Elongate Light Sources TRIZ Cases
- Ballast-Bypass LED Tube Lamp With Foreign Impedance Detection
A ballast-bypass LED tube lamp uses a control circuit to detect foreign external impedance on its power supply module.
- Intersecting Surface Reflector for Uniform LED Lighting
An intersecting surface reflector redirects light from spaced LEDs to resolve shadow effects and maintain optical efficiency.
- LED Bulb Filament Adhesion and Helium Cooling
An adhering layer secures a flexible LED filament to a translucent envelope inner surface while helium gas enhances heat dissipation.
- Slim Luminaire With Replaceable LED Modules And Light Redirecting Lens
Segmented LED modules and a light redirecting lens resolve the contradiction between slim height and uniform glare-free illumination.
- Coextruded Luminaire Element for Reflector and Diffuser Integration
A coextruded lighting element merges reflector and diffuser functions into a single profile.
