Abstract
An LED lamp includes a lamp post, an illumination unit fixed on the lamp post, and a generator disposed in the lamp post and coupled to the illumination unit electrically. The lamp post defines an airflow passage along a longitudinal direction thereof. The airflow passage communicates with an outer environment. The generator is adapted for converting wind energy to electric energy, and includes a rotary turbine arranged in the airflow passage. The rotary turbine includes a hub and a plurality of blades around the hub. Each of the blades includes a top face and an opposite bottom face. The top face and the bottom face are symmetric to a plane which extends through opposite connecting edges of the top and bottom faces and is perpendicular to a rotary axis of the turbine.
Claims18
An LED lamp comprising:
- a lamp post defining an airflow passage along a longitudinal direction thereof, the airflow passage communicating with an outer environment;
- a generator disposed in the lamp post to convert wind energy to electric energy, the generator comprising a rotary turbine arranged in the airflow passage, the rotary turbine comprising a hub and a plurality of blades around the hub, each of the blades comprising a top face and an opposite bottom face, the top face and the bottom face being symmetric to a plane which extends through connecting points of the top and bottom faces;
- and
- an illumination unit fixed on the lamp post and coupled to the generator electrically.
An LED lamp, comprising:
- a main post adapted for fixing the LED lamp on the ground, a first tunnel being defined in the main post, and a plurality of through holes being defined in a top portion of the main post to communicate the first tunnel with the outer environment;
- a branch post comprising a first end joint to the main post and an opposite open second end, a second tunnel being defined in the branch post and communicating with the first tunnel, the open second end communicating the second tunnel with the outer environment;
- an illumination unit fixed on the top portion of the main post;
- a generator coupled to the illumination unit electrically, the generator comprising a rotary turbine arranged in the second tunnel, the rotary turbine comprising a hub and a plurality of blades around the hub, each of the blades comprising a first face and an opposite second face, the first face and the second face being symmetric to a plane which extends through opposite connecting edges of the first and second faces.
