Systems, apparatus, and methods for managing power in a hybrid battery cartridge. The hybrid battery cartridge may output single-use battery power, rechargeable battery power, or both. Thus, a single battery cartridge may store multiple types of batteries and allow the batteries to be used separately or concurrently. In one example usage, the battery cartridge may be inserted into other devices to provide power. Additionally, the intelligent hybrid battery cartridge may be used as a stand-alone charger to charge other devices. The intelligent hybrid battery cartridge is designed to allow for retrofitting into existing single-use battery powered devices such as flashlights and lanterns to make them hybrid power enabled. The hybrid battery cartridge may select a power source based the type of load and/or on a reserve power threshold.

The present disclosure provides a power supply device and a high-power illumination system. The power supply device includes: a housing, where the housing includes a first bottom plate having a first surface on which a first heat sink is provided and a second surface on which a thermal conductive potting layer is provided; and a printed circuit board, where the printed circuit board is located in the housing, the printed circuit board includes a circuit board body and multiple electronic components arranged on the circuit board body, at least part of the multiple electronic components is arranged facing the second surface of the first bottom plate, and the electronic component of the at least part of the multiple electronic components is partially immersed in the thermal conductive potting layer to conduct heat dissipated by the electronic component to the first heat sink for natural heat dissipation of the electronic component.

A security light having optional connection to multiple power supplies. The lighting controller can sense the appropriate connected supply and automatically connect to three different power supplies which include house voltage connection through a typical junction box, a remote solar charging station, and on-board batteries that can be used as a third backup power supply. Additional implementations include power outage detection and backup illumination along with low voltage power supply from a mounting structure.

An annular LED grow light is disclosed, which comprises a radiator, a light source board, and a power supply box. The light source board is composed of a PCB light board and a plurality of LED lamp beads, wherein the LED lamp beads are arranged on the PCB light board in an annular array about a center. The beneficial effects of the present disclosure are: the photosynthetic photon flux density (PPFD) is distributed more evenly after the LED lamp beads are arranged in an annular array about the center, thus the effective irradiated area is larger, and the cost has been saved.

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.

A circuit board configuration adapted to carry electronic components of a power supply module is provided. The circuit board configuration comprises: a first circuit board, having a first plane configured to dispose and connect a part of the electronic components; and a second circuit board, electrically connected to the first circuit board and having a second plane configured to dispose and connect another part of the electronic components, wherein at least one of the first and the second circuit boards is disposed, perpendicular to an axial direction of the lamp tube, in an interior space formed by the lamp tube and at least one of the two end caps, so that the a direction normal to the first and the second planes is substantially parallel to the axial direction of the lamp tube.

The present disclosure is directed to wallpacks containing at least one light source, such as a light-emitting diode (LED). The wallpack light fixtures disclosed herein generally contain a housing, at least one light source, a power supply, and a plurality of heat sink fins.

A hand-held spotlight, having: a housing provided with an accommodating cavity; a power supply box detachably disposed in the accommodating cavity; a switch base connected to the housing and provided with a first clamping block; and a cover body hinged with the housing, wherein the cover body is capable of covering an opening of the accommodating cavity to confine the power supply box within the accommodating cavity, and the cover body is provided with a second clamping block, which is clamped with the first clamping block when the cover body covers the opening of the accommodating cavity, thereby restricting the flipping of the cover body.

A self-balancing floating battery case, comprising an upper casing and a lower casing, wherein the upper casing and the lower casing are connected by threads, a height of the upper casing is bigger than a height of the upper casing. A light opening is provided at an intermediate portion of the upper casing away from a center of the upper casing, a box surrounding the light opening is provided on an inner wall of the upper casing, the box is divided to be a PCB cavity and a battery cavity, a main body of the light opening deviates towards the PCB cavity and a main body of the battery cavity deviate towards the center of the upper casing. In the present invention, existing structures are modified, the battery case has a higher waterline, entrance of water can be prevented; and eccentricity of the center of gravity is corrected by weight.

A tool lamp with a mobile power source, having a handle, a movable lamp base, and a mobile power box, wherein the handle is provided with a power chamber and a sliding slot, the power chamber has a strip-shaped opening, and a lock piece and a bottom hole are disposed in the power chamber; the movable lamp base is detachably connected to the handle; and the mobile power box is inserted into the power chamber via the strip-shaped opening, a push member is disposed in the mobile power box, is located in the bottom hole and is able to push the mobile power box out of the power chamber, and a groove portion is formed in a side wall of the mobile power box.
