According to the present invention, it is possible to selectively provide switching of HID lamps and LED lamps, thereby maximizing the brightness of HID lamps and LED lamps by maximum output when necessary and minimizing the brightness of HID lamps and LED lamps when unnecessary. It is possible to minimize the consumption, thereby minimizing the power consumption by constantly lighting as the low brightness of the street light, only LED lamp, HID lamp only, or both LED lamp and HID lamp By establishing a control system to adjust the intensity of light in stages as shown, there is an effect that can realize power saving and maximize the productivity. In addition, it is possible to save energy as well as complementary to HID lamps with slow initial lighting by providing LED lamps, and to create atmospheres of various colors according to the color of the lamps, so that space users (pedestrians, users, etc.) Not only can a stable space be used depending on the space where houses, walls, sculptures, and natural objects are installed, but also the direction of illumination, the amount of illumination and the lighting time according to the weather conditions and time zones according to the surrounding environment such as fog and rain. By selectively controlling the LED lamp by varying the light color, it is possible to prevent the light sea that can damage the space user in advance, and by installing the reflector on the top of the HID lamp, The light is reflected by the white reflective paint layer painted inside the reflector to convert it into a surface light source and emit light evenly around. The control system is equipped with a short-range wireless communication module that can easily check whether there are any problems with HID lamp and LED lamp, and establishes a short-range wireless communication network, so that the operation state of the HID lamp and LED lamp can be bidirectionally through the wireless communication module. It can control and automatically detect whether there is any malfunction of HID lamp and LED lamp and notify the user, so it can be used in various ways such as street light, tunnel light, factory light, warehouse light, landscape lighting, etc. In addition, it is possible to obtain a great effect in terms of energy saving by adjusting the illumination according to the situation, and integrated information such as real-time traffic, weather and news information collected by linking the existing intelligent transportation system (ITS) with the street light control system. By transmitting in real time to the LED signs mounted outside the streetlight through the network, Multi-communication with a large number of means of transportation enables the construction of advanced transportation environments, as well as lighting functions and displays using wireless communication that can promptly deal with accidents to space users (pedestrians, users, etc.) The present invention relates to a hybrid street light having a function.

In general, streetlights are arranged at regular intervals on the side of the roadside, both sides of the bridge, and on both sides of the highway to perform the function of illuminating the road. Thanks to the functions of these streetlights, not only can the car drive safely, but it also creates various effects by illuminating the darkness of the city.

Street lighting using such streetlights is for vehicles, pedestrians, natural objects, installations, etc., and to promote safe use under dark conditions by creating a night environment that can induce a quick, accurate and convenient view of the road users. Is designed. Nevertheless, due to the fact that most street lamps are installed in consideration of brightness only, the lack of street lamp layout plan damages trees or reduces lighting efficiency, and hides potential obstacles by giving brightness below KS illuminance standards, thereby threatening users' physical threats. There is a good chance that. In particular, when the illumination of the street lamp is not appropriate, light pollution (hereinafter referred to as 'light pollution') may occur to users.

In addition, street lamps are designed using high-pressure sodium lamps because they require minimal illumination to faithfully perform their functions.However, this high-pressure sodium lamp has the advantage of ensuring the illumination, while high power consumption consumes energy. There are many disadvantages.

Therefore, there is a need for an LED street light to solve this disadvantage. Generally, a light emitting diode (LED) refers to a light emitting diode device. An LED is a device using a phenomenon in which light is generated when a current flows through a PN junction of a compound semiconductor such as GaP or GaAs. By controlling the light emitting diode to generate a light of a constant wavelength can be manufactured. A light emitting diode (LED) is an optoelectronic device in which energy corresponding to a bandgap of a semiconductor is emitted as light when a voltage is applied to a junction structure of a P-type and an N-type semiconductor, and a reaction time is general. Compared to light bulbs, the power consumption is 20% lower than that of incandescent lamps. In particular, the power consumption is relatively low, but the brightness is very bright.

Recently, a number of LED lighting fixtures that can be illuminated with a minimum amount of power has been proposed, but despite these advantages, LEDs lack light diffusion, and when installed outdoors, a short circuit due to lack of heat radiation and flooding There is a problem that it is difficult to be practical without sufficient preparation for proper heat dissipation, waterproofing and diffusion due to high risk of safety accidents.

Accordingly, a high intensity discharge (HID) lamp that emits light by exciting high-pressure xenon gas and a metal compound in the light emitting tube as a high intensity discharge lamp is turned on by a specially designed ballast and a starter generating instantaneous high pressure. When electrons and metal atoms in the light emitting tube collide, the metal compound in the light emitting tube emits a unique light during discharge, and because xenon gas extinguishes the surrounding ultraviolet rays and electromagnetic waves, it produces not light yellow color and good white light. With no filament and fixed tungsten electrodes at both ends of the light emitting tube, there is no troublesome replacement of the lamp due to disconnection of the filament, and stable operation is possible even with power of about 40% lower than halogen lamp. Recently, the industrial lighting market in terms of energy saving and environmental issues Attention has been focused on improvements and uses in HID lamps.

The HID lamp is driven through a ballast that initially applies a high pressure above the discharge start voltage to start discharge upon lighting. The ballast for the HID lamp can be largely divided into magnetic and electronic ballasts. Magnetic ballast has the advantage of simple structure, low cost, and low failure rate because there is no separate control part, while it is difficult to adjust the illuminance, and electronic ballast consists of dimming circuit through voltage adjustment to adjust sequential illumination. This is possible, but the output voltage is low, the lighting of the lamp is unstable and the life is shortened, and there are disadvantages in that the cost is high and frequent failure due to the use of many electronic components.

On the other hand, in the case of industrial sites, there are areas where lighting is good even in a single workplace and no separate lighting is required during the day, while areas where lighting is to be turned on at 100% illuminance during the daytime, or above a certain level of illuminance, even if not at 100% illuminance In many cases, more areas are needed, but in reality, it is a waste of using lights that are constantly provided during the day, and dark space users perceive the street lights dark from the outside, and thus the utilization of the street lights is reduced.

Therefore, it is possible to provide the switching of HID lamp and LED lamp selectively, maximizing the brightness of HID lamp and LED lamp by maximum output when necessary and minimizing the brightness of HID lamp and LED lamp when unnecessary, Minimization can be realized, and the effect of maximizing productivity as well as power saving can be realized, and it is possible to save energy by equipping LED lamps, and to complement each other for HID lamps with slow initial lighting. Various colors can be created according to the space, allowing space users (pedestrians, users, etc.) to use a stable space according to the space where houses, walls, sculptures, and natural objects are installed around the streetlights. The direction of illumination, the amount of light, the lighting time and the light color Changes to the situation the urgent development of a hybrid street lamp having a lighting function and the display function using the wireless communication that is capable of preventing light pollution that could result in damage to, the user space by selectively controlling the LED lamps in advance.

Accordingly, the present invention has been conceived to solve the above problems, and by providing switching of the HID lamp and the LED lamp selectively, maximize the brightness of the HID lamp and LED lamp by the maximum output when necessary, In order to minimize the power consumption by minimizing the brightness of HID lamp and LED lamp, the lighting function and display using wireless communication can minimize the power consumption by constantly lighting as the low brightness of street light.
