Intensive heat-dissipating rotating LED streetlamp

Abstract

The invention discloses an intensive heat-dissipating rotating LED streetlamp. The intensive heat-dissipating rotating LED streetlamp comprises a pole, a transverse connecting rod and a streetlamp body; a connector is arranged between the streetlamp body and the transverse connecting rod; the connector is connected with a cross beam connecting rod through a rotating shaft; the streetlamp body comprises a housing, a lampshade and a cavity defined by the lampshade and the housing; a circuit board is arranged in the cavity; a retaining plate is connected to one side of the circuit board; a plurality of LED lamp beads are arranged on the retaining plate and fixed on the retaining plate by means of a lamp bead heat-dissipating adhesive; a radiator is arranged on the other side of the circuit board and radiating fins are arranged on the other side of the radiator, and a plurality of transverse radiating-dissipating holes are formed in the radiating fins. The intensive heat-dissipating rotating LED streetlamp is convenient to repair; different heat dissipation structures enable heat dissipation to be thorough, and therefore, lots of heat generated by mutual contact of two parts is reduced, the LED lamp beads are protected, and the risk of shortened service life due to a too high temperature is reduced.

Description

technical field [0001] The invention relates to a street lamp, in particular to a rotating LED street lamp with strong heat dissipation. Background technique [0002] Road lighting is an important part of urban lighting. Traditional street lights often use high-pressure sodium lamps to emit light at 360 degrees. The disadvantage of large light loss has caused a huge waste of energy. Therefore, the development of new high-efficiency, energy-saving, long-life, high color rendering index, and environmentally friendly LED street lamps is of great significance to energy-saving urban lighting.

Problems solved by technology

[0003] When designing LED street lights, it is necessary to consider its heat dissipation. At present, thick copper plates are generally used as heat conduction plates, or heat sinks are installed to dissipate heat, but the weight is too large; or fans, heat pipes and loop heat pipes are installed to dissipate heat, but Its high cost and poor convection effect

Generally speaking, the heat sink effect of the existing LED street light cooling device is poor, and the service life of the LED street light is obviously shortened due to the high working temperature, and the existing LED street light heat sink is heavy, inconvenient, and high in production cost.

[0004] In the process of LED street lamp maintenance, due to the problem of the installation angle of the street lamp, it is very inconvenient to repair the street lamp on the corresponding surface, and it cannot be rotated according to specific needs.
