<p>In an LED lamp according to the present invention, the reflectivity of light is improved by using a safety mirror. The transmission surface of the light is freely controlled by controlling a reflection angle. A volume occupied by the heat sink is minimized by using a free space of the lamp. The bottom side of a quadrangular pyramid is located in parallel to the ground. An LED lamp unit is attached on the inner side of the quadrangular pyramid. A safety mirror is attached on a surface without the LED lamp unit of the quadrangular pyramid. A transparent or light diffusion polycarbonate plate is installed on the bottom side of the quadrangular pyramid which is the transmission surface. A square aluminum plate with a preset size is fixed on the upper side of the quadrangular pyramid. Several thin aluminum plates are fixed on the square aluminum plate to be used as a heat radiation unit.</p> |
