Abstract
The utility model relates to a ventilating two-way heat radiation structure of a lamp. The structure comprises a sectional material radiator provided with a front face and a back face. The sectional material radiator is a tabulate sectional material base body. The back face of the sectional material radiator is provided with a plurality of radiating ribs, and the front face of the sectional material radiator is provided with a plurality of LED modules. A ventilating groove is formed between every two adjacent LED modules. Preferentially, the sectional material radiator is made of aluminum or aluminum alloy. The ventilating two-way heat radiation structure of the lamp is the section aluminum radiator structure, the number of the modules can be appropriately determined according to different power values, and then the sectional material length is determined; an air convection groove opposite to the sectional material is additionally between every two adjacent modules. According to the ventilating two-way heat radiation structure of the lamp, due to the two-way heat radiation mode, the heat radiating effect of the lamp is made to best, and therefore the service life of the lamp is effectively prolonged.
Description
Technical field
The utility model belongs to lighting technical field, is specifically related to a kind of light fixture ventilation bidirectional cooling structure.
Background technology
The fine or not direct relation of radiating effect the service life of LED light fixture.What current most LED street lamp adopted is aluminium die casting shell integral structure, although waterproof effect is pretty good, is accompanied by the increase of power, and the heat-sinking capability of light fixture presents overload state, causes seriously shorten the service life of light fixture.
The street lamp that some similar module radiator structures occurred in the market, but all belong to unidirectional (being heatsink transverse) radiating mode, effect is general.
The utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, and a kind of light fixture ventilation bidirectional cooling structure with bidirectional cooling function is provided.
For achieving the above object, technical solution adopted in the utility model is as follows.
A kind of light fixture ventilation bidirectional cooling structure, comprise the section bar radiator that is provided with front and back, described section bar radiator is flat section bar matrix, and the back side of described section bar radiator is provided with some radiating ribs, and the front of described section bar radiator is equipped with some LED modules.
Further, be provided with ventilation slot between adjacent described LED module.
Further, the section bar radiator that described section bar radiator is aluminum or aluminum alloy.
Further, the number of described LED module is 4.
The beneficial effects of the utility model are: the utility model has adopted the aluminium section bar radiator structure, it not only can carry out according to the power of different sizes the quantity of suitable selection module, and then reserve the length of section bar, also between every adjacent two modules, increased the air convection groove with the section bar back, this bidirectional cooling mode makes the radiating effect of light fixture reach best, thereby has effectively extended the service life of light fixture.
The accompanying drawing explanation
The structure schematic diagram of the section bar radiator that Fig. 1 is the utility model light fixture ventilation bidirectional cooling structure.
The Facad structure schematic diagram of the section bar radiator that Fig. 2 is the utility model light fixture ventilation bidirectional cooling structure.
In figure, 1-section bar radiator, 2-radiating ribs, 3-LED module, 4-ventilation slot.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is described in further detail.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Light fixture ventilation bidirectional cooling structure of the present utility model comprises the section bar radiator that is provided with front and back, and described section bar radiator is flat section bar matrix.The structure schematic diagram of the section bar radiator that Fig. 1 is light fixture ventilation bidirectional cooling structure of the present utility model, as shown in Figure 1, the back side of section bar radiator 1 is provided with some radiating ribs 2.The Facad structure schematic diagram of the section bar radiator that Fig. 2 is the utility model light fixture ventilation bidirectional cooling structure, as shown in Figure 2, the front of section bar radiator 1 is equipped with four groups of LED modules 3, between adjacent LED module 3, is provided with ventilation slot.As preferably, the section bar radiator that described section bar radiator is aluminum or aluminum alloy.
The utility model has adopted the aluminium section bar radiator structure, it not only can carry out according to the power of different sizes the quantity of suitable selection digital-to-analogue group, and then reserve the length of section bar, also between every adjacent two modules, increased the air convection groove with the section bar back, this bidirectional cooling mode makes the radiating effect of light fixture reach best, thereby has effectively extended the service life of light fixture.
The utility model has adopted module and ventilation bidirectional cooling structure, LED and power supply is played a very good protection, thereby ensured service life of light fixture.
The foregoing is only preferred embodiment of the present utility model, not be used for limiting practical range of the present utility model; If do not break away from spirit and scope of the present utility model, the utility model is modified or is equal to replacement, all should be encompassed in the middle of the protection domain of the utility model claim.
