Abstract
The present disclosure provides an illumination structure and a light distributing method. The illumination structure includes a substrate, a first light emitting element, a second light emitting element, a reflection housing and a hooding board. The reflection housing has a first focal point and a second focal point. The first light emitting element is disposed on the substrate and located at the first focal point of the reflection housing. The second focal point is positioned within the hooding board. Therefore, a portion of light emitted by the first light emitting element will be reflected by the reflection housing and pass through a hollow portion of the hooding board to generate low beam light.
