The LED streetlamp comprises a connector, a lamp shade and an LED lamp component, wherein one side of the connector is fixed to a lamp pole, one end of the lamp shade is fixed to the other side of the connector, the LED lamp component is fixed below the lamp shade, the lamp shade is composed of a radiating substrate and radiating fins disposed at intervals above the same, and the radiating fins extend along the length direction of the radiating substrate.
Description
Technical field
The utility model relates to field of illumination lamp technology, particularly a kind of LED street lamp.
Background technology
Because low, the environmental protection, energy-conservation of long service life, energy consumption of LED light emitting diode, the traditional light fixture of ashamed replacement has pursued as the LED light fixture of light source in society now, as the LED street lamp, general LED street lamp structure mainly is made up of housing and the LED light fixture be located in the housing, this LED street lamp has low, the effect of saving energy of energy consumption.But, a large amount of heat that can produce during owing to the work of LED lamp, if the heat that produces can not distribute as soon as possible, being deposited in led light source heat on every side not only can influence lamp luminescence efficient, also can reduce reliability of products, shorten its service life.So being illuminating industry, the heat dissipation problem of LED street lamp presses for the problem of solution.At present, the radiating mode of LED street lamp mainly contains: install fan forced heat radiation, heat pipe and loop heat pipe heat radiation etc. additional.Install fan forced heat radiation mode system complex additional, reliability is low, heat pipe and loop heat pipe radiating mode cost height.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, thereby the LED street lamp of a kind of simple in structure, low cost of manufacture, good heat dissipation effect, long service life is provided.
The technical scheme that the utility model adopted is such: a kind of LED street lamp, comprise link, lampshade, LED lamp group, described link one side is fixedly arranged on the lamp stand, described lampshade one end is fixedly arranged on the opposite side of link, described LED lamp group is fixedly arranged on the lampshade below, the fin that described lampshade is located at the heat-radiating substrate top by heat-radiating substrate and interval is formed, and described each fin is stretched along heat-radiating substrate length direction edge.
Further: described lampshade is installed with decorative shell away from that side of link.
Further: the material of described lampshade is a copper.
Further: described link, lampshade and decorative shell from left to right connect as one by the bolt gap.
By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: the utility model LED street lamp, the fin that its lampshade is located at the heat-radiating substrate top by heat-radiating substrate and interval is formed, heat-radiating substrate becomes for the high conductivity material copper with fin, the heat that is produced in the time of effectively absorbing the illumination of LED lamp group.This Novel LED street lamp, behind the heat that the heat-radiating substrate of its lampshade is produced when absorbing the illumination of LED lamp group, be distributed to heat in the atmosphere fast by the fin on the heat-radiating substrate again, because fin and heat-radiating substrate dispel the heat simultaneously, have increased area of dissipation greatly, compared with similar products, under the prerequisite that manufacturing cost does not improve substantially, radiating effect increases substantially, and has guaranteed the operating efficiency and the stability of LED lamp effectively, has also prolonged the service life of LED lamp simultaneously.
Description of drawings
Fig. 1 is the utility model embodiment sectional structure chart;
Fig. 2 is the utility model embodiment upward view;
Fig. 3 is the utility model Embodiment B-B cutaway view.
The specific embodiment
Further specify the utility model below in conjunction with the drawings and specific embodiments.
As Fig. 1, Fig. 2, Fig. 3, the utility model discloses a kind of LED street lamp, comprise link 1, lampshade 2,4 groups of LED lamp groups 3, one side of described link 1 is fixedly arranged on the lamp stand, described lampshade 2 one ends are fixedly arranged on the opposite side of link 1, described 4 groups of LED lamp groups 3 are fixedly arranged on lampshade 2 downsides, the fin 22 that described lampshade 2 is located at heat-radiating substrate 21 tops by heat-radiating substrate 21 and interval is formed, described each fin 22 is stretched along heat-radiating substrate 21 length directions edge, described heat-radiating substrate 21 and each fin 22 integrally casting moulding, described heat-radiating substrate 21 is made for high conductivity material copper or aluminium with fin 22, the heat that is produced in the time of effectively absorbing the illumination of LED lamp group.This Novel LED street lamp, behind the heat that the heat-radiating substrate 21 of its lampshade 2 is produced when absorbing the illumination of LED lamp group, be distributed to heat in the atmosphere fast by the fin on the heat-radiating substrate again, because fin and heat-radiating substrate dispel the heat simultaneously, have increased area of dissipation greatly, compared with similar products, under the prerequisite that manufacturing cost does not improve substantially, radiating effect increases substantially, and has guaranteed the operating efficiency and the stability of LED lamp effectively, has also prolonged the service life of LED lamp simultaneously.
Described lampshade 2 is provided with two wiring channels 23, makes things convenient for LED lamp group to connect up, and cable is set in the wiring channel 23 during use.
Described lampshade 2 is installed with decorative shell 4 on that side away from link 1, and decorative shell 4 also plays protection LED lamp except playing decoration function.
Described link 1, lampshade 2 and decorative lamp frame 3 are connected to one by bolt 5, and the fixed connection place between its three is provided with gap 6, this design, and the convection current of favourable raising radiator surrounding air on the one hand promotes heat radiation; Dust of piling up between each fin and rainwater also can fall by this gap 6 rows on the other hand.
More than show and described basic principle of the present utility model and principal character and advantage thereof; the technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the explanation just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
