Improve lighting effect and uniform light distribution. The design of the lens can affect the shape, intensity and uniformity of the beam.
\nSome common lens types include:<\/p>\n
1. Condenser lens: It can focus light into a more concentrated beam, suitable for occasions requiring high brightness.<\/p>\n
2. Astigmatism lens: It can scatter light to make the lighting more uniform, suitable for large-area lighting needs.<\/p>\n
When choosing a UFO floodlight glass lens, consider the following factors:<\/p>\n
-Transmittance: Lenses with high transmittance can maximize the utilization efficiency of light sources.<\/p>\n
-Weather resistance*: If it is used outdoors, it is recommended to choose a lens with good weather resistance to prevent the influence of ultraviolet rays, moisture and temperature changes.<\/p>\n
-Impact resistance: Consider whether it is necessary to choose an impact-resistant material to deal with potential physical damage.<\/p>\n
UFO floodlight lenses made of optical glass have the following characteristics:<\/p>\n
1. Corrosion resistance: High borosilicate 3.3 glass belongs to borosilicate glass among borosilicate glass, which is acid and alkali resistant and has excellent corrosion resistance.
\n2. Strong temperature resistance: Compared with PC lens, it has a lower thermal expansion coefficient, good thermal stability, small change in optical surface temperature, and retains the original optical lighting effect.
\n3. High transmittance: The transmittance of conventional PC lens is about 85%, resulting in a waste of light. The transmittance of glass lens is 92-94.8%, which can be as high as 97% after anti-reflection film coating.
\n4. Compared with PC lens, glass lens will not produce aging\/yellowing phenomenon, which will affect the transmittance of lens.
\n5. Compared with PC lens, glass lens will not absorb dust and is easy to clean.<\/p>\n
