In another aspect, the secondary optical facility does not directly exert pressure onto any primary optical element, thereby reducing optical misalignment.Type: GrantFiled: December 22, 2010Date of Patent: April 2, 2013Assignee: Koninklijke Philips Electronics N.V.Inventors: Derek Logan, Colin Piepgras

Patent number: 8408735Abstract: An actuating device for operating lamps (1) includes an actuator provided for actuating a number of first light-emitting diodes (6) for generating white light, on the one hand, and a number of second light-emitting diodes (7) for generating single-color light, on the other hand. A control is provided such that only the first light-emitting diodes (6) are switched on in a first operating state of the operating lamp (1) and such that the first light-emitting diodes (6) and the second light-emitting diodes (7) are switched on in a second operating state. The second light-emitting diodes (7) are designed such that a preset color rendering index is greater in the second operating state than in the first operating state of the operating lamp (1).Type: GrantFiled: November 16, 2010Date of Patent: April 2, 2013Assignee: Dräger Medical GmbHInventor: Hanno Kretschmann

Patent number: 8410708Abstract: A dual colored LED decoration lamp which includes a lamp string combined of multiple dual colored LED lights and a controller connected between the power supply and the lamp string. The lamp string includes lamp groups combined of multiple LED lights with two different colors and with their anodes and cathodes cross-linked. The multiple lamp groups are then connected in series, and each LED light in every lamp group is connected in same direction with the same colored LED light in the next lamp group. The controller controls the variation of the direction of current in aforementioned lamp strings. Thus, the lamp string is able to emit light with different colors by varying the current direction in the same lamp string through the usage of controller, and there is no need to set with multiple lamp strings.Type: GrantFiled: December 2, 2010Date of Patent: April 2, 2013Inventor: Fu-Hsien Hsu

Patent number: 8393779Abstract: Generally, existing LED lamps often use robust metallic cases since each of the cases functions as a heat sink. Various shapes for increasing the heat dissipation properties of the case have been employed; there is no unified shape. Existing LED lamps therefore have a problem that they cannot be easily disassembled at the time of recycling. Thus, an object is to provide a lamp which can be easily disassembled at the time of recycling. A lamp includes: a case having a certain shape; an LED module including a semiconductor light-emitting device; and a power supply circuit provided inside the case, for driving the semiconductor light-emitting device to emit light, wherein on an outer side of the case, a step for splitting the case is formed.Type: GrantFiled: January 7, 2011Date of Patent: March 12, 2013Assignee: Panasonic CorporationInventor: Minoru Myojo
