Abstract
The utility model requests to protect a LED signal lamp monitoring device comprising a tamper-proof shield, a photosensor element, a photosensitivity detecting circuit and a warning circuit and device. Inside the tamper-proof shield is a through-hole with a single LED lamp provided in, and the through-hole is flared for light source divergent. Also inside the tamper-proof shield a photosensor element is equipped on the side of the single LED lamp to induce the single LED lamp beam. The photosensor element obtains the power source from the previous the power source of the LED signal lamp, connects to the photosensitivity detecting circuit and a warning circuit and device with the low electric level output side. The device utilizes the way of optical sensing to response the working condition of the LED lamp accurately and reliably, gives an alarm reliably in time when a fault occurs, and the device is especially applicable for mounting on railway signal lamps.
Description
Technical field
The utility model relates to a kind of LED signal lamp monitoring device.
Background technology
Traditional signal lamp is replaced by LED novel light-emitting diode signal lamp at present, in some special application, on railway traffic, signal lamp is had high reliability requirement, requires when breaking down in time to report to the police reliably.Alarm method in the past is to adopt the size of current of monitoring light-emitting diode to realize, has promptly detected electric current by testing circuit, represents that promptly signal lamp is working properly, and it is undesired that no current is promptly worked.The drawback that this mode exists is that monitoring is inaccurate, because be not that open circuit but short circuit or half short circuit might make electric current change not quite even and change when light-emitting diode damages sometimes, causes testing circuit to do the judgement that makes mistake, and therefore brings potential safety hazard.
Summary of the invention:
The utility model purpose is to provide a kind of LED signal lamp monitoring device at the deficiency of existing signal lamp monitoring mode existence, has adopted the light sensing mode, reflects the working condition of LED lamp accurately and reliably.
The technical solution of the utility model is:
A kind of LED signal lamp monitoring device includes anti-tampering radome, light-sensitive element, photosensitive detection circuit and warning circuit and device is formed, and the through hole of the single lamp of ccontaining LED is arranged in the anti-tampering radome, and the anterior flare of through hole is convenient to light source and is dispersed.In anti-tampering radome, be provided with light-sensitive element, be positioned at the light of the single lamp side of LED direct induction LED list lamp.Light-sensitive element obtains power supply from the original power supply of LED signal lamp, connects photoelectric detective circuit and warning circuit and device at its low level output.
This device operation principle:
As LED lamp D
1When luminous, light-sensitive element T
1Conducting, its Vout end output low level is detected by photoelectric detective circuit, expression LED lamp D
1Luminous normal.
As LED lamp D
1Damage, luminous when very little or not luminous, light-sensitive element T
1End, Vout end output high level is detected by photoelectric detective circuit, sends sound and light alarm by warning circuit, expression D
1Luminous undesired.
The utility model has the advantages that:
1, owing to adopted the light sensing mode, with optical sensor having or not from the side induction light of LED lamp, no matter thereby its operating current size, can both reflect that exactly whether luminous it is, can in time report to the police reliably when breaking down, can improve LED signal lamp safety in utilization greatly, not influence the demonstration of original signal light simultaneously, do not increase former power supply power consumption, be specially adapted to be installed on the railway signal lamp.
2, adopt custom-designed anti-tampering radome, neither influence forward light and penetrate, shielded the veiling glare that other direction is come again, realize that anti-veiling glare disturbs, and does not influence LED lamp operate as normal.
3, this device is not that dead ahead (normal direction) from the LED lamp measures light signal, is used for monitoring but get light from the side direction of LED lamp, can not too influence the LED lamp like this and realize monitoring its working condition as the basic function of signal lamp.
4, cost is low, reliability is high, and device is not had specific (special) requirements, even this circuit breaks down, does not also influence the work of original signal lamp.
Description of drawings
Fig. 1 is the structural representation of this device;
Fig. 2 is the electrical schematic diagram of this device.
Embodiment
Referring to Fig. 1, this LED signal lamp monitoring device has the through hole 1 of the single lamp 3 of ccontaining LED, through hole 1 anterior flare mainly by anti-tampering radome 2, light-sensitive element 4, photosensitive detection circuit 8 and warning circuit and install 9 and form in the anti-tampering radome 2.Light-sensitive element 4 is arranged in the anti-tampering radome 2, and is positioned at the single lamp of LED 3 sides, directly the light of induction LED list lamp but shielded other veiling glare by radome.The pin 5 of the single lamp 3 of light-sensitive element 4 and LED with 7 when mounted with corresponding connection of pin on the wiring board.The bottom of anti-tampering radome is useful on the pin 6 that installs and fixes.What show among the figure is the example of the single lamp of a LED.
The electrical connection of this device is seen Fig. 2: light-sensitive element 4 (T
1) obtain power supply from the original power supply of LED signal lamp, as shown in the figure with the single lamp 3 (D of LED
1) be relation in parallel, be independent of each other mutually.Light-sensitive element 4 (T
1) the low level output connect photoelectric detective circuit 8 and warning circuit and install 9.
Claims (2)
1, a kind of LED signal lamp monitoring device, it is characterized in that forming by anti-tampering radome, light-sensitive element, photosensitive detection circuit and warning circuit and device, the through hole that the single lamp of ccontaining LED is arranged in the anti-tampering radome, light-sensitive element is arranged in the anti-tampering radome, and be positioned at the light of the single lamp side of LED direct induction LED list lamp, light-sensitive element obtains power supply from the original power supply of LED signal lamp, and the low level output of light-sensitive element connects photoelectric detective circuit and warning circuit and device.
2, LED signal lamp monitoring device according to claim 1 is characterized in that the anterior flare of the through hole of the single lamp of ccontaining LED.
