Background technology
LED application is constantly subjected to the puzzlement of heat dissipation problem, and heat dissipation problem seriously affects light efficiency and the longevity of LED light source
Life, the radiating of LED will typically rely on radiator, and traditional radiator is typically all the cylindrical shape closed, and outside can be distributed one
A little fins, although having reached basic radiating purpose, radiator close cause radiator inner air can not in time with outside
The air circulation on boundary, just cause radiating efficiency low, cause LED light source and power source temperature too high, so as to have influence on LED light efficiency
And the life-span, and in order that radiator effect becomes more preferable, existing radiator can also open up heat emission hole on the outer wall, and heat emission hole is set
That counts is too big, and radiator has not had the effect of dust and moisture again, and heat emission hole designs too small, though serve to LED
The effect of dust and moisture, but what heat caused by LED still can not be unobstructed distributes, and also heat emission hole is too small, the time
One length, it is easy to can be blocked by dust, cause heat emission hole not reach the purpose of radiating, this certainly will also have influence on the use of LED
Life-span.
