chips of LED high
made by mung bean sized lamp beads. Can we use less beads with higher power to
achieve the same lighting effect? From
the aspect of cost, the cost of LED
higher power is higher than that of same number lower power LED lights. This is
due to two aspects: The first is the cost of LED lamp beads. The technology for
LED chips with higher power is not mature yet; therefore the LED lights are not
widely applied since the price is high. Higher power demands more for packaging
material, so overall the lamp beads with high power is of low cost performance.
The other reason is LED lights with higher power need aluminum cooling fin or
even power cooler. Those with lower power would simply need normal aluminum
substrate and natural cooling.
