The present invention relates to an intelligent luminaire that is employed in a fluorescent lamp stand, and more particularly, to an intelligent luminaire that is adapted to the ambient light, so that the lamp lighting / off request and the corresponding operation can be automatically performed.

In general, a fluorescent lamp stand as an example of a luminaire, which is proposed as a kind of electronic product to adjust illuminance of a specific area, as shown in FIG. 1, allows a plurality of functions to be selected for the luminaire. On the key input unit 10 having the selection buttons 10a to 10d, for example, when the user touches the selection button 10a, a lamp 11 such as a fluorescent lamp is turned on and then touches the selection button 10b. When the illuminance of the lamp 11 is adjusted to, for example, one-stage brightness, and if the selection button 10c is touched, the illuminance of the lamp 11 is adjusted to, for example, two-stage brightness, and the selection button 10d is touched. The illuminance of the lamp 11 is adjusted to, for example, three levels of brightness.

As such, lighting devices such as a fluorescent lamp stand which is controlled to blink and output are usually installed on a desk or a workbench. When reading a book on a desk or performing a work on the workbench, for example, sufficient illuminance even when the lighting device is not turned on. (E.g., illuminance from a light source installed in the ceiling), even if the state is secured and unnecessarily to turn on the luminaire unintentionally, there are many cases, and reading or working despite the state in which the luminaire needs to be turned on In many cases, the person who is immersed in and continues to read or work without turning on a lighting fixture unknowingly lowers his vision.

Accordingly, the present invention has been made in view of the above circumstances, and an object thereof is to provide convenience for use and unnecessaryness by automatically performing a lamp lighting request or a lamp lighting request and an operation according to an luminaire such as a fluorescent lamp stand adapted to ambient light. It is to provide an intelligent luminaire to reduce power loss.

According to a preferred embodiment of the present invention to achieve the above object, the illumination request signal from the illumination input unit and the key input unit, the illumination detection unit for detecting the ambient illuminance, a plurality of thresholds for determining the detected current illuminance are stored in advance Microcomputer that performs warning signal generation control operation for notifying lamp ON / OFF by determining lamp ON / OFF based on the current illuminance according to the presence or absence of lamp ON / OFF, and lamp ON / OFF control operation accordingly, and warning under the control of the micom There is provided an intelligent luminaire comprising a warning means for performing the operation.

Preferably, the microcomputer controls so that a warning operation for the lamp lighting request is performed if the current illuminance is not more than a threshold that is impossible to read the text at all and is less than a threshold that is dark enough to cause eye fatigue. If the illuminance does not change abruptly, it is controlled to release the warning. If the illuminance changes rapidly, the lamp is turned on when the light request signal is input.

In addition, the microcomputer is configured to turn on the lamp when the current illuminance is less than a threshold that does not require the assistance of the lamp when there is a lighting request signal, while the current illuminance does not require the assistance of the lamp. When the threshold value is more than the threshold value, the lamp warning request operation is controlled to be performed, and the lamp is turned on only when there is a light request signal again for a predetermined time.

On the other hand, the warning means comprises a warning light driver operating under the control of the microcomputer, a warning light flashing by the warning light driver, a buzzer driving under the control of the microcomputer, and a buzzer for generating a buzzer sound by the buzzer driving unit. .

In addition, only the warning lamp flashes during the warning operation for the lamp lighting request.

In addition, the warning light and the buzzer are operated together during the warning operation for the lamp off request.

According to the embodiment of the present invention configured as described above, when the user does not request the lighting, if the current illuminance detected by the illuminance sensor is dark enough to give fatigue to the eyes, a warning operation for lamp lighting request (warning light flashing operation) If the current illuminance does not suddenly flash afterwards, the warning is canceled.If the current illuminance changes rapidly, the lamp is turned on when the lighting request signal is input. When the illuminance is below a threshold that does not require the help of the lamp, the lamp is turned on. On the other hand, when the current illuminance is above a threshold that does not require the help of the lamp, a warning operation for lamp extinction is required. Operation and alarm operation), and the lamp is turned on only when the signal for turning on It is or the like.

Hereinafter, an intelligent lighting device according to an embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

2 is a block diagram of an intelligent lighting device according to a preferred embodiment of the present invention, the embodiment of the present invention is the key input unit 10, the illumination intensity detection unit 20, the memory unit 25, the microcomputer 30, The lamp driver 35, the lamp 11, the warning light driver 40, the warning light 45, the buzzer driver 50, and the buzzer 55 are included.

Here, the illuminance detecting unit 20 detects the current ambient illuminance according to whether the lamp 11 is turned on or off, and the illuminance detecting unit 20 is disposed between the power supply terminal Vcc and the ground of the well. CdS cell and knife, which is a resistor (R) and a photoelectric conversion element, are constructed by connecting an illumination sensor (see FIG. 3: 20a) in series to each other, and a microcomputer that describes the current illuminance detected by such a circuit configuration. It is applied to (30).

The memory unit 25 stores in advance a plurality of thresholds for determining the level of the detected current illuminance. The plurality of threshold values assumed in the present invention are such that the letters and the like cannot be read at all, such as at night time. Threshold (a) for illuminance, the threshold (b) for illuminance enough to read the text, but dark enough to give eyes fatigue, and to the extent that you do not need the help of the lamp 11 for reading or working The threshold c means the illuminance of.

The microcomputer 30 controls the general operation (eg, power on / off operation, brightness adjustment operation) of the corresponding luminaire according to the signal from the key input unit (see FIG. 1: 10), and the key input unit 10. In accordance with the presence or absence of the light request signal is applied in the) based on the current illuminance from the illuminance sensor 20 determines whether it is time to turn on or off the lamp to generate a warning signal to inform the lamp on / off The control operation and the lamp lighting / lighting control operation accordingly are performed.

For example, when the microcomputer 30 has a light request signal, if the current illuminance is less than or equal to a dark threshold (that is, between a threshold value (a) and a threshold value (b)) to cause eye fatigue, the lamp needs to be turned on. The warning operation is controlled to be cooled and controlled to release the warning when the current illuminance does not change drastically, while the lamp is turned on when the light request signal is input when the current illuminance changes abruptly. Here, the sudden change to the current illuminance is, for example, 20 (AV / DELTA T), where DELTA T: sampling period and AV: voltage flowing through the illuminance sensor 20a during the sampling period. It is judged that there is a sudden change in the value obtained over several times when the value before and after the difference greatly differs from each other (for example, when moving to near a luminaire to which the present invention is employed to view a book or work). Done.

In addition, when the lighting request signal is present, the microcomputer 30 turns on the lamp 11 that is normally performed when the current illuminance is less than or equal to the threshold value c that does not require the help of the lamp 11. On the other hand, when the current illuminance is greater than the threshold (c), the lamp is turned off so that a warning operation for requesting lamp off, which means that the lamp 11 does not need to be turned on, is performed, and the lamp is turned on only when there is a turn-on request signal again for a predetermined time. (11) is controlled to turn on.

The lamp driving unit 35 turns on / off the power of the lighting fixture or controls the brightness of the lamp 11 under the control of the microcomputer 30.

Warning light driving unit 40 is to operate the warning light 45 under the control of the microcomputer 30, the warning light 45 is made of a red LED, for example, as shown in FIG. It is provided in the lower part of the assumed luminaire (that is, the part in which the key input part 10 is installed).

The buzzer driver 50 operates the buzzer 55 under the control of the microcomputer 30, and the buzzer 55 is the lower portion of the lighting device assumed in the present invention as shown in FIG. The key input unit 10 is installed).

Here, in the embodiment of the present invention, only the warning light 45 is flashed during the operation of the warning lamp request for lamp lighting request performed under the control of the microcomputer 30, while the control of the microcomputer 30 is performed. The warning lamp 45 and the buzzer 55 operate together in the warning operation for the lamp off request.

Next, the operation of the intelligent lighting device according to the embodiment of the present invention configured as described above will be described based on the flowchart of FIG. 4.

First, the microcomputer 3 determines whether a light request signal (that is, a signal input when the user touches the selection button 10a) is input from the key input unit 10. If it is input (YES in step 400), it is determined whether the current ambient illuminance provided by the illuminance detecting unit 20 is sufficient illuminance (that is, more than the threshold c) to avoid turning on the lamp 11. As a result of the determination, when the threshold value c or less previously stored in the memory unit 25 (NO in step 410) is controlled, the lamp driving unit 35 is controlled to turn on the lamp 11 (step 420). If the ambient illuminance is above the threshold c (YES in step 410), the warning light driver 40 and the buzzer driver 50 are operated together to indicate that it is not necessary to turn on the lamp 11. At the same time, the buzzer 55 sounds (step 430).

Subsequently, the microcomputer 30 determines whether the lighting request signal is input again by the user from the key input unit 10, and when the lighting request signal is input again within a predetermined time (for example, about 5 seconds) ( In step 440, the lamp 11 is turned on by performing the control operation in step 420, but when the predetermined time has elapsed while the lighting request signal is not input again (YES in step 450). (11) is kept on without turning on (step 460).

At this time, the warning light 45 is turned off and at the same time the buzzer 55 also stops the operation.

However, when the lighting request signal is not input by the user in step 400, the process proceeds to step 470, and the microcomputer 30 determines whether the current illuminance is less than or equal to the threshold (a) and is less than or equal to the threshold (a). YES in step 470, the control returns to step 400, while the current illuminance is compared with another threshold (i.e., b) if it is above the threshold a (NO in step 470). As a result, if the current illuminance is above the threshold b (YES in step 480), the process returns to step 400, while if the current illuminance is below the threshold b (NO in step 480), the lamp 11 is turned off. In order to indicate that it is time to turn on, the warning light driver 40 is controlled to flash the warning light 45 (step 490).

Subsequently, the microcomputer 30 determines whether the current illuminance is suddenly changed. If the current illuminance is rapidly changed (YES in step 500), the microcomputer 30 proceeds to the step 440 to perform the corresponding step and subsequent operations. On the other hand, if the current illuminance does not change rapidly (NO in step 500), the flashing operation of the currently flashing warning light 45 is released (step 510). Here, the method for determining the illumination intensity change has already been described in the description of the operation of the microcomputer 30.

According to the present invention as described above, by adaptively responding to the ambient illuminance to determine whether the lamp is turned on / off and automatically warn, not only do not have unnecessary lamp lights, the lamp can be performed at the appropriate lighting time Will be in.
