Abstract
The utility model discloses an emergency lighting device includes at least: the lamp comprises a switch, a standby power supply module and a lamp, wherein the switch is coupled with a mains supply, when the mains supply is powered off, the lamp can be switched to a standby power supply mode when the switch is in an open state, the standby power supply module provides the standby power supply, so that the lamp continuously emits light within a certain time length, and the lamp is extinguished when the standby power supply is used.
Description
Technical field
The utility model is about a kind of emergency lighting device, refers to especially a kind ofly can when power-off, still can have the emergency lighting device of illuminating effect.
Background technology
Light-emitting diode (Light Emitting Diode, LED) possesses and has that volume is little, power saving and the feature such as durable, and because light-emitting diode processing procedure and output promote, cost is reduced day by day.Therefore, light-emitting diode becomes a new generation's light source with strongest influence power gradually, and it is widely used in various terminal equipments and lighting field.
In general, in the Driving technique of light-emitting diode, when supply voltage starts to provide, drive unit can convert supply voltage to driving voltage, to drive light-emitting diode to produce light source.When stopping providing supply voltage, drive unit can not provide driving voltage, and light-emitting diode extinguishes immediately.Yet, stopping providing supply voltage and the light source of light-emitting diode is extinguished immediately, user cannot do some simple things (such as taking key etc.) after light source extinguishes again, and reduces the convenience using.Also or, because of natural disaster or man-made disaster, cause the situation of power-off, allow in the rather dark or not enough occasion of dull thread and be plunged in darkness once again, and the people who is in this environment also feels uneasy because of precipitate dark surrounds, even jeopardize the safe facts.
In view of this, U.S. Patent number proposes a kind of illuminating lamp (Lighting Lamp) for No. US7688008, it can be after stop supplies supply voltage, by driving timing device (Timer) and pulse-width modulation (Pulse Width Modulation, PWM) signal generator drives light-emitting diode conducting luminous, with extinguishing of the light source of delayed luminescence diode.Yet aforementioned patent is used timer and pulse width modulation signal generator, may increase complexity and the use cost of circuit design, so the drive circuit that extinguishes of the light source of delayed luminescence diode, the space being still improved.
Utility model content
The technical problem that the utility model solves still can have the emergency lighting device of illuminating effect can be in power-off time providing a kind of.
The technological means that the utility model adopts is as described below.
For on reaching, take off object, emergency lighting device of the present utility model at least includes: the switch, stand-by power supply module and the light fixture that are coupled to civil power, this stand-by power supply module is coupled to this switch, it is provided with charging control unit and the electricity accumulating unit mutually coupling, and this light fixture is provided with control unit, driver element and light emitting source, this driver element couples mutually with this control unit and light emitting source respectively, by this control unit, coupled mutually with this switch and stand-by power supply module respectively, can control by this civil power or by this stand-by power supply module whether supply electric power.
Wherein, civil power is during power-off, in switch for the state of opening under, light fixture is changeable luminous for using utility mode ，You city electric drive light fixture to continue, and civil power charges to this stand-by power supply module simultaneously; When civil power power-off, under the state in switch for unlatching, light fixture is changeable provides stand-by power supply for using standby power mode by stand-by power supply module, light fixture is continued in a time span luminous, treats that exhausted this light fixture of stand-by power supply extinguishes.
According to above-mentioned technical characteristics, described light emitting source is light-emitting diode.
According to above-mentioned technical characteristics, described electricity accumulating unit can be storage battery or capacitor.
According to above-mentioned technical characteristics, the alternating current that described charging control unit can provide civil power is converted to direct current.
According to above-mentioned technical characteristics, the alternating current that described driver element can provide civil power is converted to direct current.
According to above-mentioned technical characteristics, described charging control unit can be charged when saturated in this electricity accumulating unit, controls civil power and stops this electricity accumulating unit charging.
The beneficial effect that the utility model produces: still can there is illuminating effect during power-off.

Embodiment
As shown in Fig. 1 the utility model one preferred embodiment emergency lighting device structural representation, this emergency lighting device at least includes: the switch 2, stand-by power supply module 3 and the light fixture 4 that are coupled to civil power 1, wherein: stand-by power supply module 3 is coupled to switch 2, stand-by power supply module 3 is provided with charging control unit 31 and the electricity accumulating unit 32 mutually coupling; The alternating current that charging control unit 31 can provide civil power 1 is converted to direct current, and 32 of the electricity accumulating units direct current by reception is stored, and charging control unit 31 can when saturated, controlled civil power and stop this electricity accumulating unit charging in electricity accumulating unit 32 chargings; Electricity accumulating unit 32 can be storage battery or capacitor.
During use, as shown in Figures 2 and 3, control unit 41 continues detecting civil power 1 power supply situation, when civil power 1 is not de-energized, under state in switch 2 for unlatching, control unit 41 can switch to light fixture 4 civil power 1 pattern of using, and drive light emitting source 43 stabilized illuminations, and civil power 1 charges simultaneously to see through driver element 42 through 31 pairs of electricity accumulating units 32 of charging control unit.
When civil power 1 is de-energized, as shown in Figures 3 and 4, under state in switch 2 for unlatching, control unit 41 can switch to use standby power mode by light fixture 4, by stand-by power supply module 3, provide stand-by power supply, via electricity accumulating unit 32, see through driver element 42 and drive light emitting source 43 stabilized illuminations, light fixture 4 is continued in a time span luminous, treat that 4 of the exhausted light fixtures of stand-by power supply extinguish.
It is worth mentioning that, stand-by power supply module of the present utility model and this light fixture, for independently individual, can be installed individually and keep in repair, and light fixture is when power-off, its state for complete bright when extinguishing complete dark state, to reach the lighting hours that extends lighting device, and can maintain certain illuminating effect.
