効果の高いシステムを提供できる。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power saving system for a lighting device for a mercury lamp. 2. Description of the Related Art Conventionally, mercury lamps have been used as lighting means in factories, gas stations and the like. In such sites, relatively high-power mercury lamps are used, and the power difference between them is quite large. Once a mercury lamp is turned off, it takes tens of minutes before it is turned on again. Therefore, the power cannot be frequently turned on and off for the purpose of power saving. As a result, the lighting is left on, and the lighting time of the day is prolonged. In addition, even if there is enough illuminance to work, extra power is consumed because the brightness cannot be varied. Recently, reduction of environmental load has been called for, and power saving is one of the present important issues. Lighting, especially power saving using a mercury lamp as a light source, employs a method of reducing power consumption by lowering the power supply voltage a little below the rated voltage.However, this method reduces power consumption simply by reducing the supply voltage. The illuminance is also reduced by the amount. In this case, a low output is always obtained without being affected by the brightness of the surroundings. Therefore, when the surroundings are dark, sufficient illuminance cannot be obtained. As another power saving method, there is a method of replacing the lighting fixture itself with one having a smaller output than the currently installed one. However, the effect is the same as above, and the existing fixtures are wasted and the environmental load is reduced. Would be contrary to
The present invention is proposed to solve the above problems. [Means for Solving the Problems] No waste is produced,
As a mercury lamp lighting system that obtains illuminance that does not hinder work and enhances the power saving effect, the existing mercury lamp lighting device is used as it is, and its impedance is continuously equivalent between the ballast and the mercury lamp An adjustable adapter was connected, and a controller for providing a signal for changing the impedance of the adapter was adopted. The impedance of the adapter connected between the output side of the existing magnetic circuit type mercury lamp ballast and the mercury lamp changes from 0 to a certain value Z by a pulse signal from the controller. When the impedance is 0, the mercury lamp is lit at the rated output, and the equivalent impedance of the adapter changes by changing the duty of the pulse signal of the controller. As the impedance increases, the output of the mercury lamp decreases. When the equivalent impedance of Z becomes Z, the output of the mercury lamp becomes minimum. In order to manually change the duty of the pulse signal, a volume resistor may be provided in this controller and the value of the volume resistor may be changed. Therefore, the required illuminance can be obtained by setting the value of the volume resistance. Further, in order to automatically change the duty of the pulse signal, an optical sensor may be provided in this controller instead of the volume resistor. If the illuminance of the atmosphere in which the optical sensor operates is set in advance, the duty of the pulse signal automatically changes, and a constant illuminance can always be obtained. FIG. 1 is a block diagram showing an embodiment of a mercury lamp lighting system according to the present invention. An adapter is connected between the output side of the existing magnetic circuit ballast and the mercury lamp, and a control unit of the adapter and a regulator for providing a pulse signal are connected. The power supply of the regulator is connected to the same power supply as the magnetic circuit type ballast, but another power supply does not cause any problem. When power is applied, the signal from the controller is applied to the controller of the adapter, which initially operates to maximize the conduction angle of the triac in the adapter, and the choke in the adapter is completely shorted by the triac As a result, the mercury lamp is turned on by the magnetic ballast (all light state). The control unit is set so that this state lasts for several minutes. When the set time has elapsed, the conduction angle of the triac is controlled by a designated pulse signal according to a command from the controller. A change in the conduction angle of the triac equivalently changes the impedance of the adapter. If the impedance is large, the output of the mercury lamp decreases. If you want to change the brightness of the work surface in a timely manner, attach a volume resistor to the controller and change the value of this volume resistor to change the duty of the pulse signal, and as a result, change the brightness of the mercury lamp. it can. If you want to keep the brightness of the work surface constant, attach an optical sensor to the adjuster.The optical sensor detects the predetermined brightness and automatically changes the pulse signal when the surrounding brightness changes. Change the duty to keep the brightness of the mercury lamp constant. Needless to say, this controller can control a large number of mercury lamp lighting devices by one unit. FIG. 2 is a block diagram showing one embodiment of a number of mercury lamp lighting systems. As described above, according to the present invention, a desired illuminance can be obtained by using an existing mercury lamp lighting device as it is and installing an adapter and a regulator, and a system with high power saving effect can be obtained. Can be provided.
