  • Patent number: 12089351
    Abstract: A power supply apparatus is provided including a housing, at least one battery receptacle for receiving at least one removable battery pack, an inverter that converts a direct-current (DC) signal from the at least one battery pack to an alternating-current (AC) signal, and a controller that applies a pulse-width modulation (PWM) signal to the inverter to shape the AC signal with a lower harmonic distortion relative to a square wave. For each full cycle of the AC signal, the controller sets the duty cycle to approximately 100% within a first period corresponding to a peak area of the AC signal, to less than approximately 100% but greater than approximately 0% within a second period in which the AC signal transitions from the peak to a zero-cross following the first period, and to 0% within a third period corresponding to the zero-cross of the AC signal following the second period.

  • Patent number: 11543093
    Abstract: A lighting apparatus is provided with a housing forming a battery housing and a light housing separated via a partitioning wall. A light module is supported by the light housing and includes a heat sink located at least partially within the light housing and at least one LED supported by the heat sink. A battery receptacle formed within the battery housing to slidingly receive a battery pack at least partially into the battery housing. An intake opening is formed within the partitioning wall and an air vent is formed in fluid communication with the light housing. In operation, an airflow passes in thermal contact with the battery pack from the battery housing into the light housing through the intake opening, and from the light housing in thermal contact with the heat sink out of the air vent.
