| 20110273107 | SOLID-STATE LIGHTING OF A WHITE LIGHT WITH TUNABLE COLOR TEMPERATURES - A light-emitting diode (LED)-based solid-state device comprises a color mixing mechanism to dynamically change the correlated color temperature (CCT) of a white light. With different lumen proportions for white phosphor-coated LEDs and integrated red and green LEDs, the light mixtures can be located in any one of eight CCT quadrangles. In practice, CCTs of a white-light can be tuned in a continuous manner. Because all the possible light mixtures on the chromaticity diagram correspond to a line segment that overlays the Planckian locus within the eight CCT tolerance quadrangles, the effect of LED intensity fluctuations that may put the mixture out of white light region is reduced. Also, because the two additional LEDs that mix with the white phosphor-coated LEDs contribute to the overall spectral power distribution (SPD) that substantially matches the SPD of standard illuminants, a CRI of 80 can be reached. | 11-10-2011 |
| 20110176297 | LINEAR SOLID-STATE LIGHTING WITH BROAD VIEWING ANGLE - A linear light-emitting diode (LED)-based solid-state device comprising a curved surface to hold a flexible printed circuit board with multiple linear arrays of surface mount LEDs provides lighting applications with a broad viewing angle over 180° along the radial direction. On each of the two lamp bases of the lamp, a shock-protection switch is mounted to prevent shock hazard during re-lamping. | 07-21-2011 |
| 20110149564 | LINEAR SOLID-STATE LIGHTING WITH A DOUBLE SAFETY MECHANISM FREE OF SHOCK HAZARD - A linear light-emitting diode (LED)-based solid-state lamp having a double safety mechanism that comprises at least three shock protection switches, fully protects a person from possible electric shock during re-lamping or maintenance. One protection switch provided at each end of the lamp is able to cut off power when the associated end of the lamp is not inserted into the lamp socket. A third protection switch can be used to turn off the power from the AC main for additional shock protection. | 06-23-2011 |
| 20110149563 | LINEAR SOLID-STATE LIGHTING WITH SHOCK PROTECTION SWITCHES - A linear light-emitting diode (LED)-based solid-state device comprising at least two shock protection switches, at least one each at the two ends of the device, fully protects a person from possible electric shock during re-lamping with LED lamps. | 06-23-2011 |
| 20100290744 | ADAPTIVE DEVICE FOR SHIFTING IMAGING AXIS ACROSS FIBER-OPTIC ENDFACES IN MULTI-FIBER CONNECTOR FOR INSPECTION - A device for shifting the imaging axis of a microscope across the endfaces of a multi-fiber connector for inspecting the endfaces comprises: a supporting body attached to the optical tube of a microscope and having an extended portion; a swinging lever mounted at one end to the extended portion of the supporting body and rotatable on an axis perpendicular to the imaging axis of the microscope; a connection piece connecting between the swinging lever and a fitting tip; a bevel wheel fastened to the supporting body; and a torsion spring for pushing the swinging lever against a slanted surface of the bevel wheel. The bevel wheel is adapted to swing the swinging lever relative to the supporting body so that the imaging axis of the microscope is moved relative to the fitting tip to selectively align the imaging axis across the endfaces for inspection. | 11-18-2010 |
