Abstract
The invention discloses a light-emitting diode (LED) street lamp with a built-in air cooling radiator. The LED street lamp comprises an LED chip, an LED chip fixing plate, a heat conduction pipe, radiating fins and a fan. The LED chip is fixed on the LED chip fixing plate, the LED chip fixing plate is connected with the radiating fins on the lower portion of the LED chip fixing plate through the heat conduction pipe, a heat transfer medium is arranged in the heat conduction pipe, and the fan is arranged on the lower portions of the radiating fins. By means of the structure, the LED street lamp with the built-in air cooling radiator has the advantages of being high in radiating, high in brightness, good in color temperature, long in service life and simple in structure under same power.
Description
Technical field
The present invention relates to a kind of LED street lamp, relate in particular to a kind of street lamp with built-in wind cooling radiator.
Background technology
LED is being widely used in illuminating industry as the new generation of green energy, as new generation of green environment protection solid lighting source, has become the focus that people pay close attention to.It has few, photochromic pure, all solid state, a series of advantages such as quality is light, volume is little, environmental protection of power consumption.Have portion of energy when LED is luminous and be converted into heat, therefore, the led chip temperature is raise.And temperature to the influence of the service behaviour of led chip greatly, and high temperature can cause the photon of chip outgoing to reduce, and the colour temperature quality descends, and it is aging to accelerate chip, shortens serious consequences such as device lifetime.Therefore, for guaranteeing the LED operate as normal, the heat that comes out in time must be distributed.At present, it is more and more that high-power LED chip is used, and great power LED can only be converted into luminous energy with the input power of about 10-15% according to data, and remaining 85-90% is converted into heat energy, and therefore, it is very important that heat dissipation problem seems.
As everyone knows, radiator and lamp housing that LED street lamp in the market adopts are the design of one, numerous slot type louvres namely is set on lamp housing top, the heat that led chip is sent, under the drive of natural wind, distribute by these slot type louvres, the LED street lamp of this radiating mode in order to improve radiating effect, needs bigger lamp housing on the one hand; Be exactly that radiating effect is bad on the other hand, influence its service life.
Summary of the invention
The purpose of this invention is to provide a kind of built-in wind cooling heat radiator type LED street lamp, under the situation of equal-wattage, it has rapid heat dissipation, and brightness is big, and colour temperature is good, long service life, advantage simple in structure.
Another object of the present invention also provides the heat transfer medium in a kind of heat pipe.
The objective of the invention is to be achieved through the following technical solutions, this built-in wind cooling heat radiator type LED street lamp comprises led chip, led chip fixed head, heat pipe, fin, fan, described led chip is fixed on the led chip fixed head, described led chip fixed head links to each other with the fin of its underpart by heat pipe, be provided with heat transfer medium in the described heat pipe, the bottom of described fin is provided with fan.
Heat transfer medium in the described heat pipe is common pure water and methanol mixture, and described common pure water is 3: 1 with the ratio of methyl alcohol.
Described heat transfer medium accounts for 0.1% of heat pipe inner volume.
Four angles of described fin 4 are provided with the support and connection leg that elastomeric material is made, and link to each other with four angles of fan 5 by these four support and connection legs.
The heat pipe of described connection led chip fixed head and fin is two.
Described fin is fence type.
Be provided with certain intervals between described led chip fixed head, fin, the fan, so that ventilation and heat.
Be connected by four angles between described fin and the fan.
Described led chip links to each other with circuit controller by lead.
Described fan links to each other with power supply by lead.
During work, the heat that led chip produces is passed to fin by led chip fixed head, heat pipe, and the cold wind that is positioned at the fan generation of fin bottom blows away the heat on the fin, improves radiating effect.
Another embodiment of the invention is that the led chip fixed head directly is fixed on the fin, and the bottom of fin is provided with fan, does not need heat pipe to conduct heat.
Beneficial effect of the present invention: adopt the lamp housing heat radiation to compare with traditional LED lamp, what built-in wind cooling heat radiator type LED lamp adopted is the design that radiator separates with lamp housing, good heat dissipation effect not only, long service life, and it is simple in structure, installation and maintenance are convenient, and particularly the LED lamp of different capacity can install in a general lamp housing, and lamp housing is not had more restriction.
