Detailed Description
The present invention will be described in detail below with reference to the embodiments shown in the drawings. The embodiments are not intended to limit the invention, but structural, methodological, or functional modifications of the invention from those skilled in the art are included within the scope of the invention.
Referring to fig. 1-4, the present application provides an LED strip intelligent driver 100, comprising: an output interface 1, an LED driving circuit 2 and an MCU3.
Referring to fig. 1, the output interface 1 includes a first power output 11 and a second power output 12. The first power output 11 and the second power output 12 may be connected to the power output lines individually or simultaneously to match the different power LED strips.
It should be appreciated that the maximum power of a typical lamp strip is 150W, which corresponds to a current of 6.25A. The maximum driving power of the LED strip intelligent driver 100 is designed to be 150W so that the LED strip can be driven. If the output interface 1 has only one power output, only one power output line of maximum power can be connected. When the power of the actually used LED lamp strip is smaller, the current flowing through the power output line is smaller, and the power output line with the power of 150W is too thick. Therefore, the output interface 1 of the LED strip intelligent driver 100 provided in the present application includes two power strip output terminals, namely, the first power output terminal 11 and the second power output terminal 12.
Referring to fig. 2 to 3, when the power of the actually used LED light strip is 70W or less, one wire power output line is connected to the first power output terminal 11. When the power of the actually used LED light strip is 70W to 150W, two wire power supply output lines are connected to the first power output terminal 11 and the second power output terminal 12, respectively. The power output line has a line diameter of AWG18, which can bear 3.2A and a corresponding power of 76.8W. Therefore, the intelligent driver of the LED lamp strip can drive the LED lamp strip with various powers, and the shared design is realized.
And the LED driving circuit 2 is connected with the output interface 1 and the MCU3 and is used for driving the LED lamp strip according to the control of the MCU3.
And the MCU3 is connected with the LED driving circuit 2 and is used for controlling the driving power of the LED driving circuit 2 based on the power of the LED lamp strip.
Specifically, the MCU3 obtains the power of the LED light strip, and if the power of the LED light strip is less than or equal to the first set power, controls the driving power of the LED driving circuit 2 to be less than or equal to the first set power. The first set power may be 70W. And if the power of the LED lamp strip is larger than the first set power, controlling the driving power of the LED driving circuit to be smaller than or equal to the second set power, wherein the second set power is larger than the first set power. The second set power may be 150W.
Specifically, the MCU3 is further connected to a current detection circuit 4, the current detection circuit 4 is configured to detect a current of the LED strip and feed back the current to the MCU3, and the MCU3 determines a power of the LED strip according to the current and controls a driving power of the LED driving circuit 2.
Referring to fig. 4, the output interface 2 further includes a plurality of pulse signal output terminals 13, and when the LED strip is a dual color temperature strip, the pulse signal output terminals 13 include a cool color output port 131 and a warm color output port 132. When the LED strip is a dual color temperature strip plus an RGB strip, the pulse signal output terminal 13 includes a cool color output port 131, a warm color output port 132, an R output port 133, a G output port 134, and a B output port 135. Each pulse signal output end is connected with a load wire to the LED lamp strip.
Specifically, each pulse signal output end 13 corresponds to an LED strip of one color. The pulse signal may be a PWM pulse control signal, which controls the brightness of the corresponding LED strip to be maximum when the PWM pulse control signal is at a low level, and controls the brightness of the corresponding LED strip to be minimum when the PWM pulse control signal is at a high level. Therefore, the brightness of the LED lamp strips with different colors can be independently controlled.
Specifically, the LED strip intelligent driver 100 further includes a wireless module 5, where the wireless module 5 is configured to wirelessly communicate with the outside. The radio module 5 comprises in particular a LORA chip and an antenna connected thereto.
Specifically, the LED strip intelligent driver 100 further includes a power module 6, where the power module 6 is connected to an external power source. The external power supply can be 24V, and the power of the external power supply is larger than or equal to the power of the LED lamp strip.
