Traditional LED street lamp design mainly focus on the LED on the number of lumens, less attention while for heat dissipation.
In fact, the LED on the number of lumens are rapidly increasing.
In 2009, production of LED single tile lumens number has reached 100 lumens, and that figure is growing rapidly.
And the matching theory of heat transfer system is mature, we can use the means of heat transfer and basic clear: conduction, convection, radiation, and phase change heat transfer.
On the heat transfer or thermal problems, therefore, we can take measures are visible, limited.
LED street lamp cooling technology, the use of more general way for thermal conductive plate, is a 5 mm thick copper plate, is actually mean temperature plate, the heat source temperature drop;
Also with a heat sink for cooling, but too much weight.
Weight on the street lamp system is very important, because of the high solar street light
is 9 meters, if too much risk increases, especially in typhoon, earthquake can cause accidents.
Domestic manufacturers adopt the world's first needle cooling technology, acicular radiator cooling efficiency than conventional flake radiator has a great range, can make the LED junction temperature is lower than ordinary radiator more than 15 ℃, and the waterproof performance is better than ordinary aluminum radiator, also improved on the weight and volume.
In addition, in view of the high power LED lamps and lanterns of the development of graphite heat sink also has a good thermal conductivity and thermal performance.
By adding the cooling pattern mainly has: natural convection fan forced cooling, heat pipe, and the loop heat pipe cooling, etc.
Equipped with fans forced cooling way system complexity, low reliability, high heat pipe and the way of the loop heat pipe cooling costs.
And street lamp which has outdoor use at night, the radiating surface is located in the lateral and smaller size restriction is beneficial to the advantages of the air natural convection, so the LED street lamp suggested that as far as possible choose natural convection cooling way.
