The high power fluorescent lamp of the utility model is composed of a lamp filament (1), a lamp tube (5), fluorescent powder (6), a positive electrode (2), a lamp filament support frame (7) and a thermal shield (4), wherein the lamp filament (1) is installed and fixed at both ends of the lamp tube (5) and extended to the outside of the lamp tube (5) by the lamp filament support frame (7), and the thermal shield (4) is sheathed between the lamp filament (1) and a core post. The utility model is characterized in that the positive electrode (2) forms an annular shape, the positive electrode (2) is fixed and wound around the lamp filament (1) by a support rod (3). The utility model has the advantages of simple structure of a lamp wick, simple manufacture, low cost, high qualification rate, etc. and has the advantages that the utility model can control mercury pollution and protect the body health of staff, etc.
Description
The high-power fluorescent lamp of a kind of power more than 100W belongs to electric consumption on lighting vacuum device field.
Make the high-power fluorescent lamp of power more than 100W at present, the problem that at first runs into is how to prevent that mercury vapor pressure from increasing because of thermal losses, make light efficiency reduce, that is when lamp current density is increased to a certain degree continuation increase again, the light efficiency of lamp can reduce on the contrary, this is because when current density increases, and the probability increase owing to the second class inelastic collision in the lamp reduces 253.7 millimicrons radiation, is excited to 6 on the other hand
3P
1The atom of energy level also may be excited to higher energy level with electron collision, is in 6
3P
1The atom life-span of attitude is long, so when current density increased, this situation odds was just big, thereby ultra-violet radiation efficient just reduces, though strengthened power so increase the electric current of lamp, ultra-violet radiation and not obvious increase, the light efficiency of lamp reduces with the increase of lamp power on the contrary.
In order to address this problem, the at present domestic practice that generally adopts is:
The one, select the argon-mixed replacement straight argon of neon to improve electron temperature;
The 2nd, increase heat shield and control cold junction temperature;
The 3rd, sheet or shaft-like metal anode are housed near filament, in playing half period of anodize, electrode receives electronics, with the bombardment that reduces the duplet cathode with reduce anode fall, and help reducing the pipe end blackout.
The problem that this way exists is:
1, need at first heat shield sheet or shaft-like anode to be carried out mechanical compaction, chemical cleaning, thereby selection is particular about, high, the complex procedures of cost.
2, when wick is assembled, every lamp need increase by 8 solder joints, and efficiency is low, and only solder joint comes off and influences just reaching about 4% of qualification rate in system lamp process.
3, this lamp adopts and directly annotates mercury when producing, and the mercury vapor pressure height is imitated light and reduced, and contaminated environment, and the harm operating personnel are healthy.
The purpose of this utility model just is to overcome the deficiency that prior art exists, and provides a kind of simple in structure, easy to assembly, and the efficiency height can be controlled the high-power fluorescent lamp of mercury pollution.
The purpose of this utility model realizes in the following way:
High-power fluorescent lamp, form by filament (1), fluorescent tube (5), fluorescent material (6), anode (2), filament support (7), heat shield (4), filament (1) is fixed on fluorescent tube (5) two ends by filament support (7) and extends to outside the fluorescent tube (5), heat shield (4) is sleeved between filament (1) and the stem stem, it is characterized in that: anode (2) is ring-type, by support bar (3) retainer ring around filament (1) on every side.
The purpose of this utility model also can realize in the following way:
When distance extends between filament (1) and stem stem, can save heat shield (4).
Orificed anode (2) is to make with titanium amalgam-zirconium aluminium 16, also can adopt nickel sheet or nickel plating iron plate or stainless steel substrates to make, but when adopting nickel sheet or nickel plating iron plate or stainless steel substrates to make orificed anode, still need annotate mercury in the technology.
High-power fluorescent lamp of the present utility model has adopted orificed anode, and employing titanium amalgam-zirconium aluminium 16 materials, solved the wick structure complex process of the high-power fluorescent lamp that solves of failing for a long time, production efficiency is low, the cost height, the life-span is short, Yi Heihuang, and annotate the mercury pollution environment, damage two healthy hang-ups of operating personnel.
Fig. 1 is the utility model high-power fluorescent lamp wick structure schematic diagram;
Fig. 2 be the utility model high-power fluorescent lamp wick structure anode 2 with stem stem apart from lengthening after, the structural representation when omitting heat shield 4;
Fig. 3 is the utility model high-power fluorescent lamp structural representation;
Fig. 4 is the structural representation that former high-power fluorescent lamp anode is the mica catch;
Fig. 5 is that former high-power fluorescent lamp anode is shaft-like structural representation;
Fig. 6 is the structural representation that former high-power fluorescent lamp anode is a sheet;
Among Fig. 1-6: 10 mica catch, the 11 shaft-like anode 12 sheet anodes of 1 filament, 2 orificed anodes, 3 support bars, 4 heat shields, 5 fluorescent tubes, 6 fluorescent material, 7 filament supports, 8,9 lamp angles.
Fig. 1 is the utility model high-power fluorescent lamp wick structure most preferred embodiment.Below in conjunction with accompanying drawing high-power fluorescent lamp of the present utility model is described in further detail:
The wick structure of the high-power fluorescent lamp of Zhi Zuoing is installed in the fluorescent tube 5 of Fig. 3 as shown in Figure 1, result of use the best.
Compared with prior art the advantage that has of the utility model high-power fluorescent lamp is:
1, adopt the orificed anode structure, simple in structure, easily to make, solder joint is few, removes heat screen, and solder joint only is 2, has greatly improved efficiency, reduces cost 5%, and qualification rate improves more than 3%.
2, adopt titanium amalgam-zirconium aluminium 16 absorbing gas belts to do orificed anode, because of the synthermal pure mercury saturated vapor pressure of amalgam saturated vapor pressure ratio much lower, can be under higher tube wall temperature, still can keep best steam pressure, remove the tube wall temperature rising that brings behind the heat screen thereby remedied, the problem that the mercury vapor pressure that makes raises reaches single light flux or a little higher than existing high-power fluorescent lamp.
3, zirconium aluminium 16 is getter, can adsorb foreign gas to improve vacuum in the lamp, than one times of existing high-power fluorescent lamp Service life in the lamp normal operation.
4, owing to adopt the titanium amalgam as " mercury source ", and " titanium amalgam " do not producing obvious release below 500 ℃, only make lamp after; when high-frequency heating arrives 870-900 ℃; mercury could be discharged, thereby reach the effect of control " mercury pollution ", the protection operating personnel are healthy.
