Abstract

The utility model provides an optical system for having more a colored LED lamp pearl formation of image lamp includes LED light source, even light microscopic head, the logical unthreaded hole of formation of image and imaging lens according to the light path direction in proper order, the LED light source includes the LED base plate and locates many colored LED lamp pearls on the LED base plate, three the same plane -convex spherical mirrors of even light microscopic pretext are constituteed, the aperture of the logical unthreaded hole of formation of image is unanimous with the light -emitting window bore of even light microscopic head, imaging lens is including focusing mirror and play light microscopic. The utility model discloses in even light microscopic head press close to the LED luminous face, the light 80% or more that makes the LED light source send gets into even light microscopic head, becomes even facula at the light -emitting shape of face of even light microscopic head, controls within 35 through the angle of divergence of even light microscopic head light, the formation of image is led to the unthreaded hole and is close to even light microscopic head play plain noodles, is used for the formation of image, imaging lens will lead to the unthreaded hole and form images at a distance, and the formation of image is clear, and the facula is even, finely tune the position of imaging lens focusing mirror, can become the picture that leads to the unthreaded hole to arbitrary apart from the position.

Description

A kind of optical system for many color LED lamp bead imaging lamps

Technical field

This practicality is related to field of LED illumination, especially a kind of optical system for many color LED lamp bead imaging lamps.

Background technology

For existing LED imaging lamp, typically first with condenser, each lamp bead is carried out with imaging, light source after optically focused, then colour mixture Arrangement is limited by condenser, and light-emitting area is larger, and structure is more complicated, and light fixture volume is larger, and hot spot uniformity is not high.

Content of the invention

Technical problem to be solved in the utility model is to provide a kind of optics for many color LED lamp bead imaging lamps System, structure is simple, and colour mixture is uniform, imaging clearly.

For solving above-mentioned technical problem, the technical solution of the utility model is：One kind is for many color LED lamp bead imagings The optical system of lamp, includes LED/light source, even smooth camera lens, imaging light hole and imaging lens successively according to optical path direction；Described LED/light source includes LED-baseplate and many color LED lamp bead in LED-baseplate, and described even smooth camera lens is put down by three identicals Convex spherical mirror forms, and the aperture of described imaging light hole is consistent with the light-emitting window bore of even smooth camera lens, and described imaging lens include Focusing lens and go out light microscopic.In the utility model, LED/light source light-emitting area pressed close to by even smooth camera lens, make that LED/light source sends more than 80% Light enters even smooth camera lens, forms uniform light spots in the exiting surface of even smooth camera lens, controls through the angle of divergence of even smooth camera light Within 35 °；It is imaged light hole near even smooth camera lens exiting surface, for being imaged；Light hole is imaged onto at a distance by imaging lens, imaging Clearly, hot spot uniformly, is tailored into the position as lens focusing mirror, can become the picture of light hole to any distance and position.

As improvement, described color LED lamp bead is large-power LED light bead, and LED lamp bead close-packed arrays reduce light loss.

As improvement, the light inlet of described even smooth camera lens is corresponding with described LED/light source, receives light source 80% and is entered with glazed thread Enter, improve source efficiency, exiting surface hot spot is uniform.

As improvement, the light that LED/light source sends is within the even light microscopic head angle of divergence is reduced to 35 °.

As improvement, the focussing distance of described imaging lens is 70mm-80mm.

The beneficial effect that the utility model is compared with prior art brought is：

It is light source using many densely arranged high-power colorful LED lamp bead, be made up of three identical planoconvex spotlights even Light camera lens, LED/light source light-emitting area pressed close to by even smooth camera lens, and the light of make that LED/light source sends more than 80% enters even smooth camera lens, even The exiting surface of light camera lens forms uniform light spots, and light hole size is consistent with even smooth camera lens light-emitting window warp, and near even smooth camera lens Exiting surface, uniformly, for being imaged, imaging lens by focusing microscope group and go out light microscope group and form hot spot, and focal length 70mm-80mm, to logical Light borescopic imaging, imaging clearly hot spot uniformly, is adjusted to the position as lens focusing microscope group, light hole can be imaged onto any position Put.

Brief description

Fig. 1 is the utility model index path.

Specific embodiment

With reference to Figure of description, the utility model is described in further detail.

As shown in figure 1, a kind of optical system for many color LED lamp bead imaging lamps, wrap successively according to optical path direction Include LED/light source 1, even smooth camera lens 2, imaging light hole 3 and imaging lens 4.

Described LED/light source 1 includes LED-baseplate and is arranged on densely arranged many high-power colorful LED in LED-baseplate Pearl.

Described even smooth camera lens 2 is made up of three identical planoconvex spotlights 7, and the light inlet of all light camera lenses 2 presses close to LED/light source 1, Make LED/light source 80% enter even smooth camera lens 2 with glazed thread, improve source efficiency；Permissible through the divergence of beam angle of even smooth camera lens 2 Control within 35 °, and exiting surface hot spot be uniformly,

The aperture of described imaging light hole 3 is consistent with the exiting surface of even smooth camera lens 2, and the exiting surface near even smooth camera lens 2.

Described imaging lens 4 by focusing microscope group 5 and go out light microscope group 6 and form, and focal length is 70mm-80mm, to imaging light hole 3 Imaging, imaging clearly, adjustment focusing microscope group 5 position, can by imaging light hole 3 be imaged onto optional position.

In the utility model optical system, LED/light source 1 light-emitting area pressed close to by even smooth camera lens 2, make that LED/light source sends 80% with On light enter even smooth camera lens 2, form uniform light spots in the exiting surface of even smooth camera lens 2, light hole 3 size gone out with even smooth camera lens 2 Optical port warp is consistent, and the exiting surface near even smooth camera lens 2, and uniformly, for being imaged, imaging lens 4 by focusing microscope group 5 and go out hot spot Light microscope group 6 forms, focal length 70mm-80mm, light hole 3 is imaged, imaging clearly, and hot spot uniformly, adjusts imaging lens 4 focusing lens Light hole can be imaged onto optional position by the position of group 5.
