Description

Collection beam UVLED ultraviolet scanning device

This creation is about a focused beam UVLED ultraviolet scanning device. The device mainly uses a focused beam UVLED lamp to provide high-dose radiation intensity. After scanning, it expands the area available for high radiation dose and is further built into the reflective cavity. The reflective cavity reflects back again, and once again uses ultraviolet reflection to enhance the radiation dose of ultraviolet light. The device is used for air disinfection and sterilization, or water disinfection and sterilization, or surface disinfection and sterilization of utensils, or food surface preservation scanning, plant breeding, photomedicine Scanning provides applications such as high-radiation agent UV curing.

UV known prior art mostly uses mercury-containing radiation sources. In addition to being environmentally friendly, the bandwidth of the light source ranges from 254nm to visible light, and the wavelength range of 250-285nm that can be used for sterilization can be used for light curing with a small proportion of 350-405nm. For specific wavelengths It is a waste of energy outside the interval. UVLED is a single band and saves electricity; very few UVLEDs are used as germicidal radiation sources, and the radiation source parts are arranged in a fixed manner, or static multi-particle array distribution, high-density layout, but poor radiation dose uniformity For example, the definition of LED radiation angle: the angle between the axis light and the 50% light attenuation is the luminous angle (see Figure 1). It can be seen that there is more than 50% of the light radiation unevenness between the middle axis light and the side. The previous technology is difficult to achieve uniform light sex.

The previous technology is unable to have a long distance and a large area with high radiation dose. For example, when a 3535 crystal UVLED has an angle of 120 degrees and is projected at a high distance of 2 cm, the area change is 5297.22mm ^{2 and the} calculation is as follows: usually a radiometer is used Take out the radiation intensity mw/cm ^{2 from the} area of 1 ² mm. 1/5297.22=0.000189=0.0189% area ratio, the angle is inversely proportional to the square of the distance area, which has a great influence on the radiant light; the prior art has a UV liquid organic glue with 350-405nm light initiator added, and then cast the corresponding wavelength UV energy, the energy is related to the distance, and the energy is related to the emission angle. Therefore, the long-distance large-area radiation dose is very low and cannot achieve second curing or photopolymerization curing. In order to achieve large-area light uniformity, light curing requires a large angle, and the angle greatly reduces the radiation efficiency. The power must be increased to help fast curing. As a result, the material will be scorched by radiant heat. The vaporized small molecules will pollute the UV lamp beads. The distance is enlarged, and the result is that the light curing is not complete and the surface is sticky.

The so-called reflective scanning method in the prior art is used in text or image capture input devices, so the device includes 1. light source 2. photoreceptor (such as photocoupler CCD) two elements, in the scanning method coordinates, X-axis and Y-axis light is required Vectors, and the Z-axis position is required to display the full picture of text or images. Most of the light sources are lasers to complete image processing, such as photocopiers or eye iris scanning. And our scanning method, only linear vector scanning of the light source, no X, Y axis position, and no Z axis position orientation, for continuous back and forth in-situ displacement scanning, the radiation beam area directly works, providing ultraviolet energy as a sterilization and inactivation, Or supply photopolymerization energy, or help vitamin D synthesis, no photoreceptor recording, no image capture input device.

In view of this, the creator has invested a lot of energy and spirit in research and development, and has continued to make breakthroughs and innovations in this field, hoping to solve the deficiencies of conventional use with novel technical means, in addition to bringing better products to the society, especially for virus elimination and Personal protection also promotes the development of the UVLED industry.

The purpose of this creation is to provide a focused beam UVLED ultraviolet scanning device. The scanning device changes the projection direction of ultraviolet rays through a rotating polygonal multi-reflective aluminum mirror. The beam area method increases the application breadth of the product. Secondly, the device uses concentrated light UVLED lamp beads to provide a high radiation dose ultraviolet lamp source, so as to extend the effective ultraviolet beam area scanning range. In addition, the integrated beam UVLED ultraviolet scanning device created by this creation can sterilize microorganisms and viruses, oxidize and deodorize organic gases, and polymerize organic liquids with light initiators, and help mushrooms to grow and synthesize vitamin D. , For the skin from phototherapy to disinfect skin lesions and so on.

UV LED ultraviolet light sterilization is currently the most ideal sterilization, disinfection, preservation, breeding, and is also the best method for UV glue light curing. According to the photochemical theorem "Grotthuss Draper's Law (Grotthuss Draper's Law, 1818)", a chemical reaction can only occur if the wavelength of the spectrum can be absorbed. The effective absorption bandwidth of the DNA and RNA peaks of germs or microorganisms is about 250-285nm, which is also the best wavelength region for sterilization. 2. The radiation dose must be greater than the effective activation energy of the substance. When the virus absorbs more than the lethal radiation dose, the bacteria can be killed or disinfected by broken bonds, such as Escherichia coli (Fecal coliform) K = lethal dose 6600μW/cm ² , Apply the formula such as K=I(intensity μW/cm ² )* t(time-sec), I is the radiation intensity of the irradiation, as long as I is high enough to kill the bacteria is feasible, when the radiation is lower than 70μW/cm ² the virus itself There will be a correction function, which is called ineffective disinfection. Therefore, the UVLED radiation wavelength range should be corresponding and the radiation intensity should be high enough, not only can efficiently and quickly sterilize and inactivate, but also be safe and free of secondary pollution. For UV glue, 350-405nm light is usually added. Starter (light absorber area), and then cast with corresponding wavelength UV radiation to help fast curing. In addition, 280-350nm is used for photomedicine and plant breeding to help vitamin D synthesis.

The reflective cavity has the disadvantages of increasing the reuse of the radiation, shortening the sterilization time, and ultraviolet sterilization. Since the light travels in a straight line, if the germs hide on the backlit surface of the dust, they will be missed. After multiple reflections, the UV light changes its direction again and again, which can avoid the omissions and eliminate the germs without hiding. This is the special effect of this method.

The radiant light is radiated from the opening to sterilize the surface of medical equipment and food. For preservation or preservation, the radiation width or area is determined by the side opening angle and length of the side open reflective cavity.

The smaller the high luminous angle, the more concentrated the light intensity, and the length can be increased according to requirements. The UVLED250-405nm lamp bead is not a laser beam, but relies on the internal reflection of the hollow metal mirror to change the direction of the radiation light and the overlap of the light to make it uniform. The diameter of the hollow metal tube restricts its light shape and homogenizes the light. It is also called beam collection. The hollow metal tube can be reprocessed into a direction perpendicular to the surface of the radiant light emitted by the crystal grain to form a continuous inner concave-convex triangular cylindrical mirror. As shown in Figure 3d, or the continuous concave-convex rectangular cylindrical mirror as shown in Figure 3e, and the continuous inner concave-convex arc-shaped aluminum reflector as shown in Figure 3c, the reflected light and the continuous cylindrical shape are perpendicular to the meridian focus line, and the radiated light focus line and the crystal grain surface Projected outward in the vertical direction to form a beam-collecting UVLED lamp bead parallel to the direction of the grain light source.

Secondly, the material of the fixing seat can be one of organic materials, inorganic materials, metal materials, etc. The body of the fixing seat has a rotating device motor and a PCB board fixing screw hole, and the fixing seat includes a plurality of fixing brackets. The PCB substrate is one of PCB (RF4 organic material), MPCB (Metal PCB), and CPCB (Ceramic PCB).

According to the technical standards of disinfection and sterilization, the radiation dose of killing germs is K=I( The radiation intensity is μW/cm ² )xt (radiation time-sec). The stronger the radiation dose, the shorter the time, and the two become inversely proportional.
