Electrical Apparatus TRIZ Cases

Operating circuit segments LED strings to control color temperature via dynamic current distribution, preventing thermal energy conversion during dimming.

A multi-tap capacitor adjusts ballast circuit capacitance to control lumen output, reducing warm-up time and re-ignition delays.

Centralized 48V DC distribution eliminates high-voltage AC safety risks and multiple conversion stages, reducing system complexity and energy losses.

A light-emitting element uses a single layer of quantum dots with transition metal oxide shells to emit red, green, and blue light.

A three-wire four-way LED lamp string connects adjacent lamps via specific wire patterns to enable customizable spacing.

A UV sterilization device uses an occupancy detector and controller to emit radiation only when a room is empty.

A liquid crystal light distribution part adjusts the emission area of an illumination device based on time information.

A DC-DC converter and control unit system adjusts switching duty cycles to regulate driving current across multiple LED arrays.

Tapered insulating layers protect electroluminescent structures, resolving positioning errors and boosting manufacturing yield.

Boron-nitrogen heterocyclic compounds improve luminosity and reduce driving voltage by facilitating thermally activated delayed fluorescence.

Distinct fused ring structures in a mixed powder stabilize vaporization rates, maintaining consistent mixing proportions to reduce film defects.
