This device is made for illuminating printed circuit boards that are sensitive to light, the so-called printed plates for the photo process. The special feature of this device is that it is very light and easy to carry from one place to another. To illuminate printed circuit boards, we use UV LEDs, which, unlike halogen bulbs, are less powerful and heat up less. In order to prevent a harmful effect on human eyes, there is a lid on the coffin that prevents this, and a time timer is also built in, which allows us the exact lighting time. When the illumination is finished, the sound and light signal on the lid of the coffin informs us about it. A Led screen is installed on the trunk lid for easy navigation.
