Abstract
The utility model provides a high-reliability firefighting emergency flashing identification lamp which comprises a shell, an identification plate and a red-green light-emitting diode, wherein the red-green light-emitting diode is installed on the shell. The high-reliability firefighting emergency flashing identification lamp further comprises a capacitance current-limiting rectification power supply, a master control circuit board, a flashing control module, an LED lighting module and a rechargeable battery, wherein the capacitance current-limiting rectification power supply, the master control circuit board, the flashing control module, the LED lighting module and the rechargeable battery are arranged in the shell. The capacitance current-limiting rectification power supply is used for charging the rechargeable battery through the master control circuit board and simultaneously providing electricity for the LED lighting module through the flashing control module. The high-reliability firefighting emergency flashing identification lamp has the advantages that the high-reliability firefighting emergency flashing identification lamp is simple, applicable, safe and reliable, and due to the fact that the capacitance current-limiting rectification power supply is used for replacing a switching power supply which is provided with many components and is high in voltage, the reliability is greatly improved; the service life is long, due to the fact that low-voltage direct power supply is adopted in the lighting module, a booster circuit is omitted, and due to the fact that a plurality of LEDs are connected in parallel, the fault rate is reduced greatly; energy-saving continuous display time is long, due to the fact that a flashing light-emitting mode is adopted, energy can be saved by about two thirds, and the continuous display time is prolonged by about 2 times after power failure.
Description
Technical field
The utility model relates to fire-fighting small electric apparatus, particularly a kind of high reliability fire-fighting emergent flashing index lamp.
Background technology
At all kinds of office buildings, in hotel, student dormitory, high residential building, fire-fighting emergent identification lamp can be found everywhere, as floor identification light, fire exit etc.; The fire-fighting emergent identification lamp using at present, it is mostly self-powered autonomous control type, using lighting circuit at ordinary times as working power, by its sign of high-brightness LED luminescence display, simultaneously to built-in rechargeable battery charging, when run into when external circuit has a power failure, be automatically converted to built-in rechargeable battery powered and continuity shows.This class fire-fighting emergent identification lamp user is numerous, but the short and perdurability person's of existence life-span short deficiency, be generally once the even some months having to 3 years and damage, differ greatly with the light-emitting component LED life-span of 100,000 hours, reason adopts bum components and parts except manufacturing in a rough and slipshod way, it is inner that to adopt many LED tandem workings of power supply of boosting of Switching Power Supply and low pressure are basic reasons, Switching Power Supply and the low pressure feed circuit components and parts that boost are more, voltage again high failure rate is naturally just high, as long as many LED tandem workings have a damage or the whole identification light of rosin joint also just to damage, so greatly shortened the serviceable life of identification light, this class fire-fighting emergent identification lamp can only maintain several hours after having a power failure simultaneously, and the of short duration power failure time of still dealing with is slightly grown and just performed practically no function.
Summary of the invention
The purpose of this utility model is exactly the above-mentioned deficiency that will overcome existing fire-fighting emergent identification lamp, and a kind of high reliability fire-fighting emergent flashing index lamp is provided, and saves the energy, improves reliability, greatly extends the rear continuity working time that has a power failure.
For achieving the above object, the utility model provides a kind of high reliability fire-fighting emergent flashing index lamp.
The utility model high reliability fire-fighting emergent flashing index lamp comprises housing, sign board, is arranged on the red and green color light emitting diode on housing, also comprise capacitance current-limiting rectifier power source, master control circuit board, flicker control module, LED lighting module and rechargeable battery in housing, it is characterized in that: wherein said capacitance current-limiting rectifier power source is that rechargeable battery charging is that LED lighting module is powered by flicker control module simultaneously by master control circuit board, wherein said LED lighting module adopts low pressure directly to power, and many LED are wherein parallel connections.
The utility model high reliability fire-fighting emergent flashing index lamp, in wherein said red and green color light emitting diode, emitting red light diode is automatically converted to built-in rechargeable battery powered and in continuity show state when externally circuit has a power failure as power light, green emitting diode indicating sign lamp.
Below in conjunction with embodiment, with reference to accompanying drawing, be elaborated.
Accompanying drawing explanation
Fig. 1 is the front view of the utility model high reliability fire-fighting emergent flashing index lamp;
Fig. 2 is that the utility model high reliability fire-fighting emergent flashing index lamp is removed circuit board and the module connection layout after sign board.
Embodiment
Below in conjunction with accompanying drawing, describe the embodiment of the utility model sound, light-operated fire-fighting emergent flashing index lamp in detail.
With reference to Fig. 1, Fig. 2, the utility model high reliability fire-fighting emergent flashing index lamp comprises housing 1, sign board 2, be arranged on the red and green color light emitting diode 3 on housing 1, also comprise the capacitance current-limiting rectifier power source 4 in housing 1, master control circuit board 5, flicker control module 6, LED lighting module 7 and rechargeable battery 8, it is characterized in that: wherein said capacitance current-limiting rectifier power source 4 is 7 power supplies of LED lighting module by flicker control module 6 by master control circuit board 5 for rechargeable battery 6 charges simultaneously, flicker control module 6 is controlled LED lighting module 7 and is lighted 0.3 second, extinguish 0.6 second, wherein said LED lighting module 7 adopts low pressure directly to power, and many LED are wherein parallel connections.
The utility model high reliability fire-fighting emergent flashing index lamp, in wherein said red and green color light emitting diode 3, emitting red light diode is automatically converted to 8 power supplies of built-in rechargeable battery and in continuity show state when externally circuit has a power failure as power light, green emitting diode indicating sign lamp.
Advantage and the good effect of the utility model high reliability fire-fighting emergent flashing index lamp are:
1, simply applicable safe and reliable: owing to adopting capacitance current-limiting rectifier power source to replace the Switching Power Supply that components and parts are many, voltage is high, reliability greatly improves; 2, long working life: directly power because lighting module adopts low pressure, saved the booster circuit that components and parts are many, voltage is high, so the failure rate that while many LED are parallel connections reduces greatly; 3, energy-conservation continuity displaying time is permanent: owing to adopting flashing mode, compare energy-conservation closely 2/3 with long bright formula fire-fighting emergent identification lamp, the fire-fighting emergent identification lamp of the continuity displaying time after simultaneously having a power failure and employing same capability rechargeable battery is compared and has been increased nearly 2 times.
Embodiment recited above is described the preferred embodiment of the present invention, not the spirit and scope of the present invention is limited.Do not departing under the prerequisite of design concept of the present invention; various modification and improvement that this area ordinary person makes technical scheme of the present invention; all should drop into protection scope of the present invention, the technology contents that the present invention asks for protection, is all documented in claims.
