Specifically, the human body sensing device is electrically connected with the projection device 1 and can control the projection lens of the projection device 1 to be opened or closed, further, after the human body sensing device senses a human body, the human body sensing device controls the projection lens of the projection device 1 to be closed, and if the human body sensing device does not sense the human body, the human body sensing device controls the projection lens of the projection device 1 to be opened.
Further, the projection device 1 is in a projection screen 4 installation mode, and the human body sensing device is controlled to be turned off, so that the projection device 1 or the projection screen 4 is prevented from being affected.
Optionally, the human body sensing device may be an infrared human body sensing device or a motion human body sensing device, as long as a human body can be sensed in a set area, and the specific form is not set.
In this optional embodiment, a human body sensing device is arranged on the projection device 1, and when an installer performs operations such as punching on the projection area of the projection device 1 on the wall surface 3, the human body sensing device controls the projection lens of the projection device 1 to be closed after sensing a human body, so that the influence of projection light rays of the projection device 1 on the installer can be avoided.
Fig. 4 is a projection screen installation interface in a projection screen installation mode of a projection apparatus according to an exemplary embodiment.
In this alternative embodiment, the arrangement shape of the 4 wall hanging screw holes 52 of the projection screen mounting interface 5 is a rectangle, the center point 51 of the projection screen mounting interface 5 is located at the center of the rectangle, and the stability of the projection screen 4 is better.
Further, the projection screen mounting interface 5 is rectangular, the arrangement shape of the 4 wall-hanging screw holes 52 of the projection screen mounting interface 5 is rectangular, and the distance from the center point 51 to the position of the wall-hanging screw hole 52 and the distance from the center point 51 to the vertex of the projection screen mounting interface 5 satisfy the following relationship:
L2＝0.9*L1*cosα
wherein, L2 is the distance from the center point 51 of the projection screen mounting interface 5 to the position of the wall-hanging screw hole 52, L1 is the distance from the center point 51 of the projection screen mounting interface 5 to the vertex, and α is the included angle between the straight line from the center point 51 of the projection screen mounting interface 5 to the wall-hanging screw hole 52 and the horizontal side line of the projection screen mounting interface 5.
The smaller the angle α between the straight line from the center point 51 of the projection screen mounting interface 5 to the wall-hanging screw hole 52 and the horizontal side line of the projection screen mounting interface 5, the larger the distance L2 from the center point 51 of the projection screen mounting interface 5 to the position of the wall-hanging screw hole 52 is relative to the distance L1 from the center point 51 of the projection screen mounting interface 5 to the apex, and the more stable the mounting of the projection screen 4 is.
It is to be understood that the present invention is not limited to the procedures and structures described above and shown in the drawings, and that various modifications and changes may be made without departing from the scope thereof. The scope of the invention is limited only by the appended claims.
