UFO floodlight glass lenses improve lighting effects and even light distribution. The design of glass lenses can affect the shape, intensity and uniformity of the light beam.
\nGlass lens types include:
\n1. Condenser lens: It can focus light into a more concentrated beam, suitable for occasions requiring high brightness.
\n2. Astigmatism lens: It can scatter light to make the lighting more uniform, suitable for large-area lighting needs.
\nWhen choosing a UFO floodlight glass lens, the following factors should be considered:
\nLight transmittance: Lenses with high light transmittance can maximize the utilization efficiency of light sources.
\nWeather resistance: If used outdoors, it is recommended to choose lenses with good weather resistance to prevent the influence of ultraviolet rays, moisture and temperature changes.
\nImpact resistance: Consider whether it is necessary to choose impact-resistant materials to deal with potential physical damage.
\nUFO floodlight lenses made of optical glass have the following characteristics:
\n1. 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
