Chip size
|
1*10mm
|
7.5*7.5mm
|
|
Conclusion
|
Similar total thermal power, LED has bigger heat dissipation are and smaller heat flow density.
|
||
Heat transfer patch
|
Pass to the bottom and rear Average path is 1.5mm
|
Pass to the bottom Average path is just 0.2mm
|
|
Conclusion
|
LED has very short heat transfer path, lower thermal resistance and much higher efficiency of heat dissipation.
|
||
Mechanical damage
|
Stress
|
Rectangle, high length-width ratio. Under stress of thermal deformation and thermal fatigue, chips easily desoldering or broken in
pulsed working |
Square, 1:1 length-width ratio. Extra thin chip and large soldering area firmly but low stress.
|
Conclusion
|
Because of chip structure, LED chip’s stress is smaller than diode laser

Light emitting area
|
Size 0.01*0.1mm High brightness, foreign body pollution can cause light-emitting surface burned
|
Size 5*5mm Brightness is just similar to normal LED lamp of flashlight, slight dust will not being ignited to burn the lighting
surface |
|
|
Conclusion
|
Because of surface emitting, the brightness of LED light emitting area is much smaller than diode laser.
|
|
Chain damage
|
|
Not like diode laser, for LED chips, single area’s failure does not affect other emitting area
