Description
Technical field
The utility model relates to the devices in the direction for controlling light, more particularly to improve UVC (short wave ultraviolet light) contact
Light guide glass of area and preparation method thereof.
Background technique
The highest peak of the absorption ultraviolet light of DNA (DNA), ribonucleic acid (RNA) and nucleoprotein in bacterium exists
254~257nm.After bacterium absorbs ultraviolet light, DNA chain is caused to be broken, the crosslinking of nucleic acid and albumen is caused to rupture, kills nucleic acid
Bioactivity, cause bacterial death.When radiation intensity reaches 30mW/cm2, bacterium and virus are killed in 10s.Quickly
It is convenient, because physical contact characteristic without secondary pollution makes UVC have great advantage in the application in sterilization field and widely answers
With.
The UVC light source mainstream of existing application is low pressure mercury lamp, since mercurous and volume is big, is limited in many applications.
The development of LED core chip technology, so that it is environmentally friendly, it is small in size, it is purple (200nm-280nm) using more flexible shortwave
UVC LED starts to enter in disinfection antivirus field practical.But the light penetration capacity of the wave band is very poor, can not penetrate exhausted big portion
The glass and organic optical materials divided, aerial decaying is very big, and UVC LED light power very little, and often light does not reach
It has just been decayed to by dissipation object near nothing.
Volume production or the UVC LED in grinding, electro-optical efficiency is still very low (yield production type < 2% is grinding < 5%),
Mean the UVC LED that single 20mA is lighted, UVC LED its optical power that optical power only has trivial 2mW, 350mA to light
Only 40-70mW, and it is at high price.
The germicidal applications scheme of existing UVC LED is mostly the matrix arrangement based on the packaged LED of simple grain, to obtain foot
Enough sterilization surface power densities
By taking the UVC air purification and disinfection apparatus of the prior art as an example, as shown in Figure 1, being located at the UVC light source of purification tube wall 4
The 3 light strokes for reaching A point are L, and the light stroke for reaching B point is 2L, it is assumed that the radiant power of A point is Pa, in the item of air dielectric
Under part, theoretically, the radiant illumination of light and distance square are inversely proportional, then radiant power Pb=Pa/2 of B point2=Pa/4, i.e. B
The radiant power of point only has the 1/4 of A point；Similarly, the light stroke of D point is also greater than A point, radiant power Pd < Pa；C point just exists
The blind area of two UVC light sources, radiant power can be smaller.Increase the arrangement of UVC LED light for the bactericidal effect that has reached
Density, brings that size increases and cost is substantially increased.
Publication No. be CN103591760A disclose it is a kind of have for the guide-lighting layer frame in refrigerator, the layer frame tempered glass be base
Plate, the plane of substrate are equipped with guide-lighting buckle layer, and substrate is surrounded by molded plastic frame bearing support, illumination, sterilization line style cold light
Source is wrapped in molded plastic frame bearing support, and for this structure due to the tempered glass of use, matrix surrounding side is plastics, guide-lighting
Efficiency is extremely low, therefore this structure bactericidal effect is very little, and plastics can be deteriorated under UVC irradiation quickly and be lost
Function.
