Description
Technical field
The present invention relates to a kind of street lamp, especially a kind of LED street lamp, specifically a kind of LED street lamp with cooling system with internal circulation.
Background technology
Large power white light LED is a kind of novel semi-conductor solid light source, has that security reliability is strong, power consumption is little, luminous efficiency is high, applicability is strong, good stability, response time weak point, color changeableization, helps the environmental protection advantage.Its performance is just constantly perfect, gets into the practical stage.But along with the increase of LED power, the heat that led chip distributes is more and more, and the heat dissipation problem of LED is more and more outstanding.Through a large amount of retrievals, mainly in the encapsulation of LED, consider at present about practical writing Zhanghe patent of LED heat radiation.Cooling mechanism comprises active heat removal and passive heat radiation simultaneously.The traditional heat-dissipating method has: air-cooled, liquid cooling, semiconductor refrigerating etc.Now some new method is also put forward successively, such as ultrasonic heat dissipation technology, superconduction heat dissipation technology and with multiple heat dissipating method effective integration among a device.But from the design and the manufacturing of present LED street lamp, how the life-span of a heat radiation reliably and raising LED street lamp is provided is a key issue.Although simultaneously at present the structure about the LED street lamp has certain company standard and national standard, attempting to do little change from the transitional street lamps structure, to directly apply to the thinking of heat radiation and application of LED street lamp then few.The present invention attempts to utilize peripheral spaces such as street lamp post, sets up the heat sink conception of LED street lamp, improves the radiating efficiency of street lamp and the life-span of street lamp.
Summary of the invention
The objective of the invention is the defective to prior art, provide a kind of active heat removal is integrated in the street lamp, utilize the LED street lamp of band cooling system with internal circulation of the space heat elimination of lamp stand and lamp bracket.
The objective of the invention is to solve through following technical scheme:
A kind of LED street lamp with cooling system with internal circulation comprises base 12, lamp stand 11 and lamp bracket 3, fixedly installs lamp stand 11 on the base 12; One end of the upper end of lamp stand 11 and lamp bracket 3 is fixedly linked; The other end of lamp bracket 3 is provided with light fixture 14, is provided with thermal conductive substrate 13 in the light fixture 14, is provided with circulating heat pipe 4 in the described lamp bracket 3; The two ends of circulating heat pipe 4 link to each other with delivery port with the water inlet of the water tank that is positioned at lamp stand 11 8 respectively, and circulating heat pipe 4 is provided with kinetic pump 7; The lower surface of said thermal conductive substrate 13 is equipped with LED particle 5, and upper surface and circulating heat pipe 4 are close to.
The upside of said lamp bracket 3 is provided with fan 2.
Described water tank 8 is positioned on the support 9 of lamp stand 11 upper ends, and the side of water tank 8 is fixedly linked through the side of bolt 10 with lamp stand 11.
Be provided with runner 1 in the described circulating heat pipe 4, being filled with heat-conducting medium in the runner 1 is liquid state or gaseous medium.
Described light fixture 14 comprises lampshade 6, and described lampshade 6 is installed on the lamp bracket 3.
The present invention compares prior art has following advantage: the shell of street lamp is combined with the heat abstractor design; In the process that the LED street lamp is changed, only need to change led chip, made things convenient for the maintenance of LED street lamp; And greatly improved radiating effect, prolonged the life-span of street lamp greatly.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention.
Accompanying drawing 2 is node temperature test curves of LED street lamp of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
As shown in Figure 1:
A kind of LED street lamp with cooling system with internal circulation; Fixedly install lamp stand 11 on the base 12; One end of the upper end of lamp stand 11 and lamp bracket 3 is fixedly linked; The other end of lamp bracket 3 is provided with light fixture 14; Be provided with thermal conductive substrate 13 in the light fixture 14, thermal conductive substrate 13 can adopt with aluminium base be main metal-core printed circuit board (MCPCB), pottery, DBC or composite metal substrate with the raising heat conductivility, LED particle 5 is installed on the thermal conductive substrate 13; Thermal conductive substrate 13 be installed in that circulating heat pipes 4 in the lamp bracket 3 fit so that the heat that LED particle 5 is produced is transmitted to the surface of circulating heat pipe 4 fast through thermal conductive substrate 13, take away through the recirculated water that flows in the runner in the circulating heat pipe 41.During practical implementation, flowing liquid also can be other refrigerant except for the water in the runner 1 (being the tube chamber of circulating heat pipe 4); Like air-conditioning refrigerant; Except being the liquid, also can be the gas (like nitrogen) of good heat conductivity, the temperature of LED particle 5 is delivered on the circulating heat pipe 4 through thermal conductive substrate 13; The two ends of circulating heat pipe 4 link to each other with delivery port with the water inlet of the water tank that is positioned at lamp stand 11 8 respectively; Water tank is fixedly linked through bolt 10 and the side of support 8 with lamp stand 11, and cooling medium flows between lamp bracket shell 3 and water tank 8 through the kinetic pump 7 that is arranged on the circulating heat pipe 4, and lamp bracket 3 upsides are provided with fan; To carry out cold moving to circulating heat pipe through fan 2, the heat in the circulating heat pipe will be delivered to peripheral space.The lampshade 6 of lamp bracket 3 downsides is unidirectional lens, and the light that only allows LED particle 5 to send passes through, and has reduced the lamp interior temperature.
