Different SEG Light Boxhas different power, what if you don't know the relative power? You can do this by estimating, so how does the SEG Light Box estimate power?

The first way to estimate the power of the SEG Light Box is to estimate the power by estimating the current. Assuming that each string of current is 20 ma, the approximate power of each string is the value of voltage times the current of 4.4 W. The second method is to estimate the power of the SEG Light Box based on the number of beads per string. This method is rather cumbersome. First, the number of beads per string must be known, and then the power of the different colored beads must be calculated separately, and then you add them together.

Take the most commonly used UV film SEG Light Box, the general use is 2835 shutter lights, 5730 shutter lights, and 3030 diffuse Light strips. Do a regular thickness of 8cm cabe light box, size 1 * 1m, brightness requirements are general, use 2835 shutter lamp, for shutter lamp, the distance between the lamp strips is less than the thickness of the light box will not have ribs, in order to ensure uniform brightness, we use 6.5 cm distance between strips, the number of strips used is 15, different brands of strips, the number of beads is different, the power is also different, we take the median value of a single strip 6W, a Square Cabo light box is about 90 watts.

In the same standard case, use 3030 diffuse strips, diffuse strip luminous angle of 170 degrees, strip spacing can be larger, we can use 15 cm spacing, the number of strips used is 7, the power of a single strip is 12W, so the power of a square is 84W.

If the brightness of the SEG Light Box is very high, you can use a 5730 shutter lamp, the same 6.5 cm distance between the lamp strips, a single strip of power is 10W, and a square of power is 150W, although the power is improved a lot, there was also a big increase in brightness. Using 3030 diffuse strips, just reduce the strip spacing, diffuse strip spacing to 10 cm is also super bright. A power squared is 120W.
