Description

Technical Field

[0001] The invention relates to the technical field of lamp beads, in particular to an RGB-LED lamp bead based on polycrystalline series connection. Background Art

[0002] RGB-LED lamp beads are LED lamps that can emit red, green and blue light, that is, light-emitting diodes. These lamp beads are often used in display and lighting applications, especially in situations where color changes and full-color displays are required. Polycrystalline series RGB-LED lamp beads are composed of multiple LED chips connected in series.

[0003] In the process of series connection, since the light emitted is the three primary colors of red, green and blue, and the resistance of each lamp bead is different, in the series circuit, the brightness of each lamp bead cannot be the same under equal voltage, so when the RGB light is switched, it will cause alternating light and dark, which will cause certain damage to the human eyes. In addition, the color of RGB light requires very precise wavelength and brightness matching. In order to display different colors after mixing, RGB-LED lamp beads of different colors need to be adjusted to specific wavelengths and brightness, so as to achieve a stable color mixing effect.

[0004] In order to solve the above problems, a variety of solutions have been proposed in the prior art, including a high-voltage five-color LED lamp bead with patent number 202311020032.3, which uses 9 blue light chips in series, 9 green light chips in series, and 13 red light chips in series to achieve voltage balance for the five kinds of light of RGB three colors and positive warm white two colors, so that when the voltages of the red, green and blue lamp beads are different due to different resistance values, the voltage of the overall circuit can be properly adjusted, thereby ensuring the brightness of the RGB lamp beads during normal operation. However, when it is necessary to adjust the color of the lamp bead light, it is still necessary to disassemble the outer shell and change the internal series circuit, or replace other lamp beads. During the normal use of the integrated LED lamp beads, it is not convenient to replace them, and it is difficult for users to change the internal circuit when adjustment is required, and thus it is difficult to change the color and brightness of the lamp beads.

[0005] Based on this, in order to solve the problem of how to easily change the color of the lamp beads while ensuring the brightness of the lamp beads, the present invention designs an RGB-LED lamp bead based on polycrystalline series connection. Summary of the invention

[0006] The present 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 chips of different colors connected to the circuit in the circuit, the intensity of the emitted light is synchronously controlled, and the intensity of the light emitted by the lamp bead is simultaneously improved when adjusting the light color to brighten it.

[0009] Preferably, the mounting seat is divided into an R seat, a G seat and a B seat, and there are 9 chips on the R seat and the G seat, and there are 13 chips on the B seat. By setting the above method, the voltages of the three chips of RGB are balanced, and the problem of poor power matching caused by different voltages of red, green and blue light is solved, so that a high-voltage single-power RGB-LED lamp bead is made; when all the chips are not used, the color and brightness of the three-color mixture are changed by changing the number of chip connection circuits, and the current is transmitted from the external power supply to the B seat through the wire, and then flows to the G seat after passing through the B seat, and finally flows to the shaft through the R seat to form a closed-circuit current.

[0010] Preferably, the R seat, G seat and B seat are all equipped with a conductive layer and an insulating layer, and a rotating shaft is installed at the center of the shell. The conductive layer is electrically connected to the rotating shaft. The conductive layers are not directly connected to each other to avoid bypassing the chip and directly connecting to the power supply. The insulating layer is to avoid the formation of a parallel circuit in a ring. Under the setting of the insulating layer, the current flows through the conductive layer, passes through the chip, and finally flows to the next layer of the mounting seat or the rotating shaft, thereby realizing the circuit cycle.

[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 elastic material, and has a mesh structure when unfolded; the surface of the thin film layer is coated with fluorescent powder, and the outer surface of the lens is arc-shaped; the fluorescent powder is used to add a layer of "fog" to the light, thereby forming a hazy mood and reducing the irradiation angle of the light; and when the surface of the thin film layer is unfolded, the rotating lens will gradually make the thin film layer 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 to the surroundings is blocked by the thin film layer, and the fluorescent powder increases the emission range of the light, thereby increasing the light intensity.

[0014] Preferably, the end of the telescopic block is a conical structure, a contact head is installed on the conical 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 achieve limiting of the telescopic block and the mounting seat on the other hand.

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

[0016] 1. The present invention proposes an RGB-LED lamp bead based on polycrystalline series connection. During the rotation of the rotating ring, the circuit can be adjusted so that the circuit connects chips of different colors and different numbers, thereby mixing to form lights of different colors and brightness. When a stable voltage is required, it can be adjusted to connect all the chips, thereby achieving a circuit of 9 red chips, 9 green chips and 13 blue chips in series, thereby achieving each chip to emit the maximum brightness; at the same time, under the action of the adjustment mechanism, the clarity of the scattered light is changed. As the color of the light gradually increases, the clarity is also gradually increased. On the one hand, the bright color can be clearer, and the dark color can be hazy, thereby expanding the use of the lamp bead, and on the other hand, the convenience of the lamp bead in switching brightness and color is improved.

[0017] 2. The present invention proposes an RGB-LED lamp bead based on polycrystalline series connection. As the a rod rotates, the b rod and the c rod will rotate synchronously under the action of the unidirectional rotating member, so that the R seat and the a rod can move relative to each other, and then the a rod can be used to adjust the number of red chips connected to the R seat; when the inner ring stops rotating, the position of the G seat is limited by the inner ring, so as to facilitate the adjustment of the number of green chips on the G seat connected to the wire; similarly, the number of other chips connected to the circuit can be adjusted, so as to achieve the convenience and accuracy of light color adjustment.

[0018] 3. The present invention proposes an RGB-LED lamp bead based on polycrystalline series connection.

At this time, the c-rod will drive the rotating lens to transmit in the positive direction. The film layer in the initial position is overlapped and misaligned, and gradually resets after rotation. On the one hand, it reduces the obstruction and reflection of light, thereby improving the brightness of the light. On the other hand, it allows the light to flow out in the desired irradiation direction, reduces the scattering of light, and can directly irradiate when bright light is required, thereby improving the light intensity of the lamp bead.

DETAILED DESCRIPTION

[0028] In order to better understand the above solution, the above technical solution is described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] like Figure 1-2As shown, the present invention provides an RGB-LED lamp bead based on polycrystalline series connection, which is mainly aimed at large lamp beads. It has a certain cost. Therefore, when the light needs to be replaced, the light color is often adjusted by adjusting the number of connected chips after disassembly, including a shell 1, a bracket 2, a mounting seat 3, a swivel 4, a driving mechanism 5, a lens 6, an adjustment mechanism 7 and a rotating lens 8. The bracket 2 is installed on the shell 1. The bracket 2 is used to support the mounting seat 3 and store wires to facilitate the placement and winding of the wires. The mounting seat 3 is installed above the shell 1. A plurality of the mounting seats 3 are located between the brackets 2. The mounting seat 3 is used to install chips. The number of chips is set to multiple, and the mounting seats 3 are arranged in different areas from the outside to the inside. The blue chip, the green chip and the red chip are arranged in sequence, and the RGB-LED lamp beads are illuminated through circuit connection, thereby achieving the lighting effect; the rotating ring 4 is installed below the mounting seat 3, the driving mechanism 5 is located at the rotating ring 4, the lens 6 is installed above the housing 1, the adjusting mechanism 7 is located between the lens 6 and the rotating ring 4, 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 rotating ring 4 rotates to drive the driving mechanism 5, the driving mechanism 5 adjusts the number of current passing through chips of different colors, the adjusting mechanism 7 changes the rotation angle of the rotating lens 8 under the action of the driving mechanism 5, and 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 in the circuit can be adjusted to form lights of different colors. When a stable voltage is required, it can be adjusted to connect all the chips, thereby achieving a circuit of 9 red chips, 9 green chips and 13 blue chips in series, so that each chip can emit the maximum brightness. During the rotation of the rotating ring 4, the number of chips of different colors can be adjusted by the rotating ring 4 at different positions. At the same time, under the action of the adjusting mechanism 7, the clarity of the scattered light is changed. As the color of the light gradually increases, the clarity is also gradually increased, so that the bright color can be clearer, and the dark color can appear hazy, thereby expanding the use of the lamp beads and improving the convenience of the lamp beads in switching brightness and color.

[0031] like Figure 3 As shown, the mounting seat 3 is divided into an R seat 31 , a G seat 32 and a B seat 33 . There are 9 wafers on the R seat 31 and the G seat 32 , and there are 13 wafers on the B seat 33 .

[0032] The RGB lamp beads on the market are used in combination of single chips. The voltage of the red chip inside is usually around 2.0v, while the voltage of the green and blue chips is around 3.0v. As a result, the voltage of the three colors of the RGB lamp beads is inconsistent. When using them, other components need to be assembled for use (mounting resistors, adding adapter power supplies), which causes a lot of inconvenience and increases the cost of use. By setting the above method to balance the voltages of the three RGB chips, the problem of poor power matching caused by different red, green and blue light voltages is solved. When three-color mixing is required, the voltage of each color is guaranteed to be stable under maximum power, thereby achieving the effect of full luminescence.

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

[0034] The current is connected to the chips of various colors on the mounting seat 3 through wires. Under the action of the current, the chips emit light, and the current flows along the conductive layer 34 to the inner rotating ring 4, and then to the chips of the next color, and then passes through the conductive layer 34 again to reach the chips of the next color, and finally realizes the circuit circulation through the rotating shaft 11. During the rotation process, the insulating layer 35 is used to block the circuit on the one hand, and to avoid circuit breaking on the other hand, thereby reducing the problem of circuit damage.

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

[0036] By toggling the driving rod 51, the driving 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 card slot 54, and thus a complete circuit cannot be formed inside. When the telescopic block 52 moves to the card slot 54, it is affected by the compression spring 53 and extends out, and then embedded in the card slot 54 to form a complete current loop. At this time, the required RGB-LED lamp beads can be formed after power is turned on. In this process, as the driving rod 51 rotates, the position of the card slot 54 where the telescopic block 52 is embedded is different, and thus the number of chips in the circuit is different, which affects the brightness of the light. At the same time, lights of different colors can be adjusted, thereby changing the process of replacing the circuit when switching lights in traditional lamp beads, thereby improving the convenience of switching lights in the lamp beads.

[0037] The rotating ring 4 is divided into an inner ring 41, a middle ring 42 and an outer ring 43, and the driving rod 51 is divided into an a rod 511, a b rod 512 and a c rod 513. The a rod 511 is connected to the inner ring 41, the b rod 512 is connected to the middle ring 42, and the c rod 513 is connected to the outer ring 43. The inner ring 41, the middle ring 42 and the outer ring 43 are connected via 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. With the rotation of the a rod 511, the b rod 512 and the c rod 513 will rotate synchronously under the action of the one-way rotating member 9, so that only the R seat 31 and the a rod 511 move relative to each other, and 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 limited 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 too limited. Here, a method is proposed, which can achieve extrusion of the magnet by pressing, thereby limiting the G seat 32, so as to facilitate the adjustment of the number of green chips on the G seat 32 connected to the wire;

[0039] When the b-rod 512 rotates, the b-rod 512 will drive the middle ring 42 to rotate. Under the linkage of the one-way rotating member 9, the b-rod 512 will synchronously drive the outer ring 43 to rotate. At this time, the G-base 32 is fixed relative to the inner ring 41, and then the telescopic rod on the middle ring 42 will be stuck in the slot 54 on the G-base 32, thereby limiting the green chips connected to the line on the G-base 32; after the b-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 required for adjustment, thereby achieving the accuracy of light color adjustment.

[0040] Finally, the c-rod 513 rotates, and the rotation of the c-rod 513 drives the inner ring 41 to rotate. Under the linkage of the one-way rotating member 9, the c-rod 513 drives the outer ring 43 to rotate. At this time, the b-rod 512 limits the position of the R seat 31. The b-rod 512 adjusts the number of red chips in the circuit through the telescopic block 52, thereby improving the convenience and accuracy of three-color light mixing.

[0041] like Figure 5-6 As shown, the one-way rotating member 9 includes a pawl 91, a return spring 92, and a ring tooth 93. The pawl 91 is respectively installed on the inner walls 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 walls 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 the a-rod 511, during the rotation of the inner ring 41, through the engagement of the pawl 91 and the ring tooth 93, when the a-rod 511 drives the inner ring 41 to rotate, the inner ring 41 drives the middle ring 42 to rotate, thereby realizing synchronous rotation. The same applies to the outer ring 43, so that the innermost red chip can be adjusted first, followed by the green chip, and finally the blue chip. During the adjustment process, even if the adjustment is too much, it can be adjusted in the opposite direction. Due to the setting of the pawl 91 and the ring tooth 93, the opposite directions will not be correlated with each other, so that the effect of independent adjustment can be achieved, thereby improving the convenience of lamp 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 mirror 8 . The thin film layer 72 is installed in an array between the rotating mirror 8 and the lens 6 .

[0044] During the rotation of the a-rod 511, since the inner ring 41 will synchronously drive the middle ring 42 and the outer ring 43 to rotate, and then drive the c-rod 513 to rotate, as long as the a-rod 511 is rotating in the positive direction, the c-rod 513 will drive the connecting rod 71 to rotate in the positive direction, and then drive the rotating lens 8 to transmit in the positive direction. The film layer 72 is overlapped in the initial position and gradually resets after the rotation. On the one hand, it reduces the penetration of light and increases the zero degree of light. On the other hand, it allows the light to flow out in the desired direction of irradiation, reduces the scattering of light, and can directly irradiate when bright light is required, and can provide a reasonable light intensity when the lamp beads need strong light, and can provide a hazy feeling when the lamp beads need dim light.

[0045] like Figure 2 , 7 As shown, the film layer 72 is made of elastic material, and has a mesh structure when unfolded.

[0046] The film layer 72 is initially an unfolded mesh structure, but in the initial state the mesh structures are intertwined to form a shielding shape. At this time, there are fewer chips connected in series in the lamp bead, and a dim environment needs to be created. The film layer 72 can improve the controllability of the light.

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

[0048] In the unfolded state, the fluorescent powder is used to add a layer of "fog" to the light, thereby creating a hazy mood and reducing the angle of light irradiation; when the surface of the film layer 72 is unfolded, the rotating lens 8 will gradually make the film layer 72 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 to the surroundings is blocked by the film layer 72, and the fluorescent powder increases the emission range of the light, thereby increasing the light intensity.

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

[0050] The telescopic block 52 with a conical structure can realize bidirectional adjustment on the left and right sides, and then the rotation angle of the swivel 4 can be adjusted clockwise and counterclockwise through the driving rod 51, so that the contact head 521 is embedded in the groove, and 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 realize limiting, thereby improving the stability after color adjustment.

[0051] When the color of the lamp beads needs to be adjusted, the driving rod 51 is adjusted in the positive direction, with the clockwise direction being the positive direction, and the driving rod 51 drives the rotating ring 4 to rotate, and the telescopic block 52 on the rotating ring 4 is gradually embedded in the card slot 54 at the bottom of the mounting seat 3, thereby forming a new complete circuit;

[0052] When the brightness of the red light needs to be increased, by rotating the a-rod 511, the a-rod 511 drives the inner ring 41 to rotate. At this time, the telescopic block 52 on the inner ring 41 will gradually squeeze the compression spring 53, and 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 is in the groove, thereby realizing normal connection of the circuit.

[0053] During the rotation of the a-rod 511, the a-rod 511 drives the inner ring 41 to rotate, and the inner ring 41 is affected by the one-way rotating member 9, and is transmitted to the middle ring 42 through the inner ring 41, and then to the outer ring 43. As the outer ring 43 rotates, the connecting rod 71 is driven, and the connecting rod 71 drives the rotating lens 8 to rotate, so that the film layer 72 is gradually transformed from the initial inclined state to the vertical state, so that sufficient light can be provided when the lamp bead needs bright colors;

[0054] During the rotation of the b-rod 512, the b-rod 512 will drive the middle ring 42 to rotate, and the middle ring 42 will drive the outer ring 43 to rotate through the one-way rotating member 9, and the green and blue lamp beads will be gradually adjusted. During the rotation, the pawl 91 on the middle ring 42 will contact the ring teeth 93 on the outer ring 43 when it rotates clockwise, so that the middle ring 42 will drive the outer ring 43 to rotate when it rotates in the positive direction. During the rotation of the outer ring 43, the rotating lens 8 will be driven to rotate through the connecting rod 71, and then the thin film layer 72 between the rotating lens 8 and the lens 6 will be driven from the stretched state to the normal vertical state, thereby synchronously improving the light intensity of the rotating lens 8.

[0055] The basic principles and beneficial effects of the present invention are shown and described above. At the same time, the present invention is not limited to the above embodiments. Without departing from the effects and scope of the present invention, the present invention may have various changes and improvements. These changes and improvements all fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
