Abstract
The utility model discloses an air-cooled LED lamp which comprises the following components: an LED chip, an LED chip fixing board, a heat conduction tube, heat radiating fins and a fan. The LED chip is fixed on the LED chip fixing board. The LED chip is connected with the heat radiating fins below the LED chip through the heat conduction tube. The heat conduction tube is internally provided with heat transfer medium. The fan is provided below the heat radiating fins. Because the structure of the utility model is adopted, on a condition of same power, the air-cooled LED lamp has the following advantages: high heat radiation speed, high brightness, good color temperature, long service life and simple structure.
Description
Technical field
The utility model relates to a kind of LED street lamp, relates in particular to a kind of air-cooled LED lamp that has.
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 a series of advantages such as few, photochromic pure, all solid state, the light weight of power consumption, volume are little, environmental protection.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 promptly 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 utility model provides a kind of air-cooled LED lamp, and 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 purpose of the present utility model also provides the heat transfer medium in a kind of heat pipe.
The purpose of this utility model is achieved through the following technical solutions, this air-cooled LED 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 a 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 kind of embodiment of the present utility model 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.
The beneficial effects of the utility model: adopt the lamp housing heat radiation to compare with traditional LED lamp, what air-cooled 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.
