UTILITY LIGHT, COMBINATION OF BATTERY PACK AND UTILITY LIGHT, AND ELECTRIC TOOL

Provided are a tool lamp, a combination of a battery pack and a tool lamp, and a power tool. The tool lamp includes a lighting module, an adapter interface, a direct current interface, a two-way control module, and a one-way control module. The adapter interface is configured to be connected to a battery pack capable of being detachably connected to the tool lamp. The direct current interface is configured to be capable of being selectively connected to an external power consumption device or an external power supply device. The two-way control module is connected in series between the direct current interface and the adapter interface, where the two-way control module is configured to adjust electric power of the external power supply device according to a control signal of the direct current interface to form an electric power input adapted to the battery pack so that the external power supply device charges the battery pack; or the two-way control module is configured to match a discharge voltage of the battery pack with a power supply voltage required by the external power consumption device according to the control signal of the direct current interface so that the external power consumption device is powered. The one-way control module is connected in series between the direct current interface and the lighting module and connected in series between the adapter interface and the lighting module, where the one-way control module is configured to convert the electric power of the external power supply device or electric power of the battery pack into an electric power input adapted to the lighting module.
