Floodlights Can Illuminate The Roof

In the context of the city, it is often not possible to install the floodlights in an ideal location. Should be adjusted at the scene based on the initial design of the lighting design in order to take into account the physical limits of the location and achieve the most satisfactory solution, such as taking into account the appearance of the fluorescent lamp, glare, maintenance and adjustment of the entrance.

The width of the beam produced by the floodlight may be larger or smaller depending on the position adjustment of the optical system and the light source in the lamp. Conventionally, Flood Light the beam range of the floodlight is determined by the direction of the luminous intensity equal to 50% of the peak luminous intensity in the axial direction of the beam.

The beam range of the circular symmetrical floodlight is constant on each face, and the beam range of the rectangular floodlight is usually oval, which is determined by two values corresponding to two symmetry planes.

In some applications, the light beam used is asymmetrical in the case of peak light intensity. In this case, the beam range is equal to 50% of the light intensity determined by the two half angles.

Since the beam range of many floodlights is narrow, the curves in polar coordinates in Figure 3 can not be read or inaccurate. In general, if XY is used, where the vertical axis OY represents the illuminance and the horizontal axis OX represents the angle of the beam. In most floodlights, Flood Light the light source that transfers the optical system will change the shape of the distribution curve (beam range, light intensity, and symmetry).

In order to be able to see the circle of the tower, the width of the tower should be constantly changing the brightness. However, the fiber should remain on the vertical line. The floodlights are arranged in accordance with Figs. 5A and 5B. The change depends on the ratio of the distance between the object to the object and the diameter of the tower.

When the ratio is high, that is, when the narrow tower is illuminated by a distant floodlight, it is appropriate to arrange two floodlights according to Fig. 5A. When the floodlights are installed in the vicinity of the building, Flood Light three sets of floodlights should be arranged according to Figure 5B for the low tower, with an angle of about 120 ° from each other.

When you can only see a large diameter column from one direction, you may have two effects. It is possible to create an illuminated central area between two dark areas (Figure 5B / 5D / Figure 5E) or to reverse the arrangement depending on the characteristics of the building background.

The roof is usually made of a material that is darker than the inside, so its brightness is low, even during the day. In order to maintain balance, the illumination of the roof lighting can not be higher than the other parts of the building. If the color of the roof is conspicuous, Flood Light this effect can be enhanced by using a light source with the appropriate primary color.

It is often not possible to illuminate the roof from the same location when the floodlight illuminates the facade. In towns, floodlights can usually be installed on adjacent buildings. In other cases, the floodlights can be mounted on a mast or roof on a corresponding distance.

If the floodlights are to be installed on the roof, it is important to note that these floodlights are to be installed in a shelter to keep the building

Aesthetics. Skylights, windows, Flood Light drainage systems, chimneys and other buildings can provide the location to install and conceal floodlights. Installing the floodlight on the edge of the roof platform makes it easy to illuminate the facade above the platform

When the building lighting is provided by a floodlight installed at about twice the height of the elevation, the beam of light is usually able to illuminate the roof
