Description

Illumination automatic control device of LED lighting device

The present invention relates to an automatic illumination control device, and more particularly to an automatic illumination control device for use in the LED lamp.

Conventionally, incandescent lamps and fluorescent lamps are mainly used as lighting devices. However, incandescent lamps and fluorescent lamps consume more power than lighting efficiency, and they use about 2.1 trillion kWh of electricity in the world. This amounts to 12-15% of the total electricity, which generates 1.7 billion tons of CO ₂ annually. In addition, since fluorescent lamps are manufactured using mercury, and lamps have a short lifespan, they need to be replaced frequently, so if they cannot be collected and disposed of properly, environmental pollution problems are also serious. Due to these problems, environmental regulations are being strengthened around the world recently, with some countries prohibiting the sale of incandescent and fluorescent lamps.

Recently, the lighting using the energy-saving and eco-friendly LED (light-emitting diode) has been in the spotlight. This LED lighting has a long life, high brightness, and low power consumption, thereby saving energy. If 30% of domestic lighting is replaced by LED lighting by 2015, it is well known that it has an effect of reducing power of about 16 billion mAh and reducing 6.8 million tons of CO ₂ every year.

In addition, LED lamp is considered as a means to replace the downlight lighting (illumination adjustable lighting), which was implemented as incandescent, halogen lamps in the traditional lighting.

The current LED lighting is configured by replacing the lamp with the LED lamp 14 in the lighting switch 11, lighting wiring 12 and the socket 13 used in the existing incandescent or fluorescent lamp as shown in FIG. Such LED lighting can control only the on / off of the LED lamp 14 using the light switch 11 used in the prior art, and cannot control the illuminance thereof.

That is, the LED light 24 is controlled on / off using the light switch 11, and the illuminance of the LED lamp 24 is controlled using the light control switch 21. Then, the controller 23 receives the on / off control of the illumination switch 11 and the illumination control of the illumination control switch 21 to drive the LED lamp 24.

Such conventional illumination controllable LED lighting has a problem in that the installation is complicated and expensive because additional wiring work must be performed separately from the existing lighting wiring 12.

The present invention has been proposed to solve the above problems, and an object of the present invention is to provide an apparatus for the user to emotionally control the lighting of the LED lamp by using an electronic switch for illumination control.

In order to achieve the above object, the automatic illuminance control device of the LED lighting apparatus according to an embodiment of the present invention, an electronic switch for dimming control to output a pattern signal consisting of supply or interruption of the AC input power supplied to the LED lamp ; And an LED lamp controller for analyzing the pattern signal and controlling the illuminance of the LED lamp according to the analyzed pattern signal.

According to the present invention as described above, when the user emotionally controls the LED lighting by using the electronic switch for illuminance control, the electronic switch for illuminance control sends a predetermined pattern to the LED lamp control device, and the LED lamp control device inputs the pattern. Since the user can implement the emotional lighting requested and interpreted by the user, the user's emotional lighting can be easily controlled.

Applicant of the present invention has applied for a LED lighting system that can control the on / off and illuminance of the LED lamp as a 2009-0110113 to the Korean Patent Office.

3 is a functional block diagram illustrating an illumination controllable LED lighting system disclosed in Patent Application No. 2009-0110113. The illumination controllable LED illumination system disclosed in this prior patent application consists of the illumination switch 11, the illumination wiring 12, the LED lamp control apparatus 30, and the LED lamp 24. As shown in FIG.

The LED lamp control device 30 includes an AC / DC converter unit 31, on / off detection means for detecting on and off states of a light switch, and an on / off state of the light switch from the on / off detection means. A dimming judging means for outputting a dimming signal by determining the snapping operation of the light switch by receiving information, a dimming adjusting means for adjusting the illuminance of an LED lamp when a dimming signal is input from the dimming judging means, and A power holding circuit unit 42 for supplying driving power to the LED lamp during a snapping operation, and receiving off state information of the light switch from the on / off detecting means, when the off state of the light switch exceeds a threshold time. And power off means for turning off the LED lamp.

The lighting switch 11 is connected in series to the AC power through the lighting wiring 12 to supply or cut off the AC power to the LED lamp 24. When the user turns off the light switch 11 for a while and then turns it on again, that is, when the user turns off and then on again (this is called snapping), the LED lamp controller 30 controls the dimming control. Recognize it as a signal.

The on / off detecting means includes a zero cross detector unit 32, an undetected counter unit 33, and a clock 34. The dimming determination means includes a storage unit 41, a first comparator 39 and a dimming determination unit 37. The power-off means includes a storage 41, a second comparator 40 and a power-off judging 38. The dimming adjusting means includes a dimming step counter unit 36 and a dimming adjusting unit 35. Detailed configuration description and operation description of the LED lamp control device 30 refer to the application specification of the prior patent application No. 2009-0110113.

In the illumination controllable LED lighting system disclosed in prior patent application No. 2009-0110113, the LED lamp 24 is turned on at the maximum brightness when the user turns on the light switch 11. When the LED lamp 24 is turned on (on), when the lighting switch 11 is turned off (off) for a short time (dimming threshold time) and turned on (on), the illumination of the LED lamp is adjusted by one step. If the user stops working at the desired brightness, the state is maintained. If a certain time elapses after the user turns off the light switch, all operations are reset and the LED lamp is turned off.

That is, in the illumination controllable LED lighting system disclosed in the prior patent application No. 2009-0110113, in order for the user to dim the illumination step by step, the user should turn off the light switch 11 for a while. At this time, the off time should be longer than the dimming threshold time and shorter than the power off determination time. If the off time is shorter than the dimming threshold time, the dimming control is not performed. If the off time is longer than the power off determination time, the LED lamp is turned off.

Dimming control of the LED lamp using the light switch 11 is difficult to use the dimming function because the user has to snap longer than the dimming threshold time and shorter than the power off determination time. In addition, the user can only dimm the illuminance step by step and cannot control the emotional lighting.

The present invention is an improved technology of the prior patent application No. 2009-0110113, which allows the user to emotionally control the illuminance and color temperature of the LED lamp and adds a dimming control electronic switch for outputting a pattern according to the user's sensitivity control, LED The lamp controller is configured to interpret the pattern to control the LED lamp. Here, the emotional control means that the intensity of the warm tone or cool tone is adjusted, or a predetermined mode (one of the repair mode, the reading mode, the rest mode and the sleep mode) is selected to control the LED lamp. It means controlling the illuminance and color temperature.

The automatic illuminance control device of the LED lighting apparatus according to the present invention includes an electronic switch 410 for dimming control that outputs a pattern signal according to a user's operation, and receives and interprets the pattern signal, and the LED lamp 24 according to the pattern signal. It is roughly divided into the LED lamp control device 420 to adjust and control the.

The dimming control electronic switch 410 detects an operation state of the dimming control input unit 411 including an emotion control item manipulated by a user and the dimming control input unit 411 by a user, and outputs a pattern signal accordingly. Electronic control to switch between the AC input power and the LED lamp control unit 420 according to the control unit 412 and the pattern signal output from the control unit 412 to transmit the pattern signal to the LED lamp control unit 420 The switch 413 and a power supply unit 414 for generating a driving power from the AC input power supply to the internal components of the dimming control electronic switch 410. The controller 412 displays the current LED lamp on / off state, dimming level, emotional lighting state, and the like on the display unit 415. The dimming control electronic switch 410 may be implemented as a 3-wire switch or a 2-wire clockcon switch.

As shown in FIG. 5, the dimming control input unit 411 includes a warm tone control switch 51 for up / down control of warm tones and a cool tone control switch for up / down control of cool tones. 52) and an on / off switch 53 for on / off control of the LED lamp.

The LED lamp control device 420 includes an AC / DC converter unit 421 for converting AC input power into DC power, a zero potential detector 422 for detecting zero potential from the AC input power, and a pattern signal. The pattern storage unit 423 for storing the LED lamp control information, and recognizes the AC input power supply section and the AC input power cutoff section from the detected zero potential information to receive a pulse signal input from the dimming control electronic switch 410 A control unit 424 for analyzing and applying the analyzed pulse signal to the pattern storage unit 423 to query the LED lamp control information corresponding to the analyzed pulse signal and to output the LED lamp control signal according to the LED lamp control information. And controlling the supply amount of DC power between the AC / DC converter unit 421 and the LED lamp 24 according to the LED lamp control signal. Dimming control unit for adjusting the degree 425 and the power holding circuit unit for supplying the driving power to each component of the LED lamp control device 420 while the dimming control electronic switch 410 cuts off the AC input power ( 426).

The zero potential detector 422 detects a point where the AC input power becomes zero potential. That is, the zero potential detector 422 becomes a non-active level (high or low) when the AC input power is not zero potential, and becomes an active level (low or high) when the AC input power becomes zero potential. While the AC input power is normally supplied, it detects the zero potential intermittently and periodically, and then transitions from the non-active level to the active level periodically, and continuously detects the zero potential and maintains the active level while the AC input power is cut off. . The zero potential detector 422 inputs the zero potential detection signal to the controller 424.

If the zero potential detection signal maintains the non-active level and then transitions to the active level intermittently and periodically, the controller 424 recognizes the AC input power supply section in which the AC input power is normally input, and the zero potential detection signal maintains the active level. If the AC input power is cut off, it is recognized as the AC input power cutoff section. The pattern signal is recognized from the combination or the holding time of the AC input power supply section and the AC input power cutoff section.

The operating method of the automatic illumination control device of the LED lighting apparatus according to the present invention is as follows.

When the user operates the on / off switch 53 of the dimming control input unit 411 and switches on, the controller 412 recognizes this and drives the electronic switch 413 so that the AC input power is the LED lamp control device 420. To be supplied.

When the AC input power is normally supplied, the zero potential detector 422 outputs a zero potential detection signal that maintains the non-active level and then transitions to the active level intermittently and periodically, and the control unit 424 receives the AC from the zero potential detection signal. By recognizing that the input power is normally supplied and controlling the dimming control unit 425, the DC power of the AC / DC converter unit 421 is supplied to the LED lamp 24.

When the user adjusts the emotional lighting of the dimming control input unit 411, for example, when the user presses the warm tone up or down of the worm tone control switch 51 or the cool tone up or down of the cool tone control switch 52, the controller 412 controls the sensitivity. Recognize and generate pattern signal according to the emotional lighting control. The pattern signal is a signal formed by supplying / blocking AC input power, and the controller 412 controls the electronic switch 413 according to the pattern signal to supply or supply AC input power supplied to the LED lamp control device 420. Block it.

When the AC input power supplied to the LED lamp control device 420 is cut off, since the zero potential detector 422 maintains the zero potential detection signal at the active level, the control unit 424 receives the AC input from the zero potential detection signal. Know the power off section. On the other hand, when AC input power is again supplied to the LED lamp control device 420 according to the pattern signal, since the zero potential detector 422 outputs a zero potential detection signal that periodically transitions from the non-active level to the active level, The controller 424 recognizes the AC input power supply section from the zero potential detection signal.

The control unit recognizes the pattern signal output from the dimming control electronic switch 410 from the holding time or combination of the AC input power cutoff section and the AC input power supply section, and applies the recognized pattern signal to the pattern storage unit 423. The LED lamp control information is inquired, and the dimming control unit 425 is controlled according to the inquired LED lamp control information to control the illumination of the LED lamp. For example, when the user increases the worm tone, the dimming control electronic switch 410 outputs a pattern signal accordingly, and the LED lamp controller 420 interprets the pattern signal to brightly control the illumination of the LED lamp for increasing the worm tone. .
