Three parts can be divided into: first part is the paraxial light being directly incident upon on convex lens 66, and second part is to project farther out off axis
Light onto LED reflector 65, Part III are the light being projected directly on lens retroreflective bowl 67, this three parts light passes through direct projection
With reflection is final all projects by convex lens 66, when 63 light-emitting surface of LED light module to the distance of convex lens 66 is close to zero,
The light that LED light module 63 issues, which is substantially all, has been emitted directly toward convex lens 66, and the light that directive convex lens 66 issues is dissipated in wide-angle

Plate multi-layered antireflection coating in 66 two sides；Each LED light module 63 is not to install in parallel, in this way shining in LED light module 63
When the distance of face to convex lens 66 is the focal length F of convex lens 66, the light beam that multiple adjustable angle of divergence spotlights project away passes through
It is overlapped mutually, the light luminance in illuminated area will be made uniform, LED light module 63 can be sent out by eliminating single lighting module 6
The pattern projection of smooth surface internal structure goes out that area to be illuminated domain is caused to illuminate irregular disadvantage；In order to obtain required colour rendering index
And colour temperature, each LED light module 63 might not select the model of same spectral characteristic, it can be using a variety of different spectrum
LED light module 63 be combined；Convex lens 66 is fixed on lens mount 4, the inner groove surface of 5 junction of lens mount 4 and pedestal
Between be fixed with the accordion sealing curtain 17 that a circle is suppressed in advance, by LED light module 63, LED reflector 65, lens retroreflective bowl
67 and the inside of convex lens 66 space and the space of 3 inner sidewall surrounding of lamp box formed it is ventilative it is dust-proof be isolated, in addition, in lens mount
It is equipped with dustband 16 between 4 and the combination side wall of pedestal 5, prevents dust and the grains of sand from entering in lamp box 13.

In I, the short focus convex lens is fixed in the mounting hole of seat surface in lens mount 4 and short focus convex lens and LED light position pair
It answers, and by being passed through the cooling of cold wind or cold water realization to LED light into the waterway channel 10 inside 5 seat surface of pedestal.
If the diameter of 63 light-emitting surface of LED light module is d, the focal length of convex lens 66 is F, is according to minimum light beam angle
The relationship of arctan (d/F), if minimum light beam angle is certain, then the size of LED light module 63 is bigger, the focal length of convex lens 66
Also bigger, the axial dimension of lamp box 3 is also bigger, there may come a time when the limitation because to 3 axial dimension of lamp box, it is desirable that by lamp box 3
Flattening, that is, the axial dimension of lamp box 3 is compressed as far as possible.As long as d and F is reduced simultaneously and keeps ratio constant,
The axial length of lamp box 3 can be compressed；Specifically, we can change larger-size great power LED light emitting module 63
For the lesser LED light of size and small-bore short focus convex lens, and cancel heat conduction supporting column 61 and lens retroreflective bowl 67, directly will
LED light and LED reflector I are fixed in a thermally conductive good pedestal 5 on seat surface, and impose air-cooled or water cooling to pedestal 5, such as
It is that this does the result is that can still obtain the lesser angle of divergence in long drive in the lesser situation of 3 axial dimension of lamp box.
In the technical program, as shown in Figure 1, lamp box 3 is mounted on adjustable rotary pivoted frame 2, the adjusting of orientation angle is by side
After position motorised vertical axis rotating seat 201 rotates, make bracket 202 with 201 synchronous rotary of vertical axis rotating seat to realize；Pitching
The adjusting of angle drives the lamp box horizontal direction being mounted on bracket 202 rotation to realize by pitching motor 203；With 3 light of lamp box
The camera 9 and rangefinder 11 that axis is installed in parallel can be continuously shot the image of target at work and measure target and lamp box 3
Distance, manipulator pass through video image manipulate searchlight orientation angle and pitch angle after realize to irradiation target chase after
Light；Manipulator can manually adjust, and can also be automatically adjusted by computer and be aimed at and tracked, specific method is: adjustment side
Target's center is shifted to the cross hair of video image by parallactic angle and pitch angle, the searchlight obtained by rangefinder 11 and target
The angle of divergence of the projecting beam of distance adjustment searchlight.
