High   Bay Lights Sensor 200 Watt Equivalent Led Industrial High Bay Led Shop Lights , Ultraviolet disinfection lamp, the ultraviolet ray that USES mercury lamp gives off, achieve the purpose that disinfects sterilization. It has the characteristics of high radiation intensity and good disinfection effect, and is widely used in the hospital laboratory and catering industry. Ultraviolet disinfect lamp should use correctly, can bring more serious harm otherwise. Common harm has: 1, the harm to the skin.Exposure to ultraviolet disinfection lamp, the skin can cause redness, pain, flaky change.If irradiated for a long time, it may cause skin cancer and skin tumors.Two, the damage to the eye, ultraviolet disinfection lamp can cause conjunctivitis of the eye, keratitis, the eye appears the phenomenon of red and swollen, ache, tear, apply for a long time, very likely can cause cataract.So, when using ultraviolet ray disinfection lamp, do not have someone inside the room as far as pos...

Ultraviolet (UV) has a wavelength range between X-ray (≤100 nm) and visible light (>Between 400 nm), in the range of about 100-400 nm.According to the interaction between ultraviolet ray and molecule, LED Ufo Grow Lights ,  it can be divided into four types, which have different physiological effects on substances.Vacuum UV (VUV) has a wavelength range of 100-200 nm. At low doses, it can also react immediately with oxygen and organic molecules, which can be harmful. Ultra-short ultraviolet (UVC) wavelengths range from 200 to 280 nm.UVC is completely absorbed by the atmosphere and no natural UVC rays reach the earth's surface.Ultraviolet light at this band has a bactericidal effect.The active "ingredient" in what is commonly referred to as "ultraviolet sterilization" is UVC[2], which can be obtained from artificial light sources (such as UVC leds or mercury lamps).The penetration capacity of UVC is weak, most of it will be absorbed by the cuticle and epid...

Ufo LED Grow Lights One is that ultraviolet light has an effect not only on bacteria, but also on mammalian cells.The second is that bacterial spores are highly resistant to ultraviolet light, which is somewhat worrying.The dormant spores of bacillus subtilis, for example, are five to 50 times more resistant to ultraviolet radiation than the corresponding growing cells. Spore photoproduct lyase (spore photoproduct lyase) is a unique DNA repair enzyme that makes spores so resistant.During endospore germination, SP lyase can repair DNA damage induced by ultraviolet radiation.Bacterial spores are highly resistant to physical damage such as heat, ionization, ultraviolet and gamma radiation, osmotic pressure, and dryness.Spores also protect bacteria from chemical and biological disinfectants such as iodine, peroxides, and alkylating agents.So even crude physical and chemical methods can't get rid of bacterial spores.The so-called wildfire burn, the spring breeze is born.Therefore, ...

LED Stadium Lights , LED high-power chips used for white light are generally around 40mil in the market. The so-called high-power chips generally use power of more than 1W. Since the quantum efficiency is generally less than 20%, most electric energy will be converted into heat energy, so the heat dissipation of high-power chip is very important, requiring a large area of chip. What are the different requirements of chip process and processing equipment for GaN epitaxial materials compared with GaP, GaAs and InGaAlP?Why is that? Common LED red and yellow chips and highlighted four-element red and yellow chip substrates are made of GaP, GaAs and other compound semiconductor materials, which can generally be made into n-type substrates.The wet process was used for lithography, and then the silicon carbide wheel blade was used to cut the chip.The blue and green chip of GaN material is a sapphire substrate. As the sapphire substrate is insulated, it cannot be used as a pole of LED. Tw...

So what are its features?The main purpose of LED chip manufacturing is to produce effective and reliable low ohmic contact electrode, and can meet the relatively small pressure drop between the contactable materials and provide the pressure pad for welding line, while as much light as possible.Transfer process generally USES vacuum evaporation method, 4Pa high vacuum, resistance heating or electron beam bombardment heating method to melt the material, and at low pressure BZX79C18 into metal vapor deposition on the surface of the semiconductor material. In general, the p-type contact metals used include AuBe, AuZn and other alloys, and the contact metals on the n-side usually use AuGeNi alloy.The alloy layer formed after coating also needs to expose the luminous area as much as possible through the lithography process, so that the remaining alloy layer can meet the requirements of effective and reliable low ohm contact electrode and welding line pressure pad.After the photolithogra...
