Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Fig. 1 and Fig. 2 are please referred to, the utility model provides a kind of curved compound eye lens type deep ultraviolet disinfection lighting device, packet
Include: rectangle installs top plate 1, the two inclination flanks 2 in described installation 1 liang of long side of top plate, set on described 1 liang of installation top plate short
Two end plates (not shown) on side, set on installation 1 lower surface of top plate several deep ultraviolet LED light sources 3, be set to it is described dark purple
The curved compound eye lens subassembly 4 of outer 3 lower section of LED light source.Reflecting layer 5 is equipped on the inside of two flanks 2, the reflecting layer 5 can
The light that the deep ultraviolet LED light source 3 is irradiated on the flank 2 is reflected on the curved compound eye lens subassembly, is improved
Light source utilization rate.Several deep ultraviolet LED light sources 3 spaced set on the length direction of the installation top plate 1.It will be deep
Ultraviolet LED light source is combined with curved compound eye lens, light can be carried out deviation homogenizing, the light for issuing LED light is more equal
It is even, without hot spot；Light irradiated area after diverging homogenizing is big, can carry out disinfection for bigger area, improve disinfection efficiency.
Fig. 1 and Fig. 4 are please referred to, the curved compound eye lens subassembly 4 includes: support plate 41, microlens array 42, Yi Jishe
Optical adhesive 43 between the support plate 41 and the microlens array 42, the microlens array 42 is by several hemisphere
Shape lenticule is arranged in array, and the microlens array 42 includes incidence surface 421 and light-emitting surface 422, assembled disinfection
Incidence surface 421 described in lighting device is spherical surface, and the light-emitting surface 422 is hemispherical curved surface and arc-shaped curved surface interval setting group
At.The material of the microlens array 42 is dimethyl silicone polymer, and the microlens array 42 is integrated by mold casting forming
Formula structure.Dimethyl silicone polymer (PDMS) is the stable silicone elastomer of physical and chemical properties, and optical clarity is very high,
When there is deformation, significant changes can occur for its refractive index；In addition the contour accuracy of PDMS is up to 10nm hereinafter, because wide
It is general to be applied to nanometer technique field.For PDMS micro-structured form generally using molding, specific forming process includes: the first step,
