Title: Innovations by Inventor Kelvin Shih in LED Technology
Introduction
Kelvin Shih, an accomplished inventor based in Brighton, MI, has made significant strides in the field of LED technology. With 16 patents to his name, he has developed innovative solutions that enhance the performance and efficiency of light-emitting diodes (LEDs). His work is not only pivotal for the advancement of lighting technology but also exemplifies the entrepreneurial spirit of inventors in the modern age.
Latest Patents
Among his latest inventions, one of his most notable patents is the LED junction temperature tester. This instrument measures the LED junction temperature directly, leveraging the linear relationship between the forward current through the LED, the forward voltage drop, and the junction temperature. The calibration process utilizes two LEDs from the same family at ambient temperature; by passing a small current through each, Kelvin establishes a baseline. The LED under examination is then placed in a controlled environment where the temperature is increased, and the connection between the forward drop and the junction temperature is utilized to create a self-measuring thermometer for the LED.
Another significant invention is the light-emitting diode with a thermally conductive structure. This design incorporates an anode and cathode formed from thermally conductive materials, promoting efficient heat dissipation, allowing the LED to maintain a low junction temperature even under high current conditions. This innovative structure mitigates temperature-related issues, enabling the LED to produce higher light outputs without compromising performance.
