Patent ID: 8016454

Claim:
A light emitting diode illuminator, comprising: at least one light source; and a receiving seat comprising a panel and a back plate assembled to the panel, at least one receiving chamber, corresponding to the at least one light source, defined between the panel and the back plate, each of the at least one receiving chamber defining an opening at a lateral side of the receiving seat and an aperture, each of the at least one light source being mounted into one of the at least one receiving chamber via the opening of the receiving chamber and capable of emitting light via the aperture, a block extending outwardly from the back plate to the opening of each of the receiving chamber to prevent the one of the at least one light source from falling out from the one of the at least one receiving chamber of the receiving seat; wherein, to define each of the at least one receiving chamber, the back plate comprises a flat wall spaced from the panel, a pair of flanges extending from two opposite sides of the flat wall to the panel, and a hem extending transversely from each flange, the hem engaging with the panel to assemble the back plate to the panel, the receiving chamber being formed between the flat wall and the panel, the receiving chamber being open at the other two opposite sides of the flat wall without the flanges; wherein each of the at least one light source comprises a transparent plate, a light emitting diode array arranged at a side of the transparent plate, and a fastener fixing the light emitting diode array to the transparent plate; wherein the fastener includes a vertical plate, a pair of aslant plates extending transversely from top and bottom sides of the vertical plate, respectively, and a pair of parallel plates extending from the aslant plates, the transparent plate being sandwiched between the parallel plates, the light emitting diode array being received in the fastener and located between the aslant plates; and wherein the light emitting diode array comprises a mounting base, and a plurality of light emitting diodes arranged at an inner side of the mounting base and facing the transparent plate.
