led high bay light emitting angle: refers to the emitting angle of the diode, that is, its light scattering angle is mainly controlled by adding a scattering agent during the production of the diode. It is also affected by the lens and lampshade.
Lens: It is the secondary light distribution. The lens angle refers to the size of the luminous range of the LED product after lighting, which is called the beam angle. Reflecting the light source with the same spot size and intensity on the illuminated wall, the smaller the beam angle, the larger the center light intensity, the smaller the spot, and the better the light effect. At present, the common beam angles on the market are: 15°, 25°, 45°, 60°, 90°, 120°. According to the angle, they can be divided into: narrow-angle beam: 20°﹥, medium beam 20°-40°, Wide beam > 40°. Led high bay light are generally wide beams, and most of them will choose 90° or 120°. Individuals with light intensity requirements will choose 60° or 45°. The specific design will take into account the installation height, installation distance, illumination requirements and other parameters to choose.
Lampshade: The lampshade of the ufo led high bay light we see on the outside actually has a certain function of focusing and adjusting the beam angle.
