In general, outdoor spaces that require bright lighting at night, such as airports, harbors, sports facilities, parks, and parking lots, have been operated by installing lighting towers or lighting towers equipped with a plurality of luminaires on tops of props.

Luminaires applied to such light towers or light towers are commonly referred to as floodlights, and are a total reflection type floodlight utilizing the illumination angle of the built-in light source and an asymmetrical type that refracts the illuminated light to be concentrated in a desired direction. It is divided into floodlights, and a reflection cover called an irradiation angle limiting cover or a reflector is used together as necessary.

In addition, the floodlights described above are manufactured and applied to floodlights having various outputs according to the installation purpose, the installation location, or the installation conditions. The floodlights having the best output in consideration of the lighting range, the brightness and the uniformity are evenly taken into account. It will be installed by reflecting the design at the time of design.

Therefore, conventional floodlights have similar shapes and structures, and their sizes vary according to various outputs, and the lighting bodies, the cover bodies, and the light sources are manufactured according to the sizes of the outputs, and then combined with each other. To produce.

The general structure of such a floodlight is, as registered in Korean Patent No. 10-1187560, is provided with a plurality of LED modules in a plurality of arrangements can provide lighting in a wide range, and by adjusting the illumination angle up and down and left and right three-dimensional It can be adjusted by the fixing member, the LED module and the controller can be stably protected by the fixing member, and can be confirmed through the LED floodlight, etc., which has a remarkable effect that is simple and easy to install.

In addition, the housing and the heat dissipation is formed integrally, such as Patent No. 10-1237169; An LED light source unit mounted inside the housing to emit light by driving the LED to realize lighting; A transmission cover coupled to the front side of the housing from which the light is emitted from the LED to transmit the light emitted from the LED and to seal the inside of the housing in which the LED light source is installed; A dehumidifying unit installed inside the housing and removing moisture generated by a temperature increase when driving the LED light source unit; One side is coupled to the housing and the other side is coupled to the struts of the lighting tower is installed in the port; LED floodlight for the port lighting tower configured to include the design and registration.

An LED lighting device having a structure including a second protrusion and a fixing portion having a first protrusion inserted into a first groove is formed and registered.

Subsequently, as shown in Korean Patent No. 10-1578039, the rear of the housing is provided with a heat dissipation unit having a structure that allows air to flow up and down, front and rear, and an infrared irradiation unit above or below the front part of the housing. An LED floodlight of the lighting tower has a light shield provided at an upper side of the front portion of the light tower, and the reflector is provided with a reflector that can selectively adjust the inclination of the light shield.

However, in the conventional LED floodlights, the LED light source plate and the cover body, and the frame and the packing according to the respective outputs, as well as the lighting main body to be produced separately, and determining the output of the floodlight is connected to the power supplied. It is determined by the number of light sources of the LED light source plate and the individual outputs of the light sources. As the output increases, the size of the flood light is inevitably increased.

Therefore, in order to provide all the floodlights having different outputs, all components for each output must be manufactured. In order to manufacture all of these components, each component produced as well as the economic burden due to expensive mold cost There is also considerable difficulty in storing and managing them all.

In particular, such a floodlight has a problem that the front lens or the cover body becomes cloudy due to condensation due to a sudden change in temperature, and thus does not produce a desired illuminance. Various structures have been attempted to prevent this.

For example, as shown in Korean Patent Laid-Open Publication No. 10-2009-0020436, a lighting lamp is installed and is installed in water or underground, and moisture in the air inside the housing is condensed by a temperature difference between an external temperature and an internal temperature of the housing. In order to reduce the temperature difference between the inside and the outside of the housing, the outside air is introduced into the interior of the housing, the lighting device having an air flow means for allowing the internal air of the housing to be discharged to the outside There is a bar.

In addition, by adding a dehumidification function for dehumidifying the moisture generated by the temperature difference inside and outside the housing, as registered Patent No. 10-1237169 to compensate for the weakness of the LED luminaire installed in the port, to implement a higher quality floodlight fixture In order to establish a 24-hour port operating system, an LED floodlight for a port lighting tower was devised and registered.

Subsequently, as illustrated in Korean Patent No. 10-1407621, a light emitting unit having an LED device that emits light when power is applied; A heat dissipation unit provided to receive heat generated from the light emitting unit when the light emitting unit emits heat, and to dissipate heat by dissipating the heat in a larger area than the heat generating area of the LED device; A heater installed between the light emitting unit and the heat radiating unit; A body portion having a structure provided with an upper opening and a lower opening, the lower opening being fitted to an upper portion of the heat dissipation unit; A light transmitting plate which is spaced apart from the LED element by a predetermined distance and connected to the body part to cover the upper opening, through which light emitted from the LED element is transmitted; It is installed between the heater and the floodlight plate, and is connected to the heater to receive heat from the heater, and transfers the heat generated from the heater or the light emitting part to the floodlight plate, to prevent the formation of condensation on the floodlight plate in the cryogenic state Devices for heat dissipation and low temperature driving of LEDs including heat transfer units have been devised and registered.

In addition, as disclosed in Korean Utility Model No. 20-2016-0001465, an LED lighting module is provided on the inside to irradiate light to the outdoor object, and a plurality of heat dissipating protrusions are formed on the outer surface of the LED lighting module to radiate heat. Upper and lower main cases formed with a through hole for fluid access; The radiator wraps around the heat dissipation protrusions disposed at both sides of the through hole, and the lower end thereof is a hole cover spaced apart from the bottom of the heat dissipation protrusion.

However, the condensation preventing or dehumidifying structure of the lighting device or the light emitter as described above mostly consists of an air circulation structure for circulating the air and the outside air inside the light emitter, or dehumidification is performed by applying a separate heating means therein. However, all of them have a problem in that they do not perform effective condensation prevention or dehumidification.

In other words, the condensation prevention structure by the air circulation structure inevitably causes a sudden change of temperature in the internal environment of the high temperature and high humidity transmitter, that is, condensation still occurs on the cover body at the moment when the transmitter is turned on. It is not enough to prevent the condensation caused by the outside air.

In addition, the light emitter for the dehumidification is performed through the heat generating means inside, when the lighting heat of various light sources is generated, condensation still occurs due to a sudden temperature difference between the inside and outside of the light source, and the heating means and the light source are lit. The heat is mixed, so the condensation is worsening.
