1. LED Tube Lamp with Dual-Pulse Installation Detection Circuit
Jiaxing Super Lighting Electric Appliance Co., Ltd., 2023
An LED tube lamp with an installation detection circuit that ensures proper connection to a lamp socket before lighting up. The detection circuit generates two pulses and sends them to a switch along with the LED driving signal. If the lamp is not properly connected during either pulse, the switch remains off, preventing the lamp from lighting. If the lamp is detected as properly connected during at least one pulse, the switch turns on, allowing the lamp to light up. This mechanism ensures the lamp only operates when fully installed, enhancing safety and reliability.
2. Lighting System with Autonomous Brightness Adjustment Using Occupancy and Ambient Light Sensors
OSRAM SYLVANIA Inc., 2022
Intelligent variable lighting systems enhance efficiency and customization by using occupancy and ambient light sensors to autonomously adjust LED brightness. These systems dim the lights when no one is present and brighten them when occupied. Adjustable transition delays optimize energy savings while avoiding abrupt lighting changes. Additionally, the systems can be remotely managed to set specific dimming levels and delays, offering greater control and flexibility.

The controller receives signals from the communication apparatus to control the LEDs and provide lighting based on detected presence or other conditions. The fixture can be easily connected to a standard light fixture socket for retrofitting buildings.
5. Lighting Fixture with Individually Controllable Discrete Light Sources and Integrated Environmental Analysis System
Yechezkal Evan Spero, 2021
Lighting fixtures use multiple discrete light sources that can be individually controlled to provide tailored lighting. The fixture has separate light sources, optics, and power control for each source, allowing precise adjustment of color, intensity, and direction. Cameras or sensors can analyze the environment or specific tasks, and software can optimize the lighting accordingly by controlling each source independently.
6. Magnetically Attachable Outdoor Solar Light with Microwave Motion Sensors and Inductive Charging
