Description
Technical Field
The utility model relates to a hand-held type laser positioning illuminometer, especially, be used for the perpendicular illuminance test in stadiums.
Background
Illuminance is an essential parameter for evaluating the quality of various ambient lighting, and can be divided into horizontal illuminance and vertical illuminance. The horizontal illumination test is simpler, and the illuminometer probe is placed on a horizontal plane to be tested to read data. The vertical illuminance test involves a certain directivity which is relatively complex, wherein the most difficult place is a stadium with rebroadcast conditions. When the vertical illumination in the direction of the main camera is tested, the light receiving axial direction of the illuminometer detector is ensured to be aligned to the main camera at each test position of a stadium, and the test angle is required to be adjusted at each test position because only one main camera is fixed in position. At present, the adjustment of the light receiving direction of the illuminometer is finished by visual observation, certain time and energy are needed to be consumed for accurately positioning the direction by visual observation, and the error and the repeatability of the test are not ideal.
Disclosure of Invention
Not enough to prior art, the utility model provides an illuminance meter that the degree of accuracy is high, good reproducibility, convenient to use.
The utility model discloses a realize through following technical scheme: the utility model discloses an illuminometer, illuminometer photic device and laser instrument constitute, wherein: the laser is fixed above the handheld illuminometer light receiver through screws, and light emitted by the laser is parallel to the optical axis of the illuminometer light receiver on the same vertical plane.
The laser is a red laser powered by a button battery, a fixing screw is arranged at the bottom of the laser, the height of the laser is 3cm, and the diameter of the laser is 1.5 cm.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic diagram of the laser of the present invention.
Fig. 3 is a schematic diagram of the application of the present invention.
Wherein, 1 illuminometer, 2 illuminometer light receiver, 3 illuminometer light receiver center, 4 laser, 5 set screw, 6 main camera position, 7 illuminometer test position.
Detailed Description
The structure is shown in figure 1, the utility model comprises an illuminometer 1, an illuminometer light receptor 2 and a laser 4. The laser 4 is arranged right above the illuminometer light receiver 2 of the illuminometer 1 through the fixing screw 5, and light rays emitted by the laser 4 and the optical axis of the center 3 of the illuminometer light receiver are ensured to be on the same vertical plane. And the fixing screw 5 is adjusted to make the light emitted by the laser 4 parallel to the optical axis of the light receiver center 3 of the illuminometer. In order to prevent the laser 4 from shielding the illuminometer light receiver 2, the height of the laser 4 is 3cm, the diameter is 1.5cm, and the distance between the edge of the laser 4 and the edge of the illuminometer light receiver 2 is 1 cm.
In use, at each illuminometer test location 7 in the stadium, the laser 4 is aimed at the primary imaging location 6 by adjusting the orientation of the illuminometer 1 as shown in fig. 3. And simultaneously, the reading of the illuminometer 1 is locked, and the data is the vertical illumination of a certain test point in the direction of the main camera. The utility model discloses can be fast convenient location direction, improve measuring accuracy and repeatability, do not additionally increase complicated device, labour saving and time saving. Especially for large stadiums with many test points, the working efficiency is improved, and the test cost is reduced. The utility model discloses a fine market perspective has.
