Abstract

The utility model discloses a radiating structure of a light-emitting diode (LED) street lamp. The radiating structure comprises a lamp shade, wherein the front of the lamp shade is provided with an LED luminous source; the back of the lamp shade is provided with radiating fins; the radiating fins comprise transverse fins and longitudinal fins; the transverse fins are distributed on the back of the lamp shade in parallel, and two ends of the transverse fins extend out of the lamp shade; the longitudinal fins are perpendicular to the transverse fins, and the transverse fins are equally distributed; the radiating fins are wholly arranged in a fishbone shape and are attractive in appearance and uniform in radiating; and moreover, the two ends of the transverse fins extend out of the lamp shade, so that the heat can be taken away by utilizing the flowing air, and the radiating efficiency is improved.

Description

A kind of radiator structure of LED street lamp

Technical field

The utility model relates to a kind of radiator structure, particularly a kind of radiator structure of LED street lamp.

Background technology

Transitional street lamps generally with high-pressure mercury lamp as light emitting source, high-pressure mercury lamp has higher luminous efficiency and long service life, high-pressure mercury lamp has shortcomings such as light decay is big, light is yellow partially, colour rendering is low simultaneously, should not open many passes more.Characteristics such as that led light source has is environment friendly and pollution-free, little power consumption, light efficiency is high, the life-span is long, along with the development of led light source technology, led light source replaces the lighting source of high-pressure mercury lamp as street lamp day by day.

Because the light source of high-power LED street lamp adopts low-voltage DC supply; Its caloric value is big; Requirement to heat radiation is high, and general LED street lamp all is provided with radiating fin and helps to improve radiating efficiency at the lampshade back side, but existing radiating fin is the scope that directly is arranged in the back side of lampshade and does not exceed lampshade; Air-flow can not well circulate, and radiating effect is not good.

The utility model content

In order to overcome the deficiency of prior art, the utility model provides a kind of radiator structure of LED street lamp, can let air-flow better circulate and take away heat, and radiating effect is significantly increased.

The utility model solves the technical scheme that its technical problem adopted:

A kind of radiator structure of LED street lamp; Comprise lampshade, the lampshade front is provided with the LED light emitting source, and the lampshade back side is provided with radiating fin; Said radiating fin comprises horizontal fin and vertical fin; The parallel lampshade back side that is distributed in of said horizontal fin, laterally stretch out outside the lampshade at the fin two ends, and said vertical fin is perpendicular and divide horizontal fin equally with horizontal fin.

As the further improvement of such scheme, said radiating fin and lampshade are one-body molded.

As the further improvement of such scheme, said radiating fin is fixed on the lampshade back side.Further, said radiating fin directly is fixed on the lampshade back side, is provided with fin between perhaps said radiating fin and the lampshade.

Further improvement as such scheme has been wholely set framework on the said radiating fin, and frame loops is formed the air-flow through hole around the radiating fin setting and with radiating fin.

As the further improvement of such scheme, said lampshade is provided with the groove position of placing battery.

The beneficial effect of the utility model is: the radiating fin among the design comprises horizontal fin and vertical fin; The horizontal parallel lampshade back side that is distributed in of fin; Vertical fin and horizontal fin are perpendicular and divide horizontal fin equally, and integral body is fish bone well, distributes rationally; Make heat radiation evenly, and good looking appearance; Simultaneously, laterally stretch out outside the lampshade at the fin two ends, and form the air communication hole with framework, and air can flow front and back, and flow air is taken away heat rapidly, improves the effect of heat radiation.

The specific embodiment

With reference to Fig. 1, Fig. 2; The radiator structure of a kind of LED street lamp of the utility model comprises lampshade 1, and lampshade 1 front is provided with LED light emitting source 5; Lampshade 1 back side is provided with radiating fin 2; Radiating fin 2 and lampshade 1 are one-body molded or be fixed on lampshade 1 back side, and radiating fin 2 comprises horizontal fin 21 and vertical fin 22, said horizontal fin 21 parallel lampshade 1 back sides that are distributed in; Laterally stretch out outside the lampshade 1 at fin 21 two ends, and said vertical fin 22 and horizontal fin 21 are perpendicular and divide horizontal fin 21 equally; Be wholely set framework 3 on the radiating fin 2, framework 3 is provided with around radiating fin 2 and forms air-flow through hole 4 with radiating fin 2.Radiating fin 2 integral body among the design are fish bone well, distribute rationally, and heat radiation is even, and good looking appearance; Simultaneously, air can flow through air-flow through hole 4 front and back, and flow air is taken away heat rapidly, improves the effect of heat radiation.

Further, radiating fin 2 can directly be fixed on lampshade 1 back side, perhaps between radiating fin 2 and lampshade 1, is provided with fin.

In addition, lampshade 1 is provided with the groove position 11 of placing battery.

With reference to Fig. 3, one of preferred embodiment of the utility model, lampshade 1 adopt the good metal material of thermal conductivity to make, and are equipped with high-power LED light emitting source 5 in lampshade 1 the place ahead, and battery is installed in 11 li of groove positions, adopts the lower cover that is fixed on the lampshade 1 to seal.

With reference to Fig. 4, another preferred embodiment of the utility model is equipped with a plurality of low power LED light emitting sources 5 before the lampshade 1, adopts the little low power LED light emitting source 5 of caloric value integrated as road-light light-source, and light efficiency does not subtract, and radiating effect is better.

The above is merely the preferential embodiment of the utility model; The utility model also comprises the other two kinds of preferred embodiments among Fig. 5 to Fig. 8; In addition, as long as realize that with basic identical means the technical scheme of the utility model purpose all belongs within the protection domain of the utility model.
