Title:
WIND POWER GENERATING LIGHTING FIXTURE
Document Type and Number:
Japanese Patent JP2005228639
Kind Code:
A
Abstract:

To provide a wind power generating lighting fixture capable of utilizing effectively energy of electric power generated by performing a control, according to the characteristics of wind power generation, and thus extending the lighting hours of a lighting fixture.

A wind power generating lighting fixture includes a wind turbine generator 3, a lead accumulator 4, a lighting fixture 5, a solar cell 6 or EE switch 7, a controller 8, a first switch 9 provided between the wind turbine generator and the controller, and a second switch 10 and a third switch 11, provided in series between the lighting fixture and the controller. The controller 8 discriminates the daytime and nighttime from the converted voltage of the solar cell 6 and the EE switch 7, and transmits the ON instruction to the first switch 9, if the charge amount of the lead accumulator is at an upper limit value; while transmitting OFF direction to the second switch 10, if the charge amount of the lead accumulator reaches an lower limit value, and transmitting the OFF instruction to the third switch 11 in the case of daytime. A brake mechanism 2 is activated, if the first switch 9 is at ON position.
