Design Considerations

Try to maximize the amount of design re-use between all the various lighting locations. This includes maintaining similar construction techniques, PCB designs, LED spacing/pitch, etc. in order to make our lives easier.

Dimension

LED Pitch

  • Constant for all light elements

  • A spacing of ~8 mm between each LED should help to facilitate better diffusion/minimize LED “hotspots” (https://www.waveformlighting.com/led-strip-lights)

  • High Density LED strips use 120 LEDs per meter (8.3 mm pitch)

  • Medium Density use 72 LEDs per meter (13.9 mm pitch)

  • Low Density use 30 LEDs per meter (33.3 mm pitch)

PCB Length

  • Determined by desired light element length (number of LEDs), LED pitch, heat sync length requirements, and mounting hole locations

  • Constrained by amount of available space on either side of the light element

PCB Width

  • Determined by width requirements for heat sync and/or connector

  • Constrained by amount of available space above/below the light element

PCB Depth

  • Determined by depth requirements for heat sync and/or connector

  • Constrained by available space behind the light element

Form Factor Concepting

Headlights (DRL and Front Turn Signals)

The headlights consist of 3 individual lighting elements (with their own respective PCB’sPCBs):

  1. Inner DRL (located closer to center of car)

  2. Outer DRL (located closer to outside of car)

  3. Front Turn Signal

Two DRL elements/PCB’s PCBs are used as a result of having to fit to the curvature of the headlight while ensuring that the combined size of both DRL elements are large enough to be visible and aesthetically pleasing. It is proposed that the two DRL elements could be controlled individually for flashy sequential headlight start-up sequences.
