Abstract

The utility model provides an energy-saving fluorescent lamp whose structure is still uniform and compact when the power is increased. The utility model is characterized in that a fluorescent lamp tube is composed of two or more than two annular tubes which are linked into a concentric circle by bridging mode, the annular tubes can be collocated by columnar structure, annular structure, basin shape structure, or composite structure to fit different needs; the lamp tube is matched with an electronic or an induction ballast which is sheathed with a casing and a lamp cap, and an energy-saving lamp is formed, replacing the incandescent lamp.

Description

Concentric circle multi-ring type energy-saving fluorescent lamp

The utility model relates to lighting field, is a kind of low-pressure mercury yapour discharge lamp.

Present all kinds of compact energy-saving fluorescent lamp relies on its high light efficiency, the high colour developing and the little advantage of volume, and matching with electronics or Inductive ballast progressively replaces incandescent lamp bulb.But along with the increase of power of lamp tube, existing H type, U type can only merely increase its height, and ring-like, the 2D type can only merely increase its cross section, thereby makes the use of the electricity-saving lamp of these patterns be subjected to certain restriction.

The purpose of this utility model provides a kind of novel structure, and is still very well-balanced when power increases, compact power saving fluorescent lamp.

The utility model is to realize its purpose in the following manner, the ring-like effective mode that connects bridge that two or two above inwalls are scribbled phosphor powder layer is linked to be the concentric circles that several communicate, whole story of its passage end seal up the stem stem that has filament, all the other each end is in addition hermetic closed, makes fluorescent tube after exhaust.When needs increase power, when increasing discharge channel, then can be satisfied, thereby make the height of whole lamp and cross section can keep well-balanced property all the time from increasing ring-like external diameter of pipe and increasing by two approach of ring-like pipe radical.Central part with supporting ballast of this lamp and shell thereof then place the concentric circles fluorescent tube is also made full use of this part space, embodies the compactedness of lamp.

According to different use occasion needs, the ring-like pipe of forming above-mentioned fluorescent tube can have identical external diameter, stacks the formation column structure along short transverse; Also different external diameters can be arranged, the little annular of big ring sleeve structure circlewise in same plane; Marginal, then be external diameter slightly the ring-like pipe of difference form the peviform structure along the short transverse countersunk arrangement; Certainly, also can on the basis of above-mentioned three kinds of basic structures, be combined into other composite constructions.

Below in conjunction with accompanying drawing the utility model is further illustrated.

Figure one is an overall construction drawing of the present utility model, wherein shows lamp holder 1, housing 2, ballast 3 and fluorescent tube 4.

The top view of the fluorescent tube that figure two is made up of two ring-like pipes, inwall scribbles the ring-like pipe of phosphor powder layer and places in the concentric circles mode, is communicated with by connecing bridge 9, with

port

6 and 8 sealings, seal up the stem stem that has filament at

port

5 and 7 places, so just constituted two ring fluorescent lamp pipes.

The top view of the fluorescent tube that figure three is made up of three ring-like pipes.Only be that with two ring shaped lamp differences increase connects bridge 10, stem stem changed be enclosed in port one 2 places, simultaneously closed port 7 and 11.By that analogy, also can obtain the Fourth Ring pipe, the five rings pipe, or the like.

Figure four, figure five, figure six have shown the column of how ring-like power saving fluorescent lamps, ring-type, peviform structure respectively; Seven examples that show some composite constructions of figure.

The caliber of many ring shaped lamps is generally 8～28mm, can be selected according to factors such as power of lamp tube, voltage, length.Tube inner wall generally scribbles rare-earth trichromatic fluorescent powder, but for caliber thick (more than the φ 15mm), and tube wall is negative to cut a less (500w/m ²Below) fluorescent tube do not repel the use halogen calcium phosphate fluoressent powder yet so that reduce cost.

Many ring shaped lamps can have plug body, and are supporting with corresponding socket, fluorescent tube and ballast and shell thereof are tied, thereby form the electricity-saving lamp of interchangeable fluorescent tube.Many ring shaped lamps also can be with plug body, directly are assembled into integrated energy-saving lamp with custom-designed housing.

The ballast supporting with many ring shaped lamps can be electronic type, so that further embody the power consumptive province, lightweight advantage.But because the ballast and the shell thereof of how ring-like electricity-saving lamp are central part rather than the tops that places lamp, the volume of ballast and the requirement of shape are reduced, this just for using Inductive ballast, reduces the price of lamp and has created condition.Because many ring shaped lamps good looking appearance generally can be made into the exposed electricity-saving lamp of fluorescent tube, does not mix suitable spheric bulb but also do not repel, cylindrical bubble or light fixture outer cover are made the closed energy-saving lamp.

In order to further specify the effect of how ring-like electricity-saving lamp, can lift following utilization example: caliber φ 12.5mm, the double-H groove weld lamp of power 18w, the about 150mm of fluorescent tube length adds the ballast shell and the lamp holder of upper top, and length overall surpasses 180mm, seems not only thin but also long; Caliber φ 12.5mm, the 2D lamp of power 16w, cross section 140mm * 140mm seems bigger than normal; If adopt the tricyclic electricity-saving lamp of column structure, caliber is all φ 12.5mm, power is all 18w, then the fluorescent tube profile is diameter phi 65mm, the cylinder of height 45mm, and lamp holder is laid by central authorities at cylinder, ballast and shell, it highly is about 80mm, and global shape is very nearly the same with the 100w incandescent lamp bulb of same brightness, can be replaced use without difficulty in various light fixtures.

In sum, how ring-like electricity-saving lamp is rising electricity-saving lamp new varieties, and along with reaching its maturity of ring-like pipe pipe bending technique, it will be the same with existing H type, U type, 2D type electricity-saving lamp, used widely in the energy-saving illumination field.
