Abstract: A power supply circuit of dual purpose chargeable accumulator includes a solar cell circuit comprising a plurality of solar energy boards, and a plurality of solar cells, wherein the solar cell circuit is connecting with an output detecting circuit, and the output detecting circuit is capable of detecting an output voltage of the solar cell; an alternating current (AC) circuit; a power selective circuit connecting with the solar cell circuit and the AC circuit; a charge battery; a charge control circuit connecting with the charge battery; a battery voltage detecting circuit connecting between the power selective circuit and the charge battery for detecting a voltage of the charge battery to select or not select the AC circuit to charge the charge battery; and a control circuit for controlling the power selective circuit to select the solar cell circuit or the AC circuit.

Abstract: An illuminating display device is capable of forming multiplex formative and is widely used, which includes a plurality of continuous illuminating units having a shearable solid base, each base forms a concave optical concentrating portion disposed at a surface thereof, and a reflective layer is disposed at a top portion of the concave optical concentrating portion. Each of the illuminating units includes an illuminating member disposed at the reflective layer, and each of the illuminating units may be series or parallel connected. With these configurations, the user may shear the illuminating display device at different patterns according to the needs. The reflective layer may improve the utilization efficiency and increase the identifiable distance of the illuminating display device, which enable the illuminating display device to be widely used in advertisements, texts, logos, road billboards, license plate, or the like.
