It should be noted that stand-by power supply 3b is preferably that not connect power-off source (be called for short UPS) longer than the time that general power supply is powered, and reaches about 40 minutes, be suitable for and be arranged on large-scale occasion or the more occasion of people.
In an embodiment, shown in Fig. 3, the space shared in the lamp vessel 1 for reducing each parts. So by fairing 42, conventional power supply 3a, and automatic power-supply switch 41 is integrated on one block of control circuit plate 4, and control circuit plate 4 is positioned at fluorescent tube 1 one end, and stand-by power supply 3b amount of storage requires relatively low, and volume can be relatively larger accordingly, so stand-by power supply 3b being arranged on the lower section of whole lamp bar 23. Referring to Fig. 4, charging device 43 is arranged on another control circuit plate 4 simultaneously, and is positioned at the other end of fluorescent tube 1, so can be effectively reduced the floor space in fluorescent tube 1, be possible not only to reduce the usable floor area of fluorescent tube 1, it is possible to improve illumination brightness. Certainly in other embodiments, can by conventional power supply 3a and stand-by power supply 3b, and fairing 42, charging device 43 and automatic power-supply switch 41 are fully integrated on one block of control circuit plate 4, and control circuit plate 4 is positioned at fluorescent tube 1, it is also possible to the above-mentioned control circuit plate 4 being arranged on two ends is combined into one.
During actual installation, after installing control circuit plate 4, control circuit plate 4 is being connected with binding post 24, finally lamp holder 11 is being connected with fluorescent tube 1. Certainly in other embodiments, control circuit plate 4 also can be directly mounted in fluorescent tube 1, simplifies installation procedure.
In an embodiment, shown in Fig. 7, wherein, LED emergency light can use under different conditions, and the automatic power-supply switch 41 that stand-by power supply 3b and conventional power supply 3a is all connected with plays vital effect, realize under conventional illumination condition and switching between LED lamp source 2 and different electrical power 3 under emergency lighting state, powered for LED lamp source 2 by different power supplys 3.
In an embodiment, preferably can improve the scope of application of LED emergency light, simplify procedures, it is possible to be arranged to control in the microwave remote sensor of whole circuit, infrared inductor or acoustic control induction apparatus further on control circuit plate 4 one or more. Conveniently in emergency circumstances enable LED emergency light, it is to avoid do not enable the unnecessary injury that LED emergency lighting etc. causes in time.
Referring again to Fig. 6,7, present invention also offers the using method of a kind of LED emergency light, concrete including is that concrete using method includes to the use of LED emergency light in above-described embodiment:
A), by lamp socket 5 mounted externally for fluorescent tube 1;
B), energising time, in external communication electricity input rectifying device 42;
C), fairing 42 convert external communication electricity to unidirectional current, the unidirectional current of conversion input respectively by binding post 24 and commonly uses in power supply 3a and stand-by power supply 3b;
D), switching circuit by automatic power-supply switch 41: under conventional illumination condition, stand-by power supply 3b and emergency light source 22 disconnect, conventional power supply 3a is connected with primary light source 21;
Under emergency lighting state, conventional power supply 3a disconnects with primary light source 21, and stand-by power supply 3b is connected with emergency light source 22.
Referring again to Fig. 6, wherein the fluorescent tube 1 of LED emergency light and common LED daylight lamp 6 can be that mixing is contained on a lamp socket 5, or by LED emergency light directly when common LED daylight lamp 6 with.
Time specifically used, it be connected with outside zero line N and live wire L by fairing 42, the voltage of 220V is converted to the voltage of 12V, in the conventional power supply 3a of one part of current input, and in the electric current of another part input stand-by power supply 3b, in order to store.
Such as LED emergency light is being worked as common LED daylight lamp 6 used time, the automatic power-supply switch 41 that can utilize setting realizes, the concrete relay in automatic power-supply switch 41, during utilization, conventional power supply 3a is connected on the normally opened contact (being called for short NO) of relay, stand-by power supply 3b is connected on relay normally-closed contact (being called for short NC), and when after the coil electricity of relay, normally-closed contact NC disconnects, normally opened contact NO closes normal illumination after LED lamp source 2 is energized, when coil losing electricity after conventional power supply 3a power-off, normally opened contact NO disconnects, normally-closed contact NC Guan Bi starts stand-by power supply 3b and is connected with LED lamp source 2, start emergency lighting, for further distinguishing state, LED lamp source 2 is made up of primary light source 21 and emergency light source 22, different by the brightness in two kinds of lamp sources and/or color, play the effect of warning. it is concrete it should be noted that when being only used as LED daylight lamp 6 and using, the light source colour that LED lamp source 2 sends is white, and the light source colour that LED lamp source 2 sends under emergency conditions is blue. concrete warning color can adopt different colors according to practical situation.
It should be noted that, mainly through microwave sensor, infrared inductor or acoustic control induction apparatus or either directly through the sensing of automatic power-supply switch 41 self, when finding just also can to automatically switch to stand-by power supply 3b when conventional power supply 3a no current flows into, concrete control mode repeats no more.
It should be noted that, above-described embodiment all can independent assortment as required. The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, under the premise without departing from the principles of the invention; can also making some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention.
