The application of non-yellowing glass lens in UFO floodlight is mainly reflected in its superior optical performance and durability. Here are some specific application advantages and features:
Excellent optical transmittance: non-yellowing glass lens can effectively transmit more light, providing higher brightness and clearer lighting effects. This is very important for UFO
floodlights because they are often used in occasions that require high-brightness lighting.
Strong weather resistance: non-yellowing glass materials usually have good weather resistance and can resist the damage of ultraviolet rays, moisture and other environmental factors, thereby
ensuring that the lamps maintain good performance for a long time. This allows UFO floodlights to be used in outdoor environments without fading or aging.
Color stability: Compared with other types of lenses, non-yellowing glass lenses will not change color after long-term use, can maintain the true color of the light source, and ensure the
consistency of lighting effects.
Excellent thermal stability: non-yellowing glass lenses can still maintain their structure and performance under high temperature conditions, and are suitable for high-power UFO floodlights.
Impact resistance: This type of glass lens is usually more impact-resistant, can protect the internal components of the lamp in harsh environments, and increase the service life of the lamp.
Aesthetics: The non-yellowing transparent effect can enhance the appearance of the UFO floodlight, making it more modern and technological, and meet the user’s dual needs for beauty and
function.
In summary, the non-yellowing glass lens can provide higher performance and reliability in the application of UFO floodlights, making it an ideal choice in lighting equipment design.
The glass lens connecting plate design breaks through the traditional PC connecting plate lens used in the module, bringing a new experience and effectively overcoming the undesirable problems of
PC lenses:
Corrosion resistance: High borosilicate 3.3 glass belongs to borosilicate glass in borosilicate glass, which is acid and alkali resistant and has excellent corrosion resistance.
Strong temperature resistance: Compared with PC lenses, it has a lower thermal expansion coefficient, good thermal stability, small changes in optical surface temperature, and retains the
original optical lighting effect.
High light transmittance: The light transmittance of conventional PC lenses is about 85%, resulting in a waste of light. The light transmittance of glass lenses is 92-94.8%, and can be as high
as 97% after being coated with an anti-reflection film.
Compared with PC lenses, glass lenses will not age/yellowing, which will affect the light transmittance of the lens.
Compared with PC lenses, glass lenses will not absorb dust and are easy to clean.
Quartz glass is a special industrial technical glass with a single component of silicon dioxide. This kind of glass has a hardness of up to Mohs level 7, has high temperature resistance, low expansion coefficient, thermal shock resistance, chemical stability and good electrical insulation performance, and can transmit ultraviolet and infrared rays. Except for hydrofluoric acid and hot phosphoric acid, it has good acid resistance to general acids. According to transparency, it is divided into two categories: transparent and opaque. According to purity, it is divided into three categories: high purity, ordinary and doped.
High borosilicate glass is made by heating the glass to melt it under high temperature conditions. It is processed by production technology. Because the linear thermal expansion coefficient is (3.3±0.1)*10-6/K, it is also called “borosilicate glass 3.3”. It is a special glass material with low expansion rate, high temperature resistance, high strength, high hardness, high light transmittance and high chemical stability. Due to its excellent performance, it is widely used in solar energy, chemical industry, pharmaceutical packaging, electric light source, craft accessories and other industries.
The main differences between quartz glass and high borosilicate glass are as follows:
Ingredients
Quartz glass: The main component is silicon dioxide (SiO₂), and the purity is generally above 99%.
High borosilicate glass: The main components include silicon dioxide, boron trioxide, sodium oxide, potassium oxide, etc., among which the content of boron trioxide is relatively high, generally above 12%.
Performance characteristics
Hardness: Quartz glass has high hardness, with a Mohs hardness of up to 7, second only to diamond, corundum and other materials. High borosilicate glass has a relatively low hardness, with a Mohs hardness of about 5.5.
Heat resistance: Quartz glass has extremely high heat resistance and can be used for a long time at a high temperature of about 1100℃ without softening or deforming, and can withstand higher temperatures in a short period of time. High borosilicate glass also has good heat resistance and can withstand a temperature difference of about 300℃. It can be used at relatively high temperatures, but not as good as quartz glass.
Corrosion resistance: Quartz glass has extremely strong corrosion resistance. It hardly reacts with other acids except hydrofluoric acid and hot phosphoric acid, and it also has strong corrosion resistance to alkali substances. High borosilicate glass also has a certain tolerance to acids, alkalis and other chemicals, but not as good as quartz glass.
Appearance
Transparency: Quartz glass has extremely high transparency, and has high transmittance to ultraviolet light, visible light, and infrared light. High borosilicate glass also has good transparency, but slightly lower than quartz glass.
Color: Quartz glass is usually colorless and transparent, but some metal oxides and other substances can be added during the manufacturing process to make it present different colors. High borosilicate glass is generally colorless or slightly green.
Manufacturing process
Quartz glass: The manufacturing process is relatively complicated, mainly including electric melting method, gas refining method, etc. Due to the high melting point of quartz glass, the manufacturing process requires high temperature and special equipment.
High borosilicate glass: The manufacturing process is relatively simple, usually using traditional glass manufacturing methods such as float method, crucible method, etc.
Led glass lens is an optical element used for LED light sources. It focuses, diverges or evenly distributes the light emitted by LED through special design and materials, thereby improving the efficiency and effect of the light source. Its main features include:
Optical performance: Glass lenses can effectively control the direction and intensity of light and improve lighting effects.
Durability: Compared with plastic lenses, glass materials have better temperature resistance and wear resistance, and are not easily deformed.
Low light loss: High-quality glass lenses can reduce light reflection and absorption, maximizing the use of light emitted by LEDs.
Diversity: Can be designed into different shapes and curvatures according to different lighting needs, such as spherical lenses, aspheric lenses, etc. Application areas include but are not limited to indoor lighting, outdoor lighting, automotive lighting, etc. By properly configuring LEDs and glass lenses, lighting quality and effects can be significantly improved.
