The reflector decides the bundle
There are 3 ways a light bundle can be formed. A classic reflector, an lens and a modern reflector. But how do they work?
What is a classic reflector
With a classic reflector you don't much control over the light. The LED light shines directly out of the lamp, only the light from the sides gets influenced by the mirror. This produces a lot of rings in the light bundle and a clear 'hotspot' , also called centre of the light bundle. This way of reflecting is mainly used in low range bicycle lights.
What is a lens
Do you want a round light bundle? Than a lens is the perfect option to create this. The main advantage of lenses is that all the light of the LED can be controlled. It makes for an extreme clear hotspot.
What is a modern reflector
When using a modern reflector, the LED is horizontally placed, shining directly on the mirror. This way theres maximum control over the bundle. Mainly lights which are StVZO approved has to be developed in this way, because of the complex bundle that has to be produced. The main disadvantage is the loss of a lot of light when using this type of reflector.
