Description
Technical field
This utility model is related to a kind of light-emitting device for rail vehicle, and the light-emitting device has setting in the housing
LED area (Leuchtdiodenfeld) and closing housing open side cap, the cap is for by lighting
The light radiation that diode area is produced is transparent.
Background technology
It is known in the art that this light-emitting device, more precisely, such as Deutsche Bahn's product line
The light-emitting device of the light rail of ET430 types.This light-emitting device has LED area, the LED area by
It is placed on case inside in screw.For that purpose it is necessary to arrange drilling in the circuit board of LED area so that circuit board
Can be fixed on housing.Contact between circuit board and housing is also thus important so that by light emitting diode
The operation in region and the heat that occurs are exported in housing.For this purpose, housing is typically metal.Answering in rail vehicle
With in field, housing is present usually as extrudate, exists especially as the extrudate being made up of aluminum.
On the whole, LED area this kind of fixation in the housing is considered to be consuming.Additionally, light emitting diode
Region fixation of pointwise effect on housing has the property that：Occur from light-emitting diodes area under control substantially only in these positions
The heat derives that domain is entered in housing.
Utility model content
As starting point, this utility model is based on following purpose：Further research and development start to refer to for rail vehicle
Light-emitting device so that while easily operated fixation of the LED area on housing can be realized, but also provide
Good derivation characteristic.
The purpose is realized in light-emitting device in the following way：Housing is constituted elongatedly and is had generally U-shaped in cross-section
Cross section, wherein LED area be arranged on the side opposite with open side of housing and by means of formed lid
Portion, elongated spring chuck presses to the housing.
By means of elongated spring chuck, now not only point by point but also will be luminous on the larger section along housing
Diode area is pressed on housing so that obtain favourable thermal conduction characteristic.Furthermore it is possible to abandon in the prior art commonly use
For fixing the screw connection of purpose.Thus simplify the installation of light-emitting device, for example simplified light-emitting device is in rail vehicle
Install.
Fixture can be manufactured by resilient plastic material and is supported on housing.For example, housing can be opened wide at which
There are on side guide protrusions, fixture to be supported in the guide protrusions.Can be realized by the elasticity of fixture：By light emitting diode
Region is pressed on the side opposite with the open side of U-shaped housing.
Fixture can stretch on arc ground in the housing, and in its following section press to LED area, the portion
The open side of section shrinking away from theshell body is farthest.In this embodiment, while causing the reliable fixed of LED area and from sending out
Favourable Heat transmission of the optical diode region to housing.
Fixture is preferably able to be made up of Merlon (Polykarbonat).The material is characterised by with regard to by luminous two
Favourable characteristic in terms of the penetrability of the light that pole pipe region produces.
Additionally, the material meets the requirement in terms of elasticity, the elasticity is for compressing LED area
It is needs on housing.
Housing is preferably able to by extrudate, and the extrudate being for example made up of aluminum is formed, to be encased in rail vehicle.
The extrudate can for example be a part for the luggage carrier or deck component of rail vehicle.
Need to be emphasized that, the fixture being made up of elastomeric material not necessarily entirely must light along the longitudinal direction of housing
Stretch on diode area.Although luminous two are obtained in the case of completely overlapped between spring chuck and LED area
Thermal coupling as well as possible between pole pipe region and housing.As long as but permission LED area is run, then also can
LED area is fixed using multiple fixtures enough, and the fixture is therefore, it is possible to arranging selectively along housing.
Description of the drawings
Below with reference to the accompanying drawings embodiment of the present utility model is explained in more detail.Unique accompanying drawing is illustrated for rail vehicle
Light-emitting device viewgraph of cross-section.
Specific embodiment
As drawn from accompanying drawing, light-emitting device 1 is equipped with housing 2, application feelings of the housing in rail vehicle
Can be formed by the extrudate being made up of aluminum under condition, the extrudate is for example associated with the luggage carrier of rail vehicle.Just
For this, housing 2 extends several meters along the longitudinal direction of rail vehicle if necessary.
It is U-shaped that the inner chamber of housing 2 is closed on three sides adjacent to each other and is configured to.The holding of housing 2 is opened wide
Side 3 for rail vehicle application in towards the rail vehicle inner chamber.Opposite with open side 3 in housing 2
LED area 4 is provided with side, and there is the LED area circuit board 5, wherein circuit board 5 to abut in shell
The discharge of heat can be realized on body 2 when LED area 4 is run.
LED area 4 is not directly anchored on housing 2.More precisely, LED area 4 only by means of
The plastic clamp 6 being for example made up of Merlon presses to following housing sides, and LED area 4 is abutted on the housing side.
The plastic clamp 6 for being configured to elongated plastic strip provides such elasticity so that the plastic clamp is by light-emitting diodes area under control
Domain 4 presses to housing side associated there.For this purpose, plastic clamp 6 stretches and at two in the inside of housing 2 arc
It is supported in longitudinal direction side in guide protrusions 7, the guide protrusions are from the open side 3 of housing 2 towards 4 structure of LED area
Into ladder, the longitudinal direction side of fixture 6 is abutted on the ladder.
When LED area 4 is installed, the LED area is inserted in housing 2 first in the above described manner.
Followed by, fixture 6 is inserted in housing 2, more precisely, being inserted into housing under conditions of being supported in guide protrusions 7
In.Here, fixture 6 is abutted in LED area 4 with intermediate portion section 8, and the longitudinal direction side of the fixture is fixed
Position after 7 rear of guide protrusions elastic deformation be so that LED area 4 is pressed to associated there by the fixture
Housing side.Arcuate shape is produced accordingly, for for fixture 6 on the horizontal direction of housing 2, the arcuate shape is in fixture 6
Intermediate section 8 region in be pressed into.
