Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an AC direct control type control board capable of controlling dimming and lighting of an LED lamp,

The present invention relates to a microwave sensor (50); Setting switch 40; A timer 11; When the microwave sensor 50 senses a human body, generates a pulse width control signal in accordance with the on-off and dimming conditions set by the setting switch 40 and the set time of the timer 11 and outputs the pulse width control signal to the first constant- 20 to the microcomputer 30; And a rectifying part (10) connected to a general AC power source,

The first constant current unit 20 generates a constant current waveform by receiving a DC voltage from the rectifying unit 10 and generates an on-off or dimming current signal by combining the pulse width control signal with the constant current waveform, And an on-off or dimming current signal is transmitted to the DC voltage providing line provided to the LED lamp in the rectifying unit (10). The present invention relates to an AC direct control type control board .

In general, a fluorescent lamp used in a house or an office is a structure in which two lamps and a ballast are connected (see FIG. 1), and a 32W fluorescent lamp and a second lamp are structured such that two 32W fluorescent lamps are turned on at a time. Here, the ballast serves to prevent the current from being increased because the lamp may be broken if the current in the fluorescent lamp is excessively increased.

Unlike a fluorescent lamp, an LED lamp receives an AC power and converts it to a direct current (refer to FIG. 2). All LED lamps are turned on by using one AC / DC converter.

However, LED lamps consume 80% of light and 20% of heat due to the nature of LED, but fluorescent lamp consumes 20% of light and 80% of heat, Of course it is good. For example, it is well known that the brightness of a 17 ~ 18W LED lamp is better than the brightness of a 32W fluorescent lamp, and the lifetime of the LED chip is much longer than the life of the lamp.

Meanwhile, LED makers have been adding dimming or spotlighting capabilities to the lighting fixtures using sensors to target energy-saving LED lighting fixtures. That is, 100% lighting is performed when an object such as a person or an automobile is detected by using a dimming converter or a light-up converter in addition to the sensor. When the object is not present, the light is turned off or dimmed (for example, 20% We have tried to extend the lifetime of LED lighting as well as saving.

However, conventionally, by using a dimming or flashlight converter separately, it has become a LED lamp that is driven only by dimming or lighting.

In addition, if many LED manufacturers enter the LED lighting market, if the manufacturer of the LED lighting lamp selected by the consumer is shut down, there is a possibility that the LED lighting lamp should be completely replaced when the converter or the dimmer or flashlight converter fails. have.

In addition, various sensors for detecting a human body have been employed in lamps controlled by dimming or turning on or off according to the presence or absence of human motion detection, for example, an infrared sensor and an ultrasonic sensor.

However, the infrared sensor has a disadvantage in that it can not be detected unless the user's operation is large. In the infrared sensor and the ultrasonic sensor, when the sensor is installed inside the lamp cover, the sensor can not detect the human body by the cover.

Therefore, the infrared sensor and the ultrasonic sensor can not be integrated with the lamp, and the infrared sensor and the ultrasonic sensor are separately exposed to the side or periphery of the lamp.

In summary, the inventor of the present invention has proposed a control board which collects a function of rectifying an alternating current into a direct current, a function of implementing dimming or lighting using a microcomputer and a constant current section, and a function of supplying sufficient power to the LED element by using a constant current section The inventors of the present invention have determined that the cost can be reduced because it is not necessary to separately use the point light or the dimming converter.

In addition, by using a microwave sensor, it is possible to sense more precisely by using an infrared sensor or an ultrasonic sensor, and furthermore, it is integrated into an LED control board. However, if only the main part of the antenna is exposed, It is possible to reduce the space required for the present invention. (See Patent Registration No. 10-1448962 filed by the present applicant)

In addition, if a single control board is configured to send dimming or on-off signals to two LED boards, both the LED lamps can be lighted or dimmed or, alternatively, Dimming control, thereby making it possible to broaden the choice of the consumer and save energy.

6 is a diagram illustrating an example of a remote controller interface used in an AC direct control type control board capable of controlling dimming and lighting of an LED lamp according to the present invention.

The lighting system using the direct current control board 100 according to the present invention is configured to send a dimming or on / off signal to one or two LED boards by one control board 100.

That is, one control board 100 included in the first LED lamp is configured to control the first LED lamp and the second LED lamp.

Here, the interval between the first LED lamp and the second LED lamp may be several meters as well as the same interval as the second-order fluorescent lamp, and preferably a microwave sensor 50 integrally provided on the control board 100, So that two LED lamps can be installed according to the detection range of the LED.

In addition, the LED lamp control board 100 according to the present invention does not use the dimming converter and the light-up converter, but merely dimly connects the first LED substrate and the second LED substrate by organic coupling between the microcomputer 30 and the constant- Signal or a light-off signal.

In the present invention, the microwave sensor is built in the control board 100, and the sensor signal is supplied to the microcomputer 30 and the first constant current The dimming and the lighting can be implemented using the functional combination of the unit 20.

Also, the LED lamp control board 100 according to the present invention is integrally connected to the control board 100 so that each component can occupy a minimum space inside the LED lamp.

Preferably, when the types of components are collected by the IC chip, the IC chip may be configured to be embedded in the board.

The control board 100 is integrally formed by including a rectifying section 10, a timer 11, a first constant current section 20, a microcomputer 30, a setting switch 40 and a microwave sensor 50, The illuminance sensor 12 may be further included according to the design conditions.

The rectifying unit 10 receives an AC power and converts the AC power to a DC power to provide a DC voltage to the first constant current unit 20. The rectifying unit 10 preferably supplies power to the first LED substrate and the second LED substrate, It is designed to provide DC voltage considering voltage drop due to wire connection to LED board.

Referring to FIG. 5, first and second connectors 61 and 62 are included to provide power to the first LED substrate and the second LED substrate.

Depending on the design conditions, it is possible to provide power only to the first LED substrate, and in this case, of course, only one connector is included.

The second constant current unit 21 shown in FIGS. 4 and 5 has a configuration that can be added according to the number of LED elements included in the LED lamp, and performs a function of providing additional power when the number of LED elements is large .

That is, in the case of FIG. 4, there are many devices included in the first LED substrate, and in the case of FIG. 5, the case of providing power to two LED substrates.

The timer 11 is a component that allows the user to set the lighting time and the dimming time, and can be configured to be changed and set according to the user's operation. Depending on the design conditions, the microcomputer 30 may be provided with only the time information to make the user's operation impossible, or the microcomputer 30 may include the timer 11.

Here, the lighting time means a time when the microwave sensor 50 senses a human body (object) and lights the LED lamp 100%. The dimming time does not allow the human body (object) to be detected, For example, 10 to 20%).

Therefore, if the user's motion is not detected even after the lighting time and the dimming time, the LED lamp remains off. Of course, if the user's movement is detected while the LED lamp is off, the LED lamp will be lit at 100% brightness.

According to the design conditions, the time set in the timer 11 is a first time (100% output) for detecting the motion of the human body (object) and outputting it at the maximum, a second time 50 % Output), a third time (20% output) in which the motion of the human body (object) is not sensed, and a time (0%) for extinguishing the light.

The first constant current unit 20 performs a function of generating a constant current waveform by receiving a direct current voltage from the rectifier unit 10. The constant current is combined with the pulse width control signal of the microcomputer 30 and is converted into a pulse width modulation signal , The first connector 61 and the second LED 62 via the second connector 62 to the second LED substrate, respectively.

In addition, the first constant current unit 20 is designed such that a circuit for internally including the DC voltage delivered from the rectifier unit 10 after generating the off current signal without generating the constant current waveform is designed.

The microcomputer 30 generates a pulse width control signal based on the on-off and dimming conditions set by the setting switch 40 and the signal of the timer 11 when the microwave sensor 50 senses a human body To the first constant current unit 20. In the first constant current section 20, the pulse width control signal is combined with the constant current waveform so that a dimming or on-off current signal is generated and transmitted to the first or second LED substrate, respectively.

The microcomputer 30 also has a function of causing the first constant current unit 20 to operate if the first constant current unit 20 does not generate the constant current waveform when the microwave sensor 50 senses a human body .

The dimming or on / off current signals transmitted by the first constant current unit 20 may be transmitted equally to the first and second LED substrates or may be configured to selectively provide a dimming or on / off current signal to each LED substrate .

Further, the remote controller 400 may be configured to set the microcomputer 30 to set each LED lamp, which will be described later.

The microwave sensor 50 transmits a detection signal to the microcomputer 30 when a human body (object) is sensed.

Here, the characteristics of the microwave sensor are as follows. The microwave sensor can be used in an environment where there are poor conditions (heat, temperature, noise, humidity, airflow, dust, etc.) and there is little malfunction. It can detect up to 25 ~ 30m according to the characteristics of the antenna part, and can detect moving objects within 10m diameter of direct downward at a sensing angle of 360 °.

In addition, since glass and gypsum boards are also permeable to high frequencies, there is an advantage that they can be detected even when a lamp cover is installed, and the frequency output from the microwave sensor is known to be harmless to the human body.

That is, the microwave sensor 50 can sense a moving object within a range of 10 m in diameter with a sensing angle of 360 °, so that it can sense a wider range than a distance between a generally installed luminaire.

Accordingly, a single lamp provided with a microwave sensor can detect and detect motion including the coarse / wide range of the adjacent lamps, thereby reducing the installation cost of the lighting facility.

The setting switch 40 may be constituted by a dip switch, a rotary switch, or the like, and may be configured to set a lighting or a plurality of dimming outputs (20, 30, 60, 80% output).

It is possible to exclude the configuration of the setting switch 40 in order to make only the setting of the remote controller 200 possible according to the design conditions. It goes without saying that a configuration for communicating with the remote controller 200 is added to the microcomputer 30 when the remote controller 200 is added.

The illuminance sensor 12 detects the illuminance around the first LED lamp. The microcomputer 30 drives and controls the first constant current section 20 based on the illuminance detected by the illuminance sensor 12, and then transmits a pulse width control signal to the first and second LED substrates to generate an on-off or dimming current signal Lt; / RTI >

For example, when the first and second LED lamps are not illuminated and sufficient illumination is detected (daytime time), the first and second LED lamps are not turned on. Or to control dimming of the light emitted from the first and second LED lamps so that the sum of the detected illuminance and the illuminance due to the light emitted from the first and second LED lamps reaches the set illuminance.

That is, even if motion is detected by the microwave sensor 50, the first and second LED lamps are not turned on if the illuminance by natural light is sufficient. If natural light is not sufficient, the first and second LED lamps are turned on It can be constructed so as to be dimmed in accordance with the illuminance so as not to illuminate at a higher illuminance than necessary.

Depending on design conditions, the first and second LED lamps can be configured to be controlled in groups through an external device.

For this purpose, an individual ID (Identification) may be assigned to each microcomputer 30. The microcomputer 30 may be provided with a memory for storing an ID and a dimming program or the like. That is, the LED lamps are configured to be integrally controlled by grouping them in a predetermined group unit based on the ID assigned to the microcomputer 30. [

As a result, LED lamps grouped together can control dimming control in a group basis as well as set conditions (timer setting time, illuminance, and dimming rate) uniformly.

In contrast to the prior art, the prior art is to perform dimming or light-off control by directly using the signals of the dimming converter or the light-up converter so that the dimming converter or the light-up converter must be individually There is a disadvantage that the cost is increased and the product price is expensive.

However, according to the present invention, the dimming or on / off control program is incorporated in the microcomputer 30 and interlocked with the first constant current unit 20, thereby dimming or turning off the lamp can be integrally performed. do.

In addition, it is possible to reduce the cost by dimming or turning off the two LED lamps of 20W power consumption at the same time by a single 40W class control board 100, and the consumer can freely choose dimming or lighting depending on the use purpose.

Further, since the first LED lamp can be implemented as an on-off and the second LED lamp can be dimmed with one control board 100 having an input power of 40 W class, it is possible to save energy.

In addition, since the control board is implemented in direct connection type, there is no need to use a separate general converter, thereby reducing the cost.

6 is an example of an interface of the remote controller 200. It is possible to control the lighting time and brightness (dimming) of each LED lamp through communication with the microcomputer 30, as well as to adjust sensitivity / on / off of the microwave sensor.

Here, it can be implemented by using the flicker of the LED lamp to set each function without confusion.

First, to set the first LED lamp, when one of the time control buttons on the remote control 200 is pressed, the LED lamp blinks once and the lighting time is set. Thereafter, when one of the brightness (dimming) control buttons of the remote controller 200 is pressed, the dimming setting is performed while blinking twice.

After that, press the UNL button in the lamp setting button to make sure that the setting of the first lamp does not change during the setting of the second LED lamp while the first LED lamp keeps blinking.

After that, set the second LED lamp as if setting the first LED lamp and press the LOC button, the first LED lamp will no longer blink, but the two LED lamps will finish setting.

Here, the light-off (dimming) button among the dimming control buttons is turned off immediately after being turned on for the lighting time after the object is detected, or may be turned off at 50, 40, 30, 20, 0% ). ≪ / RTI >

When one of the sensor's sensitivity adjustment buttons is pressed, the LED lamp blinks 3 times to indicate that the setting is completed.

The ON / OFF button of the sensor is a setting for preventing the microwave sensor of the control board 100 from being operated. When the OFF button is set, the light is not illuminated or dimmed according to object detection, It is possible to use this function as a general LED illumination lamp in a field where the dimming or lighting is not automatically desired.

The above-described method of using the remote controller 200 is merely an example, and it is possible to use the remote controller 200 as a general LED lighting lamp by using the flicker of the lamp to set the time, dimming and sensor intensity without confusion, And locking the setting of the first ramp so as not to change the setting of the second ramp after setting the first ramp is a major design matter.

It goes without saying that the remote controller 200 described above can be applied to a case where the control board 100 is provided in only one lamp.

1 to 6 describe only the main points of the present invention. As far as various designs can be made within the technical scope thereof, the present invention is not limited to the configurations and functions of Figs. 1 to 6 It is self-evident that it is not limited.
