(12) Referring to FIG. 1, the present disclosure provides an LED drive system 900 including a drive power supply 21, and an LED controller 100 installed with an LED lamp 200 in a plug-in manner. When the LED controller 100 is plugged in, the LED controller 100 can obtain a power from the LED lamp 200 to start working. A control of the drive power supply 21 includes outputting a driving signal with a driving mode and a driving intensity to control a lighting mode and a lighting intensity of the LED lamp 200.

(13) The driving mode includes: a high level continuous, a low level continuous, a high level and a low level alternative with each other, and controlling a switching time interval between high and low levels, such controls of the driving signals enable the lighting mode of the LED lamp 200 to be controlled, resulting in the LED lamp 200 presenting: lighting, extinguishing, a timed shutdown, turning off first and then turning on, turning on for three minutes and turning off for one minute and then turning on again, etc. The driving intensity is achieved through controlling the adjustment signal synchronously output by the driving signal. For example, when the adjustment signal is a PWM signal, a duty cycle of the PWM signal is adjusted to control a current of the PWM signal, thereby using the current to adjust the lighting intensity of the LED lamp 200. An adjustment of the driving intensity refers to control a working power of the LED lamp 200 when the LED lamp 200 is lit up, such as a full power, a power of 15%, and a power of 80%, etc. The power corresponds to an illumination intensity of the LED lamp 200.

(14) The LED controller 100 includes a detection control module 11, a switching adjustment module 12, a detection calculation module 13 and the drive power supply 21.

(15) There is a plurality of detection control modules 11, such as a PIR signal module configured to detect infrared signals, and a DALI signal module configured to receive DALI signals. That is to say, two or more detection control modules 11 are different from each other, which include different functions, different signal acquisition, and different signal output and signal generation. Different detection control modules 11 correspond to different detection directions or control data sources. That is, the detection control module 11 is configured to generate or receive detection control signals and then output the detection control signals, and the plurality of detection control modules 11 output different detection control signals.

(16) In an embodiment of the present disclosure, the detection calculation module 13 is connected to both the switching adjustment module 12 and the detection control module 11 in a conductive manner, and configured to select the detection control signal A10 to be received under an adjustment trigger of the switching adjustment module 12, and then convert the detection control signal A10 into an adjustment signal A20 to output to the drive power supply 21.

(17) Referring to FIG. 2, one of the simplest ways is that the switching adjustment module 12 is an adjusting switch 121 with a plurality of different gears (A-E) that can emit different triggering signals, such as different voltages (1.7V, 1.3V, 0.9V, 0.5V, 0.1V). When the detection calculation module 13 receives a trigger voltage value output from the switching adjustment module 12, it can select a corresponding detection control signal A10 that is sent from the plurality of detection control modules 11 which is connected to the detection calculation module 13 by identifying the voltage value. Based on the detection control signal A10, the adjustment signal A20 is generated to drive and control the drive power supply 21, which achieves compatibility of the plurality of detection control modules 11 by the detection calculation module 13.

(18) Specifically, the switching adjustment module 12 is configured to adjust and trigger the detection calculation module 13, so that the detection calculation module 13 can select one of the plurality of detection control signals A10 to process and convert into the corresponding adjustment signal A20.

(19) The switching adjustment module 12 is configured to adjust an own resistance value thereof by the above way, to output voltages with different sizes, the adjustment way can be achieved by the adjusting gears (A-E).

(20) Specifically, the switching adjustment module 12 includes a plurality of adjusting branches 122 connected in parallel to each other, a control output terminal (Fb2) is formed at an end of a parallel connection point X thereof and configured to output the voltages with different sizes (1.7V, 1.3V, 0.9V, 0.5V, 0.1V) to the detection operation module 13. The number of adjusting branches 122 is the same as that of detection control modules 11, and each adjusting branch 122 corresponds to one detection control module 11.

(21) The adjusting branch 122 includes a conductive switch 123 and an adjusting resistor (R63A-R63E) connected in series to the conductive switch 123, a plurality of conductive switches 123 are combined to form an adjusting switch 121, wherein the adjusting resistors (R63A-R63E) of the plurality of adjusting branches 122 have different values from each other, wherein when the conductive switch 123 is turned off and the corresponding adjusting branch 122 is turned on, and the adjusting branch 122 that is turned on outputs a corresponding voltage (1.7V, 1.3V, 0.9V, 0.5V, 0.1V) to the detection calculation module 13.

(22) Referring to FIG. 1, in the present disclosure, when the detection control signals A10 input by the detection calculation module 13 come from different detection control modules 11, the adjustment signals A20 output from the detection calculation module 13 have the same output formats and/or the same output terminals to achieve compatible data output thereof.

(23) In the present disclosure, the adjustment signals A20 are all output through PWM modulation signals, the PWM modulation signals can modulate and control the driving intensity and/or the driving mode of the drive power supply 21, thereby indirectly controlling the illumination intensity and/or the lighting mode of the LED lamp 200.
