Technical field
A kind of unpowered turbine ventilated LED road lamp heat radiating device of the present invention is to be the road illuminating lamp of light source with the large-power light-emitting diodes; utilize unpowered turbine ventilated system to discharge heat in the road illuminating lamp; to play the life-span of protection large-power light-emitting diodes; reduce the decay of brightness; reduce the maintenance of light fixture; increase the benefit of energy-saving illumination, well solved the heat dissipation problem of great power LED.
Background technology
The municipal road lamp market statistics shows that China's city illumination has the street lamp more than 1,500 ten thousand, and growth rate in recent years estimates like this that more than 20% the market scale of national annual illuminating street lamp is not less than 5,000,000,000 yuan.If the street lamp that does not belong to street lamps at different levels place management such as factories and miness, government departments and institutions, sub-district etc. are counted at interior street lamp, then quantity is more huge.Add the illumination of other incandescent lamps, fluorescent lamp, total amount, can be saved more than electric power resource 1,000 hundred million kilowatt hours if all replace to the LED illuminating product more than 9,000 ten thousand every year, is equivalent to the annual generated energy of Three Gorges Projects fully loaded.But because the defective of luminous tube production technology, the high-power light-emitting pipe produces a lot of heats when illumination light-emitting, the heat that distributes when wherein 80% electric energy becomes illumination, but heat is if can not well discharge the life-span that will influence LED.The thermal resistance of present 1 watt luminous tube generally 15 degree/watt below, that is to say that add 1 watt electrical power for 1 watt luminous tube, tube core is than only high 15 degree of temperature of shell.According to the heatproof level of present luminous tube die material, die temperature is no more than the just work of energy long-term safety of 75 degree, and the life-span of the low more LED of the temperature of tube core is just long more.
The traditional lighting lamp outer casing all is a whole cover, can not efficiently radiates heat, and it is the shortcoming that light source illumination lamp fitting can not efficiently radiates heat that the unpowered turbine ventilated LED road lamp heat radiating device of the present invention has overcome traditional light emitting diode.And on making, just on original street lamp shell, reequip, the risk of having avoided the disposable blindness that pack alloy die sinking expense is very high again to drop into has reduced production cost, can recycle existing streetlamp housing again simultaneously.
Summary of the invention
The objective of the invention is to overcome the shortcoming of former traditional lighting shell, thereby provide a kind of unpowered turbine ventilated LED road lamp heat radiating device, the heat dissipation problem that has promptly solved high-power LED street lamp has been avoided the risk of the disposable blindness input that pack alloy die sinking expense is very high again again, has reduced production cost.The invention is backed down the ventilating skylight design on being, the principle of the heat in the lamp outer casing by unpowered turbine discharged from the lining.Unpowered turbine can rotate under the drive of natural wind, also can be in shell temperature when being higher than outside the shell temperature, heat is discharged in rotation thereby the elements that hot-fluid makes progress drives turbine.Below unpowered turbine, at the neck mouth that connects two layers of overcoat are arranged, can be under level or level at street lamp shell top adjusted turbine, make its maintenance water line and be able to more effectively rotate heat extraction, the centrifugal force that produces when the turbo blade running of unpowered turbine, rainwater can't penetrate into housings.
Technical solution of the present invention is:
This unpowered turbine ventilated LED road lamp heat radiating device comprises lighting 9, unpowered Air drawing fan device 10.Unpowered Air drawing fan device 10 is placed on the shell 3, comprises adjusting seat 2, unpowered Air drawing fan 8.Adjust seat and be arranged on above the lighting 9, be used for adjusting the direction that unpowered turbine Air drawing fan 8 is installed.Unpowered Air drawing fan 8 is arranged on to be adjusted above the seat 2, comprises turbo blade 1 and convex tendon 11, and turbo blade 1 is provided with on the unpowered Air drawing fan 8, under the effect of hot-air or wind-force, produces running, disperses the heat that light emitting diode 5 produces.Convex tendon 11 is arranged on turbo blade 1 and is provided with the vertically convex tendon 11 of projection of 2 rows, and the centrifugal force of Chan Shenging makes rainwater drain outward along convex tendon 11 and can't penetrate into shell 3 the insides in the running.
Compared with the prior art the present invention has the following advantages:
General LED road lamp cooling method has fan, aluminium sheet, heat pipe, loop heat pipe.The fan cost is low but needs configuration dynamical system can produce noise, and waterproof and service life can be subjected to the passing of time and have a greatly reduced quality; Aluminium sheet weight is heavier; Heat pipe is subjected to moulding restriction meeting because of conventional heat pipe can't cooperate light fitting shape, causes adducible light fixture form range to diminish and limited by the gravity problem; The loop heat pipe cost is higher, now also is not suitable for applying to commercialization stage.And the bottleneck of its development of great power LED product now is exactly a heat dissipation problem, as long as can address this problem quality and the service life that could improve LED.The present invention utilizes the unpowered turbine ventilated heat heat radiation that well light emitting diode is given out, and does not need die sinking tool flower cost in addition, and is simple in structure, easy for installation, with low cost, be not subjected to the restriction of environmental factor, well solved the problem of the heat radiation of great power LED.
