Light-emitting diodes (LEDs) are considered an ideal substitute for low-efficiency traditional
light sources with broad applications in all scientific disciplines. For the past recent years …

Laser-driven white lighting sources have great potential for applications with super-high
brightness, high directionality and long distance illumination, but are usually limited by their …

In this study, a model for calculating the bidirectional scattering properties of phosphor layer
was established by considering the light absorption and light conversion of phosphor …

High angular color uniformity (ACU) is strongly required in many illumination applications. In
this study, we presented the phosphor dip-transfer coating method to realize high ACU for …

Nitride light-emitting diodes (LEDs), from nitride chips to devices, must be packaged. The
chip packaging processes have an important role in determining the final optical and …

Angular color uniformity (ACU) is one of the most important optical parameters of white
lighting emitting diodes (LEDs). In this paper, we proposed a kind of phosphor coating …

State of the art fabrication of LED modules based on chip-on-board (COB) technology
comprises some shortcomings both with respect to the manufacturing process itself but also …

We demonstrate a new kind of substrate structure to enhance the correlated color
temperature (CCT) consistency of white light-emitting diodes through controlling the liquid …

Low cost and high performance are the pursuing goals of the light-emitting diode (LED)
packaging. The phosphor layer configuration of LEDs significantly influences optical …

A near-infrared optical tomography approach for detection, three-dimensional localization,
and cross-section imaging of fluorescent targets in a turbid medium is introduced. The …
