The trend of production and dissemination of LED lighting devices and luminaires, called LED lighting fixtures, which are being promoted worldwide and showing overheating is expected to be further activated in the future. In particular, LED lighting equipment, which has the advantages of low power consumption, which is innovatively improved compared to conventional luminaires, has emerged as the only alternative to the green technology era compared to various lighting fixtures developed to date, and the demand for LED lighting equipment will continue to increase for the time being. It seems to be. In 2012, when the Kyoto Protocol enters into force, the demand for LED lighting fixtures from around the world is expected to increase explosively.

However, it is also true that not only the advantages of the LED lighting fixtures, but also the need for market demand, have not been able to release products with technically clear completions. In other words, there are still incomplete degrees of effective heat dissipation technology or heat generation reduction technology for treating heat generated from LED devices, and SMPS, which supplies power to LED devices, is trying to increase its service life. To date, the perfect product is not available due to the completed technology. In particular, LED lighting fixtures for street lights are installed at a height of about 5m to 10m from the ground, so the surroundings of the LED lighting fixtures look bright, but the ground just below the LED lighting fixtures is very dark. Therefore, in the case of LED luminaires for street lamps that must have a closed structure, there are two technical problems, how to effectively radiate heat generated from the inside to the outside, and how to reach the light emitted from the LED elements to the ground. The reality is that it is not completely solved.

Therefore, the present invention effectively solves the heat problem in the enclosed streetlight LED lighting fixture by a new heat dissipation structure, easily manufacture and install the LED lighting lamp for the street lamp, and the light emitted from the LED device is very effective. The purpose of the present invention is to provide an LED lighting device for street lamps in which the optical distance is organically combined to economically increase the lighting distance to reach the ground.

Street light LED lighting device of the present invention for solving all the above problems, the LED lighting device for street light employing an LED module, the predetermined LED module means; Supporting the LED module means from the top side by side in a predetermined length direction of the LED lamp, the guide groove is formed in the side of the rail, and formed a small groove on the surface of the aluminum LED module support further improved heat dissipation efficiency absence; And a predetermined tube shape, one side of which is opened in a predetermined length direction, and both open ends thereof are detachably inserted into a guide groove of a rail shape of the LED module supporting member to protect the LED lights. It characterized in that it comprises a cover tube which is integrally molded with a rod-shaped lens or a circular lens spaced at a predetermined interval in a predetermined length direction.

Here, a predetermined clamp is used to facilitate maintenance while fixing both ends of the cover tube detachably inserted into the rail-shaped guide groove of the LED module support member, and also cover edges at both ends of the protective cover. It is preferable that the silicone rubber band is compressed to further enhance the sealing property.

The present invention is an LED lighting device and its luminaire employing a LED module for street light, the nature of the street lamp fixtures that must be produced in a sealed waterproof type on the back of the LED Modue to enhance the function of effectively dissipating heat generated from the LED element to the outside By attaching a rail type aluminum heat sink, it meets the waterproof sealing function and at the same time shows the heat dissipation function.The sealing of both ends of the protective tube is made of silicone rubber so that the plug can be pressed to make it sealable. It could be used. In addition, the lens function is integrated with the tube at the bottom of the LED protection tube so that the light can reach the ground under the street lamp very effectively. Especially, it is designed to add various types of lens functions such as round lens type and long straight lens type, which are spaced at regular intervals, not only to reduce the production cost but also to selectively add necessary functions according to the use. Designed to be developed and produced.

Therefore, the present invention solves all the problems of the conventional LED lighting device for street lamps, the construction is simple, the construction cost is low, and the maintenance is very convenient and at the same time the scope of LED lighting is very wide compared to the existing and effectively to the ground The present invention provides an LED lighting device and its luminaire employing a significantly improved LED module for street light that can be reached. Therefore, the problem of heat dissipation of the LED lighting fixture for street lamps and the light emitted from the LED element did not reach the ground did not maintain the proper brightness through the present invention is solved by solving the problem, LED lighting fixture in the future streetlight The utilization is expected to be promoted. In addition, if the street lamp-type LED lighting device according to the present invention is actively employed in street lamps that are public goods, and these results are fully promoted, the utilization of LED lighting fixtures in the private sector will be further promoted. I think you can. In addition, as well as savings from energy savings, the cost of maintenance and other incidental expenses of the lighting fixtures is greatly reduced, which can be expected to have many economic effects in terms of consumers.

The present invention is a lighting device and a luminaire utilizing an LED element for efficiently exerting a function as a luminaire to replace a conventional street light. In general, the conventional LED device is manufactured through a filter with a translucent or constant pattern to spread the light widely on the front surface of the light emitted because the light emitted is straight. However, since the wavelength of light emitted from the LED is relatively shorter than that of general visible light, the brightness is maintained only in the vicinity of the LED lighting fixture, and the amount of light reaching the ground is not much. The brightness of is not maintained enough.

Therefore, in the present invention, by applying the optical function to the filter function, a portion of the light emitted from the LED element is immediately spread to illuminate the surrounding area, and the remaining amount passes through the lens function portion having a focal length suitable for the distance to the ground. It is designed to achieve efficient dimming overall. The application of this technique has revealed that the lighting range by the light emitted from the LED device is formed in a double, thereby having an effect of visually extending the lighting range and its distance, the results of repeated experiments according to the inventors.

In addition, due to the characteristics of street lamp lighting fixtures that must be manufactured in a sealed waterproof type, it is possible to effectively radiate heat by attaching an aluminum heat sink to the back of the LED module to which LED elements are attached to effectively radiate heat generated from the LED elements to the outside. At the same time, it is easily attached to the structure of the street lamp so that the lighting function of the street lamp can be displayed for stability.

In particular, both sides of the tube of acrylic or other resin material, which is in charge of the filter function and the protection function of the LED module, are proposed to be easily opened and closed according to the present invention in which a crimped silicone band is attached, thereby maintaining the waterproofing effect. The convenience of repair is further enhanced.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 7, the lighting apparatus according to the present invention is manufactured to integrally form a function such as a convex lens at the lower end of the LED protection tube 20 so that the light can be efficiently collected and reached to the ground under the street lamp. Here, the lens function part 40 is designed to add various types of lens functions, such as round lens type and straight lens type, to reduce the production cost and to selectively add various functions according to the use. The product is designed to be developed and produced. More specifically, a method of adding a lens function for increasing an illumination range and distance includes a rod-shaped lens insertion method and a circular lens insertion method spaced at regular intervals. In the case of the rod pattern type, the tube is produced by integrally molding the extrusion mold according to the shape when the tube is manufactured by the extrusion method. If you want to insert a circular lens can be produced by the foaming method or injection method. However, the circular lens insertion method has a disadvantage that the mold cost is relatively high. In the case of manufacturing an LED lighting device by inserting a lens function, the bar pattern lens method is applicable to a distance of 3 to 5 m within a relatively short distance from the ground, and has a height of 7 to 10 m. In the case of a street lamp, it is effective to make a tube with a circular lens.
