Description
Technical field
The utility model relates to a kind of electricity-saving lamp, particularly relates to a kind of ceramic electrode electricity-saving lamp.
Background technology
Electricity-saving lamp is a kind of by gas discharge, utilizes the illuminating product of light-emitting phosphor.CFL lighting, with respect to incandescent lighting, can be saved electric energy 80% left and right, and average life span extends 8 times, thermal radiation only 20%.Therefore, be widely used in now domestic lighting and commercial lighting.Along with the development of technology, electricity-saving lamp is progressively to miniaturization, long-life future development, but mostly traditional electricity-saving lamp is to excite mercury atom transmitting ultraviolet ray by filament emission electronic powder, and then excitated fluorescent powder transmitting visible ray, such design easily consumes because filament exists sputter and electronic powder, therefore the life-span of electricity-saving lamp is limited.
In view of this, the inventor, through research, develops a kind of ceramic electrode electricity-saving lamp, and this case produces thus.
Utility model content
The purpose of this utility model is to provide a kind of ceramic electrode electricity-saving lamp, can increase substantially the useful life of electricity-saving lamp, and cost is low.
To achieve these goals, solution of the present utility model is:
A kind of ceramic electrode electricity-saving lamp, comprise lamp holder, the connector of electric ballast is housed, and the fluorescent tube being connected with lamp holder by connector, described fluorescent tube comprises that inwall scribbles the tube cell of fluorescent material, is arranged on the ceramic electrode at tube cell two ends, and is placed on the amalgam in tube cell.
Above-mentioned ceramic electrode be one by 50～60% high-purity a-Al2O3 polycrystal alumina powders, the tubular earthenware that 30～40% nano Mo powders and 5～10% tungsten powder high-temperature firings form, on the inwall at ceramic electrode two ends, be respectively equipped with a concave step, two ports of tube cell are arranged on respectively in the concave step of ceramic electrode one end, blast pipe is arranged in the concave step of the ceramic electrode other end, and is tightly connected by inorganic adhesive.
On the outer surface of above-mentioned ceramic electrode, be further coated with one deck conductive silver paste thin layer, be connected with electric ballast by wire.
As preferably, above-mentioned tube cell in being, be filled with inert body helix tube or U-shaped pipe, caliber is 7.2-12mm, belongs to slim pipe diameter fluorescent tube.
Because ceramic electrode material has high dielectric constant, can form strong electric field.Because electric field strength and polarizability are linear direct ratio, when electric field is stronger, polarizability is just better, therefore ceramic electrode is also very strong to the polarizability of fluorescent tube.In the time that ceramic electrode electricity-saving lamp switches on power, first applied the electric energy of high-frequency and high-voltage by electric ballast, its can in ceramic electrode, produce by capacity effect powerful electric field, and and then polarization tube cell in inert gas and mercury atom, become plasma state.Plasma is under electric field constantly acts on, can make mercury atom excite or ionize, the same with conventional fluorescent operation principle, it can mainly produce 253.7nm ultraviolet ray, this ultraviolet irradiation, to the triphosphor Fluorescent Powder of glass-tube coated inner wall, just can transform out people's required visible ray that throws light on.
Ceramic electrode electricity-saving lamp described in the utility model utilizes capacity effect and high voltage electric field principle, to excite inner inert gas and mercury vapour.In the time reducing the electric energy of input, can reduce the probability that gas excites, reach the effect that reduces output light flux.That is, with the light modulation module of this principle design, input electric energy by reduction, and can keep good luminous efficiency, reach the effect of energy-saving dimming, also can not affect its useful life simultaneously.
Compared with prior art, ceramic electrode electricity-saving lamp described in the utility model, tool has the following advantages:
1. adopt ceramic electrode to substitute traditional filament and electronic powder, can not produce sputter and electronic powder and consume too fast phenomenon, can significantly extend the useful life of electricity-saving lamp;
2. in life-saving, because adopt ceramic material cheaply, can reduce on the whole the production cost of electricity-saving lamp.
3. input the size of electric energy by adjusting, can realize the effect of energy-saving dimming.

Embodiment
Below in conjunction with accompanying drawing, specific embodiment in the utility model is described in further detail.
As above shown in Fig. 1, a kind of ceramic electrode electricity-saving lamp, comprises lamp holder 1, and connector 2 is provided with electronic ballast components in connector 2; Fluorescent tube 3 is connected with lamp holder by connector, and described fluorescent tube 3 comprises that inwall scribbles the tube cell 5 of fluorescent material, is arranged on the ceramic electrode 4 at tube cell 5 two ends, and is placed on the amalgam 6 in tube cell 5.In the present embodiment, above-mentioned tube cell 5 is helix tube, and caliber is 10mm, belongs to slim pipe diameter fluorescent tube.
As Figure 2-3, above-mentioned ceramic electrode 4 is a tubular earthenware, on the inwall at ceramic electrode 4 two ends, be respectively equipped with a concave step 41 and 42, two ports of tube cell are arranged on respectively in the concave step 42 of ceramic electrode one end, and blast pipe is arranged in the concave step 41 of the ceramic electrode other end.Be that ceramic electrode 4 wraps tube cell 5 and blast pipe 7 by the concave step at two ends, and seal by inorganic adhesive, by exhaust air technique, tube cell inside is filled with to certain pressure inert gas, and places the amalgam that an intragranular is put.And then sealing is blown in blast pipe one end.Above-mentioned inorganic adhesive is made up of low glass powder, inorganic oxide.Above-mentioned ceramic electrode 4 is mainly formed by inorganic oxide and glass mixed sintering, and specifically, by 55% high-purity a-Al2O3 polycrystal alumina powder, 35% nano Mo powder and 10% tungsten powder high-temperature firing form.
