Abstract

The utility model discloses a circulation heat-radiation system of a light emitting diode (LED) street lamp. The LED street lamp comprises a lamp housing, a support pole, a heating board, an LED lamp and a power supply. An evaporating tube, a downcomer, a riser and the heating board form a closed heat-radiation circulation circuit, and a cooling medium is filled in the heat-radiation circulation circuit, thereby effectively solving the problem of heat radiation of the LED street lamp illumination and further prolonging service life of the street lamp. Simultaneously, the street lamp has high heat-radiation efficiency, light weight and simple structure.

Description

LED street lamp cycle cooling system
Technical field
The utility model relates to a kind of LED street lamp, particularly a kind of LED street lamp cycle cooling system.
Background technology
Progress along with modern civilization, the city illumination development rapidly, various large power energy-saving road lamps competitively come out, high-pressure mercury lamp is once once with than the remarkable energy-conservation advantage of incandescent lamp, covered new round street lamp market, the performance indications of the LED lighting source technology raising that obtains advancing by leaps and bounds in recent years, its luminous efficiency height of this solid state light emitter, color developing is good, response speed is fast, long service life is compared with high-pressure mercury lamp, and LED is more energy-conservation more than 60% than it, can predict, following road lamp energy-saving transformation must will be taken as the leading factor with LED, and LED when the light fixture, mainly need handle heat radiation and luminous intensity distribution two large problems as light source applications of new generation well.
At present, occurred the high-power LED street lamp product on the market, utilized high-power LED light source to replace the light source of conventional road lamp, except will solving the luminous intensity distribution problem, heat dissipation problem is the key issue that LED street lamp product needed solves.General LED street lamp is in order to solve heat dissipation problem, and the radiator structure design is complicated, consumptive material is many, structure is heavy, and its radiating effect is also desirable not to the utmost.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of LED street lamp cycle cooling system, and this road lamp cooling efficient height is in light weight, and simple in structure.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of LED street lamp cycle cooling system, described LED street lamp comprises lamp housing, support column, hot plate, LED lamp and power supply, described lamp housing is fixed on the support column, described hot plate is fixed in the support column below, described LED lamp is fixed in the hot plate below, described lamp housing is made up of evaporation plate and some evaporation tubes, and some evaporation tubes are located between evaporation plate outer surface and the evaporation tube and are interconnected; Also be provided with a tedge in the set lamp housing, tedge one end is communicated with the end sealing of hot plate, and the described tedge other end is communicated with the evaporation tube sealing on evaporation plate top; Described hot plate is hollow form, the other end of hot plate is communicated with the evaporation tube sealing of lamp housing both sides by two down-comers, constitute the heat radiation closed circuit of a sealing between described evaporation tube, down-comer, tedge and the hot plate, and be filled with cooling medium in the heat radiation closed circuit, after opening the LED lamp, cooling medium heating evaporation in hot plate enters the lamp housing top by tedge, reenters hot plate through evaporation tube cooling back by down-comer at the lamp housing outer surface, forms the circulation heat radiation.
As further improvement of the utility model, described evaporation tube is snakelike arrangement and is uniformly distributed in the evaporation plate outer surface, and the snakelike distribution of evaporation tube has effectively increased the effect of medium heat radiation, makes the medium cooling more abundant.
The beneficial effects of the utility model are: this LED street lamp will constitute a heat radiation closed circuit between the lamp plate in lamp housing and the internal structure, tedge and the down-comer, and in closed circuit, charge into cooling medium, effectively solved the heat dissipation problem of LED street lighting, thereby improved the service life of street lamp, this road lamp cooling efficient height simultaneously, in light weight, and simple in structure.
