Abstract
A distribution photometer automatic tracking detecting device is mainly used for the photometric performance tests of various room lamps, street light fittings and light projecting lamps and the total light flux test of light source. The conventional technology has the deficits of low measuring accuracy and big measuring error. The utility model includes a stand which is characterized in that the stand is provided with a rotation mechanism which can rotate along a horizontal shaft. The rotation mechanism is connected with an anti-dazzling tubular by an angle modulator. The rear part of the anti-dazzling tubular is provided with an optical receiver. By setting synchronous rotation, the tested light is directly injected into the optical receiver which better eliminates stray light, reduces errors and improves measuring accuracy.
Description
[technical field]
The utility model relates to a kind of automatic system of lamp distribution performance test, is mainly used in the test of the test of light distribution performance and the light source total light flux of all kinds of indoor lamps, roads light and floodlight.
[background technology]
Existing distribution photometer as shown in Figure 1, during test measured light is fixed on the test bench 2, make measured light do rotation around vertical axis, simultaneously, optical mirror 3 is that rotate around horizontal axis at the center with the measured light, and receive the light of mirror reflects, thereby record the luminous intensity distribution performance of measured light with sniffer.
General equal can not the rotation of present distribution photometer sniffer, its optical receiver 8 is horizontally disposed with.For eliminating parasitic light, in the darkroom (or camera bellows) of distribution photometer test, one bucket-shaped extinction chamber 11 and diaphragm 12 is set in the optical receiver front side, because the rotation of optical mirror 3, require the diaphragm aperture efficiency bigger, more like this parasitic light also can reflex on the sensitive surface of detector by wall, ground, distribution photometer main body etc., thereby influences measuring accuracy; Tested in addition beam optical axis brings measuring error because of the oblique optical receiver that is mapped to; Bucket-shaped extinction chamber needs a stationary installation, and part has stopped flashlight.
[utility model content]
In order to overcome the above-mentioned defective that exists in the prior art, the utility model provides a kind of distribution photometer automatic tracing detecting apparatus, to reach the minimizing measuring error, guarantees the purpose of measuring accuracy.
The utility model is by the following technical solutions: the automatic tracing detecting apparatus of a kind of distribution photometer, comprise support, it is characterized in that described support is provided with the rotating mechanism that can rotate along transverse axis, this rotating mechanism connects a cone by an angle adjusting mechanism, and the rear side of described cone is provided with optical receiver.Angle adjusting mechanism is in order to regulate cone and optical receiver and horizontal angle, make it consistent with the angle of tested beam optical axis, rotating mechanism drive cone and optical receiver rotate with the angular velocity same with optical mirror (synchronously) during measurement, thereby guaranteed in measuring process, tested light does not shine directly on the optical receiver with not stopped, tested beam optical axis and optical receiver axis coincide, and have reduced measuring error effectively, have improved measuring accuracy.
As further improving and replenishing to technique scheme, the utility model adopts following technical measures: the sensitive surface of described optical receiver is centered close to the rotation axis intersection of cone central shaft and rotating mechanism, the optical receiver central shaft overlaps with the cone central shaft, the sensitive surface center that has guaranteed optical receiver always is in center of rotation in rotation, thereby accurately receives tested light.
Be provided with some diaphragm for eliminating stray light in the optical receiver front side in the described cone, the central authorities of diaphragm for eliminating stray light have light hole, and light hole is greater than incident ray optics light pipe cross section.Light hole only need be slightly larger than incident ray optics light pipe cross section, guarantees effectively to eliminate parasitic light, guarantees measuring accuracy.
The quantity of described diaphragm for eliminating stray light is at least three, guarantees the eliminate stray light effect.
The beneficial effects of the utility model are: by synchronous rotation is set, make tested light direct beam to optical receiver, eliminated parasitic light preferably, reduced error, improved measuring accuracy.
[description of drawings]
Fig. 1 is that existing distribution photometer is measured view.
Fig. 2 is a structural representation of the present utility model.
Fig. 3 measures view for the utility model.
[embodiment]
The automatic tracing detecting apparatus of distribution photometer as shown in Figure 2, support 4 is provided with rotating mechanism 5, rotational structure 5 connects cone 7 by angle adjusting mechanism 6, the rear side of cone 7 is equipped with optical receiver 8, the sensitive surface of optical receiver 8 is centered close to the rotation axis intersection of cone 7 center lines and rotating mechanism 5, and optical receiver 8 central shafts overlap with cone 7 central shafts.Be provided with at least three diaphragm for eliminating stray light 9 in the cone 7, diaphragm for eliminating stray light 9 central authorities have light hole, and light hole is greater than incident ray optics light pipe cross section.
During measurement, sniffer is installed on the fixed station 10, the center of rotation of rotating mechanism 5 and optical mirror 3 is overlapped, regulate the angle of cone 7 and optical receiver 8, make it consistent with the angle of tested beam optical axis.Then, measured light 1 is done rotation around vertical axis, and optical mirror 3 is that rotate at the center with measured light 1, and rotating mechanism 5 rotates synchronously with optical mirror 3, records the photometric distribution of this distance.
Then, change the distance between sniffer and the distribution photometer, repeat above-mentioned steps, just can accurately record the luminous intensity distribution performance of measured light thus.
