LED HD display solutions reduce light pollution

Changsha LED display, LED display, LED screen manufacturers, LED screen customization, LED screen LED HD display customized solutions to reduce light pollution. To reduce light pollution led high-definition display, the best method is to control the light distribution of the light direction and light energy. That is, within the effective visual range, all is light, the light energy necessary to focus as much as possible within the effective visual range. Invalid range in visible light is harmful light, the need to minimize light energy distribution in the visible range is invalid, so as to achieve the goal of reducing light pollution. LAMP asymmetric optical devices designed to reduce light pollution. Display is usually installed in certain height, and perpendicular to the horizontal installation, people usually look up to watch the display, under the perspective of the effective visual range, the viewing angle is invalid visible range, can cause serious light pollution. In order to save energy and reduce light pollution purposes, in accordance with the usual bottom outdoor led display application environment and viewing habits, LAMP presented the idea of ??asymmetric optical devices. By LAMP devices asymmetric optical design on the part of the energy perspective, transferred to the next perspective visual range, thereby increasing the viewing angle to within visual range of the effective brightness, while reducing the light pollution within visual range perspective invalid purposes. Perspective invalid reducing light pollution in the visible range. Effective viewing perspective in the lower brightness range is effective brightness, asymmetric LAMP LAMP than normal brightness better. Invalid lower brightness within the viewing angle range of visual brightness is harmful asymmetric luminance LAMP be as small as possible, the invalid light pollution can be reduced visible range. When the horizontal 0 ° viewing angle luminance values ??are the same, the next perspective invalid visible range, when the horizontal angle greater than ± 60 °, asymmetrical AB Series LAMP device brightness decreasing rate housing, far higher than the normal decline LAMP device box speed, so the cabinet brightness asymmetric LAMP LAMP box below normal brightness, viewing angle is below the visible range invalid, asymmetric light pollution than normal device LAMP LAMP light pollution devices. Reducing the perspective of invalid within the visible range of light pollution. In order to compare the device with normal asymmetric LAMP LAMP light pollution devices in the visible range of the viewing angle is not valid, the asymmetric cabinet with normal LAMP LAMP device cabinet power adjustment for the same device, the viewing angle within the range of brightness under different angle looking up were compared. Within the range of viewing angles, from an asymmetric luminance normal LAMP LAMP box casing brightness contrast, the optical design of the asymmetric LAMP device, in plan view different angles, light pollution can be reduced by 10% to 50%.
