Description
Technical field
The utility model relates to a kind of high-intensity gas discharge lamp fluorescent tube, especially relates to the two light source high-intensity gas discharge lamp fluorescent tubes of a kind of both-end.
Background technology
High-intensity gas discharge lamp (the High Intensity Discharge of main flow on the present market, be called for short HID) comprise that mainly high strength receives lamp and chromatic metallic halide lamp, have advantages such as power saving, superbright degree, colour temperature comfort level height, life-span length, installation safety, and be widely used in fields such as automobile industry, urban transportation illuminations.
High-intensity gas discharge lamp drives by Inductive ballast, use Inductive ballast to drive must to be used starter to come the assistant starting discharge lamp, and also there is excess loss power in Inductive ballast, be about with 25% of fluorescent tube nominal power.
Therefore, consider that high-intensity gas discharge lamp can drive by electric ballast,, then must not use starter if use electric ballast to drive from energy-conservation angle, excess power only be about with 5% of fluorescent tube nominal power.But, because the limitation of existing electric ballast technology itself, electric ballast supports the high-intensity gas discharge lamp fluorescent tube can stablize and reliably working the time, the maximum power of described high-intensity gas discharge lamp fluorescent tube can only be below 200W, this power with general urban transportation lighting requirement discharge lamp is that 250W or 400W are incompatible, does not obviously reach requirement.Therefore present most high-intensity gas discharge lamp fluorescent tube still is to use Inductive ballast to drive.
Simultaneously, general city generally adopts the mode of closed portion discharge lamp to come energy savings in the period at midnight, this has brought a lot of inconvenience at that time pedestrian or steering vehicle personnel by these highway sections, also is easy to cause traffic accident, thereby brings bad social influence.
The utility model content
Main purpose of the present utility model is to provide a kind of both-end two light source high-intensity gas discharge lamp fluorescent tubes, it can make high-intensity gas discharge lamp when reaching considerable energy-saving effect, do not influence of the normal illumination of period at midnight to traffic, minimizing because of midnight the closed portion discharge lamp to pedestrian and the inconvenience that causes of contact vehicle, thereby reduce the incidence of traffic accident.
For reaching above-mentioned purpose, the utility model provides a kind of both-end two light source high-intensity gas discharge lamp fluorescent tubes, and it comprises sealing two lamp holders of all-in-one-piece and a transparent glass tube;
Described two lamp holders are separately positioned on the two ends of transparent glass tube;
Be provided with electrode on the described lamp holder, comprise a common electrode shared with another lamp holder, and the independent absolute electrode that uses of this lamp holder;
Be provided with two luminous tubes in the described transparent glass tube, these two luminous tubes are corresponding respectively to be fixed on two lamp holders and the end that transparent glass tube is connected; One end of these two luminous tubes connects common electrode in the corresponding lamp holder by metal support, and the other end connects absolute electrode in the corresponding lamp holder by metal support, makes two luminous tubes connect into two light sources;
Described absolute electrode is connected with the control switch that ballast that starts luminous tube and control luminous tube open and close respectively.
Described two lamp holders are screw cap.
Described luminous tube is high strength sodium pipe or chromatic metallic halogenation property management.
Described luminous tube is separately fixed on the corresponding lamp holder by glass stem.
Described absolute electrode is a metal level, and it is arranged on the bottom outer surface of lamp holder, and and lamp holder between be provided with insulator, isolate with cap body.
Described common electrode is the metal level of a circle circle around the lamp holder outer surface, and this layer on surface of metal is shape in the shape of a spiral, can be in order to the fixed light head.
The startup ballast of the two light source high-intensity gas discharge lamp fluorescent tubes of both-end described in the utility model is an electric ballast.
The startup ballast of the two light source high-intensity gas discharge lamp fluorescent tubes of both-end described in the utility model is an Inductive ballast.
The two light source high-intensity gas discharge lamp fluorescent tubes of the both-end that the utility model provides, include two luminous tubes, it is respectively by ballast driven, thus, optionally closes certain luminous tube in the discharge lamp by control switch, only stay a luminous tube in running order, but still can make whole discharge lamp luminous, therefore, when fully reaching energy-conservation purpose, also can not influence the illumination of road traffic, can not bring inconvenience driver and pedestrian.
The two light source high-intensity gas discharge lamp fluorescent tubes of the both-end that the utility model provides, the ballast that starts luminous tube can be Inductive ballast, also can be electric ballast; When using electric ballast, each electric ballast power controlling respectively is the luminous tube of 125W or 200W, can support the work that this luminous tube is reliable and stable thus, simultaneously, because this discharge lamp fluorescent tube comprises the luminous tube of 2 serial connections, make the lighting power of whole discharge lamp can reach 250W or 400W, also meet the general requirement of urban transportation illumination, and because what use is electric ballast, then do not need to use starter, so excess power reduces greatly, only is about 5% of fluorescent tube nominal power, further realizes energy-saving effect.
Description of drawings
Fig. 1 is the structural representation of the two light source high-intensity gas discharge lamp fluorescent tubes of the both-end that provides of the utility model.
Embodiment
Below in conjunction with Fig. 1, describe the utility model preferred implementation in detail:
As shown in Figure 1, the two light source high-intensity gas discharge lamp fluorescent tubes of both-end provided by the utility model comprise two screw caps 10 and 12, one transparent glass tubes 11; Described two screw caps 10 and 12 are installed in the two ends of transparent glass tube 11 respectively; This transparent glass tube 11 vacuumizes, and its two ends and screw cap 10 and 12 are tightly connected and form a reception room;
Described screw cap 10 is provided with common electrode 14 and absolute electrode 15; Described screw cap 12 is provided with common electrode 14 and absolute electrode 16; This common electrode 14 is circle circle metal levels around screw cap 10 and 12 outer surfaces, and this layer on surface of metal is shape in the shape of a spiral, can be in order to fixing screw cap 10 and 12; Described absolute electrode 15 is a metal level, is arranged on the bottom outer surface of screw cap 10, and is provided with insulator 17 between this absolute electrode 15 and the screw cap 10, isolates with the main body of screw cap 10; Described absolute electrode 16 is a metal level, is arranged on the bottom outer surface of screw cap 12, and is provided with insulator 17 between this absolute electrode 16 and the screw cap 12, isolates with the main body of screw cap 12;
Be provided with two luminous tubes 110 and 113 in the described transparent glass tube 11, these two luminous tubes 110 and 113 are high strength sodium pipe or chromatic metallic halogenation property management; Luminous tube 110 is fixed on screw cap 10 and the end that transparent glass tube 11 is connected by glass stem 111 correspondences; One end of this luminous tube 110 is connected with common electrode 14 on being located at screw cap 10 by metal support 112, and the other end is connected with absolute electrode 15 on being located at screw cap 10 by metal support 112; Luminous tube 113 is fixed on screw cap 12 and the end that transparent glass tube 11 is connected by glass stem 111 correspondences; One end of this luminous tube 113 is connected with common electrode 14 on being located at screw cap 12 by metal support 112, and the other end is connected with absolute electrode 16 on being located at screw cap 12 by metal support 112; Form electric loop thus, make two luminous tubes 110 and 113 and be connected into two light sources;
