Details of Lights Boards

This page goes over the details of which lights boards we have in the car and the required details for driving them.

Tjmax = 100 degrees C Look at LED lifetimes vs operating temperature - LEDs have very high lifetime, but it seems like light output decreases when temperature rises. We will chose 100C as upper limit for Tj
Tamb = 35 degrees C Max ambient temperature (car temp on hot day in desert)

We want to ensure that our Boost LED Drivers are able to drive all of the LEDs that we will be using. This table will go over the required parameters to check this. Vf is the most important parameter for this, and must be significantly higher than the input voltage of the board to ensure that accurate regulation is achieved. Check datasheet of LED driver for more specifics.

ASC Reference DRLs - Custom Dynamics TF6WC - 6 Genesis White SMD LEDs 6500K
ASC Reference BPS Strobe - same as DRLs
ASC Reference Turn - Fairly dim (1 LED would be brighter)
ASC Reference Brake - Same as turn

Cd requirements for WSC, and LEDs for each light: Very good reference that provides clear images and examples of all types of lights in the UNECE regulations: https://www.hella.com/hella-ro/assets/media_global/673_Legal_Requirements_Brochure_HELLA_EN.pdf

For some reason, the BPS strobe is also judged against the same standard for the DRLs - let’s get one in and test it.
