flood lights for sale

A flood lighting system comprising a flood lights for sale having a built-in lamp for lighting a building, a polarizer adapted to linearly polarize radiation from the lamp, and an analyzer disposed in such a manner that its direction of oscillation of light is at right angles with that of the polarizer. Thus, the radiation from the flood light does not enter the field of the view of one who looks out from the interior of the building.
As illustrated in FIG. 6, it is a conventional practice to install a plurality of flood lights 1 around a building of historical note or a building serving as a landmark and to illuminate the exterior of the building with these devices during the night hours. This practice is commonly known as " light-up." A building which is lit in this manner appears as a clear silhouette in the nighttime sky, thus producing a picturesque landscape for those viewing the building from the surroundings.

However, when one within such a building (2) looks out from a window (3) during the light-up time, the light from a flood light may be incident on the eye. This may cause a glare or, in extreme cases, impair one's visual acuity.

To alleviate this phenomenon, it has been proposed that the angle of incidence with the normal be decreased by installing the flood light at the foot of the building. Alternatively, it has been proposed that the angle of incidence with the horizontal be decreased by installing the flood light sideways with respect to the window. However, if the angle of incidence is decreased, either with respect to the normal or with respect to the horizontal, the efficiency in lighting the building (the ratio of the brightness of the building to the projected light flux) tends to decrease, with the result that the freedom of choice in the angle of incidence with the normal or the horizontal was naturally limited.

OBJECTS AND SUMMARY OF THE INVENTION

It is a primary object of the invention to prevent entry of light from a flood lights for sale into the field of view of a person who looks out from the window of a building during a light-up time and to eliminate limitations on the installation position of the flood light in regard to the angle of incidence of light with the normal or the horizontal. Thus, it is an object of the invention to allow the flood light to be installed in the position from which the exterior of the building can be lit with the highest possible efficiency.

It is a further object of the invention to reduce the surface reflectance of the window pane of a building and thereby prevent occurrence of the phenomenon in which the window pane alone is visible in reflected light.

It is still another object of the invention to light up a building effectively with an ordinary flood light without providing the flood light with a polarizing means.

It is still another object of the invention to reduce the attenuation of light passing through the window of a building and thereby insure a bright outward look to the building.

It is still another object of the invention to insure linear polarization of light by means of a special lamp and reflector and thereby eliminate the need for installation of a separate polarizing means.

The above-mentioned objects are accomplished by the present invention. The present invention is, therefore, directed to a flood lighting system comprising a flood lights for sale having a lamp and a reflector as built therein for lighting the exterior of a building, a polarizer adapted to linearly polarize an emission light from the flood light and an analyzer installed in a position such that the direction of oscillation of light is at right angles with respect to the polarizer. The polarizer and analyzer are installed in an optical path from the lamp to a window of the building to prevent entry of the radiation from the flood light into the field of view of a person who looks out from the window.

In a preferred embodiment of the present invention, the polarizer polarizes the light linearly in a horizontal direction to reduce the surface reflectance of a window pane. In another embodiment, the polarizer is installed in front of the flood light and the analyzer is installed at the window of the building. More particularly, the analyzer is installed at the window to be lit, 1 to 2 meters above flood level, so that the radiation from the floor light will not enter the eye of a person in the building.

In another embodiment, the polarizer is installed so it extends outward from the lower edge of the window in a plane perpendicular to a straight line interconnecting the flood lights for sale with the vertical center of the window and over the range defined by the included angle 2a between a straight line interconnecting the flood light with the upper edge of the window and a straight line interconnecting the flood light with the lower edge of the window. In this arrangement, even when an ordinary flood light is used, the radiation from the flood light is not incident on the eyes of one who looks out from the window of the building.

In still another embodiment, the polarizer is disposed in front of the lamp and the analyzer is installed so it extends outward from the lower edge of the window over the range defined by the included angle between the line interconnecting the flood light with the upper edge of the window and the line interconnecting the flood light with the lower edge of the window, whereby the loss of light flux is decreased.

In a further embodiment, a flood lights for sale comprising a linear tubular lamp and a trough-shaped reflector for projection of a linear polarized radiation is employed. Here, the analyzer is installed in an optical path from the flood light to the building to be lit. Thus, the radiation from the flood light may be prevented from entering the eyes of one who looks out from the window without requiring an independent polarizing means.
