20090016055 | HIGH-POWER LIGHT EMITTING DIODE (LED) STREET LAMP AND BODY FRAME THEREOF - A high-power light emitting diode (LED) street lamp includes a body frame, a plurality of light emitting diode (LED) modules, and a base unit convexly positioned on the body frame along the light emission direction of the high-power light emitting diode (LED) street lamp. The light emitting diode (LED) modules have a plurality of light emitting diodes (LEDs), and at least one circuit board. The light emitting diodes (LEDs) are electrically connected to the at lease one circuit board to be served as the light emitting diode (LED) modules. The base unit has a plurality of supporting surfaces which support the light emitting diode (LED) modules. The supporting surfaces are symmetrically positioned on a normal direction of an end surface of the base unit, and the light emitting diode (LED) modules are positioned on the adjacent supporting surfaces, respectively. The supporting surfaces further comprise a plurality of first supporting surfaces adjacent to the normal direction of the end surface of the base unit, a plurality of second supporting surfaces adjacent to the first supporting surfaces, and a plurality of third supporting surfaces adjacent to the second supporting surfaces. An angle formed by the first supporting surfaces and the normal direction of the end surface of the base unit is in a range between 76 degrees to 86 degrees. An angle formed by the second supporting surfaces and the normal direction of the end surface of the base unit is in a range between 49 degrees to 59 degrees. An angle formed by the third supporting surfaces and the normal direction of the end surface of the base unit is in a range between 37 degrees to 47 degrees. | 01-15-2009 |
