SON edelux

Edelux is the result of consistent optimization

The basic concept of the proven and popular halogen headlamp E6 was to transform the hub dynamo power steadily and efficiently into useable light. The Edelux is the consequent development of the E6 with the potential capacitity of white high-performance LEDs. All options concerning the efficiency of LED technology, cooling and of optics have been utilized. The Edelux was designed to match the round shape of the new SONdelux but it also works with any other popular hub dynamo.

Optics

The Edelux benefits from the IQ-Tec offset reflector by Busch & Müller. In contrast to conventional headlight lenses it reflects a very high proportion of the light emitted from the LED and provides a wide and even brightly lit road. The well defined light/dark boundary at the front edge prevents glaring of oncoming cyclists. With fog, less upward scattered light causes less indirect glare for oneself. The black ring around the edge of the reflector prevents direct glare, when the headlight is mounted in your own field of vision. Precise adjustment of each LED and testing every headlamp ensure consistent quality. The anti-reflective coating glass is scratch-resistant and allows 6% more light to pass than a plastic disk.

Heat Dissipation/ Mechanics/ Electrics

Efficiency and lifetime of an LED primarily depend on their cooling. Therefore, the LED is fitted directly on a solid copper heat sink, which in turn transfers the heat to the aluminum case. At high speed, excellent cooling ensures 20% more light output than conventional LED headlights with LEDs, that sometimes produce more than 100 º C.
The entire interior of the headlamp (including switching contact) is protected by an O-ring against the ingress of moisture and dirt. Electrical contacts are soldered and sealed. The magnetic switch ring with a big nose is indestructible, doesn't rattle and allows "blind" switching even with thick gloves. With the sensor positioned switch the light turns on automatically at dusk, without being influenced by street lamps or car headlights. The robust, low-loss coaxial cable bears even rough conditions.

Electronics

Like the reflector mirror the switching regulator of Edelux also is by B & M. It prepares the electrical power of the hub dynamo with little loss for the light emitting diode. Even very fast rides do not damage the LED due to low-loss. Likewise, the voltage is limited at the switched output to not overload the rear light. A maintenance-free double-layer capacitor provides up to 4 minutes light after a stop.
