[0003] At present, the control circuit of the common LED shoe light product in the market adopts simple analog circuit or basic digital logic circuit. The scheme performs poorly in power consumption control, that is, most products lack intelligent power management mechanism, and once turned on, the power consumption is continuous, or the user needs to manually turn off, which is easy to cause the power to be quickly consumed due to forgetfulness. The scheme of completely cutting off power by mechanical switch can solve the standby power consumption problem, but the operation is complicated, and the user experience is poor, which makes the product need to replace the battery frequently, seriously affects the use convenience and user satisfaction. For the shoe light using small power supply such as button cell, this problem is particularly prominent. UTILITY MODEL CONTENT
[0004] In view of the deficiencies in the prior art, the utility model aims to provide a LED shoe light control device to solve the technical problem of excessive energy consumption of the existing shoe light product.

[0006] The control chip has sleep and work dual modes, and the trigger switch, mode total switch and LED lamp group are connected with the pins of the control chip.
[0007] When the mode total switch outputs the first level to the control chip, the control chip is awakened from the sleep mode and enters the work mode in response to the single trigger signal generated by the trigger switch, and automatically executes a pre-stored color light effect sequence with fixed time length through the LED lamp group, and returns to the sleep mode automatically after the sequence is executed; when the mode total switch outputs the second level, the control chip is prohibited to respond to the trigger switch.
[0008] Further, the control chip is integrated with power pin, ground pin, LED drive pin, OS signal input pin and ON-OFF control pin.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments. Specific implementation method one:
[0027] This embodiment is described using the example of a control chip 1 having three LED driving pins and using three LEDs. However, those skilled in the art should understand that the technical solution of this application is by no means limited to the specific number and color configuration of the LEDs mentioned above. Its protection scope covers various changes and adaptations to the number and type of light-emitting units, and the duration and number of cycles of the colored light effect sequence can be changed as needed.
[0028] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a technical solution for an LED shoe light control circuit:
[0029] A control chip 1 with both sleep and working modes, a trigger switch 2 connected to the pins of the control chip 1, a mode master switch 3, and an LED light group 4;
[0030] When the mode switch 3 outputs the first level to the control chip 1, the control chip 1 is woken up from the sleep mode to the working mode in response to the single trigger signal generated by the trigger switch 2, and automatically executes a pre-stored color light effect sequence with a fixed time length through the LED lamp set 4, and returns to the sleep mode automatically after the sequence is executed; when the mode switch 3 outputs the second level, the control chip 1 is prohibited from responding to the trigger switch 2.
[0031] 1. Control chip 1:
[0032] The control chip 1 is the control core of the whole circuit, and pre-stores a fixed color light effect program inside, which can be divided into working mode and sleep mode:
[0033] In the working mode, the control chip 1 is in full-function running state, at this time, the logic control unit inside it outputs the driving signals with specific time sequence and duty cycle on the three LED driving pins according to the pre-stored program through the internal timer and PWM (pulse width modulation) generator, these signals drive the external LED lamp set 4 to present the color light effect sequence with fixed time length according to the preset logic (such as color mixing, flashing, water flow, etc.), the chip power consumption is relatively high in this mode, but it is only activated during the execution of the preset sequence with limited time length;
[0034] In the sleep mode, the control chip 1 closes most of the functional circuits related to light driving and effect logic inside, only a very small part of circuit necessary for monitoring the OS signal input pin and ON-OFF control pin is reserved, in this state, the chip power consumption is reduced to a very low static level (typical value not more than 1 μA), thereby realizing ultra-low power standby, this mode is the default state after the chip is powered on, and is also the automatic destination after each light effect sequence is executed.
[0035] 2. Trigger switch 2:
[0036] The trigger switch 2 is a single effect triggering mechanism in this circuit, which is usually a light touch button switch, one end of which is connected to the OS signal input pin of the control chip 1, and the other end is grounded, and its working principle is as follows:
[0037] In the static state, the control chip 1 connects the OS signal input pin to the power supply VCC, so that the pin is stably clamped at high level. When the wearer steps or manually presses, the button of the trigger switch 2 is forced to close instantaneously after being pressed, forming a low impedance path, which forcibly pulls the level of the OS signal input pin from high level to ground level, thereby generating a clear falling edge signal.
[0038] The falling edge signal is recognized by the edge detection circuit or interrupt service program built-in the control chip 1 as an effective wake-up event and start instruction, which can timely inform the control chip 1 that there is an external triggering event, and then drive its internal logic: first, wake up the chip from the super-low power sleep mode, then start its system clock and logic unit, enter the working mode, and start executing the pre-stored color light effect program.
[0039] It is worth noting that this triggering mechanism is single and level sensitive, as long as the trigger switch 2 remains closed, the OS pin will remain low, but the chip will only respond once at the falling edge, and subsequent continuous low will not cause the program to trigger repeatedly, which effectively prevents misoperation caused by switch jitter or long pressing, and ensures that each trigger corresponds to a complete light effect sequence mode total switch 3.
[0040] 3、Mode total switch 3:
[0041] Mode total switch 3 is the key component of this circuit for intelligent power management and user interaction, although it is the same as trigger switch 2 in hardware form (i.e. both are light touch buttons), but it realizes complex control of global function enablement by cooperating with completely different software logic inside the control chip 1, its core working principle is based on level detection and internal state latching mechanism, not the edge detection mechanism used by trigger switch 2;
[0042] One end of mode total switch 3 is connected to the ON-OFF control pin of control chip 1, and the other end is grounded. In the chip, this pin is usually set to high level by a pull-up resistor, so when the button is not pressed, the ON-OFF control pin is maintained at high level. When the button is pressed, the pin is pulled low to low level instantaneously, generating a low level pulse.
[0043] The firmware program of control chip 1 configures level detection and state latching logic for the ON-OFF control pin, that is, when the ON-OFF control pin is low, it means that the system function is allowed (enabled state), in this state, the control chip 1 can normally respond to the wake-up signal of trigger switch 2; when the ON-OFF control pin is high, it means that the system function is prohibited (disabled state), in this state, the control chip 1 will ignore any trigger signal unconditionally, and immediately or always maintain in sleep mode, thus realizing physical level function shutdown.
[0044] This logic does not care about edge changes, but continuously monitors the level of the pin, and switches an internal, non-volatile system enable state flag according to a specific low level pulse:
[0045] 4、LED lamp group 4:
[0046] LED lamp set 4 as the final light effect output unit, it is composed of at least three LED lamps (the color of the LED lamp can be multiple or single), respectively connected to the three independent LED drive pins of control chip 1, through receiving the PWM drive signal carefully arranged in time sequence and duty ratio by control chip 1, each color LED is mixed at different brightness levels, finally the colorful multicolor flashing effect is presented in the human eye.
[0047] 5, power module:
[0048] The power module is to provide stable and continuous power for the whole circuit, which usually adopts a button cell or a micro lithium battery to meet the miniaturization and light weight requirements of the shoe lamp product, and its wide voltage working range (2.0V-5.5V) ensures the stable operation of the circuit under different battery capacities.
[0049] The circuit of the application ensures that the device can achieve optimal power consumption management in any possible use scenario: during normal use, the first line of defense constituted by the return to sleep mode after the execution of control chip 1 ensures no function waste; when long-term idle, the second line of defense constituted by the high level applied by mode total switch 3 to prohibit control chip 1 from responding ensures no standby loss, the two work together to make the device using power module can realize long standby.
[0050] In addition, the circuit also makes full use of the software flexibility of control chip 1, uses two completely same low-cost hardware buttons, through different internal programming, realizes two complex functions of mode switching and effect triggering, greatly simplifies the material management and assembly process, reduces the production cost, at the same time provides clear, intuitive and complete function for the user Interactive experience. Specific implementation method two:
[0052] As Figure 4 The utility model provides a kind of technical scheme of LED shoe lamp control device:
[0053] A kind of LED shoe lamp control circuit device, the device is shoe lamp, it encapsulates the LED shoe lamp control circuit in a shell, the shell is arranged in the position of shoe body easy to be pressed or easy to contact, to facilitate through wearer step triggering to execute the color light effect sequence.
[0054] The shell is usually made of ABS, PC (polycarbonate) or translucent TPU (thermoplastic polyurethane elastomer) and other engineering plastics by injection molding process, its design needs to take into account lightweight, structural strength and certain light transmittance, the shell is provided with a clamping groove or a bracket for fixing a printed circuit board (PCB) to ensure stable operation under severe motion; the power module (such as a button cell) is usually placed in the battery slot specially designed in the shell, and is in stable contact with the PCB through a metal spring, the battery slot cover is designed with an anti-lost screw or buckle for facilitating user to replace the battery.
[0055] The device converts a complete electronic control system into a solid, durable, sealed and easy-to-install independent lamp module through ingenious structural design, the highly integrated plug-and-play design greatly facilitates the production and assembly of footwear manufacturers, and ensures that the final product can still maintain long-term stable working performance and excellent visual effect when facing the harsh environment of bending, impact and sweat in daily wear.
