Abstract
The invention provides a radiating module for a light-emitting diode (LED) street lamp. The radiating module for the LED street lamp is characterized in that: a heat pipe technology is used for conducting heat produced by LED lamp beads to a side face of the module through a heat pipe at a high conducting speed and dissipating the heat through a radiator on the side face. In the core of the structure, the heat is conducted through the heat pipe and is directly dissipated through a side wall of the module. During actual use, air convection can be formed on the side face, and the radiating speed is increased. However, the traditional integral radiating structure cannot form the air convection, and the temperature of the radiator can be reduced only by ambient temperature.
Description
Technical field
The present invention relates to be used for the core component cooling system of the LED street lamp of road lighting, belong to semiconductor lighting technology and new material application.
Background technology
Now the LED street lamp begins large-area popularization and application, and the street lamp product of most enterprise production manufacturings all is based on and uses aluminum alloy materials to do shell and dispel the heat with the direct-connected mode of LED lamp pearl.LED street lamp shell is a radiator, slow the coming out of heat that most of lamp pearl is produced.This shell is as radiator, and effect is undesirable, and in rugged environment, dust accretions causes heat to dissipate in the shell of heat radiation.LED lamp pearl is worked under this environment, can reduce LED lamp pearl reliability and service life greatly, has restricted the development and the use of LED street lamp, and energy-saving and emission-reduction can not large-arealy be promoted.
Summary of the invention
For solving the technical problem of above-mentioned existence; The object of the present invention is to provide a kind of heat radiation module; The method that original centralized use shell is made radiator makes the method for dispelling the heat with several modules into, and in module, adds heat pipe and export to the periphery of module to the heat that produces earlier, accelerates radiating rate through the periphery and the cross-ventilation of module; Cooling fluid in the heat pipe is utilized the sweat cooling principle simultaneously; Because of the heat pipe two ends temperature difference is very big, heat is conducted fast temperature is descended rapidly, thereby reach the purpose of cooling.Utilize the module form, solve the existing problem of original employed integral heat sink.LED road lamp cooling problem is solved at all.
The object of the invention, will realize through following technical scheme:
A kind of module that is used for the LED road lamp cooling is characterized in that: the module of the said a kind of LED of being used for road lamp cooling is circle or square;
Further, said module main body adopts integrated aluminium alloy compression casting moulding;
Further, module is embedded with LED lamp pearl and is welded on the aluminium base;
Further, heat pipe is assemblied in the aluminium base bottom and closely connects into the S shape with the module inwall;
Further, in the heat pipe cooling fluid is arranged;
Further: module is the core component to LED lamp pearl heat radiation, and heat exports to the radiator in the outside in the module, and heat is distributed.
Benefit of the present invention is embodied in:
1. LED road lamp cooling module structurally thoroughly changes existing heat dissipation technology problem, guarantees the service life of led light source, reduces maintenance cost;
2. improve the flexibility of using, reduced development cost and mould input;
The LED street lamp is standardized into is possible;
4. large tracts of land is promoted easily, and application can expand to pavement, square, garden, highway, tunnel etc.;
Description of drawings:
Fig. 1 is the structural representation of the present invention's " a kind of module of the LED of being used for road lamp cooling ";
Fig. 2 is the vertical view of the present invention's " a kind of module of the LED of being used for road lamp cooling ";
Fig. 3 is the upper cover plate of the present invention's " a kind of module of the LED of being used for road lamp cooling ";
Fig. 4 is the lower cover of the present invention's " a kind of module of the LED of being used for road lamp cooling ".
The specific embodiment;
The present invention discloses a kind of module of the LED of being used for road lamp cooling.Wherein upper cover plate 1 is fixed on glass above the module, and materials such as LED lamp pearl, heat pipe 4 are housed in module 2 bodies.Connect behind the LED lamp pearl circuit through base plate 3 connecting line is drawn from 5.
Utilize hot pipe technique, the heat that is produced LED lamp pearl is transmitted to the side of module 2 through heat pipe with high conduction speed, and radiator through the side 6 distributes heat.
The core of this structure is that directly the sidewall through module dispelled the heat after heat was derived through heat pipe.And in actual use, the side can form cross-ventilation, accelerates the speed of heat radiation.And traditional integral heat sink structure is the convection current that can't form air, can only reduce the temperature of radiator through environment temperature.
