Patent number: 7938557Abstract: A light source and a method for operating the same are disclosed. The light source includes a light emitter and a controller. The light emitter generates light in response to a control signal coupled thereto. The light emitter is characterized by an age related to the amount of light that has been cumulatively generated by the light emitter, the generated light for a given control signal changing with the age. The controller measures the age of the light emitter and generates the control signal based on the desired light intensity and the measured age of the light emitter. In one embodiment, the controller stores an age value for the light emitter, and the controller determines the control signal in response to an input signal specifying a desired light intensity from the light emitter, the controller updating the age value each time the control signal is determined.Type: GrantFiled: December 23, 2004Date of Patent: May 10, 2011Assignee: Avago Technologies ECBU IP (Singapore) Pte.

Publication number: 20090122515Abstract: Light is emitted from a light emitting device. The light emitted from the light emitting device is combined with light from a first type of phosphor and a second type of phosphor. The first type of phosphor and the second type of phosphor are within an epoxy placed over the light emitting device. The first type of phosphor, when excited, emits light of a first color. The second type of phosphor, when excited, emits light of a second color. The first color and the second color are different.Type: ApplicationFiled: January 4, 2009Publication date: May 14, 2009Inventors: Su Lin Oon, Janet Bee Yin Chua

Patent number: 7208738Abstract: A light source is disclosed. The light source has a light-emitting chip that includes an LED that generates light in an active region thereof. The LED emits a light signal in a forward direction, and infrared radiation generated in the active region is emitted in a side direction in the form of a first infrared signal. The first light signal is determined by a first drive signal coupled to the LED. The light source also includes an infrared detector positioned to collect a portion of the infrared signal. The infrared detector generates a heat signal indicative of the amount of infrared radiation detected. A controller generates the drive signal so as to maintain the heat signal at a first target value. In light sources having LEDs that emit in different spectral ranges, the infrared detectors can all detect heat in the same spectral range.Type: GrantFiled: February 28, 2005Date of Patent: April 24, 2007Inventors: Sundar Natarajan Yoganandan, Fakhrul Arifin Mohd.

Each of the at least one fiber optic light guide has a first end that is independently positionable with respect to the solid-state light emitter(s) to receive the light emitted by the solid-state light emitter(s). Each photosensor is positioned to receive light emitted from a second end of one of the light guides. The control system is operably associated with the solid-state light emitter(s) and the photosensor(s) to regulate the light output of the light emitter(s) in accordance with measurements received from the photosensor(s).Type: ApplicationFiled: October 29, 2004Publication date: May 4, 2006Inventors: Kian Shin Lee, Thye Linn Mok, Kheng Leng Tan, Fakhrul Arifin Mohd Afif, Siew It Pang, Yew Cheong Kuan, Norfidathul Aizar Abdul Karim, Su Lin Oon, Wen Ya Ou, Sundar A/L Natarajan Yoganandan

Patent number: 6806658Abstract: A LED that includes a light emitter that emits light of a first wavelength and a phosphor layer that converts a portion of that light to light of a second wavelength is disclosed. The phosphor layer includes a powdered phosphor suspended in a photo-curable medium that sets upon exposure to light of a curing wavelength. The phosphor layer can also include a thixotropic agent that reduces the rate at which the powdered phosphor settles in the medium prior to the medium being exposed to light of the curing wavelength. The photo-curable medium preferably includes a photo-curable epoxy that cures in a time that is short compared to the settling time of the phosphor powder in the medium.Type: GrantFiled: March 7, 2003Date of Patent: October 19, 2004Assignee: Agilent Technologies, Inc.Inventors: Kheng Leng Tan, Abdul Karim Aizar, Su Lin Oon, Boon Chun Tan
