Abstract
The utility model relates to the technical field of sodium lamps, and particularly relates to a high-voltage sodium lamp, which comprises a glass shell; an electric arc tube and a starting device are in sealed arrangement inside the glass shell; electrodes are arranged at the two ends of the electric arc tube; the starting device is in parallel connection with the two ends of the electric arc tube; electrical connectors are arranged on the outer sides of the two ends of the glass shell; and the electrodes at the two ends of the electric arc tube are electrically connected with the electrical connectors corresponding to the electrodes through lead wires. The structure reveals that the electrodes at the two ends of the electric arc tube are led out of the two ends of the glass shell through the lead wires and are electrically connected with the electrical connectors to form a dual-head high-voltage sodium lamp, so that the utility model can horizontally mounted in the reflecting shade of the lamp; when rays are emitted by the electric arc tube, half of rays can be directly irradiated out for lighting, and the other half of rays only needs to be reflected by the reflecting shade of the lamp. Therefore, compared with the high-voltage sodium lamp adopting a spiral lamp cap, the utility model can improve the utilization rate of the rays emitted by the lamp.
Description
Technical field:
The utility model relates to the sodium vapor lamp technical field, relates in particular to a kind of high-pressure sodium lamp.
Background technology:
Luminous efficiency height, little power consumption, life-span are long because high-pressure sodium lamp has, mist transmitting performance lures advantages such as worm by force and not, and it is widely used on the lighting in places such as road, square, street.At present, be applied in the high-pressure sodium lamp on the light fixtures such as street lamp, it mainly comprises lamp screw base, glass bulb, lamp screw base is fixed on an end of glass bulb, the other end sealing of glass bulb, the inner sealing of glass bulb is provided with electric arc tube, is filled with inert gas in the electric arc tube, the two ends of electric arc tube are provided with electrode, and the two ends of electric arc tube are parallel with starting drive, after starting drive starts electric arc tube, produce electric arc between the electrode at electric arc tube two ends, make electric arc tube produce light, be used for illumination; The high-pressure sodium lamp of this employing lamp screw base, it generally is the center that vertically is installed in light fitting reflecting cover, the light that can make the electric arc tube generation like this, it or not directly irradiation downwards, but most light all needs the reflection of light fitting reflecting cover, irradiation downwards produces illuminating effect, because the influence of reflectivity, this will inevitably reduce the light utilization of light fixture; And, because there is problem loosening easily, that damage easily when installing in lamp screw base, adopt the high-pressure sodium lamp of lamp screw base, its fastness that installs and fixes is also relatively poor, especially in the transportation of light fixture, adopt the high-pressure sodium lamp of lamp screw base often to cause ease of connection loosening, cause problems such as loose contact.
The utility model content:
The purpose of this utility model is exactly to provide a kind of high-pressure sodium lamp that can improve the light utilization of light fixture at the deficiency of prior art existence.
To achieve these goals, the technical solution adopted in the utility model is:
It comprises glass bulb, the inner sealing of glass bulb is provided with electric arc tube, starting drive, the two ends of electric arc tube are provided with electrode, starting drive is in parallel with the two ends of electric arc tube, the outside at described glass bulb two ends is equipped with electrical connector, and the electrode at electric arc tube two ends is electrically connected with corresponding electrical connector respectively by lead-in wire.
The two ends of described glass bulb are provided with the enclosed area, and the enclosed area internal fixation has conducting strip, and an end of conducting strip is connected with electrical connector, and the other end is connected with the lead-in wire of electrode.
Described electrical connector comprises insulated terminal, lead, and insulated terminal is fixed on the outside of enclosed area, and insulated terminal is provided with the position, hole, and lead passes the position, hole of insulated terminal, extend in the enclosed area to be connected with conducting strip.
Be connected with stator on the described lead.
The utility model beneficial effect is:
A kind of high-pressure sodium lamp that the utility model provides comprises glass bulb, the inner sealing of glass bulb is provided with electric arc tube, starting drive, the two ends of electric arc tube are provided with electrode, starting drive is in parallel with the two ends of electric arc tube, the outside at described glass bulb two ends is equipped with electrical connector, and the electrode at electric arc tube two ends is electrically connected with corresponding electrical connector respectively by lead-in wire; By said structure as can be seen, the electrode at electric arc tube of the present utility model two ends is to draw from the two ends of glass bulb by lead-in wire, be electrically connected with electrical connector, thereby formed the high-pressure sodium lamp of bullhead, make the utility model flatly to be installed in the light fitting reflecting cover, when electric arc tube produced light, the light of half can be gone out by direct irradiation, be used for illumination, have only second half light to need the reflection of light fitting reflecting cover; Therefore, compare with the high-pressure sodium lamp that adopts lamp screw base, the utility model can improve the light utilization of light fixture.
Description of drawings:
Fig. 1 is a structural representation of the present utility model
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described, please refer to Fig. 1, the utility model comprises glass bulb 1, the inner sealing of glass bulb 1 is provided with electric arc tube 2, starting drive 3, the two ends of electric arc tube 2 are provided with electrode 4, starting drive 3 is in parallel with the two ends of electric arc tube 2, the outside at described glass bulb 1 two ends is equipped with electrical connector, the electrode 4 at electric arc tube 2 two ends is electrically connected with corresponding electrical connector respectively by lead-in wire 5, more particularly, the two ends of described glass bulb 1 are provided with enclosed area 6, and enclosed area 6 internal fixation have conducting strip 7, one end of conducting strip 7 is connected with electrical connector, and the other end is connected with the lead-in wire 5 of electrode 4.
The electrical connector of present embodiment comprises insulated terminal 81, lead 82, and insulated terminal 81 is fixed on the outside of enclosed area 6, and in being installed in light fixture, this insulated terminal 81 can be used to connect and fix the two ends of high-pressure sodium lamp; Described insulated terminal 81 is provided with the position, hole, one end of lead 82 passes the position, hole of insulated terminal 81, extend in the enclosed area 6 and be connected with conducting strip 7, the other end of lead 82 is connected with stator 9, this stator 9 is connected with the power output end of light fixture, like this, make that the electrode 4 at electric arc tube 2 two ends can be successively by lead-in wire 5, conducting strip 7, lead 82, stator 9 is electrically connected with the power output end of light fixture, compare with the high-pressure sodium lamp that adopts lamp screw base, fixed structure of the present utility model (being the insulated terminal 81 at two ends) separates with power connection structure, after can making the utility model be fixed in the light fixture, more firm, be difficult for becoming flexible, can not produce problems such as loose contact.
