Then, a power factor improving capacitor 25 is fixed with a screw (not shown) on the back side of the lower lid 12 which is fitted and attached to the lower opening 5b side of the cylindrical case 5, and on the front side of the lower lid 12. The lamp holder 30 to which the HID lamp is detachably attached is fixed with screws (not shown) . The power factor improving condenser 25 and the lamp holder 30 are connected by the discharge lamp ballast 15 and the optical compensator 20, and the lower lid 12 is fitted and attached to the lower opening 5 b of the cylindrical case 5 , and screws ( It is mechanically fixed with (not shown).
[0008]
The HID lamp is a generic name for a mercury lamp, a high-pressure mercury lamp, a metal halide lamp, and the like.
[0009]
Further, a lead wire 37 connected to the optical compensator 20 and having a socket 38 attached to the tip is led out from the lower lid 12, and an incandescent lamp 39 is attached to the socket 38.
[0010]
The optical compensator 20 takes about 7 minutes to about 10 minutes to stabilize the light flux of the HID lamp when the HID lamp 32 is started and restarted, so that the light flux of the HID lamp is stabilized. Until the incandescent lamp 39 placed outside the lighting fixture is automatically turned on and off, and a circuit board on which electronic components such as an electrolytic capacitor and a triac are mounted is housed in a case made of, for example, aluminum It is composed.
[0011]
[Problems to be solved by the invention]
As described above, the lighting fixture having the conventional incandescent lamp and the HID lamp is a light that automatically turns on and off the incandescent lamp until the light flux of the HID lamp stabilizes at the time of starting and restarting the HID lamp. The compensator is housed in a cylindrical case, and is disposed between a discharge lamp ballast that is a heat generation source and the HID lamp. In addition, an electrolytic capacitor, a triac, or the like, which is an electronic component having temperature dependence, is used in the optical compensation device.
[0012]
For this reason, there is a problem that an inexpensive lighting apparatus cannot be provided because an expensive high-rated electronic component is used.
[0013]
This invention is made | formed in view of said point, and makes it a subject to provide the lighting fixture which can mount an inexpensive optical compensator.
[0014]
[Means for Solving the Problems]
In order to achieve the above object, a lighting fixture according to the present invention has a bottomed cylindrical case having a lamp holder to which a HID lamp is detachably attached at the bottom and having an opening at the top, and the cylindrical case . A ballast composed of a laminated core and a coil housed inside the bottom and fixed with a filler; a power supply box attached to an opening at the top of the cylindrical case and protruding above the cylindrical case; and the cylindrical case An incandescent lamp arranged outside the lamp, and the power box automatically turns on and off the incandescent lamp until the HID lamp light flux stabilizes at the time of starting and restarting the HID lamp. The optical compensator is attached so as to be positioned above the upper opening of the cylindrical case .
[0015]
In the above configuration, the optical compensator on which the temperature-dependent electronic component is mounted is attached to the power supply box disposed on the upper part of the cylindrical case, and the discharge lamp stabilizer and the HID lamp, which are heat generation sources, Is housed in the lower part of the cylindrical case opposite to the optical compensator and is attached to the bottom of the cylindrical case.
[0016]
For this reason, the optical compensator equipped with temperature-dependent electronic components is arranged at a distance from the discharge lamp stabilizer, which is a heat generation source, and the HID lamp, and as a result, is used in the optical compensator. The rating of temperature-dependent electronic components can be lowered.
