Publication number: 20090014733Abstract: The present invention relates to a light-emitting diode (LED) module (10) comprising a first LED chip (12) for emitting light of a first color, a LED element (14) comprising a second LED chip, which element is placed alongside the first LED chip and adapted to emit light of a second color, and a ceramic conversion plate (16). The ceramic conversion plate covers only a portion of the first LED chip and comprises a wavelength-converting material for converting light emitted from the first LED chip to a third wavelength. The size of the portion of the first LED chip that is covered by the ceramic conversion plate is selected so that the LED module produces mixed light of a certain desired color The present invention also relates to a method of manufacturing such a LED module.Type: ApplicationFiled: February 27, 2007Publication date: January 15, 2009Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Aldegonda Lucia Weijers, Martijn Henri Richard Lankhorst, Lingli Wang, Teunis Willem Tukker

Patent number: 7307267Abstract: The electric device (1, 100) has a body (2, 102) having a resistor (7, 107) comprising a phase change material being changeable between a first phase and a second phase. The resistor (7, 107) has a first electrical resistance when the phase change material is in the first phase and a second electrical resistance, different from the first electrical resistance, when the phase change material is in the second phase. The body (2, 102) further has a heating element (6, 106) being able to conduct a current for enabling a transition from the first phase to the second phase. The heating element (6, 106) is arranged in parallel with the resistor (7, 107).Type: GrantFiled: December 5, 2003Date of Patent: December 11, 2007Assignee: NXP B.V.Inventors: Martijn Henri Richard Lankhorst, Erwin Rinaldo Meinders, Robertus Adrianus Maria Wolters, Franciscus Petrus Widdershoven

Patent number: 7291505Abstract: The invention relates to a ferroelectric device (10) with a body (11) comprising a substrate (1) and a ferroelectric layer (2) provided with a connection conductor (3) on a side facing away from the substrate (1), which ferroelectric layer contains an oxygen-free ferroelectric material (2) and is used to form an active electrical element (4), in particular a memory element (4). Such a device forms an attractive non-volatile memory device. In accordance with the invention, a conductive layer (5) is present between the substrate (1) and the ferroelectric layer (2), which conductive layer forms a further connection conductor (5) of the ferroelectric layer (2), and the active electrical element (4) is obtained as a result of the fact that the ferroelectric layer (2) forms a Schottky junction with at least one of the connection conductors (3, 5).Type: GrantFiled: July 10, 2003Date of Patent: November 6, 2007Assignee: NXP B.V.Inventors: Paul Van Der Sluis, Martijn Henri Richard Lankhorst, Ronald Martin Wolf

Patent number: 7119353Abstract: The electric device (100) has a body (102) having a resistor (107) comprising a phase change material being changeable between a first phase and a second phase. The resistor (107) has a first electrical resistance when the phase change material is in the first phase, and a second electrical resistance, different from the first electrical resistance, when the phase change material is in the second phase. The phase change material constitutes a conductive path between a first contact area and a second contact area. A cross-section of the conductive path is smaller than the first contact area and the second contact area. The body (102) may further have a heating element 106 being able to conduct a current for enabling a transition from the first phase to the second phase. The heating element (106) is preferably arranged in parallel with the resistor (107).Type: GrantFiled: December 5, 2003Date of Patent: October 10, 2006Assignee: Koninklijke Phillips Electronics N.V.Inventors: Martijn Henri Richard Lankhorst, Franciscus Petrus Widdershoven, Robertus Adrianus Maria Wolters, Wilhelmus Sebastianus Marcus Maria Ketelaars, Erwin Rinaldo Meinders
