CN2182459Y - Three-connector type long-life lamp tube - Google Patents

Abstract

The utility model relates to a three-connector type durable lamp tube having long service life. According to the existing design principle of the lamp tube, the two outer ends of the existing lamp tube are respectively added by spare wiring terminals, and the two spare wiring terminals extend into the lamp tube. The inner two ends of the lamp tube are respectively added by spare filaments, one end of the lamp tube is connected with the spare wiring terminals extending into the lamp tube, the other end of the lamp tube is connected with a common wire terminal inside the lamp tube, and the spare filaments are arranged in a front and back mode with original filaments in the included angle of 60 DEG. Thereby, the lamp tube can not emit light when one group of filaments is burned out or the electronical emitting materials on the filaments are exhausted. The spare filaments can be started to make the lamp tube work continuously only if the lamp tube is taken off and installed again after the two wiring terminals connected with the spare filaments are inserted into the power supply holes.

Description

Three-connector type long-life lamp tube

The utility model relates to a kind of fluorescent tube---the three joint type long service life lamp tubes that a kind of useful life is very long.

At present, known fluorescent tube is made up of lamp holder, filament, glass bulb.As fluorescent tube, two insulation spacer inboards by two alloys outside cap fasten the glass-tube that a column, inwall scribble fluorescent material and be filled with an amount of argon gas and mercury, form an airtight space, at these glass-tube two ends, by fix two parallel wires posts by an insulation spacer, and stretch in the pipe an amount of one section (it is further fixing to condense into column by glass) two binding posts of every end accordingly and join with the two ends that are arranged on a filament at two ends in the pipe, energising can be luminous.But, the useful life of fluorescent tube is desirable not enough, often be difficult to reach the useful life of specified 2000--5000 hour (power of lamp tube difference, life time is different), even reach, die of old age, analyze its reason, in scrapping fluorescent tube more than 80%, glass bulb and auxiliary member all can continue to use, and the exhausting of electronic emitting material on filament scaling loss or the filament then is fatal problem.

The purpose of this utility model provides a kind of according to existing fluorescent tube design principle, to existing fluorescent tube auxiliary member and the improved a little technology of internal structure, can reach the novel long service life lamp tube of prolonging lamp tube useful life (fluorescent tube after the improvement is 2 times of existing fluorescent tube useful life).

The purpose of this utility model be achieved in that (being example with the fluorescent tube) two insulation spacer inboards by two alloys outside cap fasten a column, inwall scribbles fluorescent material and is filled with the glass-tube of an amount of argon gas and mercury, form an airtight space, at these glass-tube two ends, by fix two parallel wires posts by an insulation spacer, and stretch in the pipe an amount of one section (it is further fixing to condense into column by glass) every section two binding posts accordingly and join with the two ends that are arranged on a filament at two ends in the pipe, in this lamp tube ends, each increases a standby binding post, and in the inlet tube, two ends in fluorescent tube, each increases a standby filament, standby binding post in one end and the inlet tube joins, a binding post in the other end and the former pipe join (public binding post), and be and arrange that (wherein the binding post of one group of filament can suitably be grown before and after the 60 degree angles with filament in the former pipe, to reduce the power on consumption of sub-emitting material of back filament of being heated of standby filament), can be luminous after the energising.Article two, three binding posts of filament, one of them is the public binding post of two filaments; Electronic emitting material exhausts on one group of filament scaling loss of working in this way or the filament, fluorescent tube is not luminous, as long as fluorescent tube is taken off, two binding posts that connect standby filament are inserted power hole, can start standby filament, making it to work on, (certain and supporting lamp base of fluorescent tube also needs become three by two original wiring hole increases, be the equilateral triangle shape), fluorescent tube has just reached the purpose of longevity like this.

Owing to adopt such scheme, prolonged fluorescent tube useful life fully, only outside existing fluorescent tube, increased a winding terminal newly, in fluorescent tube, increased one group of standby filament newly, simple in structure.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a front view of the present utility model.

Fig. 2 is a left view of the present utility model.

Fig. 3 is the sectional arrangement drawing of the utility model embodiment.

Among the figure 1, the glass column 8 of public binding post 2, main terminal 3, standby binding post 4, standby filament 5, main filament 6, the outer cap 7 of alloy, link post, glass bulb 9, fluorescent material 10, an amount of argon gas and mercury 11, insulation spacer.

In the embodiment shown in fig. 3, public binding post (1) is by insulation spacer (11), the outer cap (6) of alloy and glass column (7) stretches in the glass bulb and an end of main filament (5) joins, and the other end of main filament (5) joins with the main terminal (2) that in kind stretches in the glass bulb; One end of standby filament (4) joins with the public binding post (1) that stretches in the glass bulb, and the other end joins with the standby binding post (3) that stretches in the glass bulb.(fluorescent tube right-hand member structure with a left side) like this, after the energized, main filament (5) the electrons emitted accelerated motion under the high-tension effect of lamp tube ends of being heated, argon gas heat release simultaneously in the collision fluorescent tube, also be ionized after making the mercury evaporation in the pipe, send the light-emitting phosphor of strong ultraviolet ray excited inside pipe wall.Electronics material on main filament (5) scaling loss or filament exhausts, and main terminal (2) lost efficacy; At this moment, fluorescent tube is taken off, two binding posts (1) that connect standby filament and (3) insertion power hole are loaded onto again, can start standby filament (4), fluorescent tube is worked on.

Claims (3)

1, a kind of three joint type long service life lamp tubes, two insulation spacer inboards by two alloys outside cap fasten a column, inwall scribbles fluorescent material and is filled with the glass-tube of an amount of argon gas and mercury, form an airtight space, at these glass-tube two ends, by fix two parallel wires posts by an insulation spacer, and stretch into one section an amount of in the glass-tube accordingly, two binding posts of every end join with the two ends that are arranged on a filament at two ends in the pipe, it is characterized in that: the glass-tube two ends respectively increase a standby binding post, and stretch in the glass-tube accordingly, a standby filament is respectively set up at two ends in pipe, standby binding post in one end of filament and the inlet tube joins, and a public binding post in the other end and the former pipe joins.
