Abstract
The invention relates to a bidirectional ventilated heat dissipation structure of a lamp. The bidirectional ventilated heat dissipation structure of the lamp comprises a sectional material heat dissipation body which comprises a front face and a back face; the sectional material heat dissipation body is a plate-shaped sectional material basic body; a plurality of heat dissipation ribs are arranged on the rear face of the sectional material heat dissipation body; a plurality of LED (Light Emitting Diode) modules are arranged on the front face of the sectional material heat dissipation body; and ventilated grooves are formed between adjacent LED modules. As an optimization, the sectional material heat dissipation body is made of aluminum or aluminum alloy. According to the bidirectional ventilated heat dissipation structure of the lamp, an aluminum sectional material heat dissipation structure is used, the number of the modules can be suitably selected according to different sized power to decide the length of the sectional material heat dissipation body, grooves which enable air on the rear portion of the sectional material heat dissipation body to be performed convection are formed between the two adjacent modules, the heat dissipation effect of the lamp achieves the best, and accordingly the lamp service life is effectively prolonged.
Description
Technical field
The invention belongs to lighting technical field, be 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 present most LED street lamp adopted is aluminium die casting shell integral structure, though 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.
Occurred the street lamp of some similar module radiator structures in the market, but all belonged to unidirectional (being heatsink transverse) radiating mode, effect is general.
Summary of the invention
The objective of the invention is at above-mentioned the deficiencies in the prior art, a kind of light fixture ventilation bidirectional cooling structure with bidirectional cooling function is provided.
For achieving the above object, the technical solution used in the present invention 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 the adjacent described LED module.
Further, the described section bar radiator section bar radiator that is aluminum or aluminum alloy.
Further, the number of described LED module is 4.
The invention has the beneficial effects as follows: the present invention has adopted the aluminium section bar radiator structure, it not only can come the quantity of suitable selection module according to the power of different sizes, and then reserve the length of section bar, also between every adjacent two modules, increased the cross-ventilation groove with the section bar back, this bidirectional cooling mode makes the radiating effect of light fixture reach best, thereby has prolonged the service life of light fixture effectively.
Description of drawings
Fig. 1 is the structure schematic diagram of the section bar radiator of light fixture ventilation bidirectional cooling structure of the present invention.
Fig. 2 is the Facad structure schematic diagram of the section bar radiator of light fixture ventilation bidirectional cooling structure of the present invention.
Among the figure, 1-section bar radiator, 2-radiating ribs, 3-LED module, 4-ventilation slot.
The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples the present invention is described in further detail.Should be appreciated that specific embodiment described herein only in order to explaining the present invention, and be not used in restriction the present invention.
Light fixture ventilation bidirectional cooling structure of the present invention comprises the section bar radiator that is provided with front and back, and described section bar radiator is flat section bar matrix.Fig. 1 is the structure schematic diagram of the section bar radiator of light fixture ventilation bidirectional cooling structure of the present invention, and as shown in Figure 1, the back side of section bar radiator 1 is provided with some radiating ribs 2.Fig. 2 is the Facad structure schematic diagram of the section bar radiator of light fixture ventilation bidirectional cooling structure of the present invention, and as shown in Figure 2, the front of section bar radiator 1 is equipped with four groups of LED modules 3, is provided with ventilation slot between the adjacent LED module 3.As preferably, the section bar radiator that described section bar radiator is aluminum or aluminum alloy.
The present invention has adopted the aluminium section bar radiator structure, it not only can come the quantity of suitable selection digital-to-analogue group according to the power of different sizes, and then reserve the length of section bar, also between every adjacent two modules, increased the cross-ventilation groove with the section bar back, this bidirectional cooling mode makes the radiating effect of light fixture reach best, thereby has prolonged the service life of light fixture effectively.
The present invention 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 above is preferred embodiment of the present invention only, is not to limit practical range of the present invention; If do not break away from the spirit and scope of the present invention, the present invention is made amendment or is equal to replacement, all should be encompassed in the middle of the protection domain of claim of the present invention.
