Abstract

The invention discloses an emergency LED lamp. The emergency LED lamp comprises a LED module for emitting light when being connected with a power supply, an external control switch used for controlling on-off of a voltage transforming circuit, the voltage transforming circuit and a control unit circuit. The voltage transforming circuit is used for transforming the voltage when the external control switch is conducted and providing a power supply for the LED module. The control unit circuit is used for automatically switching the power supply and controlling the LED module to emit the light. The control unit circuit comprises a main control circuit and a rechargeable battery. When the municipal grid provides electricity and the control switch is conducted, the LED module emits light and the rechargeable battery is charged. When the municipal grid does not provide electricity and the control switch is conducted, a control circuit controls the rechargeable battery to provide power for the LED module and turning on the LED module. Thus, no matte whether the external power supply is on or off, the same control switch can be used for turning on or turning off the LED module.

Description

technical field

[0001] The invention relates to the technical field of LED lighting, in particular to an emergency LED lamp with convenient installation, simple operation and energy saving. Background technique

[0002] Due to the advantages of energy saving, environmental protection, high luminous efficiency, and long life, LED lights have been rapidly applied to various fields. Based on the AC / DC dual-purpose lamps currently on the market, it is necessary to set an AC / DC conversion switch and a switch to control the light on and off on the lamp, which is convenient to use, especially when the lamp is installed at a high place. Inconvenient; and the existing LED lighting lamp has a single function and cannot realize the multi-purpose function of one lamp. In the prior art, when many fire emergency lights are powered off during the day, the emergency lights will automatically turn on. If the power fails for a few hours, the battery power in the lights will be exhausted. Th...
