Description

Technical Field

[0001] The utility model belongs to the technical field of lighting, and particularly relates to a high-pressure sodium lamp with a neon bulb starting switch. Background Art

[0002] A high-pressure sodium lamp is a gas discharge lamp. The discharge tube is filled with working gas. The higher the working gas pressure, the better the plant lighting effect of the lamp. At the same time, a higher high-voltage pulse is also required to light it. For example, as described in application number ZL201610926164.6, a starting switch is required to light the high-pressure sodium lamp.

[0003] In order to overcome the problem that high-pressure sodium lamps require a higher starting voltage, while also taking into account the service life and stability of high-pressure sodium lamps, in addition to electromagnetic induction switches and temperature control switches, other modes of starting switch modes can also be used to increase the richness of the product and facilitate the use of different high-pressure sodium lamps in different environments. Utility Model Content

[0004] In order to solve the technical problems in the background technology that high pressure sodium lamps need high pulse voltage to light up and need to take into account stability and service life, the purpose of the utility model is to provide a high pressure sodium lamp with a neon bulb starting switch, which can solve the above technical problems.

[0005] The technical solution for achieving the purpose of the utility model is: a high-pressure sodium lamp with a neon bulb starting switch, comprising a neon bulb, a shell and an arc tube arranged in the shell, a metal wire is provided on the surface of the arc tube, and conductive brackets are respectively connected to the two ends of the arc tube, the first end of the neon bulb is connected to the metal wire at the first end of the arc tube, and the second end of the neon bulb is connected to the conductive bracket at the first end of the arc tube.

[0006] In this solution, the characteristics of the neon bulb are used as a starting switch. Specifically, because the neon bulb is filled with neon gas, the starting voltage only needs 90V-140V, so compared with the sodium lamp, the neon bulb is easier to conduct and light up after starting. After the neon bulb is lit, the trigger voltage passes through the neon bulb and then to the metal wire on the arc tube to generate high voltage, so that an arc is started in the arc tube, the metal wire is turned on, and the sodium lamp is lit. After lighting, the arc tube is completely turned on, that is, the metal wire establishes a direct discharge arc, and a high-voltage trigger voltage is no longer required; because the neon bulb is not directly connected to the lighting appliance that provides high voltage, the neon bulb will not light up after it goes out, that is, it will no longer work; in this way, by adding the neon bulb, the lighting of the high-pressure sodium lamp is ensured, and the neon bulb can also stop working after the sodium lamp is lit, which has high stability and a long service life.

[0007] Furthermore, a metal wrapping belt connected to the metal wire is provided on the first end of the arc tube, and the neon bulb is connected to the metal wire through the metal wrapping belt. When the circuit is connected, the neon bulb superimposes the energy obtained on the metal wire in the arc tube through the metal wrapping belt, helping the metal wire to reach a high temperature earlier and light up the high pressure sodium lamp.

[0008] Furthermore, the neon bulb is fixed on the metal wrapping belt and is closer to the metal wrapping belt, so that the energy of the neon bulb can reach the metal wire as quickly as possible, thereby lighting the sodium lamp.

[0009] Furthermore, a fixing bracket is fixed on the conductive bracket, and the neon bulb is fixed on the fixing bracket, so the fixing effect is good and more stable.

[0010] Furthermore, the first end of the arc tube (3) is connected to the electrode portion (14), the conductive bracket (5) and one leg (7) of the neon bulb, and the other end is connected to another conductive bracket and an electrical appliance. If the neon bulb is connected to the end of the electrode portion, when the lamp is lit, the trigger voltage provided by the lighting electrical appliance passes through the neon bulb and is then transmitted to the metal wire to generate high voltage, and the sodium lamp is lit.

[0011] Furthermore, a sealing plate is provided at both ends of the shell, a molybdenum sheet conductive sheet is provided inside the sealing plate, and the conductive bracket is connected to the molybdenum sheet conductive sheet, which facilitates the conduction of the circuit and increases the internal structural space for the arrangement of various components in the end.

[0012] Furthermore, the high pressure sodium lamp is a single-ended lamp or a double-ended lamp, which can be flexibly set and freely selected for different lamps and lamp holders and different applicable environments, thereby increasing the versatility of the high pressure sodium lamp.

[0013] Furthermore, the shell is made of hard glass material, such as quartz glass, to avoid the problem of easy damage.

[0014] Furthermore, the high pressure sodium lamp is equipped with a lighting appliance, which provides a normal starting trigger voltage and working circuit for the high pressure sodium lamp and maintains the normal operation of the lamp. The lighting appliance can provide a high trigger voltage, which is distributed to both ends of the arc tube and the neon bulb, which is sufficient to ensure the smooth lighting of the high pressure sodium lamp.

[0015] Furthermore, a bracket is provided in the outer shell, one end of the bracket is connected to the second end of the arc tube, the other end of the bracket is connected to the support leg of the inner core column of the lamp holder, and the first end of the arc tube is connected to the other support leg of the inner core column of the lamp holder through a conductive bracket; a getter is fixed on the bracket.

[0016] By adopting the above technical solution, the utility model has the following beneficial effects:

[0017] (1) Taking advantage of the fact that neon bulbs are easy to light up, the energy is then transferred to the metal wire. After the high voltage is generated on the metal wire, it is turned on, and the high-pressure sodium lamp can be lit smoothly, with good stability and long service life;

[0018] (2) The neon bulb is connected to the metal wire through the metal wrapping tape, and when the line is connected, energy is superimposed on the metal wire through the metal wrapping tape;

[0019] (3) The neon bulb can be fixed in a flexible manner. It can be fixed between the metal wrapping belt and the conductive bracket by two electrodes, or fixed on the metal wrapping belt, or fixed on the conductive bracket by the fixing bracket;

[0020] (4) High-pressure sodium lamps can be either single-ended or double-ended, and can be freely selected according to environmental needs, with greater functionality. BRIEF DESCRIPTION OF THE DRAWINGS
