Publication number: 20120136493Abstract: A heat sink for a handheld device is formed as a one piece chassis for supporting heat-producing circuits inside the device while having heat radiating surfaces outside the device. In another embodiment a battery pack control circuit under microprocessor control allows battery packs having different battery chemistries and characteristics to be interchanged in the same device without switches or adapters. Control of operating modes of the device despite changes in the battery pack including battery chemistry, state of charge, available voltage, or desired operating mode are automatic. The microprocessor measures the battery pack characteristics, using look up tables in a suitable program to adjust the circuit operating modes.

Patent number: 7841735Abstract: A battery operated fluorescent lamp is disclosed, which is operable from the battery while the battery is being recharged, comprising a tubular housing configured as a handle grip at one end and a cylindrical lens portion at the other end. The tubular housing lockably connects to a battery pack. The cylindrical 3030 lens portion encloses a miniature fluorescent bulb. The electrical circuitry, enclosed within the handle grip and alternately operable from either 120 VAC or 12 VDC, includes a converter circuit, a battery charging circuit, and a fluorescent lamp ballast circuit. The battery pack is electrically coupled to simultaneously receive charging current from an output of the charging circuit and to deliver DC supply voltage to the fluorescent lamp ballast circuit without the occurrence of a net discharge of the battery pack.Type: GrantFiled: August 28, 2008Date of Patent: November 30, 2010Assignee: Bayco Products, Ltd.Inventors: James Newton, Bijan Bayat

Patent number: 7745957Abstract: A single combination task lamp and flashlight instrument, providing separate flood and spot light beams, independently controlled in a three-state sequence by simple push button switches. The two kinds of light beams are produced by separate arrays of compact light emitting devices. both arrays are driven by a single, rechargeable battery powered electrical circuit that provides separate, regulated constant currents to the respective arrays of LEDs. The optics and electronics are constructed in a single, ruggedized, compact module. The module is enclosed within an elongated handle that positions the center of mass for optimum balance of the instrument and the control switches for convenient operation according to the sense of touch.Type: GrantFiled: December 15, 2006Date of Patent: June 29, 2010Assignee: Bayco Products, Ltd.Inventors: Bijan Bayat, James Newton, Robert Lee Ellis, Gordon L.

Patent number: 7625099Abstract: An LED lighting array is disclosed wherein a plurality of light emitting devices disposed in at least first and second columns are mounted on a planar mounting surface to form an emission plane. The emission axes of all the LEDs in a first column are parallel with each other and lie in a first plane. The emission axes of the LEDs in an adjacent, second column are also parallel, but a second plane containing the emission axes of the second column is disposed at a predetermined, non-zero angle with respect to the first plane. The non-zero angle is a function of the LED beam width and the distance to a lighting target. This configuration of the LEDs provides an optimum balance at a predetermined target distance between the size of the area illuminated and the brightness of the illumination of the target. In one aspect of the invention the LED lighting array includes at least first, second and third columns of LEDs.Type: GrantFiled: December 31, 2007Date of Patent: December 1, 2009Assignee: Bayco Products, Ltd.Inventors: James Newton, Bijan Bayat
