The reflection shield of UV lamp
Technical field
The present invention relates to a kind of air channel of UV lamp.
Background technology
In air brushing and print field, the UV lamp has obtained general application at present, and the UV of liquid state seal China ink is coated onto the surface of the work of curable materials or stock, can realize sclerosis through the light irradiation of UV lamp.In order to realize that the light that the UV lamp is sent can shine on the surface of the work as much as possible, on the UV lamp, be provided with reflection shield, reflection shield can reflex to the UV light irradiation on the surface of the work to the light on it.The reflection shield of prior art generally have be positioned at about the arc surface of two 1/4 π constitute, the axial line of each arc surface be positioned at the UV lamp center line under, as shown in Figure 1, this two-part cover body in diffuser left and right sides all has only one section arc reflective surface 1, and fluorescent tube is in the reflection kernel point, intercepted the transmission of part energy, and the UV lamp is thick more, the light that stops is many more.Therefore, might cause the part surface of the work of stock to can not get enough light source irradiations in this case, it is not up to standard part surface of position adhesive force to occur, causes the unstable product quality problem.
Summary of the invention
The reflection shield that the purpose of this invention is to provide the better UV lamp of a kind of reflecting effect.
The technical solution used in the present invention is: a kind of reflection shield of UV lamp, comprise left side cover body and right side cover body, have first arc surface and second arc surface on the inner surface of described left side cover body, described first arc surface and second arc surface constitute the reflecting surface on the cover body of described left side, the axial line of described first arc surface is positioned at the lower right side of the center line of UV lamp, the axial line of described second arc surface also is positioned at the lower right side of the center line of UV lamp, the axial line of described first arc surface refers to the connecting line in the center of circle of each vertical circular cross-section on first arc surface, and the axial line of described second arc surface refers to the connecting line in the center of circle of each vertical circular cross-section on second arc surface; Have three-arc face and the 4th arc surface on the inner surface of described right side cover body, described three-arc face and described first arc surface are the line of symmetry symmetry with the center line of UV lamp, and described the 4th arc surface and described second arc surface are the line of symmetry symmetry with the center line of UV lamp also.
Preferably, the radian of described first arc surface is 27~32 degree, and the radian of described second arc surface is 5~12 degree.
Preferably, the axial line of described first arc surface is positioned at the lower right side of the axial line of described second arc surface.
Preferably, have a plurality of radiating fins respectively on the outer surface of described left side cover body and right side cover body.
Preferably, the material of this reflection shield is an aluminium.
By implementing above technical scheme, the present invention obtains following progress: use this reflection shield, owing on the cover body of the left and right sides two sections arc surfaces that stagger mutually with UV lamp center line are arranged all, like this, the UV light irradiation to the reflection shield after, most reflection rays UV lamp that will stagger shines from its sidepiece, that is to say improvement after, reflection efficiency improves, and most of energy that the UV lamp sends also can both pass to workpiece.Therefore, use this reflection shield can avoid the bearing plane local location of workpiece to can not get the phenomenon that efficient light sources shines, thereby guaranteed the quality of processing work because of being intercepted by the UV lamp.

The specific embodiment
Further set forth concrete structure of the present invention below in conjunction with accompanying drawing.
Shown in accompanying drawing 2, a kind of reflection shield of UV lamp, comprise left side cover body 3 and right side cover body 4, have first arc surface 31 and second arc surface 32 on the inner surface of described left side cover body 3, the reflecting surface that described first arc surface 31 and second arc surface 32 constitute on the described left side cover body 3, the axial line of described first arc surface 31 is positioned at the lower right side of the center line of UV lamp 2, the axial line of described second arc surface 31 also is positioned at the lower right side of the center line of UV lamp 2, the axial line of described first arc surface 31 refers to the connecting line in the center of circle of each vertical circular cross-section on first arc surface 31, and the axial line of described second arc surface 32 refers to the connecting line in the center of circle of each vertical circular cross-section on second arc surface 32; Have three-arc face 41 and the 4th arc surface 42 on the inner surface of described right side cover body 4, described three-arc face 41 and described first arc surface 31 are the line of symmetry symmetry with the center line of UV lamp 2, and described the 4th arc surface 42 is the line of symmetry symmetry with the center line of UV lamp 2 also with described second arc surface 32.
In the present embodiment, the radian of described first arc surface is 27~32 degree, and the radian of described second arc surface is 5~12 degree, and the axial line of described first arc surface is positioned at the lower right side of the axial line of described second arc surface.In addition, have a plurality of radiating fins 5 on the outer surface of described left side cover body and right side cover body respectively, the material of this reflection shield is generally selected aluminium for use.
As shown in Figure 2, use this reflection shield, owing on the cover body of the left and right sides two sections arc surfaces that stagger mutually with UV lamp center line are arranged all, like this, the UV light irradiation to the reflection shield after, most reflection rays UV lamp that will stagger shines from its sidepiece, reflection efficiency improves, most of energy that the UV lamp sends also can both pass to workpiece, thereby has guaranteed the quality of processing work.
The foregoing description only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that spirit essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
