The LEDs (preferably two per segment) are mounted upon a thermally efficient printed circuit board such as a flex-on aluminum board.Type: GrantFiled: April 5, 2005Date of Patent: October 2, 2007Assignee: Osram Sylvania, Inc.Inventors: Charles M. Coushaine, Michael Tucker, Thomas Tessnow

Patent number: 7264384Abstract: An integrated marine vessel hardtop and navigation lighting system, for use on boats having a hardtop or platform which covers the helm, bridge, cockpit or similar areas. The system includes a hardtop having recessed voids which receive specially designed starboard, port and stern integral lighting assemblies and LED matrix array modules. The lights provide improved chromaticity and luminosity in desired angular fields of light, and further having arcuate surfaces which complement port and starboard lenses having mating surfaces. The lighting system is secured and self contained and coterminous with the hardtop. The hardtop and lighting modules constitute a generally unitary and stealth assembly, the light fixtures being integrated within said hardtop means in an unobtrusive manner without protuberances.Type: GrantFiled: February 16, 2005Date of Patent: September 4, 2007Assignee: Pipewelders, Inc.Inventors: Peter Derek Ryan, Edward Ray Hughes, Javier Alejandro Carbi Haubold

Patent number: 7261447Abstract: An emergency vehicle light bar is provided with a flexible support that can be curved to match the curvature of the top edge of a vehicle window when installing the light bar on the vehicle, giving the light bar a low profile relative to the vehicle and giving the vehicle a stealth or “unmarked” appearance.Type: GrantFiled: July 21, 2003Date of Patent: August 28, 2007Assignee: PowerArc, Inc.Inventors: W. Kenneth Menke, W. Kenneth Menke, III

Patent number: 7258466Abstract: A lighting unit for a vehicle includes a light emitting diode unit, a plate-shaped radiating board having an upper surface to which the light emitting diode unit is directly fixed, and a feeding connector connected electrically to the light emitting diode unit at the end of the radiating board and having an input portion for a power to be supplied to the light emitting diode unit below the radiating board. The feeding connector is provided on the end of the radiating board and there may further be provided a wiring extended from the light emitting diode unit toward the end of the radiating board over the upper surface of the radiating board and connected to the feeding connector at the end.Type: GrantFiled: January 24, 2005Date of Patent: August 21, 2007Assignee: Koito Manufacturing Co., Ltd.Inventors: Shigeyuki Watanabe, Hironori Tsukamoto

Patent number: 7244053Abstract: A signaling system for mounting to an exterior surface of an emergency vehicle is provided. The signaling system includes a light bar and a pair of mounting feet. The light bar can include a plurality of signaling devices supported on and distributed along a base member and enclosed by a cover. The light bar can be secured to the mounting feet via a plurality of fasteners. The mounting feet can be connected to the emergency vehicle via roof straps. Each mounting foot can include a base, which can have a support portion, a contoured portion, and a pair of compartments; a pair of seals associated with each compartment; a pair of covers, which can be translucent, removably mounted to the base to enclose the compartments; and a roof strap secured to the base. Each compartment can house a signaling device, such as a lamp assembly.Type: GrantFiled: March 25, 2004Date of Patent: July 17, 2007Assignee: Federal Signal CorporationInventors: Joseph F. Bader, Jan C. Mol, Sigmund S. Urbanski, Charles P. Meyer, Robert A. Czajkowski

Patent number: 7245228Abstract: A portable electronic apparatus has light sources that can be controlled to produce decorative or informational effects. Each light source is controlled by the combination of an enable signal from a 1-bit port of a controller and a PWM signal from a PWM signal from the controller. Each PWM signal is used to control a plurality of light sources in parallel whereas each 1-bit enabled signal controls, generally, only one. The light sources are preferably arranged to shine through soft structures on the apparatus.Type: GrantFiled: May 27, 2004Date of Patent: July 17, 2007Assignee: Nokia CorporationInventors: Thomas Fussinger, Victor Burger, Maik Kobald, Panu Johansson

Patent number: 7244057Abstract: Optical axes are simultaneously adjusted by tiltably mounting a plurality of lighting device units on a common unit support member. A rectilinear propagation blocking member of each lighting device unit is fixed with screw via the elastic bush to the unit support member, so that the optical axis can be adjusted. Due to the above structure, even when the accuracy of shapes of the rectilinear propagation blocking member and the unit support member are not sufficiently ensured and also even when the accuracy of the attaching work can not be sufficiently ensured, the optical axes of the lighting device units can be arranged in order by adjusting the optical axis of the rectilinear propagation blocking member.Type: GrantFiled: December 3, 2004Date of Patent: July 17, 2007Assignee: Koito Manufacturing Co., Ltd.Inventors: Shigeyuki Watanabe, Naoki Tatara, Kazuki Okui, Hirohiko Ohshio
