“COB” stands for “Chip on Board”. “Chip” here means the small LED (light-emitting diode). This is applied directly to the “board” (see PCB – Printed circuit board) together with a few more LEDs. In the case of the Micro Lens COB, for example, there are 40 of them. This technology enables a modern light pattern design for rear lights.




LED – “Light emitting diode”. It has now completely replaced the incandescent bulb. The advantages of the LED over the incandescent bulb are a much longer lifetime and robustness in the event of shocks. And all this at only about one tenth of the energy consumption.




PCB – “Printed circuit board” is a carrier of electronic components, such as capacitors, resistors, sensors and also LEDs. It is found in virtually every electronic device, including our bicycle lights. In dynamo front lights, for example, the capacitors for the stand light function are found on the PCB. In the case of rear lights, the sensor for the StopTech brake light function is located there, for example, as in our “Edge” brake light.
