The present invention relates to a single-color multi-color warning beacon, and more particularly, a high-brightness light emitting diode (LED) having three or more primary colors (green, yellow, red) is expressed in a translucent cap and multi-colored when a signal is applied. The present invention relates to an improved multi-colored beacon, etc., which is used to selectively display work conditions such as failure, waiting, and normal when working with automation equipment and industrial machinery.

In general, LED (Light Emitting Diode) is an electric field emission phenomenon that emits light when a voltage is applied to a specific semiconductor, it is smaller than the conventional light source (light source), because the life is long, and electrical energy is converted directly to light energy It has low power and good efficiency.

In addition, recently developed high-brightness LEDs have a longer lifespan, save energy by more than 90% compared to conventional light bulbs, and do not require separate parts such as inverters, which are advantageous for product thinning and internal area efficiency. It is expected to be an alternative light source.

On the other hand, industrial beacons are installed in various machines, devices, and automation equipment used throughout the industry and used to convey the status of each task. Conventional industrial beacons are a light bulb or a general LED and a reflecting plate rotating inside a cap made of a transparent material. It is a general form to reflect the light to the outside by rotating the reflector plate provided with.

However, such a conventional warning lamp has a complicated structure and frequently causes a failure of components such as a rotating motor, and has a problem in that light bulbs have a short lifespan and a shortage of light, so that there is a low identification.

In addition, according to the international standard, when expressing the state of the automated machine by color, the existing rotating beacons are manufactured by the required number of colors and combined vertically to be composed of two or more stages, which are manufactured in a complex structure. Increasing the unit price and repeatedly using the same structure causes a waste of resources, there was also a problem in the heat generation and energy consumption of the bulb.

In order to improve this, Korean Industrial Registration No. 331416 (2003.10.17) has disclosed an "industrial high brightness LED warning light".

However, the above-described warning light has a complex structure because it must express a plurality of colors, at least three colors of at least red, green, and yellow, and takes up a lot of space because the plurality of LEDs must be arranged inside the warning light in a certain order. Since the lead wires for controlling a plurality of LEDs have to be complicatedly complicated, installation work is difficult and expensive.

The present invention has been created in order to effectively solve this problem in consideration of all the problems of the conventional warning lights as described above to provide a more efficient use environment, using a high-brightness LED that requires abundant light and requires less energy By adjusting the table, one LED can selectively control the desired color as needed, simplifying the structure of the warning light, reducing the size, ease of installation and maintenance, and reducing costs, while maintaining its original function. The main purpose is to provide a 1-color multi-colored warning light that can be performed faithfully as before.

The present invention, in order to achieve the above technical problem, is installed in or around the industrial facilities, and includes a base, a post, a body, an inner cap and an outer cap and an electronic circuit board mounted therein and mounted with at least one LED. In a warning light; The LED is characterized in that it provides a 1-color multi-color expression warning light expressing the desired color of the color stored in the color table in one LED through the signal control of the applied power.

In this case, the means for expressing a multi-color by the one LED, the signal control unit is mounted on the electronic circuit board and connected to the LED to express a predetermined color; An LED module unit mounted on the electronic circuit board and reading color data corresponding to a color to be expressed and controlling a color signal to be applied to the LED through the signal controller; An EP-ROM connected in communication with the LED module unit, mounted on the electronic circuit board, and storing color data relating to a color for expressing the LED and a program related to the control; It is also characterized in that it comprises a main control unit mounted on the electronic circuit board to control the driving of the LED module unit is driven by receiving a signal from an industrial facility or an operator.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment according to the present invention.

Prior to the detailed description of the present invention, the color of the beacon light to be described later may be multicolored, but is limited to three colors (red, green, yellow) for convenience of description and to synchronize with the function of the beacon light that is mainly used in actual industrial sites. In this case, red means "failure or warning", green means "normal", and yellow means "caution or atmosphere".

1 is an exploded perspective view of an exemplary beacon in accordance with the present invention, Figure 2 is an exemplary cross-sectional view showing the assembled state of the beacon in accordance with the present invention, Figure 3 is an exemplary configuration of a microprocessor for LED control according to the present invention It is a block diagram.

As shown in Figures 1 to 2, the warning light according to the present invention is configured in a similar form to the existing, for example, the base 100 is fixed to the bottom surface, in the form installed in the center of the base 100 The integrated post 110, the body 120 fixed to the upper end of the post 110, the electronic circuit board 130 embedded in the body 120, the body to seal the electronic circuit board 130 The outer cap 150 is assembled to the upper end of the 120 and the inner circuit 140 is interposed between the electronic circuit board 130 and the outer cap 150.

At this time, the base 100, the post 110, the body 120, etc., which is an incidental component constituting the warning lamp according to the present invention is preferably configured in the same structure as the existing, but is determined in the relevant law requiring an industrial warning lamp. It is more desirable to be configured to reduce the manufacturing cost and efficiently utilize resources by minimizing the size within the scope of the existing standard.

In addition, the post 110 and the body 120 is more preferably configured to be separated from each other to ensure the ease of maintenance.

In addition, the body 120 and the outer cap 150 has a shape in which two ends are divided into two vertically cylindrical members blocked at both ends. In this case, the outer cap 150 forms a hemispherical or tower sphere to a dome shape. In order to be easily assembled to the body 120, the stepped portion 122 is formed along the upper inner edge of the body 120, and the groove (not shown) is formed on the opposite portion of the outer cap 150 By having an assembling structure of the type fitted to each other it can be more easily assembled and separated.

Here, as shown in Figure 2, the inner surface of the outer cap 150 is formed with a plurality of projections 152 long in the transverse direction, which is the projection 152 when the light generated in the LED (L) is emitted to the outside ), The reflection and refraction are repeated to reduce dispersion and to induce concentrated divergence to the side.

At this time, only the projection 152 is not shown in FIG. 1 due to the difficulty of expression, and since it is specified in FIG. 2, the shape may be sufficiently understood by referring to this.

In addition, since the high information 124 is protruded in the inner center of the body 120, the electronic circuit board 130 is guided to be fitted, and in some cases fixing members such as screws or bolts not shown Through the electronic circuit board 130 may be to be firmly fixed in the body 120.

In addition, the LED (L) is disposed on the electronic circuit board 130, wherein at least one LED (L) is preferably provided.

Here, the number of the LED (L) may vary depending on the workplace environment, such as the case of a large workplace is far from the facility (industrial machinery), the distance from the operator, or if the facility is distributed installation In the case of a business that requires high concentration within the visible distance, the number of LEDs (L) is arranged in such a way as to have as many as 5 to 10, and in a small workplace, one LED (L) serves as a sufficient warning light. It can be done.

In addition, if necessary, a plurality of holes may be formed at predetermined intervals along the border between the body 120 and the outer cap 150, and the above-described LEDs may be installed therein, and the LEDs (L) described above are all the same shape. At least three colors (red, green, yellow) in one sphere are LEDs (L) which can be selectively expressed by a control signal.

In addition, the body 120 and the outer cap 150 is preferably formed of a transparent or semi-transparent material so that it is possible to further enhance the identification of the warning light.

In addition, the electronic circuit board 130 is the most essential configuration of the present invention, at least one LED (L) is mounted on the main board 132, the main board 132 and the color appearance An auxiliary substrate 134 mounted with additional elements for processing a control signal for the microprocessor (M) and a microprocessor (M) that performs a main function for control while being connected to the main substrate 132 through the auxiliary substrate 132. And a socket S for connecting the control board 136 mounted thereon and a lead wire for supplying power required for the control board 136.

At this time, in some cases, it is not necessary to have a plurality of substrates described above, these may be integrated in a single substrate, and the LED (L) may be mounted thereon to simplify and simplify the structure. It is merely indispensable explanation for convenience of understanding.

Here, when the LED (L) is to use the DC according to the light emission voltage, the transformer can be mounted on the electronic circuit board 130 so that the voltage transformed through the transformer (not shown) can be used. Of course it is.

The microprocessor (M) communicates with a main controller (M10) for transmitting a control signal, an LED module (M20) connected to transmit and receive a signal with the main controller (M10), and the LED module (M20). And a signal control unit M40 connected to the LED module unit M20 for storing color data and transmitting a signal to the LED L so as to express the set color data. LED L is connected to the signal controller M40, and an input unit I for inputting information is connected to the main controller M10 when necessary.

In this case, the input unit I may be a keypad type directly input by an operator through a control panel, a sensor installed in a workplace if necessary, or may be a control PLC installed in an industrial machine.

In general, since the LED (Light Emitting Diode) uses a semi-permanent semiconductor that directly turns electricity into light, it is possible to adjust the color to be expressed by adjusting the color-related signal applied through the signal control unit (M40).

In other words, in the semiconductor, high energy electrons are converted into low energy states, and the original energy is emitted as light, and the color of light is determined by the height at which the electrons jump out, that is, the energy difference. In the blue system, which is light having a short wavelength, is expressed, and when it is small, the light of a red system having a long wavelength is expressed.

By using this principle, in the state in which the color signal capable of emitting light corresponding to red, green, and sulfur in the example of the present invention is stored in the EP-ROM M30 in advance, The main control unit M10 controls the LED module unit M20 so as to produce a desired color, and the LED module unit M20 receiving this signal receives color data corresponding to the corresponding color from the EP-ROM M30. After calling the signal control unit (M40) to control the plurality of LEDs (L) connected to it will be able to immediately express the light of the corresponding color.

Here, the process of expressing a multi-color through one LED (L), for example, assume that there are four pins in one LED (L), one of the pins leave the anode (Anode) in common ground The remaining three pins are designated as cathodes and connected to the LED module unit M20, so that the electron flow of a suitable color according to the applied voltage is given from the anode to the cathode. Efficient and effective one-point multi-color expression LED (L) can be implemented.

In some cases, one pin may be used as a cathode and the other three pins may be defined as anodes to adjust an applied voltage so that an appropriate color of the LED L may be expressed.

Therefore, as many LEDs (L) are assembled to the electronic circuit board (130) as many as the number of colors required to be connected to the pins of the same position to be the same color, so that a plurality of LEDs (L) to express the same light. You can do it.

In addition, although not shown in the microprocessor (M), a timer (Timer) for communicating with the main control unit (M10) is mounted, and configured to control the light emission of the LED (L) in a manner of blinking at regular intervals instead of always on. Of course, the identification can be further increased.

On the other hand, the inner cap 140 is interposed between the electronic circuit board 130 and the outer cap 150, the inner cap 140 is a shape of the circular container overturned with a band of a predetermined width along the outer peripheral surface Dome-shaped ceiling portion 148 formed with a bottom portion 142, a side portion 144 having a spirally inclined surface at a predetermined interval toward the top, and a central portion protrudes downward to form a U-shaped recess 146 when viewed from the outside. The inner surface of the inner cap 140 is a vertical projection 147 is formed up and down from the bottom to the downward protrusion of the recess 146 in the center of the ceiling, the outer surface of the side portion 144 is horizontally The long horizontally protruding triangular lateral protrusions 145 are totally spaced at regular intervals or have a structure that is continuously formed in an outer spiral shape.

In this case, the bottom portion 142 of the inner cap 140 is formed in a wide band so that the inner cap 140 is formed so as to be well fixed to the upper surface portion of the electronic device 130, as well as the electronic circuit board 130. It is fixed by adhesive, bolts, screws, etc. on the inner surface, and protrudes vertical projections 147 on the inner surface to form a plurality of long cells up and down, the light emitted from the LED (L) by the unit of light In order to achieve the coupling and to guide the light to the recess 146 of the ceiling 148, the triangular lateral projections 18 formed on the outer surface of the side portion 144 is the light combined in units of cells inside In order to maximize the luminance in the lateral direction by suppressing the dispersion to the upper side in the cap 140 is emitted to the upper side and by forming a pillar of light in the center to diverge the light to the side.

In addition, the ceiling 148 is domed and the concave portion 146 is formed in the center to guide the light collected in each of the vertical projection portions 147 to the concave portion 146 to collect these lights. This is to increase the brightness by generating a pillar of light by.

In addition, the above-described body 120, the electronic circuit board 130, the inner cap 140 and the outer cap 150 has been described focusing on being circular as a form of a preferred embodiment, but is not necessarily limited to triangle, square Of course, it can also be formed in a polygonal shape.

The warning lamp according to the present invention having the configuration as described above is directly mounted on or fixed to the industrial equipment as in the past, so that the operator can be promptly informed and acted upon in case of malfunction or emergency situation of the industrial equipment. It can be used as a warning light.

In particular, according to the principle described above, it is possible to select and express the required color among at least three colors through one LED (L), thereby reducing the installation cost and simplifying and simplifying the structure of the warning light installation. Volume and size can also be freely adjusted to maximize its utility.

As described in detail above, the present invention has only one color in one sphere, so that the installation structure is complicated, difficult to maintain, and the structure is simplified and simplified compared to the conventional light lamp, which has inconvenience due to large volume. Since it can be reduced, it can reduce installation cost and maintenance cost, and it can be manufactured to the smallest size within the standard, thus providing great effects such as eliminating the constraints of the installation site and saving resources due to efficient use of resources.
