This has a possible effect.

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

1 is a perspective view showing a street lamp according to a first embodiment of the present invention, Figure 2 is a perspective view showing a street lamp according to a second embodiment of the present invention, Figure 3a shows a turbine wind power generator of the present invention 3 is a cross-sectional view showing the turbine wind turbine of the present invention, Figure 3c is a cross-sectional view showing the lower support of the turbine wind turbine of the present invention, Figure 4 is a third embodiment of the present invention It is a perspective view which shows the street lamp by.

First, the street lamp according to the first embodiment of the present invention includes a support 10 which forms a basic skeleton and has a lower end embedded in a ground; A wind power generator 20 mounted on an upper end of the support 10 and producing and storing electric power while rotating by wind; A pair of sapphire photovoltaic cells 30 installed at both sides of the support 10 under the wind power generator 20; At least one LED street light 40 for irradiating light to the outside by using the power supplied from the wind power generator 20 under the sapphire solar cell 30; Installed inside the lower end of the support 10 is made of a control unit 50 for controlling the operation of the LED street light (40).

It is a wind power generator that can use high quality power without it.

The wind power generator having the vertical blade 21 has a noise almost in the form of being pushed by the wind as the pressure of the blowing wind, rather than the way the blade blows and winds like a propeller like a wind power generator having a horizontal axis. Therefore, it has the advantage that it can be installed on the roof of residential buildings or urban buildings, but the horizontal axis wind turbine is too noisy, and there is a limitation in selecting the installation place.

The wind turbine generator with the vertical blade is an environmentally friendly product that truly revives the global village by producing high-quality electric power using the resource of wind, which is a clean energy source, and excluding fossil energy exhaustion and global environmental pollution.

Such nacelle is a well-known technique and a detailed description thereof will be omitted.

The use of dynamometers by fossil fuels has caused the hippocampus to burn numerous organics, destroying the natural environment. The sapphire photovoltaic cell 30 of the present invention is manufactured using a transparent sapphire panel 31 based on a plan for converting solar energy into electric power.

Conventional general photovoltaic cells are based on Si crystals, which are silicon as the base material, and the power generation efficiency of such photovoltaic cells does not exceed 13% to 18% and the output power is about 180 W / m 2.

Photovoltaic cell using the sapphire panel of the present invention, that is, sapphire photovoltaic cell has developed the original technology and materials to lower the production cost, power generation efficiency is more than 36%, output power 240 ~ 340 W / ㎡ production price and profit Very competitive.

Since the panel 31 of the sapphire photovoltaic cell 30 is transparent, there is an advantage that it can be installed in two or three floors.

In general, a solar generator is a technology that converts sunlight directly from the sun directly into electrical energy as a power generation method using a solar cell that generates electricity by the photoelectric effect when receiving sunlight.

The sapphire photovoltaic cell 30 is a transparent sapphire panel 31 so that the sunlight inserted into the rectangular frame 32 is transmitted without reflection, a PN bonding layer of a semiconductor on the lower surface of the sapphire panel 31, It consists of a back electrode.

The PN junction layer is manufactured by forming a N-type silicon semiconductor layer by diffusing its surface based on a P-type silicon semiconductor in which boron (boron) is added to silicon. An electric field is generated by this PN bonding layer.

When light is absorbed into the sapphire panel 31, electrons (-) and holes (+) are generated in the N layer and N in the semiconductor due to the energy of the sunlight, thereby moving freely inside the semiconductor. When it moves freely and enters the electric field generated by the PN junction layer, electrons (-) are formed on the N-type semiconductor, holes (+) are formed on the P-type semiconductor, and electrodes are formed on the surfaces of the P-type semiconductor and the N-type semiconductor. When electrons flow to an external circuit, current is generated to supply electricity to the street lamp connected to the sapphire panel and the rear electrode by a wire.

The sapphire photovoltaic cell 30 includes a connecting rod 33 fixed to the rear of the frame 32, a horizontal connecting rod 34 horizontally connected to the connecting rod 33, and the horizontal connecting rod 34.

It consists of nacelle that converts into electrical energy.

The turbine wind power generator 60 is designed to narrow the outlet area while passing the suction air flow through the auxiliary blade 63, thereby accelerating and increasing the air flow of the vortex wind energy. The airflow sliding through the auxiliary blade 63 flows in a tangential direction to the surface to lower the density of the air, thereby further accelerating the airflow moving inside the vertical rotational shaft 61 and creating the airflow in the vortex state in each direction. As air is pushed and the mass of the airflow increases, the vortex wind energy is used as a method of transmitting wind pressure to the internal S-shaped blade 62, so that the wind power device has a high power generation efficiency even in a breeze.

The advantage of the turbine wind power generator 60 is that there is little noise and the rated output is possible even in the breeze regardless of the wind direction.

As shown in Figure 3a to 3c, the turbine wind power generator 60 may be connected in multiple layers to increase the output.
