A disposable aroma capsule and heat-conduction holder simplify lamp assembly, avoid shadowed lighting, and cut refill cleaning time.

A smooth cylindrical substrate, retainer caps, and a domed reflector deliver even backlighting while keeping the film image removable.

Segmented arc sections and an X-shaped support cut storage volume for a flagpole light-strand tree while preserving conical stability.

A modular solar LED unit inside the mailbox post removes AC wiring, cuts maintenance, and keeps address indicia visible in bad weather.

A flexible silicone surround with embedded plant materials diffuses and filters light while improving durability, touch, and bulb protection.

Spaced white LED panels on flexible arms reduce shadows and overillumination while improving facial lighting for video communication.

A thickened central mount and rising heat-dissipating ribs move LED heat to the sidewalls, preventing overheating in refrigerated spaces.

Spaced attachment points on an elongated member create overlapping surface elements that hide fasteners and simplify large-area assembly.

A condensing lens and lens hood improve headlamp ambient-light sensing by blocking beam crosstalk and simplifying assembly.

Coherent through-holes in a masked carrier and cover layer hide light sources off-state while keeping emitted light uniform in color.

A condensing lens in a portable power supply focuses LED light into a small beam, extending illumination distance for clearer outdoor use.

Flexible LED filaments tied or woven into 3D structures improve spatial light distribution, local brightness, and bulb-like aesthetics.

A detachable shoulder strap and handle system makes portable energy storage easier to carry for longer periods with less arm strain.

An integrated light-shielding sheet and light concentrating portion forms the low beam cutoff and Region III beam while reducing lamp space and weight.

Rotating connecting sleeves let the lamp holder fold into a compact form for transport and storage while preserving frame firmness.

A tilting projector mount inside a shaded lamp redirects projection light without mirrors, keeping the illumination unit compact and less visible.

Smoothly shifting UV and white light intensity reduces eye strain during fluorescent workpiece surface inspection.

Insulation sleeves or pads isolate spring clips from the metal member, preventing ghost light while keeping lamp mounting simple.

By routing wiring outside plenum space, this window shade pocket cuts cable cost while adding exterior lighting and automated security response.

Magnetic ceiling and frame coupling lets a decorative cover update light fixtures without touching the fixture or requiring laborious installation.

A movable light-transmitting member shifts against an anti-glare portion to balance glare reduction, light intensity, and luminous angle.

A motor-driven refraction sheet and laser lamp turn a torchiere from single illumination into dynamic ambient lighting with richer color effects.

Thermally deformed connecting plates join the lamp housing and lampshade directly, removing the hidden frame and uncertain glue bond.

A stimulus-responsive coating lets one lampshade switch light colors without replacing shades or bulbs, cutting change time and cost.

A PCB opening lets a UV-B LED die share an indoor white-light module, supporting vitamin D production with lower package cost.

A clamped outer cover keeps rain and debris off the bulb while allowing secure rotation-based assembly and quick disassembly.

Sensors, wireless control, and auto-extinguishment make a natural-flame candle safer to place and operate without losing its visual appeal.

Segmented meshed walls in a 3D printed luminaire fixture relieve cooling stress, reducing warpage and delamination while preserving strength.

A flexible hollow fastener and detachable support bracket simplify lampshade assembly while improving connection stability and storage efficiency.
