Abstract
The utility model discloses an LED modulator tube with an emergency function. The LED modulator tube comprises a switching power supply circuit, an LED control circuit and an LED lamp panel. The switching power supply circuit switches mains supply 220V alternating current to direct current needed by a lighting circuit and transmits the direct current to the LED control circuit, and the LED control circuit controls opening and closing of the LED lamp panel. The switching power supply circuit further charges a battery, and the battery transmits stored electric energy to the LED control circuit. Due to the fact that the chargeable battery is additionally arranged, under the power failure condition, the LED modulator tube can use the stored electric energy for electrically driving the LED lamp panel, so that the LED modulator tube has the emergency function.
Description
Technical field:
The utility model relates to technical field of lamps, more specifically to a kind of LED fluorescent tube with emergency function.
Background technology:
In daily life, in order to deal with the situation of unexpected outage, often the building corridor in or the indoor location emergency light solve.Current mounting means is that people are installed separately normal illumination lamp and emergency light, cause emergency light only on commercial building, to use, and seldom use in the private residence the inside, have caused the inconvenience of people's daily lifes.
The utility model content:
The purpose of this utility model just is to provide a kind of LED fluorescent tube with emergency function, and it not only has the effect of normal illumination, also has the effect of emergency lighting.
For achieving the above object, a kind of LED fluorescent tube with emergency function of the present utility model, it comprises switching power circuit, LED control circuit and LED lamp plate; Described switching power circuit converts civil power 220V alternating current to lighting circuit required direct current, and this direct current is delivered to the LED control circuit, and the LED control circuit controls opening and cutting out of LED lamp plate; Described switching power circuit also charges to battery, and battery sends stored electric energy to the LED control circuit.
As technique scheme preferably, described switching power circuit charges to battery by overcharge protection circuit, overcharge protection circuit carries out monitoring and controlling to battery charging process.
The beneficial effects of the utility model are: first, the utility model is by increasing by a chargeable battery, make this LED fluorescent tube in the situation that have a power failure, can utilize the electric energy himself stored to carry out driven by power to the LED lamp plate, make this LED fluorescent tube have emergent function, when people when the mounted LED lamp pipe, are equivalent to install simultaneously an emergency light in individual house, facilitated daily life; The second, the utility model has designed overcharge protection circuit, makes it in the charging process of battery, monitor whether cell voltage is charged to standard voltage value, thereby plays the purpose of protection battery, has extended the service life of battery.
The accompanying drawing explanation:
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is functional-block diagram of the present utility model;
Fig. 2 is embodiment schematic diagram of the present utility model;
In figure: 1, switching power circuit; 2, LED control circuit; 3, LED lamp plate; 4, overcharge protection circuit; 5, battery.
The specific embodiment:
As shown in Figure 1: the LED fluorescent tube with emergency function of the present utility model, it comprises switching power circuit 1, LED control circuit 2 and LED lamp plate 3; Described switching power circuit 1 converts civil power 220V alternating current to illumination required direct current after step-down rectifier, and direct current is delivered to LED control circuit 2, and LED control circuit 2 controls opening and cutting out of LED lamp plate; Described switching power circuit 1 also charges to battery 5; described switching power circuit 1 charges for battery 5 by overcharge protection circuit 4; the charging process of 4 pairs of batteries 5 of overcharge protection circuit is carried out monitoring and controlling, and battery 5 sends stored electric energy to LED control circuit 2.
As shown in Figure 2, be preferred embodiment of the present utility model, in the present embodiment, adopt BP3122 to do the constant-current driven chip of LED lamp plate, adopt the charging management chip of CX9059 as battery.The utility model is during as the general lighting lamp, civil power 220V alternating current is after D1 to D4 rectification, deliver to power pins the 3rd and the 2nd pin of chip BP3122, when the 3rd pin voltage is opened threshold values along with the continuous charging of capacitor C 2 rises to chip, chip BP3122 starts working, and by the T1 voltage pulse output, this pulse voltage converts the required DC voltage of lamp plate to after the D5 rectification, deliver to LED lamp plate circuit, drive WLED it is lighted; Simultaneously, DC voltage after the D5 rectification is also delivered to power pins the 4th and the 2nd pin of chip CX9059 and is the battery charging by resistance R 6, described chip CX9059 is by the charging voltage of the 3rd pin and the 6th pin monitoring battery, to prevent overcharging of battery, when the utility model is used as emergency light, by the direct driving LED lamp plate of battery circuit, and light WLED.
The foregoing is only and embody preferred embodiment of the present utility model, therefore do not limit protection domain of the present utility model, every equalization of doing according to the utility model change with modify and all belong to the scope of the claims that the utility model contains within.
