Design of compact freeform lens for application specific light-emitting diode packaging
TL;DR: A practical design method of compact freeform lens for extended sources used in ASLP was introduced and demonstrated that, comparing with traditional LED module integrated with secondary optics, the ASLP had advantages of much smaller size in volume, higher system lumen efficiency and lower cost.
Journal ArticleDOI
Phosphor self-heating in phosphor converted light emitting diode packaging
TL;DR: A thermal model of LED packaging based on phosphor particles under stair-like thermal load was built, and simulations were carried out to analyze the thermal performance of the phosphor layer as discussed by the authors.
Journal ArticleDOI
Design method of high-efficient LED headlamp lens
TL;DR: Monte Carlo ray tracing simulation results demonstrate that the LED headlamp with these two lenses can fully comply with the ECE regulation without any other lens or reflector.
Journal ArticleDOI
Freeform LED lens for rectangularly prescribed illumination
TL;DR: In this article, a modified discontinuous freeform lens design method was presented for rectangularly prescribed illumination, with the advantages of a flexible energy mapping relationship, accurate light irradiation control and easier to manufacture.
Journal ArticleDOI
Analysis of condition for uniform lighting generated by array of light emitting diodes with large view angle
TL;DR: Analysis and simulation results showed that the method for uniform lighting generated by array of LEDs with large view angle is available for LED array lighting system design on the basis of largeView angle LED.
