problems for LED lgihts' heat-sink

Put LED sources into lights is a good energy-saving method, many countries and mny companies are focus on developed this kind of lights, but one thing must concerned is that the radiation heat-sink of LED light are a big problems which all companies come accrossed and tries all best t o solved, such as Osram, cree, philips and so on, good heat-sink can bright long life span and better energy-saving. So it worth all the best to do it.

The existed conduction heat-sink of LED lamp is just in view of the internal conduction only, that is conducing the heat of LED lamp t othe radiator fin and to apply the radiator fin to bring convection heat-sink.

Above mentioned methods are not the better ways for LED lamp heat-sink, in fact, LED lamps inside the bulbs, as a result the heat is difficult to go out, this is because of the temperature inside the bulb reached a balance after lighted a period a time, and the lamp convered the LED to make a bad air flow inside the bulb, so that the high temperature of LED make a bad influence to the LED lamp and cause a short-life to the related electrical parts.

The existed deat-sink oif LED lamp design is just limited to the internal conduction heat-sink, it is seldom ot design to conduct the heat to the lamp base to help LED lamp heat-sink, so that, it makes a bad conduction heat-sink.

Because the luminaries will make a bad convection heat-sink, there are many LED lamps makers to build holes on the luminaries to obtain a better heat-sink, but this design also bring another problems, that is the dirt will cover on the luminaires, the dirt will also cause the bad convection heat-sink, the main factor of convection heat-sink is AIR-FLOW.

The air is not flowing inside luminaries, if will cause the convection heat-sink worse even to build lots holes on the luminaries, for solving this problem, it needs to assembly a mini cooling fan inside to heat-dissapation, but it will increase the cost, owing to above point out problems.
