At the present time, LED Lighting has been widely applied in outside areas. Therefore, how to choose the design of LED fixture becomes the primary problem that people should be considered.
First, according to the light distribution and illumination requirements of the places make sure the installation areas of fixture.
Secondly, calculate the luminous flux so that to confirm the quantity and power of fixture.
Finally, ensure the beam angle of fixture (such as LED flood light) by point-by-point method and figure out the illuminance value that needs. In order to the convenience of design, the illuminance value of outdoor is always based on the illuminance level. But in other occasion, it often needs to see the target in vertical clearly. Therefore, we must know the proportion between horizontal illuminance and vertical illuminance. Generally speaking, when the installation height is a little low or the beam angel is a little large, even though the vertical illuminance is increased, it would also produce glare.
With the continuous change of our ideology and lifestyle, there is a large variation in fixture, material, style and design method. When choose suitable lighting source, except for economical factor, we should consider the whole lighting effect and material texture, including the integration between natural environment and lighting.
