Description
Technical field
The utility model relates to a kind of street lamp, relates in particular to a kind of with the street lamp of LED as light source.
Background technology
" heat pipe " is a kind of heat transfer element of the G.M.Grover invention of U.S. LosAlamos National Laboratory in 1963, it has made full use of the Rapid Thermal hereditary property of heat-conduction principle and refrigeration filling, be delivered to rapidly outside the thermal source through the heat of heat pipe with thermal objects, its capacity of heat transmission surpasses any known metal.Heat pipe is exactly the quick conduction that realizes heat by the liquid-gas phase transition of working medium, and typical heat pipe is made up of shell, imbibition core and end cap.During manufacturing be pumped into 1.3 in the pipe * (after the negative pressure of the Pa of 10-1 ~ 10-4), fill, make to be sealed after being full of liquid in the imbibition core capillary porous material of being close to inside pipe wall with an amount of hydraulic fluid.One end of pipe is evaporator section (bringing-up section), and the other end is condensation segment (cooling section).
The characteristics that LED has efficiently, energy-saving and environmental protection, life-span are long, along with the quick raising of the luminous efficiency of LED, increasing street lamp adopts LED as light source.But there are a lot of technical deficiencies in present LED street lamp, and is poor as heat dispersion, and weight is too heavy, the installation and transportation inconvenience, and environmental suitability is poor, can not automatically cleaning, light loss is big etc., for example:
