CN2935707Y - Sodium light bulb with starter mechanism - Google Patents

Abstract

The utility model relates to a sodium lamp bulb with a starting mechanism, which is mainly connected in parallel with a starting mechanism inside the sodium lamp bulb so that it can be directly used in a general lamp holder. After conducting electricity, the action of the bouncing metal sheet of the starting mechanism generates an instantaneous pulse voltage, which can achieve the start-up and lighting of the sodium lamp and obtain practical effects.

Description

Sodium light bulb with starter mechanism

technical field

The utility model relates to a sodium lamp bulb, in particular to a sodium lamp bulb with a starting mechanism.

Background technique

Generally, in order to obtain high-brightness lighting effects, bulbs such as mercury lamps or sodium lamps are mainly used to provide better lighting, and are suitable for roads, stadiums or other places that require high brightness. The starting voltage of the existing mercury lamp bulb is relatively low, and it can be directly used and fitted on a general lamp holder provided with a mercury lamp ballast. However, if you want to use the sodium lamp bulb 1, as shown in Figure 1, because the required start-up voltage of the existing sodium lamp bulb is relatively high, the current method usually uses different types of designs to combine a pulse voltage generator in the In the lamp holder, a combination of the existing sodium lamp bulbs 1 is provided. When conducting electricity, a momentary voltage is generated in the lamp holder to light the sodium lamp bulb for the purpose of lighting. However, in the current structure, the lamp holder for the sodium lamp bulb is different from the general existing lamp holder, and a special ballast must be installed for the sodium lamp. Therefore, it is quite inconvenient to use and has no obvious appearance Distinction, often causing confusion.

Contents of the invention

The purpose of this utility model is to provide a sodium lamp bulb that can be used conveniently and directly, which can be combined with a general lamp holder to emit light, and the lamp holder does not need to be refitted to achieve the purpose of convenient use.

For realizing above-mentioned object, the technical scheme that the utility model adopts is:

A sodium lamp bulb with a starting mechanism, which has a conductive rod and a lamp tube inside the bulb, and is characterized in that a parallel starting mechanism is arranged inside the bulb, one end of which is connected to the conductive rod, and the other end is connected to the lamp tube. The starting mechanism has two contact plates, and a bouncing metal sheet is arranged between them, and the bouncing metal sheet is electrically connected to the two contact plates at normal temperature, and deforms when the temperature rises and disconnects its electrical connection with the contact plate .

Compared with the prior art, the utility model has the advantage that it can be combined with a general lamp holder to emit light, and the lamp holder does not need to be refitted, which is convenient for use.

Detailed ways

Please refer to Fig. 2 to Fig. 5, the utility model is mainly to add a parallel starting mechanism 3 in the sodium lamp bulb 2, so that one end is connected to the lamp tube 21, and the other end is connected to the conductive rod 22 to start the The mechanism 3 has two contact plates 31, 32, and a bouncing metal piece 33 is arranged between them, and the angle of the metal piece 33 can change due to temperature.

When no power is supplied, the lamp tube 21 in the sodium lamp bulb 2 does not emit light, and the bouncing metal sheet 33 is in contact with the contact plate 31 on one side as shown in FIG. 2 and FIG. 4 . After the power is turned on, the metal sheet 33 is heated under the power circuit, so that its own temperature rises rapidly, and at a certain temperature, it jumps away from the contact plate 31, forming the contact plate 31 as shown in Figure 3 and Figure 5. When the circuit is disconnected, the circuit formed by the lamp tube 21 and the metal rod 22 generates a pulse voltage at this time, which can make the lamp tube 21 light up and emit light, thereby providing the lighting effect.

In summary, the sodium lamp bulb provided by the utility model has a starting mechanism inside the body, so it does not need to cooperate with a special lamp holder structure for sodium lamps. For use in lampholders having mercury lamp ballasts, without distinction from the use of mercury lamps.

The above description is only illustrative of the present utility model, rather than restrictive. Those of ordinary skill in the art understand that many modifications, changes, or equivalent, but all will fall within the scope of the claims of the present utility model.
