Lighting Device Details TRIZ Cases
- refrigerator
See how a multi-layer coating with light-blocking and light-transmitting parts eliminates repet
- Refrigerator Door Out Plate with Light-Transmitting Display Holes
See how a metal out plate uses hole-filling members and layered light-blocking parts to display
- Optical Sheet Hole Layout for Uniform Surface Light Luminance
Varying through-hole diameters in selected optical sheet regions suppress concentric luminance unevenness and improve display illumination uniformity.
- Sealed Lens-Phosphor Package for Simpler Light Emission Control
Bonding the lens to the wavelength conversion member inside a sealed frame simplifies LED packaging while controlling converted light and leakage.
