The first plug 4 is installed at one end of the housing 1, and the second plug 5 is installed at the other end, so that both ends of the housing 1 can be effectively closed by the design, light leakage or external dust entering can be prevented, and thus, internal components can be protected. The lamp plate 6 is arranged in the shell 1, and the ultraviolet LED light source 7 is arranged on the lamp plate 6. The ultraviolet LED light source 7 is powered by a circuit board and needs a low-voltage direct current power supply for power supply. The serial connection mode of the ultraviolet LED lamp beads can ensure that the circuit form is simple and the working state is stable. The secondary optical column 2 is arranged in the light path direction of the ultraviolet LED light source 7, and is used for converting ultraviolet rays emitted by the ultraviolet LED light source 7 into required parallel light in the horizontal direction through twice refraction, and the parallel half angle is smaller than 2.5 degrees. The power line and the connector 3 are electrically connected with the lamp panel 6 through the first plug 4, so that the power can be safely and effectively transmitted to the lamp panel 6 and the ultraviolet LED light source 7.
Further, as shown in fig. 2, the casing 1 is made of metal, preferably aluminum alloy, for fixing and protecting the internal structure. The casing 1 has a groove structure for mounting and fixing the lamp panel 6 and the secondary optical column 2, and has a first screw fixing hole 102 for mounting the plug. In order to promote better heat dissipation of the lamp panel 6 and the ultraviolet LED light source 7, the shell 1 is also provided with a heat dissipation fin 101 structure. The color inside the housing 1 is preferably black for absorbing stray light.
Further, the optical column 2 has a semi-cylindrical shape in shape. The secondary optical column 2 may be a plurality of splices in consideration of product cost and processing and installation. The secondary optical column 2 is inserted into the groove structure of the housing 1 through the side of the housing 1.
Further, as shown in fig. 6, the first plug 4 is made of plastic, and is fixed on the housing 1 through a screw fixing hole 401, and a human body sensing area 402 is arranged right in front of the first plug 4, and a human body sensing module 403 is contained in the human body sensing area 402. The human body sensing module 403 is used for sensing whether personnel exist in the area above 2.1m right in front of the product, if the personnel exist, the human body sensing module 403 can cut off the power supply of the ultraviolet LED light source 7 immediately, so that the personnel can be prevented from being burned by ultraviolet rays. The human body sensing module 403 may adopt an infrared pyroelectric human body sensing or microwave radar human body sensing technology, preferably a microwave radar human body sensing technology. If the infrared pyroelectric human body sensing technology is used, the human body sensing area 402 needs to be perforated to expose the human body sensing module 403.

Further, the lamp panel 6 is an aluminum substrate or a copper substrate for mounting the ultraviolet LED light source 7. The lamp panel 6 is inserted into the groove structure of the housing 1 through the side of the housing 1. The ultraviolet LED light source 7 is a third-generation semiconductor cold light source and is arranged on the lamp panel 6. The packaging material of the ultraviolet LED light source 7 is a quartz or sapphire packaging lens 701, and the packaging lens 701 is semi-ellipsoidal. Preferably, the peak wavelength range of ultraviolet rays emitted by the ultraviolet LED light source 7 is 230 nm-290 nm, and the light emitting angle of the ultraviolet LED light source 7 is 10-60 degrees. The ultraviolet LED light source 7 emits ultraviolet rays, the light rays are converted into required parallel light in the horizontal direction by the secondary optical column 2 through twice refraction, and the parallel half angle is smaller than 2.5 degrees, so that the ultraviolet rays are horizontally emitted from the front surface of the sterilizer parallel to the ground.
Further, it is preferable that the diameter of the secondary optical column 2 is 15 mm-50 mm, and the distance between the secondary optical column 2 and the ultraviolet LED light source 7 is 10 mm-50 mm.
The working principle of the utility model is as follows:
As shown in fig. 3, when the cross section perpendicular to the upper layer flat jet ultraviolet air sterilizer of the present utility model is analyzed and the inverse convergence point of the outgoing light of the ultraviolet LED light source 7 is coincident with the focal point F of the secondary optical column 2, the light emitted from the up and down direction of the ultraviolet LED light source 7 is converted into parallel light by the secondary optical column 2, and the ultraviolet light is emitted horizontally from the front of the sterilizer parallel to the ground so that the ultraviolet light does not irradiate the lower layer space, thereby realizing the function of the upper layer flat jet ultraviolet air sterilizer. At the same time, the light is further optimized by absorbing the relevant stray light inside the housing 1.
Let the radius of the secondary optical column 2 be R, the refractive index of the secondary optical column 2 to the ultraviolet rays emitted by the ultraviolet LED light source 7 be n, the ultraviolet LED light source 7 be a surface light source, the light emitting angle of the ultraviolet LED light source 7 be α, and the diameter of the light emitting surface be D.
The focal length f of the secondary optical column 2 under the section can be obtained by the focal length of the plano-convex lens
f=R/(n-1)
The distance d between the light emitting surface of the ultraviolet LED light source 7 and the secondary optical column 2 can be calculated by the law of trigonometry and light refraction
d=f-D/(2*tan(α/2))-(n-1)*f/n
As shown in fig. 5, analysis is performed from a cross section perpendicular to the ground and forming an angle beta with the upper level jet ultraviolet air sterilizer of the present utility model, and under this cross section plane, the cross section of the secondary optical column 2 is elliptical, and it can be calculated that the elliptical long half axis is R/cos β, the short half axis is R, and the distance between the reverse convergence point of the emitted light of the ultraviolet LED light source 7 and the secondary optical column 2 is f/cos β.
By calculating the focal length of the lens, the focal length f1 under the section of the beta angle can be obtained
f1≈R/cosβ(n-1) =f/cosβ
The light-emitting light reverse converging point of the ultraviolet LED light source 7 is just at the focus under the section of fig. 5, so the light emitted from the ultraviolet LED light source 7 in the up-down direction under any section can be converted into parallel light with the ground direction after passing through the secondary optical column 2.
The preferred embodiments of the present utility model have been described in detail, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present utility model, and the various changes are included in the scope of the present utility model.
