Abstract:
A LED lighting apparatus is popular as a lighting apparatus because it lasts long if proper temperature maintains and power consumption per unit lighting apparatus is low. The present invention solves the problem of linearity of the light by determining the light distribution characteristics through the decision of each angles of a center part light emitting surface and the light emitting surface connected to four sides of the center part light emitting surface. Also the present invention solves the problem generating by the heat in the LED lighting apparatus by having characteristics to exhaust the heat to the outside air by the heat conduction on an electric wire, wherein the heat is generated from each substrates by the LED lighting emitting.
Abstract:
The present invention relates to a cooling apparatus for maintaining the temperature of a solar cell under 50 in the summer in order to increase average yearly efficiency of a photovoltaic power plant. Aluminum or Iron pipe for conducting geothermal heat to a solar cell is laid underground and absorbs the geothermal heat, and rectangular shaped aluminum or iron plate is connected to a cut inclined surface at an upper end of the aluminum or iron pipe on the ground. A back surface of a solar battery module is attached to an upper surface of the rectangular shaped aluminum or iron plate, and the aluminum or iron plate getting cool as a result of conduction of the geothermal heat is connected to the back side of a solar battery, thereby absorbing the heat.
Abstract:
PURPOSE: An independent power supply apparatus by a hybrid method of a solar cell and a wind power generator rotating an outer frame are provided to reduce the mechanical loss due to an accelerating unit by using a blade that is directly fixed to the outer frame of power generator and that has much impetus, and to generate power under condition of breeze by attaching, at the end of blade, a large hinge that has large wind resistance. CONSTITUTION: An independent power supply apparatus by a hybrid method of a solar cell and a wind power generator rotating an outer frame has at least two ⊂-shaped blades (6) fixed to the outer frame of generator (18) in a vertical direction. The edge vertical to ⊂-shaped blade that is positioned at the respective end of blade is fixed to the center inward in an angle of 60 degrees between the plates (3) of square plate shape hinge that is opened in an angle of 60 degrees. The peaked end toward the rotation shaft of hinge that meets the plates of hinge is made up so as to direct from the same direction to the same direction. As viewed from the sky, by the hinge that has a V shapes and that is fixed to the end of blade, one side is formed to have large wind resistance and the other side has a streamlined shape to have less wind resistance.

PURPOSE: An aerogenerator with blades adhering to the outside frame of a generator is provided to increase wind power availability by installing more than one set of blades on the outside frame of the generator and to install a plurality of NS magnetic poles by using a cylinder with a large diameter, thereby having no need to use a speed increaser. CONSTITUTION: An aerogenerator with blades adhering to the outside frame of a generator includes a circular rod(1) and a rectangular structure(4) which is composed of square pipes formed with two edges(2) and bottom sides(3), and built in the air perpendicular to the ground. A linear circular rod(6) with a fixed length, which is welded to the center of the bottom side of a rectangle vertically to the ground, is connected through a bearing to a supporting fixture which is installed on the ground. The circular rod on the bottom side of the rectangle is inserted with two cylinders which are composed of a large cylinder(7) and a small cylinder(80) which is contained in the large cylinder. Circular rods are insertedly fixed respectively on the centers of circular plates of both sides of the small cylinder in an identical way in which the circular rod on the bottom side of the rectangle is inserted into the two cylinders, and inserted into the centers of bearings which adhere to the centers of circular plates of both sides of the large cylinder.
