Being followed by the reflector 4 of optics 3, the reflecting surface 4a of this reflector is towards optics 3.
The light sent from optics 3 deflects laterally, preferably substantially enters top half space.
To this end, the surface 4a of reflector 4 can be spherical crown shape and be directed at optics 3.
Light emitting diode 2a, 2b and reflector 4 are fixed at keeper 5, and this keeper has flat
Row in longitudinal axis L extend pillar 5a, wherein these pillars on keeper top by means of the first base plate 7
And it is connected with each other by means of the second base plate 8 in keeper bottom.Light emitting diode 2a, 2b pass through
Circuit board 34 is fixed at the first base plate 7, and reflector 4 is then maintained by pillar 5a.Optic
Part 3 can such as be directly anchored at keeper 5, or can such as be fixed at circuit board 34.
Second base plate 8, outside it, i.e. deviates from reflector 4, it is provided that for one bearing-surface 9 of handle, just
As be illustrated in Figure 2.
Deviating from light emitting diode 2a at the first base plate 7, the side of 2b is flatly provided with cooling body 10,
So that the waste heat produced by light emitting diode 2a, 2b can pass through circuit board 34 and the first base plate 7
It is transferred in cooling body 10, and heat is sent to around by convection current by cooling body at least in part
In air.Cooling body 10 is unrestricted in terms of its type, can include such as volume cooling body,
There is the cooling body etc. of heat pipe (" Heat Pipe ").
A part of heat can also be continued transmission by cooling body 10, as be illustrated in Figure 2.
To this end, can make deviate from the lateral surface compressing of keeper 5 or be squeezed in another cooling body, the most preferably
Ground is by a kind of heat transfer material (TIM), and this heat transfer material is the most such as with TIM-pad 11
Form illustrate.Heat transfer material can be alternatively the thickest but also soft heat conducting film.Second
Base plate 8 is by other element 2a, 2b, 3, and 4,5a, 7,10 stretch out in side, and can be because of
This is used as stopper section.
Light emitting module 1 can be made a unit and can be combined with remaining luminous body, particularly
Can carry out integrated in removable mode.Light emitting module 1 is particularly easy to be pushed away because of its elongate in shape
Enter.
Fig. 2 illustrates the side-looking of the luminous body 12 being integrated with light emitting module 1 in replaceable mode wherein
Profile.Luminous body 12 herein is such as designed to medical examining lamp.
Luminous body 12 has external shell body wall or the main body 13 of bowl-type, is similarly the reflector of bowl-type
(" external reflector ") 14 is placed in wherein.The basic configuration of external reflector 14 can be such as
Parabola shaped or free shape, and can (but not essential) be designed to about light emitting module 1
Longitudinal axis L symmetrical.Alternatively, it is also possible to main body 13 and external reflector 14 to be designed as one,
Realize by such as the medial surface of main body ' 13 being done designed in mirror image.The reflecting surface of external reflector 15
Typically can be more much larger than the reflecting surface of the reflector 4 of light emitting module 1, the most ten times greater.
Lamellar cover plate 16 is fixed at the front free edge 15 of main body ' 13, outside its cover plate covers
Portion's reflector 14 and be basically perpendicular to the longitudinal axis L of light emitting module 1.Cover plate 16 has central void
17, insert or push light emitting module 1, namely by this space from outside (herein: bottom)
Say, until being used as the second base plate 8 of stopper section.Light emitting module, be disposed with cooling body 10 above
Top, light emitting module 1 or cooling body 10 are stretched out by the upper opening 18 of external reflector 14
And be pressed in main body 13 by soft TIM-pad 11.TIM-pad 11 especially can be with main body 13
Firmly connect, such as, glue in the above.
To the extruding of light emitting module 1 and fixing realized by handle 19, this handle is fixed on lid
On the outside 20 of plate 16, fix here by bolt 21.Along with handle being fixed on cover plate 16,
Handle 19 is pressed on the outside as bearing-surface 9 of the second base plate 8, and so that light emitting module 1
Compress main body 13.Except fixing light emitting module 1, therefore can also cooling body 10 and main body 13 it
Between realize good heat transfer.Therefore, main body 13 is used as another large-area cooling body, and this can
To improve the cooling to light emitting diode 2a, 2b.
In luminous body 12 running, light emitting diode 2a, 2b substantially completely pass through optic
Part 3 launches light, and therefore collimating reflector 4.By means of reflector 4, optical registration external reflector
14, light is again penetrated as angle pencil of ray by this external reflector by cover plate 16.Handle 19 basic bit
In the shadow of reflector 4, in order to the most slightly reduce light efficiency.Cover plate can be typically diffusion or
Transparent printing opacity.Reflector 4 and/or external reflector 14 can be typically diffusions or transparent reflective.
Can be by simply pulling out light emitting module 1 by it after unclamping (unloading bolt) handle 19
Remove and reload in turn.Therefore, enabling change light emitting module 1 the most easily.
In addition, it is not necessary that again light emitting module 1 is calibrated or similar operations.
Certainly, the present invention is not limited to the embodiment illustrated.
So, examinating light is generally not limited to medical, but can also be such as reading lamp.
