- the result of having investigated the difference in the illumination intensity of 4a with the digital illumination meter (made by Mother Tool Co., Ltd.) is shown.
- Fig. 6 shows a photograph of the entire office window seen from the outside.
- the window that shines in the center is the window to which the planar light emitter is attached. From this measurement result, the illuminance difference between the indoor side surface and the outdoor side surface in the window structure was about 8 times. At night, it was shining pale from the outside, and the inside could not be seen. In addition, when the outside was viewed from inside the veranda, it was partially reflected but could be seen through.
- the LED illuminator 23 is turned off, but it functions as a normal magic mirror and can be seen from the inside of the veranda. I could not see through.
- the window structure of the present embodiment during the daytime, it is possible to secure a view scenery from the indoor side (V1 side) and prevent peeping from the outdoor side (V2 side) by the magic mirror effect. Realized at night, peeping prevention from the outdoor side (V2 side) is realized by the light emitting effect.
- the window structure described so far can be applied to any attachment object having a hollow window structure (for example, a wall portion of a building, a signboard, or a shop show window). And by illuminating the outdoor side (V2 side), securing a view landscape from the indoor side (V1 side), preventing peeping from the outdoor side (V2 side), and further from the outdoor side (V2 side) It is possible to improve the design of the appearance of the visible attached object.
- a hollow window structure for example, a wall portion of a building, a signboard, or a shop show window.
- the window structure of the present embodiment can be applied to various windows because the light emitting device fits in the window frame.
- it can be applied to windows of trains and cars.
