Light at close range - Sensor-controlled - Standlight
Light at close range
For a secure ride, it is important to be able to see the road directly in front of the bicycle. Bumps or potholes in the road can be seen better if this area is lit, and can be circumnavigated by short and intuitive steering. During darkness, this is only possible if the area between one and four metres in front of the bicycle is lit brightly and homogenously. Subjectively, the need for light at close range is higher the slower one is riding, because one’s balance can more easily be influenced by obstacles.
“With light at close range” means that the light field emitted by our headlights starts directly one metre in front of the bicycle.
This innovation presented by Busch + Müller in the nineties has become a safety standard. The affix “plus” means that the product is equipped with standlight. For this function, no batteries are necessary. It works this way: As soon as the bicycle stops, the standlight is powered by a maintenance-free capacitor. This capacitor is charged during the ride.
By the way: The standlight of a LUMOTEC headlight can shine for several minutes. Therefore, the standlight of many IQ headlights can be deactivated manually – so as not to attract thieves to a parked bicycle.
„Sensor automatic“ usually means that the headlight activates automatically when cycling during dusk or darkness and switches off when subjected to daylight. Continuous energy supply by a hub dynamo is required for this function. In order for the headlight to not mistakenly react to car headlights, the sensor functions with a time delay.
In headlights equipped with daytime running light, the sensor automatically switches between day and night mode.
