Nested Serial Network Configuration for Array of Serially Connected Light Heads
8 Jul 20
An array (166, 184, 194, 230, 256) of multiple light heads (170, 186, 194, 236) for a vehicle (100) has a primary Controller Area Network (CAN) serial data bus (108, 224) to carry first serial communications among spaced-apart CAN nodes (112, 118, 130, 136, 140, 154, 220, 260, 288) communicatively coupled thereto.

Low-dropout Current Regulator for Light Head
27 Nov 19
In connection with a ground transportation vehicle light head (86) powered by a battery-based voltage source (20) supplying positive (76) and reference (i.e., ground) (78) voltages that define a voltage difference (22) applied across a number of multiple series-connected high-power light-emitting diodes (HP LEDs) (12) and current regulator circuitry (80) electrically connected to them, ultra-low dropout circuit techniques are disclosed for increasing a portion of the voltage difference available from the battery-based voltage source to forward bias and thereby maximize the number of the multiple series-connected HP LEDs emitting light by maintaining a low voltage drop (82) across the current regulator circuitry.
