Description

Technical Field

[0001] This utility model relates to a lamp. Background Technology

[0002] Current LED lights are generally powered by mains electricity, so they cannot be used when the mains power is cut off. However, with the increasing demand for LED lights, there is a need for them to still be usable after the mains power is cut off.

[0003] To address the aforementioned technical problems, patent application number 202411348548.5 discloses an LED lighting fixture, comprising a light source, a driving module for driving the light source, and a power supply module for supplying power to the driving module. The power supply module is electrically connected to the driving module. The driving module has a first plug-in terminal electrically connected to the light source. The LED lighting fixture also includes a connector and an emergency module. The connector has a second plug-in terminal, and the emergency module has a third plug-in terminal. The connector and the emergency module can be selectively operated, thus enabling the LED lighting fixture to have two operating states: In the first operating state, the second plug-in terminal of the connector engages with the first plug-in terminal of the driving module, allowing the driving module to conduct electricity with the light source; in the second operating state, the third plug-in terminal of the emergency module engages with the first plug-in terminal of the driving module, allowing the emergency module to conduct electricity with the light source, thereby driving the light source to operate through the emergency module. This design not only requires replacing connectors and emergency modules for different occasions, making disassembly and assembly cumbersome, but also easily damages the LED chips because the power module connects to the light source through the driver module and emergency module. In addition, it increases the number of quick-connect wires, greatly shortening the lifespan of the lamp. Utility Model Content
