Problems solved by technology

[0002] LED high-power street lights currently account for an increasing proportion of urban lighting. Although it is well-known for its energy-saving characteristics, the industry is also facing continuous improvement in its heat dissipation problem. After the center of the LED light source is lit, the instantaneous temperature is very high. The heat is exported, even if the heat dissipation area is large enough, the temperature of the center cannot be lowered
[0003] In addition, the PCB boards of LED high-power street lamps currently on the market are generally aluminum boards, but the conduction effect of aluminum is not very ideal, so the heat cannot be taken away in different directions, and the temperature of the center of the LED light source cannot be lowered in a short time
If a fin-type heat dissipation structure is used for heat dissipation, the effect is good because it needs to be exposed, but the street light environment makes the wind flow only in two directions, and the appearance is visually visible, lacking in aesthetics, and limited in shape.

Abstract

The invention relates to a light emitting diode (LED) lamp with a radiating structure, comprising a radiator, a printed circuit board (PCB)and an LED light source arranged on the PCB. The radiator comprises a radiating base and a plurality of radiating posts distributed on the surface of the radiating base; the inner parts of the radiating posts are provided with hollow cavities; a heat conducting unit is arranged between the PCB and the radiator; the heat conducting unit is provided with heat conducting posts which can be inserted into the hollow cavities; and the heat conducting posts are contacted with the cavity wall of the hollow cavities. Because the heat conducting posts can be inserted into the inner part of the hollow cavities and are contacted with the cavity wall of the hollow cavities, the heat released by the LED light source on the PCB plate can be fast conducted to the radiator, and the heat can be fast radiated through the surface of the radiating posts, thereby reducing the temperature of the entire LED lamp, and prolonging the service life of the LED lamp. In addition, by adopting the rhombohedral radiating posts, natural wind can flow in any directions, and the heat can be fast taken away.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an LED lamp with a heat dissipation structure. Background technique [0002] LED high-power street lights currently account for an increasing proportion of urban lighting. Although it is well-known for its energy-saving characteristics, the industry is also facing continuous improvement in its heat dissipation problem. After the center of the LED light source is lit, the instantaneous temperature is very high. If the heat is exported, even if the heat dissipation area is large enough, the temperature of the center cannot be lowered. [0003] In addition, the PCB boards of LED high-power street lights currently on the market are generally aluminum boards, but the conduction effect of aluminum is not very satisfactory, so it cannot take heat away in different directions, and cannot reduce the temperature of the center of the LED light source in a short time. If a fin-type heat dissipation structure ...
