Derivation and Experimental Verification of the Near-field 2D and 3D Optical Intensities From a Finite-size Light Emitting Diode (LED)

Autor: M. Nisa Khan

Publikováno v: IEEE Photonics Journal, Vol 11, Iss 6, Pp 1-19 (2019)

We derive the near-field light intensity distributions of an inorganic LED on its surface and in volumetric space. Our closed-form solution for 3D intensity distribution for a finite-size LED is consistent with Lambert's Cosine Law, which provides th

Quantification and analysis of color stability based on thermal transient behavior in white LED lamps

Autor: M. Nisa Khan

Publikováno v: Applied optics. 56(27)

We present measurement and analysis of color stability over time for two categories of white LED lamps based on their thermal management scheme, which also affects their transient lumen depreciation. We previously reported that lumen depreciation in

Minimization of lumen depreciation in LED lamps using thermal transient behavior analysis and design optimizations

Autor: M. Nisa Khan

Publikováno v: Applied optics. 55(5)

We expansively investigate thermal behaviors of various general-purpose light-emitting diode (LED) lamps and apply our measured results, validated by simulation, to establish lamp design rules for optimizing their optical and thermal properties. Thes
