Using Color to Enhance LED Lighting Quality

Type of Resource



Students take what they know about materials, optical properties and electrons to the next level—to see how semiconductors can be used to augment light. First, they learn how light-emitting diodes (LEDs) work, which helps them to think critically about a real-world problem they are asked to solve later in the activity as if they are practicing engineers. The challenge: To design an improved LED headlight that lights the roadway without distracting oncoming drivers and passengers with the harsh,
