Description
Technical field
The invention belongs to light source technology, more particularly to a kind of uniform source of light generator.
Background technology
Uneven light source, which is radiated on object, can cause the uneven reflection of object, that is to say, that object meeting in reflection
There is bright region and dark region, the region of light and shade be exactly uneven light source can cause it is uneven caused by, thus
Illuminated object, which can be shown as, has bright region and than dark region.Briefly occurred by the object of light source irradiation dark
Region be just the absence of reflected light, it is exactly too strong because of reflected light bright region occur by the object of light source irradiation.It is non-homogeneous
Light source can make the light of the part of subregion within sweep of the eye more than other parts, so as to cause the reflection of object uneven.
On the contrary, uniform light source is radiated on object, object just occurs that the reflection of same brightness, rather than non-homogeneous light source go out like that
Existing two kinds of regions of light and shade.In daily life, most of our used light sources are light sources heterogeneous.Such as during we are daily
The illuminating lamp used, because the light source of illuminating lamp is not that the light that uniform light source causes illuminating lamp to send can not uniformly shine
Penetrate, light source be radiated on object can not substantially uniformity light reflection object, so object can be caused to go out under conditions of illumination
Existing part is especially bright, and some parts can be than dark.Uniform source of light is needed to can be only achieved in the imaging system in laboratory
The demand of experiment, it is impossible to meet the condition of experiment in general light source；The uniform source of light generator of prior art is due to its structure
Complexity causes cost higher, causes generally to use in the imaging experiment of laboratory；Also being unfavorable for the popularization of uniform source of light makes
With.
The content of the invention：
The technical problem to be solved in the present invention：A kind of uniform source of light generator is provided, to solve the production of the uniform source of light of prior art
Raw device causes cost higher because its is complicated, causes generally to use in the imaging experiment of laboratory；Also it is unfavorable for
Even light source such as promotes the use of at the technical problem.
Technical solution of the present invention：
A kind of uniform source of light generator, it includes integrating sphere and non-homogeneous light source installation spheroid, and integrating sphere inwall side is fixed with
Non-homogeneous light source installs spheroid；Integrating sphere bottom offers uniform source of light light-emitting window；It is provided with the top of non-homogeneous light source installation spheroid
Non-homogeneous light source light-emitting window, non-homogeneous light source installation sphere inner wall are uniformly fixed with non-homogeneous light source.
Integrating sphere inwall and non-homogeneous light source installation spheroid outer wall scribble reflecting material；The reflecting material is uniformly applied to
On integrating sphere inwall and non-homogeneous light source installation spheroid outer wall；The reflecting material is magnesia or barium sulfate.
Non-homogeneous light source installation spheroid is fixedly mounted on integrating sphere left side, right side or the bottom for being arranged on left and right sides simultaneously.
The radius of non-homogeneous light source installation spheroid is the 25-30% of the integration radius of a ball.
The opening diameter of non-homogeneous light source light-emitting window is the 20%-25% that non-homogeneous light source installs sphere diameter.
Uniform source of light light extraction port radius are the 20%-25% of the integration radius of a ball.
Non-homogeneous light source is light emitting diode；Non-homogeneous light source quantity is more than two.
Integrating sphere inwall is fixed with non-homogeneous light source installation spheroid by double faced adhesive tape；Non-homogeneous light source is pacified with non-homogeneous light source
Dress sphere inner wall is fixed by double faced adhesive tape.
Beneficial effects of the present invention：
The present invention leaves non-homogeneous light source in the spheroid of outlet installed in one, this hair（It is bright）Non-homogeneous light source selection luminous two
Pole pipe, because light emitting diode has the advantages of photochromic pure and appearance and size is flexible, appearance and size is flexibly and easily in spheroid
Installation, the photochromic pure generation for contributing to final uniform source of light of light emitting diode.
The spheroid for being fixed with non-homogeneous light source is referred to as non-homogeneous light source installation spheroid by the present invention.Non-homogeneous light source installs ball
The radius of body is about to integrate 1/5th of the radius of a ball to arrive a quarter；Integrating sphere is that inwall is hollow with high reflection material
Spheroid.The opening of non-homogeneous light source light-emitting window be not easy it is too big, the diameter of outlet be about uniform source of light installation spheroid three/
One, outlet too conference causes last light source not uniform enough, exports the too small effect that can influence last light source.
Non-homogeneous light source installation spheroid is fixed on integrating sphere inwall left and right sides by the present invention, and the position placed is integrating sphere
Left and right sides the latter half, the light source that uniform source of light light-emitting window is launched is exactly the uniform source of light needed；In the inwall of integrating sphere
Reflecting material is coated, reflecting material there must be good reflecting effect, and reflecting material will uniformly be coated in integrating sphere
Inwall, reflecting material integrating sphere inner surface must be a complete geometry sphere, and the radius of integrating sphere has to equal everywhere；
The non-homogeneous light source light-emitting window that the light of the non-homogeneous light source of installation installs spheroid by non-homogeneous light source is irradiated in integrating sphere
Wall, then reflex to the outlet of integrating sphere in the inwall of integrating sphere, the light that integrating sphere outlet is sent is exactly uniform source of light；This
Inventive structure is simple, and cost is cheap；Solve the uniform source of light generator of prior art cause because its is complicated cost compared with
Height, cause generally to use in the imaging experiment of laboratory；Also it is unfavorable for the technical problem such as promote the use of of uniform source of light.
Brief description of the drawings：
Fig. 1 is schematic structural view of the invention.
