UVC deep UVC germicidal lamp with what material to do better
Recently, there are often friends ask about UVC germicidal lamps, what kind of UVC lamp to kill the new coronavirus? Are you still worried about finding a reliable quality LED germicidal lamp beads? It is not that difficult to identify the good or bad LED germicidal lamp beads, we usually use most of the UVC type of UVC disinfection lamps, the main wavelength of 253.7nm, this wavelength of ultraviolet light can act on the genetic material of the DNA of the organism, so that DNA is damaged, resulting in the loss of virus survival and replication capabilities. The inactivation time through the UV lamp is between 15-35 minutes. UVC has the function of bacterial inhibition, but only in the 200-280nm wavelength band of ultraviolet light to have this function.
The current market UVC lamp beads can be applied in the food preservation, air purification, water purification and other markets, the potential demand is amazing. At present, the domestic antibacterial disinfection new UVC led light beads, 280nm wavelength of deep ultraviolet light. Specifications are as follows: including 2-3mw, 4-6mw, 10-12mw of three, new mass production 280nm deep ultraviolet UVC germicidal disinfection LED light-emitting diodes, germicidal effect beyond the previous. Peak wavelength: 280nm package size: 3535; voltage: 6.0V, current: 30mA, electrical power: 200mW, optical power: 1.8mW, lens: quartz glass flat lens, light angle: 130°. UVCLED also has a number of applications, including medical analyzers, water purifiers, air-cum-surface sterilizers, surface-cum-medical sterilizers, air purifiers, home appliances Sterilization and other markets.
UV germicidal lamp lens aspect, you should choose quartz glass, high temperature resistance, thermal expansion coefficient is very small, good chemical stability, bubbles, streaks, uniformity, birefringence and can be comparable to the general optical glass, so it is working in a variety of harsh occasions with high stability optical coefficient of essential optical materials. The glass tube is made of high purity quartz glass. Therefore it has a high UV transmission rate, which produces a very high output of UV radiation. In the same specifications by the same ballast test, quartz glass germicidal lamp UVC intensity is more than 1.5 times that of high boron glass germicidal lamps.
1、High temperature resistance. The softening point temperature of quartz glass is about 1750℃, which can be used for a long time at 1100℃, and the short time high use temperature can reach 1450℃.
2 、Good thermal stability. Adaptation of the coefficient of thermal expansion of the glass is very small, can withstand drastic temperature changes, the quartz glass heated to about 1100 ℃, into room temperature water will not blow up.
3、Good light transmittance performance. Quartz sheet in the ultraviolet to infrared spectrum of the entire band have good light transmission performance, visible light transmission rate of 93% or more, especially in the ultraviolet spectrum area, the large transmission rate of up to 95% or more.
Our company's self-developed products are all 254nm, using high-grade quartz glass to ensure the effectiveness and stability of UVC lamps. Welcome to contact in order to get the latest style and price!
