[0073] Figure 1 A schematic diagram of the structure of a flame lamp control device provided by an embodiment of the present invention is shown in FIG. Figure 1 As shown, a flame lamp control device 100 provided in this embodiment includes a light emitting array 110 , a single chip control circuit 120 and a current control circuit 130 .
[0074] The light emitting array 110 is connected to the current control circuit 130 and the single chip control circuit 120 respectively.
[0075] The current control circuit 130 is used to provide a controllable current to the light emitting array 110 .
[0076] The single chip control circuit 120 is used to control the light emitting array 110 to emit light in the shape of flames.
[0077] In this embodiment, the light-emitting array uses LED (Light-Emitting Diode) lamps, which are called the fourth generation lighting sources or green light sources, and have the characteristics of energy saving, environmental protection, long life, and small size.
[0078] In this embodiment, the current control circuit provides controllable current to the light-emitting array. When light emission is required, the single-chip control circuit controls the LED lamps in the light-emitting array to emit flame-shaped light. Since the life of LED lamps is long, the service life of the flame lamps can be increased.
[0079] The flame lamp control device may further include a control switch connected to the single-chip control circuit, for receiving an on command or off command output by a user, and sending the on command to the single-chip control circuit. When the single-chip control circuit receives the on command, that is, when light emission is required, the LED lamps in the light-emitting array are controlled to emit light in the shape of a flame.
[0080] In this embodiment, the flame lamp control device includes a light-emitting array, a single-chip control circuit and a current control circuit. The light-emitting array is connected to the current control circuit and the single-chip control circuit respectively. The current control circuit provides controllable current for the light-emitting array. The single-chip control circuit controls the light-emitting array to emit light in a flame shape. It is possible to control the light-emitting array to emit light in a flame shape. By using the light-emitting array to emit light, there is no need to use a quartz lamp with a short service life, thereby increasing the service life of the flame lamp. There is no need to use a fan, and the noise is low.
[0081] Figure 2 A schematic diagram of the structure of a flame lamp control device provided by another embodiment of the present invention is shown in FIG. Figure 2 As shown, the light array 110 is composed of N*M light emitting units 111, where N is the number of rows of the light array 110, and M is the number of columns of the light array 110. N and M are integers greater than or equal to 1, respectively.
[0082] The first port of each light emitting unit 111 is connected to the output end of the current control circuit 130 .
[0083] The second ports of the light emitting units 111 corresponding to each row in the light emitting array 110 are connected to a signal output interface corresponding to the row on the single chip control circuit 120, and the single chip control circuit 120 controls the light emitting units 111 corresponding to the row to present the same flame element.
[0084] The second ports of the light-emitting units 111 corresponding to each column in the light-emitting array 110 are respectively connected to the signal output interface corresponding to the row where each light-emitting unit 111 is located on the single-chip control circuit 120. The single-chip control circuit 120 controls each light-emitting unit 111 on the column to arrange according to the distribution rules of the flame elements to present different flame elements.
[0085] like Figure 2 As shown, the current control circuit 130 includes a plurality of current control units 131 .
[0086] Each current control unit 131 is connected to a light emitting unit 111 and is used to provide a controllable current to the light emitting unit 111 .
[0087] In this embodiment, each current control unit is connected to a light-emitting unit to provide a controllable current for the light-emitting unit. The controllable current can be a maximum limiting current or a constant current.
[0088] In this embodiment, the light array is composed of N*M light emitting units, the number of rows of the array is N, the number of columns is M, and N and M are integers greater than or equal to 1. The lights emitted by all the light emitting units corresponding to each column in the light array can form a complete flame.
[0089] The flame is composed of multiple flame elements, each of which corresponds to a part of the flame. For example, the flame element can be the color and shape of the flame root, the color and shape of the flame middle, the color and shape of the flame tip, etc.
[0090] In this embodiment, the light-emitting units in the light-emitting array correspond to a flame element, and the light-emitting units in each row can present the same flame element. The single-chip control circuit controls the light-emitting units corresponding to each row to present the flame element corresponding to the row. For example, the single-chip control circuit controls the light-emitting units corresponding to the first row to present the flame element corresponding to the first row, that is, the light-emitting units corresponding to the first row are controlled to emit light of the color of the flame element corresponding to the first row, and the shape of the light is the shape of the flame element corresponding to the first row.
[0091] Among them, the light-emitting units corresponding to each row are connected to the same signal output interface on the single-chip control circuit, which can realize unified control of the light-emitting units corresponding to the row and improve the control efficiency of the light-emitting units.
[0092] In this embodiment, the light-emitting units in each column of the light-emitting array correspond to different flame elements, and the single-chip control circuit controls the light-emitting units in each column to be arranged according to the distribution rules of the flame elements to present the corresponding flame elements. For example, each column is composed of 3 light-emitting units, and the single-chip control circuit controls the light-emitting units in each column to present the corresponding flame elements according to the distribution rules of the flame elements (that is, the arrangement order, shape and color of the flame elements in the flame), that is, the first light-emitting unit in each column is controlled to present the color and shape of the tip of the flame, the second light-emitting unit is controlled to present the color and shape of the middle of the flame, and the third light-emitting unit is controlled to present the color and shape of the root of the flame, so as to realize the control of each column of light-emitting units to emit light in the shape of flames.
[0093] The light-emitting units corresponding to each column are connected to the signal output interface corresponding to the row where the light-emitting units are located, that is, the light-emitting units in each column are connected to different signal output interfaces.
[0094] In this embodiment, the light-emitting units corresponding to each row are connected to the same signal output interface of the single-chip microcomputer control circuit, so that the single-chip microcomputer control circuit can simultaneously control the light-emitting units corresponding to a row to emit light, and the light-emitting units corresponding to each column are connected to the signal output interface corresponding to the row where they are located. The single-chip microcomputer can control the light-emitting units corresponding to all columns to emit light in the shape of flames through a set of control signals. The flame shape is more realistic, the circuit principle is simple, and the generation process is simplified.
[0095] Figure 3 A circuit diagram of a light emitting unit provided in one embodiment of the present invention is shown in FIG. Figure 3 As shown, the light emitting unit 111 includes a preset number of LED light strings, and the signal output interface includes a preset number of signal output terminals.
[0096] The cathodes of a preset number of LED light strings are connected to the signal output ends of a preset number in a one-to-one correspondence, and the anodes of a preset number of LED light strings are connected in parallel to the output end of the current control circuit.
[0097] Each LED light string is composed of one or more LED lights connected in series.
[0098] In one possible design, the preset number is 3 or 1.
[0099] In one possible design, N is 6 and M is 3.
[0100] In this embodiment, the light-emitting unit is composed of a preset number of LED light strings, and the signal output interface also includes a preset number of signal output terminals. Each LED light string in the light-emitting unit is connected to a signal output terminal in the signal output interface corresponding to the row in which it is located in a one-to-one correspondence. That is, the anode of each LED light string in the light-emitting unit is connected to the output terminal of the current control circuit, and the cathode of the preset number of LED light strings in the light-emitting unit is connected to a preset number of signal output terminals in a one-to-one correspondence. For example, the light-emitting unit includes 3 LED light strings, and the cathode of the first LED light string in the light-emitting unit is connected to the first signal output terminal in the corresponding signal output interface, the cathode of the second LED light string is connected to the second signal output terminal in the corresponding signal output interface, and the cathode of the third LED light string is connected to the third signal output terminal in the corresponding signal output interface.
[0101] Each LED light string is composed of one LED light or multiple LED lights connected in series.
[0102] Exemplarily, there are 3 light-emitting units in the first row, and the anode of each LED light string in the first light-emitting unit, the anode of each LED light string in the second light-emitting unit, and the anode of each LED light string in the third light-emitting unit are all connected to the output end of the current control circuit, the cathode of the first LED light string in the first light-emitting unit, the cathode of the first LED light string in the second light-emitting unit, and the cathode of the first LED light string in the third light-emitting unit are all connected to the first signal output end of the signal output interface corresponding to the first row, and the cathode of the second LED light string in the first light-emitting unit, the cathode of the second LED light string in the second light-emitting unit, and the cathode of the second LED light string in the third light-emitting unit are all connected to the second signal output end of the signal output interface corresponding to the first row.
[0103] Among them, Figure 4 As shown, the number of rows of the light-emitting array may be 6, the number of columns may be 3, each light-emitting unit may include 3 or 1 LED light strings, and each LED light string may include one LED lamp.
[0104] Through research, relevant personnel found that the shape of the flame tip is relatively sharp, so not too many LED lights are needed. The light-emitting unit that presents the flame tip in the light-emitting array can be made to include one LED light string, and the light-emitting units that present the remaining flame elements in the light-emitting array can be set to include three LED light strings, thereby reducing production costs while ensuring the flame simulation effect.
[0105] Figure 5 A circuit diagram of a current control unit provided in an embodiment of the present invention is shown in FIG. Figure 5 As shown, the current control unit 131 includes: a first resistor R1, a transistor Q1, a second resistor R2 and a voltage stabilizing diode D1.
[0106] One end of the first resistor R1 receives a power supply signal, and the other end is connected to the emitter of the transistor Q1 .
[0107] The collector of the transistor Q1 is connected to the first port of the light emitting unit, and the base is connected to one end of the second resistor R2.
[0108] The other end of the second resistor R2 is grounded.
[0109] The anode of the voltage stabilizing diode D1 is connected to the base of the transistor Q1 , and the cathode receives a power supply signal.
[0110] In a possible design, the single-chip microcomputer control circuit 120 includes a serial-to-parallel conversion unit 121 and a single-chip microcomputer U1.
[0111] The serial-to-parallel conversion unit 121 is connected to the single-chip microcomputer U1 and the light-emitting array 110 respectively.
[0112] The single chip microcomputer U1 is used for outputting serial light control signals to the serial-to-parallel conversion unit 121 .
[0113] The serial-to-parallel conversion unit 121 is used to convert the serial light control signal into a parallel light control signal and output the parallel light control signal to the light array 110 .
[0114] In this embodiment, when flame-shaped light is required, the single-chip microcomputer needs to control all LED lights in the light-emitting array to turn on or off at the same time. Therefore, the single-chip microcomputer needs to first output a serial light control signal to the serial-to-parallel conversion unit. The serial-to-parallel conversion unit converts the serial light control signal into a parallel light control signal, thereby realizing the simultaneous control of the light on and off of all LED lights.
[0115] Figure 6 A circuit schematic diagram of a single chip control circuit provided by an embodiment of the present invention is shown in FIG. Figure 6 As shown, the serial-to-parallel conversion unit 121 includes a first shift register U2 and a second shift register U3.
[0116] The first shift register U2 and the second shift register U3 are respectively connected to the single chip computer U1.
[0117] The first shift register U2 and the second shift register U3 are connected.
[0118] In this embodiment, the serial-to-parallel conversion unit includes a first shift register and a second shift register, and the LED light string in the light-emitting array is connected to the signal output end of the first shift register or the second shift register. Figure 6 As shown, the Q0 to Q7 pins of the first shift register U2 and the second shift register U3 are connected to the LED light strings in the light-emitting unit respectively.

Since the number of signal output ends of the first shift register is limited, it is necessary to increase the shift register. Therefore, the second LED light strings in the first light-emitting unit, the second light-emitting unit and the third light-emitting unit corresponding to the fourth row are respectively connected to the Q0 pin in the second shift register.
[0119] The Q0 to Q7 pins of the first shift register U2 and the second shift register U3 are signal output ends, respectively, which are connected to the LED light strings in the corresponding light-emitting units.
[0120] The VCC pins of the first shift register U2 and the second shift register U3 and The pins are respectively connected to receive power signals, the GND pins are respectively grounded, the OE pins are respectively connected to the OE pins of the microcontroller, the STCP pins are respectively connected to the STCP pins of the microcontroller, and the SHCP pins are respectively connected to the CLK pins of the microcontroller.
[0121] The DS pin of the second shift register U3 is connected to the DS pin of the single chip microcomputer, and the DS pin of the first shift register U2 is connected to the Q7S pin of the second shift register U3.
[0122] The VDD pin of the microcontroller receives the power signal, and the GND pin is grounded.

[0125] The positive electrode of the second capacitor C2 receives the power signal, and the negative electrode is grounded.
[0126] The positive electrode of the third capacitor C3 receives the power signal, and the negative electrode is grounded.
[0127] In this embodiment, when the number of light-emitting units in the light-emitting array is large, the number of shift registers can be increased to enable the single-chip microcomputer to simultaneously control the on and off of the LED lights of the light-emitting units in the light-emitting array.
[0128] In this embodiment, the single-chip microcomputer control circuit includes a shift register and a single-chip microcomputer. The single-chip microcomputer is connected to the shift register, and the shift register is connected to the light-emitting array. The single-chip microcomputer controls the LED lights to turn on and off simultaneously through the shift register so that the light-emitting array emits flame-shaped light. Fewer devices are required and the connection relationship is simple. Under the premise of ensuring the realistic flame shape, the required cost is reduced and the process is simplified.
