[0030] Referring to Figures 1 to 6 An LED lamp, as shown in the figure, comprises a main body 1 and an LED driving device, the LED driving device is arranged in the main body 1;A LED lamp panel 30 is arranged on the main body 1, and a plurality of LED lamp beads 20 are arranged on the LED lamp panel 30;The LED driving device comprises a dimming driving power supply 110, an adjusting module 120 and an output control module 130;The LED lamp panel 30 is electrically connected with the dimming driving power supply 110;The adjusting module 120 has a plurality of adjusting gears, and each adjusting gear corresponds to a driving mode;The output control module 130 is electrically connected with the dimming driving power supply 110 and the adjusting module 120 respectively.
[0031] The dimming driving power supply 110 is configured to output a constant voltage Vdd and at least two driving signals Vx according to the driving mode;The adjusting module 120 has at least two adjusting gears, and each adjusting gear corresponds to a driving mode, and the adjusting module 120 sends an adjusting trigger signal a after being dialled to the adjusting gear;The control output module 130 is configured to be able to output a plurality of adjusting signals b corresponding to the adjusting trigger signal a according to a plurality of adjusting trigger signals a, and the control output module 130 sends the corresponding adjusting signal b to the dimming driving power supply 110 according to the adjusting trigger signal a;The LED lamp panel 30 is electrically connected with the dimming driving power supply 110.
[0032] The dimming driving power supply 110 switches its driving mode according to the adjustment signal b, and outputs a driving signal Vx corresponding to the driving mode to the LED lamp panel, so that the LED lamp panel works in the corresponding driving mode.
[0033] The LED driving device can adjust the LED lamp beads 20 to different adjustment gears through the adjustment module 120 according to the required driving mode, and send an adjustment trigger signal a; after the adjustment trigger signal a is sent to the control output module 130, the control output module 130 detects the adjustment trigger signal a and judges the driving mode corresponding to the adjustment trigger signal a, and outputs an adjustment signal b to the dimming driving power supply 110 according to the pre-set control strategy, so that the dimming driving power supply 110 drives the LED lamp beads 20 to light according to the pre-set driving mode, thereby realizing the compatibility of multiple different dimming driving modes.

The dimming driving power supply starts to work and drives the LED lamp panel, at this time the LED lamp panel can start to work according to the 0-10V dimming driving mode; similarly, when the LED lamp panel needs to be connected or set according to other driving modules, such as DALI driving mode, at this time before the LED lamp panel is lit, only the adjustment module needs to be adjusted to the adjustment gear corresponding to the DALI driving mode; the driving device is convenient to operate and can adapt to various driving modes.
[0035] The adjustment module 120 includes an adjustment switch 121 and a first detection following circuit 122. The adjustment switch 120 includes at least two adjustment gears, each adjustment gear is used to turn on a connection of different lines, so that the adjustment switch 120 outputs different adjustment voltages a1; the first detection following circuit 122 is electrically connected between the adjustment switch 120 and the control output module 130, and is used to impedance isolation and filter the adjustment voltage a1, thereby outputting the adjustment trigger signal a.

[0037] After the adjustment switch 121 is manually adjusted, the output adjustment voltage a1 is output, and the size of the adjustment voltage a1 corresponds to different driving modes; the first detection follow-up circuit 122 processes the adjustment voltage a1, mainly including impedance isolation and filtering, to output the stable adjustment trigger signal a that can be detected; the logic chip 131 receives the adjustment trigger signal a, detects the adjustment trigger signal a, and according to the size of the trigger signal a, sends the corresponding intermediate signal b1 according to the control strategy preset in the internal, and the size or the information carried by the same intermediate signal b1 corresponds to the driving mode, and the intermediate signals b1 with different sizes or carrying different information correspond to different driving modes; then the control peripheral circuit 132 processes the intermediate signal b1, and the main processing process includes impedance matching voltage follow-up and electrical isolation, and then the control peripheral circuit 132 outputs the adjustment signal b corresponding to the intermediate signal b1 to the dimming driving power supply 110; the dimming driving power supply 110 outputs the driving voltage and / or the control voltage Vx to the LED lamp bead 20 according to the adjustment signal and the control strategy stored in the internal according to the corresponding driving mode, so as to realize the purpose that the LED lamp bead 20 works according to the corresponding driving mode.
[0038] The adjustment voltage a1 output by the adjustment switch is a continuous level signal, different adjustment voltages have different level amplitudes, for example, 5V or 4V continuous level; similarly, the first detection follow-up circuit outputs the adjustment trigger signal a as a level signal because it receives a level signal; and after the logic chip receives the adjustment trigger signal, the adjustment trigger signal is detected, and the intermediate signal b1 output according to the preset control strategy can be a level signal, of course, according to the requirements of the dimming driving power supply to be controlled, it can also be: a control signal with a rising edge or a falling edge, a high-low level signal with a specific switching time, a square wave signal, a triangular wave signal and other control signals with their own special marks, carrying control information, which can be uniquely identified, and these control signals can be identified by the dimming driving power supply; and the control peripheral circuit outputs the corresponding signal, i.e. the adjustment signal b, which is more stable, not attenuated and easy to be identified, according to the characteristics of the received intermediate signal b1.
[0039] The adjustment switch 121 has three adjustment gears, which are first gear S1, second gear S2 and third gear S3. When the adjustment switch 121 is adjusted to different adjustment gears S, different adjustment voltages b are outputted, and different adjustment voltages b will also output different corresponding adjustment trigger signals a after passing through the first detection and following module 121.
[0040] The adjustment driving power supply 110 sets three driving modes, which are: Digital Addressable Lighting Interface (DALI) addressable lighting dimming mode; Digital Multiple X RDM (DMX-RDM) dimming mode; 0-10V linear dimming mode.

[0042] The dimming driving power supply 110 outputs different driving signals Vx when working in different driving modes, and can also receive signal inputs from different external devices according to its own driving mode, such as sensor, other control switch, infrared controller and other external devices, so as to realize dimming control under the current driving mode with the cooperation of external devices.
[0043] The control strategy of the logic chip 131 includes detecting the voltage value V of the adjustment trigger signal a, comparing the voltage value V of the adjustment trigger signal a with at least two preset threshold voltages (V01, V02, V01≤V02), and outputting the intermediate signal b with different sizes according to the comparison result (corresponding to voltage values V11, V12, V13). As stated above, the intermediate signal here can be a continuous level signal, a rising or falling edge signal, a high or low level signal with a specific switching time, a square wave signal, a triangular wave signal and other signals with unique special marks that can be uniquely identified. These signals can be recognized by the dimming driving power supply.

[0047] The voltage value V of the adjustment trigger signal a corresponds to the different resistance on the line turned on by the adjustment switch 121. Specifically, the adjustment switch SW1 includes a first pin 1, a second pin 2 and a third pin 3;
[0048] The first detection follower circuit 122 includes a first resistor R9, a second resistor R4, a third resistor R8, a first capacitor C5 and a first operational amplifier U3. One end of the first resistor R9 is connected with the first pin 1, and the other end of the first resistor R9 is grounded GND; one end of the second resistor R4 is connected with the third pin 3, and the other end of the second resistor R4 is grounded GND; one end of the third resistor R8 is connected with the second pin 2, and the other end of the third resistor R8 is connected to the constant voltage source 5V; one end of the first capacitor C5 is connected with the second pin 2, and the other end of the first capacitor C5 is grounded GND; the positive input end 5 of the first operational amplifier U3 is electrically connected with the second pin 2, the negative input end 4 of the first operational amplifier U3 is grounded through the fourth resistor R6, and is connected to the output end 2 of the first operational amplifier U3 through the fifth resistor R5. The output end 2 of the first operational amplifier U3 outputs the adjustment trigger signal a to the logic chip U2.
[0049] When the first gear S1, the voltage value V of the adjustment trigger signal a=constant voltage Vcc*first resistor resistance R9 / (first resistor resistance R9+third resistor resistance R8); when the second gear S2, the voltage value V of the adjustment trigger signal a=constant voltage Vcc*second resistor resistance R4 / (second resistor resistance R4+third resistor resistance R8); when the third gear S3, the voltage value V of the adjustment trigger signal a=constant voltage Vcc=5V.

[0051] When the adjusting switch SW1 is adjusted to the second gear S2, the second pin 2 and the third pin 3 are conducted, the first pin 1 and the third pin 3 are disconnected, at this time, the voltage on the second pin 2, i.e. the adjusting voltage b1, is the voltage value after the voltage on the second pin 2 is divided by the third resistor R8 and the second resistor R4, if the third resistor is 10Ω and the second resistor R4 is 5Ω, the adjusting voltage b1 is 0.33V;
[0052] When the adjusting switch SW1 is adjusted to the third gear S3, the first pin 1, the second pin 2 and the third pin 3 are all disconnected, at this time, the voltage on the second pin 2, i.e. the adjusting voltage b1, is the constant voltage source voltage 5V.
[0053] By selecting the first resistor R9, the second resistor R4 and the third resistor R8 with different resistance values, the purpose of outputting different adjusting voltages by the adjusting switch SW1 at different adjusting gears S can be achieved, and the structure is simple and easy to realize.
[0054] The first capacitor C5 is used for filtering and absorbing the voltage glitch and surge voltage generated when the adjusting switch SW1 switches the adjusting gear S, preventing damage to the first operational amplifier U3; and discharging at the moment when the first operational amplifier U3 is powered off, reducing the possibility of large voltage pulses output to the logic chip U2, for protecting the logic chip U2.
[0055] The first operational amplifier U3 is used as a voltage follower, and the size of the output voltage value is exactly the same as the adjusting voltage b1, which can also serve the purpose of impedance matching, isolating the logic chip U2 and the adjusting switch SW1, and protecting the logic chip U2.
[0056] The logic chip U2 is a single-chip microcomputer, including a detection input end 4 and a driving output end 3; the detection input end 4 is connected with the output end 2 of the first operational amplifier U3 to receive the adjusting trigger signal b; the driving output end 3 is used for outputting the intermediate signal a1.

[0060] The MOS tube Q1 has extremely high impedance from the source S to the gate G and can prevent the influence of the voltage on the side of the dimming driving power supply 110 on the logic chip U2, so when the adjustment switch SW1 is invalid, or the logic chip U2 is damaged, or it is required to artificially control the dimming driving power supply 110 without the intermediate signal b1 output by the logic chip U2, the voltage value on the source S of the output end of the MOS tube Q1 can also be adjusted through the control terminal 40, so that the purpose of controlling the dimming driving power supply 110 is achieved, and the voltage output by the control terminal 40 to the source of the MOS tube Q1 does not cause any influence on the logic chip U2.
