  • Publication number: 20250093000
    Abstract: A portable illumination apparatus such as, for example, a task light, that is lightweight and compact to provide enhanced illumination in an ambient environment when placed in one of a plurality of operating modes. The portable illumination apparatus includes a support base and a light module that includes one or more light sources and a rechargeable power source. The light module may be manually manipulated for movement between a collapsed, stowed position and a deployed position by rotation of about a first rotational axis. In the deployed position, the light module is rotatable about the second rotational axis that is perpendicular to the first rotational axis. The support base incorporates a carabiner clip member that facilitates secure attachment of the portable illumination apparatus to an object or surface in a manner that facilitates hands-free use of the portable illumination apparatus.

  • Publication number: 20230383932
    Abstract: A portable flashlight apparatus is provided that is lightweight and compact to provide enhanced illumination in an ambient environment when placed in one of a plurality of operating modes. The portable flashlight apparatus includes a base housing defining an interior space and which includes structurally defined regions that include a front housing region, a rear housing region, an intermediate housing region extending between the front housing region and the rear housing region and an end cap that closes the interior space at the rear housing region. A light module includes a first light source operable to emit illuminating light, a second light source operable to emit laser light, and a third light source operable to emit illuminating light. A magnet are arranged at the rear face of the end cap, and is operable to magnetically bias the base housing on a working surface or support surface having magnetic properties.

  • Patent number: 8336641
    Abstract: The present invention relates to a power tool comprises an adjusting mechanism, the adjusting mechanism comprising a station element defining at least a first engaged member, and an adjusting member rotated about a axis and driving the first engaged member to move elastically along the axis, wherein a frequency increase mechanism is disposed between the adjusting member and the station element, the frequency increase mechanism coupled to the first engage member, the frequency of the elastic moving of the first engage member increases when the adjusting member rotates about the axis. Because the adjusting mechanism can increase the sound frequency, so it can make precision and dense sound and remind of the operator when the adjusting member rotated.
