Embodiment 1
[0040] refer to figure 1 , a method for measuring and adjusting a planar light-emitting device, wherein the large-scale planar light-emitting device 101 is formed by splicing nine planar light-emitting modules, and is divided into a module A area, a module B area, and a module C area. The measurement and adjustment of the planar light-emitting module 107 in the module A area of the planar light-emitting device 101 is used as an example below. The measurement and adjustment principles of other planar light-emitting modules are basically similar to those of the planar light-emitting module 107 .
[0041] First, at the installation site of the planar light emitting device 101, the data of the planar light emitting module 107 is actually measured, and the measurement data is recorded. The data is: the height of the observation point 102 is h, the height from the center point of the planar light emitting module 107 in module A area to the ground is H, and the horizontal distance ...
Embodiment 2
[0055] A system for measuring and adjusting planar light-emitting devices, wherein the planar light-emitting devices are composed of several planar light-emitting modules, the system includes measuring equipment, and the system also includes an inclination adjustment device, which is connected with the planar light-emitting modules that need to be measured , for obliquely setting the planar light-emitting module, and obtaining the brightness characteristic value of the planar light-emitting module under the observation angle a by the measuring device, thereby generating adjustment data corresponding to the planar light-emitting module;
[0056] Wherein, the included angle between the line connecting the center point of the planar light emitting module and the measuring device and the normal line of the center point of the planar light emitting module is the observation angle a.
[0057] As mentioned above, by actually measuring the data of each planar light-emitting module at t...
Embodiment 3
[0061] see Figure 5 In this embodiment, on the basis of Embodiment 2, the inclination adjustment device further includes a communication module, a storage module and an adjustment module. Wherein the communication module is used to input the observation angle of view a and transmit it to the storage module; the storage module is used to save the observation angle of view a; the adjustment module is used to read the observation angle of view a in the storage module, And set the plane light-emitting module obliquely. The rest of the principles are the same as those of the second embodiment, and will not be repeated here.
[0062] In this embodiment, the inclination adjusting device can conveniently and directly adjust the planar light-emitting module by directly inputting the viewing angle a, which speeds up the processing.
