How to calculate the safety of the light

always focus on our website friends of light, all know, today small make up to you to introduce the safety of the light, calculation, below we will simply look at together. 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. 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, LED street light, the unit KG/M3. V for wind speed, the unit is M/S. R for severe air, unit KN/M3. Today's content is introduced here, thank you for reading. If you have this need, please call our hotline. Small make up: Nicole
