The utility model comprises a main shaft, a main arm which is driven by the main shaft, a suspension shaft which is fixedly connected on the main arm and a reflecting mirror which is installed on the suspension shaft. An accessory shaft breadthwise crosses one end of the main arm and is connected with a lamp arm, and the suspension end of the lamp arm is provided with a vertical rotation shaft which is used to connect the light fixture. The test turntable of a distribution photometer is characterized in that a balance weight which is driven by the accessory shaft and matched with the lamp arm is provided. The test turntable of a distribution photometer has the advantages of easy installation, space saving, cost and processing saving and easy operation.
Description
[technical field]
The utility model relates to a kind of distributed photometer test table, is used to measure the space distribution curve and the corresponding photometric parameter of light fixture light.
[background technology]
Ray space distribution curve and corresponding photometric parameter are the important performance indexes of light fixture, also are the basic datas of illuminating engineering design, and the measurement of this index is normally realized with distributed photometer.
Existing distributed photometer test table as shown in Figure 1, comprise main shaft 1, by the principal arm 2 of main shaft drives, be fixed in the outstanding axle 3 on the principal arm and be installed in reflective mirror 4 on the outstanding axle, principal arm 2 is vertical with main shaft 1, one end of principal arm 2 is provided with an asessory shaft 5 and links to each other with arm 6 by ring flange 10, the end that suspends of arm 6 is equipped with vertical rotation axis 7, is used for connecting light fixture.During work, be fixed on tested light fixture 8 on the vertical rotation axis 7 and light, driving miscellaneous part by main shaft 1 again rotates around its axle center, meanwhile, asessory shaft 5 is along the direction rotation opposite with main shaft 1, make vertical rotation axis 7 remain vertical position, guarantee that the test light fixture is in normal ignition position in measuring process, the light that light fixture sends reflexes on the outer intelligent luminosity probe of turntable by placing the reflective mirror 4 on the outstanding axle 3, thereby realizes the measurement to the space distribution curve and the corresponding photometric parameter of light fixture light.Various light fixtures are because the needs that use, and beam projecting direction different (have upwards also have downward) also needs to rotate separately the lighting position that arm 6 changes light fixture and reaches the measurement purpose during measurement.Wherein, arm 6 is a cantilever beam structure, torque to asessory shaft 5 is very big, realize that arm 6 rotates (when rotating especially from bottom to up) and will overcome this torque, existing method has two kinds: the one, and only depend on the output torque of asessory shaft 5 self to overcome the torque that arm 6 produces, just need the speed reduction unit of powerful motor and big retarding ratio to come to provide bigger moment of torsion, like this cost height to asessory shaft 5, and being limited to the space structure of turntable, big motor, speed reduction unit are difficult to install; The 2nd, drag arm 6 by manpower, very inconvenient.
[utility model content]
In order to overcome the above-mentioned defective that exists in the prior art, the utility model provides a kind of distributed photometer test table, with the torque of balance arm generation preferably, reaches the purpose that is easy to install, save the space, saves cost, avoids manually-operated inconvenience.
The technical scheme that the utility model adopted is: a kind of distributed photometer test table, comprise main shaft, by the principal arm of main shaft drives, be fixed in the outstanding axle on the principal arm and be installed in reflective mirror on the outstanding axle, asessory shaft is horizontally through an end of principal arm and links to each other with arm, the end that suspends of arm is provided with a vertical rotation axis that is used to connect light fixture, it is characterized in that: other establishes a counterweight that is driven and matched with described arm by asessory shaft.The torque that counterweight can the balance arm be produced, thus as long as select low power motor for use, the speed reduction unit of little reduction gear ratio also can be realized rotating freely of arm fully, has saved cost, has saved the space, does not also need manpower.
Counterweight of the present utility model and arm are integral structure.Integral structure helps the fixing of counterweight and arm relative position.
Be connected with a ring flange between asessory shaft of the present utility model and the arm, counterweight is fixed on the ring flange and the corresponding opposite side of arm.Ring flange is used for connecting asessory shaft and arm, and counterweight and arm are installed in ring flange discretely, is convenient to adjust and change.
Counterweight of the present utility model is made of with the balancing weight that is connected the installing plate other end the installing plate that an end is connected on the ring flange.Can make counterweight processing more convenient like this, be convenient to produce.
The center of gravity of counterweight of the present utility model and arm is positioned on the plane that comprises the asessory shaft center line, and the both sides of asessory shaft axis again that distribute.Being provided with like this is beneficial to the counterweight torque of balance arm generation better.
The beneficial effects of the utility model are: be easy to install, save the space, save cost, processing, easy to operate.

[embodiment]
As shown in Figure 2, main shaft 1 is affixed with principal arm 2, outstanding axle 3 and reflective mirror 4, and principal arm 2 is vertical with main shaft 1.
One end of principal arm 2 is provided with an asessory shaft 5, and asessory shaft 5 links to each other with the axle head of arm 6 by a ring flange 10, and the relative position of asessory shaft 5, ring flange 10, arm 6 is also all fixed, and asessory shaft 5 is parallel with main shaft 1, and drives arm 6 and main shaft 1 backwards rotation.
Another of arm 6 suspends to hold and is connected with vertical rotation axis 7, but vertical rotation axis 7 in the vertical directions rotate with respect to arm 6.
During work, be fixed on tested light fixture 8 on the vertical rotation axis 7 and light, driving miscellaneous part by main shaft 1 again rotates around its axle center, meanwhile, asessory shaft 5 is along the direction rotation opposite with main shaft 1, make arm 6 remain the upright position, the light that light fixture sends reflexes on the outer intelligent luminosity probe of turntable by placing the reflective mirror 4 on the outstanding axle 3, thereby realizes the measurement to the space distribution curve and the corresponding photometric parameter of light fixture light.As want the beam projecting direction of conversion light fixture, and only need cooperate the speed reduction unit of little reduction gear ratio moment of torsion to be provided for asessory shaft 5 with low power motor, change the position of tested lamp again by the arm 6 and the rotation of vertical rotation axis 7.
Above-mentioned is a preferable implementation method, can make appropriate change according to instructions according to actual conditions.
