Description

A kind of novel high-pressure sodium vapor lamp

Technical field

The utility model belongs to gas-discharge lamp, more particularly to a kind of high-pressure sodium lamp.

Background technology

High-pressure sodium lamp is one kind of gas-discharge lamp, and when use sends out golden white light, have luminous efficiency height, little power consumption, The advantages that long lifespan, mist transmitting performance are strong and do not lure worm.Be widely used in road, highway, airport, harbour, dock, station, Square, street intersection, industrial and mining enterprises, park, garden illumination and plant culture.

After light bulb starts, electric arc is generated between electric arc tube two end electrodes, the sodium in pipe is made due to the high temperature action of electric arc The heated evaporation of amalgam becomes mercury vapour and sodium vapor, and the electronics of emission of cathode hits discharging substance during to anode movement Atom, make its obtain energy production ionization or excitation, stable state is then returned to by excitation state；Or become exciting from state of ionization State returns ground state Infinite Cyclic, and extra energy is discharged in the form of light radiation, just produces light.

High-pressure sodium lamp has many good qualities, but its colour rendering is poor, in order to improve the illumination performances such as colour rendering, light efficiency, needs Increase the caliber of electric arc tube and uses higher internal gas pressure.But higher internal gas pressure needs the point of bigger Pulse is fired to light the gas-discharge lamp.Therefore, as the illuminating equipment component of device for igniting, socket or the like must be able to take this A larger firing pulse.A kind of mode for solving the problems, such as this is to reduce the firing pulse of highpressure sodium vapor discharge lamp.Therefore, The distance between electrode can be reduced or assistant piece is lighted in use, wherein tactile line is often the method for selection.

Traditional tactile line is that metal wire is coated on light bulb, when starting the lamp, the electric field action of complexed metal coil, in lamp The tip of the metal needle of gas chamber, which synchronizes, carries out effective electron emission, to generate light, and the light of generation is made to be efficiently entering light bulb Discharge space, to achieve the effect that promote light bulb start.Metal wire on traditional highpressure sodium vapor discharge lamp is " work " Font.It has the following problems：Cold junction temperature is low, and to influence colour rendering, cold junction temperature is unstable, and guiding discharge is unstable, light bulb Luminous flux, operating voltage, operating current and power be also at unstable working state, illumination performance is affected, simultaneously also It is difficult to have the shortcomings that start.

Invention content

1, technical problem to be solved：

Traditional highpressure sodium vapor discharge lamp, cold junction temperature is low, and to influence colour rendering, cold junction temperature is unstable, causes Discharge instability, luminous flux, operating voltage, operating current and the power of light bulb are also at unstable working state, illumination performance It is affected, while there is also start the shortcomings of difficult.

2, technical solution：

In order to solve problem above, the utility model provides a kind of high-pressure sodium lamp, including outer tube and inner tube, inner tube setting In outer tube, it is characterised in that：It is coated on the outer wall of said inner tube and touches line 1, the tactile line 1 includes two longitudinal metal coils 11 and a horizontal wire 12, one end of the horizontal wire 12 connects one of longitudinal metal coil 11, another The end of inner tube is held across another longitudinal metal coil 11 and extends to, the inner pipe end wraps up one layer of metal skin 2.

The metal skin 2 is connected by metal wire 3 with the niobium pipe of adjacent end portion.

The metal skin 2 is niobium skin.

3, advantageous effect：

The utility model is that conventional I-shaped metal wire is extended to end, and last layer metal is wrapped up in simultaneously in porcelain tube end It is connected on niobium pipe, improving cold junction temperature improves colour rendering, while cold junction temperature being made to keep stablizing, and electric discharge just tends to stablize, light bulb Luminous flux, operating voltage, operating current and power be also at steady-working state, reach improve illumination performance, help start Purpose.

Description of the drawings

Fig. 1 is the structural schematic diagram of the utility model.

Specific implementation mode

The utility model is described in detail below by attached drawing.

As shown in Figure 1, utility model provides a kind of high-pressure sodium lamp, including outer tube and inner tube, inner tube is arranged in outer tube, It is characterized in that：It is coated on the outer wall of said inner tube and touches line 1, the tactile line 1 includes two longitudinal metal coils 11 and one One end of horizontal wire 12, the horizontal wire 12 connects one of longitudinal metal coil 11, and the other end passes through another One longitudinal metal coil 11 and the end for extending to inner tube, the inner pipe end wrap up one layer of metal skin 2.

The metal skin 2 plays insulation effect, and the temperature of cold end is made to keep constant, in the feelings that cold junction temperature is kept constant Under condition, electric discharge just tends to stablize, and luminous flux, operating voltage, operating current and the power of light bulb are also at steady-working state, reach To the effect for improving illumination performance.

For better effect, the metal skin 2 is connected by metal wire 3 with the niobium pipe of adjacent end portion.Such structure, Metal skin 2 is directly connected with niobium pipe, makes the startup of high-pressure sodium lamp faster.

For better heat insulation effect and startup faster, metal select niobium.

Embodiment more than original text is only to illustrate the technological thought of the utility model, cannot limit the utility model with this Protection domain, it is every according to the utility model proposes technological thought, any change done on the basis of technical solution falls Enter within scope of protection of the utility model.The technology that the utility model is not directed to can be realized by existing technology.
