Abstract
The invention discloses a warning light. The warning light comprises a warning light body, a warning claxon, a warning light switch, a capacitor, a relay contact, a coil and an iron core, wherein the warning light switch is connected with the warning light body, the delay contact is also connected with the warning light switch, the warning claxon is connected with the delay contact, the capacitor is connected with the coil, and the coil is wound on the iron core. According to the warning light, personnel are reminded of paying attention to safety through the methods of lightening the warning light and giving out intermittent warning sound and the probability of the occurrence of perilous incidents is reduced.
Description
The present invention 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
Goal of the invention: the objective of the invention is provides a kind of warning light in order to solve the deficiencies in the prior art.
Technical scheme: in order to realize above purpose, a kind of warning light of the present invention comprises warning light, the alarm electric horn, warning light switch, capacitor, relay contact, coil, iron core, described warning light switch is connected with warning light, described relay contact also is connected with the warning light switch, described alarm electric horn is connected with relay contact, described capacitor connecting coil, and described coil is wound on the iron core.
In order more significantly to show alarm, described warning light is red LED lamp.
For holding circuit is not short-circuited, also be provided with an air switch before the described warning light switch.
Beneficial effect: a kind of warning light provided by the invention, can be in time take care by the mode prompting personnel that play bright warning light and send interrupted alarm song, reduce the probability that peril takes place.
Description of drawings
Fig. 1 is structural representation of the present invention;
Wherein: 1. warning light, 2. alarm electric horn, 3. alarm contact, 4. capacitor, 5. relay contact, 6,7. coil, 8. iron core.
Embodiment
Further illustrate the present invention below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of warning light comprises warning light, the alarm electric horn, warning light switch, capacitor, relay contact, coil, iron core, described warning light switch is connected with warning light, and described relay contact also is connected with the warning light switch, and described alarm electric horn is connected with relay contact, described capacitor connecting coil, described coil is wound on the iron core, and described warning light is red LED lamp, also is provided with an air switch before the described warning light switch.
The warning light that is used for the reversing automobile alarm, warning light switch closure 3, power on circuitry, warning light bright 1, electric current makes alarm electric horn 2 send the sound, this coil 6 by alarm electric horn 2 simultaneously, also there is electric current to pass through in 7, the electric current of flowing through coil 7 is simultaneously to capacitor 4 chargings, because coil 6, sense of current is opposite in 7, and the resultant magnetic field of generation is very weak, relay contact 5 can remain closed, along with the raising of capacitor 4 charge volumes, fade away in electric current and magnetic field thereof in the 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, after relay contact 5 separated, capacitor 4 was through coil 7 and 6 discharges, and this moment, two coils produced very strong resultant magnetic field, make relay contact 5 continue separately, know that 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 scope of the present invention with this.All spirit essence has been done according to the present invention equivalents or modification all should be encompassed within protection scope of the present invention.
