Abstract
The invention discloses an improved device of an emergency escape indicator light, belonging to the technical field of electronics. The improved device comprises an AC (Alternating Current) power supply, a rectifier circuit, a storage battery, a capacitance detection unit, a light-emitting device and a power supply judgment unit and further comprises a power supply control unit; the improved device of the emergency escape indicator light has the beneficial effects that: when the power supply control unit receives a low-power signal, the power supply control unit is connected with the circuit to continuously charge the storage battery; when an electricity quantity detection unit detects that the storage battery is charged completely, a detection signal is transmitted to the power supply control unit; after receiving the signal, the power supply control unit disconnects the circuit so as to stop charging; and thereby, the purpose of saving energy source is achieved and the service life of the storage battery is prolonged.
Description
Technical field
The present invention relates to a kind of device of emergency escape indicator light, specifically is a kind of improved device of emergency escape indicator light, belongs to electronic technology field.
Background technology
The storage battery of present emergency escape indicator light on the market is in a kind of state of charging all the time, even electric weight has been expired; Also, damage storage battery easily, reduce the life-span of storage battery continuing charging; For fear of the generation of this situation, some insider works out a kind of emergency escape indicator light without storage battery, but uses dry cell instead; But dry cell stores electric weight very little, also need check frequently, places dead battery; Emergency lamp loses inefficacy, wastes time and energy, and does not meet economic benefit.
Summary of the invention
To the problem that above-mentioned prior art exists, the present invention provides a kind of improved device of emergency escape indicator light, can reach the effect of power saving effectively, reduces cost.
To achieve these goals, the technical scheme of the present invention's employing is: a kind of improved device of emergency escape indicator light comprises AC power; Rectification circuit, storage battery, capacitance detecting unit; Light-emitting device, the power supply judging unit also comprises power control unit; The output of AC power is electrically connected with the input of power control unit and power supply judging unit respectively; The output of power supply judging unit inserts light-emitting device, and the output of rectifier power source unit is received storage battery, and storage battery is electrically connected with the electric weight detecting unit; The output of power supply detecting unit is electrically connected with the input of light-emitting device and power control unit respectively, and the output of power control unit is connected to the rectifier power source unit.
The invention has the beneficial effects as follows: when power control unit was received the discontented signal of electric weight, power control unit can be connected circuit, continues charging; When the electric weight detection has expired to the electric weight of storage battery, can the signal that detect be sent to power control unit, after power control unit is received signal; The meeting open circuit; Thereby stop charging, reach the purpose of energy savings, prolong the useful life of storage battery.

Embodiment
To combine accompanying drawing that the present invention is described further below.
As shown in Figure 1, a kind of improved device of emergency escape indicator light comprises AC power; Rectification circuit, storage battery, capacitance detecting unit; Light-emitting device, the power supply judging unit also comprises power control unit; The output of AC power is electrically connected with the input of power control unit and power supply judging unit respectively, and the output of power supply judging unit inserts light-emitting device, and the output of rectifier power source unit is received storage battery; Storage battery is electrically connected with the electric weight detecting unit, and the output of power supply detecting unit is electrically connected with the input of light-emitting device and power control unit respectively, and the output of power control unit is connected to the rectifier power source unit.
Full when the electric weight detection to the capacitance of storage battery, will send to power control unit and expire signal, after power control unit is received signal; Auto power off stops charging, when the power supply detection arrives the capacitance deficiency of storage battery; Send signal to power control unit, after power control unit is received signal, connect circuit; Continue charging, thereby reach purpose of power saving, prolong the useful life of storage battery.
