Abstract

The utility model relates to a color photometer with an automatic SCE (specular excluded)/SCI (specular included) switching function, which comprises an illuminating source, an integrating sphere, a first sensor and a second sensor. A measuring port corresponding to a tested article is arranged at the bottom of the integrating sphere, an incident port is disposed on the top of the integrating sphere, a light path is arranged between the illuminating source and the tested article via the incident port, the first sensor is arranged on a regular reflection path of light rays of the illuminating source, the regular reflection path is formed after the light rays pass through the incident port of the integrating sphere along the light path and irradiate on the tested article, and the second sensor is disposed on the same integrating sphere. Compared with a common color photometer, the color photometer has the advantages that complexity of an internal system of a product is reduced due to the simple structure, the usage frequency of devices is reduced, accordingly, cost of the product is lowered, non-mechanical operation is simpler, usage is facilitated, and risks of faults are reduced.

Description

The colour photometer that automatic SCE/SCI switches

[technical field]

The utility model relates to a kind of color measurement instrument, the colour photometer that particularly a kind of automatic SCE/SCI with two inductors switches.

[background technology]

Colour photometer has been widely used in the color management field of industries such as plastic cement, printing, paint, printing ink, textile garment at present; In to testee test color; Because there is the direct reflection situation in the part testee; Normally adopt through the mechanical means that combines with light and select to eliminate or do not eliminate the data that direct reflection reaches test SCE and SCI; But this method can cause device complicated and use complex steps, and is unfavorable for reducing the structure miniization of the cost and the product of product, has improved the risk of fault again.

A kind of in addition method is to have realized the automatic switchover of SCE/SCI through double beam system; But this method has structurally been Duoed a light path than common colour photometer; Increase the complicacy of instrument internal structure, be unfavorable for the microminiaturization of product structure, 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 to increase the colour photometer that an inductor has promptly been realized the SCE/SCI automatic switching function.

The purpose of the utility model is achieved in that and comprises lighting source, integrating sphere, light path, first inductor and second inductor; Said integrating sphere bottom is provided with the measuring port of corresponding testee; The top is provided with an entrance port; Between lighting source and testee, the light that said first inductor is arranged at lighting source is radiated on the normal reflection path behind the testee along the entrance port of light path through integrating sphere said light path through the entrance port; Said second inductor is arranged on the same integrating sphere;

Preferably, described lighting source is a LED luminous lighting light source;

Preferably, said integrating sphere is provided with two exit portals, respectively corresponding two inductors.

Compared with prior art; The beneficial effect of the utility model is: the utility model is compared common colour photometer, has only increased an inductor, and two inductors are surveyed the data of SCE and SCI respectively; Realized the SCE/SCI function, have simple in structure with help the advantage of the miniaturization of products; Simple designs simplification the complicacy of product built-in system, reduced the use of device, thereby reduced the cost of product; The operation of on-mechanical formula is simpler, and is easy to use, reduced the risk of fault; Adopt LED luminous lighting light source, compare the tungsten lamp or the xenon lamp that adopt in the conventional art, not only reduced cost, and simple in structure, help the product structure microminiaturization.

Reference numeral: integrating sphere 1, measuring port 11, entrance port 12, first exit portal 13, second exit portal 14, testee 2, first inductor 3, second inductor 4, light path 5, the path 51 of normal reflection light, lighting source 6

[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 that a kind of automatic SCE/SCI of the utility model switches; It comprises lighting source 6, integrating sphere 1, light path 5, first inductor 3 and second inductor 4; Said integrating sphere 1 bottom is provided with a measuring port 11, and testee is positioned over measuring port 11 places of integrating sphere 1, and the top of integrating sphere 1 is provided with an entrance port 12; Said light path 5 is between lighting source 6 and testee 2; When the light of lighting source 6 is injected integrating sphere 1 and is radiated at testee 2 surface by the entrance port 12 of integrating sphere 1; The surface of testee 2 produces a normal reflection light, and this normal reflection light produces the path of a normal reflection light; Said first inductor 3 and second inductor 4 are located at integrating sphere 1 place, and wherein, said first inductor 3 is provided with the top of integrating sphere 1, are positioned on the path 51 of normal reflection light, and said integrating sphere has first exit portal 13 on the path 51 of corresponding normal reflection light; Said second inductor 4 is arranged at the side of integrating sphere 1, and said integrating sphere 1 offers second exit portal 14 on the position of corresponding second inductor 4.

Wherein, the lighting source 6 in above-mentioned adopts LED luminous lighting light sources, compares the tungsten lamp and the xenon lamp that adopt in the conventional art, has not only reduced cost, and simple in structure, makes product structure microminiaturized.

Adopt said structure; When the illuminating bundle that lighting source sends, inject integrating sphere through light path, when being radiated at the testee surface; Produce and diffuse and normal reflection light; First inductor can detect diffusing and normal reflection light of testee, second inductor can detect testee through diffusing behind the integrating sphere integration, calculate through the light data that first inductor and second inductor are detected; Can obtain the data of SCE/SCI respectively, realize the function of SCE/SCI.

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.
