The utility model can prevent the disturbance of environmental light and increase the lighting evenness of every optical disc.
Description
Technical field
The utility model relates to a kind of illumination proving installation, and particularly a kind of test light disc is to the illumination proving installation of the permanance of illumination.
Background technology
In recent years, using discs to store data is the data storage mode of more and more popularizing, and comparatively speaking, the turnout of discs is also increasing, and thus, the quality of discs is a mass-produced important indicator; Discs must be passed through multinomial severe environmental testing, just can produce colory discs.The environmental testing wide range of discs, for example resistance to impact, repetitive read-write etc., and one of them important environmental testing is the illumination test, its test light disc is to permanance (light durability) test of illumination.
In the illumination test of prior art, only utilize simple illumination testing apparatus to carry out the illumination test of discs usually; Please refer to shown in Figure 1ly, the illumination testing apparatus 1 of prior art comprises a bracing frame 11, several light sources 12 and a supporting part 13, and wherein light source 12 is arranged on the bracing frame 11, and relative with supporting part 13 and establish.
From the above, when the illumination testing apparatus 1 of utilizing prior art was carried out the illumination test of discs 2, discs 2 was arranged on the supporting part 13, and comes irradiates light disc 2 with the light that light source 12 sends.Yet, because bracing frame 11 is an open space, therefore when carrying out the illumination test, can be subjected to the interference of light source 12 surround lighting in addition, for example, light of placing the light in the test room of illumination testing apparatus 1, coming in from test room external exposure or sunlight etc. all can influence the accuracy of illumination test data.
In addition, owing to light source 12 and supporting part 13 relative establishing, that is be that the light that light source 12 is sent only shines supporting part 13 from the top, therefore can cause the angle difference of several discs 2 reception illumination on the supporting part 13, the result makes that the degree of each discs 2 illumination is inhomogeneous, further can influence the result of illumination test.
Therefore, how to provide a kind of illumination proving installation that can avoid the interference of surround lighting and increase the uniformity coefficient of each discs irradiation, real in needing most one of improved problem at present.
Summary of the invention
Because above-mentioned problem, the purpose of this utility model is to provide a kind of illumination proving installation that can solve ambient light interference.
Another purpose of the present utility model is to provide a kind of illumination proving installation that is subjected to the light uniformity coefficient that can improve discs.
Thus, for reaching above-mentioned purpose, illumination proving installation of the present utility model comprises a housing and several light sources.In the utility model, housing is made up of the shell face of several regular polygons; Light source is arranged in the confined space that is made of the shell face, and is arranged at respectively on each shell face with several discs to be tested, to be used for carrying out the illumination test of discs.
From the above,, can stop surround lighting, and then promote the accuracy of the data of illumination test because of having a confined space according to illumination testing apparatus of the present utility model; In addition,, and light source is set,, thereby can makes discs be subjected to even and equal illumination so each discs illumination degree is identical in each shell face because of foundation illumination testing apparatus of the present utility model is just many bodies.

Embodiment
Hereinafter with reference to relevant drawings, the illumination proving installation according to the utility model preferred embodiment is described, wherein identical assembly will be illustrated with identical reference marks.
Please refer to shown in Figure 2ly, comprise several square shell face 31 and several light sources 32 according to the illumination proving installation 3 of the utility model preferred embodiment.In the present embodiment, six square shell faces 31 are formed confined spaces 33, and six light sources 32 are arranged at respectively on six square shell faces 31 in the confined space 33.The person of noting, the illumination proving installation 3 shown in the present embodiment is a regular cube, in addition, illumination proving installation 3 can also be the regular polygon of other type, for example is the positive tetrahedron (not shown); In addition, if illumination proving installation 3 is positive N face body, and N levels off to infinity, and then illumination proving installation 3 is a spherosome.
The square shell face 31 of present embodiment can be a reflecting surface, makes discs 2 not only receive the light of light source 32, absorbs the light that is reflected by shell face 31 more in addition, to shorten the time of discs 2 tests.In addition, square shell face 31 can also be the extinction face, and it can absorb the light that light source 32 is sent, and reflects in confined space 33 to avoid light, therefore can make test more stable.
The light source 32 of present embodiment can be a pointolite, and it can dwindle the volume of illumination proving installation 3, or increases the number of discs 2 to be tested.In addition, light source 32 can be daylight lamp, but the daily surround lighting of emulation is to the influence of discs 2; Light source 32 also can be high-octane ultraviolet light, so that accelerate the test duration of discs 2.
For content of the present utility model is more readily understood, stretch-out view according to the illumination testing apparatus 3 of the utility model preferred embodiment is described hereinafter with reference to Fig. 3.
As shown in Figure 3, illumination testing apparatus 3 is made up of six square shell faces 31, and each light source 32 is arranged on each shell face 31 symmetrically, that is be respectively at device light source 32 on shell face 31 central points, it is the pointolite of iso brightness, identical size in the present embodiment, and discs 2 be positioned over respectively with light source 32 distance equate, and on the diagonal line of square shell face 31 position of (as shown in the figure).Because illumination testing apparatus 3 is a regular cube, so each discs 2 is all identical with the opposite position and the angle of each light source 32, please refer to Fig. 2, so each discs 2 received total irradiate light amount from each light source 32 is identical.
In sum,, surround lighting can be blocked in outside the shell face, and then can improve the accuracy of the data of illumination test because of being a confined space according to illumination testing apparatus of the present utility model; In addition,, and will wait the light source of brightness to be arranged on the central point of each shell face because of foundation illumination testing apparatus of the present utility model is a regular polygon, thus can make discs be subjected to even and equal illumination, so that improve the accuracy of illumination test.
The above only is an illustrative, but not is restricted person.Anyly do not break away from spirit of the present utility model and category, and, all should be contained in the described claim its equivalent modifications of carrying out or change.
