Semiconductor Devices For Light Sources TRIZ Cases
- LED Light Source Package With Segmented Phosphor Carrier
Segmented phosphor patterns on a transparent carrier wrap LED chips to resolve non-uniform distribution and degradation issues in COB packaging.
- Grid Lamp 2D Reflector Cell Array LED Positioning
Offsetting LEDs within reflector cell neck openings smooths the light distribution pattern while reducing sensitivity to manufacturing tolerances.
- LED Air Ring Optical Structure for Yellow Ring Effect
A wavelength-converting layer and surrounding air ring structure eliminate the yellow ring effect in light-emitting devices.
- Segmented LED Arrays with Diffusing Elements for Uniform Illumination
Diffusing elements blur patterning in segmented LED arrays, approximating a diffuse extended light source and reducing discernible patterns.
