More particularly, the present invention relates to a load-variable type hybrid power-generating street lamp that improves energy efficiency, and more particularly, To a load-variable hybrid power-generating street lamp that improves energy efficiency by enabling a stable power supply according to lighting of a lighting unit.

Generally, the street lamp installed on the side of the street uses commercial power as a power source, and is powered by a timer, a central control, and a sensor to turn on a lamp using a high-pressure mercury lamp, a fluorescent lamp, sodium lamp as a light source, It is more than a certain degree of illumination.

However, since the conventional street light is in a state in which almost no light is on regardless of the illuminance of the surrounding environment at night using commercial power, there is a problem that power loss is large, and in particular, the moonlight is bright or bright It is a wasted power loss nationwide because it will light up the fire continuously until morning.

In addition, the conventional street light has to frequently replace the light source due to frequent failure of the light source, thereby causing a problem of loss of manpower as well as replacement cost.

Such conventional street lamps use a commercially available AC power source supplied from the outside without an artificial power generating facility as a power source, so that it takes a lot of management and maintenance costs, and there is a problem that an electric shock accident occurs due to underground power line exposure at the time of flood .

Accordingly, in recent years, Korean Patent Registration No. 10-1106304 and Korean Patent Registration No. 10-1084721 have proposed a self power generation structure in which electric current is automatically generated by solar light or wind power on a street lamp, The development and dissemination of a street light of a type in which a lighting unit is lit through an electric current is gradually expanded.

In this way, it is possible to save the energy by constructing the electric current through the self-generated electricity structure and lighting the lighting unit through the self-generated electricity structure without depending on the commercial electric current, and especially, it can be installed in an area where the power line is not installed.

However, since the amount of electric current generated through the self-generating structure is limited, it is difficult to turn on for a long time.

In addition, the photovoltaic module forming the self-generating structure may be in the form of a panel, so that the photovoltaic module may be detached from the post due to the extreme wind due to excessive wind, or the post may be torn or bent .

Further, the impeller constituting the wind power generation module does not rotate properly at a low wind speed, and has a limitation in that it is difficult to rotate stably because the center is disturbed at high speed rotation.
