As an improvement to the technical solution of the present invention, the louvers rotate 360° around the rotation axis.

Working principle of the present invention:

When the light sensor collects the light intensity, it is transmitted to the single-chip microcomputer through signal conditioning and signal AD conversion. The single-chip microcomputer controls and drives the stepping motor to work, and drives the louvers to rotate at a certain angle. When the light intensity is weak, the louvers rotate at 0° -20° or so, let the light fully enter the room; when the light is strong, the rotation angle of the louvers is about 70°-80°, and some light can come in; when the light is normal, the rotation angle is about 40°-70°. The rotation angle of the louver is 0°, which is the horizontal position, and the outer end is reversed to a positive angle. When the manual mode button is pressed, the louver rotates from 0° to 360° until it is adjusted to the indoor light desired by the operator and stops.

The present invention compares with prior art, and its beneficial effect is:

1. The light-sensing automatic control light-transmitting curtain device of the present invention regulates the angle of the blinds through the data collected by the light sensor to control the indoor light.

2. The light-sensing automatic control light-transmitting curtain device of the present invention can meet people's requirements for indoor lighting through manual adjustment.

3. The light-sensitive automatic control light-transmitting curtain device of the present invention has a simple structure and is easy to use, and can be widely used in home curtains to automatically or manually adjust indoor light.

detailed description

The technical solutions of the present invention will be described in detail below, but the protection scope of the present invention is not limited to the embodiments.

In order to make the content of the present invention more obvious and comprehensible, further description will be made below in conjunction with accompanying drawings 1-2 and specific implementation methods.

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

Example:

As shown in Figure 1, it is the light-sensing automatic control light-transmitting curtain device of the present embodiment;

The light-sensitive automatic control light-transmitting curtain device of this embodiment includes a curtain part, a light-sensitive part and a curtain control part, the light-sensitive part is arranged on the curtain part, and the curtain control part is connected to the curtain part to drive the curtain part to open or close automatically.
