realUV™ LED strip light grid array spacing for even exposure

I'm building my own UV LED strip light array for emulsion exposure with a panel size of 30" x 15", and am thinking of using 10 rows of your realUV™ LED strip lights in 365 nm with each row being 15 inches in length. The LED array will be approximately 3 inches from the exposure surface. How far apart can the LED strip rows be without any gaps in UV irradiance?

The LEDs emit the UV radiation at a 120 degree angle. This generally means that the LED strips should not be spaced farther apart than the distance away from the irradiance surface. In other words, if the exposure irradiance surface is 3 inches away, the LED strip lights should not be spaced farther than 3 inches per row, on center.

Based on your proposed UV LED strip array panel size, dividing the 30 inch length by a total of 10 rows will ensure that the distance between the LED strip rows will remain less than 3 inches each. Since we are within the 3 inch limit, there should not be concerned about uneven UV irradiation.
