SMD2835 Sign Module Mock-Up: Set Box Depth and Module Pitch Before Ordering

A 160-degree module does not determine spacing by itself. Build one representative sign section with the actual face, return depth and reflective interior, then use the approved layout to calculate module count and the 30W, 2.5A load of each published 20-module string.

The buyer decision is not modules per square metre in isolation. The approved variable is a layout that works with the actual face transmission, return depth, stroke width, internal reflection and normal viewing distance.

Approve one representative letter or lightbox section

Build the most difficult stroke, corner or shallow area with the final face material. Compare at least two module pitches under the same exposure, then mark the accepted positions on the production drawing.

Judge hot spots from the normal viewing path and check the cabinet after warm operation. The 160-degree optical value widens distribution, but it does not replace a mock-up because face opacity and depth remain project variables.

Find the hardest area before setting module pitch

Hot spots usually appear first where the face is shallow, a stroke narrows or a corner changes reflection. A generous beam angle cannot guarantee uniformity when these geometric conditions change.

Use the most difficult section as the approval sample. If it passes with the final face and interior finish, simpler areas can follow the documented layout; if it fails, adjust pitch or depth before ordering quantity.

Box depth, face transmission and interior finish work together

The published 160° output spreads light broadly, while the actual mixing distance is set by the cabinet. A shallow return or translucent face may expose individual modules even when the electrical layout is correct.

IP65 applies to the published module, not automatically to field joints, wire entries or the sign enclosure. Place joints for drainage and service, and inspect the complete cabinet rather than treating the module rating as system protection.

Calculate each 20-module string before assigning circuits

At 1.5W per module, 20 modules equal 30W. At DC12V this is 2.5A theoretically before cable and connector losses; two such strings are 60W and 5A.

Use the approved drawing to count modules per letter and zone. Then size parallel circuits, cable and supplies from the actual count and route, followed by a loaded-voltage check at the farthest module.

Separate optical layout from the published string format

The page identifies a DC12V SMD2835 sign module, 1.5W per module, 20 modules per string, 160° output and IP65. Twenty per string is a supply format, not a rule that every letter must use a complete string.

Cutting, reconnecting and maximum modules per circuit must follow the released wiring and marks. The mock-up determines spacing; the electrical drawing determines how accepted positions are grouped into serviceable circuits.

Quick project decision table

Control zones and effect requirements

Choose uniform zones for simple colour changes and pixel data control only when the project needs independent movement. Controller limits remain configuration-dependent.

Where this LIKELIGHT module fits

The product case belongs after the decision method: LIKELIGHT can evaluate spacing, circuits and connections from the final drawing.
