Description

Technical Field

[0001] The utility model relates to the field of LED color lights, and particularly relates to a power carrier control lamp string with address codes. Background Art

[0002] At present, there appears on the market a "color light device triggered by multi-code mixed power line edge signals" (patent number: 202110041784.2). By randomly mixing and arranging several LED modules according to the address coding of the LED driving chip, a controllable random flashing function is realized. The random mixing and arranging method with address signals greatly reduces the difficulty of automatic production and processing of the whole lamp product and avoids the harsh requirements for the process when arranging in sequence. Further, through the address coding included in the LED module, an address signal can be generated by a power line edge signal generator to realize a controllable random flashing function.

[0003] The realization of a controllable random flashing function through the random mixing and arranging of a single LED module cannot adapt to application scenarios that require both regularity and randomness.

[0004] In some lighting application scenarios, such as the currently widely used LED meteor shower products in the market, such as the "LED meteor shower lamp" (application number 201410463105.0) records that "by controlling the LED lights arranged on the rigid PCB circuit board through a chip, the LED lights are like a meteor shower, bright, natural and smooth". For existing meteor shower products, a single-mode random effect is realized through the differences in the product control chips themselves (the differences in the operating frequencies of the control chips themselves).

[0005] With the development of technology, how to realize the random product effects of multiple controllable modes through power line carrier technology with high cost performance has good market application prospects. Content of the Utility Model

[0006] The purpose of the utility model is to provide a power carrier control lamp string with address codes. Through several groups of LED sub-strings, each LED sub-string includes several address-coded LEDs arranged in the order mode of address modulo M, and the product effects of multiple controllable modes can be realized through power line carrier technology with high cost performance.

[0007] A power carrier control lamp string with address codes, the power carrier control lamp string includes:

[0008] A controller, which loads a control signal on the positive pole and / or the negative pole of the power line;

[0009] Several groups of LED sub-strings, each group of LED sub-strings includes several address-coded LEDs; the several groups of LED sub-strings include the address-coded LEDs of M kinds of addresses, and M is greater than or equal to 3;

[0010] The addressable LED includes an LED color lamp group and an LED driving chip for driving the LED color lamp group according to the control signal;

[0011] The several addressable LEDs of each group of LED sub-strings are arranged in a parallel or series connection manner in the order mode of address modulo M;

[0012] The power carrier control lamp string includes N groups of LED sub-strings arranged in the order mode of address modulo M, where N is greater than 2; the several groups of LED sub-strings are connected in parallel or series between the positive pole and the negative pole of the power line.

[0013] It should be understood that the several groups of LED sub-strings include N order modes of address modulo M, and the maximum value of N is the permutation number of M. Both M and N are natural numbers greater than zero. It should be understood that each order mode of address modulo M can have different starting addresses, or different address increment or decrement values.

[0014] It should be understood that the order mode of address modulo M means that when the target address exceeds the M address ranges during the process of address increment or decrement, the remainder value obtained by performing modulo M operation on the target address should be used as the actual target address. For example, in the increasing mode application of 6 addresses (corresponding to including address 0, address 1, address 2, address 3, address 4, address 5), when the current address is 5, the next incremented address is 6 modulo 6, that is, address 0; similarly, in the decreasing mode application of 6 addresses (corresponding to including address 0, address 1, address 2, address 3, address 4, address 5), when the current address is 0, the next decremented address is -1 modulo 6, that is, address 5.

[0015] Preferably, in the order mode of address modulo M, the several addressable LEDs of each group of LED sub-strings are arranged in an increasing or decreasing mode of address modulo M. Through the increasing or decreasing mode, smooth control of the lighting mode is achieved.

[0016] In some applications, the order mode of address modulo M can be in accordance with an increasing rule, or in accordance with a decreasing rule, and the corresponding control is also in accordance with the address increment value or the address decrement value.

[0017] It should be understood that the several groups of LED sub-strings include N order modes of address modulo M, and the order mode of address modulo M can be either an increasing mode or a decreasing mode.

[0018] Preferably, the several addressable LEDs in each group of LED sub-strings are arranged in an increasing or decreasing pattern according to the address modulo M. By setting the same increasing pattern or the same decreasing pattern, on the one hand, the production process of the lamp string is simplified, and the lamp string production process only needs to be carried out according to a single pattern. On the other hand, the lighting control effect is made smoother.

[0019] In some applications, each order pattern according to the address modulo M is set to a specific number, and the several groups of LED sub-strings are arranged regularly according to their respective specific numbers.

[0020] Preferably, the several groups of LED sub-strings are connected in parallel or in series between the positive pole of the power supply line and the negative pole of the power supply line according to a random arrangement of N order patterns according to the address modulo M. It should be understood that the random arrangement means that the arrangement orders of the several groups of LED sub-strings in different product examples are different according to the N order patterns according to the address modulo M.

[0021] Through the random arrangement method, on the one hand, it avoids the heavy tasks caused by the assembly of the several groups of LED sub-strings according to specific rules, simplifies the assembly process of the several groups of LED sub-strings, and makes the finished product assembly simpler and more convenient. On the other hand, it simulates the random effect achieved by the traditional meteor shower through the differences of the control chips themselves, and further obtains the effect of being regular and random in multiple modes through the power line carrier control.

[0022] Preferably, each group of LED sub-strings includes the same number of the addressable LEDs. By including the same number of the addressable LEDs, on the one hand, the current passing through each group of LED sub-strings during operation is balanced, which is suitable for the series use of each group of LED sub-strings. On the other hand, it makes the patterns obtained by controlling each group of LED sub-strings through the power line carrier consistent.

[0023] It should be understood that in some applications, several addressable LEDs with the same address are allowed to be arranged adjacent to each other; in some applications, one addressable LED is arranged at one address, or several addressable LEDs with the same address can also be arranged adjacent to each other; the number of addressable LEDs with the same address arranged adjacent to each other at the same address can be equal or unequal.

[0024] Preferably, the power line carrier control lamp string includes several sets of housings, and the housings are internally provided with snap structures, and each group of LED sub-strings is fixed by the snap structures and then built into the housings. Compared with traditional meteor shower products, there is no need to fix the LEDs on the PCB circuit board, which greatly saves costs. Further, the addressable LEDs work according to the control signals, so that each group of LED sub-strings can achieve multiple working modes, avoiding the deficiency that traditional meteor shower products can only achieve a single mode.

[0025] Preferably, the casing is provided with a positive power plug and a negative power plug. The positive and negative poles of the LED sub-strings are respectively connected to the positive power plug and the negative power plug, and the casing is assembled to the power line carrier control lamp string in a detachable manner.

[0026] Preferably, the casing is provided with a screw socket structure to achieve convenient detachable assembly.

[0027] In the utility model, the controller loads control signals on the positive pole and / or the negative pole of the power line. Several groups of LED sub-strings include M kinds of addresses. Several address LEDs in each group of LED sub-strings are arranged in the order mode of address modulo M, and work according to the control signals, so that the product effect of multiple controllable modes can be achieved through the power line carrier technology with high cost performance; further, several groups of LED sub-strings are connected in parallel or in series to the positive pole and the negative pole of the power line according to N kinds of random arrangement modes of the order mode of address modulo M. On the one hand, it avoids the heavy tasks caused by the assembly of several groups of LED sub-strings according to specific rules. On the other hand, it simulates the random effect of traditional meteor showers, and the regular and random effects in multiple modes can be obtained through power line carrier control.

[0042] In this embodiment, the addressable LEDs in each group of LED sub-strings are arranged in an increasing mode of the address modulo 6, which simplifies the production process of the lamp string and enables the lamp string production process to be carried out only according to a single mode.

[0043] In this embodiment, the 6 groups of LED sub-strings are randomly arranged according to 6 sequential modes of the address modulo 6. In the Figure 1 product example shown in this embodiment, according to the distance from the controller, the arrangements are as follows: arranged in an increasing mode of the address modulo 6 with the starting address of 0 (the first group of LED sub-strings 12), arranged in an increasing mode of the address modulo 6 with the starting address of 4 (the second group of LED sub-strings 13), arranged in an increasing mode of the address modulo 6 with the starting address of 1 (the third group of LED sub-strings 14), arranged in an increasing mode of the address modulo 6 with the starting address of 5 (the fourth group of LED sub-strings 15), arranged in an increasing mode of the address modulo 6 with the starting address of 2 (the fifth group of LED sub-strings 16) and arranged in an increasing mode of the address modulo 6 with the starting address of 3 (the sixth group of LED sub-strings 17).

[0044] It should be understood that in other product cases of this embodiment, the arrangement of each LED sub-string is a random arrangement of 6 increasing modes according to address modulo 6. For example, in other product cases of this embodiment, according to the distance of each LED sub-string from the controller, they can also be respectively: arranged in an increasing mode according to address modulo 6 with a starting address of 4, arranged in an increasing mode according to address modulo 6 with an address of 0, arranged in an increasing mode according to address modulo 6 with a starting address of 5, arranged in an increasing mode according to address modulo 6 with a starting address of 1, arranged in an increasing mode according to address modulo 6 with a starting address of 3, and arranged in an increasing mode according to address modulo 6 with a starting address of 2. In other product cases of this embodiment, it can also be other possible random arrangements of address modes according to address modulo 6.

[0045] In other product cases of this embodiment, the arrangement order of each LED sub-string can be different, and the number of LED sub-strings included can also be different. Obviously, this random arrangement method makes the finished product assembly production process simple and convenient.

[0046] In this embodiment, one address is used to arrange one addressable LED; in other applications, 2 LEDs with the same address, or more LEDs with the same address, can also be arranged.

[0047] In this embodiment, the circuit structure of each addressable LED is the same, as Figure 2 shown, including: a red light-emitting diode 21, a green light-emitting diode 22, a blue light-emitting diode 23, which are the corresponding LED color lamp groups; an LED driving chip 24 that drives the LED color lamp group according to a control signal. The cathodes of the red light-emitting diode 21, the green light-emitting diode 22, and the blue light-emitting diode 23 are connected to the output port of the LED driving chip 24, and the anodes of the red light-emitting diode 21, the green light-emitting diode 22, and the blue light-emitting diode 23 are connected to the anode 25 of the addressable LED of the LED driving chip 24. The cathode of the addressable LED is omitted in Figure 2 the figure.

The LED driving chip 24 is controlled by the state control circuit 244 to count the number of the first group of pulse signals in a frame of control signal as the address information in the control signal; the LED driving chip 24 is controlled by the state control circuit 244 to count the number of the second group of pulse signals in a frame of control signal as the color information in the control signal. The LED driving chip address coding 241 contains 3-bit binary coding and can include up to 8 addresses. In this embodiment, addresses 0, 1, 2, 3, 4, and 5 are used. It should be understood that the 8 address pulses correspond to the 3-bit address 0 in this embodiment.

[0049] The LED driving chip 24 is controlled by the state control circuit 244 to count the number of the first group of pulse signals and the number of the second group of pulse signals in a frame of control signal; when the number of the first group of pulse signals is equal to the LED driving chip address coding 241, the state of the red light emitting diode 21, the green light emitting diode 22, and the blue light emitting diode 23 is determined by the number of the second group of pulse signals. When the number of the first group of pulse signals is equal to the LED driving chip address coding 241, the LED color lamp group driving circuit 243 drives the red light emitting diode 21, the green light emitting diode 22, and the blue light emitting diode 23 according to the counting result of the second group of pulse signals. The LED color lamp group driving circuit 243 in this embodiment includes 3-bit color control bits. It should be understood that when the number of the second group of pulse signals is 8 or 0, the corresponding color control bits are both 0.

[0050] When the number of the first group of pulse signals is equal to the LED driver chip address code 241: when the number of the second group of pulse signals is 1, the red light-emitting diode 21 is on, the green light-emitting diode 22 is off, and the blue light-emitting diode 23 is off; when the number of the second group of pulse signals is 2, the red light-emitting diode 21 is off, the green light-emitting diode 22 is on, and the blue light-emitting diode 23 is off; when the number of the second group of pulse signals is 3, the red light-emitting diode 21 is on, the green light-emitting diode 22 is on, and the blue light-emitting diode 23 is off; when the number of the second group of pulse signals is 4, the red light-emitting diode 21 is off, the green light-emitting diode 22 is off, and the blue light-emitting diode 23 is on; when the number of the second group of pulse signals is 5, the red light-emitting diode 21 is on, the green light-emitting diode 22 is off, and the blue light-emitting diode 23 is on; when the number of the second group of pulse signals is 6, the red light-emitting diode 21 is off, the green light-emitting diode 22 is on, and the blue light-emitting diode 23 is on; when the number of the second group of pulse signals is 7, the red light-emitting diode 21 is on, the green light-emitting diode 22 is on, and the blue light-emitting diode 23 is on; when the number of the second group of pulse signals is 8 or 0, the red light-emitting diode 21 is off, the green light-emitting diode 22 is off, and the blue light-emitting diode 23 is off.

[0051] As Figure 3 shown, in this embodiment, each group of LED sub-strings 3 is fixed by a snap structure and then built into the housing 31. The built-in snap structure 311 of the housing is as Figure 2 shown. By the built-in snap structure, the LED sub-strings are fixed. Compared with traditional meteor shower products, there is no need to fix the LEDs on the PCB circuit board, which greatly saves costs.

[0052] As Figure 4 shown, a frame of control signal 4 includes a first group of pulse signals 41 and a second group of pulse signals 42. The low-level 43 time of the first group of pulses and the second group of pulse signals is 20 us, the high-pulse width time 44 is 20 us, and the interval time 45 between the first group of pulse signals and the second group of pulse signals is 100 us.

[0053] In this example, the controller 11 loads the control signal at the negative pole, so that the LED 10 120, LED 11 121, LED 12 122, LED 13 123, LED 14 124, LED 15 125, LED 24 130, LED 25 131, LED 20 132, LED 21 133, LED 22 134, LED 23135.

[0057] Obviously, various color random flowing water effects can be achieved through other control methods; various mode effects such as trailing flowing water can also be further achieved.

[0058] The utility model loads control signals on the positive pole and / or the negative pole of the power line through a controller. Several groups of LED sub-strings include M kinds of addresses. Several addressable LEDs in each group of LED sub-strings are arranged in the order mode of address modulo M and work according to the control signals. Further, they are connected in a random arrangement manner of each LED sub-string, and the random product effects of multiple controllable modes are realized through the power line carrier technology with high cost performance, achieving the application effects with regularity and randomness at the same time.
