Emergency lighting device based on small electric signals in detection circuit

Abstract

The invention relates to an emergency lighting device based on small electric signals in a detection circuit, which is characterized by comprising a small signal detection module (C1-1), an AC-DC conversion module (C1-2), a switch switching circuit (C1-4), a battery (E) and a luminescence lighting device (L1). The whole system does not need to change any line layout of a traditional emergency lighting device, and can realize an integrated function of emergency lighting and general lighting by only changing a traditional light source or a lamp and a circuit breaker or a switch directly, thereby saving tedious process and high cost in independent wiring of a traditional emergency lighting line, improving the utilization rate of lighting device itself, bringing convenience to construction, saving resources for production and life, and saving the cost.

Description

Technical field [0001] The patent of the present invention relates to a technical field in which an emergency lighting device can automatically light up when the power grid is cut off, and specifically relates to an emergency lighting device based on detecting tiny electrical signals in a circuit, and furthermore, it is a device that can detect whether the circuit is There is a small electrical signal to judge whether the emergency lighting function should be activated. Background technique [0002] Traditional emergency lighting devices are usually divided into two categories, one is that it can only play a lighting function during a power outage emergency, and the lighting device in the emergency lighting device cannot be used as a general lighting when there is mains power. This emergency lighting device usually has great limitations: firstly, this system can only be turned on when the power is out of emergency, and the lighting device cannot be used as general lighting w...

[0002] Traditional emergency lighting devices are usually divided into two categories, one is that it can only play a lighting function during a power outage emergency, and in the case of mains power, the lighting device in the emergency lighting device cannot be used as a general lighting

This kind of emergency lighting device usually has great limitations: first, this kind of system can only be turned on when the power is out of emergency, and the lighting device cannot be used as general lighting when there is electricity, which is a great waste of resources

However, this kind of inductive emergency lighting device also has certain limitations. It can only be used in residential areas and families. For some environments with chaotic wiring and complicated electrical signals, it will often fail due to mutual interference of signals or instability of signals. Cause system misjudgment or control failure
