Title: The Innovative Contributions of Seth Chang
Introduction
Seth Chang is a prominent inventor based in Rowland Heights, California. He has made significant contributions to the field of lighting technology, holding a total of nine patents. His work focuses on creating efficient and innovative lighting solutions that enhance both functionality and design.
Latest Patents
One of Seth Chang's latest patents is for a recessed LED light fixture without a secondary heat sink. This innovative design eliminates the need for a bulky, finned, metal heat sink. The recessed LED light fixture features a Metal Core Printed Circuit Board (MCPCB) that holds an array of LEDs arranged at the center. The LEDs are mounted to the printed circuit board using patterns of electrical and greases that conduct current and radiate heat. A mounting bracket holds the entire assembly together while spacing the LED driver and printed circuit board apart for further cooling. The upper side of the printed circuit board is exposed to the ambient air inside the housing, enhancing heat dissipation.
Another notable patent is for an LED light module assembly for a light fixture. This assembly includes a light source with a printed circuit board containing an LED driver and LEDs. The printed circuit board is directly attached to a mounting plate made of thermally conductive and radiating material. An LED cover overlies the LEDs, while spring retainer clips hold a decorative trim ring in a spaced-apart relationship from the mounting plate, creating an air gap for cooling. Additionally, a light diffuser lens with hooked legs twist locks to the mounting plate, diffusing the light from the LEDs effectively.
