I need to illuminate 4 apertures with a solid block of light using individual LEDs (similar to the attached photo). It seems like putting a polished concave cut into the back of the shafts would help spread the light. However I don't think this alone will be enough to achieve the sleek effect I'm looking for. Does anyone have any design tips for this kind of thing? For assembly purposes, I want the 4 LEDs to sit on the same PCB. Thanks
