Description

Traffic signal special-purpose non-filament gas discharge lamp

The invention belongs to lighting, be used for road traffic signal lamp.

Before the present invention, what traffic lights used is common tungsten lamp bubble, and there is following problems in it:

1, because the not stall of traffic lights signal is changed, reach every day hundreds of times, rush of current repeatedly makes filament accelerated ageing and evaporation, adds reasons such as vibrations, and bulb service life is extremely short, the frequent replacing of having to.

2, tungsten filament type incandescent lamp power consumption is big, and effectively brightness is low, the standing charges height.

3, every signal lamp is single bulb and does not have backup, in case lamp is spoilt, " blind lamp " just occur, often causes the unmanned commander's of traffic disordered state.

The purpose of this invention is to provide a kind of energy-conservation, long-life, no filament special gas discharge lamp, to overcome the drawback of above-mentioned original incandescent lamp.

The object of the present invention is achieved like this:

A kind of traffic signal special-purpose non-filament gas discharge lamp is made up of fluorescent tube, electrode, support, it is characterized in that: by paired non-filament gas discharge type fluorescent tube, and tube stand, carrier base, the boost injection-moulded housing and two covers, three electrodes of electronic circuit of built-in rectification are formed; The lamp tube ends head inserts the support upper end with both positive and negative polarity and light electrode and is connected, the jack of support lower end insertion carrier base, and carrier base is clamped on the horn mouth of housing again; Described lamp tube ends outer wall is the conducting metal positive and negative electrode, the conductive coating that the outer wall that fluorescent tube closes on an end points scribbles annular and is coated with bar shaped along lamp tube wall is as lighting electrode, the corresponding output of the electronic circuit that boosts of three kinds of electrodes of two covers connects, and shell end screw thread socket is connected with mains supply; Paired two fluorescent tubes, a job, another backs up, and the backup pipe is automaticallyed switch by electronic circuit and replaces the work fluorescent tube of damage.

In conjunction with the accompanying drawings, further specify content of the present invention.

Fig. 1 is contour structures front view of the present invention. In the prerequisite that does not change existing traffic lights profile and incandescent lamp socket Lower, change non-filament gas discharge type lamp into. The present invention is by non-filament gas discharge type fluorescent tube 1, electrode 7, and support 2, Carrier base 3, the injection-moulded housing 6 of the built-in electronic circuit board that boosts and original incandescent lamp socket 5 and 4 form. Two of fluorescent tube 1 Support 2 is inserted in the termination, and support 2 inserts the carrier base 3 (seeing Fig. 3, Fig. 4) with jack again, and carrier base 3 is twisted threadably Tightly in the horn mouth upper end of housing 6, housing 6 lower ends are original incandescent lamp socket 4 and 5, have on the gas discharge type fluorescent tube 1 Three electrodes 7, i.e. positive electrode, negative electrode and igniter electrode (shown in the dotted line). The electricity that boosts in three electrodes 7 and the housing 6 The electronic circuit output connects, and the electronic circuit power supply that boosts is drawn civil power by the original incandescent lamp socket 4 and 5 of housing 6 lower ends Enter. Civil power through frequency conversion, boost, rise to 15000 volts by 220 volts after the rectification. Discharge gas is generally inert gas at lamp Manage the 1 outer protective cover that layer of transparent can be arranged. Housing is ABS plastic. In use, be integrated with injection-moulded housing 6, Socket 4.5 insertion commercial power socket with the original signal lamp get final product. Principle of luminosity is that gas is excited aura and is put under high-frequency and high-voltage Electroluminescence.

Fig. 2 is contour structures top view of the present invention. Horizontal two parallel pipes in central authorities are two identical gas-discharge lamps Pipe 1, the two ends of this pipe are supported by support 2. Fluorescent tube quartz glass manufacturing is filled with inert gas in the pipe usually. Fluorescent tube Two ends 11, the 12nd, conducting metal positive and negative electrode, outer wall 13 scribble annular and bar shaped conductiving metal coating, are igniter electrodes. Three electrodes are connected with the electronic circuit output that frequency conversion is boosted. Igniter electrode is felt the visual perception when not having aura Lower to the high-frequency and high-voltage interruption, but total state of lighting that exists. After lighting normally, the both positive and negative polarity of lamp tube ends plays work With. Two fluorescent tube designs are that the another fluorescent tube is lighted use automatically by electronic circuit for when a fluorescent tube damages.

Fig. 3 is support front view of the present invention. Upper figure below is respectively positive and negative two, and the profile symmetry adds to put into earlier and leads man-hour Electric metal line and reed are again to namely becoming a complete support by bonding. Figure below half support has the groove of energising polar curve. Metal spring leaf be lamp tube ends positive and negative electrode 21,22 and coating be to light electrode, point be welded on this three lead respectively 71,72 and 73.

Projection 20 is orientation lock, in order to distinguish positive and negative electrode, plays the reinforcement effect at mechanics simultaneously. Both sides are prominent Play the 23, the 24th, positioning bar. When being used for support insertion carrier base 3, the two location.

Fig. 4 is carrier base 3 vertical views of the present invention.Horizontal in central authorities' a pair of socket that is being arranged in parallel, this socket is corresponding with support 2 lower end plugs 24,25.The jack of 3 electrodes, 71,72,73 lead-in wires is arranged in the middle of the socket, and mesopore is to light the contact conductor jack, about be respectively the positive and negative electrode wire jack.Both sides black partly is the jack of both sides, support 2 lower end plug 24,25.Carrier base 3 is clamped on the horn mouth upper end (see figure 1) of housing 6 in the bayonet socket mode.

This advantage:

1, compare with incandescent light bulb, power consumption is low, and under equal luminous intensity, power consumption only is 1/10th of incandescent lamp.

2, the life-span long, adopt no filament gas fluorescent tube, the life-span exceeds so that gas is aging, reaches more than 15000 hours, is about 25 times of existing homemade incandescent lamp bulb, more than 6 times of import incandescent lamp bulb.

3, a pair of fluorescent tube, wherein one is backed up, and when instrumentation tubes was damaged, electronic circuit can be lighted another immediately automatically, to solve " blind lamp " problem.

Embodiment

Durable energy saving type traffic lights, model are the TX10-120 type, 10 watts of power consumptions, and its brightness is equivalent to 120 watts of former incandescent lamp bulbs, can economize on electricity more than 90%.
