Definitions

  • 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.
  • FIG. 1 illustrates a fluorescent lamp 1a including a glass tube 10a having a fluorescent material 15a coated on an inner wall thereof, filaments 11a disposed at two ends thereof; wherein the filament 11a has a duplicate wrap or triple wrap of electrode and an electronic radiation material spread thereon.
  • the fluorescent lamp 1a has 2.33 torr of argon gas and proper capacity of quicksilver installed therein in order to discharge electricity easily.
  • the electrode (negative pole) is previously heated by an electric current, thereby to discharge a large number of thermo electrons 12a in the tube, and the thermo electrons 12a will be guided to another electrode (positive pole) thereby to start to discharge.
  • the thermo electrons 12a will collide with quicksilver electrons 13a, thereby to generate ultraviolet rays 14a (253.7 nm), and the ultraviolet rays 14a will excite the fluorescent material 15a to transform as visible light 16a.
  • the visible light 16a 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.
  • 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 2a on the glass tube 10a of the fluorescent lamp 1a, so that the yellow PE film 2a can cut off the light of under 500 nm wavelength thereby to prevent the sensitive material from generating the reaction.
  • the yellow PE film 2a will provide a protected function, i.e.
  • the glass tube 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.
  • the yellow PE film 2a will cause the color fading and to go bad, and it cannot be recycled thereby to fail to provide an environmental protection function.
  • 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.
  • 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.
  • the present invention provides a light casing structure with yellow light area of an illuminated device used to semiconductor or integrated circuit (IC) factory, wherein the illuminated device can be a fluorescent lamp 1, a fluorescent bulb 2, or a window glass 3 of a house or a car, etc.
  • the illuminated device can be a fluorescent lamp 1, a fluorescent bulb 2, or a window glass 3 of a house or a car, etc.
  • the fluorescent lamp 1 (shown as FIG. 3) includes a transparent casing (like a glass tube 10), a yellow preparation 11 uniformly sprayed on a surface of the glass tube 10 and a luminescent source 12 arranged within the glass tube 10 (or the other light source).
  • the yellow preparation 11 sprayed around the glass tube 10 will prevent ultraviolet from being diffused outwardly from an inner of the glass tube 10 for cutting off the ultraviolet of under 500 nm wavelength, thereby to only enable the light source of above 500 nm wavelength to be penetrate out.
  • the yellow preparation 11 is a kind of yellow transparent dense liquid, and the dense liquid is constituted by components and its percentage of weight, as follows: COMPONENT PERCENTAGE OF WEIGHT glycidoxypropyltrimethoxysilane (GPTMS) 28.0 ⁇ 52.0 resin (E-114) 13.0 ⁇ 19.0 isopropyl (IPA) 0.1 ⁇ 0.2 nitric acid 1.0 ⁇ 1.6 propyl alcohol zirconium 11.0 ⁇ 15.0 yellow dyestuff 1.2 ⁇ 1.6 ethyl acetate 0.2 ⁇ 0.4 sodium hydroxide 0.1 ⁇ 0.3 sodium chloride 0.01 ⁇ 0.05 Ethanol 16.0 ⁇ 22.0 methyl alcoho 0.8 ⁇ 1.1 Hardener 0.5 ⁇ 0.7 pure water 3.0 ⁇ 9.0
  • the dense liquid is constituted by the components and its preferred percentage of weight, as follows: COMPONENT PERCENTAGE OF WEIGHT glycidoxypropyltrimethoxysilane (GPTMS) 40.0 resin (E-114) 17.0 isopropyl (IPA) 0.15 nitric acid 1.3 propyl alcohol zirconium 14.0 yellow dyestuff 1.4 ethyl acetate 0.3 sodium hydroxide 0.2 sodium chloride 0.03 Ethanol 17.0 methyl alcoho 0.9 Hardener 0.6 pure water 7.1
  • the dense liquid is constituted by the components and its weight, as follows: COMPONENT PERCENTAGE OF WEIGHT glycidoxypropyltrimethoxysilane (GPTMS) 16.0 resin (E-114) 6.8 isopropyl (IPA) 0.06 nitric acid 0.52 propyl alcohol zirconium 5.6 yellow dyestuff 0.56 ethyl acetate 0.12 sodium hydroxide 0.08 sodium chloride 0.01 Ethanol 6.8 methyl alcoho 0.36 Hardener 0.24 pure water 2.85
  • the fluorescent bulb 2 (shown as FIG. 4) includes a glass tube 20 and a yellow preparation 21 uniformly sprayed on an inner or an outer surface of the glass tube 20, and the fluorescent bulb 2 has an exterior shape different from the glass tube 10 of the fluorescent lamp 1.
  • the window glass 3 (shown as FIG. 5) includes a glass plane 30 and a yellow preparation 31 uniformly sprayed on an inner or an outer surface of the glass plane 30, and the window glass 3 can installed the window of the house or car for preventing the ultraviolet from being illuminated from the sun.
  • FIG. 6 is a flow diagram illustrating a manufacture method of the light casing structure with yellow light area due to the present invention
  • the manufacture method includes the steps of:
  • FIG. 7 is a flow diagram illustrating a manufacture method of another embodiment due to the present invention, the manufacture method includes the steps of:
