  • Patent number: 11441747
    Abstract: The present invention relates to different embodiments of lighting fixtures, such as high bay lighting fixtures, comprising one or more improved features. Some of these features include the direct mounting of emitters on a heat sink and/or the use of a template-like board for providing an electrical connection between emitters. These features can improve heat dissipation from the emitters and simplify fabrication. In other embodiments, expensive lens optics of prior art SSL fixtures can be replaced with a flat lens and reflector in order to produce a fixture having a satisfactory spacing criterion.

  • Patent number: 10527273
    Abstract: The present invention relates to different embodiments of lighting fixtures, such as high bay lighting fixtures, comprising improved features. One of these features can be a driver box placement that is displaced from the center of the fixture. In one such embodiment, the driver box can be mounted such that no portion is over the emitters. Another improved features is a heat sink with branching spokes. As they move away from the center of the heat sink, each of the spokes can branch into multiple spokes, which can improve conductive thermal dissipation. Empty spaces can be left between the spokes to improve convective thermal dissipation.

  • Patent number: 7211758
    Abstract: An apparatus and method to minimize teasing and contact welding at contact points includes a switch having a first contact movable toward a second contact from a switch-deactuated position to a switch-actuated position and movable away from the second contact from the switch-actuated position back to the switch-deactuated position. A transfer carriage is operatively engaged with the first contact and includes a flip-flop mechanism for bringing the first contact into contact with the second contact and releasing the first contact from the second contact. The flip-flop mechanism utilizes a transfer barrier to switch between the switch-actuated and switch-deactuated positions. An actuator imparts movement on the transfer carriage to overcome the transfer barrier when moving between the switch-deactuated and switch-actuated positions.

  • Patent number: 6958455
    Abstract: A trigger mechanism for a power tool includes a chassis; a trigger mounted to the chassis for movement between ON and OFF positions; an electrical switch mounted to the chassis for activation by movement of the trigger between the ON and OFF positions to close and open an electrical circuit; and a locking mechanism comprising a lock button and a latch, user-depression of the lock button causing deflection of the latch to enable depression of the trigger in the OFF position, the pushbutton retaining the latch deflected in the OFF position of the trigger until further depression of the trigger beyond the ON position releases the pushbutton from the latch to enable release of the trigger for return to the OFF position.
