Non-Electric Lighting TRIZ Cases

Grooved optically-transparent cover directs light emission angles to increase transmittance through the sealing interface.

A hybrid projector optical system collects light from an LED source using integrated reflector and lens elements to shape the beam pattern.

Sequential actuation with time delays reduces electromagnetic interference while maintaining simultaneous activation across military aircraft.

Segmented lens regions redirect light via total internal reflection to widen transmission angles, reducing LED count for uniform backlighting.

Distinct convex and concave surface curvatures in a backlight lens refract light to prevent leakage and reduce LED element count.

An angled supporter inside a concave reflector redirects LED light to reduce dazzling effects while maintaining high output intensity.

A hollow post body formed from fiber plates with V-shaped grooves and embedded connectors replaces solid wood in light fittings.

Segmented lampshade inserts enable tool-free design changes, reducing storage costs.

Rotating the filter wheel about two axes adjusts bandpass frequencies and reflects white light, eliminating multiple light sources.

A MEMS illumination mitigating mechanism employs collimators and absorbing layers to block stray light, reducing parasitic signals on peripheral electronics.

A vehicle lighting device uses a 3D screen to transmit light from multiple sources for enhanced aesthetic appeal.

An intermediary reflector redirects LED light through a perforated heat sink, reducing hot spots while enhancing thermal management.

Segmenting the cover into an inner dust barrier and outer translucent layer prevents unsightly black spots on illuminated canvases.

A diagnostic probe penetrates LED light string insulation to contact conductors and apply controlled electrical waveforms for component testing.
