SUN TRACKING LIGHTING DEVICE

摘要

The invention provides a light admitting device of the sun tracking type which has a solar cell as mounted on light reflecting means for tracking the sun. This arrangement assures the solar cell of an improved power generation efficiency without making the device greater in size and more complex. The device comprises a dome (20) made of a light transmitting material, light reflecting means (30) covered with the dome (20) and rotatably supported within the dome (20), drive means (60) coupled to the light reflecting means (30) for rotating the light reflecting means (30) to orient this means (30) toward the direction of the sun, rechargeable power source means (43) electrically connected to the drive means (60) for supplying electric power to the drive means (60), and a solar cell panel (40) electrically connected to the power source means (43) for charging the power source means (43). The solar cell panel (40) is disposed within the dome (20) so as to be rotatable with the light reflecting means (30).
