Abstract
The utility model discloses an LED lamp with a lighting function and a fire emergency lighting function. The LED lamp comprises a switch power supply which is connected with a mains supply. The switch power supply is connected with an LED light source. The mains supply is also connected with a mains supply detection circuit which is connected with a battery charging and discharging circuit. The battery charging and discharging circuit is connected with a storage battery and also is connected with the switch power supply and the LED light source respectively. The LED lamp is equipped with a conventional lighting function and a fire emergency lighting function, when the power supply is supplied by the mains supply in normal times, the lighting or extinguishing of the LED lamp is realized through a mains supply control switch; when the mains supply is failed or voltage is lower than working voltage of the LED lamp, the storage battery is discharged, the power supply is supplied to the LED lamp to light the LED lamp, and the emergency lighting function of the LED lamp can be maintained for 90 minutes.
Description
Technical field
The utility model relates to a kind of LED lamp, relates in particular to a kind of LED lamp with illumination functions and fire-fighting emergency illumination function.
Background technology
Employed LED lamp generally all is the single illumination work that possesses on the market at present, just the light fixture as conventional illumination functions uses, in case power supply disconnects or when being lower than operating voltage, the LED lantern festival is extinguished or brightness weakens to some extent, fails to possess the function of emergency lighting.Although, the existing function that the standby Emergency Light of a small amount of LED light fixture occurred on the market, this type of LED lamp all is to use as Delayed illumination, its LED lamp is when power-off, the brightness of illumination weakens to some extent, and brightness deterioration is must be large and its lighting hours is shorter, is generally below ten minutes.Therefore, the use of above-mentioned existing LED lamp aspect emergency lighting also is not very perfect, and this technology is still waiting to improve.
Summary of the invention
The utility model is in order to overcome the defective of prior art, purpose is to provide the LED lamp of a kind of illumination commonly used and fire-fighting emergency illumination combination, and this LED lamp is applicable to each lighting fields such as office building, market, supermarket, school, hospital, hotel, parking lot, Urban Underground Passage, factory floor, municipal works, family.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of LED lamp with illumination functions and fire-fighting emergency illumination function, comprise the Switching Power Supply that connects civil power, and described Switching Power Supply is connected with led light source; Described civil power also is connected with city's power detection circuit, and city's power detection circuit is connected with the battery charging and discharging loop, and the battery charging and discharging loop is connected with storage battery; Described battery charging and discharging loop also is connected respectively with Switching Power Supply and led light source.
Further, described battery charging and discharging loop also is connected with indication-detection button.
Further, also be provided with city's electric control switch between described civil power and the Switching Power Supply.
Further, described led light source is LED lamp pearl group.
When LED lamp of the present utility model uses as illumination functions, when city's electric control switch is opened, Switching Power Supply is powered make its illumination to the LED lamp, charge a battery simultaneously; When closing city's electric control switch, Switching Power Supply stops to the power supply of LED lamp, and the LED lamp extinguishes.City's power detection circuit detects civil power simultaneously, in case civil power outage or when being lower than this LED light working voltage, battery discharging, and make its illumination for the LED lamp provides power supply, the LED lamp plays the Emergency Light effect, and this LED lamp can be kept more than 90 minutes when emergency lighting function.
In sum, the standby conventional illumination functions of LED light fixture of the present utility model and fire-fighting emergency illumination function.When this LED lamp cuts off the power supply or is lower than operating voltage at civil power, battery discharging, and for the LED lamp provides power supply it is lighted, the LED lamp plays the Emergency Light effect, this LED lamp can reach 90 minutes when Emergency Light, and this LED light fixture has self-checking function and the self-check programs such as monthly test, annual test, meets the GB17945-2010 standard.This LED lamp is applicable to each lighting fields such as office building, market, supermarket, school, hospital, hotel, parking lot, Urban Underground Passage, factory floor, municipal works, family.

Embodiment
Embodiment 1
The utility model embodiment 1 described a kind of LED lamp with illumination functions and fire-fighting emergency illumination function as shown in Figure 1 and Figure 2, comprises the Switching Power Supply 2 that connects civil power 1, and described Switching Power Supply is connected with led light source 3; Described civil power also is connected with city's power detection circuit 4, and city's power detection circuit is connected with battery charging and discharging loop 5, and the battery charging and discharging loop is connected with storage battery 6; Described battery charging and discharging loop also is connected respectively with Switching Power Supply and led light source.
Further, described battery charging and discharging loop also is connected with indication-detection button 7.
Further, also be provided with city's electric control switch 8 between described civil power and the Switching Power Supply.
Further, described led light source is LED lamp pearl group.
When LED lamp of the present utility model uses as illumination functions, when city's electric control switch is opened, Switching Power Supply is powered make its illumination to the LED lamp, charge a battery simultaneously; When closing city's electric control switch, Switching Power Supply stops to the power supply of LED lamp, and the LED lamp extinguishes.City's power detection circuit detects civil power simultaneously, in case civil power outage or when being lower than this LED light working voltage, battery discharging, and make its illumination for the LED lamp provides power supply, the LED lamp plays the Emergency Light effect, and this LED lamp can be kept more than 90 minutes when emergency lighting function.
The above only is preferred embodiment of the present utility model, is not technology contents of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment does.
