Description

Adopt the colour photometer of illumination location

[technical field]

The utility model relates to a kind of color measurement instrument, particularly a kind of colour photometer that adopts the illumination location.

[background technology]

Known colour photometer is a kind of simulation eye-observation color, and provides the instrument of result's objective measurement color, is widely used in the color management field of industries such as plastic cement, printing, paint, printing ink, textile garment.Existing colour photometer has two kinds of methods when sample is positioned, a kind of is through on instrument, offering mechanical observation window, and another kind is through in instrument, having additional the electronic monitoring element; These two kinds of localization methods not only need be offered the through hole of corresponding mechanical light side window mouth or electronic monitoring element on integrating sphere; It has reduced the data accuracy that obtains when measuring; Also need on instrument, offer observation window or increase the electronic monitoring element; Increase the complicacy of product structure, be unfavorable for the microminiaturization of product, improved the cost of product.

[summary of the invention]

The purpose of the utility model is to overcome deficiency of the prior art, provides a kind of and need not on instrument, to offer mechanical observation port or set up a kind of colour photometer that adopts illumination location that the electronic monitoring element can position measured target.

The purpose of the utility model is achieved in that it includes integrating sphere, illuminating source, light path system, governor circuit and chromatic measuring system, and said integrating sphere upper end is provided with the entrance port, and the lower end is provided with measuring port; Said light path system has light inlet and light-emitting window, and the light-emitting window of said light path system is communicated with the entrance port of integrating sphere, and the light inlet place of light path system is provided with illuminating source; It is characterized in that: saidly inject the center of the light of the illuminating source in the integrating sphere through said measuring port by light path system; Said illuminating source and test macro are electrically connected at governor circuit, include also that the control illuminating source starts separately or control knob that control illuminating source, chromatic measuring system start simultaneously, and said control knob is electrically connected at governor circuit;

Preferably, described illuminating source is the LED illuminating source.

Compared with prior art; The beneficial effect of the utility model: the colour photometer of the employing illumination location of first the utility model is when realizing positioning function; Need not to add any hardware device, help simplifying the structure of product, realize the microminiaturization of product; Reduce the cost of product, improve reliability of products; It two is mechanical observation window or through holes of electronic monitoring element of offering on the integrating sphere that need not in the utility model in the corresponding old technology, has increased the accuracy of data when measuring; It three is to adopt led light source, and not only lighting effect is good for it, and power consumption is little, and the life-span is long, has reduced cost, and simple in structure, helps the product structure microminiaturization; It four is to realize rapidly measured target is positioned, and is simple, convenient, flexible.

[embodiment]

Below in conjunction with accompanying drawing and embodiment the utility model is done and to be further described:

With reference to shown in Figure 1, the colour photometer of the employing illumination of the utility model location, it comprises housing 1 and is arranged at integrating sphere 2, illuminating source 3, light path system 4, governor circuit 5 and the chromatic measuring system in the housing; Said integrating sphere 2 upper ends are provided with an entrance port 21, and the lower end is provided with a measuring port 22; Said light path system 4 has a light inlet 41 and a light-emitting window 42, and the light-emitting window 42 of said light path system is connected with the entrance port 21 of integrating sphere, and light inlet 41 places of light path system are provided with illuminating source 3, and described illuminating source 3 is a led light source; The incident ray 31 of said illuminating source 3 can be injected in the integrating sphere 2 by light path system, penetrates integrating sphere 2 through the center of measuring port 22; Said housing 1 is provided with a control knob 6, and said control knob 6, illuminating source 3 and chromatic measuring system are electrically connected at governor circuit 5.

The colour photometer of the employing illumination location of the utility model is when positioning; Pressing control knob 6 does not unclamp; Governor circuit 5 control illuminating sources 3 are luminous; The incident ray 31 that illuminating source 3 sends enters into light path system 4 by the light inlet 41 of light path system, injects in the integrating sphere 2 through the entrance port 21 of the integrating sphere that is connected with the light-emitting window 42 of light path system again, and measuring port 22 places that are radiated at integrating sphere 2 lower ends form a hot spot; Measuring port near measured target 7, through visual, can be judged rapidly that measured target 7 is whether in hot spot, to realize the purpose of location; After the positioned, unclamp and discharge control knob 6, the chromatic measuring system in the governor circuit 5 control colour photometers starts, and measured target 7 is carried out colour examining, and after colour examining finished, illuminating source 3 extinguished.

Wherein, the illuminating source 3 in above-mentioned adopts led light sources, compares the tungsten lamp and the xenon lamp that adopt in the conventional art, and not only lighting effect is good for it, and power consumption is little, and the life-span is long, has reduced cost, and simple in structure, makes the product structure microminiaturization.

In sum, the utility model only need be pressed control knob and not put in use; Illuminating source starts separately, and the light that sends through light source positions measured target, after the positioned; Unclamp and discharge control knob; Illuminating source and chromatic measuring system start simultaneously, and colour photometer carries out colour examining, and instrument cut out after colour examining finished; Compare colour photometer in the old technology when realizing positioning function; Need offer mechanical observation window on the instrument or on instrument, set up the electronic monitoring element; The colour photometer of the employing illumination location of the utility model need not to add any hardware device, helps cost, the raising reliability of products simplifying product structure, reduce product; Can realize fast and accurately measured target being positioned, simple during operation, convenient, flexible.

According to the announcement and the instruction of above-mentioned instructions, the utility model those skilled in the art can also carry out suitable change and modification to above-mentioned embodiment.Therefore, the embodiment that discloses and describe above the utility model is not limited to is in the protection domain of the claim that also should fall into the utility model to some modifications and the change of the utility model.In addition, although used some specific terms in this instructions, these terms are explanation for ease just, the utility model is not constituted any restriction.
