Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to the field of electric lighting source circuit technology. Background Technology

[0002] In existing technologies, breathing lights generally use a single LED bead to control the voltage applied to continuously change the light intensity of the bead to achieve the breathing effect. For the need for multi-color display, three LED beads are installed side by side at one point, but in essence, it is still about controlling a single LED bead.

[0003] In practice, the lifespan of LED beads varies, and their light intensity is generally significantly weaker. This leads to the LED beads being easily damaged in many breathing light products, seriously affecting the user experience and user reputation. Utility Model Content

[0004] The purpose of this invention is to provide a smart control array breathing light circuit, which enables multi-color breathing lights to be realized through array LED beads, greatly improving the overall durability and light intensity of breathing light products, thereby effectively improving the user experience and user reputation of breathing light products.

[0005] To solve the above-mentioned technical problems, this utility model provides an intelligent control array breathing light circuit, including a main control chip. The main control chip is connected to control the array LED beads through matrix control. A battery protection chip is connected to multiple batteries and supplies power to the main control chip and the array LED beads. A protection circuit is connected to the positive terminal of the battery protection chip, and the main control chip is connected to the control protection circuit. The battery protection chip outputs a PMOS transistor through the PCDR terminal to the positive terminal of the battery and an NMOS transistor through the NDDR terminal to the negative terminal of the battery.

[0006] The NDDR terminal of the battery protection chip is connected to multiple parallel N-channel enhancement-mode MOSFETs.

[0007] The N-channel enhancement-mode MOSFET is a CS100N03A4.

[0008] The PMOS transistor used is a KS4435HB.

[0009] The positive terminal of the array LED is connected to a transistor, the main control chip is connected to a control transistor, and the negative terminal of the array LED is directly connected to the GPIO port of the main control chip.

[0010] The array LED beads are controlled by a transistor connected to one GPIO port of each pair of main control chips at the positive end.

[0011] The battery protection chip is PT6305, and the main control chip is CS88F313BEO.

[0012] The NCDR port of the battery protection chip is connected to the main control chip.

[0013] The protection circuit has a three-terminal integrated voltage regulator connected inside, and outputs a 5V voltage through the three-terminal integrated voltage regulator. This 5V voltage is connected to the positive terminal of the array lamp beads, and the branch connected in parallel to the three-terminal integrated voltage regulator is connected to the voltage detection terminal of the main control chip.

[0014] In the protection circuit, a PNP transistor is connected to the link connecting the positive terminal to the voltage output. The collector of the PNP transistor is connected to the positive terminal and the ADC pin of the main control chip, respectively. Voltage divider resistors are connected in series on the links connecting the positive terminal and the ADC pin of the main control chip to the collector of the PNP transistor.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments. The division of the following embodiments is for ease of description and should not constitute any limitation on the specific implementation of this utility model. The various embodiments can be combined with and referenced by each other without contradiction.

[0024] The first embodiment of this utility model relates to an intelligent control array breathing light circuit, including a main control chip. The main control chip is connected to control array LED beads through matrix control. A battery protection chip is connected to multiple batteries and supplies power to the main control chip and array LED beads. A protection circuit is connected to the positive terminal of the battery protection chip, and the main control chip is connected to the control protection circuit. The battery protection chip outputs and controls a PMOS transistor through the PCDR terminal to the positive terminal of the battery, and outputs and controls an NMOS transistor through the NDDR terminal to the negative terminal of the battery.

[0025] Therefore, on the one hand, by connecting and controlling the array of LED beads, and based on the control of the main control chip, a colorful breathing light can be effectively achieved through the array of LED beads. On the other hand, the battery protection chip combines two typical connection methods, charging PMOS and charging NMOS, to ensure the stability of charging and daily use, and to ensure that the breathing light product based on this application has extremely high overall durability, thereby greatly improving the user experience of the product.

[0026] The second embodiment of this utility model is largely the same as the first embodiment, mainly in the further optimization of selection details, where the NDDR terminal of the battery protection chip is connected to multiple parallel N-channel enhancement-mode MOS transistors.

[0027] Preferably, the N-channel enhancement-type MOSFET is CS100N03A4.

[0028] Preferably, the PMOS transistor is a KS4435HB.

[0029] Preferably, the battery protection chip is PT6305 and the main control chip is CS88F313BEO.

[0030] The third embodiment of this utility model is largely the same as the first embodiment, mainly in the further optimization of the array lamp bead connection control. The positive terminal of the array lamp bead is connected to a transistor, the main control chip is connected to a control transistor, and the negative terminal of the array lamp bead is directly connected to the GPIO port of the main control chip.

[0031] Furthermore, for each pair of LEDs in the array, one GPIO port of the main control chip is connected to and controlled by a transistor.

[0032] The fourth embodiment of this utility model is largely the same as the first embodiment, mainly in further detailed optimization to improve overall stability and durability, with the NCDR port of the battery protection chip connected to the main control chip.

[0033] Furthermore, the protection circuit incorporates a three-terminal integrated voltage regulator, which outputs a 5V voltage. This 5V voltage is connected to the positive terminal of the array LED beads, and a branch of the three-terminal integrated voltage regulator is connected in parallel to the voltage detection terminal of the main control chip. This further enhances the product's operational stability.

[0034] Furthermore, in the protection circuit, a PNP transistor is connected to the link between the positive input terminal and the voltage output. The collector of this PNP transistor is connected to both the positive input terminal and the ADC pin of the main control chip. Voltage divider resistors are connected in series on the links between the positive input terminal and the ADC pin of the main control chip to the collector of the PNP transistor. Thus, the current intensity can be controlled by the ADC, thereby controlling the light intensity of the array LEDs and avoiding the problem of high-frequency flickering of the LEDs caused by PWM control mode, which may be harmful to the user's eyes.

[0035] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
