CN2524368Y - Dual amalagam bispiral fluorescent lamp - Google Patents

Abstract

The utility model discloses a dual amalgam bi-spiral fluorescent lamp. The lamp tube rotates at a same direction so as to form a bi-head spire; the two ends of the lamp tube are both provided with amalgams; the guide wires at the two ends of two groups of cathodes are fixed with vice amalgams. The lamp tube has two main amalgams and four vice amalgams so that the utility model has the characters of compact structure, short lamp tube starting time, rapid luminous flux establishment, convenient use and mounting, and little pollution to environment.

Description

Two amalgam, double helix fluorescent lamp

One, technical field

The utility model relates at fluorescent tube and is built-in with amalgam, and especially related fluorescent lamp tube is a spiral type.

Two, background technology

Energy-conservation and volume compact is widely used in illumination to compact fluorescent lamp because of it.Generally all be equipped with liquid mercury in the former fluorescent lamp tube, after liquid mercury is heated, be converted into gaseous state, after the energising, gaseous mercury is excited and sends ultraviolet ray, and bombardment is coated in the fluorescent material on the lamp tube wall, produces visible light.Stop to heat the back gaseous mercury and be converted into liquid mercury again, when fluorescent tube damaged, liquid mercury was overflowed, and can cause severe contamination to environment, so now adopt amalgam to replace liquid mercury.Amalgam is heated to more than 65 ℃, and the mercury in the amalgam is converted into gaseous mercury, and after the cooling of turning off the light, the mercury part in the fluorescent tube is absorbed by amalgam.Amalgam amount of vaporization at normal temperatures is minimum, has started the bright time for shortening fluorescent tube, is equipped with below negative electrode and pays amalgam.Pay amalgam system with containing the net sheet that indium metal is made, after the light-off, chilled mercury when fluorescent lamp restarts, attached to the mercury of paying on the amalgam, because of just heating up rapidly, gasify rapidly near negative electrode, enters normal operating conditions just attached to a pair amalgam surface.The area of paying amalgam is big, be stored in the mercury heating of paying on the amalgam after, gasification mercury amount is just big, can just reach luminance saturation at short notice.Existing product generally all will be paid on the seal wire that amalgam is fixed on negative electrode one end.It is inhomogeneous that such structure often makes the seal wire two ends of negative electrode be heated, and because the fluorescent tube space, makes the area of paying the amalgam monolithic can not be sufficiently large.It is longer to make fluorescent tube start the time that reaches luminance saturation.

Fluorescent lamp is in order to reach certain brightness, size according to power, fluorescent tube need have certain length, that now generally uses is yi word pattern, the fluorescent tube of U type, double-U-shaped, three U types had increased the single-screw fluorescent tube afterwards again, but had adopted the fluorescent tube of above-mentioned shape, its external form can't be done very for a short time, makes troubles to use.

Three, summary of the invention

The utility model aims to provide and a kind ofly is built-in with amalgam at fluorescent lamp tube, and the fluorescent lamp starting time is short, and it is logical to set up initial light fast, and the fluorescent lamp of contour structures compactness.

In conjunction with embodiment of the present utility model, existing that content introduction of the present utility model is as follows:

The utility model has helical type lamp (1) (1a), oxide coated cathode (2), pay amalgam (3) (3a), fluorescent coating (4), seal wire (5), stem stem (6), exhaust tubule (7), main amalgam compositions such as (8), it is characterized in that fluorescent tube (1) is (1a) all by the equidirectional biography of revolving, form twin-feed spiral, helical type lamp (1) other end connection (1a) communicates, fluorescent tube (a 1) end (1a) respectively is equipped with oxide coated cathode (2), paying amalgam (3) for two (3a) is separately fixed on two seal wires (5) at oxide coated cathode two ends, oxide coated cathode (2) links to each other with seal wire (5), exhaust tubule (7) one end and main amalgam (8) join, and the other end places in the stem stem (6).

When the utility model starts at fluorescent tube, since fluorescent tube when seasoned the former mercury that places the amalgam in the exhaust tubule attached to paying on the amalgam, so because heating of negative electrode, the mercury of paying in the amalgam is gasified rapidly, because the utility model has adopted two to pay amalgam, guaranteeing under the prerequisite that does not directly contact, the arrangement of paying amalgam can be fixed on by different orientation on the seal wire, make the area of paying amalgam can make bigger like this, simultaneously because all there is the amalgam of paying the both sides below negative electrode, so can make to be heated evenly, can shorten the mercury vapour time.The utility model has adopted the double helix of the equidirectional coiling of lamp tube ends in addition, makes the more compact structure of fluorescent tube.

Because the utility model has substituted liquid mercury with amalgam, so can reduce pollution, increase and pay the amalgam area environment, can shorten the time of fluorescent lamp starting, the instantaneous light of setting up leads to.And the utility model has adopted twin-feed spiral type fluorescent tube, so under the condition of same pipe range, can dwindle the volume of fluorescent tube, is convenient to install, use.

Four, description of drawings

Fig. 1 is a structural representation of the present utility model:

(1) is that oxide coated cathode, (3) are main amalgam for stem stem, (7) for exhaust tubule, (8) for seal wire, (6) for fluorescent coating, (5) for a pair amalgam, (4) (3a) for helical type lamp, (2) (1a) among the figure.

Fig. 2 is that the utility model is paid amalgam arrangement partial enlarged drawing:

(2) are that oxide coated cathode, (3) (3a) are stem stem for a pair amalgam, (5) for seal wire, (6) among the figure.

Claims (1)

1, the utility model has helical type lamp (1) (1a), oxide coated cathode (2), pay amalgam (3) (3a), fluorescent coating (4), seal wire (5), stem stem (6), exhaust tubule (7), main amalgam compositions such as (8), it is characterized in that fluorescent tube (1) is (1a) all by equidirectional rotation, form twin-feed spiral, helical type lamp (1) other end connection (1a) communicates, fluorescent tube (a 1) end (1a) respectively is equipped with oxide coated cathode (2), paying amalgam (3) for two (3a) is separately fixed on two seal wires (5) at oxide coated cathode two ends, oxide coated cathode (2) links to each other with seal wire (5), exhaust tubule (7) one end and main amalgam (8) join, and the other end places in the stem stem (6).
