The protective plate 13 may be made of a rigid material, and may not deform the surrounding protective plate 13 when folded. This application is higher than banks 12 through protection shield 13 around banks 12 and height, when folding flexible illuminator 10 along folding district 111, because protection shield 13 is peripheral at banks 12, is difficult for causing the influence to the installation of banks 12, and higher protection shield 13 can protect banks 12 upper surface.

So set up, then when folding, protection shield 13 just overlaps with fretwork hole 114 and sets up, does benefit to the heat dissipation of LED banks 12.

N is a natural number greater than or equal to 1. For example, if N is 3, the length of each of the three protection plates 13 along the first direction X and the length of each of the hollow holes 114 along the first direction X are equal. It is understood that N may be 1, 2, 4 or more than 4 in other embodiments, and is not particularly limited herein.

The lamp set 12 is installed in the working area 112 by welding, for example, the first lamp bead 121, the second lamp bead 122 and the third lamp bead 123 are all installed in the working area 112 by welding. Protection shield 13 also installs in workspace 112 through the welded mode, when folding district 111 is folding to be extended, probably can exert an influence to workspace 112, leads to protection shield 13 welding on workspace 112 insecure, but can not influence first lamp pearl 121, second lamp pearl 122 and third lamp pearl 123 to play the guard action to first lamp pearl 121, second lamp pearl 122 and third lamp pearl 123.
