CN2521748Y - Double amalgam double-screw fluorescent lamp - Google Patents

Abstract

The utility model relates to a double-amalgam and a double-helix fluorescence lamp, which is double-helix shape and a lamp tube of which uses the amalgam. Helixes are formed at both ends of the lamp tube in the way of rotating in the same direction. Both ends of the lamp tube are equipped with the amalgam, while auxiliary amalgam is fixed on wires at two ends of two groups of cathodes. The lamp tube is provided with two pieces of main amalgam and four pieces of auxiliary amalgam. The wires are fixed on a core column, which is arranged in the lamp tube by being tangentially parallel with the helix direction and being coaxial with the helixes. After the wires are led out, the wires are connected with a pedestal of the lamp tube. Thus, the utility model is characterized in that the utility model is concise in the structure, the lamp tube startup time is short, the luminous flux establishment is quick, the use and installation is convenient, and the utility model causes little environmental pollution.

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, and according to the size of power, fluorescent tube need have certain length, existing generally use be yi word pattern, the fluorescent tube of U type, double-U-shaped, three U types had increased single-screw fluorescent tube and double helix pin fluorescent tube afterwards again.At the two ends of this helical lampl pin straight down, but adopt 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:

1, the utility model has seal wire (1) (1a), main amalgam (2), exhaust tubule (3), stem stem (4), pay amalgam (5) (5a), oxide coated cathode (6), helical type lamp (7) is the composition such as grade (7a), it is characterized in that fluorescent tube (7) is (7a) all by equidirectional rotation, form twin-feed spiral, helical type lamp (7) other end connection (7a) communicates, fluorescent tube (a 7) end (7a) respectively is equipped with oxide coated cathode (6), two pay two seal wires (1) that amalgam (5) (5a) is separately fixed at the oxide coated cathode two ends (1a) on, oxide coated cathode links to each other with seal wire, exhaust tubule (3) one end and main amalgam (2) join, the other end places in the stem stem (4), seal wire (1) (1a) is fixed on the stem stem (4), stem stem (4) and the tangential parallel coaxial of the hand of spiral place fluorescent tube (7) (7a) in, seal wire (1) (1a) is drawn the back and directly is connected with header.

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, and the exit of seal wire is tangentially parallel with the hand of spiral, directly links to each other with header.Make 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.
