Abstract
The utility model relates to a multilateral helical fluorescent lamp, a helical bending glass tube of which is formed by the sequential distribution of a plurality of shorter straight-tube typed glass tubes and shorter arc glass tubes, so as to form a multilateral helical structure. The bending of the multilateral helical glass tube reduces energy consumption by about 80 percent comparing with the conventional helical glass tube. The multilateral helical glass tube facilitates the realization of the mechanization and automation of the bending process, effectively improves the bending quality and reduces the bending cost; wherein, the arc bending tube part between two adjacent short straight tubes can form effective 'cold end' when discharging, thus improving the luminous efficiency. Furthermore, the multilateral helical fluorescent lamp can be made into the energy saving lighting source with various specifications.
Description
Technical field
The present invention relates to a kind of compact fluorescent lamp, especially a kind of its glass-tube is shaped as the compact fluorescent lamp of multilateral helical.
Background technology
Compact fluorescent lamp (Compact Fluorescent Lamp) abbreviates CFL as, is come out in 1979.PHILIPS Co. released at that time " PL " type (claiming " H " type again) and two kinds of CFL of " SL " type.Afterwards, CFL is developed rapidly in China, and using maximum is " 2U " type and many " U " type CFL such as " 3U " type.Reach 80% more than owing to replace the incandescent lamp bulb of extensive use to economize on electricity, so generically be referred to as electricity-saving lamp by people with CFL.
At present, many " U " type CFL such as " 2U ", " 3U " are very ripe in the technology that China produces in enormous quantities, and annual production surpasses 1,000,000,000 more than, accounts for more than 80% of world's total amount.But there is the shortcoming of a band essence in it, that is exactly connection between " U " shape glass-tube all by " connecing bridge ", this not only makes production process increase, and " connects bridge " even more noteworthy and locates relatively to be easy to burst and brittle failure, has reduced reliability of products significantly.
Nineteen ninety-five, U.S. GE company has released helical florescent lamp (being designated hereinafter simply as the spiral lamp), be a kind of glass-tube to be curved spiral CFL, the compact degree that its glass-tube distributes is not second to " 3U " many U type CFL such as " 4U ", form yet but only once bend with a glass-tube, the trouble that does not have repeatedly " connecing bridge " possesses a drawback with the institute that " connecing bridge " brings, and fluorescent tube is firm and attractive in appearance.Therefore, the spiral lamp obtains people's favor (consulting collection of thesis " Symposium ProceedingsLS:7 " P61 of nineteen ninety-five the 7th international light source science and technology seminar) once being born.
The spiral lamp that GE company releases, its outline is similar to bulb-shaped, though very attractive in appearance, be not easy to produce in enormous quantities, therefore do not obtain promoting.The spiral lamp passes to China, made into the structure that outline is " cylindrical " or " taper shape ", thereby solved bend pipe problem of producing in enormous quantities and the problem that is coated with fluorescent material, China's spiral lamp developed rapidly and become the CFL new varieties that a kind of volume of production and marketing increases year by year fast.
Though the volume of production and marketing of China's spiral lamp is just increasing, have a gratifying situation, its development still is subjected to the restriction of following factor.The bend pipe that at first is the spirality glass-tube still is manual operation, and the technology of mechanization automatic bend pipe fails really to break through, and a large amount of artificial poor efficiency productions the cost of labor of bend pipe is raise, and quality conformance can not get guaranteeing; In addition, need during bend pipe to be heated to rubescent and abundant softening to whole glass-tube, energy resource consumption is very surprising, and this not only makes cost increase, and enlarging markedly of energy consumption also is the serious problems of making us can not be ignored in the production.
Summary of the invention
Purpose of the present invention is exactly the two big shortcomings that will fundamentally solve above-mentioned spiral lamp, be by changing the structure of spiral lamp, and make it be easy to realize that the mechanization of spiral lamp bend pipe produces the energy consumption when also wanting to reduce bend pipe significantly simultaneously automatically.
The solution of the present invention be will existing spiral lamp crooked twist glass-tube, change into the multilateral helical glass-tube that the glass-tube [2] by some short straight tube shape glass-tubes [1] and short arc-shaped bend distributes and forms successively.When bending this glass-tube, as long as to needing crooked glass-tube position heating between the two adjacent short straight tubes, the angular bend of determining by design when it is able to diastrophic softening degree just can make whole glass-tube progressively be configured as the multilateral helical glass-tube that is distributed successively and formed by some short straight tube shape glass-tubes and short arc glass-tube.Finish after the whole bent tube technique, this multilateral helical glass-tube is carried out conventional CFL lamp manufacturing process just can make multilateral helical florescent lamp (hereinafter to be referred as polygon spiral lamp).
Adopt after the such scheme, owing to be to add thermal ampoule with interval to local softening, and only at heating position bend pipe, heating part still is not a straight tube, just adopts machine to finish the bend pipe action easily, realizes the machine automatic bend pipe; Also owing to be that glass-tube is heated with interval, for example making the heated glass-tube part (being arc glass-tube part) and the length ratio of the glass-tube part (being straight tube shape glass-tube part) that does not heat is 1 to 5, this needs the whole required energy consumption of glass-tube heating reduced about 80% when adding the existing spiral lamp bend pipe of the required energy loss-rate of thermal ampoule in the time of will making bend pipe, thereby obtains the effect that cuts down the consumption of energy significantly.
In order to satisfy different user's requests, the short straight tube part in the multilateral helical glass-tube is changeable, and straight-tube portion is long more, and the polygon feature is obvious more; Straight-tube portion is short more, and the polygon feature is not obvious more, approaching more existing slick and sly spirality glass-tube, and the length of short straight tube part and the span of glass-tube diameter ratio are 0.5 to 10.In addition, with existing spiral lamp ﹠ lantern seemingly, the polygon spiral lamp of the invention also can be made " cylindricality ", " taper ", " parallel arms " and versions such as " cross legs ": the design feature of " cylindricality " polygon spiral lamp is, to the fluorescent tube afterbody 4 that lead-out wire is housed, its each circle glass-tube equates around the radius that the axis of screw rotates from the top 3 of polygon spiral lamp; The design feature of " taper " polygon spiral lamp is, to the fluorescent tube afterbody 4 that lead-out wire is housed, the radius that its each circle glass-tube rotates around the axis of screw is progressively to become big from the top 3 of polygon spiral lamp; The design feature of " parallel arms " polygon spiral lamp is that the fluorescent tube afterbody 4 that lead-out wire is housed of its fluorescent tube is shaped as the straight tube that is parallel to the axis of screw; The design feature of " cross leg " polygon spiral lamp is that the fluorescent tube afterbody 4 that lead-out wire is housed of its fluorescent tube is shaped as and axis of screw straight tube at an angle.
The span broad of the glass tube outer diameter of multilateral helical florescent lamp can be 2 millimeters to 26 millimeters.Wherein cold-cathode fluorescence lamp is 2 millimeters to 4 millimeters; Hot-cathode fluorescent lamp is 5 millimeters to 26 millimeters.
