Description

[0001] The present invention relates to a high-pressure discharge lamp,

The present invention relates to a high-pressure discharge lamp lighting apparatus, and more particularly, to a high-pressure discharge lamp lighting apparatus excellent in color rendering, excellent in efficiency, and easy to control a light distribution characteristic.

2. Description of the Related Art [0002] In general, a lighting apparatus is a device for illuminating a surrounding area by emitting light at night or in a dark place. Recently, various studies have been conducted for energy saving and efficient light control.

Conventional lighting apparatuses are generally in the form of halogen lamps, fluorescent lamps, mercury lamps, or high-pressure sodium lamps, but their preferences are rapidly deteriorating due to high energy consumption due to high power consumption.

In particular, when a halogen lamp, a fluorescent lamp, or a mercury lamp is used as a lighting device, the life span is short and maintenance costs are high and environmental pollutants are generated in a large amount during disposal.

For this reason, an illumination device using a light emitting diode (LED) as a light source has been actively studied instead of the above illumination device.

A lighting apparatus using such a light emitting diode as a light source is disclosed in various prior art documents including domestic patent publication No. 2012-0049576.

However, when a light emitting diode is used as a light source, when only one light emitting diode is used, since monochromatic light is emitted, it is difficult to realize a natural color, resulting in a problem of poor color rendering.

Therefore, it is necessary to improve the color rendering property with one light source and at the same time to have an efficient lighting device.

In addition, it is necessary to provide a lighting device capable of controlling light distribution characteristics in various ways according to the use or the surrounding environment.

These advantages are mainly used in street lamps and outdoor lighting. In recent years, the range of use for the exhibition lighting for golf courses, department stores, and large shops has been expanded.

 In particular, ceramic metal halide lamps made of ceramic arc tube are superior to conventional metal halide lamps in light efficiency, color rendering, and life span.

However, ceramic metal halide lamps require higher ignition voltages (about 3 kV to 5 kV) than conventional metal halide lamps. Therefore, in order to light the ceramic metal halide lamp, a ballast 30 that generates a higher ignition voltage than the conventional one must be provided. In addition, since the ceramic metal halide lamp is very sensitive to acoustic resonance phenomenon as compared with other metal halide lamps, the stabilizer 30 should be designed so as to prevent acoustic resonance.

The inner lamp (10) is provided to be respectively installed in a plurality of high pressure discharge lamps (L). In the present embodiment, it is preferable that the inner sheath 10 is formed as a facet as shown in FIG.
