Description
Technical field
The utility model relates to lighting field, refers in particular to a kind of fluorescent tube.
Background technology
In recent years, power saving fluorescent lamp develops to superfine pipe diameter, high light efficiency direction.The glass-tube of current hot-cathode fluorescent lamp (HCFL) typically has a diameter from more than the Φ 7mm.Be subjected to the restriction in making of filamentray structure and technology for the superfine pipe diameter hot-cathode fluorescent lamp, the stem stem sealing technology of current routine is not suitable for the superfine pipe diameter fluorescent lamp.Though can adopt the bead sealing-in, on oxide coated cathode filament and the bead crimping of two seal wires very difficult, and filament easily and the glass wall collide.No matter adopt which kind of sealing technology, all compare difficulty.The hot-cathode fluorescent lamp of superfine pipe diameter is in cathode preheat and burning-point process simultaneously, and electrode evapotranspires and easily early stage blackout occurs at the tubule inwall, and current cold cathode electrode commonly used is made the superfine pipe diameter fluorescent lamp, i.e. cold-cathode fluorescence lamp (CCFL).The glass-tube diameter of CCFL is generally Φ 3-5mm, even thinner, and the superfine pipe diameter fluorescent lamp all adopts the bead guide wire, work under good state in order to ensure fluorescent tube, usually be connected to the thin glass tube that is equipped with amalgam separately at the tube cell wall, obviously make numerous and diversely, outward appearance is also not good.The metal electrode size of CCFL is limit by the glass-tube internal diameter simultaneously, and secondary emission surface is long-pending less, and temperature easily raises, and the sputter loss is obvious, and wall turns black in early days; Equally, if the electrode welding is crooked, easily bump the glass wall.The glass-tube diameter of external-electrode fluorescent lamp (EEFL) is generally Φ 4-8mm, it is to apply alternating electric field on the external electrode of glass-tube two ends, impel the operation material Discharge illuminating in the pipe, owing on the external electrode current delivery is arranged, current density is bigger, so it is higher to be somebody's turn to do place's glass wall and metal electrode temperature, cause the venting of glass wall, lamp works characteristic instability.
Summary of the invention
The utility model is just in order to overcome above-mentioned deficiency, a kind of production efficiency height is provided, technology is simple, luminous efficiency good, the fluorescent lamp tube with different diameter of tube of long service life, main innovation is that the pin glass-tube of lamp tube electrode position glass-tube or electrodeless fluorescent tube is made thick glass-tube, and the main body glass-tube is made as superfine pipe diameter.It specifically is to implement like this: fluorescent lamp tube with different diameter of tube, there is the fluorescent tube utmost point or electrodeless to comprise glass-tube, stem stem, the glass-tube inwall scribbles phosphor powder layer, it is characterized in that glass-tube is made up of main body glass-tube and pin glass-tube, the main body glass-tube is a tubule footpath glass-tube, it is extra heavy pipe footpath glass-tube that the pin electrode area glass-tube of utmost point fluorescent tube or the pin glass-tube of electrodeless fluorescent tube are arranged, and thick, thin glass tube is conjoined structure, and the caliber between described thin glass tube and thick glass-tube differs 1-4mm.
Main body glass-tube diameter as thin glass tube in the utility model is Φ 2.5-8mm, and general thin glass tube diameter is Φ 2.5-5.5mm, and during as EEFL, the diameter of thin glass tube can be 5.5-8mm more greatly.
To the electrode that utmost point fluorescent tube is arranged be respectively: fluorescent lamp hot cathode, cold cathode, external electrode, electrodeless and combination electrode all is suitable for; Described fluorescent tube is the fluorescent tube of shapes such as spirality, straight tube shape, U-shaped, L shaped, W shape or annular, all in protection scope of the present invention.
In the utility model, the connection of different diameter adopts different diameter docking technique or thin glass tube directly to expand thick means:
The different diameter docking technique is the thick glass-tube rotation and the heating docking port end that will dock, and reducing is extremely close with thin glass tube footpath size, slowly docks with the short pin thin glass tube that rotates with speed subsequently, makes annealing in process to after connecting.
It is that directly the rotation heating will increase thick thin glass tube that thin glass tube directly expands thick means, slowly is advanced into one heart in the thin glass tube with speed with the thick rod of being with conical head, and to inflate effect better for the limit heating edge in the thin glass tube.
Said process can be finished by hand, also can design corresponding semi-automatic or automatic equipment and finish this butt joint technology.Manual efficient is low, and the consistency difference is a little; And the service of connection devices effect height, high conformity, equipment cost is expensive.
The beneficial effects of the utility model are:
1, increases near the glass-tube diameter of electrode, adopt the common process of current compact fluorescent lamp, utilize the direct sealing-in of stem stem and phosphor powder tube, can simplify production technology, enhance productivity greatly.Current very ripe HCFL technology and equipment all can be applied to make the fluorescent lamp of different diameter, greatly reduces the production cost of investment, improves utilization rate of equipment and installations;
2, the increase of electrode area glass caliber can allow electrode area suitably increase, and not only wall surface temperature can reduce, and the operating state of fluorescent tube improves.The loss of sputter simultaneously reduces, and the wall probability that turns black in early days reduces; Electrode also significantly reduces with the probability that the glass wall touches mutually, and the rate that manufactures a finished product improves, thereby has improved the luminous efficiency of fluorescent tube, life-saving.
3, behind the employing stem stem, have blast pipe in it, when working in than high ambient temperature for fluorescent tube, the setting of amalgam position is greatly simplified.In the superfine pipe diameter fluorescent lamp of bead guide wire, overcome and put the numerous and diverse shortcoming of mercury technology.
4, the electrode area of CCFL and EEFL increases, and can reduce anode fall, reduces the working temperature of electrode.
5, adopt the tube cell of extra heavy pipe pin can use conventional stem stem, overcome the restriction in the manufacturing of filament electrode structure and process for sealing.The method that extra heavy pipe pin tubule directly provides a kind of hot-cathode fluorescent lamp (HCFL) to realize superfine pipe diameterization, and need not special equipment, greatly improved the utilance of existing equipment.
