Description

A portable, integrated, stand-alone power supply module UV-LED lamp and its control method Technical Field

[0001] This invention relates to the field of portable UV-LED lamp technology, and more specifically to a portable, integrated, independent power supply module UV-LED lamp and its control method. Background Technology

[0002] UV-LED lamps are frequently used in the market, with a wide power range, generally from 100W to 20KW. Due to current limitations in UV-LED chip manufacturing processes, these high-power lamps typically consist of multiple 300W-1000W lamp modules connected in series and parallel. Currently, there are two types of driver power supply solutions for these multi-module UV-LED lamps:

[0003] The first type of solution involves multiple external UV-LED drivers that drive multiple internal UV-LED modules (as shown in Figure 1). This solution requires an external power cabinet to house the multiple UV-LED drivers, resulting in a large footprint and high cost. Furthermore, it necessitates multiple power lines to the inside of the luminaire, leading to complex and cumbersome wiring. The cost increases significantly, especially when the power cabinet is located far from the luminaire. Additionally, this solution cannot monitor the temperature of the UV-LED modules via the power supply, typically requiring an additional temperature detection module.

[0004] The second approach involves an external high-power power supply and multiple internal low-power linear shunts (as shown in Figure 2). This approach still requires an external power cabinet to house the high-power power supply, and the external high-power power supply needs to be adapted to the power of the lamp; otherwise, it will result in power waste and is not flexible in configuration. The linear shunts have lower efficiency, and the energy undergoes a two-stage conversion, resulting in even lower overall efficiency.

[0005] In addition, the driver power supply solutions for these UV-LED lamps are all bulky and inconvenient to carry, making them unusable in some scenarios and causing a lot of trouble for users.

[0006] Therefore, existing UV-LED lamp technology needs further improvement to address the above issues. Summary of the Invention

The matrix lamp circuit consists of n LED modules and n high-frequency switching constant current circuits. These high-frequency switching constant current circuits are also known as high-frequency switching constant current board circuits (as shown in Figure 5). Users only need to connect three-phase AC power, greatly simplifying wiring and eliminating the need for a dedicated external electrical cabinet, thus saving floor space. The three-phase power input circuit, EMC filter circuit, three-phase rectifier filter circuit, input detection circuit, phase loss detection circuit, and voltage detection circuit are combined into an LED lamp headboard. Multiple high-frequency switching constant current circuits within a single lamp share one lamp headboard, significantly reducing costs.
