An oxidized low density lipoprotein sensing device for a gallium nitride process is a GaN HEMT device including: a gateless AlGaN/GaN sensing transistor device, a testing window, a source, a drain, two metal connecting wires and a passivation layer. The gateless AlGaN/GaN sensing transistor device has an epitaxial wafer structure including a GaN layer and an aluminum gallium nitride layer. The testing window is disposed on the epitaxial wafer structure. The metal connecting wire is disposed on a source and a drain. The passivation layer is covered onto a surface of the sensing device except the testing window. A built-in piezoelectric field is created by the properties of FET and the polarization effect of AlGaN/GaN to achieve the effect of sensing the level of oxidizing proteins in human body quickly, accurately and easily.

摘要:
The present invention is a method for obtaining a better color rendering with a photoluminescence plate, and the better color rendering is obtained by using UV radiating on the photoluminescence plate stacked with a red photoluminescence plate, a green photoluminescence plate and a blue photoluminescence plate. Therefore, the color rendering is above 90% and close to the solar light. The photoluminescence plate can be made from directly coated with photoluminescence layers of three colors or with fully mixed fluorescent materials of three colors. Consequently, a white light relied on the present invention is more uniform than the conventional techniques with a color mixing performance based on tricolor LEDs.
