A selfluminous device (1) comprising a spherical photoelectric converting element (2) having a substantially spherical light receiving surface, a diode (3) emitting light with power generated from the spherical photoelectric converting element (2), a control circuit (5), and a sealing material (4) for integrating the spherical photoelectric converting element (2), the light emitting diode (3) and the control circuit (5). The control circuit (5) comprises an emission control circuit incorporating a photosensor (23), a charging control circuit, and a power storage unit. The spherical photoelectric converting element (2) can generate power with an incident light from any angle because it has a substantially spherical light receiving surface. The selfluminous device (1) can be protected against damage because the constituent members are integrated through the sealing material (4). |
