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.
- Switchable Light Controller for Privacy Beam Direction
A switchable light controller collimates or diffuses emitted light to improve privacy, visibility, and driver distraction control.
- Light-Shielding Aperture Layer for Hidden Color-Changing Icons
A patterned light-shielding layer with a controlled aperture ratio hides icons when idle and enables real-time color changes at lower manufacturing cost.
- Backlit Icon Cover Plate With Aperture-Controlled Light Shielding
Micro-openings in a light-shielding icon area let backlit symbols disappear or change color in real time while avoiding complex printed icon processes.
- Backlight Lens Design for Uniform Light Distribution
An aspheric secondary lens redistributes light from fewer sources to eliminate hot-spots and maintain uniform brightness across the panel.
- Offset Aim Line Units for Barcode Scanner Parallax Reduction
Offset aim line units project intersecting bounded light patterns to indicate the field of view center in imaging devices.
