Detailed Description

The following examples are intended to illustrate the present invention in detail and should not be construed as limiting the scope of the present invention in any way.

The programs referred to or relied on in the following embodiments are all conventional programs or simple programs in the art, and those skilled in the art can make routine selection or adaptation according to specific application scenarios.

The unit modules, components, structures, mechanisms, sensors, and other devices referred to in the following examples are all conventional commercially available products unless otherwise specified.

Example 1: the utility model provides an LED controller of accessible cell-phone control, refer to fig. 1 to 5, includes power module, bluetooth module, drive module, and power module is used for wireless communication module and drive module power supply, and drive module and LED lamp electricity are connected, and drive module and wireless communication module's output corresponds and connects.

During the use, bluetooth module and terminals such as cell-phone are interconnected through wireless mode, then the terminal sends the order to bluetooth module, and bluetooth module transmits this order for drive module, by the luminous effect of drive module according to this order control LED lamp.

The power supply module comprises three parts, namely a voltage reduction unit, a voltage stabilization unit and a voltage boosting unit, wherein the voltage reduction unit adjusts external power supply of a P1 interface into 3.3V and 4.3V output for supplying power to the wireless communication module, and in order to ensure voltage stability, the voltage reduction unit is connected with a voltage stabilizer XC6206P332MR, so that the performance of the communication module is prevented from being influenced by voltage fluctuation. Because the voltage and the current required for driving the LED are relatively high, the boosting unit is arranged behind the voltage reduction unit to supply power to the driving module, and the boosting unit adopts a boosting current type PWM chip ME2159A to boost the driving current to be matched with the specification direction of the LED.
