Lighting Applications TRIZ Cases
- Adjustable Interior Light Lens Displacement for Beam Angle Control
Axial lens displacement adjusts beam angles in compact interior lights, eliminating bulky rotational mechanisms and reducing manufacturing complexity.
- Asymmetrical LED Reflector for Uniform Vertical Illumination
An asymmetrical reflector with inclined flat surfaces directs light from LEDs to illuminate vertical walls.
- Candle Housing with Hidden LED and Support Surface
A candle housing integrates a support surface to position a traditional candle over an internal light-emitting diode.
- Stage Light Fixture External Heat Dissipation via Support Arm Blower
A stage light fixture uses a support arm blower to circulate air around the cylindrical light head, resolving uneven heat distribution in enclosed designs.
- Window Assembly with Transparent Light Guiding Panel
A window assembly integrates a transparent light guiding panel between the glass pane and covering device to emit interior illumination.
- Watertight Luminaire Interface Using Segmented Shield and Covering
Segmented ingress protection eliminates bulky enveloping covers while maintaining 100% optical efficiency at the light-emitting aperture.
- Wearable Illumination Device Dual Light Guides Directional Color
Dual light guides with separate sources emit distinct colors in different directions for wearable illumination.
- LED Fresnel Light with Counter-Rotating Rings for Compact Transport
Counter-rotating rings adjust beam focus in a thin LED Fresnel light, reducing volume and weight for easier transport.
- LED Lighting Fixture With Integrated Heat Sink And Optical Assembly
An LED lighting fixture uses integrated heat sinks and optical assemblies to direct light upward while securely mounting modules to the fixture body.
- Luminaire Light Shield and Absorbing Coating to Prevent Spill
Shield apertures isolate modules and a light-absorbing coating on lens edges absorbs stray radiation to prevent light spill between adjacent sources.
- Spotlight Calibration via Ground Interaction Element
A spotlight calibration method uses a ground interaction element to detect illuminated region edges for mapping control values.
- Lighting Fixture Position Sensor and Calculation Unit
A lighting fixture determines movable element displacement using a position sensor and calculation unit, reducing control system complexity.
- LED Spotlight Light Mixers for Variable Beam Control
Light mixers combine different LED emission spectra to form a unified common light beam.
- Submerged LED Luminary Cooling via Radial Fins and Sealed Enclosure
Radially positioned fins channel water flow through a sealed luminary to dissipate heat from the encapsulated LED source.
- Compact Flush-Mounted Flashing Light for Aircraft Approach Guidance
A compact flush-mounted flashing light uses a short xenon lamp and integrated lens to reduce device size.
- High-Bay Luminaire Two-Piece Housing Segmentation
Two-piece housing with corrugated cover and base enables modular assembly for high-bay luminaires.
- Moving Head Light Cooling Module with Segmented Plates
A compact cooling module uses segmented plates and a centrifugal fan to dissipate heat from LEDs and circuits in moving head fixtures.
- Fresnel Lens Spiral Steps Homogeneous Lighting
Spiral steps on Fresnel lenses direct light for uniform illumination, eliminating stippling that scatters rays and reduces imaging quality.
- Radial Gobo Support Assembly for Stage Lighting Fixtures
A gobo support assembly connects to a carrier wheel via radial sliding motion and a reversible click-on locking mechanism.
- Control Unit Network Switching for Hazardous Environment Monitoring
A control unit embedded in clothing switches between cellular and non-cellular radio networks to maintain continuous data transmission.
- Multi-Angle Industrial Lamp Rotation Mechanism
Screw-driven rotation with toggle hooks locks industrial lamps at precise angles, preventing tilt during multi-angle adjustment.
- Light Head Auxiliary Heat Dissipation Air Passage
Active air convection through a dedicated heat-dissipating air passage resolves insufficient thermal management in high-power stage lights.
- Ring-Shaped Manhole Lighting System for Single-Operator Access
Battery-powered ring lighting mounts to manhole rims via magnets or screws.
- Solar-Powered Railing Lighting with Integrated Battery and Sensor
Integrated solar panel charges a battery within a railing member to power lighting devices independently of external grid connections.
- Fresnel Lens Soft Light Control for Film Production
A Fresnel optical element magnifies diffuse light to shape soft shadows on subjects.
