The effects presented by the building lighting are all achieved through lighting. The lighting angle of each LED light source is fixed, which can only meet a small part of the lighting needs. More lighting effects are achieved through optical lenses. That is, the reflector is realized. Next, the lighting effects and lighting angles of several lamps commonly used in building lighting are introduced.

1. LED line lights are often used to outline the outline of the building. The LED bar screen can achieve animation and linkage effects, and is one of the large-scale light show selection lamps. Lighting height requirements are not high, generally use a flat optical lens, the light-emitting angle is about 120 degrees.

2. LED wall washers are used to illuminate building facades. The lighting distance is short, and there are certain requirements for the lighting height. The single-angle optical lenses are usually 30 degrees, 45 degrees, and 60 degrees. The conventional degrees of double-angle optical lenses are 10*30, 10*45, 10*60 and other angles. The difference between the two is that the double-angle lighting effect is more uniform, and there is no light spot at the bottom of the lighting.

3. LED flood light, used to illuminate the facade of the building, the lighting distance is long, the lighting height is far, the conventional optical lens angle is 30 degrees, 45 degrees, 60 degrees, a beam of light flood light Use 3 degrees, 5 degrees, 8 degrees, 10 degrees and such small angle large lenses to light longer distances.

4. The LED point light source can be used to outline the outline of the building, embellish the wall, or be used as a screen to achieve animation effects and linkage effects. The lighting height is not required, and the lighting angle is 120-160 degrees. Through the flat PC cover and the convex PC Check the lighting angle.
