Abstract

The utility model relates to a fluorescent lamp with a long service life (bulb with bayonets) and sockets (lamp openings) thereof. The utility model is characterized in that both ends (the inner side of the bulb) of the lamp are respectively additionally provided with a lamp filament and two plugs (A lamp cap is additionally with two soldering tin points.). The lamp is matched with the two four hole sockets, wherein, two holes are connected with wires, and other two holes are hollow holes. (The circumference of a clamping ring of the lamp opening of the bulb is evenly provided with four bayonets.) Therefore, one group of lamp filaments are used for installation every time, and the other group of lamp filaments are in the ready state for use because the other group of lamp filaments are inserted in the hollow holes. (The lamp cap of the bulb is only provided with two clamping rods, so that only the two bayonets of the lamp opening are used every time, and the other two are in the ready state for use.) When one group of lamp filaments is broken, the broken lamp filaments are dismounted and moved 90 DEG, the other group of the lamp filaments is installed. Therefore, the service life of the lamp (the bulb) can be effectively extended by twice.

Description

Longlife light bulb tube with double filaments and bayonet bulb

The utility model relates to a kind of power lighting fluorescent tube, extraordinary fluorescent tube and bayonet-type bulb, and for the socket and the socket of its use.

Existing power fluorescent light pipe is with bayonet-type bulb and be used for industry, agricultural, medical treatment, the fluorescent tube and the bayonet-type bulb of special trade such as communicate by letter.It comprises glass lamp and cell-shell, the inside charges into desired gas, a coiled-coil filament that is enclosed in pipe (two ends), the bubble is welded on two filament supports, two electrode plugs and two bumps of communicating pipe, the outer lamp holder of bubble, they pass through separately socket and socket and other pieces composition loop, and energising is lighted the filament heating.Because filament has only one, through switch repeatedly, rush of current filament, the filament evaporation is attenuated in this fluorescent tube (two ends), the bubble, resistance increases, and filament has just burnt in use for some time.With the fluorescent light pipe is example: data record average life span only is 2000-3000 hour, every switch once just shortens life-span 1.5-2 hour, can reach 12000 hours as continuous use lamp tube service life, this shows that the burn-out life weak point is the main factor that fluorescent tube damages.Other is as the fluorescent material amount of being coated with, and the pressure of argon gas then is less important, and above data have proved absolutely this point.

The purpose of this utility model is to provide a kind of pair of filament long service life lamp tube, bulb, and it is the useful life of prolonging lamp tube, bulb effectively.

The utility model is achieved in that at glass lamp and cell-shell the inside and charges into desired gas.There is a coiled-coil filament to be welded on two filament supports, two electrode plugs and two bumps of support communicating pipe (two ends), the outer lamp holder of bubble, relevant position, lamp holder metal collar surface is provided with two card rods, is used for holding bulb.It is characterized in that having increased a coiled-coil filament again in fluorescent tube (two ends), bubble is welded on two filament supports newly establishing, two electrode plugs and two bumps that support communicating pipe (two ends), the outer lamp holder of bubble are newly established; Two groups of filament supports, one long a, weak point in pipe (two ends), the bubble, filament is orthogonal, and is separated by a distance; Also can two groups of filament supports equally long, in the middle of being parallel to each other, filament is separated with certain distance.Two groups of (four) electrode plugs and its line of bump of fluorescent tube (two ends), the outer lamp holder of bubble are orthogonal, and evenly the loop is formed in distribution separately.

A kind of socket for the fluorescent tube use, it is made by insulation and electric conducting material.On a cylindrical end face, two electrode jacks are arranged, draw the access external circuit from the jack other end with two wires.It is characterized in that increasing again on socket one end face two emptying apertures of diameter greater than two patch jacks, its line and former two hole lines are orthogonal.When one group of disintegration of filament point of energising use does not work, only need fluorescent tube is unloaded, rotate fluorescent tube 90 degree, two electrode plugs of the one group of filament that increases newly insert in original two electrode jacks, and fluorescent tube continues to light; Two electrode plugs of one group of filament lamp holder that fluorescent tube is bad withdraw from circuit, two emptying apertures that place socket to newly establish.

A kind of socket for the bayonet-type bulb use, it is made by insulation and electric conducting material.The socket front end have one with the metal collar that bulb is used that holds of current-carrying part insulation, a bayonet socket is respectively arranged about the circumference of its end face, the metal columns of two band springs are arranged in the socket, have two wires to connect and draw the access external circuit from the metal column other end.The end face circumference that it is characterized in that the metal collar has respectively increased a same bayonet socket up and down again.When one group of disintegration of filament point of energising does not work, only need bulb is unloaded rotation bulb 90 degree, two card rods of lamp holder snap in two bayonet sockets that increase newly.Bulb continues to light.One group of bad filament of bulb withdraws from circuit through two bumps, places socket internal pore place, has realized the exchange of two groups of filaments of bulb.Fluorescent tube is not owing to be directly luminous by filament, but is provided with less electric current heat filament by ballast moment, so filament is shorter, this technology is suitable fully.The interior filament of bulb is difficult for long, is suitable for low-voltage, low-power bulb, fluorescent tube, and fracture of wire overlaps switch on filament or filament support in the bubble, also can not influence its operate as normal.

Owing to the utlity model has at fluorescent tube (two ends), be provided with two groups of filaments in the bubble, when one group of damage, another group can work on, prolonged useful life one times of fluorescent tube, bubble effectively, though it is little to have solved filament, make whole fluorescent tube, finish good part and all scrap, cause the huge waste of lot of materials and manpower.

The concrete structure of utility model is provided by following examples and accompanying drawing thereof.
