Patent number: 8536784Abstract: The inventors have anticipated that there is no problem in employing electron gun deposition as a method of forming a metallic layer on an EL layer of an active matrix light-emitting device because the TFT of the active matrix light-emitting device is disposed below the EL layer.

Patent number: 8536790Abstract: When a current which is conducted from a direct current power supply 8 to a choke coil L1 after a switching transistor 7 is turned on has a predetermined value, an LED lighting device. lights up an LED series circuit by conducting a pulse-shaped current which occurs by turning off the switching transistor 7 to the LED series circuit. A cycle period at which the pulse-shaped current is generated is determined according to the average value of the current flowing through the LED series circuit by using an oscillator (VCO) 4. The LED lighting device controls each of the pulse-shaped current value and the average current value arbitrarily.Type: GrantFiled: September 18, 2009Date of Patent: September 17, 2013Assignee: Mitsubishi Electric CorporationInventors: Yu Inoue, Takashi Ohsawa

Patent number: 8536794Abstract: A system and method map dimming levels of a lighting dimmer to light source control signals using a predetermined lighting output function. The dimmer generates a dimmer output signal value. At any particular period of time, the dimmer output signal value represents one of multiple dimming levels. In at least one embodiment, the lighting output function maps the dimmer output signal value to a dimming value different than the dimming level represented by the dimmer output signal value. The lighting output function converts a dimmer output signal values corresponding to measured light levels to perception based light levels. A light source driver operates a light source in accordance with the predetermined lighting output function. The system and method can include a filter to modify at least a set of the dimmer output signal values prior to mapping the dimmer output signal values to a new dimming level.Type: GrantFiled: May 29, 2009Date of Patent: September 17, 2013Assignee: Cirrus Logic, Inc.Inventors: John L. Melanson, John J. Paulos
