The speed of height encapsulation.Simultaneously as metallic heat radiating plate 11, insulating radiation plate 12 and outer heat sink 5 are directly pressed by mounting cup 4
Tightly, seamless contact is realized between three, it is to avoid metallic heat radiating plate 11 and insulating radiation plate 12 weld the hole for causing so that
The performance of radiating is greatly improved, and without heat-conducting glue is used, reduces cost, and convenient maintenance, change parts and
The recycling of each parts.In addition, first being converged to laser using convex lens 10,3 pairs of remittances of concavees lens are then recycled
Laser after poly- carries out shaping, and the injection for making laser parallel, intensive not only increases the transmission power of laser, while improve
The controllability of laser.
In order to further improve performance of the present utility model, as shown in figure 5, the metallic heat radiating plate 11 and insulating radiation plate
12 relative plate faces are respectively provided with the first ladder platform 13 and the second ladder platform 14, the size and second-order of first ladder platform 13
The matching size of halfpace 14 is closed, that is, the first ladder platform 13 and the second ladder platform 14 are in metallic heat radiating plate 11 and insulating radiation plate
Also fitted completely during 12 laminating, left no gaps therebetween.First ladder platform 13 is equal towards the one side of the second ladder platform 14
Even setting plurality of rods body 15, the body of rod 15 extends along the length direction of metallic heat radiating plate 11.It is right in second ladder platform 14
Multiple rod aperture 16 being engaged with the body of rod 15 should be set, in the insertion rod aperture 16 of the body of rod 15.The body of rod 8 is rounded or square
Shape, rod aperture 16 is engaged with the body of rod 15, when the body of rod 15 is rounded, the radiating between metallic heat radiating plate 11 and insulating radiation plate 12
Area is bigger, and when the body of rod 15 is square, the connection between metallic heat radiating plate 11 and insulating radiation plate 12 is spacing more stable.
During assembling, after VCSEL chip arrays 6 are welded, metallic heat radiating plate 11 and insulating radiation plate 12 are first spliced, Ran Houzai
Interior heat sink is integrally put into mounting cup 4.So, due to the presence of the first cascaded surface 13 and the second cascaded surface 14, make
The heat exchange area for obtaining metallic heat radiating plate 11 and insulating radiation plate 12 is bigger, is easy to the heat fast transfer on metallic heat radiating plate 11.
On the one hand the setting of the body of rod 15 and rod aperture 16 further increases heat exchange area, on the other hand also causes metallic heat radiating plate 11 and absolutely
Connection between edge heat sink 12 is more stablized.
For the ease of the installation of concavees lens 3, more preferable way is that the exit wound of bullet 2 is in be made up of outer section, stage casing and inner segment
The ladder for diminishing successively from outside to inside it is poroid, the concavees lens 3 include mirror body and picture frame, the picture frame be located at exit wound of bullet 2 in
On the cascaded surface of section.Pressing plate 17, the position relative with mirror body on the pressing plate 17 are set on the cascaded surface of the outer section of the exit wound of bullet 2
Through hole is set, and the edge of the pressing plate 17 is affixed with body 1 by bolt.The picture frame is compressed by pressing plate 17.It is recessed installing
It is first to prevent on the cascaded surface in the stage casing of exit wound of bullet 2 picture frame of concavees lens 3 during lens 3, then pressing plate 17 is installed, using pressure
Plate 17 compresses the fixation that picture frame realizes concavees lens 3.
Further, with reference to Fig. 1,3 and 5, it is shown mounting cup 4 is carried out on outer heat sink 5 in order to preferably it is spacing, while
In order to improve the speed of encapsulation, more preferable way can also be the outer heat sink 5 towards setting in the plate face of mounting cup 4 and peace
The groove that the connecting portion 8 of dress cover 4 is engaged, the connecting portion 8 is located in groove.So, install mounting cup 4 when
Wait, it is possible to directly connect portion 8 and be put into groove, re-tighten bolt.So not only increase package speed and determine
The accuracy of position, while can also tighten to adapt to the interior heat sink of different-thickness by bolt, versatility is stronger.In addition, this reality
With new convex lens 10 install can using concavees lens 3 mounting means, that is, light-emitting window be also provided with it is stepped, will be convex
The picture frame of lens 10 is arranged on the cascaded surface in light-emitting window and is compressed by another pressing plate 17 again.In order to avoid VCSEL chips
Light that array 6 sends is escaped, and the distance between convex lens 10 and VCSEL chip arrays 6 should not be excessive, that is to say, that now convex lens
Mirror 10 is often not suitable for setting picture frame, but only mirror body, therefore, more preferable way is, with reference to shown in Fig. 1,2 and 4, the peace
Dress cover 4 sets the conical surface 18 being engaged with the surface of convex lens 10 towards the surface of exit wound of bullet 2, and the edge of the convex lens 10 leads to
Cross fluid sealant be bonded with the conical surface 18.
