Abstract
An energy-efficient cold cathode glow tube, belongs to the gas discharge light display device field, which is consisted of a glass casing, an electrode and a lead-out wire. The glass casing is made of lead glass or lead-free high-barium low-sodium glass; the electrode is nickel plated iron wire coated by electronic powder; the electrode is connected with the lead-out wire by dumet wire; inert gas is filled in the glass casing; the lamp filled with neon or neon/argon can emits tamgerine visible light, while the glow tube filled with mixed inert gases containing argon, xenon, helium and neon with different fluorescent powder coated on the inner wall of the glass casing, can emit green, blue, whit and yellow visible light. The utility model is a light display device adopting the discharging of cold cathode gas glow tube; achieves the advantages of simple and reasonable structure, easy manufacturing, low cost, low ignition voltage, low working current, low electricity consumption and long life; can emit red, green, blue, whit and yellow visible light; can be widely used as display and illumination light source; and has excellent popularization value and market prospect.
Description
Technical field
The utility model relate to a kind of power consumption less, the glow discharge tube of cold cathode, belong to the gas discharge light display device.
Background technology
The light that the lamp of existing illumination indication usefulness is generally when utilizing tungsten filament incandescent luminous is used as the illumination indication.Also utilize fluorescent material ultraviolet ray excited luminous down, existing glow discharge tube, its negative electrode are hot cathode, and after the heating of target filament, lamp produces discharge and launches ultraviolet ray, and excitated fluorescent powder is luminous.This two classes lamp operating current is bigger, and power will be between several watts to tens of watts.
The utility model content
The purpose of this utility model is at existing glow discharge tube above shortcomings, provides a kind of target that do not need to heat, and few energy-saving cold-cathode glow discharge valve consumes energy.
The purpose of this utility model is to realize by the improvement to existing glow discharge tube: energy-saving cold-cathode glow discharge valve, the electrode, blanketing gas and the electrode that comprise glass bulb and be arranged in the glass bulb are drawn lead, it is characterized in that described electrode is nickel coated iron wire or nickel wire or nickel alloy wire, scribble the electronics powder on the electrode, the closure part of glass bulb is in the glass bulb bottom, and exhaust sealing-in point is at the top of glass bulb.
Described closure part is flat-shaped, and width is less than the diameter of glass bulb.
Described blanketing gas is a neon or neon is argon-mixed or the mixed inert gas of argon and xenon, helium, neon.
The material of described glass bulb is the low sodium crown glass of lead glass or high barium, and the glass bulb inwall scribbles fluorescent material.Fluorescent material is multicolour fluorescent material.
The utility model is rational in infrastructure simple, manufactures easily, and the visible light that utilizes gas to produce in glow discharge, or the ultraviolet ray that produces comes excitated fluorescent powder luminous, can send visible lights such as green, blueness, white, yellow when glow discharge.This glow discharge tube is the oxide cold cathode, do not need target to heat, when carrying out glow discharge, its starting voltage is less than AC90V, operating current is very little, generally between 0.3mA～3mA, the power consumptive province, every lamp power is about 1/4W, maximum is no more than 1/2W, what show photochromicly has redness, green, blueness, white, a yellow etc., bright in luster eye-catching, only is connected in series a current-limiting resistance during use to get final product, easy to use, life-span is long, and low price is a kind of cheap and good-quality light demonstration light source.
