Description

Traffic signals special 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, traffic signals 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 signals special gas discharge lamp is characterized in that comprising fluorescent tube, tube stand, carrier base and housing;

Described fluorescent tube is two, and every tubes is the quartz glass tube of an inflation, at the two ends of every fluorescent tube the conductive metal layer sparking electrode is arranged, and ring-type is arranged on fluorescent tube one end outer wall and light electrode along the strip conductive metal layer of fluorescent tube;

The upper end of described every tubes support has pair of discharge electrodes and one to light electrode, and there are direction lock, location lock and support plug in the lower end;

Described carrier base is an insulator;

There is the thread head that is electrically connected with the city lower end of described housing, and two cover electronic circuits are arranged in housing, and electronic circuit plays rectification, frequency conversion and boosting;

Fluorescent tube snaps in tube stand, makes the positive and negative electrode of fluorescent tube and lights the respective electrode that electrode connects support respectively, and tube stand inserts carrier base, connects three output points of electronic circuit respectively.

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 the gas discharge type lamp into. The present invention is by gas discharge type fluorescent tube 1, electrode 7, and support 2, carrier base 3, built-in The boost injection-moulded housing 6 of electronic circuit board and original incandescent lamp socket 5 and 4 forms. The two ends of fluorescent tube 1 is inserted support 2, Support 2 inserts the carrier base 3 (seeing Fig. 3, Fig. 4) with jack again, and carrier base 3 is tightened in the loudspeaker of housing 6 threadably On mouthful, housing 6 lower ends are original incandescent lamp socket 4 and 5, three electrodes 7 are arranged, namely just on the gas discharge type fluorescent tube 1 Electrode, negative electrode and igniter electrode (shown in the dotted line), sparking electrode are exactly positive electrode and negative electrode. Three electrodes 7 and shell The electronic circuit output that boosts in the body 6 connects, and the original incandescent lamp socket of electronic circuit power supply by housing 6 lower ends boosts 4 and 5 introduce civil power. Civil power through frequency conversion, boost, rise to 15000 volts by 220 volts after the rectification. Discharge gas is common For inert gas at the fluorescent tube 1 outer protective cover that layer of transparent can be arranged. Housing is ABS plastic. In use, with injection moulding Housing 6 is integrated, and uses the socket 4.5 insertion commercial power socket of original signal lamp to get final product. Principle of luminosity is that gas is at high-frequency and high-voltage It is luminous to be excited down glow discharge.

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 lock. When being used for support insertion carrier base 3, the two location.

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

This advantage:

1, compare with incandescent light bulb, power consumption is low, under equal luminous intensity, power consumption only be ten of incandescent lamp/ One.

2, the life-span long, adopt the gas fluorescent tube, the life-span is limited so that gas is aging, reaches more than 15000 hours, is about existing 25 times of domestic incandescent lamp bulb, more than 6 times of import incandescent lamp bulb are arranged.

3, a pair of fluorescent tube, wherein one is backed up, and when instrumentation tubes was damaged, electronic circuit can be lighted other immediately automatically One, 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%.
