The compact type fluorescent lamp is a real no-bridge multi-pipe compact type fluorescent lamp.

Description

Compact fluorescent lamp

Technical field

Utility model is about the multitube compact fluorescent lamp tube being connected to form the improvement of discharge channel, relating in particular to a kind of multitube compact fluorescent lamp of non-jointing bridge.

Background technology

People are for shortening the length of fluorescent lamp, and use and easy for installation, adopt crooked multitube combination compact fluorescent lamp tube structure, for example the curved tabs pipe connect bridge and form as multiple shapes such as H, U, W, make fluorescent tube banded luminous to become concentration of local luminous.Compact fluorescent lamp in process of production, for being communicated with, many curved tabs pipes form discharge channel, almost all take the flame welding, be commonly called as " bridge joint ", two or above curved tabs pipe of end closure (being commonly called as tack) soon gone up, melting connection from the position of pipe end 1-1.5cm blast hole, burning, making each sheet pipe form the discharge channel that is communicated with.This kind is connected to form discharge channel by " connecing bridge ", its deficiency: the cross structure aperture is thin many than the fluorescent tube aperture, and bridge opening is less than 1/2 of fluorescent tube caliber usually, not only cause the tube wall load to strengthen, pipe voltage rise height, light efficiency descends, light decay strengthens, and shorten actual life; And optical channel is not smooth, and this position about 500 hours, will produce burnt hair blackout phenomenon in various degree in lamp works, causes reduce useful life.Secondly, fuse and connect bridge and cause this part almost transparent (no fluorescent material), when lamp tube starting work, bridge location partly in a large number ultraviolet lights separate out and cause light pollution.In addition, connecing bridging connects, must be that two pipes are parallel, and connect the bridge distance and generally can not surpass 3mm, can not the shift position between adjacent big distance, two pipes and overlapping abnormal shape etc., then can not connect, therefore limit the diversity of fluorescent lamp variation in moulding by connecing bridging, so the actual moulding of compact fluorescent lamp and few.Besides, bridge process is cold the most serious quick-fried operation, connects bridge and fuses to cause and sealed fluorescent tube and burst, and causes qualification rate to descend, and increases production cost, whenever connects the once cold fried rate of bridge usually and reaches 3-4%, is combined as routine loss late with 4 pipes and reaches 8-10%.Connecing bridge top not luminous is the dark space, causes the loss of fluorescent tube total light flux more than 2%.Therefore connect bridge lamp fluorescent lamp, light efficiency is low, and the life-span is short, and consistency is poor, and style is with low uncertainty, the bridging process complexity, and rate of finished products is lower, has become compact fluorescent lamp and has been difficult to go beyond technical barrier.

Though prior art discloses the non-jointing bridge compact fluorescent lamp, the electronic energy-saving lamp of disclosed double-row type of Chinese patent CN2271656 or three row formulas for example, with two or three compact fluorescent lamp tube of single-ended bending independently, non-jointing bridge is assembled on the electronic energy-saving lamp.But to be each fluorescent tube independently light for this, makes rectifier become complicated, increased the rectifier cost, and multitube lights respectively, photochromic be not easy unified.

The utility model content

The utility model purpose is to overcome the deficiency of above-mentioned prior art, provides a kind of variation in moulding big, light efficiency height, the compact fluorescent lamp of long service life.

The utility model purpose realizes, the main improvement is that multitube UNICOM forms discharge channel and adopts curve bend to connect, and by glass dust through hot melt adhesion, form the gastight discharge channel of sealing, overcome above-mentioned the deficiencies in the prior art, realize the utility model purpose.Utility model compact fluorescent lamp specifically, comprise two or the above curved tabs pipe formation discharge channel that is interconnected, it is characterized in that it is the crooked glass-tube socket or the connection of pegging graft that adjacent flex sheet pipe is communicated with, and, form the air-tightness sealing-in by the glass powder with low melting point hot melt adhesion.

Utility model said arc glass-tube socket or grafting, coupling part can in be placed in fluorescent tube, also can connect by the overcoat mode, lap applies the glass dust slurry that is lower than the fluorescent glass tubes fusing point, through heating for example about 450 ℃, thereby make the glass powder with low melting point fusion with both one that bonds, form gastight sealing-in.

The crooked glass-tube of said connection adjacent sheet pipe, its curved shape is decided according to forming the lamp shape, for example can be meant crooked U type or other arc short-movie pipes, for simplifying technological operation, a kind of better is crooked glass-tube, reaches to connect to connect after the curved tabs pipe is coated fluorescent material again.

The utility model compact fluorescent lamp, owing to adopt crooked glass-tube to connect two adjacent sheet pipes, thereby real no bridge multitube compact fluorescent lamp, have than prior art: the cross section, connected pore channel is big, basic near or surpass and light fluorescent tube, thoroughly changed the former narrow defect of seizing by the throat of bridge fluorescent tube optical channel that connects, luminous flux, quality and the actual life of fluorescent tube have been improved, high conformity, connecting portion fluorescent material is uninterrupted, does not also have light pollution and produces; Be communicated with the cold conditions butt joint, hot melting cohesion does not have cold quick-friedly, and technology is simple, and the rate of finished products height owing to simplified mode of communicating, has improved rate of finished products, and cost remains basically stable; Luminous invariably dark space, the whole length of fluorescent tube are effective length of illumination, have also improved light efficiency; Socket of arc glass-tube or grafting, form omnipotent connection, can develop any imagination moulding kind, Idiotype fluorescent lamp particularly, improved the compact fluorescent lamp variation in moulding greatly, can produce the various moulding that former bridge joint can't be accomplished, improve the practicality and the decoration functions of multi-tube fluorescent lamp.Better solved the technical barrier that compact fluorescent lamp runs into.

Below in conjunction with some specific embodiments; utility model is further understood in exemplary illustration and help; but the embodiment detail only is for utility model is described; do not represent utility model design whole technical schemes down; therefore should not be construed as the technical scheme qualification total to utility model, some do not depart from the unsubstantiality of utility model design and change In the view of the technical staff; for example change or replace, all truely use novel protected scope so that technical characterictic with same or similar technique effect is simple.
