DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a thermally responsive switch type discharge lamp lighting device using bimetal.

[Background technology]

FIG. 1 shows one of the conventional examples. In Figure 1 (a), F is a discharge lamp, which is connected to an AC source E via a ballast. It's still fil +21r metal and 5. As shown in Fig. 1 Φ)
It is heated by 2. bimetal(
1) (2) is a metal plate (la) with a low coefficient of thermal expansion (2a
) and a metal plate (lb) (2b) with a high coefficient of thermal expansion are bonded together, and when the two plates (H1, Hz) are heated, they curve in the directions shown by arrows P and Q, respectively. It is something.

However, in the conventional example, usually bimetal + I) (24

At 1φ, it takes a long time for the first point to close, and when the voltage is high, if the opening interval of the contacts is set to an appropriate size, conversely, when the voltage is low, the contact There is a drawback that it is not possible to maintain Ql in an open circuit state.

■If you try to turn on the light source immediately after turning off the light source, pressure will be applied to both ends 11 of the starting device and the source υ.

By keeping the contact force constant in order to keep the contact distance constant, it is possible to completely prevent the contact spacing caused by fluctuations in lamp voltage, etc., and always maintain an appropriate contact spacing. This is a device whose purpose is to provide a light lighting device.

2. Figures α0 to 5 are circuit diagrams for explaining the operations at the time of starting, lighting, and restarting, respectively, in the actual power supply y1. First, when the power is turned on at the time of starting, as shown in FIG. 5, the preheating current flows through the iodine D and the bimetal l1. In addition, the l temple with the opposite phase has a bimetal (2

is opened, and due to the heavy pressure generated by the ballast, a sound is emitted and light F lights up. Next, when the light is on, as shown in Figure 4, a constant voltage diode ZD is connected in parallel to diode D1 and 111 connected in series, and the voltage regulator diode ZD is connected in parallel to the diode D1, which is connected to the diode D1 and 111 connected in series.

As shown in Figure 5, the lighting discrimination circuit (3) turns on because the IJi pressure on both sides of I'j is lightning, and the current I4 flows.
It, theta H7 generates heat, heats the bimetal (2), and forcibly closes the contact S. At this time, a constant voltage of H1 was maintained overnight.

In this case, a 11-voltage diode Z1)1 is used. Wood carving H @ BljVc When the discharge lamp F lights up and the Ichikawa at both ends of the discharge lamp F decreases, the constant 'quasi-pressure tight Z1) turns off by 1, and the current lI, becomes υ

In Figure 1, the base voltage of the transistor R1 is controlled by a series circuit of a constant ffi, an IE tie A-D, and a resistor R. When the light is not lit, the value is 1, and when the register Tr1 is turned off, the value is set to v1. Furthermore, in the 81st embodiment, the current flowing through theta 1 is increased by turning on and off the l-transistor 1lr2 connected in parallel to -911°. When the discharge lamp F is not lit, the constant voltage diode ZD is turned on and the transistor rr1 is turned on, so the transistor 'I:'I'
is turned off, and the controller H2 is charged with a 6-year-old bff. At this time, the upper limit of the voltage υ11 applied to the shunter H2 or the constant voltage diode ZD2 increases ft1l.
``Limited'', it has become. Also, when the discharge lamp F is lit, the constant voltage regulator ZD is turned off, the transistor 1 [r1 is turned off, and the transistor Tr2i-J;! The signal σ1t flowing to the filter H2 is turned off.

[Efficacy of Seimei J The present invention is made up of 4 pts as above, and -
A discharge lamp having a phantom filament y1, a ballast of 1, ri and n installed in series between the end of the filament of the discharge lamp on the m source side and an AC power supply, and a bimetal of π1. and a second bimetal, and a discharge lamp main body.
One end is connected to the 19th connection point between the diode and the connection point, and one end is connected to the 19th connection point between the diode and the connection point, and the first bimetal is heated when the current is applied. a first resistor 9 that connects the first resistor 9 to open the contact; a resistor that connects the first resistor 9 across the contact; and a resistor connected across the series circuit of the diode and the first resistor 9. , a constant voltage diode that makes the voltage applied to the first switcher constant through the diode, a lighting discrimination circuit that determines whether or not the discharge lamp is lit, and a lighting control circuit that determines whether or not the discharge lamp is lit. At the same time, the output lIr of the lighting discrimination circuit is energized, and when energized, the second bimetal is heated and the contact is closed. Fluctuations in the lamp voltage due to changes in the
The hit applied to Noshi-9 is always stubbornly suppressed by the LE rt1 constant voltage diode, thereby making the light and heat 11 of the first Shi-9 constant. Therefore, it is advantageous to be able to always maintain the boiling point at H for an appropriate period of time6 Still, in the present invention, it is possible to turn off the power once from the lighting state and then immediately turn it back on. When trying to light the lamp, even if the voltage across the discharge lamp becomes as high as the power supply voltage, the voltage applied to the first switch 9 is kept constant by the fixed voltage diode. Therefore, what if the time required to restart the emitting lamp is 100%? The advantage is that the source heat h1 of Af, 2-9 can be reduced, and the time it takes to start the 1t + 9 of the discharge lamp can be shortened by using the same M wind. be.
