Abstract
The utility model discloses a warning lamp, comprising a lamp body, a warning electric horn, a warning lamp switch, a capacitor, a relay contact, a coil and an iron core. The warning lamp switch is connected with the lamp body. The relay contact is also connected with the warning lamp body. The warning electric horn is connected with the relay contact. The capacitor is connected with the coil, which is wounded on the iron core. The warning lamp of the utility model can be turned on to warn people to exercise caution by giving continuous warning sounds, thereby reducing the dangerous occurrence.
Description
Technical field
The utility model relates to a kind of warning light.
Background technology
In daily life, people often cause the loss of personal safety as well as the property safety because in time do not notice hydropac.
Summary of the invention
The utility model purpose: the purpose of this utility model is in order to solve the deficiencies in the prior art, a kind of warning light to be provided.
Technical scheme: in order to realize above purpose, a kind of warning light described in the utility model comprises lamp body, the alarm electric horn, warning light switch, capacitor, relay contact, the first coil, the second coil, iron core, described warning light switch is connected with lamp body, and described relay contact also is connected with the warning light switch, described alarm electric horn is connected with relay contact, described capacitor connects the second coil, described the first coil, and the second coil winding is on iron core.
Described lamp body is red LED lamp.
Also be provided with an air switch before the described lamp body switch.
Beneficial effect: a kind of warning light that the utility model provides, can be in time take care by the mode prompting personnel that beat the bright light body and send interrupted alarm song, reduce the probability that peril occurs.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Wherein: 1. lamp body, 2. alarm electric horn, 3. warning light switch, 4. capacitor, 5. relay contact, 6. the first coil, 7. the second coil, 8. iron core, 9. air switch.
Embodiment
Further illustrate the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of warning light, comprise lamp body 1, alarm electric horn 2, warning light switch 3, capacitor 4, relay contact 5, the first coil 6, the second coil 7, iron core 8, described warning light switch 3 is connected with lamp body 1, described relay contact 5 also is connected with warning light switch 3, described alarm electric horn 2 is connected with relay contact 5, and described capacitor 4 connects the second coil, and described the first coil 6 and the second coil 7 are wound on unshakable in one's determination 8, described lamp body 1 is red LED lamp, also is provided with an air switch 9 before the described warning light switch 3.
The warning light that is used for the reversing automobile alarm, warning light switch 3 closures, power on circuitry, lamp body 1 is bright, electric current is by alarm electric horn 2 simultaneously, make alarm electric horn 2 send the sound, at this moment the first coil 6, also there is electric current to pass through in the second coil 7, the electric current of flowing through coil 7 is simultaneously to capacitor 4 chargings, because the first coil 6, sense of current is opposite in the second coil 7, the resultant magnetic field that produces is very weak, relay contact 5 can remain closed, raising along with capacitor 4 charge volumes, fade away in electric current and magnetic field thereof in the second coil 7, when the resultant magnetic field is increased to when being enough to relay contact 5 separately, alarm electric horn 2 cuts off the power supply and stops sounding, and after relay contact 5 separated, capacitor 4 was through the first coil 6,7 discharges of the second coil, this moment, two coils produced very strong resultant magnetic field, so that relay contact 5 continuation separately, until capacitor 4 discharge currents disappear substantially, relay contact 5 is closure and alarm electric horn 2 heavy sounding again, so repeatedly, alarm electric horn 2 just intermittently gives the alarm, and causes pedestrian and vehicle drive personnel's vigilance.
Implement according to this, can not limit protection domain of the present utility model with this.All equivalents or modifications of having done according to the utility model Spirit Essence all should be encompassed within the protection domain of the present utility model.
