Self-electricity-generating leading-wire-free LED indicating board

The utility model discloses a self-electricity-generating leading-wire-free LED indicating board which comprises a photovoltaic chip, SMD LED lamps, a bonding layer and a packaging layer. The photovoltaic chip is connected with the SMD LED lamps. The bonding layer bonds the photovoltaic chip, the SMD LED lamps and the packaging layer. Multiple laser lines are engraved on the photovoltaic chip in the transverse direction regularly, and multiple insulating bands formed by multiple insulating lines are engraved in the longitudinal direction regularly or irregularly. The insulating bands divide the photovoltaic chip into multiple communicated electricity generating areas. The SMD LED lamps are arranged on the insulating bands. According to the self-electricity-generating leading-wire-free LED indicating board, the interior of the chip is connected in the mode of engraving the insulating lines through laser, the SMD LED lamps are then attached to the insulating lines, the chip can form a circuit, under the condition that illumination is available, electricity generated by the chip enables the LED lamps to emit light, in the whole process, aluminum bands, copper bands and other wires are not used for connection, and the product is simple and attractive.
