People are using LEDs in a variety of applications, including residential lighting, aerospace, architectural lighting, automotive, aviation, broadcasting, electronic instrumentation, entertainment and gaming, and more. Especially in the micro-projection system, use of LED optics will increase over the years.
It is because lighting uniformity and efficiency on spatial light modulators or SLM are two most important factors to gauge performance of micro-projection system. People often use tapered light pipe (TLP) and square compound parabolic concentrator (SCPC) as a beam shaper in LED-based micro projection system. By this, you will get SLM with uniform and efficient illumination.
