Description
Technical field
The present invention relates to be used in the light source in fixedly alarm or the indicator signal device.Especially, the present invention relates to be used in light source in the trapped orbit signalling means.
Background technology
The trapped orbit signalling means is used for information is passed to train driver, for example, and along whether advance safety or whether particular course has been set of a certain rail.Usually the form with different " demonstration " passes to train driver with information, and described " demonstration " is the various combination and the layout of the lampion in the fixed signal device.
When using in the text, term " fixed signal device " refers to its position signalling means fixing with respect to ground.Suitably fixedly the sort signal device is in order to prevent the motion of signalling means with respect to ground, the especially aligning of this signalling means or orientation.Therefore, for example, the trapped orbit signalling means can be installed on pillar or the gantry (gantry), and described pillar or gantry are attached to ground.Certainly, in the situation of track signal device, this is basic, so that security information is passed to train driver reliably.
The example of the such trapped orbit signalling means that relates to as the application, can discern the track signal device of two kinds of particular types: the position light signal device (also is called the ground location lamp, GPL) is usually located on the ground and is used in the zone such as by-track and maintenance area; And lampion signalling means (CLS---also be called the multi-color cord signalling means) is located immediately on the trunk railway usually or is positioned at the main line top and is positioned at a side of main line.CLS is commonly used to control the traffic flow along one or more rail of trunk railway.
In Britain, treat to meet rail track standard RT/E/S/10062 (current publication in August, 1,1999) as all track signal devices of CLS.This standard has especially been listed the lowest term of reliability, color and observability.In other country (for example China), also there is the similar standard that is used for the track signal device.
The many track signal devices that use all use osram lamp as light source at present.Yet led light source (that is, comprising the light source of a plurality of LED) is because its various advantages are used just more and more, and people recognize that led light source will replace osram lamp.For example, it has been generally acknowledged that led light source is more more reliable than osram lamp.
Most of rail networks utilize condition monitoring system to monitor the state of the light source of trapped orbit signalling means.Typical condition monitoring system comprises condition monitoring device and many conducting wires that are used for described condition monitoring device is connected with the light source of trapped orbit signalling means.Each light source comprises and is used for and will be passed to the telecommunication circuit of condition monitoring system about the information of light source state (for example, when in the light source fault being arranged with the form of alarm signal).Sometimes, this telecommunication circuit is called as " inspection " circuit.
In use, the telecommunication circuit of light source is connected with the conducting wire of condition monitoring system, thereby the telecommunication circuit of light source can be passed to condition monitoring system with the information about the light source state.Therefore, if break down in the light source, this information can be passed to condition monitoring device, thereby, can send the slip-stick artist to keep in repair light source.
The inventor observes, with track foundation facility that the trapped orbit signalling means typically is connected in voltge surge can appear.For example, may be because supply voltage impact, high induction line voltage or thunderbolt cause voltge surge, and voltge surge can damage the trapped orbit signalling means, if especially voltge surge is bigger.If damaged, so, for example keeping in repair the fixed signal device by the light source of changing damage can be very expensive and consuming time.
Though rare relatively in some countries, other country (for example, China), the situation of being struck by lightning on the track foundation facility may be frequent relatively.Owing to comprise big voltage, the single thunderbolt just can cause many trapped orbit signalling means to damage.

As can seeing from Fig. 3, housing 220 at the thickness at transparent window 224 places less than the thickness of housing 220 on the either side of transparent window 224.This helps light to arrive the photodetector of receiving element 260 from LED240.
Fig. 4 shows fixed signal equipment 300, the condition monitoring system 350 that it comprises light source 301 (output light 302) and is used for the information that receives from light source 301.Condition monitoring system 350 comprises receiving element 360, conducting wire 370 and condition monitoring device 380.In use, the telecommunication circuit of the receiving circuit of receiving element 360 and light source 301 is electrically isolated from one, thereby makes the telecommunication circuit (in fact, being the inside of the housing of light source 301) of light source 301 and condition monitoring system electricity isolate.
As shown in Figure 4, for the sake of clarity, receiving element 360 is not attached to light source 301.Yet in use, receiving element 360 will be connected with light source 301.
In the time of in being used in this instructions and claims, term " comprises " and " comprising " and modification thereof are represented, includes special characteristic, step or integral body.This terminological interpretation is not eliminating further feature, step or whole existence.
At foregoing description (or in following claim, or at accompanying drawing) in disclosed, that express with its particular form or carry out the device of disclosed function or be used to obtain disclosed result's the method or the feature of processing according to being used to, as suitable, realize the present invention with its various forms discriminably or so that any combination of this feature is next.
