Abstract

PURPOSE:To obtain a new high-pressure discharge lamp small-sized and with high efficiency utilizing a high-frequency lighting method by connecting a luminous tube and an incandescent filament in parallel. CONSTITUTION:A housing 2 storing a lighting circuit contains a DC power supply section 3 consisting of a rectifier and a high-frequency inverter 4 inside, and the output of the inverter 4 is connected to a luminous tube 7 and an incandescent filament 8 stored in an outer tube 5 via connection terminals 6a, 6b. According to this connection, high voltage can be obtained across output terminals 6a-6b of the inverter 4 when the luminous tube 7 has high impedance at starting and restarting, thus facilitating the starting and restarting of the luminous tube 7. During the normal operation when the impedance of the luminous tube 7 reaches a rated value, the power used by the incandescent filament 8 becomes extremely small, almost all the power is consumed by the luminous tube 7, and the whole efficiency is improved. In addition, the lamp and lighting circuit are formed in one body and made compact.

Traditionally, incandescent light bulbs and fluorescent lamps have been the most popular light sources for indoor lighting. However, although incandescent light bulbs are cheap, their power-to-light conversion efficiency is as low as about 101 m/W, and they no longer meet today's demands for energy conservation. Furthermore, although high-efficiency fluorescent lamps with a power consumption of 90"7W have been announced in recent years, their use is limited to offices and the like because the lamps themselves and equipment are large. On the other hand, high-pressure discharge lamps such as high-pressure mercury lamps, metal halide lamps, and high-pressure sodium lamps can provide high output even if they are small, but when used with commercial power, they must use heavy ballasts with copper wire wrapped around the iron core. Moreover, it has the disadvantage that it does not restart immediately after the power is turned off, which has hindered its widespread use as a light source for indoor lighting. Furthermore, when lit with a commercial frequency AC power source, a flickering phenomenon called flicker is observed, and this tendency is more likely to occur as the device is made smaller, which is also a technical problem. On the other hand, if a discharge lamp is lit at a high frequency, the ballast becomes smaller and lighter and the problem of flicker can be solved, but this problem also poses a problem because an acoustic resonance phenomenon peculiar to high-frequency lighting occurs.

Various attempts have been made to solve these problems and provide a compact and highly efficient high pressure discharge lamp suitable as a light source for indoor lighting. For example, JP-A-56-3992
There is a high pressure discharge lamp as described in the above publication. This utilizes the principle of direct current lighting of the arc tube of a high-pressure discharge lamp via a resistive ballast consisting of an incandescent filament connected in series with it. A control circuit is provided to compensate for the lack of luminous flux of the discharge lamp using an incandescent filament at the time of starting or restarting. However, although such discharge lamps do not produce acoustic resonance original images because they are powered by direct current, special techniques must be used in the design and manufacturing process of the arc tube in order to obtain a long life as a light source for general illumination. In addition to high costs, the resistance ballast connected in series with the arc tube resulted in poor arc power utilization, resulting in low lamp efficiency. Furthermore, the lamp structure and control circuit were complex, making it difficult to achieve high reliability.

An example of oil is a high pressure discharge lamp as described in Japanese Patent Application Laid-open No. 58-30062. This system uses a transistor switch instead of an incandescent filament for the ballast, allowing the entire electronic circuit to power the lamp, thereby supplementing the light generated during starting and restarting. However, this discharge lamp has a complex circuit and many parts, and there are unresolved issues in terms of reliability and cost. On the other hand, research on high-frequency lighting systems using inverters is also being actively conducted, but so far there have been many difficulties in putting this into practical use in high-pressure discharge lamps. The reason for this is that the technology to avoid the acoustic resonance phenomenon mentioned above has not been established, and the basic circuit of the inverter is a two-stone push-pull inverter, which has become larger and costs have increased, making it less effective than expected. As a result, practical application was limited to fluorescent lamp lighting circuits.

The feature of the present invention is that the arc tube T and the incandescent filament 8 are connected in parallel, and the incandescent filament 8 does not act as a ballast for the arc tube T.

The current limiting function of the discharge lamp is included in the high frequency inverter 4. Further, the operating resistance value of the incandescent filament 8 must be selected to be somewhat larger than the operating impedance value of the arc tube I. For example, if the rated lamp voltage and run:j power of the arc tube 1 are 50 V and 50 W, respectively, the impedance value of the arc tube 7 during rated operation is about 500. On the other hand, the operating resistance value e of the incandescent filament 8
If 1000Ω is selected and the no-load open-circuit voltage of the inverter 4 is, for example, 200V, about 40W of power is applied to the incandescent filament 8, and a luminous flux of about 5001m can be obtained. Then, when the discharge lamp is lit and the impedance of the arc tube 7 decreases, the voltage of the incandescent filament 8 and hence the input power also decrease, and for example, when the impedance of the arc tube 7 reaches the rated value, it becomes 5 W or less.

The incandescent filament 8 is generally made of tungsten filament, and tungsten filament has a large positive temperature coefficient of resistance, and has a property that the resistance value decreases as the filament voltage decreases. In consideration of this point, in the connection shown in FIG. 1, it is necessary to select a filament resistance value that is large to a certain extent so that the filament power during stable operation does not become too large.

This is because during stable operation, it is possible to increase efficiency as a whole by inputting power to the arc tube side as much as possible.

Any type of high-frequency inverter may be used, but for those that use a transformer to extract the output voltage, the rated The power input to the filament during operation can be significantly reduced, increasing efficiency. Moreover, in this case, the degree of freedom in selecting the filament resistance value is increased. This method is advantageous for metal halide lamps and high-pressure sodium lamps whose arc tubes have a high starting voltage.

This configuration will be explained. When the base 1 is connected to the power line circuit, commercial power is input to the diode bridge 3a, and the rectified output is charged to the filter capacitor 3b to form a DC power source. This DC output is input to a transistor type high frequency inverter 4 constituted by an ER amplifier. This inverter 4 basically consists of a transistor 4c and a capacitor 4b.

It is composed of a choke coil 4a and an inductor 4d. In this circuit, a feedback winding a4f is provided in the inductor 4d, and the feedback winding a4f is returned to the base of the transistor via a resistor 4g, thereby making it self-excited. 4j is a starting resistance. The output of the inverter 4 is taken out to a discharge lamp load, ie, an arc tube 7, and a resistive load, ie, an incandescent filament 8.

The incandescent filament 8Fi may be connected in series with the arc tube 7 as shown in FIG. 1, but in this case it is inserted in parallel with the arc tube T via the capacitor 41. With this connection, when the arc tube T exhibits high impedance at the time of starting and restarting, a high voltage can be obtained between the output terminals (ia and fib) of the inverter 4, making it easier to start and restart the arc tube T. Moreover, at this time, the current flowing to the incandescent filament 8 is limited because it passes through the capacitor 41.
The resistance value of the incandescent filament 8 may be reduced. That is, there are fewer restrictions on the resistance value of the incandescent filament 8.

Furthermore, what is important about this configuration is that the power input to the incandescent filament 8 becomes extremely small during normal operation when the impedance of the arc tube 7 reaches its rated value.

The reason for this is that when the arc tube 7 is in rated operation, the output terminal 9
In addition to the low voltage of m-5b open, capacitor 4
Since the incandescent filament 8 is connected via i, the terminal voltage of the incandescent filament 8, that is, the output terminal (ic
This happens when the voltage between -6h becomes very small. Therefore, at this time, the input power to the incandescent filament 8 becomes negligible, and most of the power is consumed in the arc tube T, thereby increasing the overall efficiency.

In addition, this configuration overcomes the drawback of class E amplifiers, which is that they are susceptible to variations in load resistance. In other words, the amplifier is essentially inoperable, especially for discharge lamp loads where the load impedance is infinite before starting. However, according to this configuration, since the incandescent filament, which is a resistive load, is always connected to the output terminal with or without reactance, this problem can be solved. At the same time, the incandescent filament provides light when the discharge lamp is not in operation, thus solving the disadvantages inherent in discharge lamps. Furthermore, class E amplifiers have a conversion efficiency of 90 CH or higher even at high frequencies of the MHJ order.
The lighting frequency may be increased to l5QKH2 or higher,
This not only avoids acoustic resonance phenomena, but also has a simpler circuit than a conventional two-stone push-pull inverter, making it even more effective in reducing size and weight, making it easier to integrate the lamp and the circuit.

Various modifications may be made to the connection method for supplying power to the incandescent filament, but it goes without saying that any of these methods fall within the scope of the present invention as long as they are based on the above-mentioned idea.

In this case, the incandescent filament 8 is connected via the capacitor) 9e.
