24 hours non-stop working
Wide heat dissipation surface, can realize all around clock work with “contant temperature”
Few after sales concerns
No deionized water, no filters, no consumables, etc. No laser source burning concern

Maintenance
|
Handle
|
Always need change light tube
|
Laser generator is easily damaged, need replace every 1 to 2 years
|
If normal use and regular maintenance, handle has the same lifespan as device
|
Filter
|
No need
|
Need often change filter and deionizer, if not, laser generator is easily damaged
|
No need

Chip size
|

|
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
