Next generation automotive lighting system

1. Moving towards a digital solution to realize new possibilities
2. Lighting solutions – working digitally to innovate without compromise
3. Rear Lighting analysis – solutions that opens more possibilities
4. Results that gives 100% confidence to manufacturers, R&D designers in achieving wide functional surfaces on large surfaces
5. Cycle time of the overall process 
6. Thermal simulation: Temperature distribution over the Mold & molding surface
7. Laser technology for next generation advanced lighting solution: summary

The Lighting in the automotive goes beyond the "SAFETY" of the Driver and stands distinctive signature of "BRANDING" appeal. Advanced functions for Exterior, Interior to ensure "MOODS" of the occupants in addition to the driver smooth driving. Advanced lighting technologies supports "EMISSION & MILEAGE" by using less power with technologies ranging from Light Curtain, LED & Matrix LED, Ambient Lighting with more sensors & cameras. Functional surfaces are necessary to realize on the final parts providing aspects of visibility, comfort & Appearance.

This put pressure on the Lighting designer & the ability of Mold maker to produce final injected parts to replicate functional surfaces that provide perfect Optical efficiencies.

The Rear Lighting example as above will give a clear understanding.

Mold sample with laser texture (Fig1.) & the Final injected plastic part (Fig 2.) displayed in the recent EMO -2019 show in Hannover. GF MS created unique textures to replicate real life application done together with our business partners.

GF Machining Solutions Laser technology comes with a choice of laser source (pulse duration, power, and texturing pattern) that is driven by the desired surface that the manufacturer wants to produce. Lasers that operate with a "Nanopulse" duration will both ionize metal and locally heat the surface being treated, resulting in a surface with an increased Sdr, Vvc and Vvv as compared to femtosecond lasers. "Femtosecond, FemtoGreen pulses" are much shorter and essentially eliminate the heat-affected zone (HAZ), resulting in a surface with lower variation (Fig. 4). Both technologies are useful; again, the choice depends on the desired end result for the surface in question. The FemoGreen can be applied for wide materials not limited to Sapphires, Glasses, Nickel, Copper, Gold, Silver, Polymers, Ceramics and more.
