Power saving device for discharge lamp {A POWER SAVER FOR DISCHARGE LAMPS}

The present invention relates to a power saving device for a discharge lamp, and more particularly to a power saving device for a discharge lamp that can adjust the intensity of the applied voltage applied to the discharge lamp according to any desired time, thereby obtaining a more effective power saving. .

In general, fluorescent lamps, mercury lamps, sodium lamps, metal lamps, etc. are collectively called discharge lamps because they use light obtained by the discharge after generating a discharge through a gas filled therein. Such discharge lamps generally require a predetermined voltage (eg, 220V or 110V) to initiate discharge.However, to maintain the discharge after the discharge is ignited once the discharge lamp is fired, even if a lower voltage is applied to the discharge lamp without difficulty. It can emit light.

With this in mind, when ignition of a discharge lamp, the discharge is initiated by applying a voltage once, and after the discharge is completed, the lower voltage, that is, the minimum maintenance voltage (where the minimum maintenance voltage is required for a discharge lamp by a human being). Power saving device that exhibits a power saving effect by applying a minimum voltage applied to emit light with illuminance and / or luminance) is already known. Known forms of power saving devices generally include a single winding transformer or a lottery winding transformer.

However, we often need a discharge lamp that emits light with higher illumination and / or brightness than the illumination and / or brightness of a power saving type discharge lamp that frequently emits light at such a minimum holding voltage. In other words, since the illuminance and / or the luminance of the discharge lamp which emits light at the initial applied voltage or the voltage higher than the minimum maintenance voltage for starting the discharge of the discharge lamp is higher than the discharge lamp that emits the light at the minimum maintenance voltage, the minimum maintenance voltage may be In other words, there is a need for a discharge lamp that emits light at a voltage higher than the initial applied voltage or the minimum holding voltage.

As an example, when the street lamps which have been turned off during the day are discharged to the first applied voltage in the early evening and continue to be discharged at the voltage switched to the minimum maintenance voltage for the purpose of power saving, the discharge lamp in this case is relatively If the ambient light is bright and the distance from the street light is small, the minimum maintenance voltage can fully exert its original effect. The back may not fully exhibit its original effects. In addition, these areas are characterized by the fact that there are only a lot of people coming and going in the immediate evening, including early evening.

Therefore, as a solution to the problem of the street lamps installed in these areas, there is a method to apply a voltage higher than the minimum maintenance voltage or the same voltage as the initial applied voltage, or to make the installation distance of the street lamps more compact, which will be described later. In case of economics, the effectiveness is somewhat insufficient. Therefore, in consideration of only the above-described case, when a voltage higher than the minimum holding voltage or a voltage equal to the initial applied voltage is applied to the street lamp, there is a problem that the purpose of power saving is faded.

In other words, since no discharge lamp has yet been provided for controlling the intensity of the applied voltage according to an arbitrary time, streetlights applied at a voltage higher than the minimum holding voltage or at the same voltage as the initial applied voltage as described above are artificially adjusted. If it is not, the original purpose of the energy-saving discharge lamp is faded because the light is continuously emitted at the voltage.

Therefore, the present invention was devised to solve such a problem, and the object of the present invention is to adjust the intensity of the applied voltage applied to the discharge lamp according to any desired time, thereby discharging the power can be saved more effectively It is to provide a sleep saving device.

The energy saving device for a discharge lamp of the present invention for achieving the above object has a first coil, a second coil positioned opposite to the first coil while having a winding direction different from the first coil, and a longitudinal direction of the second coil. One or more taps arranged along the grid, one or more switches that can be selectively connected to any one of the tabs, a timer connected to each switch, a relay corresponding to the one or more switches, It is characterized by consisting of a timer connected to the relay.

In this configuration, only one switch is simultaneously connected to one tap, the tap and the switch simultaneously ignite a discharge lamp with the switch and the relay open when the power is first applied, and after the ignition of the discharge lamp is completed, At the time of, the switch connected to any one of the one or more taps and the relay connected to the switch are short-circuited, and when a predetermined time elapses, the switch connected to any one of the one or more taps and the relay connected to the switch are again Simultaneously with the opening, the switch connected to one of the one or more taps and the relay connected to the switch are shorted at the same time.

Preferably, the voltage applied to the discharge lamp while the switch connected to any one of the one or more tabs and the relay connected to the switch is short-circuited is equal to the voltage applied to the discharge lamp through the first coil in a state in which the second coil is opened. On the other hand, when the switch connected to any one of the one or more taps and the relay connected to the switch is shorted, the voltage applied to the discharge lamp is such that the switch connected to any one of the one or more taps and the relay connected to the switch are shorted. The short circuit may be applied to the discharge lamp with a voltage lower than the voltage applied to the discharge lamp.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention in detail as follows.

1 is a circuit diagram showing a preferred embodiment of the present invention.

As shown, in one embodiment of the power saving device for a discharge lamp, there is a pair of coils C1 and C2 having different winding directions, and an insulator INS is located in the middle thereof. Therefore, when an external voltage is applied, the pair of coils C1 and C2 act as lottery-type transformers with polarity.

Four tabs T1 to T4 are provided in the longitudinal direction of the second coil C2, and two tabs (that is, tabs T1 (T2) or tabs T3 and T4) are paired. And correspond to switches S1 and S2, respectively. In other words, the switch S1 corresponds to the taps T1 and T2 and the switch S2 corresponds to the taps T3 and T4. Here, each switch is selectively connected to any one of the pair of taps corresponding thereto, and the operation of such a switch can be made manually or automatically, which is known in the art.

Thus, the moving limit range of the switches S1 and S2 is between a pair of taps (that is, taps T1, T2, or T3, T4). In addition, among the pair of coils C1 and C2 serving as the lottery transformers, the intensity of the voltage reduced in accordance with the positions of the taps T1 to T4 provided in the second coil C2 is T1> T2> T3. > T4 order.

When the switches S1 and S2 and the tabs T1 to T4 are installed as described above, the relays R1 and R2 are connected to the respective switches S1 and S2. In particular, these switches S1 and S2 and relays R1 and R2 are connected with a timer (not shown) which can set the time so that the operation time thereof can be controlled. In an embodiment of the present invention, a time is set in the timer so that the switch S1 and the relay R1 operate in preference to the switch S2 and the relay R2.

A pair of terminals P1 and P2 are connected to an external power supply E, another pair of terminals P3 and P4 are connected to a discharge lamp L, and ST is a ballast. .

In one embodiment having such a configuration, the switches S1, S2 and relays R1, R2 are opened in the first stage of attempting to ignite the discharge lamp L. FIG. Therefore, the voltage applied from the external power source E starts to discharge to the discharge lamp L through a closed circuit including the first coil C1. At this time, no electricity flows through the second coil C2. As such, when the discharge lamp L is ignited, the first relay R1 is shorted by the operation of the timer and at the same time, the first switch S1 taps any one of the pair of taps T1 and T2. It is connected to T1 (at this time, the switch S2 and the relay R2 are open).

Accordingly, a voltage reduced in pressure than the voltage flowing through the first coil C1 is applied to the discharge lamp L. In this case, the discharge lamp L is not turned off due to the characteristics of the lottery transformer, and is reduced in the taps T1 and T2. The intensity of the applied voltage may be equal to or lower than the voltage passing through the first coil C1 described above, which is possible according to a change in the position of the taps T1 and T2 installed in the second coil C2.

After a predetermined time, that is, a set time of the timer connected to the switch S1 and the relay R1 has elapsed, the first relay R1 and the first switch S1 are opened, and then the second relay R2 is opened by the timer. ) Is short-circuited and the second switch S2 is connected to any one tab T3 of the pair of taps T3 and T4. Then, the voltage reduced more than the voltage reduced in the above-described tap (T1) (T2) is applied to the discharge lamp (L), which voltage and the minimum holding voltage for maintaining the discharge of the discharge lamp (L) as described above It may be the same or more or less, which is possible according to the change of the position of the tabs T3 and T4 provided in the second coil C2.

On the other hand, in this configuration, the position of the tab provided in the second coil as described above is not limited as shown in FIG. This is because, in the single winding transformer or the lottery transformer, the strength of the depressurized voltage differs depending on the position of the tap provided in the coil. And the number of tabs can also be arbitrarily increased or decreased, which only results in device design problems. It is also to be understood that the position and number of switches and relays may also change as the position and number of taps change.

Thus, in the present invention, since the switch connected to each tap and the relay connected to the switch can be controlled by a timer, a discharge lamp that emits light with relatively high illuminance and / or brightness can be selectively used as necessary.

As described in detail with a conventional example, that is, a street lamp, as described above, when the discharge of the street lamp is started, it is a time when a lot of people come and go, so that each of a plurality of timers (for example, the switch S1 and the relay R1) It is a connected timer, and hereinafter referred to as a "primary timer" is set within a time range in which a lot of people come and go.

Then, as described above, the street lamp after the discharge is started is discharged because the switch connected thereto and the relay connected to the switch (that is, the switch S1 and the relay R1) are short-circuited for a range of time set in the primary timer. The reduced voltage may be applied at the same or relatively lower voltage than the applied voltage to start the operation. Thus, a discharge lamp that emits light with high illuminance and / or brightness is provided.

On the other hand, among the plurality of timers except the first timer (for example, a timer connected to the switch S2 and the relay R2, respectively, hereinafter referred to as a 'secondary timer'), the traffic of a person is within a limited time range. Set it.

The switch connected to it by the primary timer that has exceeded the set time range and the relay connected to the switch (ie, switch S1 and relay R1) are opened and at the same time the switch connected to it by the operation of the secondary timer. And the relay connected to the switch are short-circuited.

Therefore, the discharge lamp may be applied at a voltage reduced more than the voltage applied by the above-described primary timer. The voltage applied by the secondary timer may be the same as the minimum holding voltage for holding the discharge lamp as described above. It may be more or less. As a result, it is possible to provide a discharge lamp that emits light with low illuminance and / or brightness, and, if necessary, a voltage switched more than the minimum holding voltage can be applied, thereby saving more power than a conventional power saving device for a discharge lamp.

As described above, according to the present invention, the strength of the voltage applied to the discharge lamp by switching the pressure from the tap installed in the coil serving as the lottery transformer is applied to the timer connected to the switch connected to the tap and the relay connected to the switch. Since control can be made by setting a desired time, the degree of light emission of the discharge lamp, that is, illuminance and / or luminance, can be adjusted according to an arbitrary time and place.

In addition, when a discharge lamp having a lower degree of light emission is required, it is possible to save more power because the discharge of the discharge lamp can be maintained by being relatively lower than the minimum holding voltage capable of maintaining the discharge of the discharge lamp.
