multi-color light can be used for various lighting and indication applications to provide a colorful atmosphere and visual effects for the environment.

[0039] The luminous color of the LED chip 302 and the type and ratio of the phosphor in the packaging material can be adjusted according to specific needs to achieve different multi-color light effects.

[0040] like Figure 2 As shown, the outer corners of the first electrode sheet 201 and the second electrode sheet 202 are fixedly connected with protruding pieces 203 , and the protruding pieces 203 are used to increase the number of contact points and adhesion between the first electrode sheet 201 and the second electrode sheet 202 and the bracket 1 .

[0041] The protrusion 203 increases the number of contact points between the electrode sheet and the bracket 1, making the contact between the first electrode sheet 201 and the second electrode sheet 202 and the bracket 1 closer, increasing the conductive contact area, and helping to improve the stability of current transmission and reduce resistance loss. The presence of the protrusion 203 enhances the mechanical connection strength between the first electrode sheet 201 and the second electrode sheet 202 and the bracket 1, and enhances the adhesion of the first electrode sheet 201 and the second electrode sheet 202.

[0042] like Figure 3 As shown, grooves 204 are formed at the inner corners of the first electrode sheet 201 and the second electrode sheet 202 . The grooves 204 are used to improve the adhesion between the packaging material 303 and the first electrode sheet 201 and the second electrode sheet 202 .

[0043] The presence of the groove 204 enables the packaging material 303 to be better embedded in the groove 204 of the electrode sheet, thereby enhancing the mechanical interlocking force between the packaging material 303 and the electrode sheet, improving the adhesion between the packaging material 303 and the electrode sheet, and ensuring the stability of the packaging.

[0044] For example, Figures 4 to 5 As shown, conventional LED lamp beads usually adopt an electrode structure designed in half, that is, an anode and a cathode are located on opposite sides of the bracket 1. When the LED chip is installed in the upright position, it is installed on the electrode sheet on one side. In order to energize the LED chip, a gold wire must be used to connect the electrode of the LED chip to the corresponding electrode sheet. At this time, one end of the gold wire crosses the insulating tape from the electrode sheet on one side and is connected to the electrode sheet on the other side. When packaging the LED chip, the gold wire needs to be packaged as well. Therefore, no matter how many LED chips are installed on the electrode sheet or which side of the electrode sheet the LED chip is installed on, when packaging, the packaging material must cover When the LED chip is flipped, there is no need to use gold wire to solder the LED chip and the electrode sheets. However, the positive and negative electrodes of the LED chip need to contact the electrode sheets on both sides respectively. Therefore, when the LED chip is flipped, the LED chip needs to be installed between the two electrode sheets. Due to the limitation of the installation position of the LED chip, when the flipped LED chip is packaged, no matter how many LED chips are installed on the bracket, they will be covered by the same packaging material. In summary, the design of traditional electrode sheets often makes a single LED lamp bead can only encapsulate and activate one color of phosphor, so that the light emitted by each chip is of a single color.

[0045] In the chip-type lamp bead capable of emitting multi-color light of the present application, the first electrode sheet 201 and the second electrode sheet 202 are not simply arranged in half, but are nested in each other and arranged on both sides of the bracket 1, and a plurality of separately packaged LED chips 302 can be fixed and connected to each electrode sheet, and each separately packaged LED chip 302 can emit different light according to the color of the packaging material 303. The advantage of such a design is that separately packaged LED chips 302 of multiple colors can be integrated into the same LED lamp bead, and they are connected in parallel, which means that each LED chip 302 can be lit independently. When packaging the LED chips 302, packaging glues of different colors can respectively package different LED chips 302, thereby achieving light of different colors in the same lamp bead or producing more color effects through mixing.

[0046] Specifically, the working principle of the utility model is as follows:

[0047] When the external power supply is turned on, the current enters the bracket 1 through the pins or connecting wires of the LED lamp beads, and the current is evenly distributed to each LED chip 302 through the first electrode sheet 201 and the second electrode sheet 202. Each LED chip 302 can independently draw current from the electrode sheet and emit light. Even if a single LED chip 302 has a problem, it will not affect the normal operation of other chips, thereby improving the reliability and flexibility of the overall system. When the LED chip 302 emits light, the emitted light passes upward through the packaging material 303. The packaging material 303 is usually composed of a transparent epoxy resin with a mixture of colored fluorescent powder inside. The fluorescent powder can absorb part of the light emitted by the LED chip 302 and re-radiate colored light.

[0048] The original light of the LED chip 302 of a single packaging mechanism 301 is mixed and diffused by the packaging material 303 to form colored monochromatic light. Since the electrode mechanism 2 is connected in parallel with several packaging mechanisms 301, different packaging mechanisms 301 can emit different colors according to different phosphors, so that an LED lamp bead can form a visible multi-color light effect. This multi-color light can be used for various lighting and indication applications to provide a colorful atmosphere and visual effects for the environment.

[0049] In summary, the utility model solves the problem that the electrode sheet layout of the current chip-type lamp bead bracket is half-distributed, so that a single or multiple LED chips installed on the electrode sheet can only be packaged uniformly during dispensing packaging, and multiple LED chips on the electrode sheet cannot be packaged separately, so that an LED lamp bead can only emit light of one color, and cannot emit multi-color light.
