Abstract
The utility model discloses an LED street lamp heat radiating structure. Heat radiating fin sets are vertically distributed on the reverse side of an LED street lamp body. Heat radiating channels are formed among heat radiating fins which belong to the heat radiating fin sets, and a reinforced rib is arranged on each heat radiating fin. By the adoption of the LED street lamp heat radiating structure, the heat radiating channels are formed among the heat radiating fins, so that natural wind can enter the heat radiating channels, ventilation is good, heat generated when an LED is operated can be effectively radiated, and the service life of an LED light source is prolonged.
Description
Technical field
The utility model relates to lighting field, relates in particular to a kind of LED road lamp cooling structure.
Background technology
Just at present, the LED lighting is the general designation of LED light fixture, and along with the further maturation of LED technology, LED will obtain more better development in the lighting field of designing and developing, room.The room Design of Luminaires of 21 century will be to be main flow with the LED Design of Luminaires, demonstrates fully the illumination development trend of energy-conservationization, healthization, art up and hommization simultaneously, becomes the leading of room light culture.In new century, the LED lighting will illuminate everyone room, changes everyone life, becomes once great change of light fixture development and Design.
The LED light fixture amasss little light weight, can select for use different photochromic LED to be combined into the soft various modules of illumination, is installed in arbitrarily in the room, and the light source of room lighting may derive from ground, metope, windowsill, furniture, jewelry etc.Therefore, the illumination of following room will no longer be confined to single light fixture, and will be converted into the shadowless lamp of the integral illumination effect of no luminaire tool sense by single lamp lighting.Different photochromic and brightness can produce different influences to people's physiology with psychology, and people do not need very bright white light under many circumstances, the needs of the more suitable physiology of the light of possible gold-tinted or other colors and psychology.Three-primary color LED can be realized continuous transformation and the selection of brightness, gray scale, color, makes illumination expand to the light of multiple color from the white light on the universal significance.
But in the prior art, the LED street lamp has tangible power savings advantages; Through being applied to the check of the experiment situation in the street lamp in recent years, all there is problem in various degree in most LED street lamp; Product fails to take into full account for the requirement of led light source condition of work when design mostly; Cause product to cause light attenuation seriously to extinguish even in use; This one of them sixty-four dollar question is exactly the radiator structure of LED street lamp; Current, heat radiation is the technical problem that the LED street lamp wants emphasis to solve; Because the temperature resistant capability of LED own is poor, so effectively being dispersed in the air, goes the heat that produces luminous tube must be worked the time, guarantee chip operation under the temperature environment of safety, LED lamp ability is real like this embodies long-life advantage.The technological deficiency that the radiator structure of current LED street lamp exists becomes those skilled in the art's technical problem anxious to be solved.
The utility model content
The purpose of this utility model is that a kind of LED road lamp cooling structure will be provided.
According to an aspect of the present utility model, a kind of LED road lamp cooling structure is provided, vertically be distributed with the radiating fin group at the LED road lamp body back side, constitute heat dissipation channel between the radiating fin under the radiating fin group, be equipped with reinforcement on each radiating fin.
In some embodiments, be distributed in the radiating fin height at middle part, the lamp body back side greater than the radiating fin height that is distributed in both sides, the lamp body back side, radiating fin group top is circular-arc distribution.
In some embodiments, equidistantly distribute between the radiating fin.
In some embodiments, radiating fin is the circular arc radiating fin.
A kind of LED road lamp cooling structure of the present utility model by constituting heat dissipation channel between the radiating fin, makes natural wind to enter, the well-ventilated, can be effectively work produces to LED heat dissipate, promote the service life of led light source.
Description of drawings
Fig. 1 is the side view of the LED road lamp cooling structure of the utility model one embodiment;
Fig. 2 is the vertical view of the LED road lamp cooling structure of the utility model one embodiment.
The specific embodiment
Shown in Fig. 1-2, the utility model discloses a kind of LED road lamp cooling structure, vertically be distributed with radiating fin group 1 at the LED road lamp body back side, constitute heat dissipation channel between the radiating fin 11 under the radiating fin group, be equipped with reinforcement 2 on each radiating fin, reinforcement 2 plays and supports and fixing effect, can have the radiating fin of preventing 11 distortion, increases the effect of the rigidity of radiating fin 11.
In some embodiments, be distributed in radiating fin 11 height at middle part, the lamp body back side greater than radiating fin 11 height that are distributed in both sides, the lamp body back side, such design has the air-flow overall flow of utilizing in the heat dissipation channel smooth and easy, can effectively take away the heat that radiating fin 11 comes out; Radiating fin group 1 top is circular-arc distribution, can lamp body, LED, radiating fin 11 incidental heats be dissipated, and promote the effect of overall appearance in addition in the mode of maximum area of dissipation thus; Equidistantly distribute between the radiating fin 11, just can realize whole balanced heat radiation, can not occur the effect of heat local accumulation influence heat radiation at lamp body, and cooperate radiating fin group 1 top to be the design of circular-arc distribution, better improve radiating effect; And radiating fin 11 is circular arc radiating fin 11, just can not cause unnecessary damages to the assembler owing to the lofty existence of wedge angle.
A kind of LED road lamp cooling of the utility model structure, radiating principle is: the heat that produces during lamp body conduction LED work, give each radiating fin 11.Because it is outdoor that the utility model is installed in, and by the air current flow of various directions, makes air-flow by heat dissipation channel radiating fin 11 be conducted the heat that and take out of, dissipates.
A kind of LED road lamp cooling of the utility model structure by constituting heat dissipation channel between the radiating fin 11, makes natural wind to enter, can be effectively work produces to LED heat dissipate; In addition, radiating fin 11 is to be equally spaced, so the well-ventilated, radiating effect significantly improves, and adds reinforcement 2 at radiating fin 11 simultaneously, make the rigidity of radiating fin 11 strengthen, practice shows, improvement of some by this, and the radiating effect of LED street lamp is good, luminous stable, and obtained effective guarantee service life.
