often pay attention to our friends will know that in high lamp light, today small make up to you to introduce high lamp manufacturer security calculations, let's together to simply look at it.

　　1) Light, lamp plate ( Including the lamps and lanterns) The windward area: because of the light plate with different shape, make the lamp panel of windward area is uncertain. Now take common enclosed flying saucer shaped lamp panel as an example, the lamp panel appearance of orthographic projection as the windward side reference area S lamp plate = ( d1+d2) H1/2;

　　2) High light pole of windward area: high light pole body tend to use ( Taper about 1000:5) Cone or cylinder solar led street lamp body. The wind area of the shaft that increases with the increase of shaft length. The body S = ( D1+D2) H2/2;

　　3) Light of the basic wind pressure is perpendicular to the plane of the airflow direction wind pressure calculation by wind pressure, according to the Bernoulli equation that the standard air pressure relationship formula. The wind of the dynamic pressure is: the WP = 0. 5*r*V2/g=0. 5*ro*V2( ro = r / g) WP for wind pressure, the unit KN/M2. Ro for air density, the unit KG/M3. V for wind speed, the unit is M/S. R for severe air, unit KN/M3.
