Description:
BACKGROUND OF THE INVENTION  
         [0001]    (1). Field of The Invention  
           [0002]    The present invention relates to an illuminated device, and in particularly to an illuminated device having a light casing structure with yellow light area for semiconductor or integrated circuit factory.  
           [0003]    (2). Description of the Related Art  
           [0004]    Please refer to FIG. 1, which illustrates a fluorescent lamp la including a glass tube  10   a  having a fluorescent material  15   a  coated on an inner wall thereof, filaments  11   a  disposed at two ends thereof wherein the filament  11   a  has a duplicate wrap or triple wrap of electrode and an electronic radiation material spread thereon. However, the fluorescent lamp, la has 2.33 torr of argon gas and proper capacity of quicksilver installed therein in order to discharge electricity easily. Furthermore, in the action principle due to the fluorescent lamp  1   a , i.e. when it is switched, the electrode (negative pole) is previously heated by an electric current, thereby to discharge a large number of thermo electrons  12   a  in the tube, and the thermo electrons  12   a  will be guided to another electrode (positive pole) thereby to start to discharge. However, the thermo electrons  12   a  will collide with quicksilver electrons  13   a , thereby to generate ultraviolet rays  14   a  (253.7 nm), and the ultraviolet rays  14   a  will excite the fluorescent material  15   a  to transform as visible light  16   a.    
           [0005]    Additionally, shown as FIG. 2, the visible light  16   a  has a wavelength scope at 380 nm˜760 nm (wherein the yellow light has a wavelength scope at 500 nm˜580 nm), and the ultraviolet has a wavelength scope at under 380 nm. However, the ultraviolet will cause the sensitive material in semiconductor field to generate the reaction, hence the illuminated equipment used in semiconductor or integrated circuit factory with the sensitive material, it will provide a layer yellow PE film  2   a  on the glass tube  10   a  of the fluorescent lamp  1   a , so that the yellow PE film  2   a  can cut off the light of under 500 nm wavelength thereby to prevent the sensitive material from generating the reaction. Another, the yellow PE film  2   a  will provide a protected function, i.e. when the glass tube is broke in the accident, the glass fragment and the fluorescence powder will not be scattered everywhere and pollute the environment. However, the yellow PE film  2   a  will cause the color fading and to go bad, and it cannot be recycled thereby to fail to provide an environmental protection function.  
         SUMMARY OF THE INVENTION  
         [0006]    The primary purpose of the present invention is to provide a light casing structure with yellow light area and its manufacture method which uses a yellow preparation made of an organic polymer to spray on an inner or an outer surface of a glass tube for obtaining an uniform yellow area, thereby to absorb light source of under 500 nm wavelength, so that it can completely cut off the ultraviolet, and it also has some effects, as the environmental protection, the power saving, and the mosquito and bug repelling.  
           [0007]    In accordance with one aspect of the present invention, to provide a light casing structure with yellow light area and its manufacture method, wherein the light casing structure includes a transparent casing and a yellow preparation uniformly sprayed on an inner or an outer surface of the transparent casing. Furthermore, the manufacture method of the light casing structure includes the steps of: blending a dense liquid according to constituents of a yellow preparation, and placing the dense liquid into a sprayed device; placing a transparent casing of the light casing structure on a sprayed space, spraying the dense liquid on a surface of the transparent casing through a nozzle of the sprayed device, and placing the transparent casing in an oven for baking the dense liquid to harden.
