Abstract

The utility model discloses an LED streetlamp with a complete heat dissipation structure, and belongs to the technical field of LED illumination. The utility model provides key points as follows: the LED streetlamp includes a heat dissipation base plate, wherein an aluminium base plate is arranged on the lower surface of the heat dissipation base plate, LED lamp beads are distributed and mounted on the aluminium base plate, a reflection cover is arranged around the LED lamp beads, heat dissipation ribs are distributed along the circumference of the reflection cover on the surface of the heat dissipation base plate around the reflection cover, and a secondary optical evening cover is arranged on the heat dissipation ribs outside the reflection cover. The utility model aims to provide the LED streetlamp with the complete heat dissipation structure, which is good at heat dissipation and illumination effects and is used for outdoor road illumination.

Description

A kind of LED street lamp of full radiator structure
Technical field
The utility model relates to a kind of LED lighting, more particularly, relates in particular to a kind of LED street lamp of full radiator structure.
Background technology
Traditional indoor and outdoor illumination adopts incandescent lamp or electricity-saving lamp (neon tube lamp) usually, and its relative energy consumption is higher; Progress along with electronic technology, utilize the lighting of High Power LED (LED) combination more and more general,, have low in energy consumption because LED utilizes the luminescent properties after semiconductor is switched on luminous, the advantage of long service life, thereby become the emerging light source that substitutes the traditional lighting light source.With the light fixture of LED as light source, need to solve heat transfer and heat dissipation problem in the LED use, and the LED single source luminous dazzling, dazzle the eyes and be easy to generate the hot spot deficiency; In particular for the street lamp of road lighting, need work for a long time, caloric value is big, if can not solve heat dissipation problem well, can have a strong impact on the service life of light fixture.Therefore after need improving traditional lamp post structure, could utilize LED as light source.
The utility model content
The technical problems to be solved in the utility model is the above-mentioned deficiency at prior art, and the LED street lamp of the full radiator structure of a kind of heat radiation and good illumination effect is provided.
The technical solution of the utility model is such: a kind of LED street lamp of full radiator structure, comprise heat-radiating substrate, wherein said heat-radiating substrate lower surface is provided with aluminium base, on aluminium base, distribute LED lamp pearl is installed, be provided with reflector in LED lamp pearl periphery, heat-radiating substrate surface in the reflector periphery circumferentially is distributed with radiated rib along reflector, is provided with the even light shield of secondary optics on the radiated rib in the reflector outside.
In the LED street lamp of above-mentioned a kind of full radiator structure, the described heat-radiating substrate back side is distributed with curved heat-dissipating fin.
In the LED street lamp of above-mentioned a kind of full radiator structure, described radiated rib circumferentially is evenly distributed on the heat-radiating substrate along reflector.
After the utility model adopts said structure, by heat-dissipating fin being set at the heat-radiating substrate back side, simultaneously directly at reflector periphery design radiated rib, the heat that is produced when can be with LED luminous transmits heat radiation in the air preferably towards periphery, heat transmission and heat dissipation problem in the use of LED lamp have been solved, thereby can not cause heat accumulation and make the LED lamp be in higher temperature for a long time and work, the LED lamp can be used for a long time, it is simple in structure, has solved the heat transfer and the heat dissipation problem of present high-powered LED lamp lighting effectively; After further improving,, can eliminate luminous dazzling, the deficiency of dazzling the eyes and be easy to generate hot spot of LED lamp source, improve the illuminating effect of light fixture by the even light shield of secondary optics is set.
Description of drawings
The utility model is described in further detail below in conjunction with the embodiment in the accompanying drawing, but do not constitute any restriction of the present utility model.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the upward view of Fig. 1.
Among the figure: heat-radiating substrate 1, aluminium base 2, LED lamp pearl 3, reflector 4, radiated rib 5, the even light shield 6 of secondary optics, heat-dissipating fin 7
The specific embodiment
Consult Fig. 1, shown in Figure 2, the LED street lamp of a kind of full radiator structure of the present utility model, comprise heat-radiating substrate 1, be provided with aluminium base 2 at heat-radiating substrate 1 lower surface, on aluminium base 2, distribute LED lamp pearl 3 is installed, be provided with reflector 4 in LED lamp pearl 3 peripheries, heat-radiating substrate 1 surface in reflector 4 peripheries circumferentially is evenly distributed with radiated rib 5 along reflector 4, radiated rib 5 can distribute the heat that reflector 4 produces in time by cross-ventilation, temperature when guaranteeing light fixture work can be too not high, on the radiated rib 5 in reflector 4 outsides, be provided with the even light shield 6 of secondary optics, it is luminous dazzling to eliminate the LED lamp source, dazzle the eyes and be easy to generate the deficiency of hot spot, improve the illuminating effect of light fixture; Further, be distributed with curved heat-dissipating fin 7, can increase the integral heat sink effect of light fixture at heat-radiating substrate 1 back side, and the curve form of heat-dissipating fin 7, the area of heat radiation can in identical heat-dissipating space, be increased greatly; The overall structure that heat-radiating substrate 1, radiated rib 5 and heat-dissipating fin 7 are formed in one makes things convenient for scheme and processing.
