With Built-In Power TRIZ Cases
- Short-Circuit Protection Circuit With Thyristor-Latched Switch Cutoff
A thyristor-latched control circuit keeps the switch transistor fully off during a short circuit, improving protection reliability in lighting power supplies.
- LED Downlight Power Circuit for Battery Expiry Alarm Control
A microcontroller monitors emergency battery service life and triggers alarms or intermittent LED operation before backup power fails.
- Photovoltaic Lamp Glass Cover Packaging With UV Adhesive Curing
UV-cured glass cover packaging replaces epoxy lamination in a photovoltaic lamp, improving transmittance, output stability, and service life.
- UV-Pulsed Emergency Lighting With Fluorescent Exit Indicators
Pulsed UV sources excite fluorescent indicators to maintain emergency visibility while conserving battery power and extending runtime.
- Egress Light Self-Testing Module for Remote Power Disconnect Detection
Locally powered testing and alerting detects egress light power disconnects and component failures before backup lighting is needed.
- Emergency LED Lighting Module With PWM Battery-Saving Dimming
PWM dimming lowers LED brightness during outages so emergency luminaires meet required runtime with smaller batteries and lower power draw.
- Emergency Luminaire Two-Line Power Switching for Slim Installations
A two-line converter switches between mains and battery power so emergency and non-emergency luminaires work with less wiring and slimmer mounting.
- PoE Lighting Driver Link-Loss Emergency Power Switching
Physical link-loss detection in a PoE lighting driver triggers immediate emergency illumination and logs luminaire power use after recovery.
- Emergency Lighting Converter Log Access via Shared Interface Pins
Shared test-switch and indicator interfaces expose converter log data externally, avoiding housing disassembly and extra connectors.
- Emergency Lighting Converter Interface Using Switch Pins for Log Readout
Reusing test switch and indicator connections enables external log readout from an emergency lighting converter without opening the housing.
- Hinged Back-Lit Signage With Solar Charging And LED Panels
Solar charging powers removable LED panels behind graphic signs, while hinged frames support durable, fast outdoor content changes.
- Emergency LED Driver Terminal Reduction via Merged Switch and Indicator Circuit
A microprocessor detects test switch actuation and battery duration selection using a single input terminal through a divider network.
- Photoelectric Device With Integrated Optical Chamber
A photoelectric device assembles multiple plates into a chamber with embedded light sources to amplify optical energy.
- Emergency Luminaire Light Guide Bar Thermal Decoupling
A light guide bar redirects LED emission through total internal reflection to enable independent component positioning.
- Solar Panel Module Design for Outdoor Mosquito Killer Lamp
A solar panel module converts sunlight into stored electrical energy to power LED and high-voltage grid components in outdoor environments.
