Description
The present invention relates to a kind of helical type florescent lamp, especially a kind of in lampshade/shell the upside-down assembling helical florescent lamp of upside-down mounting helical fluorescent lamp tube.
Helical type florescent lamp (being designated hereinafter simply as the spiral lamp) was come out in nineteen ninety-five, and is firm and aesthetic in appearance because its compact conformation, obtains people's approval soon and develops rapidly.At present, no matter be hot cathode spiral lamp or cold cathode spiral lamp, it is in the equal fast rise year by year of the year of China volume of production and marketing, and people estimate, and in the near future, the application of spiral lamp in room lighting will jump rapidly to first of all kinds of compact fluorescent lamps.
In the spiral lamp, having a kind of is with pack into band cover/shell spiral lamp among tubaeform lampshade/shell of helical fluorescent lamp tube; Perhaps, fuse with electric ballast/inverter again and form integrated band cover/shell electron helical lamp.Because the inner surface of lampshade/shell usually is the very high glossy surface of luminous reflectivity, this band cover/shell spiral lamp has good directional lighting effect, can effectively improve the illumination of photographed object, is widely used.For example, high-power (band of 60W-200W) cover/shell electron helical lamp, the energy-saving illumination of very suitable factory, market, meeting-place and stadiums wherein; Its middle low power (small-sized reflector lamp of pack into cold cathode spiral fluorescent tube or the hot cathode superfine pipe diameter T2 fluorescent tube of 3W-7W), also more and more be used for replacing the 25W-50W halogen reflector lamp in the decorative lighting, economize on electricity 80% to 90% more than gains great popularity.
Yet, helical lampl in existing band cover/shell electron helical lamp all be outline cylindrical (consult Fig. 1. and Zhejiang Sunshine Group product type YPZ220/43.S.D162) wherein no matter be to adopt band cover electron helical lamp thermal cathode fluorescent tube or cathode fluorescent tube, so far there is a unsolved difficult problem, that is exactly that the power of lamp is big not enough, luminous flux is high not enough, is difficult to further improve power, light efficiency and the luminous flux of lamp.For example, aforesaid high-power band cover electron helical lamp can reach greater than the higher light efficiency of 60Lm/W at present, and its power is all below 80W.And nearly all high-power spiral lamp lamp power after lighting all constantly descends, the power of lamp tube after burning-point is stablized often reduce to less than 100W! A lot of application scenarios need the high-power band cover electron helical lamp of the high light efficiency of 100W, 150W, 200W even 300W; The and for example aforesaid small-power reflector lamp made from cathode fluorescent tube also feels generally that its luminous flux and light efficiency need further to improve, and for example requires its power to bring up to 7W-9W from present about 4W; Light efficiency is brought up to greater than 30Lm/W from present 20Lm/W-25Lm/W; Output light flux is brought up to greater than 200Lm or the like from existing about 100Lm.
Purpose of the present invention will solve an above-mentioned difficult problem exactly, makes more powerful, the light efficiency of band cover electron helical lamp and luminous flux higher, thereby is more widely used and obtains better energy-saving effect.
The objective of the invention is to realize by following scheme.
Through to the in-depth analysis of fluorescent lamp principle and a large amount of experiments at spiral fluorescent lamp, the conclusion that draws is: desire to improve effectively the power and the light efficiency of high-power spiral lamp, the glass-tube length and the interior mercury vapor pressure of control fluorescent tube that must increase fluorescent tube as much as possible are near the optimum value.In view of the above, the outline of helical type lamp is made similar to the shape of lampshade/shell tubaeform, can be increased the glass-tube length of fluorescent tube to greatest extent and obtain maximum power of lamp tube and luminous flux; Simultaneously, pick out a bit of glass-tube [10] at the top of helical lampl, in adorn high/medium/low temperature amalgam (determining use which kind of amalgam) according to actual temperature, the interior mercury vapor pressure of fluorescent tube is optimum value and can obtains the highest light efficiency during the control lamp works.Yet fluorescent tube mounting structure routinely, this tubaeform fluorescent tube similar to the lampshade shape can't be packed among the tubaeform lampshade, have only the reversing end to end of fluorescent tube, just with tubaeform helical lampl upside-down mounting among lampshade.The big opening end [8] (promptly near horn mouth) of the fluorescent tube afterbody [6] of lead-out wire near tubaeform lampshade specifically will be housed exactly, the top of helical lampl [5] then is contained in the osculum end [7] of tubaeform lampshade, the osculum end that lampshade is guided on the inside/outside surface that the lead-out wire [9] of fluorescent tube two tail ends is pressed close to lampshade into is connected with the output of electric ballast/inverter, becomes the upside-down assembling helical florescent lamp (see figure 2) with outstanding design feature and feature performance benefit.Analysis shows that with test through good lamp tube structure design and lighting tube production technology, the comparable existing similar products of the power of described upside-down assembling helical florescent lamp improve more than 50%, and light efficiency improves more than 15%, and output light flux improves more than 80%.
Except that above-mentioned, for the incorporate whole lamp of fluorescent tube, lampshade and electric ballast, adopt the structure of upside-down mounting helical lampl of the present invention can also reduce the heat transfer of fluorescent tube significantly to electric ballast, can effectively reduce the working temperature of electric ballast, improve the reliability of its work and prolong its useful life.Reason is conspicuous: no matter be hot-cathode fluorescent lamp or cold-cathode fluorescence lamp, the fluorescent tube afterbody of electrode always is equipped with at the position that lamp hole temperature is the highest.The electron helical lamp of ordinary construction, all be that the fluorescent tube afterbody that this temperature is the highest is installed near electric ballast, though this conventional structure that fluorescent tube is installed makes line convenience between fluorescent tube and the electric ballast, the high temperature of fluorescent tube afterbody then makes the working temperature of electric ballast raise significantly to the baking effect that the heat transfer of electric ballast produces, and its useful life and reliability then obviously descend; The structure of upside-down mounting fluorescent tube of the present invention is then opposite, and the very high fluorescent tube afterbody of temperature is near the horn mouth of lampshade/shell and away from electric ballast, makes fluorescent tube reduce to minimum to the electric ballast detrimental effect that is produced that conducts heat.Therefore, flip-over type spiral lamp is particularly conducive to and makes powerful integrated whole lamp.As is generally known, the client to be used, the installation of the high-power whole lamp of this integral structure is popular with using the most convenient, but the above electron helical lamp of the 80W of existing conventional structure dare not be made this integral structure for above-mentioned reasons.The above non-flip-over type of integrated electric spiral lamp of 100W does not belong to by contrast!
Except that above-mentioned, existing band cover electron helical type fluorescent lamp form the dazzling dazzle (as shown in Figure 1) of abstaining from very much, and flip-over type spiral lamp of the present invention can be eradicated this disadvantage (see figure 2) often because of fluorescent tube makes fluorescent tube expose lampshade than lampshade is long.
In sum, flip-over type spiral light fixture has high light efficiency, Gao Guangtong, highly reliable, free from glare, and plurality of advantages such as easy to use, is the very good energy-conserving light sources of a kind of market prospects.
