The two redundant light-emitting lamp beads 221 of the first blade 211 and the two redundant light-emitting lamp beads 221 of the second blade 212 form a light-emitting center, the inner end part of the longest row of light-emitting lamps 220 of the first blade 211 is tightly connected with the inner end part of the shortest row of light-emitting lamps 220 of the second blade 212, the inner end part of the shortest row of light-emitting lamps 220 of the first blade 211 is tightly connected with the inner end part of the shortest row of light-emitting lamps 220 of the first blade 212, and then, as with the first embodiment, when the two rows of light-emitting lamps are tightly connected together, the light-emitting lamp beads 210 on the whole fan screen are distributed in a rectangular array, and (2N +2) x 2 light-emitting lamp beads are counted. In this way, compared with the first embodiment, the screen display at the light-emitting center position is clearer, and the visual effect is better.
In the third embodiment, as shown in fig. 3 to 6, the fan panel of the present embodiment is basically the same as that of the first embodiment, and the solution applied to the first embodiment and/or the second embodiment is also applied to the second embodiment. The main difference between the embodiment and the first embodiment lies in the number of the blades and the arrangement mode of the luminous lamp beads.
As shown in fig. 3, the fan panel according to the present embodiment includes a first blade 311, a second blade 312, a third blade 313, and a fourth blade 314 arranged in this order, wherein the first blade 311 and the third blade 313 face each other, and the second blade 312 and the fourth blade 314 face each other, and are formed in a cross shape. Two rows of light emitting lamps 320 are disposed on each of the blades 311, 312, 313, and 314, respectively, but as mentioned above, more rows of light emitting lamps 320 may be disposed.
The light emitting lamps 320 corresponding to the first blade 311 and the light emitting lamps 320 corresponding to the third blade 313 form a long row of light emitting lamps extending in the first direction, in this embodiment, two long rows of light emitting lamps extending in the first direction, and if more rows of light emitting lamps are provided for each of the blades, the number of the long rows of light emitting lamps extending in the first direction is increased accordingly. The light emitting lamps corresponding to the second blade 312 and the light emitting lamps 320 corresponding to the fourth blade 314 form a long row of light emitting lamps extending in the second direction, in this embodiment, two long rows of light emitting lamps extending in the second direction, and if more rows of light emitting lamps are provided for each of the blades, the number of the long rows of light emitting lamps extending in the second direction is increased accordingly. Wherein the first direction is perpendicular to the second direction.
The center P of the long row of cross-shaped light-emitting lamps is provided with four light-emitting lamp beads 321, and the four light-emitting lamp beads 321 are used as public lamp beads of the long row of light-emitting lamps. The four light-emitting lamp beads 321 may all belong to one blade. Or four light-emitting lamp beads 321 are attached to a plurality of the four blades (as shown in fig. 3-5). Or the four light-emitting lamp beads are respectively affiliated to the four blades and close to other light-emitting lamp beads of the corresponding blades (as shown in fig. 6), so that the light-emitting lamp beads on each blade are the same in arrangement structure and distributed around the rotation center O array, and similarly, the screen display at the center position is clearer, and the visual effect is better.
