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.
Board | LED Color | LED count | Total Vf | Worst Case Power Dissipation | Max Thermal Resistance to Ambient | ||||
|---|---|---|---|---|---|---|---|---|---|
Daytime Running Lights | White | 6 (not finalized) | 6 x 2.9 = 17.4V | 17.4V x 0.35A = 6.09W | |||||
Side Turn Indicators | Amber | ||||||||
Rear Brake | (50 - 35) / 6.09W = 2.4 | Side Turn Indicators | Amber | Rear Brake | RedRed | 6 (not finalized) | 6 x 2.2 = 13.2V | 13.2 x 0.35A = 4.62W (Current may have to be increased) | (50 - 35) / 4.62W = 3.24 C/W |
