Description

Illumination control device for lamps {APPARATUS FOR CONTROLLING INTENSITY OF ILLUMINATION IN A LAMP}

The present invention relates to a lighting lamp, and more particularly, to an illuminance control device for a lighting lamp using a dimmer method that gradually dims up or dims down lights while pressing a command button when adjusting the illuminance of the lighting. .

In general, homes and offices use desk lamps such as fluorescent lamps, incandescent lamps, and indoor lamps, and the lamps are provided with a power switch for turning on / off a load.

The lamps can be turned on / off by using the power switch, but it is impossible to adjust the illumination at user's discretion. For example, to turn on the lamp for bedtime at bedtime, a separate bed lamp or a bedside stand must be purchased. There was an inconvenience.

Recently, a lighting lamp that can adjust the lighting to several levels of illumination according to the demand of the consumer has been released, but the user selects one of the upper, middle, and lower illuminance in a state where the illumination is already set in advance. There is a problem that is quite inefficient because it is not a random adjustment to the desired intensity.

Therefore, the purpose of the present invention is to adjust the illumination of the illumination by gradually dim up (Dim Up) or dim down the illumination while pressing the command button, the illumination control for the illumination that can be precisely adjusted to the desired illumination To provide a device.

The rectifier circuit unit 120 includes rectifier elements such as capacitors C1 and C2, resistors R2, and diodes D1 and ZD for converting an input AC power into a predetermined DC power. It is configured to convert the input 220V AC power into approximately 5V DC power to supply operating power for various control circuits.

The dim-up adjusting unit 140 is to increase the illuminance of the load 110 arbitrarily by the user, and provides a direct current power source according to the dim-up switch SW1 for manually opening and closing the current path and the on / off of the dim-up switch SW1. When the dim-up switch SW1 is turned on, the first transistor Q1 is turned on, and DC power is applied to the control unit 180. The dim-down adjusting unit 150 is configured. In order to gradually lower the illuminance of the load 110 arbitrarily by the user, a dim down switch SW2 for manually opening or closing a current path and a DC power supply according to on / off of the dim down switch SW2 are opened and closed. The second transistor Q2 is configured to operate. When the dim down switch SW2 is turned on, the second transistor Q2 is turned on so that the DC power is applied to the control means 180.

The load driving unit 160 is configured to adjust the point / light off and illuminance of the load 110 by controlling the frequency of the AC power AC1 and AC2 supplied to the load 110 according to a predetermined lighting control signal. A photocoupler PC1 composed of a light emitting diode PD1 and a die solution DIAC in response to a control signal output from the means 180 and an output signal of the photocoupler PC1 are opened and closed to determine an input AC power source. It consists of the triac element TRIAC which converts into a frequency, and supplies it to the load 110, and the filter R3, C3 etc. which remove a high frequency noise.

In addition, the load detection unit 170 is connected to the AC power input terminals (AC1, AC2) applied to the load driver 160, respectively, the current path is connected and detects the power flowing through the load 110, the control means 180 It consists of a photocoupler (PC2) consisting of a bi-directional light emitting diode (PD2) and the phototransistor (PT) applied to detect the attachment or detachment of the load 110 and outputs a corresponding detachment signal to the control means 180.

It is configured to gradually control the illuminance of the load 110. That is, while pressing the dim-up switch SW1 or the dim-down switch SW2, the illumination is dim-up or dim-down by adjusting the frequency of the AC power supplied to the load 110 to gradually change the illuminance.

In addition, the control means 180 is mutually insulated from the load driver 160 and the load detector 170 through the photo coupler (PC1, PC2), so as to protect the control means 180 from the input surge voltage or various noise do.

Looking at the operation of the present invention configured as shown in Figures 1 and 2 as follows.

First, the load detection unit 170 detects whether the load 110 is mounted on the electric socket and outputs it to the control unit 180 through the photocoupler PC2, and the control unit 180 is provided from the load detection unit 170. When the load detection signal is output, it is possible to control the on / off and dim up or dim down of the load 110.

Subsequently, when the load 110 is worn, the control unit 180 determines whether a signal input from the outside, that is, a dot / light off signal or a signal for adjusting the illuminance of the illumination, respectively.

When the input signal is a lighting signal input from the power switch 130, the control means 180 operates the photocoupler PC1 of the load driver 160 to turn on the triac TRIAC, and the triac TRIAC. By supplying a predetermined AC power through) to turn on the load (110).

On the other hand, when the input signal is a signal input from the dim-up adjusting unit 140, the control means 180 selects the photocoupler (PC1) of the load driving unit 160 during the time for pressing the dim-up switch (SW1) of the dim-up adjusting unit 140. The triac (TRIAC) is controlled by varying the frequency of the load, while gradually increasing the frequency of the AC power supplied to the load 110 during the time when the dim-up switch SW1 of the dim-up control unit 140 is pressed. ) Will gradually increase the illuminance.

In addition, when the input signal is a signal input from the dim down adjustment unit 150, the control means 180 is a photo coupler (PC1) of the load driver 160 during the time for pressing the dim down switch (SW2) of the dim down adjustment unit 150 ) Is controlled to a predetermined frequency to control the triac (TRIAC), while gradually decreasing the frequency of the AC power supplied to the load 110 while the dim down switch (SW2) is pressed down of the load 110 The illuminance will gradually decrease.

As such, the brightness desired by the user is arbitrarily adjusted by controlling the illuminance of the load 110 by the variable frequency control of the 60 Hz AC power supplied to the load 110 during the time when the dim up switch SW1 and the dim down switch SW2 are pressed. Can be adjusted freely.

When the load 110 is turned on, when the extinguished signal is input from the outside, that is, when the input signal is the extinguished signal input from the power switch 130, the control means 180 controls the port of the load driver 160. The load 110 is turned off by turning off the coupler PC1 to cut off the AC power supplied through the triac TRIAC.

Accordingly, in the present invention, when the illumination button is adjusted, the lighting is gradually dim up or dim down while the command button is pressed, so that the user desires according to various usage purposes such as learning or sleeping. It is precisely adjustable in illumination, and can be used for various purposes as a single lamp, which is a very economical and efficient advantage.
