Custom Injection-Molded LED Diffuser Covers
Develop translucent LED covers and diffusers around the LED layout, viewing distance and finish you need. Agree on lit and unlit sample checks before release.
Choose the optical job first
Explain whether the part should soften visible LED points, pass as much light as practical, or support a specific appearance while unlit. Resin grade, cover thickness and finish belong in the same brief. Add the actual LED layout and the gap between the LEDs and cover.
Set separate lit and unlit references
Check unlit color, texture and visible marks under an agreed light source. For the illuminated check, keep the LED board, drive setting, viewing angle and distance the same from sample to sample. If a numerical optical requirement is necessary, record the method and specimen thickness.
Check the diffuser rim with the mating housing
Provide the rim geometry, retention method and relevant mating parts. Agree which edges must sit flush and how gaps or light leakage will be assessed on the assembly. Keep the approved sample and its associated material, finish and drawing revision together.
Frequently asked questions
Does the resin data sheet predict how my assembled lamp will look?
Use the data sheet to compare candidate grades at comparable test conditions. Approve the appearance with a molded cover on the intended LED board and housing.
Can I request a matte cover?
Include a matte reference and mark the surfaces that need the finish. Confirm the lit appearance and cover fit during the project review.
