本発明はバイメタルスイッチを有する放電灯の点灯装置
に関するもので、バイメタルスイッチの動作を制御する
フィラメントを利用して、簡単な榊成で主照明及び補助
照明の両方を１つの放電灯で実現したものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lighting device for a discharge lamp having a bimetal switch, and uses a filament that controls the operation of the bimetal switch to control both the main lighting and the auxiliary lighting in one with a simple construction. This was achieved using one discharge lamp.

ｓ４内に収容されている。The figure shows an embodiment of the present invention, in which a high-pressure discharge lamp 3 is connected to both ends of an AC power supply 1 having a power supply voltage changeover switch S via a check coil 2, which is a ballast containing an inductive impedance. It is becoming. The high-pressure discharge lamp 5 is formed of a parallel circuit of an arc tube s1, a normally closed bimetal switch 32, and a series circuit of a filament 33 for controlling the bimetal switch, and the parallel circuit is housed together in an outer bulb s4. ing.
切付スイッチＳが高電圧側傍点Ａに投入されている時に
は、かかる放電灯点灯装置は通常の動作をし、高圧放電
ランプ３は定格点灯を行なう。When the cut-off switch S is turned on at the high-voltage side point A, the discharge lamp lighting device operates normally, and the high-pressure discharge lamp 3 performs rated lighting.

ルスイッチ８２が開く。この時チ■−クコイル２にいわ
ゆるキック電圧が発生し、この電圧で発光管３１が放電
を開始し、定格点灯に至るものである。That is, first, a current flows through the filament 33 through the normally closed bimetal switch 32, which is heated and the bimetal switch 82 opens. At this time, a so-called kick voltage is generated in the check coil 2, and this voltage causes the arc tube 31 to start discharging, resulting in rated lighting.
次に、切蕾スイッチＳを低電圧側接点Ｂに切り換えると

る。Next, when the cut-off switch S is switched to the low voltage side contact B, the filament 3s is similarly heated and glows red, but the bimetal switch s2 does not operate because the amount of heat is small. Therefore, the arc tube 85 does not reach discharge, and the filament 3
A state is obtained in which only the light source 3 is heated red-hot and emits light, and this light can be used for auxiliary illumination as a night light, for example.

ている状態をも実現でき、簡単な枯成で、土、補助両方
の照明を得ることができた。Moreover, the filament 33 becomes red hot immediately after the power is turned on, so even if you are not using it as a night light, if you want to switch to auxiliary lighting immediately without waiting until the arc tube 31 is completely lit, you can switch because the filament 33 is already heated. As soon as the switch S is switched to the contact A side, the arc tube 31 will be discharged, and the main illumination state can be obtained more quickly. By changing the voltage applied to the lamp, it was possible to achieve a state in which only the filament emitted light, and with simple drying, it was possible to obtain both soil and auxiliary illumination.
