With the spread of novel coronavirus pneumonia worldwide,
Ultraviolet disinfection lamps and lanterns have become hot sterilization products,
It can meet the needs of lighting and sterilization at the same time
Uvc-led health lighting has become a new favorite in the market.
New Coronavirus (COVID-19) is sensitive to UV and heat. Ultraviolet rays can destroy the molecular structure of DNA or RNA in the cells of microorganisms and make them lose their replication function, so as to achieve bactericidal effect.
The experimental results show that: 1
Ultraviolet radiation with wavelength less than 320 nm can kill microorganisms.
At present, there are two technical products of UV sterilization technology, which can be divided into low-voltage UV sterilization mercury lamp products and deep UV LED products.
Deep UV LED products, namely uvc-led,
The main wavelength of the bactericide is 270-280 nm,
The service life is usually more than 20000 H,
It is more than 5 times of traditional UV mercury lamp,
It has the advantages of small volume, fast start-up speed,
Without preheating, the light energy is concentrated,
It is convenient for intelligent control and can be designed according to different requirements,
It is suitable for a wide range of application scenarios,
Compared with UV mercury lamp, it has higher application flexibility.
The tube type ultraviolet light produces ozone,
Ventilation for half an hour after use,
So it is not suitable for common public places.

Especially with the increase of the optical power of UVC led,
The cost is significantly reduced,
The problem of heat dissipation is improving day by day,
It is gradually replacing traditional UV mercury lamp.
On the basis of the integrated design of uvc-led lighting lamps, the working principle of microwave induction, light control function, delay circuit and emergency power supply is comprehensively used to construct the integrated working mode of lighting and sterilization, so as to avoid the accidental opening of ultraviolet sterilization function while lighting.
