Abstract
The invention provides an emergency lamp. The emergency lamp comprises a shell, wherein a basal plate is arranged in the shell, and is coated with fluorescent powder as an indication mark; and a light emitting diode chip is arranged between the basal plate and the fluorescent powder. When a power supply normally works, the emergency lamp is used as an illumination lamp; when the power supply is cut off, the fluorescent powder emits light to display as the indication mark, and the emergency lamp achieves an emergent indication effect. As the fluorescent powder emits light without needing an emergency lamp accumulator to supply power, the normal operation of an illumination system of the emergency lamp is not influenced by the failure of the power supply.

In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
The structural representation of Fig. 1 a kind of emergency light disclosed in the embodiment of the present invention;
The structural representation of Fig. 2 another kind of emergency light disclosed in the embodiment of the present invention;
The structural representation of Fig. 3 another kind of emergency light disclosed in the embodiment of the present invention;
The structural representation of Fig. 4 another kind of emergency light disclosed in the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
See Fig. 1, the embodiment of the invention discloses a kind of structural representation of emergency light, comprise: shell 11, substrate 12 is provided with in shell 11, substrate 12 is coated with into the fluorescent material 13 of Warning Mark, light emitting diode (Light-Emitting Diode is called for short LED) chip 14 is provided with between substrate 12 and fluorescent material 13.
So, when power supply normally works, emergency light uses as general lighting lamp, and when dump, fluorescent material 13 luminescence is also shown as Warning Mark, and now, emergency light plays the effect of emergent instruction.Because fluorescent material 13 luminescence is without the need to emergency light storage battery power supply, therefore, power cut-off can't affect the normal operation of emergency light illuminator.
Further, emergency light provided by the invention not only can be applied to both sides, passageway, can also be applied to ceiling top, for common emergency light, emergency light provided by the invention combines illumination and emergent two kinds of effects, thus can save the installation of Warning Mark, economize energy and cost.
Wherein, Warning Mark can be arrow, or is other marks that can point the direction, and the present invention does not limit at this.
It should be noted is that, light-emitting diode chip for backlight unit 14 is welded on the circuit board 15 be positioned on substrate 12.Wherein, circuit board 15 can be flexible PCB.
It will be understood by those skilled in the art that, fluorescent material 13 and a light-emitting diode chip for backlight unit 14 can be packaged into a lamp pearl 16, then multiple lamp pearl 16 being formed Warning Mark is fixed on substrate 12, specifically see Fig. 2, and the structural representation of another kind of emergency light disclosed in the embodiment of the present invention.Multiple lamp pearl 16 forms arrow, now, when the power supply of emergency light normally works, each lamp pearl 16 can as a light source, when power cut-off, fluorescent material 13 in lamp pearl 16 is luminous, and all alight pearls 16 form an arrow Warning Mark, thus achieves the emergent of emergency light and indicative function.
Because the persistence of twilight sunset powder can reach 10 hours, and brightness is higher, and can use as illumination, therefore, in the present embodiment, the fluorescent material 13 in lamp pearl 16 can be twilight sunset powder.
Wherein, all in the present embodiment lamp pearls 16 are all connected in series.
Preferably, the lamp pearl 16 in the present embodiment is SMD lamp bead series row.
It will be understood by those skilled in the art that, fluorescent material 13 and a light-emitting diode chip for backlight unit 14 can also be packaged into area source module (Chip On Board, COB) 17, area source module 17 one-tenth Warning Mark shapes are fixed on substrate 12, specifically see Fig. 3, the structural representation of another kind of emergency light disclosed in the embodiment of the present invention.Equally, when emergency light power supply normally works, area source module 17 is as a light source, and when power cut-off, the fluorescent material 13 on area source module 17 is luminous, forms an arrow Warning Mark, thus achieves the emergent of emergency light and indicative function.
Equally, the fluorescent material 13 in the present embodiment in area source module 17 can be twilight sunset powder.
Be understandable that, the substrate 12 in the various embodiments described above all can make the shape of arrow, and substrate 12 can be aluminium base material.
Wherein, the housing 11 of emergency light is plastic material.
It will be appreciated by persons skilled in the art that when fluorescent material 13 is for long afterglow powder, because the brightness of long afterglow powder is not high, and far below twilight sunset powder, therefore, be not suitable for using as encapsulation powder.Now, need to arrange light-emitting area 18 in the centre of substrate 12, then at the fluorescent material 13 being coated with into Warning Mark of light-emitting area 18, specifically see Fig. 4, the structural representation of another kind of emergency light disclosed in the embodiment of the present invention.Because the brightness of twilight sunset powder is higher, therefore, twilight sunset powder can be used in light-emitting area 18, can certainly YAG fluorescent powder be used.
