How good are the COB LED grow lights?
Integrated LED is generally a different name for COB LED in the market, but in fact it cannot describe the characteristics of COB LED clearly. COB refers to Chip-On-Board, which directly encapsulates a small power chip on an aluminum substrate for fast heat dissipation, with a small chip area, high efficiency of heat dissipation and low driving current. Therefore, it has high heat dissipation with low thermal resistance and high thermal conductivity. Compared with ordinary SMD LED, it features higher brightness, lower thermal resistance ( 6â/W ), lower light attenuation, higher apparent index, perfect light spot and long life.
Low-power LEDs of SMD uniformly arranged on the aluminum substrate also known as integrated LED. In fact this integration is only soldering the SMD LED package ( finished LEDs ) on the aluminum substrate ( as shown in Figure 1 below ), instead of COB LEDs; COB directly packages the small power chip ( LED chip ) onto the aluminum substrate ( as shown in fig. 2 ). All COB LEDs are integrated LEDs, but not all integrated LEDs are COB.
The SMD LED is a single bead of patch LED lamp. COB LED is integrated with several SMD LED chips and packaged into a whole, which is smaller in size and higher in brightness than SMD LEDs with the same power.
