Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1, the light-gathering structure of the germicidal lamp includes a germicidal lamp 10 and a transparent lampshade 20 covering the germicidal lamp 10, and is characterized in that: the LED lamp further comprises a light-gathering lamp shade 30 with a light outlet hole 31 and a mounting hole 32, wherein the inner wall surface of the light-gathering lamp shade 30 is a conical arc-shaped surface 33, and a smooth reflecting layer 34 is arranged on the conical arc-shaped surface 33; the germicidal lamp 10 and the transparent lampshade 20 extend into the light-gathering lampshade 30 from the mounting hole 32, and the light-emitting part 11 of the germicidal lamp 10 is positioned on the central axis of the conical arc-shaped surface 33; the light parallel to the central axis of the conical arc-shaped surface 33 irradiates any point on the reflecting layer 34, and the reflected light can pass through the light-emitting part 11 of the germicidal lamp 10.

As shown in fig. 1 and fig. 2, the germicidal lamp light-gathering structure can reflect the germicidal light 40 emitted by the germicidal lamp 10 through the reflective layer 34 as emergent light parallel to the central axis of the conical arc-shaped surface 33 and then emit the emergent light from the light-emitting hole 31, so as to exert the germicidal effect of the germicidal lamp 10 to the maximum and reduce the photo-aging effect of the germicidal lamp 10 on other surrounding components.

Wherein, the germicidal lamp 10 can emit ultraviolet rays and other sterilizing rays 40 to sterilize; the germicidal lamp 10 may be of various types, preferably a UVC-LED lamp. UV refers to ultraviolet rays, UVC is a C wave band in the ultraviolet rays, the wavelength is between 100 and 280nm, but the wavelength below 200nm is vacuum ultraviolet rays and can be absorbed by air; therefore, UVC generally refers to the portion of the ultraviolet C band that can pass through the large air, and the wavelength is between 200nm and 280 nm. Among all ultraviolet rays, UVC with the wavelength of 260-280 nm has the strongest sterilizing effect. LED refers to the way UVC is emitted, for example: conventional ultraviolet lamps have been using mercury lamps to emit light. The UVC-LED lamp is selected as the bactericidal lamp, so that broad-spectrum and efficient bactericidal effects can be achieved, the appearance size is small, the influence on the air inlet quantity of an air conditioner is small, secondary pollution cannot be generated, and the cost performance is high; in addition, the UVC-LED lamp also has the advantages of being fast in starting, multiple in allowed switching times, capable of being powered by a battery and the like.

The transparent lampshade 20 is mainly used for covering the germicidal lamp 10 and plays a role in protection and dust prevention; meanwhile, the sterilizing radiation 40 emitted by the sterilizing lamp 10 can be ensured to be scattered, and the part needing sterilization and disinfection is irradiated. The structure of the transparent lampshade 20 can be various, and is preferably a hemispherical structure; the transparent lamp cover 20 is made of a transparent material, preferably sapphire; the transparent lampshade 20 made of sapphire has a better heat dissipation effect, and can improve the working efficiency and prolong the service life of the germicidal lamp 10.

The condenser lamp cover 30 is mainly used for collecting the scattered sterilizing rays 40 so as to intensively irradiate the parts needing sterilization and disinfection, improve the sterilizing effect and avoid the accelerated aging process of surrounding parts due to the scattered irradiation of the sterilizing rays 40. The light outlet 31 is mainly used for emitting the reflected killing rays 40, and is one end of the condensing lampshade 30 with a larger inner diameter; the mounting hole 32 is mainly used for the germicidal lamp 10 and the transparent lampshade 20 to penetrate into the light-focusing lampshade 30, and is the end of the light-focusing lampshade 30 with the smaller inner diameter.

The conical arc-shaped surface 33 is a light-gathering structure of the light-gathering lamp cover 30, and is mainly used for reflecting the divergent killing rays 40 towards one direction together with the reflecting layer 34 so as to converge the scattered killing rays; the conical arc surface 33 generally needs to be designed and formed according to the installation position of the germicidal lamp 10 in the light-focusing lampshade 30, so as to ensure that light parallel to the central axis of the conical arc surface 33 irradiates any point on the reflective layer 34, and the reflected light can pass through the light-emitting part 11 of the germicidal lamp 10. The light-reflecting layer 34 is mainly used for reflecting the sterilizing radiation 40, and can be various, and is preferably a nano titanium oxide layer or a rhodium film layer. The rhodium film layer has a very good reflection effect on ultraviolet light, and when the germicidal lamp 10 is an ultraviolet lamp, the reflective layer 34 is a rhodium film layer.

Referring to fig. 2, the design process of the conical arc surface 33 and the reflective layer 34 is as follows:

firstly, a point of the killing light ray 40 which irradiates the reflective layer 34 is determined, the reflected light of the killing light ray 40 needs to be emitted from the light emitting hole 31 and is parallel to the central axis of the conical arc-shaped surface 33, so that the incident path and the reflected path of the killing light ray 40 are determined, because the incident angle α 1 is equal to the reflected angle β 1, namely α 1 is equal to β 1, the normal P1 can be determined, and according to the relation that the tangent line is parallel to the normal, the point tangent line N1 of the killing light ray 40 which irradiates the reflective layer 34 can be determined, and the curvature of the irradiated point can be determined;

similarly, another point of the other killing light ray 40 irradiated on the reflective layer 34 is determined, and the corresponding incident angle α 2, reflection angle β 2, normal P2, tangent N2 and curvature can be obtained;

finally, by analogy, the killing light rays 40 are continuously increased and concentrated to n, and the corresponding incident angle alpha n, reflection angle beta n, normal Pn, tangent Nn and curvature can be obtained; the plurality of tangent lines Nn can be fitted in the light-gathering lamp cover 30 to form a conical arc surface 33, and a corresponding smooth reflecting layer 34 is arranged.
