UV Exposure Box (D.I.Y.)




Introduction: UV Exposure Box (D.I.Y.)

Hello everyone,

My name is Michalis and this is my first attempt to make an instructable!

This is an instructable for a uv exposure box(actually a UV-A exposure box)!!!

UV exposure is used for reasons such as:

1)curing loca glue(repair touchscreens!!)(need a little bit more time than flurecent tubes)

2)cleaning water from bacteria(better with uv-c)

3)hand dryers(new dryers that flow air and emmit light to dry your hands after washing them)

4)photoresistive pcb`s making(one of the best ways for making photoechant pcb`s)

5)nail uv gel curing

Special caution should be given to the fact that uv light is harmfull for skin and eyes(no to such low exposure, but it is better to be carefull after all!)

ohh, and do not forget to make stickers like these in the photos to warn people about safety and uv light!

Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Matterials Needed!

1-the uv lamp,in my case i use a philips HPL-N125w

2-a ballast 125watt


4-hinge for the box lid

5-something to keep closed the box

6-On/Off Mini Micro Leaf Door Switch

7-wood for the box...better to be 15mm

8-on off switch


10-E27 lamp holder

Step 2: Make the Box!

i don`t have pictures of the process, but you can see the results here..

Step 3: Placing All of Our Matterials in the Box!

the ballast has one ''input'' and one ''output'' it does not matter how you will connect it, so our power (the phase..the one cable ) goes to the on-off switch and then from the switch a cable goes to the ''door'' switch in order to protect ourselves when the ''door'' is open!

Now,from the door switch a cable goes to the ballast and from the output of the ballast we take a cable to the lamp holder.

now we have the other cable(neutral) that goes straight to the lamp holder.

Step 4: Finished...

this switch opens and closes with the door ,as you can see when door is closed(i did it manually here) the lamp goes on!!!this is my uv exposure box...

thank you very much for your patience and your time

pm:i know that my intructuble is very poor,i hope to fix this soon...

    Interesting! I've only seen fluorescent tubes used for UV. What are you exposing to the light?

    Thank you for your comment! for pcb making it is ideal, the spectrum is between 370+nm so we don`t have so much uv light really, but pcb`s photoetching can be done easily by this way!!! i have also tried loca glue( http://en.wikipedia.org/wiki/Liquid_optically_clear_adhesive ), but it cures very slowly and poorly....

    This is a good idea for people who work around UV. Even low-power bulbs can be harmful with prolonged exposures.

    • UVA rays. These are closer to visible light rays and have lower energy than UVB and UVC rays. But UVA rays can pass through the cornea and reach the lens and retinainside the eye.

      Overexposure to UVA radiation has been linked to the development of certain types of cataracts, and research suggests UVA rays may play a role in development of macular degeneration.

    Various eye problems have been associated with overexposure to UV radiation.
