Abstract
An outdoor light fixture for use with a specifically selected gas discharge lamp which emits a predetermined light of wavelengths that are least visible to sea turtles but visible to humans which adequately illuminates outdoor human living spaces for safety without harming sea turtle nesting activity. The light fixture includes an illumination tube having a specifically selected gas discharge tube, power supply circuitry having a first and second transformer and bridge rectifier for low and high voltage control, and a lamp housing.
Claims5
The method of illuminating outdoor areas for human safety and to protect turtle nesting comprising the steps of:
- a) installing an outdoor light source in outdoor areas used by humans having a wavelength between 680 nm and 780 nm that is least harmful to turtle nesting;
- and
- b) illuminating said light source during darkness for human safety without disturbing turtle nesting.
An outdoor light source observable to humans for mounting where sea turtle nesting occurs comprising:
- an illumination gas discharge tube emitting light of wavelengths between 680-780 nm which are not observable to sea turtles when energized;
- a transparent protective tube cover which encloses said illumination gas discharge tube;
- power supply circuitry having a first and second transformer and a bridge rectifier, the first transformer and bridge rectifier electrically connected for reducing 110 volts AC to 12 volt DC, the second transformer stepping up voltage to 7000-9000 volts DC for energizing said illumination tube;
- and
- a lamp enclosure fixture for enclosing, said illumination gas discharge tube and said second transformer mounted therein, said fixture having an aperture directing light towards a small intended area to be lighted below said lamp, while minimizing direct and indirect lighting of the nearby horizon as well as preventing direct visibility of said illumination tube from the nearby horizon.
