Problems solved by technology

The disadvantages of using this method are: 1) The structure is complex, and it is difficult to provide a high protection level; 2) When setting the output operating parameters, the driver needs to be connected to the input power supply, load and power meter, and be in a working state, so that the user can see Whether the set parameters are reasonable; 3) If you want to set multiple time periods to work, and each time period works with different parameters, this method is difficult to achieve
[0004] The "four-in-one dimming circuit" proposed by Chinese patent CN103152939A can easily set the LED drive power supply to work in different states by downloading the program. For the dimming input port (2 wires), the structure is more complicated and the cost is higher

Embodiment Construction

[0038] In the following, the present invention will be described in detail and specifically through specific examples, so as to better understand the present invention, but the following examples do not limit the scope of the present invention.

[0039] In order to match different types of LED light sources, users usually need to choose LED drivers with different output voltages and currents; if the output voltage and output current of a driver can be adjusted within a certain range, it will undoubtedly bring great convenience to users In addition, in the actual use of LED drive power, in some occasions that have different requirements for luminous flux or reduce power operation in a specific period of time to achieve energy-saving requirements, LEDs are required to be able to achieve dimming.

[0040] Such as figure 1 As shown, by connecting the programming controller with the LED drive power supply, even if the drive power supply is not powered on, the dimming line of the dr...

Abstract

The invention provides a programming setting circuit for setting the output parameters of LED driving power supply, which is located in the programming setting controller connected with the LED driving power supply, including a microcontroller main power supply unit, a microcontroller, and a dimming signal processing unit , an output voltage setting circuit, an output current setting circuit, an output voltage feedback processing circuit, an output current feedback processing circuit, and also includes: a communication signal interface circuit, and a working status indicating unit. The invention can achieve the purpose of setting the output parameters of the driving power supply through the dimming line, thereby simplifying the structure of the power supply, reducing the overall cost, and greatly facilitating the setting of the working parameters of the power supply, and even upgrading the inside of the power supply through the dimming line. firmware of the microcontroller, and the dimming operation is not affected in any way when the power supply is working normally.

Description

technical field [0001] The invention belongs to the field of LED lighting drive power supply control, in particular to a programming setting circuit for setting output parameters of the LED drive power supply. Background technique [0002] As the most popular lighting source at present, LED is being used more and more widely. According to the working characteristics of LED semiconductors, in order to guarantee the working reliability and facilitate the control, the driving power used usually adopts the type of constant current output. When the driving power supply increases the operating current provided to the LED light source, the luminous flux will increase, and vice versa, the purpose of dimming can be achieved by adjusting the forward conduction current of the LED. In addition, when the user purchases a batch of LED drive power supplies, they may match different LED light boards, that is, it is possible to match LED light boards with different numbers of series and par...
