Brake Light Assembly

Subteam: ElectricalSubsystem: BSPDAssembly: Brake Light AssemblyCars: CR21, CR22, CR25, CR26I, CR26E

Purpose

Illuminate under braking as the rules require, using as little power as possible.

Function

A team-designed and manufactured PCB in a housing, mounted at the rear of the car and triggered by the brake pressure signal.

Design Process

The team has always designed and manufactured its own brake light specifically to reduce power consumption against an off-the-shelf unit. CR22's design was given to a younger member as a development project and made in the shape of a Script A.

Design Constraints

Rules define the required size, colour, brightness and position.

Manufacturing Process

Board manufactured externally, populated and bench tested in house before it goes on the car.

Full Material List

Custom PCB, LEDs, 3D printed or machined housing.

Reoccuring issues

None recorded. This part has no entry in Knowledge_Transfer/Issue Logging/Fault Vault.xlsx, in either Issue Log.xlsx, in CR22/Issue Tracking/Shakedown 7-15-23.xlsx, or in any design review issue list found in CrimsonStorage or Box.

Improvements

The Script A shape may increase power used; the plan recorded was to validate whether it saves power against the old design rather than assume.

Still to document

Nothing in CrimsonStorage covers these yet.
