Problems solved by technology

Yet this moment, the mains switch on the wall just can't control the opening and closing of electric light, and to turn off electric light, just must manually close the output switch of uninterruptible power supply, and this contradicts with people's daily life custom, brings people's life inconvenience
For another example, the common emergency lights hanging in the stairwell will automatically turn on when the mains power is interrupted, but they cannot be turned off when they do not need to be turned on.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to an uninterruptible power switch circuit and an LED lighting circuit using the same. Background technique [0002] Electricity is an essential material condition for industrial production and people's life in modern society. However, due to power supply shortage or line failure, the city power supply may be interrupted suddenly, which will have a greater impact on industrial production and people's life. In order to solve the problem of sudden interruption of power supply, the current common practice is to provide uninterruptible power supply. When the mains power supply is suddenly interrupted, the uninterruptible power supply can automatically start to supply power for electrical equipment, avoiding sudden voltage surges in machinery equipment or household appliances. change and damage. [0003] However, the power supply system of the uninterruptible power supply and th...
