The present invention relates to a lighting device, and in particular, by mounting a plurality of R, G, B light emitting diodes and driving circuits thereof in the lighting pipe, the user arbitrarily controls the current supplied to each group of R, G, B light emitting diodes. The present invention relates to a lighting device using a light emitting diode capable of controlling the color and luminance of light emitted through a pipe uniformly and in various ways.

In general, the illumination lamps used until now have a constant brightness in a single color.

Recently, with the development of the industry, there is a tendency to use three-wavelength lamps in order to make the lights of the lamps show almost the same state as nature.

However, even in the case of such a three-wavelength, there is no way to adjust the brightness of the light or the color of the R.G.B of the three-wavelength optimally or to taste according to the place of use. In addition, there were no more directing luminaires by voice combination by color, and voice combination through various colors depending on the place of use.

In order to solve such a problem, Korean Utility Model Application No. 1999-15084 proposes a lamp that can adjust the brightness and color, such a prior art as shown in Figure 1 rectifier for rectifying the current supplied to the power supply (1 ) And a ballast (3) for lighting a lamp using a power source rectified from the rectifier, and a lamp (2) consisting of two or more tubes (5) connected to the ballast and having different color temperatures. And an operation unit 9 such as an adjustment stick connected to the ballast to control the brightness and color of the lamp.

That is, in the related art, a lighting lamp is constructed using three tubes emitting R, G, and B colors as shown in the drawing, and the power applied to each of the R, G, and B tubes is only on and off, not pulse width modulation control. By doing so, approximately eight colors are arbitrarily combined.

Therefore, the conventional luminaire has used a plurality of RGB tubes to produce various colors, but this is not only by mounting a color filter in the tube to implement RGB, but also by simply turning on and off the bulb in the tube. There were limitations in implementing colors, and there was still a problem that the overall uniformity of luminance, saturation, and brightness could not be adequately provided, and that various modes of lighting, turning off, and blinking could not be provided.

Accordingly, an object of the present invention is to install a plurality of R, G, B light emitting diodes and their driving circuits in a light pipe, so that the user can arbitrarily control the current supplied to each group of R, G, B light emitting diodes. An object of the present invention is to provide a lighting device using a light emitting diode that can control and produce various colors and luminances of emitted light.

Another object of the present invention is to install a plurality of R, G, B light emitting diodes and driving circuits on one side of the lighting pipe, and install a reflecting plate on the other side of the lighting pipe and a prism film on the inner surface of the pipe. In addition, the present invention provides a lighting device using a light emitting diode that can guarantee a uniform color and brightness regardless of the position of the lighting pipe and can produce a more excellent atmosphere.

In addition, another object of the present invention is to provide a lighting device using a light emitting diode capable of producing a variety of voices according to the color of the light by outputting a variety of voices stored in the memory according to the selection of the function selection switch of the RGB light emitting diode There is.

The illumination pipe 110 is a light emitting member such as a discharge tube is synthesized and emitted to the outside by the incident RGB light, the prism film 120 is installed on the inner surface of the light pipe 110 to refracted incident light to the light pipe It is a member such as a film flowing into the 110, the reflecting plate 130 is installed on one side of the light pipe 110 to reflect the light refracted and incident light through the prism film 120, RGB light emitting diode 150 is a light emitting means which is installed on the same substrate 140 on the other side of the light pipe 110 and emits light according to power supplied from the outside to emit light of various colors into the light pipe 110. The controller 160 controls the RGB light emitting diodes 150 for each of the RGB colors, and according to a user's selection, the controller 160 controls whether or not the voice selection and the RGB light emitting diodes 150 are turned on or off and the on / off time by a program pre-stored in the memory. Individual control It is made to.

That is, the prism film 120 is inserted into and mounted on the inner surface of the cylindrical light pipe 110 having both sides open, and the RGB light emitting diode 150 and the controller 160 are mounted on one side of the open light pipe 110. Is installed on the PCB board, and the reflecting plate 130 is installed on the other side thereof, thereby controlling the power input for each color group of the RGB light emitting diodes 150 through the controller 160. It is a lighting device that can produce combined RGB light.

FIG. 3A illustrates an arrangement example of the RGB light emitting diode 150 according to an embodiment of the present invention, and FIG. 3B illustrates an electrical connection state of FIG. 3A.

As shown in the figure, by using a plurality of RGB light emitting diodes 150 are mixed in a matrix form on the same PCB substrate 140 and arranged in a substantially hexagonal shape. Of course, it may be arranged in a lozenge or circular shape.

The RGB light emitting diodes 150 are provided in series and parallel for each color as shown in FIG. 3B. Since the voltages required for each color are different, that is, R is 1.72V, G is 3.22V, and B is 3.16V. The number and matrix of each of the RGB light emitting diodes 150 connected in series / parallel are different. For example, when a voltage of DC 24V is applied, 27 red (R) LEDs 151 are installed in a 9 × 3 matrix, and 25 green (G) LEDs 153 are installed in a 5 × 5 matrix. In addition, 25 blue (B) light emitting diodes 155 are provided in a 5 x 5 matrix.

Accordingly, the RGB light emitting diodes 150 are controlled in the same manner for each of the R, G, and B groups 151, 153, and 155.

4 is a circuit diagram showing a detailed configuration of a controller according to an embodiment of the present invention, a memory 161, an input switch unit 165, a control unit 171, an output switch unit 173, a reset switch 175 ), A voice signal processor 178 and a power supply unit (181, 185).

The memory 161 is composed of various control programs for controlling the lighting and turning off of the RGB light emitting diodes 150, and ROMs and RAMs containing various voice data such as birds sounds. Selected.

The input switch unit 165 may include a plurality of timing switches 166 for collectively selecting on and off timing cycles of the RGB light emitting diodes 150, and a light emitting diode 150 of a specific color among the RGB light emitting diodes 150. A plurality of light emitting diode selection switches 167 for selecting whether to turn on and off, and a plurality of function selection switches 168 for selecting a cycle of on and off for each color of the RGB light emitting diodes 150.

The control means 171 receives a signal input from the plurality of timing switches 166, the light emitting diode selection switch 167, or the function selection switch 168, and then determines a corresponding control program and a voice. And outputs a pulse width modulation control signal to the RGB light emitting diode 150 and converts audio data read from the memory 161 into an analog signal.

The output switch unit 173 has a current path connected between the LED groups 151, 153 and 155 for each color of the RGB LED 150 and the ground voltage, and according to the output voltage of the control means 171. It is composed of switching means (Q1, Q2, Q3) is opened and closed to supply power to the LED group 150 for each color.

The reset switch 175 is a switch for initializing the control of the RGB light emitting diode 150. Whenever the reset switch 175 is input, the control means 171 confirms the selection of the input switch 165 again and A corresponding program is read from the memory 161 to control lighting of each RGB light emitting diode 150.

In addition, when a specific switch of the input switch 165 is turned off, the voice signal processing unit 178 reads the characteristic voice data from the memory 161 and outputs it through the control means 171 to convert the signal into a voice signal. After the speaker 179 is made to output.

In addition, the power supply units 181 and 185 receive the AC 220V power input from the outside, convert the power into a predetermined DC voltage, and then supply the power to the RGB light emitting diodes 150. The DC / DC converter 185 converts the DC voltage converted through the step 181 to a predetermined level and supplies it to the controller 160.

In addition, reference numeral 177 is an oscillator for generating a timing clock signal.

Looking at the operation of the lighting device configured as described above as follows.

The input switches 165 are made of dip switches. When the switches are turned on with the timing switches 166 from 1 to 6, the timings of turning on and off the LEDs 150 are faster, and timing switches When 166 is less on, the light-emitting diode 150 is turned on and off. That is, the pulse width for controlling the output switch unit 173 is variable according to the setting of the timing switch 166. When the pulse width output from the control means 171 is long, the RGB light emitting diode 150 is turned on and off. When the timing is slow and the pulse width is short, the timing of turning on and turning off is faster.

In addition, the light emitting diode selection switch 167 is provided with three from the seventh to the ninth. If the seventh switch is off, the control means 171 does not turn on the first switching means Q1. The red (R) light emitting diodes 151 are not turned on, and therefore, the lighting device does not perform color synthesis according to the red color. Therefore, the LED selection switch 167 can be arbitrarily adjusted to extract the synthesis of a specific color.

In addition, the function selection switch 168 is provided with three to 10 to 12, which is to specify the time of turning on and off each of the RGB LEDs 150, depending on the switch selection of the various modes of lighting, off and Can produce flashing.

The control program of each of the RGB light emitting diodes 150 according to the selection of the input switch 165 is set in advance in the memory 161. The control means 171 in accordance with the selection of the input switch 165 is the memory 161. After storing the control program stored in the ROM in the RAM to control each output switch unit 173 according to the program.

Therefore, the control means 171 analyzes the input switch 165 whenever the reset switch 175 is input, reads the corresponding program from the memory 161 and controls the output switch 173, respectively.

In this manner, each of the RGB LEDs 150 is controlled, and the light emitted from the LEDs 150 is refracted by the prism film 120 installed on the inner surface of the light pipe 110 and installed on the other side ( 130, the light reaching the reflector 130 is reflected and flows back to the light emitting diode 150, so that the light pipe 110 emits light having a constant and high luminance regardless of the position.

If the prism film 120 or the reflecting plate 130 is not present in the light pipe 110, the periphery of the light emitting diode 150 and the opposite area to which the light reaches are exceptionally bright compared to other parts and thus have irregular brightness as a whole. Since light leaks from each part of the pipe 110 to the outside, the overall brightness is somewhat dark.

As described above, the lighting device according to the present invention can properly control the lighting and turning off of the plurality of RGB light emitting diodes 150 through the output switch 173, thereby synthesizing the RGB colors, respectively, to provide 256 different colors of high brightness. In addition, the user can arbitrarily set the color change, the specific monochromatic light, and the light emission mode according to the selection of the input switch, so that the user can freely implement the lighting of the desired color and the speaker when the specific switch is selected (off) Through the sound of nature such as birds, water, animal sounds can be output to create an excellent atmosphere.

In this way, when the lighting device using the RGB light emitting diode 150 is structurally changed, the bridge lighting lamp, the interior lighting lamp, the spot lamp, the landscape lamp, the tree lamp, the induction lamp, the floodlight, the landfill lamp, It can be applied and used in the garden.

Therefore, although specific embodiments of the present invention have been described and illustrated above, it will be apparent that the present invention may be variously modified and implemented by those skilled in the art. It should not be understood individually from, but should fall within the claims appended to the present invention.

Therefore, in the present invention, by mounting a plurality of R, G, B light emitting diodes and their driving circuits in the lighting pipe, the user can arbitrarily control the current supplied to each group of R, G, B light emitting diodes to be emitted through the light pipe. In addition to selecting and adjusting the color, brightness, and voice of the light, it is possible to produce a variety of colors, and reflectors are installed on the other side of the light pipe, and prism films are installed on the inside of the light pipe. And there is an advantage that can guarantee the brightness and create a more excellent atmosphere.
