  • Patent number: 8729851
    Abstract: A battery pack features a shock-absorbing and sealed construction and an electronic control module that provides automatic recovery circuitry in the event of a short circuit in the load whereby the power is terminated and then restarted at a lower level so that removal of the short circuit may be detected. Full power is restored to the load when the short circuit is removed. In addition, the electronic control module of the battery pack uses the battery pack load, such as a cap lamp, to provide an indication of a low battery charge level. The electronic control module also provides a soft-start feature where the power provided to the bulb is ramped up to avoid current in-rush to the bulb during startup.

  • Patent number: 8575893
    Abstract: A portable lighting device that is lightweight and features a space-efficient design includes a body containing a Lithium-ion (Li-ion) battery. The body includes a pair of pivot arms that are spaced from one another. A lamp assembly includes a lamp assembly housing containing a light source that is powered by the Li-ion battery. The lamp assembly housing is pivotally connected to each of the pair of pivot arms and positioned there between. A handle includes a gripping portion that is spaced from the body so that a gripping space is defined between the gripping portion of the handle and the body. A removable bumper pad is positioned on the bottom of the body. The portable lighting device features recesses on opposite sides that are engaged by corresponding tabs on a charging rack. This prevents non-compatible lighting devices from being positioned on the charging rack.
