Abstract
The present invention relates to a rotary working table of a distribution photometer, which comprises a base and a horizontal rotation main shaft fixed on the base, wherein one end of the main shaft is tightly fixed with one end of a big arm and a cantilever. The big arm is perpendicular to the main shaft, and the center line of the cantilever is coincident with a shaft line of the main shaft, and the other end of the cantilever is fixed with a reflective mirror which forms an angle of 45 DEG with the main shaft. The other end of the big arm is fixed with a synchronous rotating shaft which is parallel to the main shaft and synchronously rotates with the main shaft in the reverse direction. One end of the synchronous rotating shaft is fixed with one end of a lamp arm, and the other end of the lamp arm is provided with a vertical rotating shaft which is used for connecting a lamp fitting. The rotary working table of the present invention is always in a vertical position with the lamp arm when the reflector is rotated. Thus, when the lamp fitting with high strength gas at the inside is measured, the stabilization of light emission of the lamp is ensured to be constant when the lamp fitting is inverted. The measurement lamp fitting arranged on the vertical shaft rotates around the vertical shaft, and light sent from each direction of the lamp fitting is reflected to a luminosity probe through the reflective mirror of 45 DEG. Thus, the photometric parameter of space distribution of the lamp fitting can be accurately measured.
