Abstract
The utility model relates to a kind of brightness calibration devices, in particular for the brightness devices of photo-biological safety test system.The utility model includes that annular cover plate, reflective mirror, cross groove and fixed screw are constituted, wherein: the annular cover plate, there is fixed screw for surrounding, the ring-shaped iron plate of middle opening, the reflective mirror is the circular flat mirror of back side metal-plated membrane, the cross groove, it is the groove that the width marked at the center at the reflective mirror back side is 0.5mm for two orthogonal grooves of light transmission on reflective mirror center.The intersection point of light transmission cross groove is overlapped with the center at the center of reflective mirror and annular cover plate.The utility model can quickly and easily solve the problems, such as the calibration positioning and focusing of luminance standard lamp, while the cover sheet as luminance standard lamp, not increase complex appts additionally, time saving and energy saving, improve work efficiency, reduce testing cost.The utility model has good market application prospect.
Description
Technical field
The utility model relates to a kind of brightness calibration devices, fill in particular for the brightness of photo-biological safety test system
It sets.
Background technique
Currently, the photo-biological safety for testing various illuminating products is all completed by spectrometer.Spectrometer passes through test illumination
The irradiance spectrum and spoke luminance spectral of product, calculate whether magnitude limit value that meet national standards.In order to obtain accurately
Numerical value requires to carry out illumination and brightness calibration every time before test.Illumination calibration is fairly simple, and only illumination need to be popped one's head in and be inserted into
Lighting standard lamp.In comparison, brightness calibration wants troublesome more, and luminance standard lamp is usually the integral of a side opening
Ball.When calibration, at a distance of 20cm, the optical center of luminance meter will be with the opening of integrating sphere for the camera lens of luminance meter and the opening of integrating sphere
Center be overlapped, while adjusting the camera lens of luminance meter, make opening face imaging clearly.It can be seen that reach accurate positioning and at
As clearly needing to expend certain time and energy.
Summary of the invention
In view of the shortcomings of the prior art, the utility model provides a kind of simple, easy to use, the high-efficient brightness school of structure
Standard apparatus.
Originally practical to be newly achieved through the following technical solutions: the utility model includes annular cover plate, reflective mirror, cross
Groove and fixed screw are constituted, in which: the annular cover plate has fixed screw, the ring-shaped iron plate of middle opening for surrounding.
The reflective mirror is the circular flat mirror of back side metal-plated membrane.
The cross groove is two orthogonal grooves of light transmission on reflective mirror center, is the center at the reflective mirror back side
The width marked is the groove of 0.5mm.The intersection point of light transmission cross groove and the center of reflective mirror and the center of annular cover plate weight
It closes.
Detailed description of the invention
Fig. 1 is the use schematic diagram of the utility model.
Fig. 2 is the covering plate structure schematic diagram of the utility model.
Wherein, 1 brightness is popped one's head in, 2 focusing lens, 3 light, 4 reflective mirrors, 5 luminance standard lamps, 6 annular cover plates, 7 fixed spiral shells
Silk, 8 cross grooves.
Specific embodiment
Structure is as shown in Fig. 2, the utility model includes annular cover plate 6,7 structure of reflective mirror 4, cross groove 8 and fixed screw
At, in which: the annular cover plate 6 has fixed screw 7, the ring-shaped iron plate of middle opening for surrounding.
The reflective mirror 4 is the circular flat mirror of back side metal-plated membrane.
The cross groove 8 is two orthogonal grooves of light transmission on 4 center of reflective mirror, is in 4 back side of reflective mirror
The width that the heart marks is the groove of 0.5mm.In the intersection point of light transmission cross groove 8 and the center of reflective mirror 4 and annular cover plate 6
The heart is overlapped.
In use, as shown in Figure 1, whole device carries out in optical dark room.The light source in luminance standard lamp 5 is opened, thoroughly
The cross groove 8 crossed on reflective mirror 4 forms a cross light 3.The position for adjusting luminance standard lamp 5, makes in cross light 3
The heart is radiated at the center of brightness probe 1.The focal length for adjusting focusing lens 2 again makes 8 imaging clearly of cross groove.Pass through fixed spiral shell
Silk 7 removes annular cover plate 6, can enter the calibration test stage.It avoids passing through repeatedly machinery positioning and finds luminance standard lamp and bright
The center of degree probe is overlapped.It also avoids being inconvenient to the phenomenon that focusing because of no marks object in luminance standard lamp light-emitting surface simultaneously.
The utility model can quickly and easily solve the problems, such as the calibration positioning and focusing of luminance standard lamp, while as luminance standard lamp
Cover sheet, do not increase complex appts additionally, it is time saving and energy saving, improve work efficiency, reduce testing cost.This is practical new
Type has good market application prospect.
