energy saving led street light

Abstract

The invention relates to an energy-saving LED street lamp. The energy-saving LED street lamp comprises a shell body, a chip and a driving plate. Permanent magnet plates are installed on the lower surface of a top plate of the shell body and the upper surface of a bottom plate of the shell body correspondingly. Magnetic pillars are equidistantly and uniformly distributed in the circumferential direction of the driving plate. A ratchet wheel bearing is installed in the center of the driving plate. An outer ring of the ratchet wheel bearing is fixedly connected with the driving plate. An inner ring of the ratchet wheel bearing can unidirectionally and independently rotate relative to the outer ring. A driving rod is further installed on the axis of the inner ring. A resetting device is installed at the lower end of the driving rod. An excitation wire is installed between the driving plate and the top plate. The excitation wire and the chip are electrically connected and form a closed loop. The energy-saving LED street lamp is capable of operating independently, high in safety and stability, simple in structure, low in cost, convenient to install and has great popularization advantages.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an LED lamp for street decoration. Background technique [0002] LED is called the fourth-generation lighting source or green light source. It has the characteristics of energy saving, environmental protection, long life, and small size. It is widely used in various indications, displays, decorations, backlights, general lighting and urban night scenes. Traditional Street lamps are connected in parallel to ensure relative independence. This requires the laying of a complex circuit system underground, and at the same time, waterproof, compressive, wear-resistant and other protection work is required. Therefore, during the installation, use and maintenance of street lamps, it is necessary to invest Excessive costs; at the same time, under special circumstances, the damage of some street lamps may affect the entire power supply network, causing circuit paralysis, causing unnecessary troubles to citize...
