Title: The Innovative Contributions of Jian Tan
Introduction
Jian Tan is a notable inventor based in Beijing, China. He has made significant contributions to the field of fire alarm systems, holding a total of 3 patents. His work focuses on enhancing the efficiency and effectiveness of fire notification appliances.
Latest Patents
One of Jian Tan's latest patents involves a sophisticated fire alarm system. This system features a strobe notification appliance that includes a boost circuit connected to an input voltage, an energy storage circuit, and a drive circuit that generates a drive current. The LED circuit comprises at least one LED element, while a first sampling circuit collects the overall voltage drop of all LED elements. The control circuit is designed to adjust the drive circuit to supply a working current during an alarming stage and a detection current during a detection stage. Notably, the detection current is lower than the working current, resulting in reduced light energy during the detection stage compared to the alarming stage. This innovative approach allows the control circuit to determine the operational status of the LED circuit based on the collected voltage drop.
Another patent by Jian Tan pertains to a notification appliance within a fire fighting system. This appliance includes at least one LED, a drive circuit, and a control circuit. The control circuit outputs a flash control signal to the drive circuit in response to a selected candela setting. This signal indicates the pulse waveform characteristic and current amplitude of the drive current flowing through the LED. The design ensures that each light emission from the LED minimizes the electric energy required for the specified candela setting.
