Abstract
The utility model relates to the LED field, in particular to a heat radiation improved structure for a high-power LED street lamp. The heat radiation improved structure comprises a lamp socket, a LEDarranged in the lamp socket and a lamp cover. The LED is packaged on a heat radiation basal plate, then the heat radiation basal plate is arranged in the lamp socket, and cooling fins and support heatconducting ridges are arranged at the back face of the lamp socket. the heat radiation basal plate, cooling fins and support heat conducting ridges are coated with a heat conducting nanometer coatinglayer. The utility model, adopting the technical project, solves the problem the heat radiation of the present high-power LED street lamp is poor, the heat is dissipated by the heat radiation basal plate, the cooling fins and the air convection, the heat radiation surface can be increased and the heat radiation efficiency can be improved, thus the high-power LED street lamp of the utility model has long life, high brightness, shock resistance and shock resistance.
Description
Technical field
The utility model relates to the LED field, and the heat radiation that relates in particular to high-power LED street lamp improves structure.
Background technology
LED is the abbreviation of English light Emitting Diode, and promptly light emitting diode is a kind of semiconductor solid luminescence device.Have luminous efficiency height, little power consumption, long service life, the high characteristics of simple, the luminous uniformity of control circuit.The relative conventional incandescent of the heating of LED is lower, but if it still is high adopting its caloric value of great power LED, if not in addition control can have influence on life-span and the light decay of LED.In addition, the street lamp long term exposure is in outdoor, and therefore requiring its structure is the hermetically-sealed construction of waterproof and dustproof, and this has just aggravated the accumulation of heat of LED street lamp.
The utility model content
At above-mentioned these problems, the utility model proposes a kind of high-power LED street lamp heat radiation improvement structure and solve.
The technical solution of the utility model is:
High-power LED street lamp heat radiation of the present utility model improves structure, comprises lamp socket, is arranged at LED and lampshade in the lamp socket.Described LED is packaged on the heat-radiating substrate, and heat-radiating substrate is installed in the lamp socket again, and the lamp socket back side is provided with radiating fin and supports the heat conduction ridge, and its heat-radiating substrate, radiating fin and support heat conduction ridge all have the high heat conducting nano coating.
Further, described radiating fin is that plural pieces is transversely arranged in the middle part at the lamp socket back side, and supporting the heat conduction ridge is 2 positions, front and back, both sides that vertically are distributed in the lamp socket back side.
The utility model adopts as above technical scheme, has solved the problem of existing high-power LED street lamp poor heat radiation, and heat-radiating substrate and shell radiating fin and cross-ventilation heat radiation by being laid with the heat conducting nano coating increase radiating surface, and radiating efficiency is provided.Make high-power LED street lamp of the present utility model have the long-life, high brightness, vibration resistance, shock proof advantage.
Description of drawings
Fig. 1 is the upward view of the utility model structure;
Fig. 2 is the side view of the utility model structure;
Fig. 3 is the vertical view of the utility model structure.
The specific embodiment
Now with the specific embodiment the utility model is further specified in conjunction with the accompanying drawings.
Consult Fig. 1, Fig. 2, three-view diagram shown in Figure 3, high-power LED street lamp heat radiation of the present utility model improves structure, comprises lamp socket 1, is arranged at LED4 and lampshade 3 in the lamp socket 1.Described LED4 directly is packaged on the heat-radiating substrate 2, and LED4 is to be coated with the heat-conducting glue realization by adding with close contact of heat-radiating substrate 2, and heat-radiating substrate 2 is installed in the lamp socket 1 again, and lamp socket 1 back side is provided with radiating fin 11 and supports heat conduction ridge 12.LED4 just is delivered to lamp socket 1 and lamp socket 1 back side again by heat-radiating substrate 2 and is provided with radiating fin 11 and supports heat conduction ridge 12 like this.Described heat-radiating substrate 2, radiating fin 11 and support heat conduction ridge 12 all have the high heat conducting nano coating, further strengthen radiating effect.
Described radiating fin 11 is that plural pieces is transversely arranged in the middle part at lamp socket 1 back side, radiating fin 11 and cross-ventilation heat radiation; Support heat conduction ridge 12 and be positions before and after 2 both sides that vertically are distributed in lamp socket 1 back side, play heat radiation simultaneously and support the effect of lamp socket 1, can vibration resistance, shock resistance.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; in the spirit and scope of the present utility model that do not break away from appended claims and limited; can make various variations to the utility model in the form and details, be protection domain of the present utility model.
