In the installation process of the beam bunching device, in order to finely adjust the position of the beam bunching device, as shown in fig. 1, a plurality of waist-shaped installation holes 6 can be arranged on the base 1, and the base 1 is fixed in front of the pipe sleeve output window of the bulb tube assembly by fastening screws penetrating through the waist-shaped installation holes 6. When the light ware position is restrainted in needs adjustment (i.e. when adjusting the field size), only need unscrew fastening screw, make base 1 and regulating body 2 remove to the position of expectation, screw up the screw afterwards, realize fixed can.
For example, the base 1 may have a rectangular plate shape, and one kidney-shaped mounting hole 6 may be respectively provided at four corners of the base 1.
The adjusting body 2 is disposed on the base 1 for adjusting the size of the radiation window 101, and the structure of the adjusting body 2 capable of realizing this function is exemplified as follows:
as an example, as shown in fig. 2, the base 1 has a guide channel 102 adapted to the adjusting body 2, the guide channel 102 has a radiation window 101 therein, and the size of the radiation window 101 is adjusted by moving the adjusting body 2 along the guide channel 102 to change the shielding area of the radiation window 101.
Wherein the guide channel 102 and the adjustment body 2 are adapted to each other such that the adjustment body 2 is only displaced along the guide channel 102 without unnecessary displacements in the guide channel 102. For example, when the guide channel 102 is a rectangular channel, the adjusting body 2 may be a rectangular block body adapted to the rectangular channel.
The guide channel 102 may be of regular geometry or of irregular shape, provided that the adjustment body 2 adapted thereto is able to change the size and shape of the radiation window 101 when moving therein.
In the embodiment of the present invention, the guiding channel 102 may not only allow the adjusting body 2 to move therein, but also allow the adjusting body 2 to be taken out from it from multiple directions, for example, along the moving direction thereof, or along the direction perpendicular to the surface of the base 1, and the structure of the guiding channel 102 meeting such requirements includes but is not limited to: rectangular channels, trapezoidal channels, etc.

For the structure of the guide channel 102 with a stop section, the following are exemplified: first, the guide passage 102 may include at least two sections having different widths, wherein a section located at the lowermost portion has the largest width and serves as a stop section. For example, the guide channel 102 may be a channel of a convex shape (i.e. two-step) (see fig. 5), and correspondingly the adjustment body 2 may be a convex block.
Secondly, the guiding channel 102 may be a single segment, but its width gradually decreases from bottom to top, wherein the lower segment may be a stop segment. For example, the guide channel 102 may be a dovetail channel (see fig. 6), a semi-circular arc channel, or the like.
It should be noted that, with the base 1 as a reference, the upper surface is in an upper orientation, and the lower surface is in a lower orientation, and the terms "upper and lower" in the above-mentioned orientation may be used as a standard.
A protrusion may be provided on the upper surface of the base 1, and the guide passage 102 may be opened on the protrusion. The bottom of the guide channel 102 may be flush with the upper surface of the base 1, so that the radiation window 101 opened on the base 1 may be located at the bottom of the guide channel 102.
