Abstract
The invention relates to an LED street lamp utilizing radiating fins and a heat pipe to conduct heat. In the invention, an LED controller 4 conveys a DC constant-current voltage to an LED 6; the LED 6 is electrified to give out lights; the working LED 6 generates harmful heat which is absorbed by an upper shell LED installation panel 7; a liquid heat-conducting medium 2 in the heated inner cavity of a heat pipe 1 is warmed up and evaporated; the heat is rapidly conducted to the upper end of the heat pipe 1; radiating fins 3 at the upper end of the heat pipe exchange heat with the surrounding air; the air takes away the heat to cool the LED 6, thus effectively prolonging the service life of the LED 6 and improving the lumens depreciation of the LED 6; and a lower shell 9 and a lampshade 8 are tightly matched with an upper shell 10, thus precluding the invasion of water and dust and ensuring the safe and effective work of electrical components in the lamp.
Description
Affiliated technical field
The present invention relates to a kind of heat pipe for thermal conductivity, the LED outdoor lights and the indoor illumination of fin heat radiation.
Background technology
At present, along with the increasing of national energy-saving and emission-reduction, people strengthen gradually to the consciousness of energy-conserving and environment-protective.The LED green illumination product of " fashion, energy-saving and environmental protection " has become the theme of illuminating industry production development.As third generation solid state lighting device, it has characteristics such as low in energy consumption, that volume is little, the life-span is long progressively replace incandescent and fluorescent lamp.Though the LED light fixture is also arranged on the market now to be produced, single power 1W of LED is made up of the plurality of LEDs serial or parallel connection, because of there is thermal resistance in metal fin to 3W, the heat temperature difference on the fin lower curtate is transmitted to fin that produces from led chip reaches 25 ℃, the non-constant of the effect of heat radiation.Cause the too high damage of led chip Yin Wendu, cause luminous efficacy to reduce, the light decay that quickens LED is old, has seriously shortened the service life of LED.
Summary of the invention
In order to make the work that the LED lamp can be steady in a long-term, really embody the advantage at the bottom of long, the energy consumption of LED lamp life-span.The heat that produces in the time of just LED must being worked effectively is dispersed in the air as early as possible and goes, and the invention provides a kind of LED street lamp utilizing radiating fins and heat pipe to conduct heat.As everyone knows, under vacuum state, at the bottom of the boiling point of liquid, the latent heat of vaporization of material of the same race is than sensible heat height.Heat-pipe apparatus in this product is applied on the light fixture according to above principle design.
The technical solution adopted for the present invention to solve the technical problems: at upper shell and upper shell LED installation panel and heat pipe and fin is one-body molded by die casting.LED is installed in parallel on the upper shell LED installation panel bottom surface, carries direct current constant current operating voltage by the LED power-supply controller of electric to LED, and LED obtains operating voltage and lights luminous.LED during work has produced a part of heat, these are transmitted to heat pipe to the heat that LED life-span itself and optical attenuation impact through upper shell LED installation panel, the heat pipe liquid thermal conductivity media is heated vaporization rapidly the heat transferred fin, and the heat of fin contacts with ambient air and realized heat exchange.The conduction that goes round and begins again is reduced to the heat that LED produces in the temperature range of its long-term safety steady operation, thereby has guaranteed the work of LED low consumption longevity.
The invention has the beneficial effects as follows, the heat that has produced when having solved LED work, prolonged the stable working life of led chip long-term safety, improved the light decay that led chip Yin Wendu raises and causes, complete embody long, energy consumption of LED solid light source life-span at the bottom of, the characteristics of environmental protection.
Description of drawings
The present invention is further described with enforcement below in conjunction with accompanying drawing.
Fig. 1. be the structural map of the embodiment of the invention.
In the drawings, heat pipe 1, liquid thermal conductivity media 2, fin 3, LED power-supply controller of electric 4, LED 6, upper shell LED installation panel 7, lampshade 8, lower house 9, upper shell 10,
The specific embodiment
In Fig. 1, LED power-supply controller of electric 4 is carried direct current constant current voltage to LED 6, LED 6 obtains operating voltage and lights luminous, produced heat behind the chip operation of LED 6, this heat is through absorbing with the LED 6 parallel upper shell LED installation panels of being close to 7, be heated with the heat pipe 1 of upper shell LED installation panel 7 integrally castings, the vaporization of being heated of heat pipe 1 intracavity liquid heat-conducting medium 2, rapidly heat is transmitted to heat pipe 1 upper end, heat pipe 1 upper end and fin 3 are cast into one, fin 3 is heated and the ambient air convective heat exchange at once, absorption of air the heat of fin 3, the heat that LED 6 is produced that goes round and begins again transmits fast, thereby has guaranteed that LED 6 long-term safety effectively work.Lampshade 8 and lower house 9 closely cooperate with upper shell 10 and have stopped the invasion of water and dust, guarantee that the electric component long-term safety of lamp interior effectively works, light pole installing hole 5 is used for the LED street lamp utilizing radiating fins and heat pipe to conduct heat fixed installation, and is LED power-supply controller of electric 4 power line input holes.
