  • Light-emitting device with spherical photoelectric converting element
    Patent number: 7387400
    Abstract: A light-emitting device has spherical photo-electric converting elements that have a substantially spherical acceptance surface, respectively; a light emitting diode powered by the spherical photo-electric converting elements; a control circuit; and a sealing member that integrates the spherical photo-electric converting elements, the light emitting diode and the control circuit. The control circuit is equipped with a light emitting control circuit including a photo-detecting sensor, a charge control circuit and a condenser.

  • Selfluminous device
    Publication number: 20060133073
    Abstract: A self light-emitting device 1 has spherical photo-electric converting elements 2 that have a substantially spherical acceptance surface, respectively; a light emitting diode 3 that emits light using electric power generated by the spherical photo-electric converting elements 2; a control circuit 5; and a sealing member 4 that integrates the spherical photo-electric converting elements 2, the light emitting diode 3 and the control circuit 5. The control circuit 5 is equipped with a light emitting control circuit where a photo-detecting sensor 23 is incorporated, a charge control circuit and a condenser. Since the acceptance surface of the spherical photo-electric converting elements 2 is substantially spherical, electric power is generated due to incidental light from any angle. Since the sealing member 4 integrates the constructional elements, so the device is difficult to damage.
