BACKGROUND OF THE INVENTION
(1). Field of The Invention
[0001] 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.
(2). Description of the Related Art
[0002] Please refer to FIG. 1, which 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. However,
the fluorescent lamp 1a 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 1a, 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 12a in the tube, and the thermo electrons 12a will
be guided to another electrode (positive pole) thereby to start to discharge. However,
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.
[0003] Additionally, shown as FIG. 2, 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. 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 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. Another, the yellow PE film 2a 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 2a 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
[0004] 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.
[0005] 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.
