Description

LED lighting system using multi-channel output controller {Lighting system of LED using output controller of plural channel}

The present invention relates to an LED lighting system that sequentially flashes LEDs using a controller that outputs multiple channels, such as a conventional RGB controller.

Light Emitting Diodes (LEDs) are emerging as next-generation lighting sources due to their diverse color expressiveness, excellent power efficiency, low power consumption and semi-permanent lifespan.In particular, RGB LEDs are red, green and blue. (Blue) LED chips can be used for lighting and advertisement because they can realize various colors by changing the light intensity of each chip.

RGB LED lighting is generally marketed as a standardized LED module. At this time, the LED module is a LED package including a red LED chip for emitting red light, a green LED chip for emitting green light, a blue LED chip for emitting blue light and a reflector, and the like, as is known. The circuit board is formed of an electric element and a circuit for driving the LED packages by installing the LED packages thereon.

It also has three channels, R, G, and B channels to make these LED modules blink, and an RGB controller that causes the LED module to emit light in R, G, and B colors when the lighting signal of each channel is output. Is used.

In general, the RGB controller is used to control the color emitted from the LED modules. The LED modules are connected to all of the R, G, and B channel lines drawn from the RGB controller. In the RED color, when the G channel line is activated, all of the LED modules are displayed in the GREEN color, and when the B channel line is activated, the blue color is displayed.

However, in order to increase the advertising effect while focusing attention on LED boards installed in billboards, a lighting method is needed in which LED modules arranged in a row are blinking in sequence, but it is achieved by a wiring method and a controller control method of connecting conventional RGB controllers and LED modules. Difficult to do

Conventionally, in order to sequentially flash LED modules, a digital multiplex (DMX) control scheme has been studied and actually applied.

The conventional DMX control method is composed of a DMX controller for generating a DMX control signal, and an LED module in which an address, which is a unique address, is set. At this time, the DMX controller and LED modules are connected to a power line and RGB channel lines and a communication line which is a path through which data is moved.

The DMX controller stores the address address of each of the LED modules and the lighting sequence of the preset LED modules. When the power is applied, the DMX controller transmits a packet including an address address and color data codes to the LED module, and the LED module receives the received packet. If the address of the address matches the address assigned to the LED chip corresponding to the color information of the data code is configured to emit light by modifying the lighting order of the LED modules to increase the advertising efficiency.

That is, the conventional DMX control method transmits a packet to the LED module according to a preset lighting and blinking sequence, and the LED modules control lighting by receiving a data code of the packet.

However, in the conventional DMX control method, since the DMX controller stores the lighting order and the address address of each of the LED modules and generates a packet in accordance with the stored lighting order and transmits the packets to the LED modules, the controller must be separately configured, and the LED module In addition, since a data communication receiver capable of receiving a packet must be equipped, a problem arises in that the manufacturing and installation costs increase.

In general, since the LED module includes electric elements and circuits and does not include a separate data communication receiver, in order to apply the conventional DMX control method, the entire LED modules need to be replaced because they are not linked to the installed LED modules. The manufacturing and installation costs will be further increased.

In Korean Patent Application Publication No. 10-2012-0076759 (name: method for generating reference list of lighting control device and lighting control device), coordinates and numbers of lighting devices are prepared as a reference list in advance and inputted to the coordinates of the input lighting device. A lighting control apparatus capable of controlling lighting by newly creating a reference list when a configuration or arrangement of an lighting apparatus is changed by emitting light previously stored color data of corresponding signal coordinates is described.

However, the lighting control device, like the conventional DMX control method, must be provided with a controller including a separate memory, and the memory address of each of the LED modules must be allocated and stored, so that the manufacturing and installation cost does not solve the problem. can not do it.

In addition, since the lighting control device does not interlock with pre-installed LED modules that are not provided with a data communication function, the conventional problem of replacing not only the controller but the entire LED modules continues.

An object of the present invention to solve the problem is to use a controller for outputting a drive signal of a plurality of channels that can be sequentially flashing the LED light through a simple wiring operation can be linked to the LED module that does not support the data communication function To provide an LED lighting system.

In addition, another object of the present invention is to provide a LED lighting system to perform a specific flashing operation such as a sequential flashing light by operating the connected LED module when a drive signal is input to the channel line connected to each LED module is connected to one channel line It is to provide.

In addition, another solution of the present invention is to provide an LED lighting system that can reduce the installation and manufacturing costs because the LED lighting can be controlled by a simple wiring operation of the RGB controller and LED modules without replacing the equipment.

Solution to Problem The present invention for solving the above problems is at least one LED module connected to each of the plurality of channel lines; And a controller for lighting the LED modules connected to the channel line to which the channel signal is supplied by outputting a channel signal to the channel lines, wherein the controller is different from a point at which the channel signal is supplied to one of the channel lines. By differently supplying the channel signals to the lines, the time at which the LED modules connected to the one channel line are turned on and the time at which the LED modules connected to the other channel lines are turned on are formed differently.

In the present invention, it is preferable that the controller sequentially outputs a channel signal to the channel line so that the LED modules connected to the channel lines flash sequentially.

In the present invention, the channel lines are three, and it is preferable that the controller sequentially outputs channel signals of 1/3 cycles to the channel lines.

In addition, the LED module in the present invention; At least one LED package installed inside the enclosure and including at least one LED chip is installed, and is connected to one terminal of the LED chip and connected to a power line, and connected to the other terminal of the LED chip. However, it is preferable to include a circuit board on which channel connection parts connected to one of the channel lines are formed.

In addition, in the present invention, the channel lines penetrate the lower portion of the circuit board of the housing, the power connection portion of the channel connection portion is provided directly above the power line, the channel connection portions are provided directly above the channel lines, Preferably, one of the channel connecting portions is connected to one of the channel lines in the connecting member.

In addition, in the present invention, the housing is preferably any one of a cube type or a bar type.

In the present invention, the controller is preferably an RGB controller for outputting a red channel signal, a green channel signal and a blue channel signal to each of the channel lines.

In the present invention, it is preferable that the LED modules are lit in white or monochromatic colors.

According to the present invention having the above-mentioned problems and solutions, the controller can be easily installed because the LED lights can be sequentially flashed through simple wiring without using data communication with the LED modules.

In addition, according to the present invention, not only a separate controller is provided in the controller, but also the installation and manufacturing costs are reduced because the LED modules do not need to be equipped with a data communication receiver such as an address receiver.

In addition, according to the present invention, the installation cost is further reduced by interworking with LED modules that do not support data communication.
