The first item that you need is the UV LED chips. These chips emit light in the ultraviolet spectrum, which is invisible to the human eye. You can purchase these chips online or from a local electronics store. It is essential to select the right type of UV LED chips for your project because different chips emit different wavelengths of light. The wavelength of the UV light that you want to produce will depend on the application that you have in mind.

Printed Circuit Board (PCB)

The next item that you need is a PCB. This will be used to connect the UV LED chips together. A PCB is a board made of non-conductive material that has copper traces on it. These copper traces are used to connect the components together. You can purchase a PCB online or make one yourself. If you decide to make a PCB yourself, you will need to use a software application to design the PCB layout and then print it out on a special type of paper.

Soldering Iron and Solder Wire or Paste

The soldering iron and solder wire or paste are used to connect the components together. A soldering iron is a tool that heats up and melts the solder wire or paste so that it can be used to connect the components together. When working with UV lights, it is essential to use lead-free solder because lead is toxic and can cause health problems.

Wire Cutters

Wire cutters are used to cut the wire to the correct length. This is important because the length of the wire will affect the amount of current that flows through the circuit. If the wire is too long, the current will be reduced, which will reduce the amount of UV light that is produced.

UV Resistant Glasses

UV resistant glasses are essential to protect your eyes from the UV light. UV light is harmful to your eyes and can cause damage to your vision. It is important to wear UV resistant glasses when working with UV lights.
