Illuminated Signs TRIZ Cases

A bent plate backlight module positions light sources in opposing grooves to create dual plane illumination.

Cavity-based pad support stabilizes LCD light guide plates, preventing component separation and friction damage from vibration.

A spectrum-expanded road electric sign integrates visible and infrared LED arrays on a single substrate to transmit traffic data.

A fixing member secures an optical film assembly to a frame using a reflective sheet protrusion.

Integrated circuit contacts on the light guide plate eliminate separate boards, resolving fabrication complexity while ensuring uniform illumination.

Opaque bead blocks light passage in decorative motif support framework, reducing electrical energy consumption and light pollution.

Segmented housing units adapt to varying panel sizes, eliminating custom mold development costs.

Segmented sign posts with universal connectors resist vandalism and weather damage while supporting dynamic sign configurations.

Gradient LED holes in a resin reflection sheet accommodate thermal displacement to prevent diode hiding and maintain backlight luminance.

Segmented back slices slide out of the frame to replace damaged LEDs without disassembling the entire unit.

Segmented rotatable displays use gravity to correct inverted text and logos on rotating concrete mixer drums.

Integrating a circuit on the light guide plate eliminates separate board assembly, resolving nonuniform illumination in large area modules.

Segmented top covers rotate to align contactless logos while nested cable channels reduce thickness and prevent unauthorized access.

A backlight unit positions higher brightness light sources near the center and lower brightness sources at the periphery to improve illumination.

One-piece injection molded base housing modular LED arrays and control boards for illuminated jackpot signage.

Dumbbell-shaped long holes in backlight optical sheets distribute stress from protrusions, preventing cracking during external impacts.

Integral aluminum fins and corner waterproof blocks manage heat dissipation while preventing rainwater permeation through welding joints.

Stoppers and positioning holes align the mold frame with the body, reducing assembly time and improving yield.

A backlight assembly uses a reflecting plate with penetration holes to transmit and reflect light from parallel lamps.

A flexible reflection tape blocks light leakage between the light guide plate and cover bottom, converting harmful gaps into useful brightness for LCD devices.

Thickness-patterned diffuser plates with transparent supports prevent self-weight bending and eliminate light leakage from spacers.
