Description

Apparatus for a dimming and selective swtching of fluorescent lamps

The present invention relates to a dimming (dimming) of a fluorescent lamp and a selective lighting control device, and more particularly to a lighting device having a plurality of fluorescent lamps can be selectively turned on or off by selecting a plurality of fluorescent lamps, The present invention relates to the provision of a configuration further provided with a dimming function for adjusting illuminance.

In general, fluorescent lamps have high energy consumption efficiency and high brightness compared to incandescent lamps, and thus are widely used in homes or industries.

Such fluorescent lamps have a number of problems described below despite the advantages of high efficiency and high brightness.

(1) Since most fluorescent lamps have only a function of turning on or off, the user cannot adjust the light source to the degree of illuminance desired by the user.

This is the degree to which the illuminance is difficult to control when it is desired to be used as an auxiliary lighting device during the day or at night in the home or industry, which is due to the property of lighting by the discharge of the fluorescent lamp itself.

Therefore, an apparatus capable of selectively setting illuminance of fluorescent lamps has been desired.

(2) Most households and industrial companies use a plurality of fluorescent lighting devices formed by linking two or more fluorescent lamps due to insufficient illumination by a single fluorescent lamp. By turning on or turning off all of them, there is a problem of wasting electric energy by having a problem of turning on or turning off a plurality of fluorescent lamps even where a relatively low illuminance is sufficient.

(3) Most of the switches for fluorescent lamp lighting are switches attached to the wall, and by turning on and off, there is an inconvenience of having to operate the wall switch even when going to bed.

In view of these problems, there has been a light switch that can be operated as a remote control in the past, but since it has only a single purpose of remote operation, it is very complicated to attach and use separately at expense, and electrical work such as changing the internal wiring is required. It is extremely limited.

A remote controller (R) having (S) and operated by the signal receiving unit (S) and an infrared light method can be individually selected to turn on or off all or any one of the individual fluorescent lamps (L1, L2). Dimming of any one or all of the) is characterized in that to change the illuminance.

The circuit diagram for lighting a fluorescent lamp from the prior art is shown in FIG.

The switch SW for dot and extinguishing preheats the first filament F of the fluorescent lamp while the power is turned on to the primary T1 side of the ballast coil, and at the same time, a high voltage is momentarily applied at the coil output terminal of the secondary side T2 coil of the ballast coil. This high voltage is triggered through the condenser (C1), resistor (R1), triac (SSS), diode (D1), and the high voltage discharges the second filament (F2) by preheating and applying a high voltage. F) Since the phosphor in the room is turned on to perform lighting as a trigger of a high voltage, a dimming operation for illuminance control is fundamentally impossible.

3 to 4 illustrate circuit configurations devised to achieve the purpose of the dimming and selective lighting control apparatus of the fluorescent lamp of the present invention.

The dimming and selective lighting control apparatus of the fluorescent lamp of the present invention is constituted as a CPU incorporating an operation program to perform dimming control and selective lighting, and an additional element cooperative with the CPU.

As shown more clearly in FIG. 3,

The voltage drawn from the AC power source AC is applied in parallel to the plurality of input terminals 1-2 and 3-4 of the transformer T. The input terminal 1-2 is connected to the first filament f1 of the fluorescent lamps L1 and L2 as a load for lighting the fluorescent lamp, respectively.

The input terminal 3-4 is for use as a main driving power source of the dimming and selective lighting control device of the fluorescent lamp of the present invention, and the CPU 20 is connected to the output terminal 7-8.

The output terminal of the input terminal 1-2 has one side of the second filament f2 of the fluorescent lamps L1 and L2 via the stabilizing capacitors C2 and C3 in order to supply power to the plurality of fluorescent lamps L1 and L2. Each connected to a line.

The other line of the second filament f2 of the fluorescent lamps L1 and L2 is configured such that power is applied via the ballast coils T1 and T2 under the control described below.

The AC power supply 100 is applied and the power is applied as driving the switch 200 for the user's point-off operation, and the transformers T1 and T2 for driving power supply and preheating are supplied via the surge protection circuit 300. The power source detecting unit 500 is also applied to the operation CPU 20 as the power source from the transformer T2 for the circuit driving power source, via the diesel power source 400.

In addition to such a configuration, the CPU 20 performs preheating operation according to the signal of the signal receiver 600 and the signal receiver 600 for detecting a transmission signal of the remote controller R of various methods such as an infrared drive. It has a preheating driving unit 700, a lighting driving unit 800 to perform the lighting and the illumination control unit 900.

The output from the CPU 20 by such a signal is the first drive driver D1 and the second drive driver (D1) for applying a voltage to the magnetic ballast coils CL1 and CL2 for driving the fluorescent lamps L1 and L2, respectively. Each fluorescent lamp L1, L2 is turned on via D2).

The selective driving of the remote controller R and the signal receiver 500 corresponding thereto may be as follows.

When both the fluorescent lamps L1 and L2 are turned on, and when one of the fluorescent lamps L1 and L2 is turned on, the fluorescent lamps L1 and L2 are configured as an illuminance control switch section for adjusting the illuminance of any of the lit fluorescent lamps L1 and L2.

Therefore, the remote controller R of the preferred configuration of the dimming and selective lighting control device of the fluorescent lamp of the present invention is selected with the ON / OFF key 50, the first drive key 51, and the second drive key 52, respectively. It is preferable to have five operation keys of the dimming high key 53 and the dimming low key 54 for the fluorescent lamps L1 and L2.
