However, according to the conventional method of supplying electric energy such as lighting, unnecessary waste power is generated in a specific environment that does not require a certain power, and as a result, the life of the lighting is shortened, resulting in huge economic loss at the consumer or national level. There was a problem.

In addition, it is classified as the need to control the fluorescent lamps on the side of the window because it is always on because there is no inconvenience in living because the weather is good on the side of the window in the home, office or factory office.

Therefore, for this purpose, a device for automatically turning off a fluorescent lamp when a certain illuminance or more has been developed, but when a predetermined reference point is crossed, there is a problem in that the lighting is frequently repeated. In other words, it is inconvenient to set the control point separately according to the use environment because it is required to specify the off time point, and if the intensity of illumination is severely changed based on the reference point, the continuous flashing state is made and the user felt very inconvenient.

In addition, the method of measuring the illuminance also includes a lot of error factors for sensing the illuminance, such as the light input from the fluorescent lamp, it appears that there are many problems to be solved until the actual use of the lamp power saving device.

5 is an operation flowchart of the present invention,

When the present invention is roughly described, the power supply unit 10, the light sensing unit 20, the lighting illuminance manual input unit 30, the light sensing time setting unit 40, the average illuminance calculating unit 50 and And a delay illuminance calculator 60, an output range setting unit 70, a microcomputer 80, an output unit 90, a lamp 100, and a fluorescent lamp case 200.

The power supply unit 10 converts and rectifies the applied AC power into DC power, outputs the same, drives the elements constituting various circuits, and outputs the main power to the lamp to light the lamp 100. do.

The light detecting unit 20 is called a CdS sensor whose resistance value is changed according to the brightness of the surroundings, and uses CdS photoconductive cells mainly composed of CdS (cadmium sulfide). The photosensitive unit 10 converts the internal resistance corresponding to the irradiation light energy by the brightness of the ambient light by the characteristics of the CdS photoconductive cell.

That is, the light sensing unit 20 outputs to the microcomputer 80 a proportional light sensing signal of an internal resistance which is converted in correspondence with the sensed ambient light.

At this time, the light detecting unit 20 outputs a low resistance value as the ambient irradiated light (incident light energy) is larger, and outputs a large resistance value as the ambient irradiated light is smaller, so that the photodetector 20 operates almost close to an insulator where there is little light energy. The incident energy of the irradiated light causes current to flow by the internal resistance according to the magnitude.

On the other hand, the light sensing unit 10 of the present invention can not accurately measure the illumination according to the external environment when directly receiving the light from the lamp 100 as the control target cylindrical main support 210 in the lighting case (fluorescent case, 200) Installed in the upper portion of the main support 210, the light-sensitive portion (sensor, 20), and further installed in the case 200, the cylindrical auxiliary support 220 is further installed in the control target lamp 100 directly Minimizing the influence on the sensing unit 20.

In addition, a black anti-reflective layer was further installed on the inner circumference of the cylindrical main support 210 to allow the illuminance of the bottom surface to be input to the light sensing unit 20 as much as possible.

That is, when the main support 210 and the auxiliary support 220 are not used as in the present invention, the light of the control target lamp 100 is input to the sensor, and then the illuminance according to the external environment is not measured, but The illuminance of the control target lamp 100 is measured, making it difficult to specify an accurate ramp-off time, and even there may be no lamp-off time.

Therefore, in the present invention, by additionally installing the main support 210 and the auxiliary support 220 to measure the floor surface of the office or school by preventing the direct light from entering close to the lamp to closely measure the change in the illumination of the external environment I could do it.

The light sensing time setting unit 40 sets the input time of the light input by the light sensing unit 20. In the present invention, the light sensing time is maintained for an average of about 30 minutes, and then the average of the light sensing time is determined. To help.

That is, the conventional power saving lighting device often flickers by designating one illumination time point and turning off the lamp when it is out of this direction, and turning on the lamp when it is not out of it. Since the illumination data is averaged and the lamp off time is specified based on this, the sudden flashing and repetition does not occur.

The average illuminance calculator 50 determines the off time point of the lamp by averaging the illuminance input for the time specified by the light sensing time setting unit 40 so that the microcomputer, which will be described later, can control the lamp off based on this. do.

The delay illuminance calculator 60 is used for averaging the data by continuously delaying the designated time of the light detection time setting unit 40. If the user sets a time of 30 minutes, the delay illuminance calculator 60 discards the initial data. The data input is continuously calculated and averaged to prevent rapid ramp on / off.

In other words, even if the cloud obscurs the sunlight and the intensity of illumination drops sharply, it does not have a big effect if it is averaged over a 30-minute time period.It does not immediately turn on the lamp.On the contrary, even if the intensity rises suddenly due to external influences, it does not immediately affect the average value. Because of this, even if the illumination suddenly rises, the lamp is not turned off if it is within the average value.

This is a sharp difference from the conventional energy-saving lighting lamps, and since the conventional energy-saving lamps cannot be modified after setting a constant illuminance range, when the amount of illuminance changes instantaneously, it is reflected as it is. It may cause a problem in learning or work due to the fast flashing lights such as lighting the lights and turning off the lamps immediately when the clouds are out, but the present invention is designed to turn on or off the lamps based on the averaged data for a user-specified time. Because of this, sudden flashing of the lamp does not occur.

The output range setting unit 70 sets a gap for turning on / off the lamp, and when a reference illuminance value is set, the output range setting unit 70 divides the value into a plus minus as a reference point to set a constant gap.

This is specified in the range of 50 to 100 lux before the product is released, and may be appropriately designated by the manufacturer in addition to this range.

When the output range is set as described above, when the outermost data of the gap is out of the gap, it is determined that the external illuminance has risen more than necessary, and the lamp 100 is turned off and the lowest data of the gap is kept out of the lamp, and then the lowermost level set as the gap is determined. If the data deviates, it is judged that the external illuminance has fallen more than necessary, and the lamp is turned on.

The microcomputer 80 is connected to an optical sensing unit 20, an optical sensing time setting unit 40, an average illuminance calculating unit 50, a delay illuminance calculating unit 60 and an output range setting unit 70, In order to process the data input from the light sensing unit 20, the light sensing time setting unit 40 secures the average data for a specified time, and determines the light-out time, and averaging the data continuously for the specified time. Prevent extinction

As a result, the microcomputer 80 automatically calculates the lamp extinction time reference value based on the light sensing time setting time set by the manufacturer and the specified value of the output range setting unit, and automatically calculates the gap of the operating range. By continuously averaging data over a set time as programmed, it is easy to determine the ramp-off time in any environment.

Meanwhile, in the present invention, the lighting illuminance manual input unit 30 is additionally installed, which means that the producer or the user produces the viscous illuminance at a place where the illuminance reference value is designated by law or a facility that must specify the illuminance value. It is configured to be able to input directly, and preferably set appropriate illuminance reference values for all control devices.

When the light illuminance manual input unit 30 is disposed, the user may control to turn on the lamp 100 unconditionally at a desired point, and thus the microcomputer 80 may control the data value of the light illuminance manual input unit 30 and present. By comparing the light sensing data, if the current light sensing data is lower than the manually inputted data, it ignores other data and controls the lamp to be always on.

Since the lighting illuminance manual input unit 30 specifies a predetermined reference light amount in advance, if the light is turned on to turn on the lighting apparatus in the morning, the lighting apparatus is higher than the light quantity currently measured by the lighting intensity manual input unit. It does not light up.

The output unit 90 is configured to output a control signal of the microcomputer 80 to a lamp, and is usually composed of a transistor or a photo diac, which has a switching function. When the device is switched, the lamp is turned on and the device is not switched. The lamp goes out.

 In addition, the light sensing time setting unit 40, the average illuminance calculating unit 50, the delay illuminance calculating unit 60, and the output range setting unit 70 are all constituent means that can be incorporated in the microcomputer 80, Therefore, all functions are built into the one-chip type microcomputer and the desired operation can be commanded by the program control.

Looking at the operation of the present invention in detail as follows.

First, the manufacturer may designate a predetermined time through the light sensing time setting unit 40 to acquire the average data, and also specify an operation gap through the output range setting unit 70.

In addition, if necessary, the illumination intensity may be input to the illumination intensity manual input unit 20 unconditionally the lamp should be turned on.

Looking at the operation of the present invention in the state that the setting is completed as described above, when the user operates the switch to turn on the lamp 100, the light sensing unit 20 to collect the data for the external light by using this as a point Conduct.

When the data input by the light sensing unit 20 continuously outputs the data to the microcomputer 80, and when the light sensing time setting unit 40 reaches the designated time, the illuminance generated by the operation of the average illuminance calculator 50 Average the values.

Thereafter, the delay illuminance calculator 60 discards the old light sensing data and continuously calculates the new light sensing data to continuously measure the average illuminance data.

Then, the microcomputer 80 compares the illuminance value calculated by the average illuminance calculator 50 with the illuminance value continuously input by the delay illuminance calculator, and always checks whether the micrometer 80 deviates from the gap specified by the output range setting unit 70. do.

If the current average illuminance value is out of the gap specified by the output range setting unit 70, the microcomputer 80 outputs the lamp extinction signal through the output unit 90 to extinguish the lamp 100, and then the average illuminance value. When the output range setting unit 70 falls below the designated gap, the lamp 100 is turned on by outputting a control signal so that the lamp is turned on again.

On the other hand, the microcomputer 80 always compares the illuminance value specified by the illuminance manual input unit 30 with the present illuminance value and turns on unconditionally when the present illuminance value falls below the previously specified illuminance value.

Therefore, when the current illuminance value is higher than the illuminance value specified by the illuminance manual input unit 30 while the lighting device is switched on, the lamp 100 is not turned on, and then the illuminance value is specified by the illuminance manual input unit 30. When it is lower than the illuminance value, the lighting device is turned on, and from that time, the lighting device is counted for a specified time to calculate the illuminance value for lighting off.

That is, when the lighting switch is initially turned on, when the current illuminance value is higher than the value specified by the manual illuminance manual input unit 30, the lamp is immediately turned on to count a time for designating a reference value, and the illumination illuminance is greater than the value specified by the manual input unit 30. If the current illuminance value is low, it will not turn on and if the illuminance falls below the manual input value, the time for specifying the reference value will be counted.

Looking at the control sequence of the present application through the flow chart as follows.

First, a light sensing time and a manual input value are specified in a microcomputer of the system (S10).

After that, when the power switch is turned on to drive the microcomputer (S20).

The microcomputer inputs the current illuminance measurement value from the illuminance sensor and compares the illuminance value manually input (S30).

As a result of the comparison, when the current illuminance value is higher than the manually input illuminance value, the lamp is not turned on because it is relatively bright, and when the current illuminance value is lower than the manually input illuminance value, the lamp is turned on because it is relatively dark (S40).

After the lamp is turned on, the average value of illuminance is calculated for a predetermined time (about 30 minutes) to determine a reference value of the amount of light at the time of lamp off (S50).

Subsequently, the light amount at the time of lamp off is determined by calculating the light amount gap to the reference value of the light quantity, and the initial data is discarded for the specified time and the final data are summed and averaged to determine whether the average value is out of the gap of the light quantity reference value (S60). ).

When the average value of the current light quantity is higher than the light quantity reference value, the lamp is turned off. When the average value of the current light quantity is lower than the light quantity reference value, the lamp is maintained in a state of being turned on (S70).

Finally, when the power switch is turned off by determining the off point of the power switch, the step of turning off the driving of the microcomputer is performed (S80).

Therefore, when the present invention is used, the reference illuminance value is automatically set so that it does not need to set the reference illuminance value separately. When the illuminance value is specified through the manual illuminating unit, the illuminance is lowered below the illuminance value. It provides an advantage that the lighting device can be used more conveniently by turning on the mask.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, various other modifications and variations may be made without departing from the spirit and scope of the present invention. Accordingly, it is intended that the appended claims cover such modifications and variations as fall within the true scope of the present invention.
