What are projector headlamps and how do they work?
Projector headlamps are a type of automotive headlight that uses a projector lens to focus and direct light onto the road. They work by using a high-intensity discharge (HID) or light-emitting diode (LED) light source, which is then reflected off a mirror and focused through a lens to create a concentrated beam of light. This beam is then directed onto the road, providing a clear and focused source of illumination.
The projector lens is designed to control the light output and create a sharp cutoff point, which helps to prevent glare and improve visibility. The lens is typically made of a high-quality glass or plastic material and is designed to withstand the rigors of the road. By using a projector lens, projector headlamps are able to provide a more focused and controlled source of light, which can improve visibility and safety on the road.
