Description

Technical Field

[0001] This invention relates to the field of LED technology, specifically to an RGB-LED LED based on polycrystalline series connection. Background Technology

[0002] RGB-LED beads are LEDs that emit red, green, and blue light; they are light-emitting diodes. These beads are commonly used in display and lighting applications, especially in situations requiring full-color display with varying colors. Polycrystalline RGB-LED beads consist of multiple LED chips connected in series.

[0003] During the series connection process, since the emitted light is in the three primary colors of red, green and blue, and each LED has a different resistance, under the same voltage in the series circuit, it is impossible for each LED to emit the same brightness. Therefore, when the RGB light switches, it will cause the phenomenon of alternating brightness, which can cause some damage to the eyes. In addition, the color of RGB light requires very precise wavelength and brightness matching. In order for different colors of RGB-LEDs to display different colors, they need to be adjusted to specific wavelengths and brightness to achieve a stable color mixing effect.

[0004] To address the aforementioned issues, existing technologies have proposed several solutions, including a high-voltage five-color LED bead with patent number 202311020032.3. This bead uses nine blue LED chips connected in series, nine green LED chips connected in series, and thirteen red LED chips connected in series to achieve voltage balance among the five colors (RGB, warm white, and neutral white). This allows for appropriate voltage adjustment of the overall circuit when the voltage of individual LED chips varies due to differences in resistance, thus ensuring the brightness of the RGB LEDs during normal operation. However, adjusting the color of the LED still requires disassembling the casing to modify the internal series circuit or replacing the LED chips. During normal use of integrated LED beads, replacement is inconvenient, and users find it difficult to modify the internal circuit when adjustments are needed, thus hindering the ability to change the color and brightness of the LED.

[0005] Therefore, in order to solve the problem of how to conveniently change the color of the LED while ensuring the brightness of the LED, this invention designs an RGB-LED LED based on polycrystalline series connection. Summary of the Invention

[0006] This invention provides an RGB-LED lamp bead based on polycrystalline series connection, which solves the problem of conveniently changing the color of the lamp bead while ensuring the brightness of the lamp bead; by changing the number of different color chips connected to the circuit, the intensity of the emitted light is controlled synchronously, thereby realizing the simultaneous increase of the intensity of the emitted light from the lamp bead when adjusting the brightness of the light color.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] This invention provides an RGB-LED lamp bead based on polycrystalline series connection, comprising a housing, a bracket, a mounting base, a rotating ring, a driving mechanism, a lens, an adjustment mechanism, and a rotating lens. The bracket is mounted on the housing, and the mounting base is mounted above the housing, with multiple mounting bases located between the brackets. The mounting base is used to mount the LEDs. The rotating ring is mounted below the mounting base, and the driving mechanism is located at the rotating ring. The lens is mounted above the housing, and the adjustment mechanism is located between the lens and the rotating ring. The rotating lens is mounted between the lens and the rotating ring and is rotatably connected to the lens. The rotation of the rotating ring drives the driving mechanism, which adjusts the number of LEDs of different colors through which current passes. The adjustment mechanism changes the rotation angle of the rotating lens under the action of the driving mechanism. The sharpness of the lens and the rotating lens is proportional to the number of LEDs. Through the synchronous cooperation of the driving mechanism and the adjustment mechanism, the light intensity gradually increases as the number of LEDs connected to the circuit increases.

[0009] Preferably, the mounting base is divided into an R-base, a G-base, and a B-base. The R-base and G-base have 9 chips, and the B-base has 13 chips. By setting up the above method, the voltage of the three RGB chips is balanced, which solves the problem of poor power supply matching caused by the different voltages of red, green, and blue light, and makes it a high-voltage single-power RGB-LED lamp bead. When not using all the chips, the color and brightness of the three-color mixing can be changed by changing the number of chip connection circuits. The current is delivered from the external power supply to the B-base through the wire, then flows to the G-base after passing through the B-base, and finally flows to the shaft through the R-base, forming a closed-loop current.

[0010] Preferably, conductive and insulating layers are installed on the R, G, and B seats, and a rotating shaft is installed at the center of the housing. The conductive layers are electrically connected to the rotating shaft. The conductive layers are not directly connected to each other to avoid bypassing the wafer and directly connecting to the power supply. The insulating layer is to prevent the formation of a parallel circuit in a ring. With the insulating layer, the current flows through the conductive layer, through the wafer, and finally to the next mounting seat or rotating shaft, thereby realizing the circulation of the circuit.

[0011] Preferably, the driving mechanism includes a driving rod, a telescopic block, a compression spring, and a slot. The driving rod is mounted on the rotating ring, the telescopic block is mounted on the top of the rotating ring, the compression spring is mounted between the telescopic block and the rotating ring, and the slot is located at the bottom of the mounting base corresponding to the telescopic block. The slots are arranged in an array to achieve forward and reverse adjustment. Simultaneously, during forward adjustment, the rotating lens can be driven synchronously. By adjusting the driving rod, the number of internally connected crystals can be adjusted without disassembling the outer casing. Therefore, when it is necessary to change the color and brightness, it can be achieved solely through the driving rod.

[0012] Preferably, the rotating ring is divided into an inner ring, a middle ring, and an outer ring, and the driving rod is divided into rod a, rod b, and rod c. Rod a is connected to the inner ring, rod b is connected to the middle ring, and rod c is connected to the outer ring. The inner ring, middle ring, and outer ring are connected by a one-way rotating component. The one-way rotating component includes a pawl, a return spring, and ring teeth. The pawl is installed on the inner wall of the middle ring and the outer ring, respectively. The return spring is installed between the pawl and the middle ring and between the pawl and the outer ring, respectively. The ring teeth are formed on the outer wall of the inner ring and the middle ring, and the ring teeth correspond to the pawl. The pawl and the ring teeth mesh with each other in the positive direction. In the opposite direction, the ring teeth push the pawl to compress the return spring, thus preventing synchronous movement. This allows for gradual adjustment of the number of connected wafers during the process of increasing the current, while simultaneously gradually adjusting the angle of the rotating lens.

[0013] Preferably, the adjustment mechanism includes a connecting rod and a thin film layer. The connecting rod is installed between the C-rod and the rotating lens, and the thin film layer array is installed between the rotating lens and the lens. The thin film layer is made of an elastic material and has a mesh structure when unfolded. The surface of the thin film layer is coated with phosphor, and the outer surface of the lens is arc-shaped. The phosphor is used to add a layer of "fog" to the light, thereby creating a hazy atmosphere and reducing the angle of light illumination. When the surface of the thin film layer is unfolded, the rotating lens gradually causes the thin film layer to transmit the light source along a straight line, thereby increasing the brightness of the light and reducing the refraction of the light. At the same time, the light scattered in all directions is blocked by the thin film layer, and the phosphor increases the range of light emission, thereby increasing the light intensity.

[0014] Preferably, the end of the telescopic block is a tapered structure, and a contact head is installed on the tapered surface of the telescopic block. The contact head is hemispherical, and a groove is provided on the inner wall of the slot corresponding to the contact head. The cooperation between the contact head and the groove can reduce current leakage on the one hand, and limit the telescopic block and the mounting base on the other hand.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. This invention proposes an RGB-LED lamp bead based on multi-crystal series connection. During the rotation of the ring, the circuit can be adjusted to connect different colors and numbers of chips, thereby mixing to form different colors and brightness of light. When a stable voltage is required, it can be adjusted to connect all chips, thus achieving a circuit with 9 red chips, 9 green chips, and 13 blue chips connected in series, thereby enabling each chip to emit maximum brightness. At the same time, under the action of the adjustment mechanism, the clarity of the emitted light is changed. As the light color gradually increases, the clarity also gradually increases. On the one hand, bright colors become clearer, while dark colors can appear hazy, thus expanding the application of the lamp bead. On the other hand, it improves the convenience of switching brightness and color of the lamp bead.

[0017] 2. This invention proposes an RGB-LED lamp bead based on multi-crystal series connection. As rod a rotates, rods b and c rotate synchronously under the action of the unidirectional rotating component, realizing the relative movement of the R-base and rod a. Thus, the number of red chips connected to the R-base can be adjusted through rod a. When the inner ring stops rotating, the position of the G-base is restricted by the inner ring, which facilitates the adjustment of the number of green chips connected to the wires on the G-base. Similarly, the number of other chips connected to the circuit can be adjusted, thus realizing the convenience and accuracy of light color adjustment.

[0018] 3. The present invention proposes an RGB-LED lamp bead based on polycrystalline series connection. During the rotation of rod a, the inner ring will synchronously drive the middle ring and outer ring to rotate, which will also drive rod c to rotate. At this time, rod c will drive the rotating lens to move in the positive direction. The thin film layer is initially overlapping and misaligned, and gradually resets after rotation. On the one hand, it reduces the obstruction and reflection of light, thereby improving the brightness of light. On the other hand, it allows light to flow out in the direction of required illumination, reducing the scattering of light. When the illumination needs to be bright, it can be directly shone, thereby improving the illumination intensity of the lamp bead. Attached Figure Description

[0028] To better understand the above solution, the technical solution will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1-2As shown, this invention provides an RGB-LED lamp bead based on multi-chip series connection, mainly targeting large lamp beads. Due to its cost, when replacing the light, the light color is often adjusted by disassembling and adjusting the number of connected chips. The invention includes a housing 1, a bracket 2, a mounting base 3, a rotating ring 4, a driving mechanism 5, a lens 6, an adjustment mechanism 7, and a rotating lens 8. The bracket 2 is mounted on the housing 1 and supports the mounting base 3, facilitating the placement and winding of the wires. The mounting base 3 is mounted on top of the housing 1, with multiple mounting bases 3 located between the brackets 2. Each mounting base 3 is used to mount chips, with multiple chips arranged in sections from the outside inwards. Blue, green, and red LED chips are arranged sequentially and connected by a circuit to make the RGB-LED beads emit light, thereby achieving the lighting effect. The rotating ring 4 is installed below the mounting base 3, the driving mechanism 5 is located at the rotating ring 4, the lens 6 is installed above the housing 1, the adjustment mechanism 7 is located between the lens 6 and the rotating ring 4, and the rotating lens 8 is installed between the lens 6 and the rotating ring 4. The rotating lens 8 is rotatably connected to the lens 6. The rotation of the rotating ring 4 drives the driving mechanism 5. The driving mechanism 5 adjusts the number of different colored chips through which the current passes. The adjustment mechanism 7 changes the rotation angle of the rotating lens 8 under the action of the driving mechanism 5. The clarity of the lens 6 and the rotating lens 8 is proportional to the number of chips.

[0030] During the rotation of the rotating ring 4, the number of chips of different colors connected to the circuit can be adjusted to form different colored lights. When a stable voltage is required, it can be adjusted so that all chips are connected, thus achieving a circuit with 9 red chips, 9 green chips and 13 blue chips connected in series, so that each chip can emit maximum brightness. During the rotation of the rotating ring 4, the number of chips of different colors can be adjusted by rotating the ring 4 at different positions. At the same time, under the action of the adjustment mechanism 7, the clarity of the emitted light is changed. As the color of the light gradually increases, the clarity also gradually increases, making bright colors clearer and dark colors appear hazy, thus expanding the application of the LED beads and improving the convenience of switching brightness and color.

[0031] like Figure 3 As shown, the mounting base 3 is divided into R base 31, G base 32 and B base 33. There are 9 chips on R base 31 and G base 32, and 13 chips on B base 33.

[0032] RGB LEDs on the market typically use a combination of single-chip chips. The red chip usually operates at around 2.0V, while the green and blue chips operate at around 3.0V. This results in inconsistent voltages for the three colors, requiring additional components (resistors, power adapters) for compatibility, causing inconvenience and increasing costs. The above method balances the voltages of the three RGB chips, resolving the power supply mismatch issue caused by the different red, green, and blue voltages. This ensures stable voltage for each color even at maximum power when three colors need to be mixed, achieving optimal illumination.

[0033] The R-base 31, G-base 32 and B-base 33 are each equipped with a conductive layer 34 and an insulating layer 35. A rotating shaft 11 is installed at the center of the housing 1, and the conductive layer 34 is electrically connected to the rotating shaft 11.

[0034] The current flows through wires to the chips of various colors on the mounting base 3. Under the action of the current, the chips emit light, and the current flows along the conductive layer 34 to the inner ring 4, then to the next color chip, and then through the conductive layer 34 again to the next color chip. Finally, the circuit is circulated through the rotating shaft 11. During the rotation, the insulating layer 35 serves to block the circuit on the one hand, and on the other hand, to prevent the circuit from being broken, thus reducing the problem of circuit damage.

[0035] like Figure 4 As shown, the drive mechanism 5 includes a drive rod 51, a telescopic block 52, a compression spring 53, and a slot 54. The drive rod 51 is mounted on the rotating ring 4, the telescopic block 52 is mounted on the top of the rotating ring 4, the compression spring 53 is mounted between the telescopic block 52 and the rotating ring 4, and the slot 54 is opened at the bottom of the mounting base 3 corresponding to the telescopic block 52. The slots 54 are arranged in an array.

[0036] By moving the drive rod 51, the drive rod 51 will drive the rotating ring 4 to rotate. During the rotation of the rotating ring 4, the telescopic block 52 is compressed by the compression spring 53. At this time, the telescopic block 52 is not embedded in the slot 54, so the internal circuit cannot be formed. When the telescopic block 52 moves to the slot 54, it is affected by the compression spring 53, and the telescopic block 52 extends and is embedded in the slot 54, forming a complete current loop. When energized, the required RGB-LED lamp bead can be formed. During this process, as the drive rod 51 rotates, the position of the telescopic block 52 embedded in the slot 54 is different, and the number of chips in the circuit is different, which affects the brightness of the light. At the same time, different colors of light can be adjusted, which changes the process of changing the circuit when switching the light in the traditional lamp bead, and improves the convenience of switching the light in the lamp bead.

[0037] The rotating ring 4 is divided into an inner ring 41, a middle ring 42 and an outer ring 43. The driving rod 51 is divided into rod a 511, rod b 512 and rod c 513. Rod a 511 is connected to the inner ring 41, rod b 512 is connected to the middle ring 42, and rod c 513 is connected to the outer ring 43. The inner ring 41, middle ring 42 and outer ring 43 are connected by a one-way rotating member 9.

[0038] The rotation of the inner ring 41 mainly adjusts the red chip on the innermost R seat 31, the rotation of the middle ring 42 adjusts the green chip on the G seat 32, and the rotation of the outer ring 43 adjusts the blue chip on the B seat 33. As the a rod 511 rotates, the b rod 512 and the c rod 513 will rotate synchronously under the action of the unidirectional rotating part 9, so that only the R seat 31 and the a rod 511 move relative to each other. Thus, the number of red chips connected to the R seat 31 can be adjusted by the a rod 511. When the inner ring 41 stops rotating, the position of the G seat 32 is restricted by the inner ring 41. The specific method is the existing technology, which can be a pin type or a magnetic type. The specific method is not limited. Here, a method is proposed to squeeze out the magnet by pressing, thereby restricting the G seat 32, so as to facilitate the adjustment of the number of green chips connected to the wires on the G seat 32.

[0039] When rod 512 rotates, it drives the middle ring 42 to rotate. Under the linkage of the unidirectional rotating component 9, rod 512 drives the outer ring 43 to rotate synchronously. At this time, the G-base 32 is fixed relative to the inner ring 41, and the telescopic rod on the middle ring 42 will be locked in the slot 54 on the G-base 32, thereby restricting the green chips connected to the circuit on the G-base 32. After rod 512 stops, the number of green chips between the slot 54 on the middle ring 42 and the conductive layer 34 is the number that needs to be adjusted, thus achieving accurate adjustment of the light color.

[0040] Finally, rod C513 rotates, which drives the inner ring 41 to rotate. Under the linkage of the unidirectional rotating component 9, rod C513 drives the outer ring 43 to rotate. At this time, rod B512 restricts the position of seat R31. Rod B512 adjusts the number of red chips in the circuit through telescopic block 52, thereby improving the convenience and accuracy of three-color mixing.

[0041] like Figure 5-6 As shown, the one-way rotating component 9 includes a pawl 91, a return spring 92, and a ring tooth 93. The pawl 91 is respectively installed on the inner wall of the middle ring 42 and the outer ring 43. The return spring 92 is respectively installed between the pawl 91 and the middle ring 42 and between the pawl 91 and the outer ring 43. The ring tooth 93 is opened on the outer wall of the inner ring 41 and the middle ring 42, and the ring tooth 93 corresponds to the pawl 91.

[0042] When the inner ring 41 is driven by rod 511, during the rotation of the inner ring 41, the engagement of pawl 91 and ring tooth 93 allows the inner ring 41 to rotate, which in turn drives the middle ring 42 to rotate, thus achieving synchronous rotation. The same applies to the outer ring 43. This allows for the adjustment of the innermost red chip first, followed by the green chip, and finally the blue chip. During the adjustment process, even if too much is adjusted, it can be adjusted in the opposite direction. Due to the design of pawl 91 and ring tooth 93, the opposite directions are not interconnected, thus achieving independent adjustment and improving the convenience of LED color adjustment.

[0043] The adjustment mechanism 7 includes a connecting rod 71 and a thin film layer 72. The connecting rod 71 is installed between the c-rod 513 and the rotating lens 8, and the thin film layer 72 is arrayed between the rotating lens 8 and the lens 6.

[0044] During the rotation of rod 511, the inner ring 41 will synchronously drive the middle ring 42 and the outer ring 43 to rotate, which will in turn drive rod 513 to rotate. Therefore, as long as rod 511 rotates in the positive direction, rod 513 will drive the connecting rod 71 to rotate in the positive direction, which will in turn drive the rotating lens 8 to move in the positive direction. The thin film layer 72 is initially overlapping and gradually resets after rotation. On the one hand, it reduces the penetration of light and thus increases the zero degree of light. On the other hand, it allows light to flow out in the direction of required illumination, reducing the scattering of light. When the illumination needs to be bright, it can shine directly, thus providing a reasonable light intensity when the lamp needs strong light, and providing a hazy feeling when the lamp needs dim light.

[0045] like Figure 2 , 7 As shown, the thin film layer 72 is made of an elastic material, and the thin film layer 72 unfolds into a mesh structure.

[0046] The thin film layer 72 is initially an unfolded mesh structure, but in the initial state the mesh structure is intertwined with each other, thus forming a shielding shape. At this time, there are few chips connected in series in the lamp bead, and a dim environment needs to be created. Therefore, the thin film layer 72 can be used to improve the controllability of the light.

[0047] The surface of the thin film layer 72 is coated with phosphor, and the outer surface of the lens 6 is arc-shaped.

[0048] In its undeployed state, the phosphor adds a layer of "fog" to the light, creating a hazy atmosphere and reducing the angle of light illumination. When the surface of the thin film layer 72 is deployed, the rotating lens 8 gradually causes the thin film layer 72 to transmit the light source along a straight line, thereby increasing the brightness of the light and reducing light refraction. At the same time, the light scattered in all directions is blocked by the thin film layer 72, and the phosphor increases the range of light emission, thereby increasing the light intensity.

[0049] The end of the telescopic block 52 is a tapered structure, and a contact head 521 is installed on the tapered surface of the telescopic block 52. The contact head 521 is hemispherical, and a groove is provided on the inner wall of the slot 54 corresponding to the contact head 521.

[0050] The tapered telescopic block 52 can achieve bidirectional adjustment on both the left and right sides. The rotation angle of the rotating ring 4 can be adjusted clockwise and counterclockwise by the drive rod 51, so that the contact head 521 is embedded in the groove. The contact point of the current is at the contact head 521 and the groove. On the one hand, it can reduce current leakage, and on the other hand, it can achieve limit and improve the stability after color adjustment.

[0051] When it is necessary to adjust the color of the LED beads, take the clockwise direction as the positive direction, adjust the drive rod 51 in the positive direction, the drive rod 51 drives the rotating ring 4 to rotate, and the telescopic block 52 on the rotating ring 4 gradually inserts into the slot 54 at the bottom of the mounting base 3, thereby forming a new complete circuit;

[0052] When it is necessary to increase the brightness of the red light, by rotating rod 511, rod 511 drives the inner ring 41 to rotate. At this time, the telescopic block 52 on the inner ring 41 will gradually squeeze and compress the spring 53. When the telescopic block 52 moves to the slot 54, it will pop out and then embed into the slot 54. The contact head 521 at the top of the telescopic block 52 and the groove will then achieve normal circuit connection.

[0053] During the rotation of rod 511, rod 511 drives the inner ring 41 to rotate. The inner ring 41 is affected by the unidirectional rotating part 9. The influence is transmitted from the inner ring 41 to the middle ring 42, and then from the middle ring 42 to the outer ring 43. As the outer ring 43 rotates, it drives the connecting rod 71, which in turn drives the rotating lens 8 to rotate. This causes the thin film layer 72 to gradually change from its initial inclined state to a vertical state, thus providing sufficient brightness when the lamp bead needs bright colors.

[0054] During the rotation of lever 512, lever 512 will drive the middle ring 42 to rotate. The middle ring 42 will drive the outer ring 43 to rotate through the one-way rotating part 9. At this time, the green and blue LED beads are gradually adjusted. During the rotation, the pawl 91 on the middle ring 42 will contact the ring tooth 93 on the outer ring 43 when it rotates clockwise. This will cause the middle ring 42 to rotate in the positive direction, which will drive the outer ring 43 to rotate. During the rotation of the outer ring 43, it will drive the rotating lens 8 to rotate through the connecting rod 71. This will cause the thin film layer 72 between the rotating lens 8 and the lens 6 to change from a stretched state to a normal vertical state, thereby simultaneously increasing the light intensity of the rotating lens 8.

[0055] The foregoing has shown and described the basic principles and beneficial effects of the present invention. However, the present invention is not limited to the above embodiments. Various changes and modifications can be made to the present invention without departing from its effects and scope. All such changes and modifications fall within the scope of the present invention as claimed, which is defined by the appended claims and their equivalents.
