Problems solved by technology
However, after the existing LED lamps are installed in the same place, they usually can only display fixed brightness, color temperature and color, and can only be turned on and off as a whole. LED lamps are in a state of high brightness and high color temperature for a long time, which will cause damage to the life of the power supply and lamp beads, which is not conducive to the long-term stable use of LED products

The invention discloses an intelligent constant-current power supply applied to an LED product. The intelligent constant-current power supply comprises a Bluetooth module having a networking function,an AC / DC main power supply circuit and a Bluetooth power supply BUCK circuit, wherein an intelligent control port is embedded into the Bluetooth module and is used for adjusting a pulse width modulation (PWM) output signal, the AC / DC main power supply circuit comprises an LED constant-current controller, a resistance branch, a rectification bridge BD1, a capacitor C1 and an inductance-capacitanceseries branch, the LED constant-current controller is connected with a PWM output end of the Bluetooth module via a pin 1, the resistance branch is connected with a pin 4 of the LED constant-currentcontroller, the rectification bridge BD1 and the capacitor C1 are connected with the resistance branch, the inductance-capacitance series branch is connected in parallel with the capacitor C1, an input end of the rectification bridge is connected with a piezoresistor RV1, and the Bluetooth power supply BUCK circuit is connected with two ends of the capacitor C1. By integrating a Bluetooth MESH technology and the LED power supply, an LED lamp at an output end of the same power supply can be used for flexibly adjusting and controlling according to intention of an operator, lighting is achieved,more energy is saved, environmental friendliness is achieved, and the effects of embodying decoration and beautifying an environment are achieved.
Description
technical field [0001] The invention relates to an LED power supply, in particular to an intelligent constant-current power supply applied to LED products and a control method thereof. Background technique [0002] With the rapid development of science and technology, LED products are constantly developing and replacing. People's initial requirement for LED products is to realize energy saving while realizing lighting. Now, with the increase and change of application scenarios of LED products, people's demand for LED products The requirements are no longer just for lighting and energy saving, but also for technical indicators such as brightness, color temperature, and color of LED products. However, after the existing LED lamps are installed in the same place, they usually can only display fixed brightness, color temperature and color, and can only be turned on and off as a whole. The long-term high brightness and high color temperature of LED lamps will cause damage to the...
