Whereby, the test result done of the utility model and existing LED 200W stage lighting:

1. can make lamp temperatures reduce by 21%;

2. level of noise (dB) reduces by 11%;

3. power consumption saves 3.1%;

4. thermal resistance improves 26.7%;

5. improveing the positive temperature difference of light fixture is 34.2 ℃;

6. promote 3 times of theoretical life-spans of light fixture Arrhenius.So generally speaking, the effect of the multinomial positive index of the utility model tool is promoted.
