Description

TECHNICAL FIELD [0001] The present invention relates to a digital signal control type LED landscape and sign lighting apparatus,

The present invention relates to a digital signal control type light emitting diode (LED) illuminator and a signboard lighting apparatus. More particularly, the present invention relates to a light emitting diode ) Is mounted on a power supply and a signal cable of a single strand, which are integrally formed with each other, so that a printed circuit board and a plurality of strands of a lighting apparatus having a R, G, B LED mounted thereon And signal cables can be electrically connected to each other, and at the same time, it is possible to smoothly control the points / lights of the R, G, and B LEDs provided in each of the scenery and signboard lighting devices through a digital control method So that the installation and maintenance of the landscape and signboard lighting apparatus using the light emitting diode can be carried out simply and at low cost Of course, it was invented to improve the quality of the product.

Recently, as the quality of life has improved, a lot of attention has been focused on comfortable living environment as well as urban beauty.

In this situation, various facilities are installed on the river running through the city, including the bridge that is installed for crossing the river. In order to make the night view of the city more pleasant to the users who use the convenience facilities, It is installed in the main part to illuminate the main part of the bridge, and the night view of mysterious and beautiful atmosphere is produced.

In addition, the illumination of the lighting device installed in the main part of the legs is very diverse in color and shape, so that the night view is created for the driver as well as the pedestrians walking around the bridge.

However, a large amount of lighting lamps are installed in proportion to the length and the width of the legs and the height of the molding, the power consumption is large according to the number of installed lighting lamps, and the initial installation cost and the maintenance cost are increased.

In addition, in order to smooth the flow of traffic in the city center, the pedestrian overpass, which is installed at a certain height above the road, is provided with railings on both sides in order to ensure the safety of pedestrians.

In this way, railings and sculptures representing various shapes of images are installed. In recent years, characters and images symbolizing the city have been shaped and installed in railings and sculptures to effectively inform people about the characteristics and symbols of cities .

However, the above-mentioned effect can be obtained during the daytime, but in the case of the nighttime, since the surroundings are dark, it is difficult to identify the railings and sculptures installed on the railing of the overpass, There is a problem.

Meanwhile, neon lamps, which are generally widely used, are not only free to control their brightness but also have a flicker function as compared with general fluorescent lamps, and are increasingly used. Neon is an inert gas belonging to Group 0 of the periodic table, It is slightly contained in the air, but its amount is 0.00182% by volume (Clark No. 76).

These neon are found in the spectrum of liquid air classification and are colorless, odorless gases, which dissolve 15 ml in 100 ml of water at 20 ° C.

Liquid air is evaporated at low temperature, and it is repeatedly collected together with helium to solidify the neon with liquid hydrogen. This is obtained by separating from helium. The discharge shows a remarkable line spectrum at the red part and a very low pressure It is also used in neon tubes because it discharges in the gypsum tube and glows in red.

In order to construct a signboard or advertisement board or a lighting device by using such a neon light, first, each of the neon lights is combined with one transformer, and each transformer is connected to the flasher.

Then, the power is connected to the flicker. At this time, a converter for converting the normal AC power to the DC power is further mounted.

However, in the case of manufacturing an illumination lamp such as a bridge or a bridge by using a neon lamp or the like, since a large amount of transformers are required as described above, the manufacturing cost is too large and the risk of fire due to the transformer is high And a normal neon lamp has a life span of about one year, but it is easy to break down, so that it is frequently disadvantageous to replace the neon lamp.

In addition, in the case of a fluorescent lamp or a neon as described above, the color of the light can not be varied in various ways, and thus there is a problem that advertisement contents can not be created beautifully including a variety of lights or advertising signs themselves.

Meanwhile, a light emitting diode (LED) has a junction structure of a P-type and an N-type semiconductor and is an optoelectronic device that emits light of energy corresponding to a bandgap of a semiconductor by the combination of electrons and holes when a voltage is applied. Since the reaction time is faster than general bulbs and the power consumption is as low as 20%, it has recently been used in many fields including high efficiency lighting means.

The floodlight using such a light emitting diode utilizes a module in which a large number of high-brightness light emitting diodes or power LEDs are assembled on a substrate as a light source, and is used as a light source such as a signboard, a structure lighting, As a result.

In addition, the illumination lamp using the light-emitting diode may include a method of disposing a plurality of light emitting diodes on a printed circuit board formed in a disk or various shapes so that the light emitting diode can be used as a general illumination lamp and a method of using a solid or flexible And a line bar type method in which a plurality of light emitting diodes are arranged on a printed circuit board at regular intervals.

In the above case, the former is widely used in general illumination lamps and signal lamps, and the latter is widely used in bridges, overpasses, advertisements, and the like.

However, in the case of conventional landscape and signboard appliances widely used for illumination of bridges, overpasses, advertisements, etc. among the above-mentioned illumination lamps using light-emitting diodes (that is, landscape and signboard lighting apparatuses), several LEDs The power supply line and the signal line are directly fixed on the substrate by soldering and the cover is clogged by a cover detachably connected to one side or both sides of the main body so that the light transmitting plate or the condensing lens A light emitting diode type lighting lamp having a line bar shape is inserted into or removed from a rectangular bar shaped body provided with a diffusion lens and the like, and can be pushed in or pulled out through openings on one side or both sides, There is a very inconvenient problem.

Particularly, when each landscape and signboard apparatus is installed, a plurality of control signal lines for connecting / disconnecting the R, G, and B LEDs, including the two power lines, and the color control lines must be individually connected through soldering or connectors In addition to the inconvenience, both power lines and control signal lines independently connected to each of the scenery and signage equipment must be connected to the power supply unit and the controller, respectively, so that the installation and maintenance costs are high. There is a problem that the surroundings of the scenery and the signboard are complicated and unfamiliar.
