High power 290nm, 305nm, 285nm, 325nm, 335nm 340nm, and 355nm Gemstone Inspection UVB LED PCBA module
UV-B based LEDs are a relatively new technology. Examples of wavelengths currently commercially available include 290nm, 305nm, 285nm, 325nm, 335nm 340nm, and 355nm However, UV-B LED technology is rapidly developing, and over time new wavelengths will be developed, costs will reduce and efficiencies will increase as has already happened within the red, infrared, blue, and UV-B wavelength LED ranges.
UVB LEDs vs. Traditional Technologies
Many applications use Mercury based UV lamps for UVB LIGHTING applications but this technology has a number of disadvantages versus LED technology. There is increased regulation around mercury usage and its environmental impact resulting in increased disposal costs and proposed bans in some countries. These systems also require the use of chlorine to enable disinfection and are typically much larger than LED-based systems.
Why UV LEDs
With an increase in the type of ultraviolet (UV) light applications, the specific requirements for various industries are growing and there is a greater emphasis on higher light output, better thermal management, greater flexibility, and more adaptability. Companies require sophisticated, customized solutions to revitalize their business and industries such as horticulture, curing, and disinfection are making significant changes as they see a growth in research and development in UV technologies. While ultraviolet light has been used extensively for more than 40 years, ultraviolet light-emitting diodes are a promising entry offering a more sustainable solution than the incumbent lamp technologies. UV LEDs have risen to answer the current technological limitations with mercury lamp sources and hold the key to growth in industries worldwide. With a flexible form factor and an inherent ability for intensity and spectral control, UV LEDs can be integrated into various systems across several different applications.

When clients need to design a new circuit or modify an existing one
We follow the following process:
Engineers will have discussions with clients to identify their product requirements and specification requirements.
Components Selection
We select the most suitable components based on the customer’s requirements, such as LEDs, protection devices, thermistors, resistors, capacitors, inductors, etc.
At the same time, we also consider factors such as component availability, cost, and reliability.
Circuit Design
Engineers design circuits based on customer requirements and selected components
Includes drawing circuit diagrams and determining circuit dimensions
PCB Design
After completing the circuit design, we will start the PCB design to convert the circuit diagram into the actual PCB layout to ensure the correctness, reliability and performance of the circuit.
Production documents
Finally, we generate the necessary files for the manufacturing of the product, e.g. Gerber file, 2D CAD, BOM list for mass production

Warmth Hint: The company is willing to personalize your customized products.
The greater the irradiation dose, the higher the disinfection efficiency.
The higher the UVB light power, the shorter the time required to kill bacteria and viruses, and vice versa, the lower the light power,The longer it takes to sterilize.
