Description

Illumination control device {Apparatus for regulating intensity of illumination}

The present invention relates to an illumination control device, and more particularly, to an illumination control device capable of reducing unnecessary power consumption through phase control without requiring a separate ballast.

In general, fluorescent lamps, especially fluorescent lamps have a negative resistance characteristics and require a high starting voltage. After lighting, a ballast is required to maintain the rated current.

The fluorescent lamp is connected to the ballast to drive a continuous AC voltage from the outside. Therefore, since the fluorescent lamp is driven by a constant high voltage by the ballast, there was a disadvantage in that the illuminance of the fluorescent lamp cannot be adjusted.

Therefore, there is a need for a device capable of adjusting the illuminance of a fluorescent lamp driven by a ballast, and various illuminance control devices have recently been developed. These illumination control devices can be classified into two categories.

That is, an electronic ballast suitable for applying a continuous AC voltage of variable amplitude to a fluorescent lamp and a magnetic ballast for phase controlling the AC voltage used for applying a voltage to a luminaire.

Magnetic ballasts operate in phase control, so they can be used conveniently in fluorescent lamps, but the current trend is changing from magnetic to electronic. The reason is that the electronic ballast has less power consumption than the magnetic ballast, and the electronic ballast has more efficient results than the magnetic ballast in terms of volume and practicality.

The electronic ballast described above can operate the fluorescent lamp for extended periods of time at a low power consumption level without obvious loss in the fluorescent lamp, but has a disadvantage of being expensive. In addition, electronic ballasts can be used for power factor and high power factor.

Korean Patent Application No. 10-1998-0706061 (name: fluorescent dimmer) known before the present application describes a description of a dimmer suitable for applying an AC voltage to a lighting assembly composed of a magnetic ballast.

This description relates to a dimmer comprising a setting means for setting a nominal power for a lighting assembly and control means for phase controlling the applied voltage at each half cycle of the applied voltage. And a processor responsive to setting means for setting a phase angle for the image.

The processor described above sets different phase angles for phase control of the applied voltage and monitors the current at the set phase angle to determine the operating range of the phase angle.

However, according to the technical contents, it is applied to the magnetic ballast to control the operating range by the phase angle control by the processor. Therefore, for the purpose of the phase angle control operation, various additional trigger lines, fluorescent ballasts, wiring work and dimming are performed. It has to be composed of a dedicated ballast and a separate controller, so the configuration is complicated. Therefore, since a separate device is added, there is a problem in that the installation is difficult and the installation cost is expensive.

In another prior art, Korean Patent Application No. 10-1999-012475 (name: fluorescent lighting method and dimming method), which is known before application, preheats the filament of the fluorescent lamp and inputs an external AC power source when the dimming signal of the fluorescent lamp is input. After detecting a zero point of the predetermined time based on the detected zero point according to the amount of light determined from the dimming signal, the switch is turned on to apply power to the fluorescent lamp, so that the brightness of the plurality of fluorescent lamps can be changed from time to time. The technical content is described.

That is, in the fluorescent lamp lighting and dimming method, a zero point is detected from an input power supply voltage, and the detected zero point is phase-controlled by a processor to determine the amount of power applied to the fluorescent lamp and adjust the brightness to a desired brightness.

However, according to the technical contents, not only is the cost high at the time of installation, but even if the illuminance is lowered, there is a problem in that the change in the amount of power is small so that the effect of saving power is not great.

In order to solve the above problems, the present invention does not require a separate dedicated ballast or controller, so that the present invention can be easily applied to a lighting device currently in use, thereby simplifying installation and reducing illumination costs effectively. It is an object to provide an adjusting device.

Furthermore, the present invention, the illumination device can be easily and manually adjust the illuminance, and the object of the present invention is to provide an illuminance control device that can be conveniently used by the user by displaying the illuminance control state to the outside.

Furthermore, the present invention can control the lighting device on / off by reservation at a desired time, and when it is turned on again, it is turned on again with the illumination of the adjusted state at the time of off so that it is consumed by full light when it is turned on again. An object of the present invention is to provide an illuminance control device that can reduce power.
