Embodiment Construction
[0015] Below in conjunction with accompanying drawing, describe in detail, as figure 1 As shown, a disinfection and deodorization device based on a single-chip microcomputer and an ultraviolet LED array includes a circuit substrate, an ultraviolet LED light source, an ultraviolet filter, an LED drive circuit, an MCU controller, a single-chip microcomputer control unit, a heat dissipation unit, and an active catalyst layer.
[0016] As for the circuit substrate, a double-sided copper foil structure is adopted, and the inner core lining can be made of metal or ceramic material to further enhance heat dissipation. Arrayed LED device support sockets are arranged on the circuit substrate, and multiple groups of ultraviolet LED light-emitting source devices can be selectively installed. Each array point has a unique strobe address line, and its strobe principle is similar to the data bit access of random access memory, which is well known to those skilled in the art and will not be ...

Abstract
A control system of an ultraviolet LED array based on a single chip microcomputer comprises a circuit substrate, an ultraviolet LED luminous source, an ultraviolet ray filter lens, an LED drive circuit, an MCU controller, a single chip microcomputer control unit, a heat dissipation unit and an active catalyst layer.An 89C52 series single chip microcomputer is adopted in the single chip microcomputer control unit, and the combination of a PIC series single chip microcomputer and an output port extended chip can also be adopted.A 5V power supply is adopted for the single chip microcomputer control unit, a 4*4 array keyboard is adopted for inputting, the keyboard comprises the number keys of 0 to 9, a reset key and function keys, and a four-bit LED digital tube is used for input displaying.An additional 8-bit data bus is used for gate control over the LED array, the work LED number is set through the keyboard, and the single chip microcomputer controls a gating unit to work.
Description
technical field [0001] The invention relates to a design method of a control system of an ultraviolet LED array based on a single-chip microcomputer. Background technique [0002] As an important means of disinfection, ultraviolet light has been widely used in various fields. However, the traditional ultraviolet mercury lamp has slow response speed, high energy consumption, heavy burden on the driving circuit, high heat generation, and it is difficult to make a control array due to the problems of volume and power, which affects the control efficiency. [0003] Ultraviolet LEDs generally refer to LEDs with a central wavelength of light emission below 405nm. In the LED industry, light emission wavelengths between 355nm and 405nm are generally called near-ultraviolet LEDs, and those shorter than 300nm are called deep ultraviolet LEDs. At present, GaN, the most widely used material in LED research and production, has a forbidden band width of 3.4eV and a corresponding emission...
