Abstract
The utility model discloses an emergency lamp, which includes a lamp housing, wherein an overcharging and overdischarging protection circuit, a battery, a circuit board, and a charging DC (direct current) directional diode are mounted in the lamp housing; at least one LED lamp is mounted on the bottom surface of the circuit board; the overcharging and overdischarging protection circuit is connected with the battery, the LED lamp, the charging DC directional diode and an external DC power supply respectively; a current-limiting resistor is arranged between the overcharging and overdischarging protection circuit and the LED lamp; and the overcharging and overdischarging protection circuit and the battery are in close fit. The emergency lamp has the advantages of simple structure, long power supply time in emergency, and the like.
Description
Technical field
The utility model relates to a kind of lamp, and more particularly, it relates to a kind of emergency light.
Background technology
At present, lamp & lantern equipment need more fixing civil power etc. supply power just can guarantee normally luminous.Therefore, in some special occasions, if outage suddenly promptly can cause confusion etc.Therefore, how emergent lamp & lantern is provided, becomes problem demanding prompt solution.
The utility model content
The utility model technical problem to be solved provides long emergency light of a kind of simple in structure, emergency service time.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of emergency light; It comprises lamp housing; In said lamp housing, be equipped with and overcharge and over circuit, battery, circuit board, the directed diode of charging direct current; In said circuit board bottom surface at least one LED lamp is installed, described overcharging with the over circuit joined with battery, LED lamp, the directed diode of charging direct current and extraneous dc source respectively, said overcharge and over circuit and LED lamp between be provided with current-limiting resistance; And, said overcharging and over circuit and said battery tight fit.
Said lamp housing is made up of the lamp body on top and the clear lamp of lower part, and described overcharging with over circuit, battery, circuit board, the directed diode of charging direct current, current-limiting resistance is positioned at lamp body, and said LED lamp is positioned at clear lamp.
The utility model is owing to having adopted said structure, so it has following beneficial effect:
In the utility model; Overcharge and over circuit, battery, circuit board, the directed diode of charging direct current through in said lamp housing, being equipped with; In said circuit board bottom surface at least one LED lamp is installed; Described overcharging with the over circuit joined with battery, LED lamp, the directed diode of charging direct current and extraneous dc source respectively; Between super-charge super-discharge holding circuit and LED, be provided with current-limiting resistance, and this overcharges and over circuit and said battery tight fit.Therefore, give the power supply of LED lamp through battery and because LED lamp power consumption is few, therefore, good result and its power-on time that the utility model plays emergency service are long, generally can keep more than 3 hours.In addition, the utility model is simple in structure, and its processing and manufacturing is easy, is prone to form produce in batches.
After the detailed description of the embodiment that combines advantages the utility model, it is clearer that characteristics of the utility model and advantage will become.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the utility model;
Fig. 2 is the sectional view of lamp housing part;
Fig. 3 is the block diagram of the partial circuit of the utility model.
The specific embodiment
With an embodiment the utility model is done further detailed explanation below, but should explain that the protection domain of the utility model is not limited only to this.
Consult Fig. 1 to Fig. 3, a kind of emergency light, it comprises lamp housing 2, in said lamp housing 2, is equipped with to overcharge and over circuit 5, battery 6, circuit board 7, the directed diode 9 of charging direct current.At least one LED lamp 8 and current-limiting resistance 11 are installed in said circuit board 7 bottom surfaces, and wherein the quantity of LED lamp 8 can be 2,8,10 or the like the protection domains that do not influence the utility model.Described overcharging with over circuit 5 joined with battery 6, LED lamp 8, the directed diode 9 of charging direct current and extraneous dc source 10 respectively; Said current-limiting resistance 11 be arranged on said overcharge and over circuit 5 and LED lamp 8 between; And this overcharges and over circuit 5 and said battery 6 tight fits.Specifically, give in LED lamp 8 power supply process, give the 8 luminous work of LED lamp when change the dc source 10 that is obtained behind the direct current through civil power; At this moment; Because overcharge the effect with over circuit 5, thus the electric energy that battery 6 avoid waste battery 6 need not for 8 power supplies of LED lamp, and; At this moment, battery 6 also can be in charging.The directed diode 9 of charging direct current can prevent that electric current from producing reverse impact to charger or solar energy photovoltaic panel.In addition, can realize the on and off of LED lamp 8 through gauge tap 1.
In this embodiment; Said lamp housing 2 is made up of the lamp body 3 on top and the clear lamp 4 of lower part; Described overcharging with over circuit 5, battery 6, circuit board 7, the directed diode 9 of charging direct current, current-limiting resistance 11 is positioned at lamp body 3, and said LED lamp 8 is positioned at clear lamp 4.
Though described the embodiment of the utility model in conjunction with accompanying drawing; But those skilled in the art can make various distortion or modification within the scope of the appended claims; As long as be no more than the described protection domain of the claim of the utility model, all should be within the protection domain of the utility model.
