The present invention relates to a street light retrofit method using an electrodeless lamp. More specifically, the present invention relates to a street light retrofit method using an electrodeless lamp, characterized in that the mogal is removed from a common street lamp and the electrodeless lamp is installed using a heat sink and a ballast.

In general, street lamps are lighting facilities installed along the street for the safety and security of street traffic. These streetlights have a highway type that bends the ends of the poles in accordance with the type of electric poles, and the branches extend horizontally at the ends of the poles. It is classified into the head of the head (주 型). Such streetlights are installed according to the installation places such as highways, main roads in downtowns, commercial roads, and residential district roads.

Street lamps generally use a high-pressure discharge lamp or a fluorescent lamp such as a metal halide lamp, a sodium lamp, a mercury lamp, or the like as its light source. In particular, the high-pressure discharge lamp has improved lifespan, light efficiency (lighting efficiency), color rendering, and light color retention rate than fluorescent lamps, and is currently used as a light source of a street lamp.

Referring to the general configuration of such a conventional street light as follows. 1A and 1B are perspective views for explaining the structure of a conventional street light. 1A and 1B, the conventional street lamp 100 includes an electric pole 110, an arm 112, a lamp housing 120, a partition 122, a first internal part 130, and a high pressure discharge. The lamp 132, the mogal 134, the binding member 136, the second internal part 140, the power supply line 142, and the arm fixing part 144 are configured to be included.

Arm 112 is a member which protrudes from one end of electric pole 110 and is inserted into first interior portion 130 of lamp housing 120.

The lamp housing 120 is a case for protecting the lamp of the street lamp and is made of a hard material so as not to be easily damaged by external pressure. One surface or the front of the lamp housing 120 is formed with a cover of a transparent material so that the lighting function can be performed smoothly.

The partition 122 is provided in a plate shape that divides the lamp housing 120. By the partition 122, the lamp housing 120 is divided into a first interior part 130 and a second interior part 140.

The first interior portion 130 includes a mogal 134 provided on one side of the partition 122 and a high-pressure discharge lamp 132 mounted to the mogal 134.

The mogal 134 functions to supply power through a contact with the high-pressure discharge lamp 132 to a conventional socket.

The binding member 136 is a member for binding the mogal 134 to the partition 122 and is realized as a bolt (or screw).

The second interior portion 140 mediates the electric pole 110 and the first interior portion 130, for this purpose is provided with an arm fixing portion 144 for fixing the arm 112 on one side of the inner surface. And, the power supply line 142 is connected to the mogal 134 from the pole 110 through the arm 112 to provide power.

However, the high-pressure discharge lamp provided in the conventional street lamp 100 requires a preheating time (5 minutes to 10 minutes) required to vaporize all of the intrinsic filling materials at the time of lighting. This provides a disadvantage in lighting control for determining whether the illumination is substantially improved or poor when used as a street light source. In addition, the high-pressure discharge lamp has a fire risk because the surface heat generation level reaches 200 ℃ ~ 300 ℃. In addition, the high-pressure discharge lamp has a very high mercury content of 20mg ~ 30mg has the problem of facing environmental pollution problem at disposal. In addition, the high-pressure discharge lamp has a high level of glare, which is constrained to secure the field of view, and the light beam deterioration rate is fast, and its life is relatively short. This problem has produced the inconvenience of having to replace the lamp relatively often when used as a street light source.

Moreover, high-pressure discharge lamps were not suitable for street light sources because their brightness levels were so low that they could not clearly recognize nearby buildings when used for night lighting (ie, relatively low color rendering with a color rendering index of 28 to 65 Ra).

Accordingly, the use of an electrodeless lamp as a light source for a street light is emerging, but for this purpose, the internal configuration of the street light must be changed in its entirety. However, there is a problem that discarding the existing street lamp and replacing with a new street lamp can cause a huge cost waste.

In order to solve the above problems, the present invention, the street lamp using the electrodeless lamp, characterized in that to remove the mogal from the conventional general street lamp and to install the best electrodeless lamp for the light source using a heat sink and ballast to maximize the recycling of resources. It is an object of the present invention to provide an improvement method. Preferably, an object of the present invention is to provide a street light retrofit method using an electrodeless lamp suitable for each of the types of street lights are classified into three types of road type and trade road type.

In order to achieve the above object, the present invention provides a method for replacing a light source of a general street lamp with an electrodeless lamp, the method comprising the steps of: (a) removing the mogal and the existing bulb in the lamp housing covering the light source; (b) mounting a heat sink for supporting the electrodeless lamp and the electrodeless lamp to the lamp housing; And (c) mounting a ballast to the lamp housing which generates a high frequency in the electrodeless lamp so that the electrodeless lamp is illuminated.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used as much as possible even if displayed on different drawings.
