Lighting Circuits TRIZ Cases
- Vehicle Interior Lighting Adaptation Based on Occupant Viewing Location
An image sensor detects occupant gaze direction to dynamically adjust vehicle interior light intensity for optimal visibility.
- Adaptive Emergency Exit Lighting for Vehicle Rollover
Sensors detect rollover or immersion to trigger asymmetric LED illumination, guiding occupants during extreme vehicle displacement.
- Wireless Doorsill Plate Power Management and Dynamic Display
An energy-saving module reduces electric power consumption by controlling the backlight unit, resolving battery load issues in wireless doorsill plates.
- Capacitive Proximity Sensor for Sealed Automotive Lamp Switching
Replacing mechanical switches with a capacitive proximity sensor eliminates openings that allow liquids and debris into the lamp enclosure.
- Vehicle Terminal Lighting Synchronization via Illuminance Mapping
Illuminance mapping table synchronizes terminal brightness with vehicle interior lighting to reduce driver eye strain.
- Selective Power Supply for Incandescent and LED Lighting
A power supply device reconfigures a supply transistor into ohmic, PWM, or saturated regimes based on detected lighting module structure.
- Sun Visor Connector With Preliminary Displacement Portion
A sun visor connector uses a preliminary displacement portion to maintain separated arm connection parts.
- Motor Vehicle Interior Trim Light Transmittance
Translucent vehicle trim illuminates storage compartments through a 5-10% light transmittance cover while protecting the rear-mounted light source.
- Car Lamp Music-Synchronized Control via Beat Detection
A car lamp control method extracts musical-composition information to drive light emitting regions and time periods for synchronized visual effects.
- Proximity Switch Groove and Pliable Overlay for False Activation
Grooves between adjacent sensors prevent field interference while pliable overlays enable virtual button modes to stop accidental activations.
