Abstract
The utility model discloses a lamp with a back-up power supply system. The lamp with the backup power supply system is characterized by comprising a lighting lamp, a back-up power source and a relay, wherein the relay comprises a coil and a normally-closed contact, a positive electrode of the back-up power source is connected with an inlet wire L of the lighting lamp, and a negative electrode the back-up power source is connected with an outlet wire N of the lighting lamp through the normally-closed contact of the relay. According to the lamp with the backup power supply system, the back-up power source connected with the lighting lamp can be started when a circuit is opened. Therefore, the lighting lamp can keep normal lighting, daily work and life are ensured, and inconvenience in life or work caused by sudden power off is avoided.
Description
The utility model relates to a kind of lamp, especially a kind of lamp that contains the reserve electric power system.
Background technology
At present, the illuminating lamp that people use does not in daily life contain the reserve electric power system usually, if circuit cuts off the power supply suddenly, illuminating lamp can't normally keep illumination, brings inconvenience then for people's life as usual and work.
Summary of the invention
The utility model purpose: the purpose of the utility model is in order to solve the deficiency of prior art, a kind of lamp that contains the reserve electric power system to be provided.
Technical scheme: in order to realize above purpose; The described a kind of lamp that contains the reserve electric power system of the utility model comprises illuminating lamp, back-up source; Relay; Wherein relay comprises coil, normally-closed contact, and the positive pole of back-up source is connected with the inlet wire of illuminating lamp, and the negative pole of back-up source is connected with the outlet of illuminating lamp through the normally-closed contact of relay.
In order in time to use back-up source in when outage, described relay coil control normally-closed contact, the relay coil two ends respectively with L, N is connected.
For ability dual-purpose alternating current and direct current, described illuminating lamp is the AC/DC illuminating lamp.
Beneficial effect: a kind of lamp that contains the reserve electric power system is when down circuitry; Can start the back-up source that is connected with illuminating lamp; Make illuminating lamp can keep normal illumination, guarantee the carrying out of routine work life, avoid because of lose the life that illumination causes suddenly or work on inconvenience.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Wherein: 1, illuminating lamp, 2, back-up source, 3, relay, 4, normally-closed contact, 5, coil.
Embodiment
Further illustrate the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of lamp that contains the reserve electric power system comprises illuminating lamp; Back-up source, relay, wherein relay comprises coil, normally-closed contact; The L connection mutually of the positive pole of back-up source and the inlet wire of illuminating lamp, the negative pole of back-up source is through the outlet N connection mutually of the normally-closed contact and the illuminating lamp of relay, the coil control normally-closed contact of said relay; The coil two ends of relay respectively with L, N is connected, described illuminating lamp is the AC/DC illuminating lamp.
At circuit just often, the coil 5 of relay 3 produces magnetic control relay 3 under the energising situation normally-closed contact 4 is an off-state, and back-up source 2 is not supplied power; Illuminating lamp 1 uses alternating current; If circuit cuts off the power supply suddenly, the coil 5 of relay 3 loses magnetism, then normally-closed contact 4 auto-closings of relay 3; Back-up source 2 and illuminating lamp 1 generation closed-loop path, the direct current that illuminating lamp 1 uses back-up source 2 to provide keeps normal illumination.
The foregoing description only is the technical conceive and the characteristics of explanation the utility model, its objective is to let to be familiar with the also enforcement according to this of content that these those skilled in the art can understand the utility model, can not limit the protection range of the utility model with this.All equivalents or modifications of having done according to the utility model spirit all should be encompassed within the protection range of the utility model.
