The window blind is divided into a first subsection located above and a second subsection located below, wherein the dimming blade 12 included in the first subsection is defined as a first dimming blade and the dimming blade 12 included in the second subsection is defined as a second dimming blade.
The plurality of optical fibers are distributed in the second glass substrate of the first dimming blade, and the optical fibers are provided with a first end part and a second end part along the extending direction.
The first end of the optical fiber in each first dimming blade extends to the upper edge and is connected with the second end of the optical fiber in the first dimming blade in the previous layer, the second end of the optical fiber in each first dimming blade extends to the lower edge and is connected with the first end of the optical fiber in the first dimming blade in the next layer, and one end of the optical fiber in the first dimming blade at the top extends to the third first groove and is connected with one L ED lamp bead.
Through the installation mode, optical fibers in the first dimming blades are connected to form a longer optical fiber serving as a linear light source, and light emitted by L ED lamp beads is effectively guided into the dimming blades 12.
Preferably, the optical fiber is flat, so that the thickness of the dimming blade 12 is reduced, and a better lighting effect is achieved.
In some examples, a plurality of lamp bead holding cavities are separately arranged in the first groove, and one or more L ED lamp beads are arranged in each lamp bead holding cavity, so that the installation is facilitated, and the safety of L ED lamp beads is effectively protected.
For example, the lamp pearl holds the chamber structure the same, and equidistant distribution, L ED lamp pearl evenly distributed holds the intracavity at the lamp pearl to even whole illumination area's illuminating effect.
Second mounting means
The optical fiber is distributed and arranged in the second glass substrate of the first dimming blade, and one end of the optical fiber is connected with one L ED lamp bead.
L ED lamp beads are not installed on the top but installed on the side wall, and only the optical fiber needs to be horizontally arranged in the first dimming blade, so that the light emitted from L ED lamp beads can be guided into the dimming blades 12.
In the first kind of mounting means, because L ED lamp pearl sets up at the top, therefore the first blade of adjusting luminance that distributes and have optic fibre sets up at the top, in the second kind of mounting means, because L ED lamp pearl sets up on the lateral wall, therefore does not have the restriction to the distribution position of first blade of adjusting luminance, and the user can arrange the installation by oneself as required.
Although the present invention has been described with reference to the preferred embodiments, it is not intended to limit the present invention. The present invention is intended to cover by those skilled in the art various modifications and adaptations of the invention without departing from the spirit and scope of the invention. Therefore, the protection scope of the present invention is subject to the claims.
