Why use LED lamp light source patch
The patch LED can be fabricated directly on the aluminum substrate and directly cooled to the aluminum substrate to save heat, packaging costs and reduce thermal conductivity losses.
Chip heat dissipation is better than plug-in, long life
In a large number of automated production, the packaging cost of the patch LED itself and the cost of soldering to the circuit board are lower than those of the small power LED.
Patch LED because of small footprint, the unit area can increase the number of LED series, which has a small power LED lamps power factor has improved benefits.
SMD LED light emitting angle is 180 degrees (theoretical value), the diffuse reflective light through the tubular lamp cup, directed and no lens dazzling, very suitable for general lighting purposes. Of course, the cost of the lens is also saved.
