Abstract
The utility model relates to a cold cathode fluorescent lamp without mercury which makes use of ultraviolet generated by cathode luminescence to excite fluorescence powder to send out visible light without mercury. The cold cathode fluorescent lamp without mercury does not cause the mercury pollution of the environment, and can be instantly actuated. The brightness of the utility model with long life time is free from the effect of the environmental temperature.
Description
One, technical field
The utility model relates to a kind of cold-cathode fluorescence lamp, relates in particular to mercury-free cold cathode fluorescent lamp not mercurous in a kind of fluorescent tube.
Two, background technology
Energy-conservation and life-span longly just is applied to illumination by increasingly extensive to cold-cathode fluorescence lamp because of it, and all contain mercury in original cold-cathode fluorescence lamp and the hot-cathode fluorescent lamp, the combustion back mercury atom that uses as a lamp is excited, and the ultraviolet ray excited fluorescent material that is coated on the lamp wall that the mercury atom that excites sends produces visible light.But after fluorescent lamp damaged, the mercury in the lamp can produce severe contamination to environment.The brightness that contains hg fluorescent lamp is influenced by the interior mercury vapor pressure of lamp, so it starts slowly, the brightness of lamp is influenced by ambient temperature, and the consumption of mercury influences the lamp life-span in the lamp.
Three, summary of the invention
The utility model aims to provide and does not a kind ofly use mercury, and the ultraviolet ray excited fluorescent material that is coated on the lamp wall that utilizes gas discharge to produce produces the mercury-free cold cathode fluorescent lamp with high light photoelectric transformation efficiency of visible light.
In conjunction with embodiment of the present utility model, existing that the utility model content introduction is as follows:
1, the utility model by glass shell (1), phosphor powder layer (2), the lamp chamber (3) of containing the mist of nitrogen or nitrogen and inert gas, electrode (4) (4a), stem stem (5), ballast (6), lamp holder (7) etc. form, and it is characterized in that having the lamp chamber (3) of the mist that contains nitrogen or nitrogen and inert gas.
After the utility model energized, by placing restrictions on electric current at the built-in ballast (6) of lamp holder (7), glow discharge takes place between (4a) in the electrode (4) that is fixed on the stem stem (5), because of the gas in the lamp chamber (3) of the mist that contains nitrogen or nitrogen and inert gas is the gaseous mixture of nitrogen or nitrogen and inert gas, electrode (4) (4a) the negative brightness of negative electrode on surface give off the ultraviolet ray of strong 310nm-400nm, ultraviolet ray excited be coated in the phosphor powder layer (2) that glass shell (1) inner surface and excitation wavelength meet 310nm-400nm and make it send visible light.Energy loss when reducing discharge, electrode (4) in order to improve luminous efficiency (4a) can select the low metal material of work function or on metal coated electronics powder.
Because the utility model has adopted gas discharge to produce ultraviolet ray excited fluorescent material and has sent visible light and do not use mercury, overcome the pollution of mercury to environment.Mercury-free cold cathode fluorescent lamp is not influenced by mercury vapor pressure can moment to start, and brightness is not influenced by ambient temperature, and the life-span is long.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model:
(1) is glass shell among the figure, and (2) are phosphor powder layer, and (3) are the lamp chamber of containing the mist of nitrogen or nitrogen and inert gas, and (4) are electrode (4a), and (5) are stem stem, and (6) are ballast, and (7) are lamp holder.
Fig. 2 is other shell shape schematic diagram of the present utility model.
Fig. 3 is other electrode shape schematic diagram of the present utility model:
(a) is the plate-shaped electrode schematic diagram of Fig. 1 among the figure, (b) is the dome electrode schematic diagram, (c) is spiral rod-shaped electrode schematic diagram, and electrode also can be netted or other shape.
Claims (1)
1, a kind of mercury-free cold cathode fluorescent lamp, by glass shell (1), phosphor powder layer (2), electrode (4) (4a), stem stem (5), ballast (6), lamp holder (7) form successively, it is characterized in that: the lamp chamber (3) that the mist that contains nitrogen or nitrogen and inert gas is arranged.
