Next, a resin 16 as a filler is filled from the lower opening 5b of the cylindrical case disposed on the upper side until the entire discharge lamp stabilizer 15 is buried, and a support fitting attached to the optical compensator. The L-shaped tip 21 a of 21 is embedded in the resin 16 and fixed with the resin 16. Since the light compensating device 20 is held in the vertical direction by the support fitting 21, the height of the lighting fixture is increased, and the thickness of the lighting fixture can be prevented.

A power factor improving capacitor 25 is fixed to the back side of the lower lid 12 fitted and attached to the lower opening 5b side of the cylindrical case 5 with screws (not shown). On the front side, a lamp holder 30 to which the HID lamp is detachably attached is fixed with screws (not shown), and the power factor improving condenser 25 and the lamp holder 30 are connected to the discharge lamp stabilizer 15 and the light compensation. The lower lid 12 is fitted to and attached to the lower opening 5b of the cylindrical case, and is mechanically fixed with screws (not shown).

The HID lamp is a general term for a mercury lamp, a high-pressure mercury lamp, a metal halide lamp and the like.

From the incandescent lamp 3
9 are attached.

The light compensator 20 takes about 7 to 10 minutes to stabilize the light flux of the HID lamp at the time of starting and restarting the HID lamp 32. Until is stabilized,
Automatically turns on and off the incandescent lamp 39 placed outside the lighting fixture, and configures a circuit board on which electronic components such as an electrolytic capacitor and a triac are mounted in a case made of, for example, an aluminum material. .

[0011]

As described above, the conventional lighting apparatus provided with an incandescent lamp and an HID lamp has an incandescent lamp until the luminous flux of the HID lamp is stabilized when the HID lamp is started and restarted. The light compensating device for automatically turning on and off the lamp is housed in a cylindrical case, and is disposed between the discharge lamp ballast, which is a heat generating source, and the HID lamp. In addition, the optical compensator uses an electronic capacitor or a triac, which is a temperature-dependent electronic component.

For this reason, there is a problem that an inexpensive lighting fixture cannot be provided because expensive and high-rated electronic components are used.

[0013] The present invention has been made in view of the above points, and it is an object of the present invention to provide a lighting apparatus which can be equipped with an inexpensive light compensator.

[0014]

In order to achieve the above object, a lighting apparatus according to the present invention comprises a cylindrical case having a bottom connected to a lamp holder for detachably mounting an HID lamp, and a cylindrical case. A ballast comprising a laminated core and a coil housed therein and fixed with a filler, a power supply box attached to the upper part of the cylindrical case, and an incandescent lamp arranged outside the cylindrical case, The power box has
When the HID lamp is started or restarted, the incandescent lamp is automatically turned on until the luminous flux of the HID lamp is stabilized,
A light compensator for automatically turning off the light is provided.

In the above configuration, the light compensator mounting the temperature-dependent electronic components is attached to a power supply box disposed above the cylindrical case, and is provided with a discharge lamp ballast as a heat generating source. The HID lamp is housed in the lower part of the cylindrical case opposite to the light compensator,
It is attached to the bottom of the cylindrical case.

For this reason, the light compensating device on which the temperature-dependent electronic components are mounted is arranged at a distance from the discharge lamp ballast, which is a heat generating source, and the HID lamp. The rating of the temperature-dependent electronic component can be reduced.
