Types of Reflection

Light as it hits an object:

• Light interacts with a part in several ways


• Conservation of energy principal:  energy changes in form, but the total amount remains constant


• Understanding how reflection occurs helps to control "hot spots" and achieve even illumination

Types of reflection:

1. Specular:  Smooth surfaces direct reflected light at opposite angle


2. Diffused:  Rough surfaces scatter light in all directions


3. Spread:  Some surfaces have a combination texture and smooth surface
