Definitions
- the utility model relates to a lighting fixture, in particular to an LED emergency lamp for emergency lighting in public aisles, corridors and the like.
- the existing LED emergency light is mainly composed of a box body, an LED lighting device, a circuit board assembly and a battery.
- the circuit board assembly has a charging circuit, and the battery is connected to the output end of the charging circuit.
- This type of LED emergency light is equipped with a battery capacity that is usually designed to double the ignition time required by the fire protection.
- the charging circuit charges the battery.
- the power output from the battery is used to make the lighting device.
- the LED continues to illuminate, however, when the grid power outage expires, for example, more than 3 hours, the stored energy of the battery will be exhausted, the lighting device will be dimly lit, and normal lighting will not be maintained, resulting in dim and unsafe in public places.
- the object of the present invention is to provide an LED emergency light that can quickly restore normal lighting when the emergency lighting timeout causes the lighting to be abnormal.
- an LED emergency light comprising a box body, an LED lighting device, a circuit board assembly and a rechargeable battery
- the box body has a battery compartment and a drawer structure in the battery compartment a battery case, two sides of the battery compartment respectively have two elastic poles connected to the circuit board assembly, and two outer sides of the battery compartment have two electrodes corresponding to the two elastic poles of the battery compartment respectively.
- Each of the electrodes in the battery case is in close contact with a corresponding elastic pole on the battery compartment to form an electrical connection, and the two touch electrodes are respectively connected to the positive electrode and the negative electrode of the rechargeable battery in the battery case;
- the snap button is on the side of the window.
- a battery compartment having a drawer structure is provided in the battery compartment which is provided with a cover and a box which can be easily opened on the casing, it is convenient to take out the battery compartment from the casing, and the battery compartment is
- the rechargeable battery with depleted energy is replaced with a rechargeable battery with sufficient electric energy, so that the emergency lighting caused by the long power outage time of the power grid can be quickly eliminated.
- Barrier If a battery with sufficient power is installed in the spare battery box in advance, the time for eliminating abnormal lighting failure can be greatly shortened.
- the rechargeable battery uses multiple AA5 NiMH batteries or lithium batteries in series, which is better because the AA5 rechargeable battery has the same shape as the ordinary AA5 dry battery.
- the window hole and the cover plate are located on the side of the box body.
- the cover plate is facing downward, so when the battery needs to be replaced, the emergency light hanging on the wall can be directly replaced. It is not necessary to remove the emergency light from the wall, and the time to eliminate the abnormal malfunction of the emergency lighting is further shortened.
- FIG. 1 is a schematic view showing the outer structure of the LED emergency light of the present invention.
- Fig. 2 is a cross-sectional view taken along line A-A of Fig. 1;
- Figure 3 is a schematic view of the operation of replacing the battery case.
- the LED emergency light includes a box body 1, an LED lighting device 2 including a plurality of LEDs, a reflector and a transparent protective cover, and includes a rectifying and filtering circuit, a charging circuit, and a light control circuit.
- the circuit board assembly 3 and the rechargeable battery 7 are constructed.
- the casing 1 has a battery compartment 5, and two elastic poles 8 and 9 are respectively formed on the two sides of the battery compartment by brass sheets, and the two elastic poles 8 And 9 are connected to the circuit board assembly 3, and a battery case 6 similar to the drawer structure is slidable in the battery compartment 5, and the battery case 6 has the battery compartment 6 on both outer sides thereof.
- Two electrodes 13 and 14 respectively corresponding to the two elastic poles 8 and 9, each of the electrodes 13 or 14 is in close contact with the corresponding elastic pole 8 or 9 on the battery compartment 5 to form an electrical connection, and the two electrodes 13 and 13 14 is respectively associated with the positive electrode of the rechargeable battery 7 in the battery case 6.
- the negative electrode is connected, and the rechargeable battery 7 is three serially connected AA5 nickel-hydrogen batteries, and can also be connected in series with AA5 lithium battery or nickel-cadmium battery.
- the cover plate 12 and the box body 1 are connected by a hinge 15 away from the axis of the hinge 15
- On the side of the cover 12 is a buckle 12 which is stuck on the side of the window opening 11. This buckle is a kind of clip which is widely used at present. This structure makes the opening and closing of the cover 10 convenient and time-saving.
- the mains When used, when the grid has electricity and the ambient light is dark, the mains is charged by the rectifying and filtering circuit in the circuit board assembly, the charging circuit charges the rechargeable battery, and the lighting device is illuminated by the light control circuit; When the rechargeable battery outputs electric energy, the lighting device continues to illuminate the illumination through the light control circuit; when the power failure of the power grid expires, for example, more than 3 hours, the electric energy of the rechargeable battery 7 is insufficiently consumed due to excessive consumption of the LED in the lighting device.
- the cover 10 of the LED emergency light can be opened, the battery case 6 can be taken out, the rechargeable battery 7 with insufficient electric energy can be removed, and the spare rechargeable battery with sufficient electric energy can be replaced. Or ordinary dry battery, or replace it with a spare battery box with a new battery in advance, which greatly shortens the time of emergency lighting interruption, and is convenient for people's life and activities.
