Two bearing holes are corresponding up and down and are coaxially disposed, and top and the lens of the UV LED packaging body installation cavity lift
Chamber perforation is provided with light hole, and the light hole is arranged with circular hole coaxial perforation.It, can be easily and effectively with this structure design
UV LED packaging body is installed in UV LED packaging body installation cavity, later by being set to
The light modulating device of mirror lifting intracavitary carries out secondary light modulation to it, and the utility model is simple in structure, facilitates processing, at low cost.
Description of the drawings
Fig. 1 is a kind of front view of fixed frame for UV LED device of the utility model.
Fig. 2 is the sectional view of Section A-A in Fig. 1.
Specific implementation mode
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
In conjunction with shown in Fig. 1 to Fig. 2, a kind of fixed frame for UV LED device is present embodiments provided, is wrapped
Include cylindrical body, the circular hole 11 for being set to the cylindrical body upper surface, be set to the cylindrical body upper surface and
Circumferentially be distributed in multiple first axle bearing bore 12 of 11 surrounding of the circular hole, be set to inside the cylindrical body and with the circle
The lens lifting chamber 13 of the perforation setting of hole 11, the UV LED packaging body peace for being set to the cylindrical body bottom surface
It behave affectedly and 14 and is set to the cylindrical body lower face and circumferential is distributed in the UV LED packaging body installation
Multiple second bearing holes 15 of 14 surrounding of chamber；The first axle bearing bore 12 and about the 15 second bearing hole correspond to and coaxially set
