The invention further relates to the combination lamps especially as a part application in a motor vehicle of operating element.Its example
It is arranged as such, i.e., the second light emitting region comprising the transmission structure defines boundary or the circumferential direction profile of contact surface.
Detailed description of the invention
The present invention is described in detail by the following drawings.This attached drawing is exemplary at this, only represent one it is excellent
The embodiment of choosing.Wherein:
Fig. 1 shows the embodiment of combination lamp 1 according to the present invention in the cross-section.
Specific embodiment
Fig. 1 shows the embodiment of combination lamp 1 according to the present invention.The combination lamp 1 has light-emitting component 3,
It is limited by multiple light sources along line setting with the make of SMD, the form of these light sources is light emitting diode.The hair
Optical element 3, which has, emits related emission characteristics with its light, is indicated by light intensity distributions 5, and lead in Fig. 1
The rodlike distribution crossed in cross-sectional view is schematically shown.Here, schematically showing the angle of the luminous intensity of the light-emitting component 3
Spend dependence.In the case, the light intensity distributions 5 are symmetrical and define main transmitting by its maximum luminous intensity
Direction H.
The light-emitting component 3 is arranged to that it is made to carry out backlight illumination to the diffuser layers 2 of plane.Here, towards the hair
The light receiving surface of one of two interareas of the surface 7 of optical element 3 as the diffuser layers 2 composition diffuser layers 2, and institute
The surface 8 backwards to the light-emitting component 3 for stating diffuser layers 2 is relevant light gasing surface, is used in the diffuser layers 2
Or the light L3 diffused by the diffuser layers.
The reflector 4 of ellipse is provided between the diffuser layers 2 and the light-emitting component 3, form is groove
The mirror surface of shape forms the boundary of the free space between diffuser layers 2 and light-emitting component 3 from cross side.The luminous member
The light L1 of first space regional area 5a of the light intensity distributions 5 of part 3 is for directly carrying on the back the diffuser layers 2
Light irradiation, the reflector 4 of the ellipse is so set, make the second space regional area 5b of the light intensity distributions 5 (such as

On focal line f2.
Meanwhile the transmission structure 6 is in this way, i.e. it is direct by the light of the main direction of the launch H of the light-emitting component 3
(i.e. on reflector 4 areflexia) backlight illumination.
The diffuser layers 2 are also in this way, i.e. it has a first light emitting region 2a and the second regional area 2b, and described the
One light emitting region 2a is only shone by the first partial region 5a backlight illumination of the light intensity distributions 5, described second
Region 2b is by the second regional area 5b and first partial region 5a backlight illumination, but herein mainly by the light-emitting component
The second regional area 5b backlight illumination of the light intensity distributions 5.It is provided in the second light emitting region 2b
The transmission structure 6.First light emitting region (2a) of the diffuser layers 2 is greater than second hair for planar dimension
Light region 2b, and have wedge-shaped cross section, wherein its thickness D with the spacing of light-emitting component 3 and reflector 4 increase
And increase.
Therefore, the first light emitting region 2a is used to realize space illumination, brightness with light-emitting component 3 and reflector spacing
Increase and reduce.And it is used to realize with the second light emitting region 2b of the transmission structure 6 and relatively high brightness and determines
To illumination, the higher reason of brightness is: realizing direct backlight by the light of the main direction of the launch H of first partial region 5a
Irradiation, and additional backlight illumination is realized by light that is received via reflector 4 and focusing.Therefore by relatively small number of
Part provides a kind of combination lamp, both provides space illumination or provides directional lighting.
