20110038146	TUBULAR LED LIGHTING DEVICE - A tube elementary LED includes an elementary glass tube through which light can be transmitted and includes two sealed ends respectively provided with a power plug and a power socket and a LED light emitting base plate disposed in the tube that is powered by the power plug and the power socket. A plurality of LED chips for emitting light are mounted on one surface of the LED light emitting base plate and supports fix the LED light emitting base plates in the chamber of the elementary glass tube. The tube elementary LED may include a reflector attached on an internal surface or an external surface of the elementary glass tube to reflect the light emitted from the LED light emitting base plate to outside of the elementary glass tube.	02-17-2011
20110031869	COMPOUND HID ELECTRIC ARC TUBE - A composite High Intensity Discharge (“HID”) arc tube includes a discharge tube and two outwardly extending tubes. The discharge tube is a composite two-layer shell with an outer of fused quartz glass or Vycor quartz glass, and a layer of translucent polycrystalline alumina (“PCA”). The outwardly extending tubes are made of fused quartz glass or Vycor quartz glass, and a layer of polycrystalline alumina is applied at ends of the outwardly extending tubes close to an arc chamber. After the arc tube is sintered at a high temperature, the electrode is sealed by being separated into two segments. The first segment of the outward extending tube applied with PCA is sealed by glass solders, and the second segment of quartz glass is sealed by a molybdenum foil under pressure.	02-10-2011
