![]() ![]() As mentioned, creating a smooth uniform glow with limited LED space, a small number of LED’s and light across surfaces in 5+ directions is very challenging. My suggestion would be to design a more local lightpipe area that would still meet your need, and creating that outside housing as 2 pieces or a two shot part (opaque over clear). ![]() If the main housing is opaque, that type of light pipe would just give you some soft illumination on the top surface at best. If you want a better idea of the approach to use and can share a cross section of where your PCB is and where you want to illuminate its sometimes easier to sketch.Īgreed that trying to evenly light an area that large especially if it’s just a cover will be challenging (not impossible, but challenging!) Once you have a rough idea, then you can move to a 3D printed part (it may need to be hand polished) or a cast urethane part. I’ve done experiments using Keyshot raytracings to try and simulate some of the effects, but generally the renderings take forever and are still only so accurate. If the LEDs are at an angle or awkward position, then you would have to look at actually building a pipe to try and route the light up which is a bit more complex. If you can get the LEDs laid out on the board where they all consistently intersect with the surface you want to light up, then you likely don’t need any “pipe” features at all. You want the positioning of the LEDs to be enough where you have a slight overlap of each cone (since there is falloff from the center to the outside of the cone). If the LED is shining straight towards the surface that will be fairly easy. The easiest way to get a rough estimate of this working is to find the cone of your LED (ex 60 degrees) and model it into your CAD model so it’s shining out of the LED. It’s hard to tell the desired effect and complexity from the photo you posted, but in general good light dispersion requires - the right LED (with a cone that matches the intended illumination area), the right plastic to either diffuse the light (we used a lot of Lexan FXD materials for light pipes since they could be milky to diffuse light better), and the right distance from the PCB for the cone to spread to hit the intended area. When users need visual representation of their scan, design, modifications or 3D print, KeyShot provides the quality they expect.There is optical analysis software that can do complex raytracing and calculate this, but we’ve always had an optical engineer who spent most of their days designing lenses for that level of complexity. ![]() The software has been optimised for more efficient 3D printing and users can export full-colour rendered models directly from Keyshot into the 3D Systems’ ProJet 圆0 line of Color Jet Printers for realistic models.Ĭlaus Jensen, CEO and Co-founder at Luxion, added: “With 3D Systems’ seamless workflow from physically to digital print creating product visuals can now easily be done throughout that entire process. Engineers will love having KeyShot’s world-class rendering as part of their Geomagic software.” Designers will now be able to create stunning imagery with a simplified piece of technology that breaks down the complexity of producing photographic images from 3D data.Ĭalvin Hur, VP and GM of Geomagic Solutions at 3D Systems, said: “We are reimagining the engineer’s desktop with our complete line up of solutions for Scan-based Design, mechanical design and haptic-enabled freeform design. KeyShot is the first real-time ray tracing application that uses a physically correct render engine based on scientific research on material representation and illumination. The partnership is set to establish Luxion’s proprietary KeyShot technology as the standard rendering solution incorporated in selected 3D Systems’ Geomagic software packages. Leading developer of advanced rendering and lighting technology, Luxion, has announced a new partnership with 3D printing stalwart 3D Systems. Luxion KeyShot now features in select 3D Systems' Geomagic software. ![]()
