Abstract
The utility model discloses a kind of cold cathode discharge tube sending sodium yellow, the gas filler comprising shell, electrode and be located in shell, described inner wall of tube shell scribbles phosphor powder layer; Electrode is provided with electronic powder; Described phosphor powder layer is silicic acid zinc layers; Described gas filler is neon.The cold cathode discharge tube sending sodium yellow of the present utility model; employing neon is blanketing gas; adopt the low zinc silicate of cost as fluorescent material; the green glow color overlaid utilizing the ruddiness of neon and silicic acid zinc green powder to send obtains sodium yellow; avoid and use harmful substance mercury; completely eliminate mercury evil, be conducive to health and environmental protection.Simplify Making programme, saved cost of manufacture, design ingenious, adapt to suitability for industrialized production, the sodium yellow sent can meet the multi-field user demand such as advertisement, publicity, decoration.
Description
Technical field
The utility model relates to discharge tube technical field, is specifically related to a kind of cold cathode discharge tube sending sodium yellow.
Background technology
The existing cold cathode discharge tube sending sodium yellow is mostly made up of shell and the electrode be located in shell, in shell, be filled with argon and mercury, the ultraviolet utilizing argon and mercury to produce when gas discharge sends sodium yellow to excite the mixed fluorescent powder of the green powder of three primary colors and rouge and powder; This product is widely used in electric equipment, instrument and meter and household electrical appliance.But owing to injecting mercury in discharge tube, harm is existed to health and environment, and making is comparatively complicated, cost is higher.
Utility model content
Goal of the invention: for the deficiencies in the prior art, the utility model proposes a kind of cold cathode discharge tube sending sodium yellow, avoids using harmful substance mercury, completely eliminates mercury evil, saves cost of manufacture, meet user demand.
Technical scheme: in order to realize foregoing invention object, the technical solution adopted in the utility model is:
Send a cold cathode discharge tube for sodium yellow, the gas filler comprising shell, electrode and be located in shell, described inner wall of tube shell scribbles phosphor powder layer; Electrode is provided with electronic powder; Described phosphor powder layer is silicic acid zinc layers; Described gas filler is neon.
Described shell is leaded or high sodium crown glass shell.
Described electrode is pure nickel wire or nickel coated iron wire electrode.
Described electronic powder is brium carbonate, calcium carbonate, strontium carbonate mixing eutectic electronic powder.
Beneficial effect: compared with prior art; the cold cathode discharge tube sending sodium yellow of the present utility model; employing neon is blanketing gas; adopt the low zinc silicate of cost as fluorescent material; the green glow color overlaid utilizing the ruddiness of neon and silicic acid zinc green powder to send obtains sodium yellow; avoid and use harmful substance mercury, completely eliminate mercury evil, be conducive to health and environmental protection.Simplify Making programme, saved cost of manufacture, design ingenious, adapt to suitability for industrialized production, the sodium yellow sent can meet the multi-field user demand such as advertisement, publicity, decoration.There is good economic benefit, good social benefit can be produced.
Accompanying drawing explanation
Fig. 1 is the structural representation of the cold cathode discharge tube sending sodium yellow.
Embodiment
Below in conjunction with specific embodiment, the utility model is further described.
As shown in Figure 1, this sends the cold cathode discharge tube of sodium yellow, the gas filler comprising shell 1, electrode 2 and be located in shell, and shell 1 inwall scribbles fluorescent material 3.Utilize discharge tube two electrifying electrodes, electronic powder on electrode sends electronics due to high temperature, in electronic impact discharge tube institute's neon filling generation ionization phenomena produce ruddiness, the green glow that the ruddiness of neon and silicic acid zinc green powder send due to color overlaid just can obtain needs sodium yellow.
Wherein, shell 1 is made up of leaded or high sodium crown glass.Electrode 2 material is pure nickel wire or nickel coated iron wire, scribbles brium carbonate, calcium carbonate, strontium carbonate mixing eutectic electronic powder on its surface.Phosphor powder layer 3 is silicic acid zinc layers (zinc silicate cost will far below the mixed powder of conventional three primary colors rouge and powder and green powder).Gas filler is neon.
The utility model adopts neon to be blanketing gas; adopt the low zinc silicate of cost as fluorescent material, the green glow color overlaid utilizing the ruddiness of neon and silicic acid zinc green powder to send obtains sodium yellow, avoids and uses harmful substance mercury; completely eliminate mercury evil, be conducive to health and environmental protection.Simplify Making programme, saved cost of manufacture, design ingenious, adapt to suitability for industrialized production, the sodium yellow sent can meet the multi-field user demand such as advertisement, publicity, decoration.There is good economic benefit, good social benefit can be produced.
