Abstract
The invention relates to an optical signaling device, in particular for railway safety equipment, comprising an electronic component (2) and a power dissipation device (8) for converting electrical power into thermal energy, wherein the electronic component (2) is arranged in a signal generator housing (1) which is connected to a screen (4) for reducing ghost light. In order to avoid thermal loading of the electronic component (2), it is provided that the power dissipation device is arranged on the screen (4).
Description
The present invention relates to a kind of optical signal equipment, particularly for railway security equipment, the optical signal equipment has electronics
Device and the power dissipation devices for electrical power to be converted into heat energy, wherein electronic device are arranged on signal generator housing
In, the signal generator housing is connected with the shield for reducing ghost light.
Explanation is primarily related in the related traffic route of track set for showing the optical signal of signal implication below
It is standby, but technical scheme claimed is not limited to this application.On the contrary be used for various signals control traffic route with
And the application in industrial circle can consider.
In principle, optical signal equipment is used as signal generator or symbol display, the shifting that optical signal equipment passes through light-emitting area
The information that dynamic and/or moulding (namely by luminescence feature) transmission is determined.What it was often referred to herein is that security is related
Information, described information does not allow visually to malfunction or hands over mixed by external light.(it is, for example, sunshine or big by ambient light
Lamp wiring) injection caused by, the undesirable flicker of luminous point or error be referred to as phantom or illusion.In order to suppress phantom
Light, extension, the so-called shield of the signal generator housing of optical signal equipment equally with cap-shaped.
Optical signal equipment is often necessary to the input power for ensureing to determine for compatibility reasons.If the input power
When not needing actually, such as in LED signal generator, then additional customer is needed for power adaptation, it will be surplus
Complementary work rate is converted into heat energy.
Known power dissipation devices are made up of the resistance being assemblied in signal generator housing in cooling body.For reality
Insulation attribute the need for existing circuit, it is several millimeters that resistance, which must be connected to the minimum spacing of other devices,.Except this
Outside spacing, major defect is the heat in signal generator housing.
This heat has a negative impact further for degeneration, that is, electronic device, such as LED ageing process.
In order to realize more preferable radiating, by power dissipation devices as known to GB2390669A and DE102011084166A1
It is transferred in housing wall.It is lens bracket configuration power dissipation devices according to DE102012205052A1.
In these embodiments, at least a portion heat energy can enter enclosure interior, and thus electronic device can aggravate to degenerate ground
It is heated.
The technical problems to be solved by the invention are, eliminate the shortcoming and provide the optical signal equipment of this type,
Wherein electronic device is avoided to be heated by power dissipation devices.
The technical problem is so solved according to of the invention, i.e. power dissipation equipment distributes to shield.
In this way, net quantity of heat is discharged caused by the too high input power of optical signal equipment.Cause
This can cancel the cooling body added in enclosure interior.Thus the fitting depth of signal generator housing can reduce.In cooling
The pitch problems of power resistor on body no longer exist in the layout according to the power dissipation devices of the present invention.Thus can be with
Cancel the assembling of the consuming of resistance.The cost of cooling body and the particularly accurate assembling of resistance are removed.Using compact signal
It is particularly advantageous that the heated of electronic device is avoided during shield (Kompaktsignalschirm).
Cooling can be carried out by the cofree air-flow of shield circumferential surface.Existing shield is used as cooling
Body, therefore cost can be reduced.The shield and signal generator are made up of less device, and they are jointly assemblied in tightly
Gather in signal shield.Signal shield and signal generator are all without by the power dissipation devices heating of shield side.
Provided according to claim 2, shield is made up of heat-barrier material.Thus signal generator housing and it is located therein
Electronic device can further avoid hot loading.
According to claim 3, especially plate material of screening is used as using plastics.Usual shield is made up of metal material, but
It is that it has poor thermal insulation.Plastics shield is also significantly lighter and more cheap relative to the form of implementation of metal.
According to claim 4, power dissipation devices are designed as heating apparatus of screening.By to the deliberate heating of shield
It can prevent it from being damaged by snow and ice.
Here, according to claim 5, heating apparatus of screening is preferably designed for being embedded in the top area on the top of protective plate
In heating element heater.Thus power dissipation requirement and deicing requirements are largely combined.
Hereinafter, the present invention is elaborated with reference to accompanying drawing.Accompanying drawing shows the schematic diagram of optical signal equipment with longtitudinal view.
Optical signal equipment is main by signal generator housing 1 (being used to accommodate electronic device) and lens devices 3 and top cover
The shield 4 and stable compact signal shield 5 that are used to reduce ghost light of shape.Electronic device 2 in signal generator housing 1
Include the LED for emitting beam and its controlled signal generator electrical equipment.
In order that the main member of optical signal equipment can be used as the substitutes of other forms of implementation, there is provided input work
Rate, it is actually needed beyond the electronic device in shown form of implementation.In consideration of it, unwanted power passes through power dissipation
Device is converted into heat energy.The power dissipation devices are arranged in shield 4 in the form of board heating apparatus 7 of screening.Thus power
Dissipation device is used for the autotelic heating of shield simultaneously, and the thus weather influence in winter is reduced.Screen board heating apparatus 7
The whole of heat is disposed to surrounding air.In order that screen the relative communication signal 6 of board heating apparatus 7 and signal generator housing 1
It is thermally isolated as efficiently as possible with electronic device 2, then shield 4 is designed to plastics shield.
The feature of shown optical signal equipment first consists in avoid the aggravation of electronic device 2 from degenerating heated and simple
With section space-efficient structure type.
