Description
The present invention relates to a cartridge replaceable lighting device, and more particularly, a cold cathode fluorescent lamp or an external electrode fluorescent lamp having a long lifetime and low power consumption as a light source for emitting light, and for supplying the light source and power. The present invention relates to a cartridge replaceable lighting device for integrating a power supply device to a cartridge and separating the cartridge from a lighting device by sliding or detaching the cartridge, thereby improving convenience of replacing a light source and reducing replacement cost.
In general, the lighting device is a kind of electrical and electronic products that convert the electrical energy into light energy and use it in real life.
Such a lighting device is provided with a light source that is a representative example of incandescent and fluorescent lamps, and includes a reflector used to reflect the light emitted from the light source or to improve the illuminance.
Therefore, the light source emits light by supplying electricity in a state of accommodating them in a housing, and the reflecting lamp reflects and irradiates light, thereby effectively illuminating a dark place.
On the other hand, the light source installed in such a lighting device that emits light is mainly used incandescent or fluorescent lamps as described above, but the lifespan is usually about 1.500 ~ 5,000 hours, so the unpleasant light source must be replaced. there was.
This inconvenience is not a problem in places where there are not a lot of lighting devices, but in the case of a large number of lighting devices such as large underground parking lots, when the light source that is at the end of its life is replaced by hand, it is necessary to secure enough professional management personnel. In addition, the occurrence of replacement costs is considerable, which is a big problem.
In order to solve this problem, a Cold Cathode Fluorescent Lamp (CCFL) has been proposed, which is disclosed in KR 20-0240207 2001.10.12. [Document 2] KR 20-0379059 2005.03.17.
Furthermore, KR 10-2005-0116573 2005.12.13 discloses a proposal to use an external electrode fluorescent lamp ("EEFL") as a general light source.
That is, the cold cathode fluorescent lamp according to the [Document 1], [Document 2] or the external electrode fluorescent lamp according to [Document 3] is less heat generation than conventional incandescent lamps or fluorescent lamps and can reduce power consumption by 90% to 20%. It has a long service life of 50.000 ~ 60,000 hours.
Therefore, when such a light source is installed and provided in the lighting device, the power consumption can be reduced and the cost can be reduced, the trouble of replacing the light source can be reduced, and the number of professional management personnel can be minimized. .
However, the conventional lighting device is simply a cold cathode fluorescent lamp or an external electrode fluorescent lamp which has a long life and low power consumption as a light source for emitting light, and is very inconvenient to replace an unexpected light source or an end of life lamp. There is a problem.
It is obvious that the cold cathode fluorescent lamp or the external electrode fluorescent lamp may be used for a long time, but may not be permanently used and should be replaced at the end of life.
That is, when looking at this point of view, the light sources according to [Document 1], [Document 2] and [Document 3] mainly use a replacement method of separating only the light source from the lighting device, such as an incandescent lamp or a fluorescent lamp. Is a fatal problem for lighting devices that use cold cathode fluorescent lamps or external electrode fluorescent lamps as light sources.
In the case of the cold cathode fluorescent lamp or the external electrode fluorescent lamp, the replacement is not performed by separating only the light source like the existing incandescent lamp or the fluorescent lamp, but at the same time, the power supply unit (Transfomer or Inverter) that supplies power to the light source is replaced. Because it must be done.
The lifespan of the power supply device is generally manufactured to be proportional to the lifespan of the cold cathode fluorescent lamp and the external electrode fluorescent lamp.
Therefore, as mentioned above, the replacement method that separates only the cold cathode fluorescent lamp or the external electrode fluorescent lamp from the lighting device additionally requires the replacement of the power supply device. This leads to the problem of increasing the number of managers.
An object of the present invention is to integrate a light source for emitting light, a power supply for supplying power to the light source, to a cartridge for reflecting light emitted from the light source, and to separate the cartridge from the lighting device for life The present invention provides a cartridge exchange lighting device that can easily and easily replace these various light sources.
Another object of the present invention is to reduce the time required to replace the light source by separating the cartridge in a slide or detachable manner, a cartridge replacement lighting device that can be replaced quickly with a minimum of professional management personnel To provide.
The present invention for achieving the above object, a light source consisting of a cold cathode fluorescent lamp or an external electrode fluorescent lamp is mounted and integrated on one surface exposed to the outside of the cartridge for reflecting light, the power supply for supplying power to the light source Is integrated on the other side of the cartridge, and the cartridge, in which the power supply and the light source are integrated, is detachably mounted to a housing in which part of the cartridge is open to the outside.
According to the configuration of the present invention as described above, the light source and the power supply device for emitting light to the cartridge is mounted and integrated, the cartridge is easily and simply separated by a slide method or a detachable method from the lighting device, end of life It is a very useful invention such that the time required for replacing the light source can be shortened, the cost can be reduced, and the replacement work can be made quickly with a minimum of professional management personnel.
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

To this end, in the present invention, a cold cathode fluorescent lamp (CCFL) or an external electrode fluorescent lamp (EEFL) is selectively used as the
The cold cathode fluorescent lamp (CCFL) is a fluorescent lamp that is turned on at low temperature without heating the filament and has electrodes at both ends of the glass tube, and contains a certain amount of mixed gas such as mercury, argon and neon, and the inside of the glass tube is coated with a phosphor. have.
The cold cathode fluorescent lamp emits electrons by a high voltage electric field applied to two electrodes, and when electron emission starts, mercury is excited to emit ultraviolet rays, and the ultraviolet rays collide with phosphors on the glass tube wall to emit light.
In contrast, the external electrode fluorescent lamp (EEFL) emits light by inducing a plasma discharge in the glass tube by an electric field applied to the electrode because the electrode is outside the glass tube. Being outside this has the advantage of long life.
