The DMX*LEV Lighting System
Prototyping and Development

We decided to have a little fun and do some "old school" prototyping on perforated fiberglass for this project, as we were in a bit of hurry to be able to show a prototype of the concept. The basic circuitry is not very complex, and after several days of "stitching LEDs" together, Kim had built several prototype boards.

You will see a number of cables coming from the DMX*LEV controller board, which interface to an array of handlebar switches and to the DMX*LEV light wiring chain. The handlebar switches include :

• Lights On/Off Switch
• Left/Right Turn Switch
• Brake Lever Switches
• Horn Switch
• Hi/Lo Headlight Beam Switch
• Keyswitch/Lock
• Cadence Sensor
• Wheel Sensor
• LCD Display

All of the above are useful for pedal powered vehicles, but for electric vehicles we also include :

• Cruise Control Switch
• Cruise Speed Up Switch
• Cruise Slow Down Switch
• Throttle Controller
• On/Off Road Switch

We can support up to thirty-two (32) switch or potentiometer inputs, for a wide variety of customization to your vehicle.

The initial tailight design is intended for a a three (3) wheeled, pedal-electric hybrid vehicle. Sixty-five (65) high brightness, 5mm LEDs are used. They are configured as seven (7) independently controlled strings. There are six (6) string of ten (10) LEDs each, and one center cluster string of five (5) LEDs.

We're very pleased with the way the prototype boards came out, now we can move on to the PCB layout and product packaging.
